The TwinTeam aims to build a training and research network with a focus on the newly emerged theme: materials chemistry enabling clean technologies. Starting from exploration of surface/interface phenomena and going to materials performance via detailed knowledge on materials properties at a nano-scale, the network has a potential to address challenging key technologies such as “greener and safer” energy storage, catalytic/adsorption processes for neutralization of pollutants and conversion of CO2, glasses/bioceramics products for better life/health. This will be achieved through forging of effective and long-lasting twinning between the Institute of General and Inorganic Chemistry (IGIC) and leading European scientific organizations: Imperial College London, Karlsruhe Institute of Technology and University of Seville. The specific objectives are to develop and to take to next level IGIC scientific, technological and management capacity, to raise the research portfolio of IGIC by thematic, soft skills and research management training, and to strengthen the IGIC staff by retention of qualified scientists and attracting new young scientists.
