The history of the discovery of nanodiamond synthesis, the investigation of nanodiamond properties, and the application and organization of their production in the second half of the 20th century is expounded. It is noted that this history is unique, since nanodiamond synthesis was discovered in the USSR three times over 19 years: first by K.V. Volkov, V.V. Danilenko, and V.I. Elin at the VNIITF (Snezhinsk) in 1963 and then, in 1982, by A.M. Staver and A.I. Lyamkin at the Institute of Hydrodynamics, Siberian Division, Academy of Sciences of the USSR (Novosibirsk), and by G.I. Savvakin at the Institute of Problems of Materials Science, Academy of Sciences of the UkSSR (Kiev). All of these researchers discovered nanodiamond synthesis accidentally while studying diamond synthesis by shock compression of nondiamond carbon modifications in blast chambers. The priority of work by Russian scientists in this field is demonstrated. 相似文献

The morphological and catalytic properties of samples of nanomeric zirconium dioxide, stabilized with yttrium oxide, manufactured
via the effect of a UHF field during the process of drying precipitated zirconium hydroxide and calcination at temperatures
from 300 to 1000 °C, were studied. It was shown that the highest activity in the oxidation of CO occurred with 40 nm particles
of zirconium dioxide prepared at 1000 °C.

Coupling of N,N-bis(silyloxy)enamines with tertiary amines and nitrogen-containing heterocycles affording the corresponding functionalized ammonium or iminium salts was studied. The area of its application was determined, and optimal procedures for the synthesis of the target products were proposed. The mechanism including the formation of conjugated nitroso alkene or a silylnitrosonium cation as key intermediates is discussed.__________Published in Russian in Izvestiya Akademii Nauk.

The concentration dependences of heat capacities of aqueous solutions of several amino acid and peptide derivatives of fullerene
were measured by scanning differential calorimetry at 298 K. The heat capacities for the arginine, alanylalanine, and glycylvaline
derivatives dissolved in water depend slightly on concentration. The concentration dependences of the heat capacities of aqueous
solutions of the serine and alanine derivatives display extrema. The calculated contributions of hydration to the heat capacities
of the dissolved fullerene derivatives have both positive and negative signs.

An X-ray diffraction technique for the study of imperfect crystals of natural graphite and its fluorinated products is proposed. The diffraction patterns measured are free from the preferred orientation effect and provide the simulation based on a 1D disordered crystal. 相似文献

The (C,F)-construction from a previous paper of the first authoris applied to produce a number of funny rank one infinite measurepreserving actions of discrete countable Abelian groups G withunusual multiple recurrence properties. In particular,the following are constructed for each p N{}:
- a p-recurrent actionT=(Tg)gG such that (if p) no one transformationTg is (p+1)-recurrentfor every element g of infinite order;
- an action T=(Tg)gGsuch that for every finite sequence g1,...,grGwithout torsionthe transformation Tg1x...x Tgr is ergodic,p-recurrent but(if p) not (p+1)-recurrent;
- a p-polynomially recurrent (C,F)-transformationwhich (if p)is not (p+1)-recurrent.

The advantages and disadvantages of the method of automatic analysis of electron backscattering diffraction (EBSD) patterns for studying spatial orientation distributions are considered as compared to transmission electron microscopy (TEM). A misorientation spectrum in a test alloy (Kh20N80 alloy) having a high content of annealing twins is experimentally studied using both TEM and EBSD, and the results obtained are compared. 相似文献

LetG be a countable direct sum of finite groups. We construct an uncountable family of pairwise disjoint mixing (of any order)
rank-one strictly ergodic free actions ofG on a Cantor set. All of them possess the property of minimal self-joinings (of any order). Moreover, an example of rigid
weakly mixing rank-one strictly ergodic freeG-action is given.
