Under irradiation, the acceleration of growth of nuclear reactor components made of Zircaloy is clearly correlated to the presence of ⟨c⟩ component dislocation loops. In the early stages, these loops appear to be essentially located close to the intermetallic precipitates. At higher doses, when ⟨c⟩ component dislocati…

Data are given on Zr alloy E635 (Zr-l.2Sn-lNb-0.4Fe), developed in Russia as a fuel rod cladding and other component material for use in cores of VVER and RBMK types. The alloy is much superior to binary alloys with 1.0 and 2.5% Nb and Zircaloys in terms of its resistance to irradiation-induced creep and growth and no…

The effective diffusivities of glucose and its linear analog glucitol were measured by a liquid chromatographic technique at 30 °C within water-filled silica and aluminosilicate catalysts of mean pore size ranging from 7.4 to 116 Å. For glucose, the effective diffusivity decreased from 1.08 × 10 -6 to 1.77 × 10 -9 cm…

Water-soluble polymers carrying a small fraction of hydrophobic groups are able to insert these groups into the hydrophobic interior of lipid bilayers or membranes. Under certain conditions such polymers can interconnect different vesicles or biological cells. With increasing polymer concentration this leads to the fo…

Mechanical activation leads to a variety of defects in MoO 3 . The behavior of paramagnetic defects in unmilled MoO 3 and in MoO 3 mechanically activated in a planetary mill for 600 min was investigated by ESR spectroscopy. MoO 3 milled for 600 min, and unmilled MoO 3 though in a smaller concentration, contain Mo 5+ i…

Vanadium dioxide thin films have been made from vanadium oxoalkoxides. The precursor solution is spin-coated onto a silica substrate and heated under a reducing atmosphere. These VO2 films exhibit well known insulator–metal transition at around 67 °C. Electrical switches have been made from such films that reversibly…

For V-shaped surface grooves in copper, we have obtained the capillary driven flow kinetics for two liquids: unreactive 1-heptanol and eutectic Sn/Pb solder, which is known to react with copper. We show experimentally that the flow of both liquids in these grooves follows the classical Washburn kinetics, i.e., a Poise…
