N. A. Antropov E. Yu. Boyarko E. K. Gorbunov K. V. Grigorjev Yu. Yu. Kryuchkov O. G. Chernikov I. P. Chernov 《Bulletin of the Russian Academy of Sciences: Physics》2009,73(11):1496-1498
The problem of homogeneous irradiation of Si ingots of large diameter (i.e., comparable with the thermal neutron diffusion
length in silicon—20 cm) by thermal neutrons is considered. The effect of neutron absorption on the irradiation homogeneity
is discussed. It is established for some usual cases of neutron doping that the neutron distribution in the irradiation zone
affects the irradiation homogeneity. The results obtained can be useful for choosing and designing the irradiation zone for
neutron doping of silicon. 相似文献

Thermodynamic characteristics of stepwise dissociation of glycyl-glycyl-glycine in aqueous solutions
A. I. Lytkin V. V. Chernikov O. N. Krutova G. G. Gorboletova I. A. Skvortsov A. S. Korchagina 《Russian Journal of Inorganic Chemistry》2017,62(2):240-243
The heats of interaction between glycyl-glycyl-glycine and solutions of nitric acid and potassium hydroxide are determined by calorimetry at 298.15 K and ionic strengths of 0.25, 0.50, and 0.75 in the presence of KNO3. The standard thermodynamic characteristics (Δr H°, Δr G°, and Δr S°) of acid–base interaction in aqueous solutions of the peptide are calculated. The effect of background electrolyte concentration on the enthalpy of dissociation of glycyl-glycyl-glycine is discussed. 相似文献

Enthalpies of complex formation for glycine (HL±) with Ce3+ and Er3+ ions at 298.15 K and the value of the ionic strength of 0.5 (KNO3) are determined by calorimetric means using two independent procedures. Thermodynamic characteristics of the reactions of formation for complexes of glycine with Ce3+ and Er3+ ions at various [metal]: [ligand] molar ratios are calculated. 相似文献

The heat effects of the reaction of a solution of D,L-tryptophan with solutions of KOH and HNO3 were measured by calorimetry at temperatures of 288.15, 298.15, and 308.15 K and ionic strength values of 0.25, 0.5, and
0.75 (KNO3). The effect of the temperature and concentration of the background electrolyte on the heats of dissociation of amino acid
was considered. The standard heat effects of ionization of D,L-tryptophan were determined by extrapolation to zero ionic strength.
The standard thermodynamical characteristics of the stepwise dissociation of D,L-tryptophan were calculated. 相似文献

A microwave discharge initiated by a surface wave on a dielectric body placed in a supersonic air flow is studied. The discharge
is shown to represent a thin plasma layer that uniformly covers the antenna surface. In experiments, the discharge propagation
velocity may be as high as 100 km/s, which is several orders of magnitude higher than the velocity of sound in air. The peak
pulse power necessary to excite the discharge in a wide range of air pressures (from 10−3 to 103 Torr) is no higher than 100 kW. It is shown that the gas temperature may rise to 1000–2000 K, rapidly increasing (with a
rate of ≈50 K/μs) at the early stage of discharge evolution. The discharge of this type may find applications in super-and
hypersonic plasma aerodynamics (such as control of the flow near the surface of a body moving in a dense atmosphere, reduction
of surface friction, optimization of ignition and combustion conditions for supersonic flows of gaseous fuel, etc.). It may
also be used to advantage in development of new-generation plasma sources for micro-and nanoelectronics purposes (plasma treatment
of surfaces, etching, and film deposition). 相似文献
