The face-centered cubic (fcc) type magnesium-zirconium hydride (Mg0.82Zr0.18Hx) was synthesized by means of the ultrahigh pressure (UHP) technique, which could generate 8 GPa of hydrogen pressure. The differential scanning calorimeter (DSC) measurements indicated that the fcc phase exhibited reversible hydrogen releas…

Abstract Three different size CdTe quantum dots (QDs) capped by 3‐mercaptopropionic acid (MPA) have been prepared in aqueous solutions, and their interactions with Cu 2+ and Hg 2+ have been investigated. The opposite size‐dependent fluorescence quenching of CdTe QDs by Hg 2+ and Cu 2+ was observed: Hg 2+ quenched smal…
Abstract Understanding the fundamental mechanisms that govern the foaming process is the most essential universal prerequisite for developing effective processing strategies for fabricating high‐quality foamed plastic products using any type of foaming technology. Despite chemically blown foaming of thermoplastics und…
The cyclopentadienyl metal–carbonyls CpFe(CO) 2 Cl and CpMo(CO) 3 Cl, and their 1:1 inclusion complexes with β-cyclodextrin (β-CD) and permethylated β-CD (TRIMEB), were prepared, and the TRIMEB adduct with CpFe(CO) 2 Cl was structurally characterized by single-crystal X-ray diffraction. The complex crystallizes in the…
Unreacted residual limestone in the container substrate is key in buffering pH change over time. Our goal was to develop a substrate test protocol to measure residual lime [in units of CaCO 3 equivalent (CCE)] by applying a strong mineral acid (HCl) to a substrate sample and measuring the evolved CO 2 gas with a gasom…
Active transport mechanisms, relying on motor proteins or polymerization of cytoskeletal filaments, play a central role in the uptake of nanoparticles by cells. While active transport can enhance the effectiveness of nanoparticle therapeutics, it also contributes to the toxicity of nanoparticles released to the enviro…
Two phenyl‐tolane compounds with two pairs of (2,3) lateral difluoro substitutions were synthesized and their properties evaluated. These compounds exhibit a high birefringence (Δn ∼ 0.35) and a large negative dielectric anisotropy (Δε∼ −8). These two important features make the phenyl‐tolane compounds useful as a dop…
The design of a new type of left-handed material (LHM), having two dimensions of negative permittivities and one dimension of negative permeability, is presented in this paper for the observation and demonstration of the LH properties of Čerenkov radiation, which is a transverse magnetic (TM) electromagnetic wave. For…
Polycrystalline zinc nitride films are deposited on Corning 7059 glass substrates by pulsed filtered cathodic vacuum arc deposition (PFCVAD). The crystallographic structure is studied by means of x-ray diffraction. These measurements show that all the films are crystallized in the cubic structure, in a preferred orien…
Films constructed layer-by-layer on electrodes with architecture {protein/hyaluronic acid (HA)}n containing myoglobin (Mb) or horseradish peroxidase (HRP) were protected against protein damage by H2O2 by using outer catalase layers. Peroxidase activity for substrate oxidation requires activation by H2O2, but {protein/…
The extract of Datura stramonium has been studied as a possible source of green inhibitor for corrosion of mild steel (MS) in HCl and H 2 SO 4 media at different temperatures. The anticorrosion effect was evaluated by conventional weight loss studies, electrochemical studies viz., Tafel polarization, ac impedance, and…
Abstract Magnetic refrigeration based on the magnetocaloric effect (MCE) becomes a topic of internationally current interest. This enabling technology provides several advantages (e.g. high energy efficiency, small volume, non‐pollution) over a conventional gas compression technique. It depends heavily upon the magnit…
Because weathering of minerals releases chemical elements into the biogeochemical cycle, characterization of their weathering products helps to better model groundwater quality, formation of secondary minerals and nutrient flux through the trophic chain. Based on microscopic and elemental analyses, weathering of rioda…
Zn K-edge XANES in ZnO has been calculated within the full-multiple-scattering (FMS) and finite difference method (FDM) formalism using the ab initio FDMNES code. The influence of non-muffin-tin potential, bulk defects, surface termination and polarization effects on XANES has been analysed. The obtained theoretical r…
The optical effects of liquid crystals can be realized when the mesogens are dispersed in a supporting and stabilizing polymer phase. Thermoplastics were chosen for their structural reversibility and ease of fabrication of polymer‐dispersed liquid crystals (PDLCs) from solution via solvent‐induced phase separation (SI…
Equilibrium geometries and binding energies with respect to the interaction of a methanol molecule (MeOH) with single-walled carbon nanotubes (SWCNTs) of various diameter are calculated by means of density-functional theory including an empirical energy correction for dispersion (DFT-D). This theory is validated by co…
Abstract Reactions between MgAl 2 O 4 and LiF during low-temperature sintering have been examined by transmission electron microscopy. It is shown that the presence of LiF at elevated temperatures leads to the formation of a defect MgAl 2 O 4 spinel phase containing oxygen vacancies due to the incorporation of both Li…
Abstract Reaction of GdIII(NO)3·6H2O and (Bu3NH)3[WV(CN)8] (Bu3N = tributylamine) in N,N-dimethylacetamide (DMA) yielded two types of Gd–W bimetal assemblies with noncentrosymmetric crystal structures: GdIII(DMA)n[WV(CN)8] (n=6, 1; n=5, 2). X-ray single crystal analyses showed that 1 crystallizes in the monoclinic sys…
Perovskite-structured SrTiO 3 undergoes a cubic ( Pm 3 m ) to tetragonal ( I 4/ mcm ) transition at ∼108 K ( T a ) associated with rotations of the O octahedra in the antiphase around the [001] direction. This phase transition gives rise to modes at the R point of the Brillouin zone in the Raman spectra and superlatti…
