The direct pressure measurement shows that the specific volume of hydrogen, which is sorbed by a hybrid sample in the temperature range of 8 - 90 K, is nine times greater than for the original carbon matrix. The results obtained can be used for the creation of cryogenic hydrogen stores, as well as for the design of elements of catalytic systems of hydrogen fuel cells. The new concept was proposed that was implemented for the triple system "naphthalene and 2-bromobenzophenone in a neutral octane matrix". The problem of the kinetics of emission of such a triple system was formulated and analytically solved. The new approach has been proposed and implemented to reliably estimate the corresponding slow phosphorescence attenuation times to analyze the process of emission of "very slow" phosphorescence of naphthalene molecules. Studying of properties of crystals of substituted benzophenones may be suitable for their use in the creation of new medicinal substances and new types of phosphors. It is shown that the hybridization of acoustic and low-lying optical branches is a substantially quantum phenomenon, which manifests itself in the low-temperature thermal properties of both bulk solids and nano-structured systems. Structural studies of condensed thin films of crystalline N2-Kr alloys from 5 K to the temperature of the samples existence in the solid phase have been carried out. The phase diagram of the N2-Kr system at temperatures below the nitrogen phase transition (35.6 K) was determined for the first time. The coexistence region of HCP and FCC phases in the concentration range of 58 - 89 mol. % Kr was determined by the method of full profile analysis of the diffraction pattern intensity distribution. These data are required in aerospace field, to improve the physical performance of nanocomposites that can be used to develop new structural elements.   Product Description popup.authors popup.nrat_date 2020-04-02 Close
