The influence of structural phase transitions, features of electronic structure, and magnetic transformation on the temperature dependence of the heat capacity of LnAO 4 (A = P, V, Nb) compounds has been considered. It has been shown that the sum of the contributions to the thermodynamic functions due to the phase tra…
This article is devoted to the consideration of areas of formation of linear clusters of C−C, C=C, and C−C=C carbon bonds based on a numerical simulation of the plasma arc fusion method. The data on average velocities of carbon ions in plasma for different modes of synthesis of carbon nanostructures are obtained. A si…
Biocompatible and biodegradable polymer microparticles are contemporary medicines able to eliminate the side effects and unsatisfactory pharmacokinetics of already existing preparations. In this work we have developed a high-tech scalable method for the synthesis of paclitaxel-loaded poly(3-hydroxybutyrate) (PHB)-base…
The attenuation coefficients of photon and neutron beams as they pass through the iron–magnetite–serpentinite cement concrete (IMSCC), which is used for biological protection of nuclear reactors, are calculated. Compton scattering makes the main contribution to attenuation of the beam at γ-photon energies lying in the…
Polymer composite formulations for decontamination were developed on the basis of a polyvinyl alcohol solution as a binder with active additives (HNO 3 , HBF 4 , 1-hydroxyethane-1,1-diphosphonic acid and its triammonium salt, and a synthetic detergent) and fillers (natural rottenstone; rottenstone modified with nickel…
The high-temperature superelasticity and temperature dependence of the yield stress of 14M and L1 0 martensite in [001]-oriented single crystals of Ni 54 Fe 19 Ga 27 (at %) in compression alloy have been studied. As the temperature increases, the sequence of stress-induced martensitic transformations (MTs) changes fro…
Research of Trap and Electron Density Distributions in the Interface of Polyimide/Al2O3 Nanocomposite Films Based on IDC and SAXS* , Liu, Yuan-Yuan, Yin, Jing-Hua, Liu, Xiao-Xu, Sun, Duo, Chen, Ming-Hua, Wu, Zhong-Hua, Su, Bo
It has been shown that, in a uniaxial paramagnet with non-Kramers ions with a spin of S = 1 and single-ion anisotropy of the easy-plane type (DS 2 ), there is a low-field (μ0 H ≤ D) and low-temperature (k B T < 0.68D) region in which the isothermal magnetization along the hard direction H||OZ increases the magnetic en…
Gold nanoparticles (NPs) with the average core diameter d Au = 6.8 ± 1.6 nm have been synthesized in reverse micelles of the oxyethylated surfactant Brij 30. It has been shown that thin NP films can be produced directly from a micellar solution with the use of glass substrates functionalized with aminosilane. Synthesi…
This study aims to restrain free conducting wire-type particles which are commonly and dangerously existing within DC gas-insulated transmission lines. A realistic platform of a coaxial cylindrical electrode was established by using a high-speed camera and a partial discharge (PD) monitor to observe the motion, PD, an…
The adsorption and dissociation of O2 on the M4 (M=Au, Pd, Pt) clusters supported on HfC(001) (Hafnium Carbide) are investigated using ab initio density functional theory calculations. The geometric and electronic structures are analyzed in detail. It is found that the dissociation barriers of O2 on Au4/HfC(001) (0.26…
PEDOT:PSS suffers from its poor structural homogeneity. In article number 1601499, Yuan Li, Xueqing Qiu, Hin-Lap Yip, and co-workers report a novel PEDOT:MNSF with enhanced structural homogeneity and promising performance in organic electronic devices. The branched structure of PEDOT:MNSF contributes to its hole extra…
Crystallinity and field electron emission characteristics of few-layer graphene (FLG) have been investigated synchronously by using in situ transmission electron microscope (TEM) to reveal their relationship. The crystallinity of a single FLG sheet is modified from polycrystalline to amorphous by TEM electron beam irr…
Water recovery and subsequent reuse are required for human consumption as well as industrial, and agriculture applications. Moist air streams, such as cooling tower plumes and fog, represent opportunities for water harvesting. In this work, we investigate a flapping mechanism to increase droplet shedding on thin, hydr…
The influence of Y2O3 nanolayers on thermoelectric performance and structure of 2% Al-doped ZnO (AZO) thin films has been studied. Multilayers based on five 50 nm thick AZO layers alternated with few nanometers thick Y2O3 layers were prepared by pulsed laser deposition on Al2O3 single crystals by alternate ablation of…
Both in research and in the light of industrial applications, there is a growing interest in methods to characterize the mechanical behavior of materials at high strain rates. This is particularly true for steels (the most important structural materials), where often the strain rate-dependent material behavior also ne…
The degradability and clearance of siliceous nanomaterials have been questioned worldwide since they are crucial prerequisites for successful translation in the clinic. In article number 1604634, Niveen M. Khashab and co-workers summarize the degradability and clearance of silicon and mesoporous silica nanoparticles,…
The degassing of 09Г2C steel produced in an arc furnace and treated in a ladle–furnace unit at AO Uralskaya Stal is analyzed. The vacuum-treatment parameters that determine the effectiveness of hydrogen removal from the steel are identified: the depth and duration of vacuum treatment; the argon flow rate; the steel te…
We apply the contact-end resistance method to TLM structures in order to characterize the graphene-metal contact resistance. A critical analysis of the experimental results shows that the commonly used transmission line model fails to accurately describe the graphene-metal contact under specific biasing conditions. Th…
Results are reported of a study of the structural and electrical characteristics of substituted bismuth niobates with composition Bi3Nb1–x Er x O7–δ, which are promising oxygen-ion conductors. The homogeneity regions of solid solutions were determined by X-ray phase analysis and electron microscopy with X-ray fluoresc…
