Ambrinoite, ideally (K,NH 4 ) 2 (As,Sb) 8 S 13 ·H 2 O, occurs as a rare sulfosalt species in the Triassic evaporitic formation of Gessi (gypsum) outcropping near the hamlet of Signols (Oulx, Susa Valley, Torino, Piedmont, Italy). The new species is associated with sulfur and orpiment; in the same occurrence galkhaite,…
Different types of electronic transitions and the corresponding spectral characteristics of the absorption coefficient of amorphous semiconductors, where the energy of absorbed photons exceeds the mobility band gap, have been investigated. Partial spectral characteristics of the absorption coefficient and, correspondi…
In this study Ru-Mn alloys are discussed in terms of some of the major questions that are typically associated with the development of new types of barriers. First, the Cu diffusion barrier performance after annealing at high temperatures and under subsequent bias temperature stress is investigated, on SiO2and on low-…
The paper deals with the partial results of the project specialized in innovation of research in magnetic lenses and chambers of electron microscopes. The paper is aimed at the simulation of magnetic field distribution of some types of magnetic lenses in software Ansys with the employment of results of magnetic measur…
Thermoelectric properties of Sr-doped LaCoO3 system which includes both La1−xSrxCoO3 and La0.95−xSrx0.05CoO3 containing the A-site vacancy were prepared by solid state reaction. The crystal phases of the samples were investigated by X-ray diffraction method. The electrical conductivity, Seebeck coefficient, and therma…
In a recent study, low-k thin films with low dielectric constant (≤2.1) and high Young's modulus (>5 GPa) were obtained by introducing a remote plasma step between the traditional plasma enhanced chemical vapour deposition and UV curing. This study shows that the UV curing step with a narrow band lamp with wavelength…
We have already considered the problem of joint work of structure, foundation slab and basis in [1, 2] (two-layer beam or slab on elastic basis). The distinctive paper is devoted to analysis of two-layer beam-strip on elastic basis, which corresponds to the problem of the plane deformed state. Nonlinear dependence of…
The Cu(SnN x ) alloy film formed in this study by doping a minute amount of Sn or SnN in a copper film via barrier-free Cu metallization method exhibits a good stability at high temperatures, an apparent improvement in adhesion and a greater electrical reliability, including low resistivity, lower leakage current in C…
The feasibility of determining the elemental composition, chemical state, and element distribution across the depth in a subsurface region using the computer simulation of the electron inelastic scattering cross section is demonstrated with iron layers on silicon substrates. Analysis is carried out based on the dielec…
Application of seven different azoles namely; 1H-Pyrazole-3,5-diamine (azole 1), 1-Benzoyl benzotriazole (azole 2), 1-P-Chloro-Benzoyl benzotriazole (azole3), 1-P-Methoxy-Benzoyl benzotriazole (azole 4), 4-Phenyl-1H-pyrazole-3,5-diamine (azole5), N-[Benzotriazol-1-yl-(phenyl)-methylene]-N’-phenyl-hadrazine and 2-pheny…
Nano-sized silver particles at a concentration of 1620 ppm were prepared using hydroxypropyl starch (HPS) as a reductant of silver nitrate and a stabilizer for silver nanoparticles. A solution containing 1620 ppm silver nanoparticles was diluted to 50 ppm and 100 ppm. The diluted solution was applied to cotton fabrics…
Natural dye (Sambucus nigra, whose common name is elder) is used to dye silk fabric. The dyed fabric samples have been post mordanted with three different mordants, including alum; ferrous and chrome. A thermo-gravimetric analysis (TGA) and differential scanning colorimetry (DSC) of all the samples are used to investi…
Partial discharge in transformer can be detected and localized on-line using UHF technique. The first step for achieving this goal particularly the PD localizing is creation of simulation environment. In this paper three dimensional simulation is done using the FDTD method. The created simulation environment by FDTD w…
The integration of Carbon Nanotubes (CNT) in contact holes with TiN underlayer using CMOS compatible processes is discussed. Each process step was optimized by evaluating the electrical results obtained with contact test structures. Subsequently, this process was transferred to 150 nm diameter contact holes. We presen…
Liquid crystal devices are increasingly used as an alternative to mechanical systems in free-space beam steering and handling as they have no movable components and can be controlled by low voltages.
We present the first single-crystal Raman spectra of the mineral schafarzikite FeSb 2 O 4 from the Pernek locality of the Slovak Republic. In addition, Raman spectra of the natural mineral apuanite Fe 2+ Fe 4 3+ Sb 4 O 12 S, originating from the Apuan Alps in Italy, as well as spectra of synthetic ZnSb 2 O 4 and the a…
High-purity and homogeneous powders of CeB6 with nanometer size were prepared by combustion synthesis and subsequent acid- leaching. The effects of reactant ratio on the phase and morphology of the combustion product were discussed. The combustion product and leached product were analyzed by XRD, SEM and EDS. The resu…
Mn-doped BiFeO3 (BFMO) films were deposited on Pt(111), SrRuO3(SRO)/Pt(111) and LaNiO3(LNO)/Pt(111) bottom electrodes by radio-frequency (RF) sputtering. <111> and <100>-oriented BFMO films were formed on the SRO/Pt and LNO/Pt bottom electrodes, respectively. The remanent polarization (P r) in a <111>-oriented BFMO fi…
Measurement of Three-Dimensional Magnetostriction on Grain-Oriented Electrical Steel Sheet This paper deals with the magnetostriction of a grain-oriented electrical steel sheet measured by using the two-dimensional vector magnetic property measurement system and a three-axial strain gage. The magnetostrictions in arbi…
Solid Oxide Fuel Cells (SOFCs) are of great interest due to their high energy efficiency, low emission level, and multiple fuel utilization. SOFC can operate with various kinds of fuels such as natural gas, carbon monoxide, methanol, ethanol, and hydrocarbon compounds, and they are becoming one of the main competitors…
