Potential change of electrolytically deposited zinc on a steel substrate in time without a current is studied and at anode polarization in a solution of perchloric acid Influence of density of a polarizing current, way of preliminary preparation of a steel basis of an electrode on size of potential of a zinc covering…
Rhodococcus sp. strain DK17 possesses three megaplasmids (380 kb pDK1, 330 kb pDK2, and 750 kb pDK3). The alkylbenzene-degrading genes (akbABCDEF) are present on pDK2 while the phthalate operons which are duplicated are present on both pDK2 (ophA’B’C’R’) and pDK3 (ophABCR). DK17 with an optimal temperature of 30°C sho…
O carbureto de silício (SiC), um material cerâmico amplamente utilizado nas indústrias de refratários, de fundição e de abrasivos, é produzido industrialmente no forno Acheson através do aquecimento de uma mistura de grãos de carbono (normalmente coque de petróleo) e areia silicosa de alta pureza. Este aquecimento aco…
On example of uniaxial model there was offered the method of forming of non-linear viscous-elastic properties of materials. The offered scheme can be further applied at 3-D modeling of viscous-elastic properties, for instance, asphalt-concrete.
Ces travaux de thèse ont eu pour objectif la mise au point de revêtements anti-corrosion obtenus par voie sol-gel sur alliage de zinc et issus de solutions majoritairement aqueuse. Cette étude a donc porté sur la recherche de performances anti-corrosion demandées par la société Umicore, mais aussi, sur la compréhensio…
Catalytic centers are formed on a substrate of nickel film on a silicon substrate with a sublayer of vanadium, heated in the reactor module nanotech complex NANOFAB NTF-9 in the working atmosphere of ammonia gas, and argon. Were investigated regimes of catalytic centers in various stages of their formation is also car…
To understand the interplay of magnetism and superconductivity in oxypnictides, we have studied simultaneous carrier doping in different layers of CeOFeAs; F in CeO and Co in FeAs. The rf penetration depth shows exponential temperature dependence with gap values ∼1.9 and 1.6 meV for optimal F‐doped and F & Co‐doped sa…
ZnO has proven to be a multifunctional material with important nanotechnological applications. ZnO nanostructures can be grown in various forms such as nanowires, nanorods, nanobelts, nanocombs etc. In this work, ZnO nanostructures are grown in a double quartz tube configuration thermal Chemical Vapor Deposition (CVD)…
The self diffusions and hole volumes of amorphous region of poly(acrylonitrile)-poly(vinyl chloride) fibers were investigated by experiments of stress relaxation. The experiments of stress relaxation were carried out using the tensile tester with the solvent chamber. The flow parameters of filament fibers were obtaine…
В работе изучены структурные изменения в криогенно-деформированной меди в ходе длительной (до 2 лет) выдержки при комнатной температуре. Установлено, что структура, сформировавшаяся в результате больших (e ~ 8.2) криогенных деформаций, является нестабильной и в ней имеет место аномальный рост зерен. Показано, что данн…
Carbon materials are used extensively as supports in heterogeneous catalysis, even if they are relatively inert when compared to the inorganic oxides used commonly. These materials are cheap, have a high specific surface area and can withstand high temperature and high moisture degree. However, carbonaceous materials…
Stress and strain state calculation of the wave gear flexible shell taking into account additional strain loading is given in the article. The differential equations for determination of the loadings and motions in the flexible shell and ring collar of the wave gear are received. The solution of the equations is shown…
Megvizsgáltuk kétfalú szén nanocsövekben a falak közötti kölcsönhatást és meghatároztuk a következtében fellépő töltésátvitelt; hasonlóképpen megvizsgáltuk ferrocénnel töltött nanocsövekben a ferrocén és a nanocső kölcsönhatását. A szén nanocsövek helikális szimmetriáját kihasználva kidolgoztunk egy egyszerű eljárást…
We have conducted X-ray fluorescence and X-ray diffraction analysis of a series of cubic zirconia crystals stabilized with yttrium and gadolinium and doped with neodymium. The structure of the crystals under study has been refined, with the uncertainty factor being less than 3% for all the crystals examined. The depen…

Tomando como base la necesidad que tienen las micro y pymes metalmecanicas de ser cada dia mas competitivasy productivas se presenta un enfoque y revision de los factores mas relevantes que permiten generar ambientes concurrentes en las empresas y como estos afectan positivamente el desarrollo de construcciones soldad…
New classes of continuously metallic and 'dielectric-loaded' relief metamaterials (raised or indented sub-wavelength patterns on continuous, non-perforated metal surfaces) enable manipulation of reflected light intensity and phase in the visible-infrared range. Perfect absorption, colour control, field enhancement and…
The mixed-valent nature of nonstoichiometric ceria (CeO2-δ) gives rise to a wide range of intriguing properties, such as mixed ionic and electronic conduction and oxygen storage. Surface and transport behavior in rare-earth (samaria) doped and undoped ceria were investigated, with particular emphasis on applications i…
The concept of element and its applications to improving the human condition and understanding of the structure of matter (the radiation being a manifestation of the matter) plunging into the origin of civilizations. The efforts made along of decades have crystallized in the laws of Mendeleev and Moseley, the analysis…
