Surface charge accumulation and decay behaviors of dielectric materials are the key factors restricting the development of high voltage direct current power equipment. For flat samples, the density of surface charges deposited by corona can be regarded as a linear change with the surface potential. For this reason, th…
A number of nanotechnology-enabled drug delivery platforms are in varying stages of drug development. While, physiologically-based pharmacokinetic (PBPK) modelling has become a well-established tool for conventional medicines from preclinical to post-licensing environments, its application for nanomedicines is in its…
Mg is hydrogenated as core-shell type hydride in which the surface is covered with MgH2 (shell) and unreacted Mg remains at the internal side (core). Therefore, increase of absorption capacity to the theoretical hydrogen capacity is still one of the most important issues for the hydrogen storage materials, although se…
Aluminophosphate molecular sieve with LTA topology was efficiently synthesized by seed-assisted and improved ionothermal method with low dosages of organic amines and ionic liquids (ILs). The influences of organic amine type, crystallization temperature, amount of organic species, and seed crystals on the synthesis of…
The structure and mechanical properties of welded joints the of VT23 titanium alloy produced by laser welding with subsequent thermomechanical treatment (TMP1 and TMP2) including ultrasonic mechanical forging are investigated. The results have shown that the fatigue life of welded joints in TMP2 multiply increases com…
Abstract We propose an implicit finite-difference method to study the time evolution of the director field of a nematic liquid crystal under the influence of an electric field with weak anchoring at the boundary. The scheme allows us to study the dynamics of transitions between different director equilibrium states un…
ESI-MS combined with DFT calculation revealed that the vanadium valence state and the vanadium substitution degrees can substantially affect the stabilities of vanadium-substituted POMs.
This paper reports on a solvothermal method used in the fabrication of vertically aligned two-dimensional (2D) ZnO nanowall networks and one-dimensional (1D) ZnO nanorods with overlapping structures. The introduction of an Al thin film as a doping source was shown to alter the morphology from rods to walls. The propos…
This paper describes the fatigue properties of chromium-molybdenum steel in air and diesel oil. 4-point bending fatigue tests were conducted at a stress ratio of R=0.05. The corrosion mark was not confirmed on the specimens tested in diesel oil, and the fatigue strength at Nf < 3×104 improved and that at Nf > 3×104 de…

Представлены результаты исследований по получению электропроводящих гибридных полимерных композиционных материалов на основе нековалентно функционализированных углеродных нанотрубок. Проведены исследования электрофизич…
Different from p -type single-walled carbon nanotubes (SWCNT) thin film transistors (TFTs) with SiO 2 dielectrics, air-stable top-gated n -type SWCNT TFTs are reported with amorphous silicon nitride (SiN x ) dielectrics exhibiting the strong dependence of deposition methods and conditions, and metal contacts. Amorphou…
Thermal-depended conductive properties of the ternary-POM-based layer-structure ionic liquid [TOAMe] <sub>4</sub> [In(H <sub>2</sub> O)PW <sub>11</sub> O <sub>39</sub> ] was investigated. It shows fast ionic conductivity as high as 2.2 × 10 <sup>−3</sup> S cm <sup>−1</sup> at 90 °C with the conductive activation energ…
The present investigation focuses on the preparation of LaNi5 intermetallic compound by ?Metallothermic reduction diffusion process?. Experiments were carried out using oxides and chlorides of La and Ni metal powders as the raw materials with granular Mg powder as the reductant. The thermal reduction process was carri…
Numerous Si nanocrystals on the bulk surface can be efficiently sharpened by a HF-based electrochemical etching with the irradiation of near-infrared (NIR) laser simultaneously. Under the NIR laser-irradiation, the electrons excited from the B-Si complex inhibited the growth of the anodized layer and promoted the form…
Photoelectrochemical properties of ZnO nanorods have been widely investigated due to low cost, easy synthesis process and high carrier mobility. However, weak photoabsorption in visible region is the major bottleneck of ZnO for solar cell applications. To improve the photoelectrochemical behavior, it is necessary to s…

Composite silk fibroin/chitosan nanofiber membrane was fabricated by bubbfil electrospinning. The influence of chitosan content on composite membrane's microstructure, mechanical property, and the percentage of water-dissolved were studied experimentally. The result indicated that the crystallinity of electrospun memb…
Semiconductor (SC) quantum dots (QDs) have recently been fabricated by both chemical and plasma techniques for specific absorption and emission of light. Their optical properties are governed by the size of the QD and the chemistry of any passivation at their surface. Here, we decouple the effects of confinement and p…
Process in which double potassium-ammonium sulfate is produced from potassium chloride and sulfuric acid was studied. A thermal analysis of the compound KNH 4 SO 4 was made and the melting and decomposition points of double potassium-ammonium sulfate were determined. An X-ray phase analysis revealed the processes occu…
The mesomorphic properties of new bent-core mesogens, coupled with the detailed analysis of the molecular packing of the related three-ring compounds is presented.
