Highly ordered mesoporous carbon (CMK-3) was fabricated for the adsorption of cobalt from aqueous solutions. With the high surface area of1112.7m2/g and pore size of 17.2 nm, its abundant mesopores were benefit for providing channels for liquid propagate. In order to improve the adsorption properties,CMK-3 was modifie…
Sn2Sb2S5thin films were elaborated by vacuum thermal evaporation and annealed at different temperatures during lh in air atmosphere. XRD data analysis shows that annealed films crystallize in the orthorhombic structure according to a preferential direction (602). The optical properties of thin films were determined fr…
The power quality (PQ) management is the key issue in electrical power system and industries are facing this issues around the world. The hybrid filter configuration with PI Controller is more efficient scheme for the improvement of power quality in power system. The main purpose of this work is to reduce the effects…
Present study focuses on investigating the hot dip galvanizing effect on the mechanical properties of high strength steel. The effect of chemical pre-treatment (hydrogen diffusion) and the effect of hot dip galvanizing temperature on mechanical properties was studied with high strength steel S650MC. Additional tests w…
WO3 has been widely applied in many fields such as electrochromic window, photocatalyst, and gas-senor. In this paper, WO3/S core/shell nanoparticles were synthesized in high density and large scale on silicon substrates via simple thermal evaporation of WO3 and S powders at 950 °C in a tube furnace. The morphology, c…
In this work, we have demonstrated that two-wavelength thermoreflectance technique can be used to characterize the local thickness and temperature of heated cantilevers at steady-state operation. By taking the ratio of reflectances for two lasers with different wavelengths, the geometrical factor causing the mismatch…
In this paper, the analysis and design of the high frequency corona generator with LCC resonant topology applied in film treatment is proposed. The designed converter works with a specified output voltage, which makes the film treatment efficient and stable. By making the converter operate in a critical mode, the anal…
The formation of zones with anomalously high values of the basic flow characteristics in decompression waves in a heavy cavitating magma with an intense increase in the density of cavitation nuclei is numerically studied within the framework of a mathematical model of multiphase media with a system of kinetic equation…
Highly epitaxial LaBaCo2O5+δthin films are successfully fabricated and annealed in different ambient conditions. The LaBaCo2O5+δthin films under O2and N2annealing atmosphere arec-axis oriented with the interface relationship of [100]LBCO//[10LAOand (001)LBCO//(001)LAO. Annealing the film in N2ambient significantly inc…

In this study, the yttrium oxide (Y2O3) thin films were deposited on the sapphire substrates by RF reactive magnetron sputtering with varying sput…
Neste trabalho é apresentado um modelo descritivo para explanar a geração de tensões térmicas em soldagem, denominado de Modelo de 5 Barras. Tomando como base o Modelo de 3 Barras amplamente utilizado com a mesma finalidade, se reivindica que o modelo proposto seja capaz de explicar a geração das tensões também na ZAC…
Abstract Goal of the present research was to study immittance properties of BiNbO4 ceramics fabricated by the solid state reaction route followed by pressureless sintering. Four sets of samples were examined, namely the one fabricated from the stoichiometric mixture of oxides, viz. Bi2O3 and Nb2O5 as well as the ones…
The crystal structure of two modifications of [PdEn(NO 2 ) 2 ] is determined by single crystal X-ray diffraction. The geometric characteristics of the complexes and the motifs of their mutual arrangement in the structures are compared. The thermal properties in different gaseous atmospheres are studied.
By the example of ion-molecular reactions in fluoride systems, including alkali metals, we show the influence of the effusion chamber material and of the inserted addition agents on formation of the ion emitting surface. In the mass-spectrometric experiment, the possibility of polarization of this surface upon ion cur…
The processes of capillary condensation and capillary evaporation in a wedge-shaped crack are considered. Capillary evaporation is a comparatively new phenomenon that is opposite to capillary condensation and occurs upon the cleavage of a solid in a nonwetting liquid. For both cases, the positions of a meniscus inside…
The object of investigation is photoresponse spectra taken from the cleaved end face of heterojunctions formed by GaSe and InSe anisotropic crystals. Spectra taken from the as-prepared and chemically processed faces of the heterojunctions are compared. A modified method of growing GaSe crystals with a virgin end face…
Abstract Polycrystalline aluminium Al99.5 was deformed through the combination of equal-channel angular pressing (ECAP) by B route (4, 8 and 16 passes) and then by the hydrostatic extrusion (HE) using the cumulative way of deformation, just to the achieving the final wire diameter d = 3 mm. The microstructure of sampl…
Nanocrystalline Cu film with a mirror surface finishing is prepared by the electric brush-plating technique. The as-prepared Cu film exhibits a superhydrophilic behavior with an apparent water contact angle smaller than 10°. A subsequent increase in the water contact angle and a final wetting transition from inherent…
