We report the growth of (001)-textured polycrystalline D022 MnGa films with perpendicular magnetic anisotropy (PMA) on thermally oxidized Si substrates using an (Mg0.2Ti0.8)O (MTO) buffer layer. The ordered D022 MnGa film grown at the optimum substrate temperature of 530 °C on the MTO buffer layer shows PMA with magne…
The nonlinear dynamics of an automotive three-way catalyst (TWC) present a challenge to developing simple control-oriented models that are both useful for control and/or diagnostics and real-time executable within a vehicle engine-control unit (ECU). As such, we begin by developing a first-principles control-oriented…
The aim of this study was to determine the effects of dietary sepiolite on performance, egg quality, egg yolk cholesterol content and some blood parameters of laying hens during 22 weeks period. For this purpose a total of 135 Lohmann Brown laying hens, 38 weeks of age, were allocated to one control group and two trea…
The structural and thermodynamic behavior of a deeply supercooled Lennard-Jones liquid, and its random first-order transition (RFOT) to an ideal glass is investigated, using a system of two weakly coupled replicas and the hypernetted chain integral equation for the pair structure of this symmetric binary system. A sys…
This paper presents a model order reduction (MOR) method for modeling and estimation of a first-principles electrochemical Lithium-ion battery. The MOR approach combines the Galerkin method with coordinate transformation and is applied to solve the spherical diffusion problem with non-zero flux boundary conditions. Th…
Alloy and nitride solid solutions are prominent for structural, energy and information processing applications. There are frequently however barriers to making them. We remove barriers to reactivity here using pressure with a new synthetic approach. We target pressures where the reasons for cubic endmember nitride ins…
The effects of solvent dipolarity/polarizability and solvent-solute hydrogen bonding on the photophysical properties of the antineoplastic drug lomustine were analysed by means of the linear solvation energy relationship (LSER) concept proposed by Kamlet and Taft. The LSER method enabled the overall solvent effects to…
Cu‐ and V‐doped BNKT10‐based piezoelectric ceramics with up to 0.5 at.% dopant concentration were synthesized and displayed more homogeneous grain growth compared to undoped BNKT10 ceramics. The defect chemistry and defect structure, studied by X‐ray photoelectron spectroscopy (XPS) and electron paramagnetic resonance…
Gold (Au) nanoparticles-decorated poly( o-phenylenediamine) (PoPD@Au) hollow microspheres were successfully synthesized by a simple two-step process without any other templates or additives. Scanning electron microscopy, transmission electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, Rama…
Flow-aligned mesoporous silica monoliths incorporating nanometer-sized cylindrical pores serve as models for materials with applications in chemical separations and catalysis. In many such systems, it is assumed that incorporated analytes or reagents are confined to and travel along the one-dimensional (1D) pores. Ani…
Abstract A small library of ureas and related compounds was synthesized and examined by scanning electron microscopy (SEM), single‐crystal X‐ray diffraction, powder X‐ray (pXRD), and polarized optical microscopy (POM) techniques in order to elucidate the factors controlling their self‐assembly in the solid state. Insp…
Zinc-aluminium layered double oxide (Zn-Al-LDO) catalysts derived from layered double hydroxides (LDHs) were prepared and used for the catalytic fast pyrolysis of cellulose to selectively produce 1-hydroxy-3,6dioxabicyclo[3.2.1]octan-2-one (LAC), which is a valuable anhydrosugar derivative. Analytical pyrolysis-gas ch…
Abstract Highly acidic SBA‐15 with different pore diameters has been prepared by functionalizing the mesoporous walls with different amounts of triflic acid (TFA). The structure of the SBA‐15 before and after the functionalization with TFA was investigated by powder X‐ray diffraction and nitrogen adsorption isotherms.…
In this work Y 3 Ga 5 O 12 doped with 8.7 mol% Cr 3+ (YGG:Cr) far-red phosphor pellets calcined at 1000, 1200, 1300, and 1400 °C temperatures were synthesized by a simple and low cost sol–gel method. The YGG:Cr pellets were investigated using X-ray diffraction (XRD) and scanning electron microscopy (SEM) and the lumin…
B 4 C and B 4 C-ZrB 2 (Zr -3-5 wt.%) ceramic materials were obtained by the method of hot pressing at temperature range 2,050-2,140 C and 34-40 MPa pressure, and subject to further thermal treatment at 1,800 C. Physical and mechanical properties of the above composite, the effect of ZrB 2 on the process parameters of…
Multiblock copolymers consisting of poly(ether sulfone) and poly(tetrahydrofuran) (PTHF) as hard and soft segments, respectively, were synthesized by post-polymerization of poly(ether sulfone) and PTHF oligomers via the Williamson ether synthesis. Hydroxy-terminated polysulfone oligomers composed of 4,4′-dihydroxydiph…

The conformations of five doubly neo-confused porphyrin structures and fifty-four neo-confused N-confused porphyrin (neo-C-NCP) tautomers were minimized using DFT-B3LYP/6-311++G(d,p). The relative stabilities of the tautomers for each series were computed using M06-2X and B3LYP-D functionals, and the bond lengths and…
Preforming simulation for structural composite processing can significantly assist in the development of forming tools, prediction of manufacturing issues, optimization of process parameters and structural design analysis. The present study is aimed at investigating the influence of some important parameters in compos…
We present a facile strategy to prepare grape-like silica-based hierarchical porous interlocked microcapsules (HPIMs) by polystyrene colloidal crystals templates, whose structure is the subtle integration of open mouthed structure, hierarchical porous nanostructure and interlocked architecture. HPIMs are fabricated by…
