Modified nanooxides and related composites for various applications

According to the materials of scientific report at the meeting of the Presidium of NAS of Ukraine, November 8, 2017

Abstract

In the presentation, results of investigations of the characteristics and properties of initial and modified nanooxides and related composites, which can be used as adsorbents for industrial and medicinal usages, polymer fillers, catalysts, pigments, thickening agents, drug carriers, etc., are analyzed. Numerous experimental and theoretical methods were applied to nanooxides alone or with low- and high-molecular weight adsorbates and co-adsorbates in different dispersion media, gaseous, polar and nonpolar liquids, polymers over broad temperature ranges. To analyze the experimental data, original complex of computer programs was developed by the author of this presentation, including such methods as self-consistent regularization, maximal entropy method, functional minimization, etc. Some original techniques were developed to study the confined space effects, temperature, pressure, co-adsorption that it is important to evaluate the efficiency of the materials applications. Some versions of integral cryoporometry (based on TSDC, NMR, DSC) and thermoporometry (based on thermogravimetry) were developed to analyze the structural characteristics of various materials in different dispersion media.
