Conducting Composite Material Based on Chitosan and Single-Wall Carbon Nanotubes for Cellular Technologies.

Biocompatible electrically conducting chitosan-based films filled with single-wall carbon nanotubes were obtained. Atomic force microscopic studies of the free surface topography revealed a change in the morphology of chitosan films filled with single-wall carbon nanotubes. Introducing 0.

Dependence of the value of the atomic magnetic moment of d metals on the chemical structure of nanoforms.

The X-ray photoelectron spectroscopy was used for studying the dependence of the 3d-metal spin state in nanoforms on the nanoform chemical structure. For studying the nanoform chemical structure a model developed by us was used, which allowed to find out the interrelation between the parameters of the X-ray electron 3s spectra of transition metals and the number of uncompensated electrons in metal atoms. It is shown that the nanoform chemical structure is determined by the methods used for their preparation and by the nanoreactor form.

Investigations of porous silicon with deposited 3D-metals by Auger- and ultrasoft X-ray emission spectroscopy.

Nanocomposites based on porous silicon (Por-Si) with 3d-metals incorporated into pores can be used as magnetics. Por-Si layers were obtained by anodic etching of n-type silicon (100) with the use of HF solution in alcohol. Fe, Co, Ni galvanic deposition in por-Si was made from aqueous solutions of corresponding sulphates.

[Functional organization of the brain cortical areas at rest condition in children 5, 6 and 7 years old].

Functional connectivity at rest was studied in children of 5, 6 and 7 years old. Connection strengths were estimated using coherence function taken at the frequencies of the major EEG rhythms. Factor analysis of the raw coherence data revealed 4 different cortico-cortical functional connectivity patterns.
