Thin SnS films are of interest for optoelectronics. The influence of the preparation modes on the microstructure and electrical properties of thin SnS films obtained by the hot-wall method on substrates made of pure glass and glass with a molybdenum sublayer has been investigated. It has been established that the form…
Solid state electrolytes fabricated with chalcogenide glass (ChG) are considered viable candidates for the next generation of non-volatile memory technologies. These glasses, which are composed of group IV and/or group V elements with those of group VI chalcogens (S, Se, and Te), are excellent metal ion conductors. Be…
The results of measurements of the DD-reaction yields from the Ti/TiO2:Dx heterostructure in the energy range of 10–25 keV are presented. Neutron and proton fluxes were measured using a neutron detector based on He-3 counters and a CR-39 plastic track detector. A comparison with calculations showed the existence of si…
Many adaptive routing protocols have been developed for Networks -on-Chip to improve the network performance by traffic reduction. In this paper, we present an adaptive routing algorithm based upon the Q-routing, which distributes traffic by a learning method in the entire network. The learning method utilizes local a…
Gold nanorods, as an emerging noble metal nanomaterial with unique properties, have become the new exciting focus of theoretical and experimental studies in the past few years. The structure and function of gold nanorods, especially their biocompatibility, optical property, and photothermal effects, have been attracti…

Aqueous solution synthesis of ZnO nanorods on p-GaN(0001) is a low-temperature (< 100 °C) and cost-efficient growth technique of high quality emitters for LED applications. We present morphological, optical and structural properties of zinc oxide nanorod arrays grown by a hydrothermal seed layer-free and rapid synthes…
Traps and trap-related effects in recessed-gate normally-off AlGaN/GaN-based MOSHEMT with SiO2gate dielectric were characterized. Hysteresis in ID-VGwas observed at elevated temperature (∼120oC) due to the traps. To understand the traps, current transient in drain was investigated at given gate and drain pulses with d…
Cement paste with addition of a small amount of (0.9wt%) nano-TiO2 were prepared. Flexural strength and compressive strength testing results showed that by adding a small amount of nano TiO2 with good dispersion, the 28-day flexural strength and compressive strength of cement paste modified by nano-TiO2 was increased…
Diagnosis of electrical equipment, particularly distribution and power transformers has been quite important for quite a long time. Frequency Response Analysis (FRA) has been introduced years ago and has been employed as an off-line diagnosis test since last decade to investigate transformer mechanical integrity. As s…
As the basic of a deeper investigation on the turbulent transport, the fluctuation property in the boundary of the newly-reconstructed Joint Texas Experimental Tokamak (J-TEXT) is studied experimentally using the reciprocating Langmuir four-tip probe, which has been built and operated as the primary diagnostic tool in…
In this second and concluding part of a detailed palynological study of subsurface Mississippian strata(Oriximina and Faro formations) of the Amazonas Basin, the systematic-descriptive account of the miospores iscompleted, specifically dealing with the morphologically more complex forms, totalling 61 species. Thesecom…
A novel procedure for biopolymer surface nanostructuring with defined surface roughness and pattern dimension is presented. The surface properties of sputtered platinum layers on the biocompatible polymer poly(l-lactic acid) (PLLA) are presented. The influence of thermal treatment on surface morphology and electrical…
Granulated blast-furnace slag (GBFS) is a by-product of the metallurgical industry and consists mainly of lime and calcium–magnesium aluminosilicates that defined as the glassy granular material formed by rapid cooling of molten slag with excess water resulting in an amorphous structure. Alkali-activated slag (AAS) bi…
For two PTMSP samples synthesized on various catalytic systems (TaCl 5 /TIBA and NbCl 5 ) and having different chain configurations (the ratio of cis / trans units is equal to 50/50 or 63/37 for PTMSP/Ta and PTMSP/Nb, respectively), sorption and organic solvent nanofiltration (OSN) behavior is studied. Equilibrium sor…
Abstract Titania is one kind of important materials, which has been extensively investigated because of its unique electronic and optical properties. Research efforts have largely focused on the optimization of the dye, but recently the titania nanostructures electrode itself has attracted more attention. It has been…
A nanogranular system composed of CoFe2O4-Cr2O3 core-shell nanoparticles (embedded in SiO2 matrix) having average particle size of 35 ± 5 nm was prepared by chemical synthesis. Structural characterizations by x-ray diffraction, Transmission Electron Microscope (TEM) show highly crystalline phase of these nanocomposite…
The measurement of acoustic and electrical signals for the partial discharge (PD) activity due to the presence of metallic particles within transformer oil are utilized for the characterization of the incipient hazards. The utilization of phase resolved, in addition, to time resolved partial discharge signals is under…
In this paper, an analytical model is established to describe the deposition kinetics and the deposition chamber characteristics that determine the deposition rates of pure boron (PureB-) layers grown by chemical-vapor deposition (CVD) from diborane (B2H6) as gas source on a non-rotating silicon wafer. The model takes…
In this paper, a simplified control algorithm of a three-phase Series Active Power Filter (SAPF) as Power Quality Conditioner is presented. SAPF compensates supply voltage distortions/unbalance, supply voltage harmonics in a view as such they does not reach at the load end with very low THD in load voltage. The series…
