Реферат: Nowadays natural gas hydrates attract special attention as a possible source of fossil fuel. According to various estimates, the reserves of hydrocarbons in hydrates exceed considerably explored reserves of natural gas. Due to the clathrate structure the unit volume of the gas hydrate can contain up to 160-180 volumes of pure gas.
Portable dedvices for cryosurgery and therapy
Автор(ы): Kalmykova Z. V.*Makova M. K.*Mezhov-Deglin L. P.*Lanin A. N.*Petrusenko I. V.*Shafranov V. V.*
Реферат: Cryosurgery is a surgical technique that employs freezing to destroy undesirable tissue. Although the prefix \"cryo\" (from the Greek word \"kruos\" for cold) usually refers to temperatures below 120K, cryosurgery deals with temperatures below the freezing temperature of tissue, i.e. about 273K.

Реферат: A neutral donor dissociation into charged fragments typical of electrolytes is one of the reversible reactions satisfying the law of mass action (LMA) [1]. Its application to weak electrolytes results into the formula (Ostwald law) for an important characteristic of the electrolyte, its ionization degree ? [1, 2].
Pseudo-rotational motion of cyclic molecules and thermal conductivity of tetrahydrofuran
Автор(ы): Konstantinov V. A.*Sagan V. V.*Revyakin V. P.*Karachevtseva A. V.*
Реферат: Pseudo-rotation is a large amplitude motion arising from the interaction of two degenerate, or nearly degenerate out-of-plane ring puckering modes in the presence of a small barrier to planarity of the molecule [1]. Pseudo-rotation in tetrahydrofuran (THF), C4H8O, arises from near cancellation of the angular strain forces due to nontetrahedral bond angles in the skeleton ring and torsional forces due to hydrogen-hydrogen repulsion.
Quantum effects in the kinetics of 3Не, 4Не, Н2 and D2sorption by bundles of single-walled carbon nanotubes

Реферат: The low temperature kinetics of sorption of 3He, 4He, H2, and D2 gases by bundles of single-walled carbon nanotubes (SWNT) and the subsequent desorption of these gases from the SWNT bundles has been investigated. The kinetics of gas desorption was investigated on a powder of SWNT bundles compacted into plates under P=1.1 GPa.
Quantum rotor in solid gases: matrix effects on EPR

Реферат: Our study(a) deals with the methyl radical - the simplest organic radical, which is often observed as a transient intermediate species in chemical reactions. Consequently, it has been widely studied both theoretically and experimentally through decades.
Relaxation processes in a week solution of cryocondensed water, heavy water and ethanol with nitrogen and argon
Автор(ы): Drobyshev A. S.*Aldiyarov A. U.*Katpaeva K.*Korshikov E.*Kurnosov V.*Sokolov D.*Timchenko A.*
Реферат: Earlier studies of stability of ethanol molecules in nitrogen cryomatrix showed that the state of immobilized ethanol molecules in the matrix is not stable [1]. A slight increase of temperature of the matrix, long before its evaporation leads to a change in the vibrational spectra in a two-componentsolid solution of ethanol and nitrogen. This article considers the results of continued research in this direction.
The standardization and certification procedures of cryogenic equipmentin Kazakhstan
Реферат: Creation of the Common Economic Space and functioning within the framework of EurAsEC of industrial enterprises requires forming a common base of normative documents to the Member States. Considering the whole increasing role of the cryogenic technologies in the industrial development of the world\'s leading powers, it is necessary to carry out the appropriate set of activities of normative ensuring this occupation.
Theed study OF Ar - Kr equimolar alloy morphology
Автор(ы): Danchuk V. V.*Mysko N. S.*Solodovnik A. A.*Strzhemechny M. A.*
Реферат: Solid Binary mixtures of cryocrystals are of considerable interest for many reasons [1]. One of them is the possibility of the compare the experimental results with theoretical predictions. According theoretical model of rare - gas binary alloys proposed by Prigogine [2] the solutions should separate in the pure components below about 40 K. This critical temperature depends on the concentration and is a maximum for an equimolar solution.
