With the urbanization thriving in China, electric cables are gradually replacing the overhead line and widely used in urban distribution grid. Meanwhile, fault rate of electric cables has increased in recent years. Owing to the harsh environment the electric cables worked at, most of them experienced high humidity, ev…
The present study was carried out to investigate the potential of carboxylate group functionalized Multi-walled carbon nanotubes (MWCNT−COOH) adsorbent for the removal of Methyl orange (MO) textile dye from aqueous solutions. The effects of pH, shaking time and temperature on adsorption capacity were studied; the cont…
Resonance optical effects in ordered two-dimensional arrays of gold nanodisks embedded in an insulating magnetic film are investigated. The angle-resolved transmission spectra exhibit features related to the excitation of local surface plasmons and lattice plasmon polaritons in the gold nanoparticles and waveguide mod…
We report on an advanced in-situ electron-beam lithography technique based on high-resolution cathodoluminescence (CL) spectroscopy at low temperatures. The technique has been developed for the deterministic fabrication and quantitative evaluation of nanophotonic structures. It is of particular interest for the realiz…
Coupling diffusion process of signaling molecules with nonlinear interactions of intracellular processes and cellular growth/transformation leads to a system of reaction-diffusion equations coupled with ordinary differential equations (diffusion-ODE models), which differ from the usual reaction-diffusion systems. One…
Abstract. We study the propagation of an unusual type of periodic travelling waves in chains of identical beads interacting via Hertz’s contact forces. Each bead periodically undergoes a compression phase followed by a free flight, due to special properties of Hertzian interactions (fully nonlinear under compression a…
The paper develops an approach to formulation of constitutive equations for predicting the microstructure formation in a thin material layer near surfaces with high friction stresses in material forming processes. The approach is based on the use of the strain rate intensity factor. An equation relating the layer thic…
Strong correlation between Jc(T, H||c) and Jc(77 K, 3 T||c) in Zr-added (Gd, Y)BaCuO coated conductors at temperatures from 77 down to 20 K and fields up to 9 T, Xu, A, Delgado, L, Heydari Gharahcheshmeh, M, Khatri, N, Liu, Y, Selvamanickam, V
A template-free sol-gel synthesis method has been developed for obtaining mesoporous alumino-silicates with a narrow pore size distribution. The effect of the synthesis conditions on the formation of the porous structure and on the phase composition and surface acidity of the aluminosilicates has been elucidated. The…
Ab initio calculations on CsSnX3 perovskites and mixed halides CsSn(XxY 1−x)3, X and Y = I, Cl, and Br, show that all of them have a direct band gap of ∼1 eV which can be tuned by varying the compositions of X and Y. The optimized supercells are tetragonal, orthorhombic or monoclinic. The top of the valence band arise…
Enhancement of mechanical and wear-resistant properties of polymer composites is important because they are widely used in tribological environments. The properties can be enhanced by reinforcement with particulates in the polymer matrix. Nylon is used in many engineering applications, and silica fume is used as a fil…
Eggplant has a very limited shelf life and, like other vegetables, is susceptible to different types of damage during and after harvest operations. Besides, eggplant is inhomogeneous considering its inner construction point of view. It is therefore important to specify how storage might affect their mechanical propert…
The structures of transition states and activation parameters of radical addition of tBuOO• and Ph(CH3)2COO• to the C60 and C70 fullerenes have been found by density functional theory method PBE/3ζ. Calculated by Eyring equation, the rate constants of the tBuOO• addition to C60 and C70, equal to 100 and 18.9 L mol−1 s…
The main chromophore of (6-4) photoproducts, namely, 5-methyl-2-pyrimidone (Pyo), is an artificial noncanonical nucleobase. This chromophore has recently been reported as a potential photosensitizer that induces triplet damage in thymine DNA. In this study, we investigate the spectroscopic properties of the Pyo unit e…
Rhamnogalacturonans I are complex pectin polysaccharides extremely variable in structure and properties and widely represented in various sources. The complexity and diversity of the structure of rhamnogalacturonans I are the reasons for the limited information about the properties and supramolecular organization of t…
ZnO nanorods are passivated with a TiO 2 interfacial layer prepared by the atomic layer deposition method and applied in the CH 3 NH 3 PbI 3 perovskite solar cell, which show a positive effect on the fill factor and power conversion efficiency. With TiO 2 interfacial passivation, the charge recombination in the ZnO/CH…
We have studied the speciation of carbon monoxide in both Fe-bearing and Fe-free basaltic glasses using Raman, FTIR, and Mössbauer spectroscopy. We show that a band at 2110 cm -1 in the Raman spectrum and another band at 2210 cm -1 in the FTIR spectrum occur both in the Fe-bearing and Fe-free samples, implying that th…
The performance of a multi-chamber microbial fuel cell (MFC) was investigated that consisting of four anodes and a cathode component separated by a membrane. The arrangements of the anode and cathode chambers were similar to four individual MFCs stack connected electrically in parallel fashion by sharing a cathode cha…
The natural antioxidants of food products have great influence on human health. Indeed, the protective effects against cardiovascular diseases, cancer and ageing have been attributed to their polyphenol content. In turn, the remarkable antioxidant activity of polyphenols can be easily estimated by polyphenol oxidases…
Cd5Se95-xZnx (x = 0, 2, 4, 6) chalcogenide semiconductors were prepared by conventional melt-quenching and were characterized by X-ray diraction, scanning electron microscopy, and Fourier transform infrared studies. Ac conductivity of Cd5Se95-xZnx chalcogenide semiconductor has been investigated in the frequency range…
