Various oxide films have been grown on AZ31 magnesium alloy by microarc oxidation in alkaline phosphate solution with addition of different compounds (Na2SiO3, NaAlO2). Because of the anodic oxide porosity, arising from the sparking treatment, organo-functional silane coatings have been applied to seal pores and crack…
Investigation of the I-V characteristics of the DSSC based on interconnected with cobalt-doped SnO2 nanoparticles covered with a nano-scale thin layer which was absorbed by natural dyes are described. The presence of co-doped SnO2 has been confirmed by its characteristic XRD pattern and the shape of the particle is co…
For the diffusion-kinetic model of combustion of a porous carbon particle in air, the structure of the reaction zone of carbon with reactive gases inside the porous particle is studied. It is shown that, for the given kinetics of reaction of carbon with oxygen, the dependence of combustion rate of the porous particle…
The absorbing performance have been tested and analyzed by taking cement as matrix, blending material silica fume and culver zed fuel ash for absorbing agent trial Sample, in the 8 ~ 18 GHz frequency band, the results indicate that silica fume and culver zed fly ash and composite cement which made of Absorbing materia…
ZnO–ZnS porous films were formed by low-temperature sulfidation of three-dimensional (3D) ZnO porous templates. The conversion of ZnO to ZnS initialized at the ZnO surface, accompanied by volume expansion. ZnS grains were preferentially formed at the surface of ZnO blocking the pseudotriangular pores. During sulfidati…
3-{[(2-Hydroxyphenyl)methylidene]amino}propane-1,2-diol, its 5-chloro-,5-bromo-, 5-nitro-, 3-methoxy derivatives, and 3-{[(2-hydroxynaphthyl-1)methylidene]amino}propane-1,2-diol react with hydrates of copper(II) chloride, bromide and nitrate in ethanol to form coordination compounds Cu(L)X· n H 2 O. Template condensat…
The Np(IV) complex [Np(DMSO) 7 (NO 3 )](ClO 4 ) 3 was synthesized and studied by single crystal X-ray structural analysis. The crystal structure contains three crystallographically independent formula units. The complex cations [Np(DMSO) 7 (NO 3 )] 3+ contain bidentate chelate nitrate ions and DMSO molecules coordinat…
This paper presents a method for calculating iron losses in three-phase induction motors under the inverter supply through the field-circuit coupled time-stepping finite element method (FEM). Iron losses are calculated by using the three-term iron losses separated model and modifying the loss coefficients obtained by…
In this study, chelerythrine nanoparticles composed of magnetic multiwalled carbon nanotubes (Fe3O4/MWNTs-CHE) were prepared by adsorption method with CHE as the model drug and Fe3O4/MWNTs nanocomposites as the drug carrier. Optimized nanoparticles were characterized by scanning electron microscopy (SEM), Zeta potenti…
Crystallographic structures of the three NaSbR(PO 4 ) 3 (R = Cr, Fe, In) phases were determined at room temperature from X-ray powder diffraction (XRD) data using the Rietveld analysis. The three compounds belong to the Nasicon structural family. The presence of the (303) reflection in all XRD spectra of NaSbR(PO 4 )…
The structure and tribological behavior of the AK12M2MgN alloy reinforced by nanostructured fillers based on BN and SiO 2 micropowders are studied. It is shown that the modification of the micropowders by reactive elements is accompanied by the synthesis of nanosized ceramic compounds on their particles. This structur…
The main objective of this study is to estimate nuclear data uncertainties on the effective multiplication factor (Keff) related to elastic, inelastic, capture and fission cross sections and the correlations between them. Different rapid and thermal cases of the different IHECSBE benchmarks have been studied by using…
To study the malfunction cause and wear mechanism of aluminum brass in gun recoil brake, based on microscopic analysis technology, scrapped throttling ring from the repair facility as research objects, the throttling ring wear mechanism is analyzed systematically from the microscopic point integrated use of metallurgi…
Two fluorescent anion sensors bearing phenol, carbazole-NH and -NO 2 group were designed and synthesized. They both exhibited highly binding ability for H 2 PO 4 -among the anions tested. In the presence of H 2 PO 4 -, the fluorescence of the sensors underwent a dramatic enhancement, while the presence of other anions…
The influence of doping on the photoluminescence of a system consisting of silicon nanocrystals in silicon dioxide matrix is analyzed. The nanocrystals were grown by annealing of a silicon dioxide deposited with an excess of silicon and then passivated in a Forming Gas atmosphere. The doping of the nanocrystals with b…
Tricardanolic phosphite was synthesized in 65% yield. This cardanol-derived small molecular compound was successfully transformed into UV-cured resin via thiol-ene click reaction, by using 4,4-di (mercaptomethyl) benzophenone as both a photoinitiator and a crosslinker. The fully bio-based P-and S-containing resin is e…
The X-ray micro-diffraction laboratory technique was applied to study the quantitative changes of austenite content in TRIP steels after deformation and to reveal the phase composition of precipitates in an inner part of a hearth of a blast furnace. The usefulness of this technique was shown by calculating the austeni…
