Partial case of thermochemical analysis of cavitation sonolysis of water

The mechanism of water sonolysis with the formation of both intermediates (free radicals) and basic products (hydrogen and oxygen), which are important for thermal power engineering and water purification technologies, based on the use of advanced oxidation processes, wasresearched. The efficiency of hydroxyl radical generation in the environment of inert gases and oxygen was analyzed.

Polymers in polluted atmosphere. Free radical and ion-radical conversions initiated by nitrogen oxides

Nitric oxide, nitrogen dioxide, nitrogen trioxide as well as dimers of nitrogen dioxide are reactive initiators of radical transformations of macromolecules and modifying reactants for polymers. Features of the initiation mechanism determining the composition of molecular and radical products in polymers under the action of nitrogen oxides are discussed.
