We report on maximum entropy method study of the experimental atomic and ionic charges of LiBD${}_{4}$ in its low-temperature orthorhombic phase. Synchrotron radiation x-ray powder diffraction data, neutron powder diffraction data, and density functional calculations were used. The atomic and ionic charges were determ…
Growth of cells in 3-D porous scaffolds has gained importance in the field of tissue engineering. The scaffolds guide cellular growth, synthesize extracellular matrix and other biological molecules, and make the formation of tissues and functional organs easier. The aim of this study is to use α-tricalcium phosphate c…
Abstract Phenolphthalein poly(ether ketone) (PEK‐C) was blended with the diglycidyl ether of bisphenol A epoxy resin and bisphenol A dicyanate ester. The effect of cyanate content on cure behaviors, thermal and mechanical properties of PEK‐C/epoxy/cyanate mixtures was investigated. As results, the increase of cyanate…
We theoretically describe the spin-excitation spectrum of a two-dimensional electron gas embedded in a quantum well with localized magnetic impurities. Compared to the previous work published in [Phys. Rev. B 70, 45205 (2004)] and [Phys. Rev. B 79, 045306 (2009)], we introduce equations that allow us to consider the i…
Two different concentrations of CdCl(2) and (NH(2))(2)CS were used to prepare CdS thin films, to be deposited on glass substrate by chemical bath deposition (CBD) technique. CdCl(2) (0.000312 M and 0.000625 M) was employed as a source of Cd(2+) while (NH(2))(2)CS (0.00125 M and 0.000625 M) for S(2-) at a constant bath…
The gelsolin related actin binding protein, Flii, is able to regulate wound healing; mice with decreased Flii expression show improved wound healing whereas mice with elevated Flii expression exhibit impaired wound healing. In both mice and humans Flii expression increases with age and amelioration of FLII activity re…
Since they first appearance at the end of the 1980's, organic transistors have been experiencing a growing interest from both academic and industrial institutions. In this short review, we address the current state-of-the-art of this new kind of electronic device. In particular, we try to define what characterizes an…
Under a perpendicular spin-transfer-torque (STT) polarizer and in-plane (IP) bias magnetic field, three-dimensional instability thresholds of the critical strength of STT and the field are derived from an effective one-dimensional free energy. The modified astroids derived from the STT and IP fields are quite differen…
Abstract In this study, for the first time, a nano ceramic material of Al2O3 was used as thermal barrier coating in a diesel engine. In the first phase, engine combustion chamber elements (cylinder head, cylinder liner, valves, and piston crown face) were coated with 200 μm thickness nano ceramic material of Al2O3 by…
We present a joint experimental and theoretical study of the superconducting phase of the layered binary silicide BaSi(2). Compared with the AlB(2) structure of graphite or diboridelike superconductors, in the hexagonal structure of binary silicides the sp(3) arrangement of silicon atoms leads to corrugated sheets. Th…
Crystal structure of ethylene (E)−tetrafluoroethylene (TFE) alternating copolymer of TFE 50 mol % content has been determined on the basis of 2-dimensional X-ray fiber diagram measured for the uniaxially oriented sample. Different from the unit cell parameters reported previously by several researchers, the newly prop…
This paper presents a numerically efficient approach for simulating nanowires at infrared and long optical wavelengths. A computationally efficient circuit-equivalent modeling approach based on the electric-field integral-equation (EFIE) formulation is employed to simulate the highly dispersive behavior of nanowires a…
Low-temperature specific heat of the monolayer high-${T}_{c}$ superconductor Bi${}_{2}$Sr${}_{2\ensuremath{-}x}$La${}_{x}$CuO${}_{6+\ensuremath{\delta}}$ has been measured close to the optimal doping point ($x~0.4$) in different magnetic fields. The identification of both a ${T}^{2}$ term in zero field and a $\sqrt{H}…
We attempt to solve the magnetic structure of the gadolinium analog of ``spin-ice'' using a mixture of experimental and theoretical assumptions. The eventual predictions are essentially consistent with both the M\"ossbauer and neutron measurements but are unrelated to previous proposals. We find two possible distinct…
A joint experimental and molecular simulation study was performed to investigate the adsorption of tetrachloroethene on two MFI zeolites, ZSM-5 with a Si/Al ratio of 26.5, and silicalite-1, which is the pure silica form of ZSM-5. Adsorption isotherms and isosteric heats of adsorption of tetrachloroethene were measured…
This study explores the solid/liquid phase behavior of mixtures of polycyclic aromatic hydrocarbons (PAHs), exploring the transition from non-ideal solid mixtures to a relatively ideal liquid behavior characteristic of "tars". PAH mixtures have been studied using differential scanning calorimetry, melting point analys…
By applying laser annealing (LA) on both gate dielectrics and source/drain activation, the TaN/ZrO2/La2O3/SiO2on Ge n-MOSFETs shows a high gate capacitance density, a small n+/p-junction ideality factor of 1.10, a small subthreshold swing (SS) of 106 mV/dec, and a good high-field mobility of 285 or 340 cm2/V·s after g…
Abstract Ethylene‐octene copolymer (EOC) was crosslinked by dicumyl peroxide (DCP) at various temperatures (150–200°C). Six concentrations of DCP in range 0.2–0.7 wt % were investigated. cross‐linking was studied by rubber process analyzer (RPA) and by differential scanning calorimetry (DSC). From RPA data analysis re…
A new method is devised to derive a thermodynamic perturbation theory that is suitable for short-ranged potentials. We have calculated structure and thermodynamic of short-ranged square-well potential with good agreement with computer simulation data even at low temperatures. We have also compared the results with oth…
Time-dependent deformation behaviors of closed-cell polyvinyl chloride (PVC) foams (113 and 176 kg/m 3 foam densities) under tension were studied at various strain rates (10 —5 —10 —1 s —1 ). It was found that the tensile properties including modulus, yield strength, ultimate tensile strength, and fracture strain were…
