Sodalite ( Na 8 ( AlSiO 4 ) 6 Cl 2 ) and cancrinite (( Na , K ) 6 Ca 2 ( AlSiO 4 ) 6 Cl 4 ) are environmentally stable, chloride‐containing minerals that are a logical waste form option for the mixed alkali chloride salt waste stream that is generated from a proposed electrochemical separations process during nuclear…
The radiolysis of water adsorbed on the surface of ZrO 2 nanoparticles has been examined using a variety of spectroscopic techniques. Irradiations were performed with fast electrons, γ rays, and 5 MeV helium ions. Infrared spectroscopic analysis of the surface reveals little change in the surface stoichiometry, which…
In order to determine the electronic factors that may affect the catalytic antioxidant activity of water-soluble metallocorroles a series of 10-aryl-5,15-pyridinium manganese(III) corroles was prepared. These complexes were examined regarding the effect of the C(10) substituent on the Mn(IV)/Mn(III) redox potentials,…
A novel bulk poly(acrylamide-co-vinyl phosphonic acid) (p(AAm-co-VPA)) hydrogels were synthesized via a photo polymerization technique in macro dimension. Ni and Co nanoparticles inside p(AAm-co-VPA) hydrogel were also prepared by reduction of the metal ions loaded into the hydrogel network from the corresponding meta…
Using Monte Carlo simulation techniques, we calculate the phase diagram for a square-shoulder square-well potential in two dimensions that has been previously shown to exhibit liquid anomalies consistent with a metastable liquid-liquid critical point. We consider the liquid, gas, and five crystal phases, and find that…
Thermal behavior of angiotensin II type 1 (AT1) receptor antagonist, Valsartan (VAL), was examined employing thermogravimetric analysis (TGA), standard differential scanning calorimetry (DSC) and temperature-modulated differential scanning calorimetry (TMDSC). The stability of VAL was measured by TGA from 25 to 600°C.…
In this study, the dissociation mechanism of self-assembled cyclic peptides (CPs) has been investigated using classical/steered molecular dynamics simulations combined with umbrella sampling techniques in a polar and a nonpolar solvent. The stability of cyclic peptide nanotubes (CPNTs) with different surface polarity,…
The high surface area of nanoporous electrodes makes them promising for use in electrochemical double-layer supercapacitors, desalination and pollution remediation, and drug delivery applications. When designed well and operating near their peak power, their charging rates are limited by ion transport through their lo…
A simple and efficient two-step hybrid electrochemical–thermal route was developed for the bulk synthesis of CuO nanoparticles using aqueous sodium nitrate electrolyte and Cu electrodes in an undivided cell under galvanostatic mode at room temperature. The influence of electrolyte concentration on the synthesis of CuO…
Self-assembled monolayers composed of a mixture of thiolate molecules, featuring hydrocarbon or perfluorocarbon chains (H- and F-chains) terminating with a short poly(oxoethylene) (PEG) moiety, are the most extreme example of surfactant immiscibility on gold nanoparticles reported so far. The phase segregation between…
The tribological properties of Silicon‐containing diamond‐like‐carbon (Si‐DLC) films, deposited by magnetron sputtering Si target in methane/argon atmosphere, were studied in comparison with diamond‐like‐carbon (DLC) films. The DLC films disappeared because of the oxidation in the air at 500 °C, whereas the Si‐DLC fil…
The ability to generate tailor-made, functionalized polyester (polyhydroxyalkanoate, PHA) beads in bacteria by harnessing their natural carbon-storage granule production system is an exciting recent development. Proteins that naturally attach to the polyester granule core were rationally engineered to enable in vivo p…
The synthesis of hyperbranched polyglycerol dendron analogues with precisely one focal amino functionality (H 2 N- hb PG) and their use for the synthesis of linear-hyperbranched graft-copolymers in a grafting-to approach is reported. By use of N, N -dibenzyl tris(hydroxylmethyl) aminomethane as a novel initiator for t…
The anomalies in the anti-Stokes to Stokes intensity ratios in single-molecule surface-enhanced resonance Raman scattering were investigated. Brilliant green and crystal violet dyes were the molecular probes, and the experiments were carried out on an electrochemically activated Ag surface. The results allowed new ins…
Microfluidics is used here for the first time to efficiently tune the growth conditions for understanding the build-up mechanism of exponentially growing polyelectrolyte (PE) films. The velocity of PE supply and time of interaction can be successfully altered during the layer-by-layer assembly. Another advantage of th…
A novel, entirely bio-derived polylactide carbohydrate copolymer (RP 1 ) is used as a compatibilizer, to produce bacterial cellulose (BC) poly( l -lactide) (PLLA) nanocomposites with improved mechanical properties. Contact angle measurements of RP 1 droplets on single BC nanofibres proved that it has a higher affinity…
One-step fabrication of graphene-polyaniline (graphene-PANI) hybrid film was facilely achieved by cyclic voltammetric electrolysis of a bath containing both graphene oxide (GO) and aniline, where graphene is obtained by electrochemical reduction of GO and PANI is simultaneously obtained by aniline electropolymerizatio…
In the present work, ZnO quantum dots (QDs) have been prepared by the sol-gel method, and the performance of the QDs has been improved. The effect of Cd concentration on the structural and luminescent properties of the QDs, as well as the effect of the mass ratio of trioctylphosphine oxide (TOPO)/octadecylamine (ODA),…
Graphene and its quasi-one-dimensional counterpart, graphene nanoribbons, present an ideal platform for tweaking their unique electronic, magnetic and mechanical properties by various means for potential next-generation device applications. However, such tweaking requires knowledge of the electron-electron interaction…
Heteropoly acid (SiW 12 O 40 )-based ionic liquid (SWIL) and silica supported SiW 12 O 40 -based ionic liquid (SWIL/SiO 2 ) catalysts with different contents of SWIL were designed and prepared. The structures of the catalysts were experimentally characterized and theoretically analyzed, and catalytic activities and re…
