An in-house drawn chalcogenide fiber sustained 12.2 MW/cm2 CW irradiation on the facet without damage, limited by available laser power. After depositing single-layer, anti-reflection coatings on the fiber facets, 90.6% transmission was achieved with 10.2 W output.
A “turn-off” fluorometric detection method for sodium hexametaphosphate (SHMP) with a terbium( iii ) complex of 4,4′,4′′-((1,3,5-triazine-2,4,6-triyl)-tris(azanediyl))-tribenzoic acid (H 3 TATAB) is developed.
System of test tasks is presented with the fast reactor BN-1200 with nitride fuel as prototype. The system of test tasks includes three test based on different geometric models. Model of fuel element in homogeneous and in heterogeneous form, model of fuel assembly in height-heterogeneous and full heterogeneous form, a…
In this study, the thermal stability of nanostructured Al-Mg alloy powders was investigated. Two alloy compositions, Al-5Mg-0.1Er and Al-5Mg-0.5Er (wt.%), were cryogenically milled for 30 h to produce nanostructured powders. The microstructure of the milled powders with increasing temperature was investigated by diffe…
The historical stages and modern achievements in the field of increasingly growing use of electricity in aircrafts both in Russia and abroad are analyzed. The analysis results are used as a basis for presenting the key technologies using which the concept of constructing a fully electrical aircraft can be embodied. Th…
The second law analysis for free convection heat transfer along a cone embedded in a nanofluid saturated non-Darcy porous medium with the effects of viscous dissipation and Newtonian heating is studied in the current paper. The model used for the nanofluid refers to a solid–liquid mixture with a continuous phase which…
A new approach for the modification of polylactic acid (PLA) materials using atmospheric pressure plasma (APP) is described. PLA films plasma exposure time was 20, 60, 120 s. The surface morphology and wettability of the obtained PLA films were investigated by atomic force microscopy (AFM) and the sitting drop method.…
The behaviours of the Zinc coating would be subjected to the complex zinc anion, and also the additives, current densities and compositions of electroplating bath. In this study, the complex agents (anise aldehyde and Lugalvan P) were added into the electroplating bath to improve the anti-corrosion ability and inhibit…
We examine the impact of a single spherical drop on a flat, dry, cold, and smooth surface. A large number of published experimental observations were collected and analyzed with the aid of the COMSOL Multiphysics software to yield a unified correlation that relates both the maximal spreading drop diameter and the corr…
Biocomposites based on bioinert metals or alloys and bioactive calcium phosphate coatings are a promising tendency of the new-generation implants development. In recent years, the approach of regenerative medicine based on the use of biodegradable biomaterials has been priority direction. Such materials are capable of…
Colored hot dip galvanization of various steel samples was realized in an industrial bath containing 738 kg of a Zn-Mn liquid alloy at 450?C. Zinc was alloyed in three steps to reach 0.1, 0.15 and 0.2 w% of Mn in liquid zinc, and galvanization of 9 different steel samples was performed in all three baths. The obtained…
Online impulse frequency response analysis (IFRA) is an advanced method for detecting winding faults in transformers. In this method, square wave impulse is commonly used as the excitation signal. In theory, the frequency response curve of a transformer is not related to the excitation signal. However, it is discovere…
Solid polymer electrolytes (SPEs) composed of a blend of Poly(ethyl methacrylate) (PEMA) and Epoxidized Natural Rubber-50 (ENR-50) and Lithium triflate (LiCF3SO3) were prepared by solution casting technique. The conductivity was measured by using electrical impedance spectroscopy (EIS). Measurement of conductivity was…
Coupling of titania with narrow band gap materials has been a promising strategy in preparing visible light responsive photocatalyst. In this work, self-organized copper decorated TiO2 nanotube (Cu/TNT) was prepared via electrodeposition of Cu onto highly ordered titania nanotube arrays (TNT). The catalysts were chara…
A new triazolium-based receptor for fluorescent sensing of inorganic fluoride anions in semi-aqueous solution and the solid state was reported.
Several k∞ experiments were performed on the KBR critical facility at the Institute of Physics and Power Engineering (IPPE), Obninsk, Russia during the 1970s and 80s for study of neutron absorption properties of Cr, Mn, Fe, Ni, Zr, and Mo. Calculations of these benchmarks with almost any modern evaluated nuclear data…
Activity of La0.8Sr0.2FeO3 (LSF) to the fuel electrode reaction in Solid Oxide Reversible Cells (SORCs) was investigated by using La0.9Sr0.1Ga0.8Mg0.2O3 (LSGM) and Ba0.6La0.4CoO3 (BLC) as electrolyte and air electrode, respectively. In electrolysis mode (SOEC), LSF electrode exhibited small overpotential under the atm…
