Pylypchuk I. Synthesis and properties of magnetosensitive Gd-containing nanocomposites

The thesis is devoted to the development of chemical processes synthesis of multifunctional magnetosensitive Gd-containing nanocomposites. It was synthesized various types of nanocomposites with core / shell structure, based on magnetite.On the surface immobilized borate, oxide and ferrite of gadolinium and dimerkaptosuccinic dyetylentriaminpentaacetic acid with their subsequent binding with gadolinium ions. Investigated their physical and chemical properties identify common patterns of physical and chemical processes that occur during the synthesis. Object of research - synthesis of multifunctional Gd-containing nanocomposites. Purpose of the study -study the influence of synthesis conditions and / or surface modification on their physicochemical properties (content of neutron capture agent's, ability to adsorb cations, magnetic properties, etc..) The following research methods was used: transmission electron microscopy, X-ray analysis, X-ray photoelectron spectroscopy, vibrating magnetometry, Fourier transform infrared spectroscopy, spectrophotometric analysis, atomic emission spectrometry with inductively coupled plasma.
