Dr. Bard is very knowledgeable in electrochemistry and has taught us a lot by giving us interesting classes and flexible homework. Dr. Goodenough, actually, he is working in the office 10 m from our lab on 9th floor. His revolutionary Li-ion battery cathode material offers a novel concept for portable electronics.
