The atomic and electronic structures, heat of formation, Young's modulus, and ideal strength of hydrogenated diamond nanowires (DNWs) with different cross-sections (from 0.06 to 2.80 nm(2)) and crystallographic orientations ((100), (110), (111), and (112)) have been investigated by means of first-principles simulation…
Rare-earth-doped glasses are key materials for optical technology due to the luminescent properties of $4{f}^{n}$ ions. The crystal-field model describes the effect of local environment on transitions between $4f$ electrons. We present a detailed modeling study of the optical spectra of sodium disilicate glass, $33{\m…
Optimization of thin films of small bandwidth manganite, Pr(1-x)Ca(x)MnO3 (for x = 0.1), and their magnetic properties are investigated. Using different pulsed laser deposition (PLD) conditions, several films were deposited from the stoichiometric target material on SrTiO3 (001) substrate and their thorough structural…
Detailed kinetic modeling was used to interpret the kinetics of the global CO + O 2 reaction in the presence of hydrogen on Pt/Al 2 O 3, Rh/Al 2 O 3, and Pt/Rh/Al 2 O 3 catalysts. The rate parameters were compiled from the literature and optimized to improve the predictivity against multiple experimental data sets. Th…
The conversion of CO(2) to valuable compounds, which is considered as an effective approach to solve the global warming, represents a great challenge due to the high stability and low reactivity of CO(2). Herein, thermodynamic calculations predicted the feasibility of exothermic reactions between CO(2) and Li(3)N into…
The sol‐gel reaction of tetraethoxysilane in natural rubber (NR) latex was conducted to produce in situ silica‐filled NR latex, followed by adding sulfur cross‐linking reagents to the latex in a liquid state. The latex was cast and subjected to sulfur curing to result in a unique morphology in the NR composite of a fl…
Purpose This paper aims to investigate the galvanic corrosion of titanium/L 316 stainless steel, by electrochemical noise (EN), electrochemical impedance spectroscopy (EIS), and anode/cathode area ratio effect on the galvanic behavior of the couple. Design/methodology/approach The EN measurement was employed to examin…
The main objective of this study was to explore the suitability of Vitis vinifera as a raw material and alkaline lignin as a natural binder for fiberboard manufacturing. In the first step, Vitis vinifera was steam- exploded through a thermo-mechanical vapor process in a batch reactor, and the obtained pulp was dried,…
Abstract The growth of graphene has been carried out on cube‐textured (100) oriented Cu (CTO‐Cu) foils using chemical vapor deposition (CVD). Well‐aligned triangular grains self‐assembled on CTO‐Cu during CVD heating in flowing hydrogen. The nucleation of triangular graphene grains has been confirmed. This demonstrate…
We report on the nonequilibrium quasiparticle dynamics in BaFe${}_{2}$As${}_{2}$ on both the hole-doped (${\text{Ba}}_{1\ensuremath{-}x}{\text{K}}_{x}{\text{Fe}}_{2}{\text{As}}_{2}$) and electron-doped (${\text{BaFe}}_{2\ensuremath{-}y}{\text{Co}}_{y}{\text{As}}_{2}$) sides of the phase diagram using ultrafast pump-pr…
Purpose The purpose of this paper is to study methods of reacting the surface of the particles of silica sols with silanes, primarily gamma‐glycidoxypropyltrimethoxysilane (GPTMS) and study some basic properties of the modified sols and the nature and structure of the silane groups attached to the particle surface. De…
Abstract The mechanical and thermophysical properties of TiO 2 ‐filled chlorobutyl rubber composites were investigated. These materials exhibited enhanced mechanical properties such as increased modulus, tensile strength, and hardness. The morphology of filler dispersion in the matrix was analyzed by scanning electron…
The wood plastic composites (WPCs) are made using matrices of recycled polypropylene with sawdust (pine wood flour) as filler. Corresponding WPCs are also made using virgin plastics (vPP, virgin polypropylene) for comparison with the recycled plastic-based composites. All varieties of these WPCs are made through melt…
The mechanical properties of soft tissues depend on the collagen fiber network and the surrounding non-fibrillar matrix. The mechanical role of non-fibrillar material remains poorly understood. Our recent study (Lake and Barocas, Ann Biomed Eng 2011) introduced collagen-agarose co-gels as a simple experimental model s…
The Fe-vacancy ordering patterns in the superconducting K x Fe 2– y Se 2 and nonsuperconducting K x (Fe,Co) 2– y Se 2 samples have been investigated by electron diffraction and high angle annular dark field scanning transmission electron microscopy. The Fe-vacancy ordering occurs in the ab plane of the parent ThCr 2 S…

Here we report the syntheses and crystal structures of a series of cobalt(II) and nickel(II) complexes derived from (R)NP2 ligands (where R = OMe(Bz), H(Bz), Br(Bz), Ph) bearing ethylene linkers between a single N and two P donors. The Co(II) complexes generally adopt a tetrahedral configuration of general formula [(N…
Fluorescence indicator/layered double hydroxide (LDH) ultrathin films (UTFs) have been fabricated by alternate assembly of 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonate) (ABTS) and Zn–Al LDH nanosheets on quartz substrates using the layer-by-layer (LBL) deposition technique and demonstrated to be good fluorescence…
We demonstrate a purely solvent-based approach to assembling CdSe nanorods into vertically aligned, hexagonally packed monolayers in solution. Nanorods were dispersed in a mixture of good solvent with high vapor pressure and bad solvent with low vapor pressure, and preferential evaporation of the good solvent led to o…
