A high-precision X-ray diffraction study of crystals with the nominal compositions (Na 0.5 Y 0.495 Er 0.005 )WO 4 and (Na 0.5 Gd 0.25 La 0.25 )MoO 4 and the subsequent refinement and analysis of their compositions showed that an increased number of vacancies at the tungsten sites contributes to the cracking of crystal…
The location procedure of HIF is a very difficult task and represents a great challenge for distance protection of transmission lines due to the under-reach and overreach effects. A new contribution for high impedance fault location for short transmission lines is proposed in this paper. The basic idea consists in sol…
The role of magnetic anisotropy and crystallographic texture in determining rf properties of ferrites, and their performance characteristics when integrated within high frequency devices, is explored. Both thin film epitaxial and bulk polycrystalline texture are discussed defining viable paths to realizing crystallogr…
Medium density fiber board (MDF) is an engineered wood product which possesses medium density than normal wood and is widely applicable in interior and exterior applications in industries. Normally in drilling process the materials reduce their performance due to delamination. The objective of this paper is to estimat…
Triglyceride oil of plant seed cannot be used on its own without further modification. The fatty acids must be suitably functionalized in order to add polymerisable functionalities which will help in the curing process. The purpose of these modifications is to reach a higher level of molecular weight and cross-link de…
When the molten fuel with high temperature falls into the cavity water, it will be dispersed into droplets which are covered with vapor films due to the rapid heat transfer with phase transition. This situation cannot be simply described by liquid-liquid or gas-liquid systems. And there are no sufficient experimental…
Locally selective formation of gold nanostructures on a silicon wafer without photolithography, electrolysis, or hydrofluoric acid was reported previously. With our previous method, gold nanostructures grow selectively on the locally amorphized surface on a silicon wafer when the silicon wafer is exposed to a customiz…
The general scheme of conversion of hydrocarbon fuels with new experimental data on the formation of fullerenes and graphenes taking into account the pressure effect is proposed for the fuel-rich flames. It is shown that the formation of fullerenes is important to the corresponding spatial orientation of PAH, possible…
Copper Tin Sulfide (Cu2SnS3), one of the promising absorber layer for thin film solar cell, was successfully deposited on glass substrate maintained at a substrate temperature of 325° C by chemical spray pyrolysis technique (CSP). Variation in copper concentration in the precursor solution affects the structural, opti…
The synthesis of single-crystal silicon (Si) nanowires by a metal-catalyst-free vapor-liquid-solid (VLS) process was studied. Silicon nanowires have been successfully synthesized by simple thermal treatment without any metal catalyst. For cases without metal catalysts, Si nanowires are grown by VLS processes assisted…
The preparation of a steam-based hydrothermally stable transition alumina is reported.
Photodynamic therapy (PDT), an inducer of oxidative stress, is used for treatment of cancer, including brain tumors. To study the mechanisms of photodynamic injury of neurons and glial cells (GC), we used a simple model object — isolated crayfish mechanoreceptor consisting of a single sensory neuron surrounded by a mu…
In order to increase the anti-counterfeiting performance of optically variable devices, the innovative interference security image structures based on metamerism have been developed. In this letter, we show a pair of all-dielectric metameric filters offering a hidden image effect with the color shift at a specific ang…
Silicon wafers (p-type) were etched under continuous flow of HF vapors in a reaction chamber at standard temperature and pressure. Etched surface of the silicon wafer was found emitting red luminescence when exposed to ultra violet (UV) light. XRD and Atomic Force Microscopy of the etched samples were carried out to s…
Abstract A comparative study of Kelvin Probe (KP) surface work function analysis of p-type CuO thin films to its nanowires is presented. Thin films were prepared by RF magnetron sputtering and nanowires were grown by thermal oxidation of grown thin films. The structural characterization was carried out by SEM and micr…

The influence of grain refiner on the microstructure and mechanical properties of pure aluminum was investigated by separate and combined addition trace ScZr elements. The results show that the grain refinement effect of 0.2%Zr added alone is better than that of 0.2%Sc, each of them separate addition can make the stre…
Nanofibrous mats were obtained from electrospinning Nylon-6 solutions with concentrations of 30 and 35 wt% and were tested for filtration of polystyrene particles in suspension. Some experimental results were compared with the simulated ones. In the simulation, the two-dimensional structures were constructed by random…
Two spherical composite adsorbents namely polyacrylonitrilepotassium cobalt hexacyanoferrates (PAN-KCoCF) and polyacrylonitrilepotassium nickel hexacyanoferrates (PAN-KNiCF) were synthesized. The effects of liquid flow rate, bed height and presence of other cations on the adsorption of cesium were investigated by cond…
Conducting magnesium doped (0 to 1.5 wt %) tin oxide thin films prepared by Spray Pyrolysis technique achieved detection of 1000 ppm of LPG. The films deposited at 304 °C exhibit an enhanced response at an operating temperature of 350 °C. The microstructural properties are studied by means of X-ray diffraction. AC con…
