Prof. C.A.N. Fernando discusses the applications of nano technology for energy and the environment. Some key applications discussed include using nano materials like graphene, titanium dioxide, and activated carbon in solar cells to increase efficiency and lower costs. Activated carbon produced from natural precursors like coconut shells, palm leaves, and bamboo can be used for water purification, air purification, and treating textile effluents. The document also briefly mentions using semi-conductors in ultrafast transistors, biosensors, solar cells, batteries, fuel cells, and super capacitors. It concludes with a short list of renewable and non-renewable energy sources as well as transportation and distributed generation.
