The prediction of corrosion damage to times that are experimentally inaccessible by a large factor (e.g. to over 1000 years) is vitally important in assessing various concepts for the disposal of high level nuclear waste. Such prediction can only be made using deterministic models, whose predictions are constrained to…
The gate-induced band-to-band tunneling in carbon nanotube field effect transistors (CNFETs) is studied by solving the Poissson and carrier transport equations self-consistently. The transmission coefficient through the bandgap has been calculated using the Wentzel–Kramers–Brillouin (WKB) approximation. The device par…
Single crystalline zinc oxide (ZnO) nanorods have been grown on Si (100) substrates by a hydrothermal method at 65 °C. In order to show the habit of crystalline growth and applied these ZnO 1D to the electron radiation. The ZnO nanorods grown on Si (100) have been characterized in detail using X-ray diffraction (XRD)…
Carbon films were deposited in a filtered cathodic vacuum arc with a bias potential applied to a conducting mesh mounted in the plasma stream between the source and the substrate. We determined the stress and microstructural properties of the resulting carbon films and compared the results with those obtained using di…
We have developed a novel method for fabrication of a PEDOT nanofiber-based glucose biosensor on the surface of platinum microelectrodes. Glucose oxidase was immobilized into PEDOT nanofibers during the polymerization process. We have demonstrated that glucose could be detected at a low potential of +300mV versus Ag/A…
Porous cordierite ceramics with well-distributed interconnected pores were prepared by pore forming in situ technique coordinated with adding pore forming agent. The phase, microstructure, strength and gas permeability were investigated through X-ray diffractometer, scanning electron microscopy, mercury porosimetry me…
The analysis of theoretical published data and our experimental data makes it possible to assume that the main difference between polyacrylonitriles prepared via emulsion and solution polymerization appears at the stage of synthesis. This difference is likely related to the freezing of the segmental mobility of strong…

We modify optical and wetting properties of solids using a femtosecond laser surface nanostructuring technique. We demonstrate that this technique allows creating black and color metals. Absorptance of black titanium created in our study is measured to be about 90-97% over a broad wavelength range from the ultraviolet…
The human heat-moisture-comfort level is mainly determined by heat and moisture transfer characteristics in clothing. With respect to the model of steady-state heat and moisture transfer through parallel pore textiles, we propose an inverse problem of thickness design for bilayer textile material under low temperature…
It is thought that antimicrobial resistance imposes a fitness cost on bacteria, so that a reduction in antimicrobial use may reduce the incidence of resistant bacteria. The objectives of the present study were to determine (1) whether multidrug resistant (MDR) Escherichia coli field strains with different plasmid prof…
The inverse spinel ferrimagnets CoFe 2 O 4 (CFO) and NiFe 2 O 4 (NFO) are of interest for applications in spin-filter devices or as building blocks of artificial multiferroic heterostructures. Here we present density functional theory calculations of the structural and magnetic properties of CFO and NFO, with special…
The effects of Er 2 O 3 (0–8 mol%) doping and Er 2 O 3 and Yb 2 O 3 codoping (total 1–7 mol%) on the absorption cross‐section, PL, and upconversion intensities of the SnO–P 2 O 5 glass have been investigated. Precipitation of ErPO 4 and the (Yb, Er)PO 4 crystalline phase in the SnO–P 2 O 5 glass matrix when the total…
Oxide based two phase composite electrolyte (Ce0.9Gd0.1O2–Y2O3) was synthesized by coprecipitation method. The nanocomposite electrolyte showed the significant performance of power density 785 mW cm−2 and higher conductivities at relatively low temperature 550°C. Ionic conductivities were measured with ac impedance sp…

In this study, on the basis of simulation of the electric field, the design optimization methods for 120 and 250 kA magnesium electrolysis cells were developed. A 3D numerical model was built to simulate the electric field at the steady state to obtain the minimum resistance voltage which has a significant effect on t…
The measurements of the corrosion potential and the analysis of the polarization characteristics revealed that titanium VT1-0 with a nano- and submicrograin structure exhibits higher electrochemical activity in a 0.9% NaCl solution than its macrograin analogs. The formation of anode oxide films on the surface of titan…
The complete evolution of holmium-laser-pulse-induced cavitation bubble movements and acoustic transients underwater are investigated experimentally. The laser was single fiber-guided and had a 300 mJ pulse energy and 300 μs pulse duration (full width at half-maximum). In our experiments, more than four oscillations a…
A high-speed pulsed laser deposition method with the deposition rate of several tens of microns per 1 h enabled us to obtain isotropic Fe–Pt thick film magnets. Increase in the laser power enabled us to obtain as-deposited films with L10 ordered phase due to the heat radiation from a target, which means that a substra…
Indium zinc oxide (IZO) films were deposited on glass substrates using the rf-magnetron sputtering method and a powder target made up of nanoparticles with a size less than 100 nm. In this study, the optical, structural, and electrical properties of the IZO films deposited using a nanopowder target compared with those…
