The TiO2–SiO2 thin films were deposited on AISI 316L stainless steel via sol-gel method. Then, the effect of the added amount of SiO2 on the structure, morphology and mechanical properties of the films and corrosion behavior of AISI 316L stainless steel substrate were investigated. So, X-ray diffraction, field-emissio…
For the advanced tokamak, the particle deposition and thermal load on the divertor is a big challenge. By moving the strike points on divertor target plates, the position of particle deposition and thermal load can be shifted. We could adjust the Poloidal Field (PF) coil current to achieve the strike point position fe…
Recently, in order to make positively use of the effect of adhesive layer, which works as Build-up edge or Belag on the tool surface during machining operation, there have many investigations on the technique to reduce the wear of cutting tool. However, the mechanism of wear on the rake face is unknown and the reason…
High-quality single crystals of A-site ordered perovskite oxides CaCu 3 Ru 4 O 12 were synthesized by flux method with CuO serving as a flux. The typical size of these single crystals was around 1 × 1 × 1 mm 3 and the lattice constant was determined to be 7.430±0.0009 Å by using x-ray single crystal diffraction. The s…
The effect of bean pod particles on the properties of recycled low-density polyethylene (RLDPE) composites was studied. The RLDPE/bean pod particles composites were produced using compounding and c...
Tests were performed on two Carbon-Manganese steels (A42 and A48 steels, French standard) in the gigacycle fatigue domain thanks to a piezoelectric fatigue machine working at 20000Hz. During the tests, temperature recordings were achieved by an infrared camera for various stress amplitudes. The main difference between…
Structural transformations of nanopores with cylindrical shapes in gold under conditions of thermoactivation and the influence of acoustic and shock waves are studied by means of molecular dynamics. It is shown that at temperatures above 600 K, dislocation loops are generated on the inner surfaces of pores, creating s…
Abstract SUMMARY Organisms are made up of thousands of different cell types that must migrate, proliferate, and interact with each other to yield functional organ systems and ultimately a viable organism. A characteristic that distinguishes one cell type from another is the set of genes that it expresses. An article b…
The new complexes [PuO 2 CrO 4 (urea) 3 ] ( 1 ) and [PuO 2 CrO 4 (urea) 2 ] ( 2 ) were isolated from aqueous solutions. Their composition and structure were determined by single crystal X-ray diffraction analysis. Compound 1 has a chain structure, with each Pu atom coordinated by the O atoms of three urea molecules an…
Abstract : A new C++ library for the rapid development of lattice-based kinetic Monte Carlo (kMC) simulation codes, KMCThinFilm, has been introduced. This library implements versions of the Bortz-Kalos-Lebowitz (BKL) algorithm for choosing sequences of random events on a lattice in a kMC simulation, and these implemen…
High absorption efficiency of canonical metal-insulator-metal (MIM) structures have been considered as a desirable feature for various photonic and electronic technological applications, including chemical and biomedical sensors, photodetectors, thermal emitters, and solar cells. However, most of the absorption effici…
Back reflection from grating couplers can be an obstacle to integrate them with isolator-free light sources. A folded shallow-grating coupler is proposed. We numerically confirmed a back reflection of −27 dB while achieving an upward emitting efficiency of −0.58 dB.
There is an increasing use for laminated toroidal cores materials in several applications at different ranges of power rating and magnetising frequencies. Cutting process for the laminations is one of the factor for the power losses increase due to short circuit between layers known as edge burrs. The aim of this pape…
An efficient approach for preparing functional organic field-effect transistors (OFETs) by using spiropyran (SP)-co-methyl metharylate (MMA) as the photoactive gate dielectrics is developed by Xuefeng Guo and co-workers and reported in article number 1500159. SP photoisomerization initiates reversible changes in the d…
This project determined that severe corrosion of steel can occur in the submerged portions of reinforced concrete structures in marine environments. Field studies of decommissioned pilings from Florida bridges revealed multiple instances of strong corrosion localization, showing appreciable local loss of steel cross-s…
The relationship between the microstructure and phase composition of a product obtained by selfpropagating high-temperature synthesis (SHS) and different reaction mechanisms is studied using the example of silicon nitride. The formation of nanosized silicon nitride particles upon the combustion of silicon in nitrogen…
Kenji Hata and co-workers present the key issues to achieve on chip integration of carbon nanotube (CNT) microsupercapacitors with a designable performance in article number 1500741. It is envisioned that this will advance the miniaturization of electronics by replacing bulky aluminum electrolytic capacitors (AECs). T…
The research is devoted to comparison of energy characteristics of linear capacitor and super-capacitor during their charge from the accumulator battery. The features of influence of the final voltages on the electrical energy losses at charge linear capacitors from the accumulator battery and supercapacitors are esta…
An etching-free epitaxial growth method is developed to convert Ag nanostructures of various morphologies into their Ag@Au core/shell counterparts. Anisotropic ones such as nanoplates exhibit excellent plasmonic properties and chemical stability, as shown on page 5435 by C. Gao, Y. Yin and co-workers. As a result, the…
Distributed round-wire windings are usually manufactured using the insertion technology. If the needle winding technology is applied instead the end windings have to be conducted in a three-layer axial arrangement. This leads to differing coil lengths and thus to a phase asymmetry which is much more distinct than the…
