Forbidden gaps of one-dimensional compound photonic crystals consisting of cholesteric liquid crystals sandwiched by periodic isotropic layers are investigated. The common forbidden gaps appear for both incident left and right polarization light which is different from the cholesteric liquid crystals. The forbidden ga…
Cette thèse présente les résultats d'une étude expérimentale sur la solubilité de l'or dans des vapeurs contenant du souffre à l'état réduit à haute pression et température, ainsi que les propriétés PVTx de mélanges gazeux de H2O-H2S. La solubilité de l'or a été mesurée dans du H2S gazeux pur et dans des mélanges gaze…
Deep cold rolling (DCR) and low plasticity burnishing (LPB) process are cold working processes, which easily produce a smooth and work-hardened surface by plastic deformation of surface irregularities. The present work focuses on the surface hardness aspects of AISI 4140 work material, using fractional factorial desig…
The paper presents a theory of thermodynamics and kinetics of short-range ordering in Fe-Ni-C alloys based on the general approach developed by M.A. Shtremel. Equilibrium order parameters and kinetics of their establishing during isothermal holding are calculated for several alloys. Effect of order changes on free ene…

Analysis of various types of production emissions technology, on the basis of which the emission characteristics of matrix, basic equipment of machine-building enterprises.
In article possibilities of system NX for construction of the difficult curves displaying a trajectory of the tool at mechanical electroplating to processing of spherical surfaces are considered. The problems arising at designing of adaptations for mechanical electroplating of processing of spherical surfaces are show…
The nano-perovskites La0.7Sr0.3Mn1xZnxO3 (x = 0, 0.2, 0.3 and 0.4) synthesised by citrate sol-gel method were studied by using Selected Area Electron Diffraction (SAED) and High-Resolution Transmission Electron Microscope (HRTEM) in the bright-field and dark-field configurations. The obtained results show that the gr…
BaZrO3 is a perovskite oxide that is a good candidate for an intermediate\ntemperature proton conductor in SOFC, because it is chemically stable\nand has high bulk proton conductivity. However, the total conductivity of\nthe material is low due to high proton resistance at the grain boundaries.\nTheories suggest that…
In this study, new method of determination of stress-strain curves using indentation and scratch-test was described. The main idea of the method was comparison indentation and scratch-test results receiving by simulation and experiment. Nanoindentation and scratch-test with the Berkovich indenter was conducted on a co…
En este trabajo se han llevado a cabo la preparacion y caracterizacion de nuevos compuestos a base de morteros de cemento reforzados con fibras celulosicas nanofibriladas. El efecto del grado de fibrilacion de las fibras sobre las propiedades mecanicas de los composites resultantes se presenta y analiza en base al tam…
The article contains of research on development of automated calculation of coefficient of damage to fibers and yarns in implementation process warping. During performance, experimental studies of damage to cotton yarn linear density 29 tex during warping process. The calculation of damage to yarn on basis of theory o…
Processes of shock interaction of two types of compound strikers with a weight of 300 g and steel armor plates with a thickness of 50 mm were investigated by the computer modeling method. The impact speed is 1600 m/s. In the first version, the striker was represented as a steel core in a textolite pallet. In the secon…

Pada penelitian ini telah dilakukan sintesis busa poliuretan menggunakan asam oleat, monomer diisosianat berupa TDI (toluena-2…
Amorphous carbon nanotools for cell surgery J.D. Beard, D.J. Burbridge, O. Dudko, A.V. Moskalenko and S.N. Gordeev, Department of Physics, University of Bath Bath BA2 7AY, UK s.gordeev@bath.ac.uk Using a method of electron-beam induced deposition (EBID) of amorphous carbon, we have been able to fabricate free-standing…
The design model of the GTE disk has been developed taking into account centrifugal forces, distributed aerodynamic loads and nonlinear contact conditions. Stress concentration zones near the disk and blade junction are investigated numerically taking into account the impact of different loading factors and contact co…
The effect of anomalous wear of the tempered steel counterbody during testing of coatings obtained by the electric spark plating (ESP) with alloy AlSn (20 wt% Sn) was observed. It is proposed that the reason for effect origin is the SnO 2 nanowires inclusion in the coating composition during ESP with electrode-tool fo…
