Abstract: By closing and opening ion channels, electric eels are able to convert ion concentration gradients into electricity. Inspired by electric eels, considerable artificial sub-nanoscale ion channels with high ion selectivity and transportation efficiency have been designed for harvesting the osmotic energy between ionic solutions of different salinities, but constructing smart ion-gated sub-nanochannels for effective ion transport is still a huge challenge.

Construction of angstrom-scale ion channels with versatile pore configurations and sizes by metal-organic frameworks
Publisher: Springer Science and Business Media LLC
Date: 18-01-2023
DOI: 10.1038/S41467-023-35970-X
Abstract: Controllable fabrication of angstrom-size channels has been long desired to mimic biological ion channels for the fundamental study of ion transport. Here we report a strategy for fabricating angstrom-scale ion channels with one-dimensional (1D) to three-dimensional (3D) pore structures by the growth of metal-organic frameworks (MOFs) into nanochannels. The 1D MIL-53 channels of flexible pore sizes around 5.2 × 8.9 Å can transport cations rapidly, with one to two orders of magnitude higher conductivities and mobilities than MOF channels of hybrid pore configurations and sizes, including Al-TCPP with 1D ~8 Å channels connected by 2D ~6 Å interlayers, and 3D UiO-66 channels of ~6 Å windows and 9 − 12 Å cavities. Furthermore, the 3D MOF channels exhibit better ion sieving properties than those of 1D and 2D MOF channels. Theoretical simulations reveal that ion transport through 2D and 3D MOF channels should undergo multiple dehydration-rehydration processes, resulting in higher energy barriers than pure 1D channels. These findings offer a platform for studying ion transport properties at angstrom-scale confinement and provide guidelines for improving the efficiency of ionic separations and nanofluidics.
A multinational Delphi consensus to end the COVID-19 public health threat
Publisher: Springer Science and Business Media LLC
Date: 03-11-2022
DOI: 10.1038/S41586-022-05398-2
Abstract: Despite notable scientific and medical advances, broader political, socioeconomic and behavioural factors continue to undercut the response to the COVID-19 pandemic 1,2 . Here we convened, as part of this Delphi study, a erse, multidisciplinary panel of 386 academic, health, non-governmental organization, government and other experts in COVID-19 response from 112 countries and territories to recommend specific actions to end this persistent global threat to public health. The panel developed a set of 41 consensus statements and 57 recommendations to governments, health systems, industry and other key stakeholders across six domains: communication health systems vaccination prevention treatment and care and inequities. In the wake of nearly three years of fragmented global and national responses, it is instructive to note that three of the highest-ranked recommendations call for the adoption of whole-of-society and whole-of-government approaches 1 , while maintaining proven prevention measures using a vaccines-plus approach 2 that employs a range of public health and financial support measures to complement vaccination. Other recommendations with at least 99% combined agreement advise governments and other stakeholders to improve communication, rebuild public trust and engage communities 3 in the management of pandemic responses. The findings of the study, which have been further endorsed by 184 organizations globally, include points of unanimous agreement, as well as six recommendations with % disagreement, that provide health and social policy actions to address inadequacies in the pandemic response and help to bring this public health threat to an end.

Exceptional hydrogen evolution in acid enabled by a multi-function-site complex oxide via atomic-scale hydrogen spillover
Publisher: Research Square Platform LLC
Date: 13-07-2021
DOI: 10.21203/RS.3.RS-670823/V1
Abstract: Improving the catalytic efficiency of platinum (Pt) for hydrogen evolution reaction (HER) is crucial for water splitting technologies, and hydrogen spillover has emerged as a new frontier in designing the binary-component Pt/support HER electrocatalysts. However, such binary catalysts always suffer from long reaction pathway, undesirable interfacial barrier, and complicated synthesis processes. Here we report a single-phase complex oxide La 2 Sr 2 PtO 7+δ as a high-performance HER electrocatalysts in acidic media via a unique atomic-scale hydrogen spillover effect between multifunctional catalytic sites. With insights from theoretical calculations, a possible synergistic mechanism involving the hydrogen spillover channel from O La site→La-Pt bridge site→Pt site is proposed namely, the O La site enriches proton, the La-Pt bridge site with thermo-neutral H* adsorption facilitates the hydrogen spillover and H 2 generation, and Pt site favors the final H 2 desorption. Benefiting from such unusual phenomenon, the resulting La 2 Sr 2 PtO 7+δ exhibits an exceptional HER electrode activity with low overpotential of 13 mV at 10 mA cm − 2 and small Tafel slope of 22 mV dec − 1 , and significantly enhanced intrinsic activity and durability than commercial Pt black catalyst.
Bifunctional plasmonic-magnetic particles for an enhanced microfluidic SERS immunoassay
Publisher: Royal Society of Chemistry (RSC)
Date: 2017
DOI: 10.1039/C7NR01511A
Abstract: Surface-Enhanced Raman Scattering (SERS) is emerging as a promising strategy for the quantification of immunoglobulin G (IgG) due to its inherent high sensitivity and specificity however, it remains challenging to integrate SERS detection with a microfluidic system in a simple, efficient and low-cost manner. Here, we report on a novel bifunctional plasmonic-magnetic particle-based immunoassay, in which plasmonic nanoparticles act as soluble SERS immunosubstrates, whereas magnetic particles are for promoting micromixing in a microfluidic chip. With this novel SERS immunosubstrate in conjunction with the unique microfluidic system, we could substantially reduce the assay time from 4 hours to 80 minutes as well as enhance the detection specificity by about 70% in comparison to a non-microfluidic immunoassay. Compared to previous microfluidic SERS systems, our strategy offers a simple microfluidic chip design with only one well for mixing, washing and detection.

A Magnetic Gated Nanofluidic Based on the Integration of a Superhydrophilic Nanochannels and a Reconfigurable Ferrofluid
Publisher: Wiley
Date: 14-12-2018
Abstract: The design of intelligent gating in nanoscale is the subject of intense research motivated by a broad potential impact on science and technology. However, the existing designs require complex modification and are unstable, which restrict their practical applications. Here, a magnetic gated nanofluidic is reported based on the integration of superhydrophilic membranes and reconfigurable ferrofluid, which realizes the gating of the nanochannel by adjusting the steric configuration of the ferrofluid. This system could achieve ultrahigh gating ratio up to 10 000 and excellent stability up to 130 cycles without attenuation. Experiments and theoretical calculations demonstrate that the switch is controlled by the synergy of magnetic force and the interfacial tension. The introduction of ferrofluid and superhydrophilic nanochannels in this work presents an important paradigm for the nanofluidic systems and opens a new and promising avenue to various developments in the fields of materials science, which may be utilized in medical devices, nanoscale synthesis, and environmental analysis.

Publisher: Wiley
Date: 08-04-2021
Abstract: Efficient resolution of racemates of chiral molecules is of great significance in the pharmaceutical, agrochemical, fragrances, and food additives industries. Emerging homochiral porous materials such as metal–organic frameworks, covalent‐organic frameworks, porous‐organic cages, and metal‐organic cages with ultrahigh surface area, controllable pore chemistry and le chiral recognition sites are promising for efficient chiral resolution, which display excellent properties for chiral separation applications. This review summarizes the design and synthesis strategies for the construction of homochiral porous materials, including direct synthesis, post‐synthesis, and chiral induction synthesis. Following this, applications of emerging homochiral porous materials, including enantioselective adsorption, chiral chromatography, and membrane‐based chiral separation are highlighted. Finally, the challenges in this area are discussed, with future perspectives provided.

Pyro-layered heterostructured nanosheet membrane for hydrogen separation
Publisher: Springer Science and Business Media LLC
Date: 15-04-2023
DOI: 10.1038/S41467-023-37932-9
Abstract: Engineering different two-dimensional materials into heterostructured membranes with unique physiochemical properties and molecular sieving channels offers an effective way to design membranes for fast and selective gas molecule transport. Here we develop a simple and versatile pyro-layering approach to fabricate heterostructured membranes from boron nitride nanosheets as the main scaffold and graphene nanosheets derived from a chitosan precursor as the filler. The rearrangement of the graphene nanosheets adjoining the boron nitride nanosheets during the pyro-layering treatment forms precise in-plane slit-like nanochannels and a plane-to-plane spacing of ~3.0 Å, thereby endowing specific gas transport pathways for selective hydrogen transport. The heterostructured membrane shows a high H 2 permeability of 849 Barrer, with a H 2 /CO 2 selectivity of 290. This facile and scalable technique holds great promise for the fabrication of heterostructures as next-generation membranes for enhancing the efficiency of gas separation and purification processes.

Mesoporous silica spheres from colloids
Publisher: Elsevier BV
Date: 04-2007
DOI: 10.1016/J.JCIS.2007.01.009
Abstract: A novel method has been developed to synthesize mesoporous silica spheres using commercial silica colloids (SNOWTEX) as precursors and electrolytes (ammonium nitrate and sodium chloride) as destabilizers. Crosslinked polyacrylamide hydrogel was used as a temporary barrier to obtain dispersible spherical mesoporous silica particles. The influences of synthesis conditions including solution composition and calcination temperature on the formation of the mesoporous silica particles were systematically investigated. The structure and morphology of the mesoporous silica particles were characterized via scanning electron microscopy (SEM) and N2 sorption technique. Mesoporous silica particles with particle diameters ranging from 0.5 to 1.6 microm were produced whilst the BET surface area was in the range of 31-123 m2 g-1. Their pore size could be adjusted from 14.1 to 28.8 nm by increasing the starting particle diameter from 20-30 nm up to 70-100 nm. A simple and cost effective method is reported that should open up new opportunities for the synthesis of scalable host materials with controllable structures.

Thermo-responsive Membranes with Switchable Superhydrophilicity and Superhydrophobicity for Oil–Water Separation
Publisher: The Royal Society of Chemistry
Date: 16-04-2019
DOI: 10.1039/9781788016377-00362
Abstract: Oil–water separation remains key in the development of technology for a range of applications. In this chapter, thermally responsive membranes with switchable superwettabilities used for controllable oil–water separation will be discussed. Superwetting membranes have been shown to be energy-efficient and cost-effective for the separation of oil–water mixtures or oil–water emulsions because the separation mechanism is based on the different interfacial effects of oil or water on the superwetting surface. These membranes show not only excellent separation efficiency, but also ultrahigh permeation flux. In recent years, on–off switchable separation of oil–water mixtures, separation of different kinds of oil-in-water emulsions and water-in-oil emulsions with the same membrane, and tuneable permeation flux have been achieved by introduction of a thermally responsive ability into the superwetting membranes. The challenges in this area are also outlined for further development of thermo-responsive membranes with superwetting surfaces for controllable oil–water separation and practical applications.

Thermoresponsive Amphoteric Metal-Organic Frameworks for Efficient and Reversible Adsorption of Multiple Salts from Water
Publisher: Wiley
Date: 10-07-2018
Abstract: Regenerable, high-efficiency salt sorption materials are highly desirable for water treatment. Here, a thermoresponsive, hoteric metal-organic framework (MOF) material is reported that can adsorb multiple salts from saline water at room temperature and effectively release the adsorbed salts into water at elevated temperature (e.g., 80 °C). The hoteric MOF, integrated with both cation-binding carboxylic groups and anion-binding tertiary amine groups, is synthesized by introducing a polymer with tertiary amine groups into the cavities of a water-stable MOF such as MIL-121 with carboxylic groups inside its frameworks. The hoterized MIL-121 exhibits excellent salt adsorption properties, showing stable adsorption-desorption cycling performances and high LiCl, NaCl, MgCl

Direct Electrodeposition of Porous Gold Nanowire Arrays for Biosensing Applications
Publisher: Wiley
Date: 26-01-2009
Abstract: Nanochannel alumina templates are used as templates for fabrication of porous gold nanowire arrays by a direct electrodeposition method. After modification with glucose oxidase, a porous gold nanowire-array electrode is shown to be an excellent electrochemical biosensor for the detection of glucose. The picture shows an SEM image of a nanowire array after removal of the alumina template by acid dissolution. We report the fabrication of porous gold nanowire arrays by means of a one-step electrodeposition method utilizing nanochannel alumina templates. The microstructure of gold nanowires depends strongly on the current density. The formation of porous gold nanowires is attributed to disperse crystallization under conditions of low nucleation rate. Interfacial electron transport through the porous gold nanowires is studied by electrochemical impedance spectroscopy. Cyclic voltammetric studies on the porous gold nanowire arrays reveal a low-potential electrocatalytic response towards hydrogen peroxide. The properties of the glucose oxidase modified porous gold nanowire array electrode are elucidated and compared with those of nonporous enzyme electrodes. The glucose oxidase modified porous gold nanowire-array electrode is shown to be an excellent electrochemical biosensor for the detection of glucose.

Nanoconfinement enabled non-covalently decorated MXene membranes for ion-sieving
Publisher: Springer Science and Business Media LLC
Date: 10-07-2023
DOI: 10.1038/S41467-023-39533-Y
Abstract: Covalent modification is commonly used to tune the channel size and functionality of 2D membranes. However, common synthesis strategies used to produce such modifications are known to disrupt the structure of the membranes. Herein, we report less intrusive yet equally effective non-covalent modifications on Ti 3 C 2 T x MXene membranes by a solvent treatment, where the channels are robustly decorated by protic solvents via hydrogen bond network. The densely functionalized (-O, -F, -OH) Ti 3 C 2 T x channel allows multiple hydrogen bond establishment and its sub-1-nm size induces a nanoconfinement effect to greatly strengthen these interactions by maintaining solvent-MXene distance and solvent orientation. In sub-1-nm ion sieving and separation, as-decorated membranes exhibit stable ion rejection, and proton-cation (H + /M n+ ) selectivity that is up to 50 times and 30 times, respectively, higher than that of pristine membranes. It demonstrates the feasibility of non-covalent methods as a broad modification alternative for nanochannels integrated in energy-, resource- and environment-related applications.

Thin-Film Nanocomposite Forward-Osmosis Membranes on Hydrophilic Microfiltration Support with an Intermediate Layer of Graphene Oxide and Multiwall Carbon Nanotube
Publisher: American Chemical Society (ACS)
Date: 13-09-2018
Abstract: A novel thin-film nanocomposite forward-osmosis (FO) membrane was fabricated on hydrophilic nylon microfiltration (MF) support by interfacial polymerization with the assistance of an intermediate layer of graphene oxide and multiwall carbon nanotube (GO/MWCNT). The chemical composition, structure, and surface properties of the synthesized FO membranes were studied using various characterization methods. It was found that the GO/MWCNT composite layer not only provided ultrafast nanochannels for water transport but also reduced the thickness of the polyamide layer by up to 60%. As a result, the novel FO membrane exhibited a higher water flux and lower reverse salt flux compared with the membrane synthesized without the GO/MWCNT intermediate layer. This method offers promising opportunities to fabricate thin-film composite membranes on microfiltration substrates for FO application with inhibited concentration polarization phenomenon and expected separation performance.
TEMPO‐Oxidized Cellulose Nanofibers: A Renewable Nanomaterial for Environmental and Energy Applications
Publisher: Wiley
Date: 24-04-2021
Abstract: TEMPO (2,2,6,6‐tetramethylpiperidine‐1‐oxyl radical)‐mediated oxidized cellulose nanofibers (TOCNFs), which are derived from abundantly available wood biomass, possess uniform and ultrafine diameters of 3–10 nm and high aspect ratios, and are functionalized with carboxyl groups. The fabrication process of TOCNFs is more environmentally friendly than that of other types of cellulose, such as microfibrillated cellulose (MFC) and cellulose nanocrystals (CNCs), and TOCNFs possess a more uniform and ultrafine diameter. In recent years, TOCNF‐based adsorbents, nanocomposites, and membranes have been studied extensively in various fields, such as environmental remediation, energy, and smart materials. This review summarizes the recent advances in the applications of TOCNFs in the abovementioned fields. In particular, the preparation, adsorption ability, and removal efficiency of TOCNF‐based absorbents, separation performance of various kinds of TOCNF‐based membranes, wide applications of TOCNFs in energy storage and conversion, and TOCNF‐based smart materials are discussed. The beneficial role of TOCNFs in the abovementioned applications is highlighted, including their low environmental impact, high aspect ratio, high strength, ability to be functionalized, and renewability. It is believed that this timely review will facilitate further research on the innovation and applications of TOCNFs in fields such as environmental remediation, energy, and smart materials.

Self-curled coral-like γ-Al2 O3 nanoplates for use as an adsorbent
Publisher: Elsevier BV
Date: 09-2015
DOI: 10.1016/J.JCIS.2015.03.065
Abstract: Biomimetic self-curled nanoplates assembled coral-like nanoporous γ-Al2O3 has been prepared by a solvothermal method using ethylene glycol (EG)H2O as the mixed solvent, followed by the annealing process. The resulting s les are composed of micro/nanostructured units (∼1.5 μm) with self-curled porous nanoplates on the surface. The volume ratio of EG to water in precursor solution is crucial for the formation of coral-like structure. The formation process is investigated to be an assembly process with self-curled nanoplates driven by adsorption of EG. Importantly, the coral-like porous γ-Al2O3 has high surface area of 64.18 m(2)/g and exhibits enhanced adsorption performance for efficient removal of heavy metal Hg(II) (49.15 mg/g). The removal capacity is higher than (∼2.5 times) those of commercial Al2O3 nanoparticles and hollow structured γ-Al2O3 prepared without EG (∼2.7 times). Further investigation shows adsorption behaviors of the coral-like γ-Al2O3 and the alumina hollow structure can be well described by Langmuir isotherm model, whereas that of commercial Al2O3 nanoparticles fits Freundlich isotherm model. This work not only provides an inspiration for high efficient biomimetic adsorbent but also presents a facile route for coral-like γ-Al2O3 preparation.

Fast and selective fluoride ion conduction in sub-1-nanometer metal-organic framework channels
Publisher: Springer Science and Business Media LLC
Date: 11-06-2019
DOI: 10.1038/S41467-019-10420-9
Abstract: Biological fluoride ion channels are sub-1-nanometer protein pores with ultrahigh F − conductivity and selectivity over other halogen ions. Developing synthetic F − channels with biological-level selectivity is highly desirable for ion separations such as water defluoridation, but it remains a great challenge. Here we report synthetic F − channels fabricated from zirconium-based metal-organic frameworks (MOFs), UiO-66-X (X = H, NH 2 , and N + (CH 3 ) 3 ). These MOFs are comprised of nanometer-sized cavities connected by sub-1-nanometer-sized windows and have specific F − binding sites along the channels, sharing some features of biological F − channels. UiO-66-X channels consistently show ultrahigh F − conductivity up to ~10 S m −1 , and ultrahigh F − /Cl − selectivity, from ~13 to ~240. Molecular dynamics simulations reveal that the ultrahigh F − conductivity and selectivity can be ascribed mainly to the high F − concentration in the UiO-66 channels, arising from specific interactions between F − ions and F − binding sites in the MOF channels.

Ultrafast rectifying counter-directional transport of proton and metal ions in metal-organic framework–based nanochannels
Publisher: American Association for the Advancement of Science (AAAS)
Date: 08-04-2022
Abstract: Bioinspired control of ion transport at the subnanoscale has become a major focus in the fields of nanofluidics and membrane separation. It is fundamentally important to achieve rectifying ion-specific transport in artificial ion channels, but it remains a challenge. Here, we report a previously unidentified metal-organic framework nanochannel (MOF NC) nanofluidic system to achieve unidirectional ultrafast counter-directional transport of alkaline metal ions and proton. This highly effective ion-specific rectifying transport behavior is attributed to two distinct mechanisms for metal ions and proton, elucidated by theoretical simulations. Notably, the MOF NC exhibits ultrafast proton conduction stemming from ultrahigh proton mobility, i.e., 11.3 × 10 −7 m 2 /V·s, and low energy barrier of 0.075 eV in MIL-53-COOH subnanochannels. Furthermore, the MOF NC shows excellent osmotic power–harvesting performance in reverse electrodialysis. This work expects to inspire further research into multifunctional biomimetic ion channels for advanced nanofluidics, biomimetics, and separation applications.

Genistein inhibits PDGF-stimulated proteoglycan synthesis in vascular smooth muscle without blocking PDGFβ receptor phosphorylation
Publisher: Elsevier BV
Date: 09-2012
DOI: 10.1016/J.ABB.2012.05.025
Abstract: The signaling pathways that regulate the synthesis and structure of proteoglycans secreted by vascular smooth muscle cells are potential therapeutic targets for preventing lipid deposition in the early stage of atherosclerosis. PDGF stimulates both core protein expression and elongation of glycosaminoglycan (GAG) chains on proteoglycans. In this study we investigated the effects of the tyrosine kinase inhibitor genistein on PDGF mediated receptor phosphorylation and proteoglycan synthesis in human vascular smooth muscle cells. We demonstrate that genistein does not block phosphorylation of the activation site of the PDGF receptor at Tyr(857) and two other downstream sites Tyr(751) and Tyr(1021). Genistein blocked PDGF-mediated proteoglycan core protein synthesis however it had no effect on GAG chain elongation. These results differ markedly to two other tyrosine kinase inhibitors, imatinib and Ki11502, that block PDGF receptor phosphorylation and PDGF mediated GAG elongation. We conclude that the action of genistein on core protein synthesis does not involve the PDGF receptor and that PDGF mediates GAG elongation via the PDGF receptor.

Toluene-assisted synthesis of RHO-type zeolitic imidazolate frameworks: synthesis and formation mechanism of ZIF-11 and ZIF-12
Publisher: Royal Society of Chemistry (RSC)
Date: 2013
DOI: 10.1039/C3DT52103F
Abstract: Toluene was discovered as the structure template for the synthesis of large-cage RHO-type zeolitic imidazolate frameworks (ZIF-11 and ZIF-12) in an alcohol-based solution where benzimidazole-toluene interactions play a decisive structure-directing role otherwise it leads to small-cage SOD-type ZIF-7 and ZIF-9 without toluene. The specific π-π interactions make toluene molecules adopt a specific and oriented arrangement in the unit cell. XRD intensity of the (100) plane is strongly dependent on the amount of toluene: apparent intensity degradation is observed after removing toluene by solvent exchange or thermal treatment, and the peak intensity is recoverable by filling of the pores with toluene vapor. More-polar methanol as compared to ethanol is favorable for the formation of RHO-type ZIFs due to the enhanced interactions between toluene and imidazolate linkers.

The hierarchical product consists of ZIF-L leaves with length of several micrometers, width of 1 ∼ 2 μm and thickness of ∼300 nm cross connected symmetrically. It was found that the hydrothermal temperature is crucial for the formation of such hierarchical nanostructure. The formation mechanism was investigated to be a secondary crystal growth process. The hierarchical ZIF-L has larger surface area compared with the two-dimensional (2D) ZIF-L leaves. Subsequently, the hierarchical ZIF-L exhibited enhanced CO

Solvation Effects on the Permeation and Aging Performance of PIM-1-Based MMMs for Gas Separation.
Publisher: American Chemical Society (ACS)
Date: 17-01-2019
Abstract: Membranes are particularly attractive for lowering the energy intensity of separations as they eliminate phase changes. While many tantalizing polymers are known, limitations in selectivity and stability slightly preclude further development. Mixed-matrix membranes may address these shortcomings. Key to their realization is the intimate mixing between the polymer and the additive to eliminate nonselective transport, improve selectivity, and resist physical aging. Polymers of intrinsic microporosity (PIMs) have inherently promising gas transport properties. Here, we show that porous additives can improve transport and resist aging in PIM-1. We develop a simple, low-cost, and scalable hyper-cross-linked polymer (poly-dichloroxylene, pDCX), which was hydroxylated to form an intimate mixture with the polar PIM-1. Solvent variation allowed control of physical aging rates and improved selectivity for smaller gases. This detailed study has allowed many interactions within mixed matrix membranes to be directly elucidated and presents a practical means to stabilize porous polymers for separation applications.

Forward osmosis desalination using polymer hydrogels as a draw agent: Influence of draw agent, feed solution and membrane on process performance
Publisher: Elsevier BV
Date: 2013
DOI: 10.1016/J.WATRES.2012.09.049
Abstract: We have previously reported the use of hydrogel particles as the draw agent for forward osmosis desalination. In the present work, the effects of draw agent, feed concentration and membrane on the process performance were systematically examined. Our results showed that the incorporation of carbon filler particles in polymer hydrogels led to enhanced swelling ratios of the draw agents and thus higher water fluxes in the FO process. The composite polymer hydrogel particles of sizes ranging from 100 μm to 200 μm as draw agents induced greater water fluxes in FO desalination as compared with those with larger particle sizes (500-700 μm). Similar to other types of draw solutes, as the salt concentration in the feed increased, the water flux created by the polymer hydrogel draw agent decreased the use of a cellulose triacetate forward osmosis membrane resulted in higher water flux compared with the use of a polyamide composite reverse osmosis membrane.

A Homochiral Poly(2‐oxazoline)‐based Membrane for Efficient Enantioselective Separation
Publisher: Wiley
Date: 18-01-2023
Abstract: Chiral separation membranes have shown great potential for the efficient separation of racemic mixtures into enantiopure components for many applications, such as in the food and pharmaceutical industries however, scalable fabrication of membranes with both high enantioselectivity and flux remains a challenge. Herein, enantiopure S ‐poly(2,4‐dimethyl‐2‐oxazoline) ( S ‐PdMeOx) macromonomers were synthesized and used to prepare a new type of enantioselective membrane consisting of a chiral S ‐PdMeOx network scaffolded by graphene oxide (GO) nanosheets. The S ‐PdMeOx‐based membrane showed a near‐quantitative enantiomeric excess ( ee ) (98.3±1.7 %) of S ‐(−)‐limonene over R ‐(+)‐limonene and a flux of 0.32 mmol m −2 h −1 . This work demonstrates the potential of homochiral poly(2,4‐disubstituted‐2‐oxazoline)s in chiral discrimination and provides a new route to the development of highly efficient enantioselective membranes using synthetic homochiral polymer networks.

Bacteriorhodopsin‐Inspired Light‐Driven Artificial Molecule Motors for Transmembrane Mass Transportation
Publisher: Wiley
Date: 16-11-2018
Abstract: In nature, biological machines and motors can selectively transport cargoes across the lipid membranes to efficiently perform various physiological functions via ion channels or ion pumps. It is interesting and challengeable to develop artificial motors and machines of nanodimensions to controllably regulate mass transport in compartmentalized systems. In this work, we show a system of artificial molecular motors that uses light energy to perform transmembrane molecule transport through synthetical nanochannels. After functionalizing the polymer nanochannels with azobenzene derivatives, these nanomachines exhibit autonomous selective transport behavior over a long distance upon simultaneous irradiation with UV (365 nm) and visible (430 nm) light. With new strategies or suitable materials for directed molecular movement, such device can be regarded as a precursor of artificial light-driven molecular pumps.

Polycrystalline Advanced Microporous Framework Membranes for Efficient Separation of Small Molecules and Ions
Publisher: Wiley
Date: 05-07-2019
Abstract: Advanced porous framework membranes with excellent selectivity and high permeability of small molecules and ions are highly desirable for many important industrial separation applications. There has been significant progress in the fabrication of polycrystalline microporous framework membranes (PMFMs) in recent years, such as metal-organic framework and covalent organic framework membranes. These membranes possess small pore sizes, which are comparable to the kinetic diameter of small molecules and ions on the angstrom scale, very low thickness, down to tens to hundreds of nanometers, highly oriented crystalline structures, hybrid membrane structures, and specific functional groups for enhancing membrane selectivity and permeability. Recent advances in the fabrication methods of advanced PMFMs are summarized. Following this, four emerging separation applications of these advanced microporous framework membranes, including gas separation, water desalination, ion separation, and chiral separation, are highlighted and discussed in detail. Finally, a summary and some perspectives of future developments and challenges in this exciting research field are presented.
Hydrogen spillover in complex oxide multifunctional sites improves acidic hydrogen evolution electrocatalysis
Publisher: Springer Science and Business Media LLC
Date: 04-03-2022
DOI: 10.1038/S41467-022-28843-2
Abstract: Improving the catalytic efficiency of platinum for the hydrogen evolution reaction is valuable for water splitting technologies. Hydrogen spillover has emerged as a new strategy in designing binary-component Pt/support electrocatalysts. However, such binary catalysts often suffer from a long reaction pathway, undesirable interfacial barrier, and complicated synthetic processes. Here we report a single-phase complex oxide La 2 Sr 2 PtO 7+δ as a high-performance hydrogen evolution electrocatalyst in acidic media utilizing an atomic-scale hydrogen spillover effect between multifunctional catalytic sites. With insights from comprehensive experiments and theoretical calculations, the overall hydrogen evolution pathway proceeds along three steps: fast proton adsorption on O site, facile hydrogen migration from O site to Pt site via thermoneutral La-Pt bridge site serving as the mediator, and favorable H 2 desorption on Pt site. Benefiting from this catalytic process, the resulting La 2 Sr 2 PtO 7+δ exhibits a low overpotential of 13 mV at 10 mA cm −2 , a small Tafel slope of 22 mV dec −1 , an enhanced intrinsic activity, and a greater durability than commercial Pt black catalyst.

Hydrophilic nanowire modified polymer ultrafiltration membranes with high water flux.
Publisher: American Chemical Society (ACS)
Date: 22-10-2014
DOI: 10.1021/AM505157W
Abstract: Germanate nanowires/nanorods with different lengths were synthesized and used as additives for the fabrication of polymer composite membranes for high-flux water filtration. We for the first time demonstrated that at a small nanowire/nanorod loading (e.g., <0.5 wt % on the basis of poly(ether sulfone)), the length of germinate nanowires was a key parameter in determining their migration and diffusion in the polymer solution, and thus affecting polymer precipitation in the membrane formation process. In particular, short Ca2Ge7O16 nanowires with an average length of 138.7 nm and an average diameter of 12.7 nm, and Zn2GeO4 nanorods with an average length of 400 nm and an average diameter of 18.7 nm quickly diffused out of the membrane, leading to a higher pore density on the active layer in comparison with the pristine membranes. The addition of short Ca2Ge7O16 nanowires resulted in greater pore sizes than the addition of Zn2GeO4 nanorods because the out-diffusion of the former was faster than that of the latter. In contrast, the addition of long Ca2Ge7O16 nanowires with lengths of several tens to hundreds of micrometers and an average of 27.3 nm was not effective in promoting the pore formation because of partial embedment of nanowires. Poly(ether sulfone) composite membranes prepared by adding a small amount of Zn2GeO4 nanorods exhibited dramatically enhanced water permeation without losing rejection property. For ex le, the poly(ether sulfone) (PES) composite membrane prepared with 0.3 wt % Zn2GeO4 nanorods exhibited the highest flux, 1294.5 LMH, which was 3.5 times of the pristine (PES) membrane (384.2 LMH). Our work provides a new strategy for developing high-performance ultrafiltration membranes for practical industrial filtration applications.

Robust Thermoresponsive Polymer Composite Membrane with Switchable Superhydrophilicity and Superhydrophobicity for Efficient Oil–Water Separation
Publisher: American Chemical Society (ACS)
Date: 06-01-2016
Abstract: Herein, we report for the first time on the fabrication of a robust, thermoresponsive polymer membrane produced by the combination of an elastic polyurethane (TPU) microfiber web and poly(N-isopropylacrylamide) (PNIPAM). PNIPAM hydrogel is evenly coated on the surface of TPU microfibers, and thus, the wettability of TPU-PNIPAM membrane is lified by taking advantage of the hierarchical structure and increased surface roughness. The TPU-PNIPAM membrane possesses switchable superhydrophilicity and superhydrophobicity as the temperature of membrane changes from 25 to 45 °C. The composite membrane is shown successfully able to separate a 1 wt % oil-in-water emulsion and 1 wt % water-in-oil emulsion at 25 and 45 °C, respectively, with a high separation efficiency of ≥99.26%. Furthermore, the composite membranes show excellent mechanical properties, and they are highly flexible and mechanically tough. The smart composite membranes reported here have shown great potential for further development for practical high-efficiency oil-water separations.

Abstract: Homochiral metal-organic framework (MOF) membranes have been recently reported for chiral separations. However, only a few high-quality homochiral polycrystalline MOF membranes have been fabricated due to the difficulty in crystallization of a chiral MOF layer without defects on porous substrates. Alternatively, mixed matrix membranes (MMMs), which combine potential advantages of MOFs and polymers, have been widely demonstrated for gas separation and water purification. Here we report novel homochiral MOF-polymer MMMs for efficient chiral separation. Homochirality was successfully incorporated into achiral MIL-53-NH

Carbon Nanotube Networks as Nanoscaffolds for Fabricating Ultrathin Carbon Molecular Sieve Membranes
Publisher: American Chemical Society (ACS)
Date: 29-05-2018
Abstract: Carbon molecular sieve (CMS) membranes have shown great potential for gas separation owing to their low cost, good chemical stability, and high selectivity. However, most of the conventional CMS membranes exhibit low gas permeance due to their thick active layer, which limits their practical applications. Herein, we report a new strategy for fabricating CMS membranes with a 100 nm-thick ultrathin active layer using poly(furfuryl alcohol) (PFA) as a carbon precursor and carbon nanotubes (CNTs) as nanoscaffolds. CNT networks are deposited on a porous substrate as nanoscaffolds, which guide PFA solution to effectively spread over the substrate and form a continuous layer, minimizing the penetration of PFA into the pores of the substrate. After pyrolysis process, the CMS membranes with 100-1000 nm-thick active layer can be obtained by adjusting the CNT loading. The 322 nm-thick CMS membrane exhibits the best trade-off between the gas permeance and selectivity, a H

DOI: 10.1038/S41467-020-14671-9
Abstract: Unlike inorganic crystals, metal-organic frameworks do not have a well-developed nanostructure library, and establishing their appropriately erse and complex architectures remains a major challenge. Here, we demonstrate a general route to control metal-organic framework structure by a solvent-assisted ligand exchange approach. Thirteen different types of metal-organic framework structures have been prepared successfully. To demonstrate a proof of concept application, we used the obtained metal-organic framework materials as precursors for synthesizing nanoporous carbons and investigated their electrochemical Na + storage properties. Due to the unique architecture, the one-dimensional nanoporous carbon derived from double-shelled ZnCo bimetallic zeolitic imidazolate framework nanotubes exhibits high specific capacity as well as superior rate capability and cycling stability. Our study offers an avenue for the controllable preparation of well-designed meta-organic framework structures and their derivatives, which would further broaden the application opportunities of metal-organic framework materials.
Simple fabrication of zeolitic imidazolate framework ZIF-8/polymer composite beads by phase inversion method for efficient oil sorption
Publisher: Elsevier BV
Date: 05-2017
DOI: 10.1016/J.JCIS.2017.01.006
Abstract: Zeolitic imidazolate framework ZIF-8 beads of 2-3mm in diameter were prepared using a simple one-step phase inversion method. The beads were fabricated by different amounts of ZIF-8 to polyether sulfone (PES) ratios. ZIF-8 played the role of an adsorbent while PES acted as a binder in the composite matrix to keep the ZIF-8 particles. Since ZIF-8 is highly hydrophobic, the beads floated on water and adsorbed oil droplets successfully. This efficient oil adsorption is attributed to the hydrophobicity and high surface area of ZIF-8 particles which can effectively adsorb oil droplets. Different characterization techniques were used to understand the textural properties of the composite beads. The FESEM analysis showed that ZIF-8 particles were well coated and dispersed into the polymer bead composites and some pores are created on the beads surface at higher loadings which facilitated high oil sorption. The nitrogen adsorption-desorption indicated that ZIF-8/PES beads had very high surface area which makes them suitable for adsorption applications. The ZIF-8/PES beads demonstrate easy handling and recycling compared to ZIF-8 powder and showed superior buoyancy and oil sorption capacity compared with natural sorbents like activated carbon. This study shows the phase inversion method can be applied to produce a variety of functional composite bead materials for specific applications like adsorption.

Sol–Gel Synthesis of Metal–Phenolic Coordination Spheres and Their Derived Carbon Composites
Publisher: Wiley
Date: 05-07-2018
Abstract: A formaldehyde-assisted metal-ligand crosslinking strategy is used for the synthesis of metal-phenolic coordination spheres based on sol-gel chemistry. A range of mono-metal (Co, Fe, Al, Ni, Cu, Zn, Ce), bi-metal (Fe-Co, Co-Zn) and multi-metal (Fe-Co-Ni-Cu-Zn) species can be incorporated into the frameworks of the colloidal spheres. The formation of coordination spheres involves the pre-crosslinking of plant polyphenol (such as tannic acid) by formaldehyde in alkaline ethanol/water solvents, followed by the aggregation assembly of polyphenol oligomers via metal-ligand crosslinking. The coordination spheres can be used as sensors for the analysis of nucleic acid variants with single-nucleotide discrimination, and a versatile precursor for electrode materials with high electrocatalytic performance.

Monovalent Cation–Phenolic Crystals with pH-Driven Reversible Crystal Transformation
Publisher: Wiley
Date: 28-08-2019
Abstract: The conversion of renewable plant polyphenol to advanced materials with tailorable properties and various functions is desirable and challenging. In this work, monovalent cation‐phenolic crystals contained K + or Na + ions were synthesized by using plant polyphenol as an organic source in alkaline solution. The crystal structure was resolved, showing a laminar crystal structure with M + as connecting nodes. The morphologies (e.g., rod‐like and spindle‐shaped) and chemical compositions of crystals could be tuned by changing the cations. Interestingly, these polymer crystals exhibited a pH‐driven reversible crystal transformation. They transformed into their protonated crystalline form under acidic conditions (e.g., pH 2) and went back to the cation‐bound crystalline form in alkaline solutions. Furthermore, the crystals proved excellent antioxidants and heavy metal ion adsorbents.

Seedless Synthesis of Monodispersed Gold Nanorods with Remarkably High Yield: Synergistic Effect of Template Modification and Growth Kinetics Regulation
Publisher: Wiley
Date: 02-2017
Abstract: Gold nanorods (AuNRs) are versatile materials due to their broadly tunable optical properties associated with their anisotropic feature. Conventional seed-mediated synthesis is, however, not only limited by the operational complexity and over-sensitivity towards subtle changes of experimental conditions but also suffers from low yield (≈15 %). A facile seedless method is reported to overcome these challenges. Monodispersed AuNRs with high yield (≈100 %) and highly adjustable longitudinal surface plasmon resonance (LSPR) are reproducibly synthesized. The parameters that influence the AuNRs growth were thoroughly investigated in terms of growth kinetics and soft-template regulation, offering a better understanding of the template-based mechanism. The facile synthesis, broad tunability of LSRP, high reproducibility, high yield, and ease of scale-up make this method promising for the future mass production of monodispersed AuNRs for applications in catalysis, sensing, and biomedicine.

Periodic oscillation of ion conduction of nanofluidic diodes using a chemical oscillator
Publisher: Royal Society of Chemistry (RSC)
Date: 2017
DOI: 10.1039/C7NR01343D
Abstract: Periodic ion-conduction oscillation of biological ion channels in a living system is essential for numerous life processes. Here we report an oscillatory nanofluidic system that can self-regulate its ion-conduction states under constant conditions. The oscillatory nanofluidic system is constructed by integrating a chemical oscillator into an artificial single nanochannel system. Oscillating chemical reactions of the pH oscillator carried out inside the nanochannel are used to switch the surface properties of the channel between highly and lowly charged states, thus realizing an autonomous, continuous and periodic oscillation of the ion conductance of the channel between high and low ion-conduction states. The ion-conduction switching is characterized by the periodic ion current oscillation of the nanochannel measured under constant conditions. The oscillation period of the nanofluidic devices decreased gradually with increasing the working temperature. This study is a potential step toward the ability to directly convert chemical energy to ion-conduction oscillation in nanofluidics. On the basis of these findings, we believe that a variety of artificial oscillatory nanofluidic systems will be achieved in future by integrating artificial functional nanochannels with erse oscillating chemical reactions.

Incorporation of Homochirality into a Zeolitic Imidazolate Framework Membrane for Efficient Chiral Separation
Publisher: Wiley
Date: 27-11-2018
Abstract: Homochiral metal–organic frameworks (MOFs) have gained much attention because of their chiral properties and disposition for chiral separation. However, the fabrication of high‐quality homochiral MOF membranes remains challenging because of the difficulty in controlling growth of MOF membranes with chiral functionalities. A homochiral zeolitic imidazolate framework‐8 (ZIF‐8) membrane is reported for efficient chiral separation. The membrane is synthesized by incorporating a natural amino acid, l ‐histidine ( l ‐His), into the framework of ZIF‐8. The homochiral l ‐His‐ZIF‐8 membrane exhibits a good selectivity for the R ‐enantiomer of 1‐phenylethanol over the S ‐enantiomer, showing a high enantiomeric excess value up to 76 %.

An artificial sodium-selective subnanochannel
Publisher: American Association for the Advancement of Science (AAAS)
Date: 27-01-2023
Abstract: Single-ion selectivity with high precision has long been pursued for fundamental bioinspired engineering and applications such as in ion separation and energy conversion. However, it remains a challenge to develop artificial ion channels to achieve single-ion selectivity comparable to their biological analogs, especially for high Na + /K + selectivity. Here, we report an artificial sodium channel by subnanoconfinement of 4′-aminobenzo-15-crown-5 ethers (15C5s) into ~6-Å-sized metal-organic framework subnanochannel (MOFSNC). The resulting 15C5-MOFSNC shows an unprecedented Na + /K + selectivity of tens to 10 2 and Na + /Li + selectivity of 10 3 under multicomponent permeation conditions, comparable to biological sodium channels. A co–ion-responsive single-file transport mechanism in 15C-MOFSNC is proposed for the preferential transport of Na + over K + due to the synergetic effects of size exclusion, charge selectivity, local hydrophobicity, and preferential binding with functional groups. This study provides an alternative strategy for developing potential single-ion selective channels and membranes for many applications.

Supramolecular self-assembly induced adjustable multiple gating states of nanofluidic diodes
Publisher: American Chemical Society (ACS)
Date: 09-12-2016
DOI: 10.1021/JACS.6B09601
Abstract: Artificial nanochannels, inheriting smart gating functions of biological ion channels, promote the development of artificial functional nanofluidic devices for high-performance biosensing and electricity generation. However, gating states of the artificial nanochannels have been mainly realized through chemical modification of the channels with responsive molecules, and their gating states cannot be further regulated once the nanochannel is modified. In this work, we employed a new supramolecular layer-by-layer (LbL) self-assembly method to achieve reversible and adjustable multiple gating features in nanofluidic diodes. Initially, a self-assembly precursor was modified into a single conical nanochannel, then host molecule-cucurbit[8]uril (CB[8]) and guest molecule, a naphthalene derivative, were self-assembled onto the precursor through an LbL method driven by host-enhanced π-π interaction, forming supramolecular monolayer or multilayers on the inner surface of the channel. These self-assemblies with different layer numbers possessed remarkable charge effects and steric effects, exhibiting a capability to regulate the surface charge density and polarity, the effective diameter, and the geometric asymmetry of the single nanochannel, realizing reversible gating of the single nanochannel among multiple rectification and ion-conduction states. As an ex le of self-assembly of supramolecular networks in nanoconfinements, this work provides a new approach for enhancing functionalities of artificial nanochannels by LbL supramolecular self-assemblies. Meanwhile, since the host molecule, CB[8], used in this work can interact with different kinds of biomolecules and stimuli-responsive chemical species, this work can be further extended to build a novel stable multiple-state research platform for a variety of uses such as sensing and controllable release.

Unusual synergistic effect in layered Ruddlesden−Popper oxide enables ultrafast hydrogen evolution
Publisher: Springer Science and Business Media LLC
Date: 11-01-2019
DOI: 10.1038/S41467-018-08117-6
Abstract: Efficient electrocatalysts for hydrogen evolution reaction are key to realize clean hydrogen production through water splitting. As an important family of functional materials, transition metal oxides are generally believed inactive towards hydrogen evolution reaction, although many of them show high activity for oxygen evolution reaction. Here we report the remarkable electrocatalytic activity for hydrogen evolution reaction of a layered metal oxide, Ruddlesden−Popper-type Sr 2 RuO 4 with alternative perovskite layer and rock-salt SrO layer, in an alkaline solution, which is comparable to those of the best electrocatalysts ever reported. By theoretical calculations, such excellent activity is attributed mainly to an unusual synergistic effect in the layered structure, whereby the (001) SrO-terminated surface cleaved in rock-salt layer facilitates a barrier-free water dissociation while the active apical oxygen site in perovskite layer promotes favorable hydrogen adsorption and evolution. Moreover, the activity of such layered oxide can be further improved by electrochemistry-induced activation.

High-Flux Ceramic Membranes with a Nanomesh of Metal Oxide Nanofibers
Publisher: American Chemical Society (ACS)
Date: 04-2008
DOI: 10.1021/JP709837R
Abstract: Traditional ceramic separation membranes, which are fabricated by applying colloidal suspensions of metal hydroxides to porous supports, tend to suffer from pinholes and cracks that seriously affect their quality. Other intrinsic problems for these membranes include dramatic losses of flux when the pore sizes are reduced to enhance selectivity and dead-end pores that make no contribution to filtration. In this work, we propose a new strategy for addressing these problems by constructing a hierarchically structured separation layer on a porous substrate using large titanate nanofibers and smaller boehmite nanofibers. The nanofibers are able to ide large voids into smaller ones without forming dead-end pores and with the minimum reduction of the total void volume. The separation layer of nanofibers has a porosity of over 70% of its volume, whereas the separation layer in conventional ceramic membranes has a porosity below 36% and inevitably includes dead-end pores that make no contribution to the flux. This radical change in membrane texture greatly enhances membrane performance. The resulting membranes were able to filter out 95.3% of 60-nm particles from a 0.01 wt % latex while maintaining a relatively high flux of between 800 and 1000 L/m2.h, under a low driving pressure (20 kPa). Such flow rates are orders of magnitude greater than those of conventional membranes with equal selectivity. Moreover, the flux was stable at approximately 800 L/m2.h with a selectivity of more than 95%, even after six repeated runs of filtration and calcination. Use of different supports, either porous glass or porous alumina, had no substantial effect on the performance of the membranes thus, it is possible to construct the membranes from a variety of supports without compromising functionality. The Darcy equation satisfactorily describes the correlation between the filtration flux and the structural parameters of the new membranes. The assembly of nanofiber meshes to combine high flux with excellent selectivity is an exciting new direction in membrane fabrication.

Single-phase perovskite oxide with super-exchange induced atomic-scale synergistic active centers enables ultrafast hydrogen evolution
Publisher: Springer Science and Business Media LLC
Date: 09-11-2020
DOI: 10.1038/S41467-020-19433-1
Abstract: The state-of-the-art active HER catalysts in acid media (e.g., Pt) generally lose considerable catalytic performance in alkaline media mainly due to the additional water dissociation step. To address this issue, synergistic hybrid catalysts are always designed by coupling them with metal (hydro)oxides. However, such hybrid systems usually suffer from long reaction path, high cost and complex preparation methods. Here, we discover a single-phase HER catalyst, SrTi 0.7 Ru 0.3 O 3-δ (STRO) perovskite oxide highlighted with an unusual super-exchange effect, which exhibits excellent HER performance in alkaline media via atomic-scale synergistic active centers. With insights from first-principles calculations, the intrinsically synergistic interplays between multiple active centers in STRO are uncovered to accurately catalyze different elementary steps of alkaline HER namely, the Ti sites facilitates nearly-barrierless water dissociation, Ru sites function favorably for OH* desorption, and non-metal oxygen sites (i.e., oxygen vacancies/lattice oxygen) promotes optimal H* adsorption and H 2 desorption.

Process considerations related to the microencapsulation of plasmid DNA via ultrasonic atomization
Publisher: Wiley
Date: 09-2008
DOI: 10.1002/BIT.21876
Abstract: An effective means of facilitating DNA vaccine delivery to antigen presenting cells is through biodegradable microspheres. Microspheres offer distinct advantages over other delivery technologies by providing release of DNA vaccine in its bioactive form in a controlled fashion. In this study, biodegradable poly(D,L-lactide-co-glycolide) (PLGA) microspheres containing polyethylenimine (PEI) condensed plasmid DNA (pDNA) were prepared using a 40 kHz ultrasonic atomization system. Process synthesis parameters, which are important to the scale-up of microspheres that are suitable for nasal delivery (i.e., less than 20 microm), were studied. These parameters include polymer concentration feed flowrate volumetric ratio of polymer and pDNA-PEI (plasmid DNA-polyethylenimine) complexes and nitrogen to phosphorous (N/P) ratio. PDNA encapsulation efficiencies were predominantly in the range 82-96%, and the mean sizes of the particle were between 6 and 15 microm. The ultrasonic synthesis method was shown to have excellent reproducibility. PEI affected morphology of the microspheres, as it induced the formation of porous particles that accelerate the release rate of pDNA. The PLGA microspheres displayed an in vitro release of pDNA of 95-99% within 30 days and demonstrated zero order release kinetics without an initial spike of pDNA. Agarose electrophoresis confirmed conservation of the supercoiled form of pDNA throughout the synthesis and in vitro release stages. It was concluded that ultrasonic atomization is an efficient technique to overcome the key obstacles in scaling-up the manufacture of encapsulated vaccine for clinical trials and ultimately, commercial applications.

Effect of seeding on formation of silicon carbide nanostructures from mesoporous silica-carbon nanocomposites
Publisher: IOP Publishing
Date: 25-03-2008
DOI: 10.1088/0957-4484/19/17/175605
Abstract: Mesoporous silica-carbon nanocomposites (C-SiO(2)) were synthesized for the fabrication of highly crystalline silicon carbide (SiC) nanoparticles and nanofibers via carbothermal reduction. SiC nuclei were introduced into the mesopores as seeds by infiltration of preceramic precursor polycarbosilane (PCS) prior to the heat treatment of carbothermal reduction. When PCS with a mass percentage of 11-13% was infiltrated into the mesoporous C-SiO(2), SiC nanofibers and nanoparticles were produced at 1450 °C, even in the s le with low carbon content. The major morphology formed from the mesoporous C-SiO(2) nanocomposites without PCS infiltration was nanoparticles, while nanofibers dominated in the products of PCS-infiltrated compositions. The results indicate that the conversion of PCS into SiC nuclei in mesopores prior to carbothermal reduction has facilitated the formation of SiC nanofibers. Therefore infiltration of seeds into mesopores of C-SiO(2) precursors appears to be an effective means of accelerating the reaction and controlling SiC nanostructures.

Alumina Hollow Fiber Supported ZIF-7 Membranes: Synthesis and Characterization
Publisher: American Scientific Publishers
Date: 02-2013
Abstract: ZIF-7 membrane has been prepared on the outer surface of alumina hollow fibers by the solvothermal synthesis. The synthesis conditions, including reaction temperature, time, and solution concentration, are investigated. At the reaction temperature of 100 degrees C for 8 h, microsized ZIF-7 crystals are grown on the outer surface of the hollow fibers. A continuous and dense ZIF-7 membrane with a thickness of about 5 microm is obtained after twice crystallization at 100 degrees C for 8 h. The gas separation test indicates the as-prepared ZIF-7 membranes have intercrystalline defects as the H2/N2 ideal selectivity is less than the Knudsen diffusion. After post-modification with beta-cyclodextrin aqueous solution, the micropore defects of ZIF-7 membrane is significantly reduced and the membrane has H2/N2 ideal selectivity of 3.9. The gas permeances for H2 and N2 are almost constant from room temperature to 150 degrees C for the ZIF-7 hollow fiber membranes before and after beta-cyclodextrin modification.

Here, we construct an artificial gate-location-tunable single-nanochannel system to systematically investigate the impact of the gate location on the ion transport property of the biomimetic ion channel. The gate-location-controllable single nanochannels are prepared by asymmetrically grafting pH-responsive polymer gates on one side of single nanochannels with gradual shape transformation. Experimental ion current measurements show that the gating abilities and rectification effects of the pH-gated nanochannels can be gradually altered by precisely locating the artificial pH gates on the different sites of the channels. The experimental gate-location-dependent gating and rectification of ion current in the bioinspired ion channel system is further well confirmed by theoretical simulation. This work, as an ex le, provides a new avenue to optimize the smart ion transport features of erse artificial nanogate devices via precisely locating the gates on the appropriate sites of the artificial nanochannels.
Aqueous Phase Synthesis of ZIF-8 Membrane with Controllable Location on an Asymmetrically Porous Polymer Substrate
Publisher: American Chemical Society (ACS)
Date: 26-02-2016
Abstract: In this study, we have demonstrated a simple, scalable, and environmentally friendly route for controllable fabrication of continuous, well-intergrown ZIF-8 on a flexible polymer substrate via contra-diffusion method in conjunction with chemical vapor modification of the polymer surface. The combined chemical vapor modification and contra-diffusion method resulted in controlled formation of a thin, defect-free, and robust ZIF-8 layer on one side of the support in aqueous solution at room temperature. The ZIF-8 membrane exhibited propylene permeance of 1.50 × 10(-8) mol m(-2) s(-1) Pa(-1) and excellent selective permeation properties after post heat-treatment, the membrane showed ideal selectivities of C3H6/C3H8 and H2/C3H8 as high as 27.8 and 2259, respectively. The new synthesis approach holds promise for further development of the fabrication of high-quality polymer-supported ZIF membranes for practical separation applications.

Fast deswelling of nanocomposite polymer hydrogels via magnetic field-induced heating for emerging FO desalination
Publisher: American Chemical Society (ACS)
Date: 29-05-2013
DOI: 10.1021/ES4005152
Abstract: Freshwater shortage is one of the most pressing global issues. Forward osmosis (FO) desalination technology is emerging for freshwater production from saline water, which is potentially more energy-efficient than the current reverse osmosis process. However, the lack of a suitable draw solute is the major hurdle for commercial implementation of the FO desalination technology. We have previously reported that thermoresponsive hydrogels can be used as the draw agent for a FO process, and this new hydrogel-driven FO process holds promise for further development for practical application. In the present work, magnetic field-induced heating is explored for the purpose of developing a more effective way to recover water from swollen hydrogel draw agents. The composite hydrogel particles are prepared by copolymerization of sodium acrylate and N-isopropylacrylamide in the presence of magnetic nanoparticles (γ-Fe2O3, <50 nm). The results indicate that the magnetic heating is an effective and rapid method for dewatering of hydrogels by generating the heat more uniformly throughout the draw agent particles, and thus, a dense skin layer commonly formed via conventional heating from the outside of the particle is minimized. The FO dewatering performance is affected by the loading of magnetic nanoparticles and magnetic field intensity. Significantly enhanced liquid water recovery (53%) is achieved under magnetic heating, as opposed to only around 7% liquid water recovery obtained via convection heating. Our study shows that the magnetic heating is an attractive alternative stimulus for the extraction of highly desirable liquid water from the draw agent in the polymer hydrogel-driven forward osmosis process.
Hydrogel-polyurethane interpenetrating network material as an advanced draw agent for forward osmosis process

DOI: 10.1016/J.WATRES.2016.03.072
Abstract: Water desalination and purification are critical to address the global issue of the shortage of clean water. Forward osmosis (FO) desalination is an emerging low-cost technology for clean water production from saline water. The lack of a suitable draw agent is one of hurdle for the commercialization of FO desalination technology. Recently, the thermoresponsive hydrogel has been demonstrated to be a potential draw agent for the FO process. However, the commonly used hydrogel powder shows a much lower flux than other kind of draw agent such as inorganic salts. In this work, a hydrogel-polyurethane interpenetrating network (HPIPN) with monolith form was prepared by controlling the radical polymerization of the monomers (N-isopropylacrylamide and sodium acrylate) in the macropores (∼400 μm) of commercial polyurethane foam (PUF). These HPIPN composites show a flux as high as 17.9 LMH, which is nearly 8 times than that of hydrogel powders (2.2 LMH). The high flux is attributed to the 3-D continuous hydrogel-polyurethane interpenetrating network, which can effectively enhance the water transport inside the monolith.
Synthesis of biodegradable polymer-mesoporous silica composite microspheres for DNA prime-protein boost vaccination
Publisher: Elsevier BV
Date: 03-2010
DOI: 10.1016/J.EJPS.2010.01.011
Abstract: DNA vaccines or proteins are capable of inducing specific immunity however, the translation to the clinic has generally been problematic, primarily due to the reduced magnitude of immune response and poor pharmacokinetics. Herein we demonstrate a composite microsphere formulation, composed of mesoporous silica spheres (MPS) and poly(D,L-lactide-co-glycolide) (PLGA), enables the controlled delivery of a prime-boost vaccine via the encapsulation of plasmid DNA (pDNA) and protein in different compartments. Method with modified dual-concentric-feeding needles attached to a 40 kHz ultrasonic atomizer was studied. These needles focus the flow of two different solutions, which passed through the ultrasonic atomizer. The process synthesis parameters, which are important to the scale-up of composite microspheres, were also studied. These parameters include polymer concentration, feed flowrate, and volumetric ratio of polymer and pDNA-PEI/MPS-BSA. This fabrication technique produced composite microspheres with mean D[4,3] ranging from 6 to 34 microm, depending upon the microsphere preparation. The resultant physical morphology of composite microspheres was largely influenced by the volumetric ratio of pDNA-PEI/MPS-BSA to polymer, and this was due to the precipitation of MPS at the surface of the microspheres. The encapsulation efficiencies were predominantly in the range of 93-98% for pDNA and 46-68% for MPS. In the in vitro studies, the pDNA and protein showed different release kinetics in a 40 day time frame. The dual-concentric-feeding in ultrasonic atomization was shown to have excellent reproducibility. It was concluded that this fabrication technique is an effective method to prepare formulations containing a heterologous prime-boost vaccine in a single delivery system.
Do highly physically active workers die early? A systematic review with meta-analysis of data from 193 696 participants

DOI: 10.1136/BJSPORTS-2017-098540
Abstract: Recent evidence suggests the existence of a physical activity paradox, with beneficial health outcomes associated with leisure time physical activity, but detrimental health outcomes for those engaging in high level occupational physical activity. This is the first quantitative systematic review of evidence regarding the association between occupational physical activity and all-cause mortality. Systematic review with meta-analysis. A literature search was performed in electronic databases PubMed, Embase, CINAHL, PsycINFO and Cochrane. We screened for peer reviewed articles from prospective studies assessing the association of occupational physical activity with all-cause mortality. A meta-analysis assessed the association of high (compared with low) level occupational physical activity with all-cause mortality, estimating pooled hazard ratios (HR) (with 95% CI). 2490 unique articles were screened and 33 (from 26 studies) were included. Data from 17 studies (with 193 696 participants) were used in a meta-analysis, showing that men with high level occupational physical activity had an 18% increased risk of early mortality compared with those engaging in low level occupational physical activity (HR 1.18, 95% CI 1.05 to 1.34). No such association was observed among women, for whom instead a tendency for an inverse association was found (HR 0.90, 95% CI 0.80 to 1.01). The results of this review indicate detrimental health consequences associated with high level occupational physical activity in men, even when adjusting for relevant factors (such as leisure time physical activity). These findings suggest that research and physical activity guidelines may differentiate between occupational and leisure time physical activity.
Nanoarchitectonics for Electrospun Membranes with Asymmetric Wettability
Publisher: American Chemical Society (ACS)
Date: 16-12-2021
Abstract: Membranes with asymmetric wettability have attracted significant interest by virtue of their unique transport characteristics and functionalities arising from different wetting behaviors of each membrane surface. The cross-sectional wettability distinction enables a membrane to realize directional liquid transport or multifunction integration, resulting in rapid advance in applications, such as moisture management, fog collection, oil-water separation, and membrane distillation. Compared with traditional homogeneous membranes, these membranes possess enhanced transport performance and higher separation efficiency owing to the synergistic or in idual effects of asymmetric wettability. This Review covers the recent progress in fabrication, transport mechanisms, and applications of electrospun membranes with asymmetric wettability and provides a perspective on future development in this important area.

Surface Patterned Porous Films by Convection-Assisted Dynamic Self-Assembly of Zeolite Nanoparticles
Publisher: American Chemical Society (ACS)
Date: 03-04-2001
DOI: 10.1021/LA0102509
Abstract: This study demonstrates for the first time that porous zeolite films with surface patterns such as knotted-rope web and wrinkled honeycomb can be obtained by convection-assisted dynamic self-assembly of zeolite nanoparticles. The study also shows that an appropriate dispersant and the presence of zeolite nanoparticles with a specific range of particle sizes in the colloidal suspension are critical for pattern formation. The patterned zeolite films have a well-defined bimodal pore size distribution (i.e., 0.55 and 2.6 nm) with a high Brunauer-Emmett-Teller surface area of 680-750 m(2)/g and are attractive for potential applications in fields such as thin film catalysis, adsorption separation, chemical sensor arrays, and components in microelectronic devices.

Zeolitic Imidazolate Framework/Graphene Oxide Hybrid Nanosheets as Seeds for the Growth of Ultrathin Molecular Sieving Membranes
Publisher: Wiley
Date: 28-12-2016
Abstract: A defect-free zeolitic imidazolate framework-8 (ZIF-8)/graphene oxide (GO) membrane with a thickness of 100 nm was prepared using two-dimensional (2D) ZIF-8/GO hybrid nanosheets as seeds. Hybrid nanosheets with a suitable amount of ZIF-8 nanocrystals were essential for producing a uniform seeding layer that facilitates fast crystal intergrowth during membrane formation. Moreover, the seeding layer acts as a barrier between two different synthesis solutions, and self-limits crystal growth and effectively eliminates defects during the contra-diffusion process. The resulting ultrathin membranes show excellent molecular sieving gas separation properties, such as with a high CO2 /N2 selectivity of 7.0. This 2D nano-hybrid seeding strategy can be readily extended to the fabrication of other defect-free and ultrathin MOF or zeolite molecular sieving membranes for a wide range of separation applications.

Bifunctional Polymer Hydrogel Layers As Forward Osmosis Draw Agents for Continuous Production of Fresh Water Using Solar Energy
Publisher: American Chemical Society (ACS)
Date: 04-11-2013
DOI: 10.1021/ES403266Y
Abstract: The feasibility of bilayer polymer hydrogels as draw agent in forward osmosis process has been investigated. The dual-functionality hydrogels consist of a water-absorptive layer (particles of a copolymer of sodium acrylate and N-isopropylacrylamide) to provide osmotic pressure, and a dewatering layer (particles of N-isopropylacrylamide) to allow the ready release of the water absorbed during the FO drawing process at lower critical solution temperature (32 °C). The use of solar concentrated energy as the source of heat resulted in a significant increase in the dewatering rate as the temperature of dewatering layer increased to its LSCT more rapidly. Dewatering flux rose from 10 to 25 LMH when the solar concentrator increased the input energy from 0.5 to 2 kW/m(2). Thermodynamic analysis was also performed to find out the minimum energy requirement of such a bilayer hydrogel-driven FO process. This study represents a significant step forward toward the commercial implementation of hydrogel-driven FO system for continuous production of fresh water from saline water or wastewaters.

Scalable high yield exfoliation for monolayer nanosheets
Publisher: Springer Science and Business Media LLC

DOI: 10.1038/S41467-022-35569-8
Abstract: Although two-dimensional (2D) materials have grown into an extended family that accommodates hundreds of members and have demonstrated promising advantages in many fields, their practical applications are still hindered by the lack of scalable high-yield production of monolayer products. Here, we show that scalable production of monolayer nanosheets can be achieved by a facile ball-milling exfoliation method with the assistance of viscous polyethyleneimine (PEI) liquid. As a demonstration, graphite is effectively exfoliated into graphene nanosheets, achieving a high monolayer percentage of 97.9% at a yield of 78.3%. The universality of this technique is also proven by successfully exfoliating other types of representative layered materials with different structures, such as carbon nitride, covalent organic framework, zeolitic imidazolate framework and hexagonal boron nitride. This scalable exfoliation technique for monolayer nanosheets could catalyze the synthesis and industrialization of 2D nanosheet materials.

Voltage-Gated Ion Transport in Two-Dimensional Sub-1 nm Nanofluidic Channels
Publisher: American Chemical Society (ACS)
Date: 17-09-2019
Abstract: Voltage-gated nanofluidic systems have shown a wide range of potential applications in biosensors, energy harvest, and separation. Two-dimensional (2D) nanofluidic membranes fabricated with electrically conductive nanosheets have high ion conductivity and voltage-gated ion transport behaviors. However, the voltage-gating effect of the sub-nanometer-sized 2D channel membranes has not been well-investigated. In this work, a high-performance voltage-gated 2D nanofluidic device is constructed by assembling MXene nanosheets into a laminar membrane with sub-1 nm interlayer channels. By applying external voltage to the membrane, the ion conductivity of the device is enhanced by positive voltages and reduced by negative voltages, exhibiting a high voltage-gating on-off ratio of ∼10. The on-off ratio is found to be dependent on ion concentration and ion species. This work demonstrates that 2D membranes with interlayer spacings comparable to those of hydrated ion diameters can achieve high and tunable voltage-gating function, which provides a strategy to construct devices for highly efficient on-demand ion transport.
A Homochiral Poly(2‐oxazoline)‐based Membrane for Efficient Enantioselective Separation
Publisher: Wiley
Date: 18-01-2023
Abstract: Chiral separation membranes have shown great potential for the efficient separation of racemic mixtures into enantiopure components for many applications, such as in the food and pharmaceutical industries however, scalable fabrication of membranes with both high enantioselectivity and flux remains a challenge. Herein, enantiopure S ‐poly(2,4‐dimethyl‐2‐oxazoline) ( S ‐PdMeOx) macromonomers were synthesized and used to prepare a new type of enantioselective membrane consisting of a chiral S ‐PdMeOx network scaffolded by graphene oxide (GO) nanosheets. The S ‐PdMeOx‐based membrane showed a near‐quantitative enantiomeric excess ( ee ) (98.3±1.7 %) of S ‐(−)‐limonene over R ‐(+)‐limonene and a flux of 0.32 mmol m −2 h −1 . This work demonstrates the potential of homochiral poly(2,4‐disubstituted‐2‐oxazoline)s in chiral discrimination and provides a new route to the development of highly efficient enantioselective membranes using synthetic homochiral polymer networks.

Lithium Extraction by Emerging Metal–Organic Framework‐Based Membranes
Publisher: Wiley
Date: 07-08-2021
Abstract: Lithium is mainly extracted from brine and ores however, current lithium mining methods require large amounts of chemicals, discharge many wastes, and can have serious environmental repercussions. Metal–organic framework (MOF)‐based membranes have shown great potential in lithium extraction due to their uniform pore sizes, high porosities, and rich host–guest chemistry compared to other materials. In this review, the processes and disadvantages of current lithium extraction technologies are introduced. The structure features and corresponding design strategy of MOFs suitable for Li + ion separations are presented. Following, recent advances of polycrystalline MOF membranes, mixed matrix membranes, and MOF channel membranes for lithium‐ion separation are discussed in detail. Finally, opportunities for future developments and challenges in this emerging research field are presented.

Rapid Construction of ZnO@ZIF-8 Heterostructures with Size-Selective Photocatalysis Properties
Publisher: American Chemical Society (ACS)
Date: 29-03-2016
Abstract: To selectively remove heavy metal from dye solution, inspired by the unique pore structure of ZIF-8, we developed a synthetic strategy for rapid construction of ZnO@ZIF-8 heterostructure photocatalyst for selective reduction of Cr(VI) between Cr(VI) and methylene blue (MB). In particular, ZnO@ZIF-8 core-shell heterostructures were prepared by in situ ZIF-8 crystal growth using ZnO colloidal spheres as template and zinc source within 8-60 min. The shell of the resulting ZnO@ZIF-8 core-shell heterostructure with a uniform thickness of around 30 nm is composed of ZIF-8 crystal polyhedrons. The concentration of organic ligand 2-methylimidazole (Hmim) was found to be crucial for the formation of ZnO@ZIF-8 core-shell heterostructures. Different structures, ZnO@ZIF-8 core-shell spheres and separate ZIF-8 polyhedrons could be formed by altering Hmim concentration, which significantly influences the balance between rate of Zn(2+) release from ZnO and coordinate rate. Importantly, such ZnO@ZIF-8 core-shell heterostructures exhibit size-selective photocatalysis properties due to selective adsorption and permeation effect of ZIF-8 shell. The as-synthesized ZnO@ZIF-8 heterostructures exhibited enhanced selective reduction of Cr(VI) between Cr(VI) and MB, which may find application in the dye industry. This work not only provides a general route for rapid fabrication of such core-shell heterostructures but also illustrates a strategy for selectively enhanced photocatalysis performance by utilizing adsorption and size selectivity of ZIF-8 shell.
