The world is facing serious energy and environmental problems that will vastly threaten the quality of human life. Developments of new technologies that can minimize natural resource consumption and concurrently assure the continuous supply of green energy from renewable sources are highly needed. Research groups in the 'Energy/Green Tech' aim to respond to the global needs for human sustainability. The core of this research area is understanding the relationship between materials’ structure and their properties and ultimately developing new functional materials & devices for their applications in diverse energy and environmental technologies.
