Influence of Film Stability and Aging of Plasma Polymerized Allylamine Coated Quartz Particles on Humic Acid Removal
Publisher: American Chemical Society (ACS)
Date: 19-07-2013
DOI: 10.1021/AM401648G
Abstract: Plasma polymerized allylamine (ppAA) films have been successfully deposited on to the surface of quartz particles via a rotating barrel plasma reactor for humic acid removal. The films were deposited at a power of 25 W, allylamine flow rate of 4.4 sccm and polymerization times of 5 to 60 min. X-ray photoelectron spectroscopy was used to investigate the influence of short-term stirring in water and film age on surface chemistry. Stirring results in a reduction in the nitrogen concentration, which was greatest for shorter polymerization times. Film aging of up to 52 weeks appeared to result in a reduction in the concentration of C-N species. The influence of batch, recycling, and film age on humic acid removal was investigated. Humic acid removal appeared to be reproducible across three separate batches for polymerization times of 20 min or more, which was attributed to film thickness. Recycling of the ppAA films was most successful at pH 11 for up to 4 humic acid removal/regeneration cycles. Successful regeneration at pH 11 was attributed to electrostatic repulsion of the adsorbed humic acid molecules. Decreasing the pH of the regeneration solution reduced the number of successful regeneration cycles due to greater retention of adsorbed humic acid via electrostatic attraction. Film age appears to have minimal effect on humic acid removal where freshly deposited and 52-week-old films removed similar masses of humic acid. Successful production and development of ppAA coated quartz particles has resulted in a functional material that can be incorporated into a water treatment system to improve water quality.

Interaction of functionalised surfaces on silica with dissolved metal cations in aqueous solutions
Publisher: Walter de Gruyter GmbH
Date: 06-2006
DOI: 10.3139/146.101303
Abstract: The study clearly shows that different metal cations were efficiently removed from water by employing coated silica particles with SO 3 H-terminated functionalized surfaces. Significant amounts of Fe, Mn, Ca, Mg, Na, and K could be removed from natural water s les with different concentrations varying from 0.075mg/l for Mn up to 12000mg/l for Na by stirring the functionalized silica particles in the water s les for 1h at room temperature. ICP–MS verify the removal of the elements and ToF-SIMS analyses clearly showed the presence of the elements on the particles after the treatment procedure. The removal of the metal cations is believed to be due to electrostatic attraction of the positively charged presumably hydrolysed metal cations to the negatively charged deprotonated SO 3 H-groups. However, from the current study it can not be excluded that chemisorption of the cations by the SO 3 H-group may be possible.

Dwarf AGNs from Optical Variability for the Origins of Seeds (DAVOS): insights from the dark energy survey deep fields
Publisher: Oxford University Press (OUP)
Date: 13-08-2022
Abstract: We present a s le of 706, z & 1.5 active galactic nuclei (AGNs) selected from optical photometric variability in three of the Dark Energy Survey (DES) deep fields (E2, C3, and X3) over an area of 4.64 deg2. We construct light curves using difference imaging aperture photometry for resolved sources and non-difference imaging PSF photometry for unresolved sources, respectively, and characterize the variability significance. Our DES light curves have a mean cadence of 7 d, a 6-yr baseline, and a single-epoch imaging depth of up to g ∼ 24.5. Using spectral energy distribution (SED) fitting, we find 26 out of total 706 variable galaxies are consistent with dwarf galaxies with a reliable stellar mass estimate ($M_{\\ast }\\lt 10^{9.5}\\, {\\rm M}_\\odot$ median photometric redshift of 0.9). We were able to constrain rapid characteristic variability time-scales (∼ weeks) using the DES light curves in 15 dwarf AGN candidates (a subset of our variable AGN candidates) at a median photometric redshift of 0.4. This rapid variability is consistent with their low black hole (BH) masses. We confirm the low-mass AGN nature of one source with a high S/N optical spectrum. We publish our catalogue, optical light curves, and supplementary data, such as X-ray properties and optical spectra, when available. We measure a variable AGN fraction versus stellar mass and compare to results from a forward model. This work demonstrates the feasibility of optical variability to identify AGNs with lower BH masses in deep fields, which may be more ‘pristine’ analogues of supermassive BH seeds.

A holistic reverse logistics planning framework for end-of-life PV panel collection system design
Publisher: Elsevier BV
Date: 09-2022
DOI: 10.1016/J.JENVMAN.2022.115331
Abstract: Photovoltaic (PV) technologies are critical for sustainable energy supply, climate change mitigation, and energy security with lower environmental impact compared to other generation alternatives. Despite the environmental benefits of PV technologies, one of these major downsides is the growing concern over the environmental impact due to risks associated with improper waste handling and disposal of decommissioned PV panels. As a result, there are strong incentives for PV panel recycling to recover valuable resources and mitigate risks caused by hazardous substances. This study proposes a reverse logistical planning framework for collecting end-of-life PV panels, which aims to support the integration of existing recycling technologies and collection schemes using a holistic approach for ensuring feasibility and reducing environmental impact. The framework reviews current recycling methodologies for PV waste and the state of PV markets, including PV uptake, waste stream forecast, collection and logistic strategies. Additionally, South Australia is used as the context of analysis for a case study where the framework is applied to identify the potential strategies for handling and collection of end-of-life PV panels based on current PV uptake and waste stream forecast. As a result, capital, transportation and operation costs can be reduced, contributing to lower overall recycling cost for the PV waste treatment and a more efficient reverse logistic system.

Hydrolytic Stability of Mesoporous Zirconium Titanate Frameworks Containing Coordinating Organic Functionalities
Publisher: American Chemical Society (ACS)
Date: 06-05-2013
DOI: 10.1021/AM3031695
Abstract: The hydrolytic stability of lanthanide and actinide selective mono- and polyphosphonate-functionalized mesoporous zirconium titanium oxide adsorbents has been investigated in nitric acid solutions. Hydrolytic degradation of the surfaces, as measured through the fractional loss of phosphorus and elements of the oxide framework, increased by more than an order of magnitude as the nitric acid concentration was increased from 0 to 2 mol/L. The unfunctionalized parent oxide suffered considerable dissolution in 2 mol/L acid over a period of 72 h. Under identical conditions, the fractional Zr and Ti release was reduced to 1 × 10(-2) for monophosphonate functionalized hybrids and reached as low as 1 × 10(-6) for trisphosphonate functionalized variants. The bisphosphonates showed intermediate values. The leaching of P, Zr and Ti was found to be incongruent with the Zr leaching to a lesser extent implying enhanced stability of the Zr-O-P bond. Quantitative analysis of the dissolution kinetics indicated a parabolic dissolution model with a rate constant in the range of 0.5-1.5 mg g(-1) min(-1/2) for the elemental leaching of P, Ti, and Zr. The leaching of Zr from the mesoporous matrix was relatively more complex than for the other elements with evidence of a leaching mechanism involving two processes. ToF-SIMS and DRIFT analysis demonstrated that after leaching in 2 M HNO3 for 24 h, a significant proportion of grafted ligands remained on the surface. The oxide functionalized with amino trismethylenephosphonic acid, which had previously shown excellent (153)Gd(3+) selectivity, was demonstrated to have outstanding stability, with low fractional elemental losses and preservation of mesoporous texture even after leaching for 24 h in 2 M HNO3. This suggests this particular hybrid to be worthy of additional study.

Fundamental physics with the Square Kilometre Array
Publisher: Cambridge University Press (CUP)

DOI: 10.1017/PASA.2019.42
Abstract: The Square Kilometre Array (SKA) is a planned large radio interferometer designed to operate over a wide range of frequencies, and with an order of magnitude greater sensitivity and survey speed than any current radio telescope. The SKA will address many important topics in astronomy, ranging from planet formation to distant galaxies. However, in this work, we consider the perspective of the SKA as a facility for studying physics. We review four areas in which the SKA is expected to make major contributions to our understanding of fundamental physics: cosmic dawn and reionisation gravity and gravitational radiation cosmology and dark energy and dark matter and astroparticle physics. These discussions demonstrate that the SKA will be a spectacular physics machine, which will provide many new breakthroughs and novel insights on matter, energy, and spacetime.

Abstract: Superconducting bulk ceramics in the form of rods, tubes, rings or blocks are best produced from the 2212 phase of the title system. Until now, however, the 2212 single‐phase region, which also involves regions of varying Sr/Ca ratio and varying Bi contents, has not been unambiguously characterized. In this work, the 2212 single‐phase region is defined and the critical temperature ( T c ) correlated with the chemical composition.

Product stewardship considerations for solar photovoltaic panels
Publisher: American Institute of Mathematical Sciences (AIMS)
Date: 2023
Abstract: abstract While the uptake of solar photovoltaic panels for the generation of clean energy has almost exponentially increased over the past about 10 years, effective end-of-life management legislation is still lacking in many nations. Organizations like the International Renewable Energy Agency have clearly outlined the need and benefit of robust end-of-life management legislations, such as a product stewardship scheme or extended producer responsibility, to avoid a looming significant waste legacy. This article explores a possible design of an end-of-life legislation for solar photovoltaic panels including new and existing panels, necessary legislation for a second-hand economy for solar photovoltaic panels, and options for necessary levies to support an emerging recycling industry for solar panels. The article also tries to make recommendations for a product stewardship scheme for solar photovoltaic panels and its financial support. /abstract

Cosmology with Phase 1 of the Square Kilometre Array Red Book 2018: Technical specifications and performance forecasts
Publisher: Cambridge University Press (CUP)
Date: 2020
DOI: 10.1017/PASA.2019.51
Abstract: We present a detailed overview of the cosmological surveys that we aim to carry out with Phase 1 of the Square Kilometre Array (SKA1) and the science that they will enable. We highlight three main surveys: a medium-deep continuum weak lensing and low-redshift spectroscopic HI galaxy survey over 5 000 deg 2 a wide and deep continuum galaxy and HI intensity mapping (IM) survey over 20 000 deg 2 from $z = 0.35$ to 3 and a deep, high-redshift HI IM survey over 100 deg 2 from $z = 3$ to 6. Taken together, these surveys will achieve an array of important scientific goals: measuring the equation of state of dark energy out to $z \\sim 3$ with percent-level precision measurements of the cosmic expansion rate constraining possible deviations from General Relativity on cosmological scales by measuring the growth rate of structure through multiple independent methods mapping the structure of the Universe on the largest accessible scales, thus constraining fundamental properties such as isotropy, homogeneity, and non-Gaussianity and measuring the HI density and bias out to $z = 6$ . These surveys will also provide highly complementary clustering and weak lensing measurements that have independent systematic uncertainties to those of optical and near-infrared (NIR) surveys like Euclid , LSST, and WFIRST leading to a multitude of synergies that can improve constraints significantly beyond what optical or radio surveys can achieve on their own. This document, the 2018 Red Book , provides reference technical specifications, cosmological parameter forecasts, and an overview of relevant systematic effects for the three key surveys and will be regularly updated by the Cosmology Science Working Group in the run up to start of operations and the Key Science Programme of SKA1.

The optimal SAM surface functional group for producing a biomimetic HA coating on Ti
Publisher: Wiley
Date: 24-03-2006
DOI: 10.1002/JBM.A.30641
Abstract: Commercial interest is growing in biomimetic methods that employ self assembled mono-layers (SAMs) to produce biocompatible HA coatings on Ti-based orthopedic implants. Recently, separate studies have considered HA formation for various SAM surface functional groups. However, these have often neglected to verify crystallinity of the HA coating, which is essential for optimal bioactivity. Furthermore, differing experimental and analytical methods make performance comparisons difficult. This article investigates and evaluates HA formation for four of the most promising surface functional groups: --OH, --SO(3)H, --PO(4)H(2) and --COOH. All of them successfully formed a HA coating at Ca/P ratios between 1.49 and 1.62. However, only the --SO(3)H and --COOH end groups produced a predominantly crystalline HA. Furthermore, the --COOH end group yielded the thickest layer and possessed crystalline characteristics very similar to that of the human bone. The --COOH end group appears to provide the optimal SAM surface interface for nucleation and growth of biomimetic crystalline HA. Intriguingly, this finding may lend support to explanations elsewhere of why human bone sialoprotein is such a potent nucleator of HA and is attributed to the protein's glutamic acid-rich sequences.

High-performance supercapacitors using graphene/polyaniline composites deposited on kitchen sponge
Publisher: IOP Publishing
Date: 26-01-2015
DOI: 10.1088/0957-4484/26/7/075702
Abstract: We in this study used a commercial grade kitchen sponge as the scaffold where both graphene platelets (GnPs) and polyaniline (PANi) nanorods were deposited. The high electrical conductivity of GnPs (1460 S cm(-1)) enhances the pseudo-capacitive performance of PANi grown vertically on the GnPs basal planes the interconnected pores of the sponge provide sufficient inner surface between the GnPs/PANi composite and the electrolyte, which thus facilitates ion diffusion during charge and discharge processes. When the composite electrode was used to build a supercapacitor with two-electrode configuration, it exhibited a specific capacitance of 965.3 F g(-1) at a scan rate of 10 mV s(-1) in 1.0 M H2SO4 solution. In addition, the composite Nyquist plot showed no semicircle at high frequency corresponding to a low equivalent series resistance of 0.35 Ω. At 100 mV s(-1), the supercapacitor demonstrated an energy density of 34.5 Wh kg(-1) and a power density of 12.4 kW kg(-1) based on the total mass of the active materials on both electrodes. To demonstrate the performance, we built an array consisting of three cells connected in series, which lit up a red light emitting diode for five minutes. This simple method holds promise for high-performance yet low-cost electrodes for supercapacitors.

Hydrophobic Plasma Polymer Coated Silica Particles for Petroleum Hydrocarbon Removal
Publisher: American Chemical Society (ACS)
Date: 27-08-2013
DOI: 10.1021/AM4020154
Abstract: In recent years, functionalized hydrophobic materials have attracted considerable interest as oil removal agents. This investigation has applied plasma polymerization as a novel method to develop hydrophobic and oleophilic particles for water purification. 1,7-Octadiene was plasma polymerized onto silica particles using a radio frequency inductively coupled reactor fitted with a rotating chamber. Plasma polymerized 1,7-octadiene (ppOD) films were deposited using plasma power of 40 W and monomer flow rate of 2 sccm, while polymerization time was varied from 5 to 60 min. The surface chemistry of ppOD coated particles was investigated via X-ray photoelectron spectroscopy and time-of-flight secondary ion mass spectroscopy, while Washburn capillary rise measurements were applied to evaluate the hydrophobicity and oleophilicity of the particles. The effectiveness of ppOD coated particles for the removal of hydrophobic matter from water was demonstrated by adsorption of motor oil, kerosene, and crude oil. Petroleum hydrocarbon removal was examined by varying removal time and particle mass. The morphology of oil-loaded ppOD coated particles was examined via environmental scanning electron microscopy observations. Increasing the polymerization time increased the concentration of hydrocarbon functionalities on the surface, thus also increasing the hydrophobicity and oil removal efficiency (ORE). The ppOD coated particles have shown to have excellent ORE. These particles were capable of removing 99.0-99.5% of high viscosity motor oil in 10 min, while more than 99.5% of low viscosity crude oil and kerosene was adsorbed in less than 30 s. Plasma polymerization has shown to be a promising approach to produce a new class of materials for a fast, facile, and efficient oil removal.

Abstract: In this communication, we demonstrate that there is an optimum gadolinium oxide (Gd(2)O(3)) nanoparticle size of 2.3 nm in the presence of Gd(2)O(3) particles smaller and larger than this critical size, the spin-lattice relaxation rate (T(1) = 1/r(1)) of water protons at 7.0 T drastically decreases. Since r(1) is directly related to the quality of magnetic resonance imaging, the results presented here have significant implications for clinical diagnostics.

DOI: 10.1088/0957-4484/26/11/112001
Abstract: Carbon nanomaterials including carbon black (CB), carbon nanotubes (CNTs) and graphene have attracted increasingly more interest in academia due to their fascinating properties. These nanomaterials can significantly improve the mechanical, electrical, thermal, barrier, and flame retardant properties of elastomers. The improvements are dependent on the molecular nature of the matrix, the intrinsic property, geometry and dispersion of the fillers, and the interface between the matrix and the fillers. In this article, we briefly described the fabrication processes of elastomer composites, illuminated the importance of keeping fillers at nanoscale in matrices, and critically reviewed the recent development of the elastomeric composites by incorporating CB, CNTs, and graphene and its derivatives. Attention has been paid to the mechanical properties and electrical and thermal conductivity. Challenges and further research are discussed at the end of the article.

The results indicate that sugar at concentrations of up to 800 g/L can be removed by SES at a relatively high dose of 250 to 300 g/L. Based on these results, process water from a soft drink filling station which was contaminated by sugar, flavour components, Escherichia coli, Pseudomonas aeruginosa bacteria and Candida pelliculosa yeast were treated to study the performance of SES using actual process water s les by analysing turbidity, biological oxygen demand (BOD), UV absorption, and various other standard parameters, and microbial tests. The study shows that at a dose of 100 g/L of SES bacterial contamination as well as turbidity, BOD and UV absorption can be significantly reduced. However, the study found the yeast species Candida pelliculosa could not be removed from the water s les.

Abstract: Silver nanoparticles (AgNPs) have emerged as a powerful weapon against antibiotic resistant microorganisms. However, most conventional AgNPs syntheses require the use of hazardous chemicals and generate toxic organic waste. Hence, in recent year's, plant derived and biomolecule based synthetics have has gained much attention. Cacao has been used for years for its medicinal benefits and contains a powerful reducing agent - oxalic acid. We hypothesized that, due to the presence of oxalic acid, cacao extract is capable of reducing silver nitrate (AgNO3) to produce AgNPs. In this study, AgNPs were synthesized by using natural cacao extract as a reducing and stabilizing agent. The reaction temperature, time and reactant molarity were varied to optimize the synthesis yield. UV-visible spectroscopy (UV-vis), dynamic light scattering (DLS) and transmission electron microscopy (TEM) characterization demonstrated that the synthesized AgNPs were spherical particles ranging in size from 35 to 42.5nm. The synthesized AgNPs showed significant antibacterial activity against clinically relevant pathogens such as Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Staphylococcus epidermidis. Importantly, these green AgNPs are not cytotoxic to human dermal fibroblasts (HDFs) at concentrations below 32μg/ml. We conclude that cacao-based synthesis is a reproducible and sustainable method for the generation of stable antimicrobial silver nanoparticles with low cytotoxicity to human cells. The AgNPs synthesized in this work have promising properties for applications in the biomedical field.

Plasma polymerized allylamine coated quartz particles for humic acid removal
Publisher: Elsevier BV
Date: 08-2012
DOI: 10.1016/J.JCIS.2012.05.002
Abstract: Allylamine plasma polymerization has been used to modify the surface of quartz particles for humic acid removal via an inductively coupled rotating barrel plasma reactor. Plasma polymerized allylamine (ppAA) films were deposited at a power of 25 W, allylamine flow rate of 4.4 sccm and polymerization times of 5-60 min. The influence of polymerization time on surface chemistry was investigated via X-ray photoelectron spectroscopy (XPS), time of flight secondary ion mass spectrometry (ToF-SIMS) and electrokinetic analysis. Acid orange 7 adsorption/desorption quantified the number of surface amine groups. Humic acid removal via ppAA quartz particles was examined by varying pH, removal time, humic acid concentration, and particle mass. Increasing the polymerization time increased the concentration of amine groups on the ppAA quartz surface, thus also increasing the isoelectric point. ToF-SIMS demonstrated uniform distribution of amine groups across the particle surface. Greatest humic acid removal was observed at pH 5 due to electrostatic attraction. At higher pH values, for longer polymerization times, humic acid removal was also observed due to hydrogen bonding. Increasing the initial humic acid concentration increased the mass of humic acid removed, with longer polymerization times exhibiting the greatest increases. Plasma polymerization using a rotating plasma reactor has shown to be a successful method for modifying quartz particles for the removal of humic acid. Further development of the plasma polymerization process and investigation of additional contaminants will aid in the development of a low cost water treatment system.

DOI: 10.1557/PROC-275-627
Abstract: The 2212 phase exhibits an extended single phase region having a variable Sr/Ca ratio and Bi-content of 2.1 Bi 2.3. At T = 820°C the single phase region extends between 2.05/0.95 Sr/Ca 1.2/1.8, whereas, at T = 870° C the single phase region extends between 2.2/0.8 Sr/Ca 1.6/1.4. The 2223 phase exhibits a significant higher Bi-content of Bi ∼ 2.5 compared to the formal composition Bi 2 Sr 2 Ca 2 Cu 3 O 10 . The Sr/Ca ratio varies between 2/2 Sr/Ca 1.9/2.1 reffering to Cu-content of Cu = 3. S les with the nominal composition Bi 2.5 Sr 2 Ca 2 Cu 3 O x and Bi 2.5 Sr 1.9 Ca 2.1 Cu 3 O x have been sintered at 880 – 885°C for 90 h in air and consist of 90 – 95 volume percent 2223 phase. T c depends on the chemical composition of the phases. With decreasing C a - and Bi-content of the phases T c increases. Both phases are metastable at roomtemperature. 2212 and 2223 rapidly decompose at 600 °C and 800 °C in air, respectively. At 300°c two new Bi-Sr-Cuprates have been found.

Plasma Polymer-Functionalized Silica Particles for Heavy Metals Removal
Publisher: American Chemical Society (ACS)
Date: 11-02-2015
DOI: 10.1021/AM508637K
Abstract: Highly negatively charged particles were fabricated via an innovative plasma-assisted approach for the removal of heavy metal ions. Thiophene plasma polymerization was used to deposit sulfur-rich films onto silica particles followed by the introduction of oxidized sulfur functionalities, such as sulfonate and sulfonic acid, via water-plasma treatments. Surface chemistry analyses were conducted by X-ray photoelectron spectroscopy and time-of-flight secondary ion mass spectroscopy. Electrokinetic measurements quantified the zeta potentials and isoelectric points (IEPs) of modified particles and indicated significant decreases of zeta potentials and IEPs upon plasma modification of particles. Plasma polymerized thiophene-coated particles treated with water plasma for 10 min exhibited an IEP of less than 3.5. The effectiveness of developed surfaces in the adsorption of heavy metal ions was demonstrated through copper (Cu) and zinc (Zn) removal experiments. The removal of metal ions was examined through changing initial pH of solution, removal time, and mass of particles. Increasing the water plasma treatment time to 20 min significantly increased the metal removal efficiency (MRE) of modified particles, whereas further increasing the plasma treatment time reduced the MRE due to the influence of an ablation mechanism. The developed particulate surfaces were capable of removing more than 96.7% of both Cu and Zn ions in 1 h. The combination of plasma polymerization and oxidative plasma treatment is an effective method for the fabrication of new adsorbents for the removal of heavy metals.

Development of Oxidized Sulfur Polymer Films through a Combination of Plasma Polymerization and Oxidative Plasma Treatment
Publisher: American Chemical Society (ACS)
Date: 29-01-2014
DOI: 10.1021/LA4045489
Abstract: A novel two-step process consisting of plasma polymerization and oxidative plasma treatment is introduced in this article for the first time for the fabrication of -SO(x)(H)-functionalized surfaces. Plasma-polymerized thiophene (PPT) was initially deposited onto silicon wafers and subsequently SO(x)(H)-functionalized using air or oxygen plasma. The effectiveness of both air and oxygen plasma treatments in introducing sulfur-oxygen groups into the PPT film was investigated as the plasma input specific energy and treatment time were varied. The surface chemistries of untreated and treated PPT coatings were analyzed by X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectroscopy (ToF-SIMS), whereas spectroscopic ellipsometry was used to evaluate the film thickness and ablation rate. Surface chemistry analyses revealed that high concentrations of -SO(x)(H) functionalities were generated on the surface upon either air or oxygen plasma treatment. It was found that, at low plasma input energies, the oxidation process was dominant whereas, at higher energies, ablation of the film became more pronounced. The combination of thiophene plasma polymerization and air/oxygen plasma treatment was found to be a successful approach to the fabrication of -SO(x)(H)-functionalized surfaces.

Melt compounding with graphene to develop functional, high-performance elastomers
Publisher: IOP Publishing
Date: 27-03-2013
DOI: 10.1088/0957-4484/24/16/165601
Abstract: Rather than using graphene oxide, which is limited by a high defect concentration and cost due to oxidation and reduction, we adopted cost-effective, 3.56 nm thick graphene platelets (GnPs) of high structural integrity to melt compound with an elastomer-ethylene-propylene-diene monomer rubber (EPDM)-using an industrial facility. An elastomer is an amorphous, chemically crosslinked polymer generally having rather low modulus and fracture strength but high fracture strain in comparison with other materials and upon removal of loading, it is able to return to its original geometry, immediately and completely. It was found that most GnPs dispersed uniformly in the elastomer matrix, although some did form clusters. A percolation threshold of electrical conductivity at 18 vol% GnPs was observed and the elastomer thermal conductivity increased by 417% at 45 vol% GnPs. The modulus and tensile strength increased by 710% and 404% at 26.7 vol% GnPs, respectively. The modulus improvement agrees well with the Guth and Halpin-Tsai models. The reinforcing effect of GnPs was compared with silicate layers and carbon nanotube. Our simple fabrication would prolong the service life of elastomeric products used in dynamic loading, thus reducing thermosetting waste in the environment.
SuperCLASS – I. The super cluster assisted shear survey: Project overview and data release 1
Publisher: Oxford University Press (OUP)
Date: 02-04-2020
Abstract: The SuperCLuster Assisted Shear Survey (SuperCLASS) is a legacy programme using the e-MERLIN interferometric array. The aim is to observe the sky at L-band (1.4 GHz) to a r.m.s. of $7\\, \\mu {\\rm Jy}\\,$beam−1 over an area of $\\sim 1\\, {\\rm deg}^2$ centred on the Abell 981 supercluster. The main scientific objectives of the project are: (i) to detect the effects of weak lensing in the radio in preparation for similar measurements with the Square Kilometre Array (SKA) (ii) an extinction free census of star formation and AGN activity out to z ∼ 1. In this paper we give an overview of the project including the science goals and multiwavelength coverage before presenting the first data release. We have analysed around 400 h of e-MERLIN data allowing us to create a Data Release 1 (DR1) mosaic of $\\sim 0.26\\, {\\rm deg}^2$ to the full depth. These observations have been supplemented with complementary radio observations from the Karl G. Jansky Very Large Array (VLA) and optical/near infrared observations taken with the Subaru, Canada-France-Hawaii, and Spitzer Telescopes. The main data product is a catalogue of 887 sources detected by the VLA, of which 395 are detected by e-MERLIN and 197 of these are resolved. We have investigated the size, flux, and spectral index properties of these sources finding them compatible with previous studies. Preliminary photometric redshifts, and an assessment of galaxy shapes measured in the radio data, combined with a radio-optical cross-correlation technique probing cosmic shear in a supercluster environment, are presented in companion papers.
Phase Equilibrium Diagrams of the Binary Systems LaMnO3-SrMnO3 and LaMnO3-CaMnO3
Publisher: Springer Science and Business Media LLC
Date: 1999
DOI: 10.1557/PROC-602-327
Abstract: The quasi binary systems LaMnO 3 – SrMnO 3 and LaMnO 3 – CaMnO 3 have been studied. Both systems show a miscibility gap below about 1400°C in air. This phenomenon causes the decomposition of single phase (La,Sr)MnO 3−x and (La,Ca)MnO 3−x solid solution with intermediate La:Sr or La:Ca ratios into La rich SrMnO 3−x or CaMnO 3−x and Sr or Ca rich LaMnO 3−x at lower temperatures. At 1400°C a structure transformation of (La,Sr)MnO 3 from orthorhombic to rombohedral has not been observed and the structure of La 0.7 Sr 0.3 MnO 3 has been determined to be orthorhombic with a = 0.54927 ± 0.0009 nm, b = 0.54582 ± 0.0009 nm, and c = 0.76772 ± 0.0034 nm.
Deposition of Silver and Gold Nanoparticles on Surface Engineered Silica Particles and Their Potential Applications
Publisher: American Scientific Publishers
Date: 10-2012
Abstract: This study focuses the attachment of gold and silver nanoparticles on commercial micron sized silica particles. The silica was functionalized with amine groups by a commercial silane surfactant and a layer-by-layer process employing polyelectrolytes, respectively. The nanoparticles were produced by conventional water based processes and the nanoparticles were functionalised by poly acrylic acid. The chemical analysis and X-ray photoelectron spectrometry clearly shows that the gold and silver nanoparticles can be attached to the functionalized silica by the used approaches. However, silane functionalized silica appears to result in a much more efficient uptake of the nanoparticles compared to layer-by-layer functionalized silica. 99% of gold and silver nanoparticle could be recovered and attached to the surface of the silane functionalized silica resulting in a concentration of 0.89 micromolAg/gSES (0.096 mgAg/gSES) and 1.53 micromolAu/gSES (0.301 mgAu/gSES) on the surface of the silica particles. The silver and gold coated silica particles were used for removal of Escherichia coli bacteria and radio frequency (RF) heating, respectively. The test indicate that the bactericide properties of silver and the RF heating effect of gold nanoparticles can be retained by attaching the nanoparticles to silica.

DOI: 10.1155/2013/839016
Abstract: Silver and copper nanoparticles, respectively, were produced on glass slides via magnetron sputtering. The experiments show that with magnetron sputtering the size and concentration of the nanoparticles can be easily controlled via sputter time and plasma power. Silver nanoparticles grow much faster than copper nanoparticles, which also require higher plasma power for their synthesis. Exposed to albumin solution, the glass slides with silver nanoparticles clearly show a delay in albumin attachment compared to pure glass slides. Glass slides with copper nanoparticles show a slight attachment of albumin even after 3 h of exposure. However, the albumin concentration on the surface of the glass slides was much smaller compared to pure glass slides and did not increase within 24 h.

Biomimetic hydroxyapatite coating on glass coverslips for the assay of osteoclast activity in vitro
Publisher: Springer Science and Business Media LLC
Date: 04-03-2009
DOI: 10.1007/S10856-009-3718-0
Abstract: The osteoclast (OC) is the cell type responsible for the resorption of bone. The activity of this cell is important in the aetiology of a large number of skeletal pathologies, and also for the biocompatibility and osseointegration of orthopaedic implant materials. OC mediated acid hydrolysis of calcium phosphate from the bone matrix offers a prime means of studying the biology and activity of this cell type. We have developed a method of coating glass coverslips with a hydroxyapatite (HA)-like mineral, using a biomimetic approach. Hydroxylation followed by formation of a self assembled monolayer (SAM) using the surfactant triethoxysilylpropyl succinic anhydride (TESPSA), allowed biomimetic deposition of HA-like mineral from a simulated body fluid (SBF). The biocompatibility of the TESPSA SAM-HA coated glass coverslips was tested by culturing human mature OC present in s les of giant cell tumour of bone (GCT). Parameters of OC activity were assayed, including F-actin ring formation, release of calcium and formation of osteoclastic resorption pits, confirming that OC were able to attach to and resorb the coated surface. This approach for the preparation of HA coatings on glass coverslips could have wide applicability for the study of osteoclast behaviour in vitro.
SuperCLASS – III. Weak lensing from radio and optical observations in Data Release 1
Publisher: Oxford University Press (OUP)
Date: 02-04-2020
Abstract: We describe the first results on weak gravitational lensing from the SuperCLASS survey: the first survey specifically designed to measure the weak lensing effect in radio-wavelength data, both alone and in cross-correlation with optical data. We analyse $1.53 \\, \\mathrm{deg}^2$ of optical data from the Subaru telescope and $0.26 \\, \\mathrm{deg}^2$ of radio data from the e-MERLIN and VLA telescopes (the DR1 data set). Using standard methodologies on the optical data only we make a significant (10σ) detection of the weak lensing signal (a shear power spectrum) due to the massive supercluster of galaxies in the targeted region. For the radio data we develop a new method to measure the shapes of galaxies from the interferometric data, and we construct a simulation pipeline to validate this method. We then apply this analysis to our radio observations, treating the e-MERLIN and VLA data independently. We achieve source densities of $0.5 \\,$ arcmin−2 in the VLA data and $0.06 \\,$ arcmin−2 in the e-MERLIN data, numbers which prove too small to allow a detection of a weak lensing signal in either the radio data alone or in cross-correlation with the optical data. Finally, we show preliminary results from a visibility-plane combination of the data from e-MERLIN and VLA which will be used for the forthcoming full SuperCLASS data release. This approach to data combination is expected to enhance both the number density of weak lensing sources available, and the fidelity with which their shapes can be measured.

High-performance supercapacitors using graphene/polyaniline composites deposited on kitchen sponge
Publisher: IOP Publishing
Date: 26-01-2015
DOI: 10.1088/0957-4484/26/7/075702
Abstract: We in this study used a commercial grade kitchen sponge as the scaffold where both graphene platelets (GnPs) and polyaniline (PANi) nanorods were deposited. The high electrical conductivity of GnPs (1460 S cm(-1)) enhances the pseudo-capacitive performance of PANi grown vertically on the GnPs basal planes the interconnected pores of the sponge provide sufficient inner surface between the GnPs/PANi composite and the electrolyte, which thus facilitates ion diffusion during charge and discharge processes. When the composite electrode was used to build a supercapacitor with two-electrode configuration, it exhibited a specific capacitance of 965.3 F g(-1) at a scan rate of 10 mV s(-1) in 1.0 M H2SO4 solution. In addition, the composite Nyquist plot showed no semicircle at high frequency corresponding to a low equivalent series resistance of 0.35 Ω. At 100 mV s(-1), the supercapacitor demonstrated an energy density of 34.5 Wh kg(-1) and a power density of 12.4 kW kg(-1) based on the total mass of the active materials on both electrodes. To demonstrate the performance, we built an array consisting of three cells connected in series, which lit up a red light emitting diode for five minutes. This simple method holds promise for high-performance yet low-cost electrodes for supercapacitors.

Abstract: Polyaniline (PANi)/graphene nanocomposites have attracted tremendous interest because of their great potential in electrochemical energy storage applications, especially supercapacitors. We herein focus on the composite synthesis, device fabrication and particularly various techniques for the improvement of electrochemical performance. It is imperative to take close control of the interface in these nanostructured composites, which thus would lead to the desired synergistic effects and cyclic stability with the efficient diffusion of electrolyte ions and electrons. Challenges and perspectives are discussed for the development of highly efficient PANi/graphene electrodes for supercapacitors.

Abstract: The quasi binary systems LaMnO 3 – SrMnO 3 and LaMnO 3 – CaMnO 3 have been studied. Both systems show a miscibility gap below about 1400°C in air. This phenomenon causes the decomposition of single phase (La,Sr)MnO 3−x and (La,Ca)MnO 3−x solid solution with intermediate La:Sr or La:Ca ratios into La rich SrMnO 3−x or CaMnO 3−x and Sr or Ca rich LaMnO 3−x at lower temperatures. At 1400°C a structure transformation of (La,Sr)MnO 3 from orthorhombic to rombohedral has not been observed and the structure of La 0.7 Sr 0.3 MnO 3 has been determined to be orthorhombic with a = 0.54927 ± 0.0009 nm, b = 0.54582 ± 0.0009 nm, and c = 0.76772 ± 0.0034 nm.

Ultra small Gd2O3 nanoparticles: Absorption and emission properties
Publisher: Elsevier BV
Date: 02-2011
DOI: 10.1016/J.JCIS.2010.11.012
Abstract: In this paper, we report a facile method for synthesis of ultra small (1-3nm) gadolinium oxide (Gd(2)O(3)) nanoparticles using citric acid (CA) as a capping agent. The dependence of nanoparticle (NP) size on the ratio between CA and gadolinium (Gd) is investigated. Absorption properties of the ultra small Gd(2)O(3) NPs in UV region have four characteristic peaks at 312nm, 274nm, 253nm and 228nm. Finally, we show that the Gd(2)O(3) nanoparticles synthesized by this method induce triplet emission (phosphorescence) from CA and EG in the NIR region.

Influence of immobilized quaternary ammonium group surface density on antimicrobial efficacy and cytotoxicity
Publisher: Informa UK Limited
Date: 21-12-2015
DOI: 10.1080/08927014.2015.1115977
Abstract: Bacterial colonization of medical devices causes infections and is a significant problem in healthcare. The use of antibacterial coatings is considered as a potential solution to this problem and has attracted a great deal of attention. Using concentration density gradients of immobilized quaternary ammonium compounds it was demonstrated that a specific threshold of surface concentration is required to induce significant bacterial death. It was determined that this threshold was 4.18% NR4(+) bonded nitrogen with a surface potential of + 120.4 mV. Furthermore, it is shown for the first time that adhesion of constituents of the culture medium to the quaternary ammonium modified surface eliminated any cytotoxicity towards eukaryotic cells such as primary human fibroblasts. The implications of this type of surface fouling on the antimicrobial efficacy of surface coatings are also discussed.

Phase diagram studies in the quasi binary systems LaMnO3–SrMnO3 and LaMnO3–CaMnO3
Publisher: Springer Science and Business Media LLC
Date: 05-2000
Abstract: The quasi binary systems LaMnO 3 –SrMnO 3 and LaMnO 3 –CaMnO 3 were studied. Both systems show a miscibility gap at intermediate La:Sr and La:Ca ratios below about 1400 °C in air. This phenomenon causes the decomposition of single-phase (La,Sr)MnO 3− x and (La,Ca)MnO 3− x solid solution into La-rich SrMnO 3− x + Sr-rich LaMnO 3− x and La-rich CaMnO 3− x + Ca-rich LaMnO 3− x at lower temperatures, respectively. At 1400 °C in the system LaMnO 3 –SrMnO 3 , a structure transformation of (La,Sr)MnO 3 from orthorhombic to rhombohedral with increasing Sr content was not observed, and the structure of La 0.7 Sr 0.3 MnO 3 was determined to be orthorhombic with a = 0.54927 ± 0.0009 nm, b = 0.54582 ± 0.0009 nm, and c 4 0.76772 ± 0.0034 nm.
