Abstract The work presents the results of the investigations of the effect of inhibitors coated on the internal walls of a ceramic mould on the quality of the obtained casts made of the AM60 alloy containing additions of chromium and vanadium. In order to reduce the reactivity of magnesium alloy cast by the technology…
The enhancement effects for solar cell are examined on the plasmonic properties of Ag nanowires (AgNWs) arrays, which fabricated by dielectrophoresis techniques. AgNWs in 100 nm diameters with aspect ratio (AR) of 100 were assembled into an array between the micrometer spaced electrodes by applying an AC electric fiel…
Corrosion inhibitors are chemicals that are used in many industries to control corro-sion. As they are injected into process streams they have to be continually replen-ished in order to maintain protection. Many chemicals used are environmentally un-friendly highly toxic compounds including chromates and arsenic compo…
A Metal-Insulator-Metal (MIM) Plasmonic Focusing Cavity is simulated. The structure includes a large upper metallic grating to couple incident light into the cavity and a small lower metallic grating to couple the light into the Avalanche Photodiode (APD) below the MIM cavity. Our results provide a possibility to redu…
A hybrid distillation-vapour permeation (D-VP) system was selected to get Isopropanol (IPA) with high purity. In this study, a technical and economic analysis was performed comparing the hybrid D-VP systems with polymeric (PVA/PVDF) and ceramic (NaA type zeolite) membranes. Response surface methodology (RSM) was used…
The structure and magnetic properties of ferromagnetic Tb1-xGdxFe2system have been studied through the morphotropic phase boundary (MPB), a phase boundary between two ferroic phases of different crystal symmetry. Morphotropic phase boundary (MPB) has been studied extensively for its extraordinary enhancement effect in…
Thermal properties, microstructure and magnetic properties of Fe79Zr9B12, Fe76Zr9B15, Fe39.5Co39.5Zr9B12 and Fe38Co38Zr9B15 alloys were investigated by dierential thermal analysis, X-ray diraction and vibrating sample magnetometer. High Co addition has a signicant impact on the properties of alloys. High Co addition i…
Reactive molecular dynamics simulations are used to simulate the chemical mechanical polishing process of silicon surface. The simulation process is carried out to investigate the interaction between SiO2 particle and Si surface in pure water. Both chemical and mechanical effects under different pressure between the s…
This work presents an electrochemical investigation of chemical reaction kinetics in CMP of Ti in a peroxide-based alkaline medium. Linear polarization scanning (LP) is combined with electrochemical impedance spectroscopy (EIS) to probe the chemical roles of H2O2 and OH− in CMP. The equivalent circuit is obtained from…
Gallium Nitride is one of most important compound semiconductor materials in recent years. It is of particular interest due to its wider band gap energy (3.4eV), high electron saturation velocity (2.7×107cm/s), high breakdown field (3.3MV/cm) and chemical inert properties. A lot of researches have been focused on its…
Due to stricter environmental regulations for minimizing NO x emissions, the urge to apply efficient catalysts is a worldwide concern.Among the technologies for controlling NO x -emissions, the selective catalytic reduction of NO x (SCR-DeNO x ) is the main industrial application.Vanadia supported on mesoporous titani…
Beginning with the 20th century metal structures are widely used in the construction branch in Russia. The reason for it was in the development of calculation methods of structures. Beginning with 1930 and till now a substantial number of the industrial buildings (about 90 %) of production plants have been built of me…
Abstract Titanylphthalocyanine takes various crystal polymorphism. The titanylphthalocyanine with Y-form shows excellent optical and photoelectric conversion. However, preparing the Y-form titanylphthalocyanine nanocrystals smaller than 200 nm is difficult. Here, we prepared Y-form titanylphthalocyanine nanocrystals s…
Omul a fost preocupat de-a lungul istoriei evoluţiei sale de folosirea materialelor din jur pentru a-si usura si imbunataţi activitaţile. De la confecţionarea armelor de vânatoare, uneltelor pentru agricultura si la realizarea de masini complexe, omul a preluat si prelucrat materialele din jur. Preocuparea actuala est…

The article presents obtained measurement results of transformer mechanical vibration for two cases of its operation: with twisted and loosened…
We investigated the effect of Xe dilution of silane on structural, optical and electrical properties of nanocrystalline Si films deposited by HW-CVD. With increase in Xe dilution of silane nanocrystalline-to-amorphous transition or amorphization has been observed in nanocrystalline Si films. The amorphization has been…
Spectral and directional control of thermal emission based on excitation of confined electromagnetic resonant modes paves a viable way for the design and construction of microscale thermal emitters/absorbers. In this paper, we present numerical simulation results of the thermal radiative properties of a silicon carbid…
We investigate several issues related to the electronic states in the ligand orbital of a given transition-metal salt as, for example, a K2CuCl42H2O-type compound. In fact, to get our calculation, we start from an expression for the electronic density of states in a compound of the above type. In addition, various asp…
