Monoclinic β-Ga2O3field effect transistors (FETs) have been recently explored for power electronics application [1, 2] due to its large bandgap, and the availability of native substrates. Quantitative impact ionization coefficient (α) values are required to accurately predict the achievable breakdown voltages in these…
In this paper, at first the term and the technical significance of the degree of polymerization (DP) of cellulose insulation is explained. Factors influencing the DP of new, unused insulation products are detailed. An overview of commonly used DP measuring techniques and standards is given. Depending on the method, th…
Abstract Quantum dots are showing commercial promise for achieving wide color gamuts in LCD displays when used to generate the red and green portions of the spectrum. To date these have been incorporated using a separate optical element or a large‐area film. We instead describe a drop‐in, on‐chip solution to QD‐based…
The experiments proved that during a thermal runaway, hydrogen is evolved from sealed nickelcadmium batteries in amount approximately ten times less than from unsealed batteries of the same capacity equipped with electrodes of the same type. Besides, the electrodes of the sealed nickelcadmium batteries with a long ope…
In this work thin film samples of 300 nm thickness with composition ZnAlO were deposited on glass substrate by DC sputtering technique. The effect of the atmosphere gas contents during sputtering was studied by using Ar for some of the prepared samples and Ar+O2 mixture for the others. Additional investigations were a…
Process of formation and coarsening of sulfur nanoparticles deposited from aqueous solutions of calcium and sodium polysulfides and sodium thiosulfate and from solutions of elementary sulfur in a mixture of hydrazine hydrate and monoethanolamine was considered. The sulfur nanoparticles were characterized with a laser…
Transparent armor consists of glass-polymer laminates in most cases. The formation and propagation of damage in the different glass layers has a strong influence on the ballistic resistance of such laminates. In order to clarify the course of events during projectile penetration, an experimental technique was develope…
Successful validation of the dielectric design of high temperature superconducting DC cables cooled with pressurized helium gas circulation is reported. The dielectric design features were developed based on the tests of several short sample cables. The features were adapted for the dielectric design of the cable and…
Hydrogels from self-assembling ionic complementary peptides have been receiving much interest from the scientific community as mimetics of the extracellular matrix that can offer three-dimensional support for cell growth or become vehicles for the delivery of stem cells or drugs. These scaffolds have also been propose…
Abstract Three new valleriite-group minerals, ekplexite (Nb,Mo)S2·(Mg1−xAlx)(OH)2+x, kaskasite (Mo,Nb)S2·(Mg1−xAlx)(OH)2+x and manganokaskasite (Mo,Nb)S2·(Mn1−xAlx)(OH)2+x are found at Mt Kaskasnyunchorr, Khibiny alkaline complex, Kola Peninsula, Russia. They occur in fenite consisting of orthoclase−anorthoclase and n…
This paper investigates the sewability of the woven denim fabrics based on needle penetration force (NPF). For this purpose, the effects of fabric weight, number of fabric layers, needle size, and the interaction effect of these parameters on NPF in twill denim fabrics were investigated. In addition, the influence of…
Reinforced natural rubber (NR) nanocomposites were prepared by solution mixing. casting. and evaporation of pre-vulcanized natural rubber latex and an aqueous suspension of cellulose nanofibrils (CNFs) extracted from bleached eucalyptus kraft pulp. Scanning electron microscopy (SEM) images showed that there were no mi…
Carbon nanotube having exceptional material properties gained substantial interest as superior reinforcing phase over conventional microscopic fillers in making advanced nanocomposites for high performance applications. Present review sequentially describes pro- cessing of some novel carbon nanotube/alumina nanocompos…
In this paper the statistical analysis for the causes of outdoor insulation accidents of AC and DC high-voltage transmission lines in China were described. This paper focuses on lightning strike, pollution flashover, icing, birds-caused damage, and other factors which may damage the safe operation of power transmissio…
BACKGROUND: We characterize a novel nanocomposite that acts as an efficient anticancer agent. METHODS: This nanocomposite consists of zinc layered hydroxide intercalated with protocatechuate (an anionic form of protocatechuic acid), that has been synthesized using a direct method with zinc oxide and protocatechuic aci…
The effect of cryorolling (CR) strain at 153 K on the evolution of structural defects and their interaction in α−brass (Cu–30 wt.% Zn) during nanostructuring has been evaluated. Even though the lattice strain increases up to 2.1 × 10−3 at CR strain of 0.6 initially, but it remains constant upon further rolling. Wherea…
We have studied Raman scattering in yttria nanopowders and ceramics that was excited by radiation at wavelengths of 514.5 and 632.8 nm. We show that, in undoped nanopowders and cubic phase of doped yttria ceramics, only the Raman scattering by phonons is observed, with no other Raman scattering centers having been rev…
Spatial orientation of carbohydrates is a meaningful parameter in carbohydrate recognition processes. To vary orientation of sugars with temporal and spatial resolution, photosensitive glycoconjugates with favorable photochromic properties appear to be opportune. Here, a series of azobenzene glycosides were synthesize…
Tumor growth depends on angiogenesis, which can furnish the oxygen and nutrients that proliferate tumor cells. Thus, blocking angiogenesis can be an effective strategy to inhibit tumor growth. In this work, three typical nanoparticles based on polyoxometalates (POMs) have been prepared; we investigated their capabilit…
This paper presents an experimental study of the compression behavior of a typical warp-knitted spacer fabric which is specially developed as a cushioning material for human body protection. The fabric has a highly heterogeneous and discontinuous structure and exhibits a complicated compression behavior. Different tes…
