To survive in the world we have transformed we must learn to think in a new way J. C. Polanyi
The Institute of Materials and Environmental Chemistry, Chemical Research Center, Hungarian Academy of Sciences is a non-profit oriented research
institute. Within the Center, IMEC is independent in terms of its scientific affairs and financial activities.
The mission of IMEC CRC HAS is to perform research on the chemical problems of materials science and environmental science. Research in materials chemistry is aiming at revealing the chemical relationships among the composition, microstructure, properties and processing of selected structural and functional materials, as models. Research in environmental chemistry is dedicated to disclose basic chemical and physicochemical phenomena in order to decrease the environmental impacts of products and technologies on the one hand, and to develop new processes and technologies with a minimum or negligible environmental impact on the other.

Physical chemistry research related to issues of great importance in environmental protection and sustainable development is done as follows:
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.
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.
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.
