Application of nitroxyl radicals to study mass transfer processes in porous materials

A method to determine rates for gaseous and liquid transfer of moisture in the process of mass transfer in porous materials is suggested. The data obtained agree well with the theoretical concepts about liquid transfer of moisture under contact of two porous bodies.

Texture and surface properties of carbon-silica nanocomposite materials prepared by the carbonization of high-ash vegetable raw materials in a fluidized catalyst bed

A series of carbon-silica nanocomposite samples prepared by the carbonization of high-ash biomass (using rice husks as an example) in a fluidized-bed reactor with a deep oxidation catalyst at 450–600°C was studied by a set of physicochemical techniques (BET, IR spectroscopy, XPS, and TGA). The dependence of the chemical composition, texture characteristics, and main properties of the resulting materials on carbonization temperature was found.
