Electro-optical response of a current-carrying monolayer graphene is studied theoretically. Our calculation takes into account full (diagonal and nondiagonal) conductivity tensor obtained from a particle-conserving out-of-equilibrium distribution function of doped graphene. Our analytical and numerical results indicat…
To address the difficulty of joining polystyrene (PS) and titanium by laser transmission joining, two methods-laser treatment of the titanium surface and oxygen plasma treatment of the PS surface-are used to compare the laser transmission joint strengths of the different treatment methods. The results of the experimen…
Micro-tensile tests were conducted on reduced-activation ferritic steel F82H specimens after irradiation with Fe and He ions. The displacement damage levels were 50 and 200 dpa, and helium concentrations were 0, 2000 and 5000 appm. The specimens had dimensions of 8 × 1 × 1 µm for the gage section and they were tension…
Electrokinetic phenomena in a nematic suspension are considered when one or more dielectric particles are suspended in a liquid crystal matrix in its nematic phase. The long-range orientational order of the nematic constitutes a fluid with anisotropic properties. This anisotropy enables charge separation in the bulk u…
Herein we demonstrate that the photolabile protecting group (PPG), the 1-[3-(diethylamino)-phenyl]ethyl (DEAPE) group, has dramatically different photochemical properties from the parent 3-(diethylamino)benzyl (DEABn) PPG. The new PPG, derived from DEABn by adding a methyl group to the benzylic carbon, has similar rea…
Active nanocomposites are created with liquid inclusions that contain plasmonic gold nanoparticles inside a polymeric matrix. The alkylthiol-coated gold particles are designed to reversible agglomerate at certain temperatures, which changes the plasmonic coupling and thus optical properties. It is found that particles…
This work focused on the development of the phase equilibria models required to describe the behavior of mixtures involved in the synthesis of tributyl citrate (TBC) via esterification of citric acid (CA) and butan-1-ol (BuOH). Vapor–liquid equilibrium (VLE) for the mixture TBC–BuOH, liquid–liquid equilibrium (LLE) fo…
Oxygen solid solution has been well known to have a high hardening effect on Ti and its alloys, while it also imposes a serious embrittlement behavior. This study investigated the effect of a rapid cooling process by water quenching (WQ) after heat treatment on the microstructures and mechanical properties of powder m…
Actually, many discussions on the potential risks of silver nanoparticles (AgNPs) have been reported; however, unfortunately, very few considered the great differences between the nature of silver and sources of their syntheses. All data suggested that the effects on toxicity of AgNPs are related to the combination of…
Abstract The stacking effects on the electronic structure of van der Waals heterostructures consisting of silicene and hexagonal boron nitride are investigated by first‐principles calculations. It is shown that the stacking is fundamental for the details of the dispersion relation in the vicinity of the Fermi energy (…
An investigation was carried out into the instability of the crystal/melt interface in Si-rich SiGe, and the effects of the Ge concentration and growth velocity on the periodicity of zigzag facets at the interface were determined. It was found that the periodicity at the onset of instability became shorter with the in…
Bi-phase dispersible (dispersible both in organic and aqueous medium) Fe3O4@Au core-shell multifunctional nanoparticles were synthesized by a modified nanoemulsion process. The formation of the core-shell multifunctional nanostructure was accomplished with the assistance of poly(ethylene glycol)-block-poly(propylene g…
The preparation of high-density lead-free potassium-bismuth titanate K0.5Bi0.5TiO3 about 96–98% of the calculated density (X-ray), confirmed by the Archimedes method, is presented. All stages of the technological process are explained in detail. The control of microstructure was performed by scanning electron microsco…
ABSTRACT In this paper, a chitosan (CS)/glycerol (GL) composite film was prepared, and the solution‐responsive feature of the composite film in a mixed water/ethanol solution was investigated. The composite film began to show obvious shape recovery behavior when the water content of the mixed solution was more than 50…
A hybrid nanocomposites containing nanocrystalline TiO2 and graphene-related materials (graphene oxide or reduced graphene oxide) were successfully prepared by mechanical mixing and the hydrothermal method in the high-pressure atmosphere. The presented X-ray photoelectron spectroscopy (XPS) study and quantitative elem…
Woven fabrics made of a natural lignocellulosic mallow fiber have been used for a long time in common clothes. Recently, these fabrics are being considered as reinforcement for engineering composites. This work investigates the basic mechanical behavior of polyester composites reinforced with up to 40 vol% of mallow f…
High-pressure resistant and multidirectional compressible materials enable various applications but are often hindered by structure-derived collapse and weak elasticity. Here, a super-robust graphene foam with ladder shape microstructure capable of withstanding high pressure is presented. The multioriented ladder arra…
Ceramic materials have a long-term industrial demand due to their high mechanical hardness and chemical and temperature resistance. They are brittle and tend to lose strength under heavy loads which complicates the development of a comprehensive material model for simulation of engineering prototypes containing cerami…
Stator insulations comprised of mica-filled epoxy glass composite materials are of paramount importance for the reliability of high-voltage rotating machines. The present work deals with the fracture mechanical characterization of the winding insulation under conditions of monotonic and cyclic loading. The identificat…
