Can the use of quality assurance tools reduce the impact of surgical complications on the well-being of obstetricians and gynaecologists in Australia and New Zealand?
Publisher: Wiley

DOI: 10.1111/AJO.12162
Abstract: While adverse events primarily affect the patient, surgeons involved can also experience considerable distress. The aim of the survey was to assess the impact of complications on the day-to-day life, work and health of Australian and New Zealand obstetricians and gynaecologists and to evaluate existing support systems and coping strategies. A 43-question survey on self-assessment, quality assurance (QA) tools, impact of complications on in iduals' health and relationships, and support available was emailed to fellows, trainees, subspecialists and subspecialty trainees of the Royal Australian and New Zealand College of Obstetrics and Gynaecology (RANZCOG). We collected 606 responses from a target population of 2296 (response rate 26.3%). When complications occur, sleep was affected of 80%, family and social relationships of 55% and physical health of 48% of respondents. The major sources of support were from colleagues (83%), family (82%) and medical defence organisations (73%), with professional bodies perceived as providing least support. Nearly 80% of respondents felt the need to talk to someone they trust during times of complications. Overall, 100% of respondents used at least one QA tool (62% used two, 26% three and 9% four QA strategies). There were significant differences between respondent groups in use of the QA tools. Surgical complications have a significant impact on the well-being of Australian and New Zealand obstetricians and gynaecologists. Existing support comes from colleagues and family, but structured, unbiased support for surgeons from a professional source is urgently warranted.

Hierarchical Nanostructures of Nitrogen-Doped Porous Carbon Polyhedrons Confined in Carbon Nanosheets for High-Performance Supercapacitors
Publisher: American Chemical Society (ACS)
Date: 24-05-2018
Abstract: Interconnected close-packed nitrogen-doped porous carbon polyhedrons (NCPs) confined in two-dimensional carbon nanosheets (CNSs) have been prepared through a sustainable one-pot pyrolysis of a simple solid mixture of zeolitic imidazolate framework-8 (ZIF-8) crystals and with organic potassium as the precursors. The hierarchically organized framework of the NCP-CNS composites enables NCPs and CNSs to act as well-defined electrolyte reservoirs and mechanical buffers accommodating large volume expansions of NCPs, respectively. Among the unique composite nanostructures, the NCPs with vast micropores provide electric double-layer capacitances, while the CNSs bridge the in idual NCPs to form a conductive pathway with a hierarchical porosity. As a result, the NCP-CNS composites with high electrical integrity and structural stability are used as electrode materials for high-performance supercapacitors, which exhibit excellent electrochemical capacitive characteristics in terms of an outstanding capacitance of 300 F g

Integrating a Metal–Organic Framework into Natural Spruce Wood for Efficient Solar‐Powered Water Evaporation
Publisher: Wiley
Date: 13-07-2022
Abstract: With the increase in water consumption and pollution resulting from the rising world population and industrial development, severe fresh water shortage has been regarded as one of the critical problems facing the world. Solar‐driven water purification is an environment friendly and promising technology to address the problem. However, low photothermal conversion efficiency impedes its practical application. Herein, a natural spruce wood‐based solar evaporator functionalized with zeolitic imidazolate framework (ZIF‐8) nanoparticles and polydopamine (PDA) layers is designed, which significantly reduces the equivalent evaporation enthalpy and substantially boosts solar evaporation efficiency. The evaporation rate of the optimized wood‐based evaporator reached 2.28 kg m −2 h −1 with a high evaporation efficiency of 87.5% under 1.0 sun. Furthermore, the integrated spruce wood/ZIF‐8/PDA hybrids can remove organic pollutants after solar evaporation. Notably, the constructed multifunctional solar evaporator takes advantage of sustainable solar energy, low‐cost biomass, and ZIF‐8/PDA nanostructures to acquire desirable performance in water evaporation and sewage purification.

Cryopolymerization enables anisotropic polyaniline hybrid hydrogels with superelasticity and highly deformation-tolerant electrochemical energy storage

DOI: 10.1038/S41467-019-13959-9
Abstract: The development of energy storage devices that can endure large and complex deformations is central to emerging wearable electronics. Hydrogels made from conducting polymers give rise to a promising integration of high conductivity and versatility in processing. However, the emergence of conducting polymer hydrogels with a desirable network structure cannot be readily achieved using conventional polymerization methods. Here we present a cryopolymerization strategy for preparing an intrinsically stretchable, compressible and bendable anisotropic polyvinyl alcohol olyaniline hydrogel with a complete recovery of 100% stretching strain, 50% compressing strain and fully bending. Due to its high mechanical strength, superelastic properties and bi-continuous phase structure, the as-obtained anisotropic polyvinyl alcohol olyaniline hydrogel can work as a stretching/compressing/bending electrode, maintaining its stable output under complex deformations for an all-solid-state supercapacitor. In particular, it achieves an extremely high energy density of 27.5 W h kg −1 , which is among that of state-of-the-art stretchable supercapacitors.

Upconversion-Agent Induced Improvement of g-C3N4 Photocatalyst under Visible Light
Publisher: American Chemical Society (ACS)
Date: 23-09-2014
DOI: 10.1021/AM5051263
Abstract: Herein, we report the use of upconversion agents to modify graphite carbon nitride (g-C3N4) by direct thermal condensation of a mixture of ErCl3·6H2O and the supramolecular precursor cyanuric acid-melamine. We show the enhancement of g-C3N4 photoactivity after Er(3+) doping by monitoring the photodegradation of Rhodamine B dye under visible light. The contribution of the upconversion agent is demonstrated by measurements using only a red laser. The Er(3+) doping alters both the electronic and the chemical properties of g-C3N4. The Er(3+) doping reduces emission intensity and lifetime, indicating the formation of new, nonradiative deactivation pathways, probably involving charge-transfer processes.

Phenyl‐Modified Carbon Nitride Quantum Dots with Distinct Photoluminescence Behavior
Publisher: Wiley
Date: 16-02-2016
Abstract: A novel type of quantum dot (Ph-CN) is manufactured from graphitic carbon nitride by "lining" the carbon nitride structure with phenyl groups through supramolecular preorganization. This approach requires no chemical etching or hydrothermal treatments like other competing nanoparticle syntheses and is easy and safe to use. The Ph-CN nanoparticles exhibit bright, tunable fluorescence, with a high quantum yield of 48.4 % in aqueous colloidal suspensions. Interestingly, the observed Stokes shift of approximately 200 nm is higher than the maximum values reported for carbon nitride based fluorophores. The high quantum yield and the large Stokes shift are related to the structural surface organization of the phenyl groups, which affects the π-electron delocalization in the conjugated carbon nitride networks and induces colloidal stability. The remarkable performance of the Ph-CN nanoparticles in imaging is demonstrated by a simple incubation study with HeLa cells.

Hybridizing Carbon Nitride Colloids with a Shell of Water-Soluble Conjugated Polymers for Tunable Full-Color Emission and Synergistic Cell Imaging.
Publisher: American Chemical Society (ACS)
Date: 07-12-2017
Abstract: We present the preparation of a new multicolor emission system constructed from two complementary conjugated materials that are highly photoluminescent, that is, phenyl-modified carbon nitride (PhCN) colloids as the core and water-soluble conjugated polymers (WSCPs) adsorbed as the shell. The fluorescence bands of the PhCN and WSCPs effectively complement each other and the overall emission can be simply adjusted to fully cover the visible light spectrum with white light emission also accessible. Photophysical insights imply that the interactions between PhCN and WSCPs preserve the binary system from emission distortion and degradation, which is essential to delicately tune the overall fluorescence bands. Notably, the continuously tunable emission color is achieved under single-wavelength excitation (365 nm). This hybrid shows a synergistic permeation performance in cell imaging, that is, PhCN nanoparticles help the WSCP to enter the cells and therefore multicolor cellular imaging achieved.

Step-by-step mechanism insights into TiO2/Ce2S3 S-scheme photocatalyst for enhanced aniline production with water as proton source
Publisher: Research Square Platform LLC
Date: 10-09-2021
DOI: 10.21203/RS.3.RS-876600/V1
Abstract: Exploring new heterostructured photocatalysts for photocatalytic hydrogenation reaction with water as proton source and investigating the corresponding intrinsic step-by-step mechanism are of great interests. Here we develop a novel S-scheme heterojunction through theoretical design and implemented by solvothermal growth of Ce 2 S 3 nanoparticles onto electrospun TiO 2 nanofibers. The low-dimensional (0D/1D) heterostructure unveils enhanced photocatalytic activity for aniline production by nitrobenzene hydrogenation with water as proton source. Density functional theory (DFT) calculations indicate the electrons transfer from Ce 2 S 3 to TiO 2 upon hybridization due to their Fermi level difference and creates an internal electric field at the interface, driving the efficient separation of the photoexcited charge carriers, which is authenticated by in-situ X-ray photoelectron spectroscopy along with femtosecond transient absorption spectroscopy. The step-by-step reaction mechanism of the photocatalytic nitrobenzene hydrogenation to yield aniline is revealed by in-situ diffuse reflectance infrared Fourier transform spectroscopy, associated with DFT computational prediction.

Abstract: In this work, we report on the synthesis of a free-standing, macroscopic robust supramolecular membrane by introducing silver-nitrogen coordinate bonding into preorganized, supramolecular hydrogen-bonded cyanuric acid-melamine (CAM) crystals. With the assistance of ammonia, silver ions competitively replace two of the three hydrogen atoms from cyanuric acid resulting in the transformation from short CAM nanorods to long CAM-Ag nanofibers (length over 1000 μm), accompanied by tautomerization of cyanuric acid. The single crystal structure of the CAM-Ag nanofibers is solved in the space group

Silver Phosphate/Graphitic Carbon Nitride as an Efficient Photocatalytic Tandem System for Oxygen Evolution
Publisher: Wiley
Date: 18-02-2015
Abstract: Herein, we show the facile synthesis of an efficient silver phosphate/graphitic carbon nitride (Ag3 PO4 /g-C3 N4 ) photocatalyst for oxygen production and pollutant degradation by using electrostatically driven assembly and ion-exchange processes. The composite materials demonstrate a sheet-like C3 N4 structure, decorated with different Ag3 PO4 particles sizes. Detailed analysis of the reactions mechanism by electron-spin resonance and radical-capture agents strongly imply the formation of an in situ Z-scheme by the evolution of small silver nanoparticles in the interface of the materials under illumination. The Ag nanoparticles improve charge separation within the composite material by acting as a storage and recombination center for electrons and holes from Ag3 PO4 and C3 N4 , respectively. In addition, the photostability of Ag3 PO4 is enhanced relative to that of the bulk materials, which results in a stabilized heterojunction. We believe that this work provides new insight into the operation mechanism of composite photocatalysts for water splitting and opens the possibility for advanced photocatalysis based on the higher oxidation power of Ag3 PO4 .

Unique S-scheme heterojunctions in self-assembled TiO2/CsPbBr3 hybrids for CO2 photoreduction
Publisher: Springer Science and Business Media LLC

DOI: 10.1038/S41467-020-18350-7
Abstract: Exploring photocatalysts to promote CO 2 photoreduction into solar fuels is of great significance. We develop TiO 2 erovskite (CsPbBr 3 ) S-scheme heterojunctions synthesized by a facile electrostatic-driven self-assembling approach. Density functional theory calculation combined with experimental studies proves the electron transfer from CsPbBr 3 quantum dots (QDs) to TiO 2 , resulting in the construction of internal electric field (IEF) directing from CsPbBr 3 to TiO 2 upon hybridization. The IEF drives the photoexcited electrons in TiO 2 to CsPbBr 3 upon light irradiation as revealed by in-situ X-ray photoelectron spectroscopy analysis, suggesting the formation of an S-scheme heterojunction in the TiO 2 /CsPbBr 3 nanohybrids which greatly promotes the separation of electron-hole pairs to foster efficient CO 2 photoreduction. The hybrid nanofibers unveil a higher CO 2 -reduction rate (9.02 μmol g –1 h –1 ) comparing with pristine TiO 2 nanofibers (4.68 μmol g –1 h –1 ). Isotope ( 13 CO 2 ) tracer results confirm that the reduction products originate from CO 2 source.

Abstract: Solar-driven water oxidation is the key step for overall water splitting that efficiently harvests and converts solar energy into fuels the development of a highly efficient photocatalyst that can mediate water oxidation has become an appealing challenge. Herein, we report a facile two-step process to decorate silver phosphate (Ag3PO4) particles on different types of graphitic carbon nitrides (g-C3N4) as composite photocatalysts for water oxidation. For all the Ag3PO4/g-C3N4 materials, an in situ Z-scheme is created by the generation of Ag nanoparticles which act as a cross-linking bridge between Ag3PO4 and g-C3N4 in the composite, resulting in better charge separation and higher catalytic performance. A detailed analysis emphasizes the importance of the g-C3N4 on the chemical, photophysical, and catalytic properties of the composite materials. Our results show that the alteration of the morphology dominates the performance of the composite materials.

Cobalt, Nitrogen-Doped Porous Carbon Nanosheet-Assembled Flowers from Metal-Coordinated Covalent Organic Polymers for Efficient Oxygen Reduction
Publisher: American Chemical Society (ACS)
Date: 12-12-2018
Abstract: The breakthrough of nonprecious metal catalysts replacing platinum-based catalysts toward the oxygen reduction reaction (ORR) is extremely urgent for the development of high-efficiency energy conversation systems. Herein, a solution-processed condensation polymerization using cyanuric chloride and piperazine as the monomers was proposed for the synthesis of a nitrogen-rich covalent organic polymer (COP). High contents of precisely tailored pyridinic-N within the COP facilitate the formation of the Co/N coordination between Co ions and N species. As a result, the subsequent carbonization of the Co-coordinated COP led to the formation of the cobalt, nitrogen dual-doped porous carbon nanosheet-assembled flowers (Co/N-PCNF). The as-obtained Co/N-PCNF catalyst with a nearly 4-electron oxygen reduction pathway exhibits an excellent ORR catalytic activity with a half-wave potential of 0.835 V comparable to the commercial Pt/C catalysts (0.865 V). Most impressively, the Co/N-PCNF catalyst displays a long-term stability and a much better resistance to methanol than the Pt/C catalyst because of its high surface area, well-defined porous structure, and homogeneous distributions of active sites within the carbon matrix. Therefore, this work establishes an operating rule for tailored synthesis of COP-derived nonprecious metal catalysts offering high activity for the ORR in electrochemical energy conversations.

Electrophoretic Deposition of Carbon Nitride Layers for Photoelectrochemical Applications
Publisher: American Chemical Society (ACS)
Date: 11-05-2016
Abstract: Electrophoretic deposition (EPD) is used for the growth of carbon nitride (C3N4) layers on conductive substrates. EPD is fast, environmentally friendly, and allows the deposition of negatively charged C3N4 with different compositions and chemical properties. In this method, C3N4 can be deposited on various conductive substrates ranging from conductive glass and carbon paper to nickel foam possessing complex 3D geometries. The high flexibility of this approach enables us to readily tune the photophysical and photoelectronic properties of the C3N4 electrodes. The advantage of this method was further illustrated by the tailored construction of a heterostructure between two complementary C3N4, with marked photoelectrochemical activity.

Abstract: Monodisperse Fe(3)O(4) and γ-Fe(2)O(3) magnetic mesoporous microspheres are prepared via a surfactant-free solvothermal combined with precursor thermal transformation method. The as-prepared Fe(3)O(4) and γ-Fe(2)O(3) magnetic mesoporous microspheres have a relatively high specific surface area of 122.3 and 138.6 m(2)/g, respectively. The Fe(3)O(4) and γ-Fe(2)O(3) magnetic mesoporous microspheres are explored as the anode materials for lithium-ion batteries, and they have a high initial discharge capacity of 1307 and 1453 mA h/g, respectively, and a good reversible performance (450 mA h/g for Fe(3)O(4) and 697 mA h/g for γ-Fe(2)O(3) after 110 cycles) at the current density of 0.2C.
