The spin valve effect for the superconducting current based on the superconductor/ferromagnet proximity effect has been studied for a CoO x /Fe1/Cu/Fe2/Cu/Pb multilayer. The magnitude of the effect ΔT c = T AP − T P , where T P and T AP are the superconducting transition temperatures for the parallel (P) and antiparal…
The structural, elastic, and electronic properties of zirconium nitride (ZrN) and hafnium nitride (HfN) are investigated by first principles calculation with density functional theory. The obtained cubic NaCl structure is energetically the most stable structure at ambient pressure. A pressure induced structural phase…
The paper describes the basic problems regarding the possibility of using waste plastics and tire rubber waste as raw materials for the preparation of liquid energy carriers for transport (WtL processes) or directly to energy use in a WtE. Simultaneous measurements were performed at Thermal Analyzer STA 449 F3 Jupiter…
This paper describes two stages of optimization of the properties of 2024 and 7075 aluminium alloys, in particular their resistance to pitting by first T6, T6I6 or T6I4 treatment, and second increase its tribological properties by depositing by RF PACVD method a gradient coating of high adhesion to the substrate. Quan…
The adsorption behaviors and mechanism of geopolymers based on metakaolin-fly ash for Sr2+, Co2+ and Cs+ were investigated in static method. The results showed that the geopolymer has a strong adsorbability for Sr2+, Co2+ and Cs+ and the adsorbances are mainly affected by ion concentration and pH value of the solution…
Abstract Although typical organic molecules are simply composed of carbon (C), hydrogen (H), nitrogen (N) and oxygen (O) atoms, their unique bonding manners based on sp 3 , sp 2 and sp hybrid orbitals enables very sophisticated molecular architectures, leading to unique functions. By using unlimited freedom of molecul…
Methane conversion has been studied using gliding arc plasma in the presence of argon. The process was conducted at atmospheric pressure and ambient temperature. The focus of this research was to develop a process of converting methane to C 2 hydrocarbons and hydrogen. The main parameters, including the CH 4 /Ar mole…
The resonance fluorescence spectrum of an atom located in the near field of a plasmonic nanoparticle is considered. It is shown that, as the atom gets close to the nanoparticle, the high-frequency peak of the Mollow triplet disappears and the spectrum has a Fano resonance shape. The low-frequency peak also disappears…
Although characterization of hydrogen (H) in silicon (Si) is of interest from a device physics viewpoint, this is difficult using conventional analytical methods. In this study, deuterium (D) was used as a proxy for H, and the distribution of implanted D-ions in Si(100) was investigated using atom probe tomography (AP…
A rapid curing resin system made from the diglycidyl ether of bisphenol A epoxy, modified imidazole and modified aliphatic amine was developed. The curing behaviour and following characteristic of the resin were evaluated by differential scanning calorimetric and rheological analysis, respectively. Carbon fibre-reinfo…
Many chronic brain implants would benefit from a neural probe with many densely configured electrodes with stable recording quality. We present a novel strategy to scale up the number of electrodes with minimized risk of proportionally increasing the adverse foreign body reactions. A flexible parylene probe having 64…
A wide range of injuries could affect the bladder and lead to eventual loss of its integrity, with the need for replacement or repair. Augmentation ileocystoplasty is considered till now the gold standard option for bladder replacement, despite its associated complications. Bladder tissue engineering appears as an app…
Tension tests were carried out to investigate the effect of the corrosion pattern on the ductility of tension bars extracted from a 26-year-old corroded reinforced concrete beam. The tensile behavior of corroded bars with different corrosion patterns was examined carefully, as were two non-corroded bars extracted from…
TiO 2 thin films were prepared on Pt/Ti/SiO 2 /Si substrate by laser chemical vapor deposition (LCVD) method. The effects of laser power ( P L ) and total pressure ( p tot ) on the microstructure of TiO 2 thin films were investigated. The deposition temperature ( T dep ) was mainly affected by P L , increasing with P…
Antiproliferative drugs such as sirolimus (SIR) and paclitaxel (PAT) are currently released from stents and vascular grafts to inhibit the growth of smooth muscle cells (SMCs), thereby preventing neointimal hyperplasia. However, these drugs delay or impair the growth of endothelial cells (ECs) on implant surfaces caus…
ITER is a representative prototype of a fusion power plant. It contains most of the features and systems that are anticipated in a fusion reactor and will produce substantial fusion power (500 MW) for long periods of time (100's of seconds). Therefore its electrical power loads are generally representative of those wh…
ZnO nanoparticles Synthesized by precipitating Zinc Chloride have been characterized Optically and Structurally. XRD is used for the structural characterization where the lattice constant was determined as a=b=3.2492A, c=5.20661 A with hexagonal structure and crystallite size as~5.3689 . UV-vis spectrometer was used t…
This paper presents an overview of the growth of Bi 2 Se 3 , a prototypical three-dimensional topological insulator, by molecular-beam epitaxy on various substrates. Comparison is made between the growth of Bi 2 Se 3 (111) on van der Waals (vdW) and non-vdW substrates, with attention paid to twin suppression and strai…
Abstract Particles of the perovskite material CaMn0.875Ti0.125O3−δ have been examined as an oxygen‐carrier material for chemical‐looping with oxygen uncoupling (CLOU). The aim of the work has been to determine the effect of the fuel‐to‐bed mass ratio for oxidizing solid fuels, and to determine the influence of SO2 on…
The new complexes [M(BHBDAE)(H2O)2] (Co(II), Ni(II), Cu(II) and Zn(II); BHBDAE: N,N'-bis(2–hydroxybenzylidene)–1,1–diaminoethane) have been synthesized and characterized by IR, EPR, 1H NMR, magnetic moment as well as electronic spectroscopy data. The stepwise formation of the complexes has been established in the pH r…
