Thin-film perovskite cobaltites have been found to exhibit coercivity values enhanced by almost 2 orders of magnitude in comparison to bulk. In this paper, we have investigated this unexplained coercivity enhancement in detail, focusing on epitaxial SrTiO${}_{3}$(001)/Nd${}_{0.5}$Sr${}_{0.5}$CoO${}_{3}$ [SrTiO${}_{3}=…
Abstract The effect of various experimental conditions (i.e., hydrogen charging current density, charging time, solution concentration, and temperature) on the embrittlement and cracking susceptibility of 2205 duplex stainless steel was studied by electrochemical hydrogen charging and slow strain rate tests. The resul…
Nanocrystalline porous CaSiO 3 ceramic powders have been synthesized by a novel low-temperature initiated self-propagating, gas-producing solution combustion method. Single phase β -CaSiO 3 (Wollastonite) is formed by calcination at 900°C for 3 h. The crystallization and phase formation temperatures in this method are…
Indomethacin is a non-steroidal anti-inflammatory drug (NSAID).It is practically insoluble in water, which precludes its use in aqueous solution formulations. The effect of arginine on the solubility of indomethacin was investigated in this study. The solubility enhancement of indomethacin by the arginine was observed…
The synthesis, structure, and magnetic properties of a ligand-modified Mn(4) dicubane single-molecule magnet (SMM), [Mn(4)(Bet)(4)(mdea)(2)(mdeaH)(2)](BPh(4))(4), are presented, where the cationic SMM units are significantly separated from neighboring molecules in the crystal lattice. There are no cocrystallized solva…
Novel nanocomposites based on aliphatic poly(ester-ether) [poly( p -dioxanone), PPDO] and fibrous clay (sepiolite) were successfully prepared by surface-initiated polymerization of p -dioxanone (PDO) in the presence of organo-modified sepiolite (OSEP). The existence of OSEP-grafted PPDO in nanocomposites, generated vi…
Several methods and corresponding parameters have been used to measure the emission intensities and efficiencies of luminescent materials (e.g., organic dyes, quantum dots, rare-earth-doped materials). The important performance parameters characterizing the emission intensities or brightness are overall quantum yield,…
Inelastic light-scattering spectra of normal and permanently densified ${\mathrm{B}}_{2}$O${}_{3}$ glasses were investigated over the frequency range between 6 and 1600 cm${}^{\ensuremath{-}1}$. Densification from 1826 to 2320 kg$/$m${}^{3}$ was obtained by loading ${\mathrm{B}}_{2}$O${}_{3}$ glasses in a multianvil a…
We design a model negative index metamaterial (NIM) based on Mie resonances in cylinders with positive permittivity ($\ensuremath{\varepsilon}$) and permeability (\ensuremath{\mu}). In the effective medium theory (EMT) the composite is a homogeneous material with $\ensuremath{\varepsilon}$ $=$ \ensuremath{\mu} $=$ \en…
Abstract The influence of the support architecture (structure and pore size) on the activity of MAO/(nBuCp) 2 ZrCl 2 heterogeneous catalysts in the polymerization of ethylene and 1‐hexene is studied through the characterization of the polymers' microstructure. SBA‐15 silica‐based mesostructured materials are synthesiz…
Abstract A fabrication setup was specially designed so that one stream of sol of polyvinyl pyrrolidone (PVP), electrospun to form a bundle of fibers, acted as an axis between two rotating needles, and a second stream of PVP sol containing copper nitrate was electrospun around the fiber bundle axis to form a coil. This…
As organic liquids are cooled to become glasses, crystal growth at the free surface can be substantially faster than in the interior, a phenomenon uncommon for other materials and for which different explanations exist. We have measured the surface and bulk growth rates of three polymorphs in carbamazepine glasses. Cr…
With the aim at controlling cellulose degradation phenomena, the natural aging of Whatman paper samples was simulated through different artificial aging processes: thermal oxidation in air at constant temperature, photo-oxidation under Xenon arc lamp, accelerating ageing in climatic chamber, and chemical oxidation wit…
This article reviews the use of multifunctional polymers founded on high-molecular weight poly(ethylene glycol) (PEG). The design of new PEG derivatives assembled in a dendrimer-like multimeric fashion or bearing different functionalities on the same molecule is described. Their use as new drug delivery systems based…
Abstract Solidification structure of wheel steel round billet during the continuous casting process was simulated using FE (Finite Element)–CA (Cellular Automaton) coupling model. Variation of thermo‐physical parameters during solidification was considered based on a thermodynamic database. Meanwhile effect of electro…
Abstract By anodic potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques, the effect of recrystallization on the corrosion and electrochemical behaviour of Ti12Mo and Ti12Mo5Ta alloys was studied. Aerated Ringer's solution was employed as electrolyte solution at 37 °C. The pH was 6.9…
We report the successful preparation of alkali-carbonate-supported aluminosilicate catalysts for diesel soot combustion. From the views of practical feasibility as well as economic and environmental concerns, utilizing alkali metals is preferable for diesel soot combustion. We overcome the drawback that the alkali com…
Abstract The performance of the selected inhibitors, including thioglycolic acid (TGA), diethylenetriamine (DETA), and naphthene acid imidazolines (IM), on the bare surface of N80 steel and its scaled surface pre‐corroded in CO 2 ‐saturated 1%NaCl solution was investigated by weight‐loss method, electrochemical measur…
This paper investigates the electron and phonon transport and their implications for performance and reliability of single-walled carbon nanotube (SWCNT), double-walled carbon nanotube (DWCNT), and multiwalled carbon nanotube (MWCNT) vias-possibly the most imminent application of carbon nanotube (CNT)-based components…
Rectangular waveguides loaded by anisotropic metamaterials are analyzed to assess the controllability of transmission characteristics of the involved electromagnetic waves. Dispersion relations of TEm0modes in the metamaterial-loaded waveguide (MLW) are theoretically investigated. It is shown that all propagating mode…
