4 Environmental Chemistry Physical chemistry research related to issues of great importance in environmental protection and sustainable development is done as follows: Environmental Protection The main fields of activity within the framework of analytical and technological research and development are the following: Thermal decomposition studies of biomass, solid fuels and polymers are carried out for characterizing their thermal stability and pyrolysis kinetics. The thermal decomposition, temperature-controlled combustion and gasification of biomass materials are investigated with a view to their energy industry use. The study of pyrolysis of polymers aspires toward the environmental-friendly recycling of plastics wastes. Chemical analysis in the fields of environmental protection The atmospheric chemistry studies are aimed at understanding the processess and phenomena that play important roles in the interplay between climate change and the chemistry of the environment. The kinetics of key uni- and bimolecular elementary reactions are investigated that have relevance to the formation and further fate of reactive greenhouse gases in the atmosphere, the combustion chemistry of atmospheric fires, and alternative fuels. Additional photochemical studies are related to practical chemistry problems of the aquatic environment and to the photo-transformation of airborne organic aerosols. Corrosion protection by inhibitors The electrochemistry studies target the elaboration of methods for removing certain pollutants from ground water. The related electrochemical kinetics problems, like electrocatalysis, corrosion properties of metals, inhibitors, conversion layers, and polymer coatings are studied by impedance spectroscopy and similar methods; the necessary, highly sensitive instruments have been being developed in our laboratory.
