Аннотация: The phase composition of iron films prepared by pulsed-plasma deposition in a controlled nitrogen atmosphere is investigated by Mossbauer spectroscopy. The observed changes in the phase composition are dictated by the nanocrystalline structure of the samples and the dynamics of the substrate temperature during film deposition. (C) 1999 American Institute of Physics. [S1063-7834(99)02110-3].

Аннотация: For the first time the problem of determining real composition and structure of manganese ferrite nanoparticles dispersed borate glasses is solved using differentiating dissolution and high-resolution X-ray electron microscopy techniques. For the first time the nanosize effect of aluminum incorporation in manganese ferrite composition is experimentally shown, thus directly confirming the hypothesis of Al participation in exchange interaction between paramagnetic Fe and Mn ions as diamagnetic diluter.

Аннотация: Three results are presented. First, we prove the existence of a universal 7-cluster structure in all 143 completely sequenced bacterial genomes available in Genbank in August 2004, and explained its properties. The 7-cluster structure is responsible for the main part of sequence heterogeneity in bacterial genomes. In this sense, our 7 clusters is the basic model of bacterial genome sequence. We demonstrated that there are four basic "pure" types of this model, observed in nature: "parallel triangles", "perpendicular triangles", degenerated case and the flower-like type. Second, we answered the question: how big are the position-specific information and the contribution connected with correlations between nucleotide. The accuracy of the mean-field (context-free) approximation is estimated for bacterial genomes. We show that codon us-age of bacterial genomes is a multi-linear function of their genomic G+C-content with high accuracy (more precisely, by two similar functions, one for eubacterial genomes and the other one for archaea). Description of these two codon-usage trajectories is the third result. All 143 cluster animated 3D-scatters are collected in a database and is made available on our web-site: http://www.ihes.fr/similar to zinovyev/7clusters. (c) 2005 Elsevier B.V. All rights reserved.

Ключевые слова (''Своб.индексиров.''): calorimetry--composition--data reduction--lead compounds--mathematical models--permittivity--specific heat--adiabatic calorimetry--burns temperature--diffuse anomalies--barium compounds
Аннотация: The heat capacity of two relaxors BaTi(1-x)ZrxO(3) (x = 0.35, 0.40) was measured using adiabatic calorimetry in the temperature range 100-360 K. The Cp(T) dependence of both compositions is characterized by the presence of two diffuse anomalies near the Burns temperature T-d and the temperature of the maximum in permittivity T-m in the temperature ranges 250-350 K and 120 200 K. The anomalous heat capacity near T-d was analysed taking into account the distribution of Zr concentration in nanoregions leading to the distribution of their transition temperatures into the polar phase. Excess heat capacity near Tm was discussed in the framework of the spherical random bond-random field model. The results are compared with the data obtained by the same procedures for PbMg1/3Nb2/3O3 studied experimentally earlier.

Аннотация: A comparative study of file energies and the electronic structure of MgBx nanotubes is performed within the framework of the density functional theory. Different basic compositions (x = 2 for diboride and x = 3 for triboride) and different diameters (3 angstrom D 18 angstrom), as well the exterior, interior, and staggered placement of magnesium atoms, are considered. Energy analysis reveals a nontrivial bending behavior of the MgB2 sheets. such that the tubes with exterior and staggered configurations display the energy minima at certain small diameters (of the boron cage sublattice). The semiconducting behavior of narrow MgB2 nanotubes with exterior Mg position was observed.
