Renormalization Group Method: Enhancement of the Sen-Basser Model of the Brain White Matter We have developed a renormalization group method in order to explore the influence of a large range of geometrical and physical microparameters on the effective diffusion coefficient. The main element of this method comprises of the renormalization of structural parameters from the micro- to the millimeter scale of the random multi-component white matter of the brain. Our approach enhances the Sen-Basser model of the brain white matter [Sen P. N., Basser P. J., Biophys. J., 89 (2005) 2927] by taking the influence of disorder into consideration and allowing quantitative investigation of the sensitivity of the effective diffusion coefficient to the variations of the dominant set of microparameters.

The development of bionanoscopy instrumental methods The development of instrumental methods of scanning probe microscopy over the three decades indicates the wide spreading of scanning probe microscopy in various areas of science and technology, such as physics, chemistry, biology, medicine, materials science, geology and others. Besides, transfer of macroscopic measurement techniques to the micro and nano-scale is the second tendency the modern use of scanning probe microscopy. These two trends, as a rule, go hand in hand, and their development strongly depends on another important factor – the development of research methods, including sample and substrate preparation, the choice of the microscope operation mode, processing, analysis and interpretation of the data obtained.

Advanced methods of high-speed probe microscopy for biomedicine and new functional materials One of the most difficult tasks is the visualization of moving biological objects in the high resolution mode without disturbance of their functions. Modern investigations proved that dynamic structure and morphology of the proteins and cells discovered by high-speed scanning probe microscopy (HSSPM) may present the unique information about functioning of different cell processes on the molecular level.

Modified cotton polyester fabric with nanostructured ferromagnetic microwire characterized by low flammability X-ray diffraction study of cotton polyester fabric with a nanostructured ferromagnetic microwire, which chemical composition was modified by impregnating it with an aqueous solution of calcium chloride salt has been performed. According to the results of the performed study, it was justified that such fabric was characterized by low flammability, which determines the prospects of using it as elements of barrier structures of rooms to be shielded against electromagnetic impact.

The quantification of thin film atomic layer deposition conformality in high aspect ratio nanostructures The problems and methods for the quantitative characterization of the conformality of thin films on the surfaces of high-aspect ratio nanostructures during atomic layer deposition (ALD) are considered. The author develops the previously proposed methodology for analyzing the conformity of thin films by chemical vapor deposition (CVD) and plasma-enhanced deposition (PECVD), and ALD. The methodology proposed by the author allows to perform an adequate assessment and quantitative comparison of the results for the device structures of varying complexity using different kinds and conditions of ALD method.

Modification of galvanic coating "tin-bismuth" by carbon nanotubes to improve the corrosive resistance The article presents research results of the effect of carbon nanotubes (trade mark "Taunit") on corrosion characteristics of electroplating coating with a tin-bismuth alloy (Sn–Bi) in 0,1 mol Na2SO4 solution. It was shown that additives reduce the corrosion potential down to 54%.
