About Hideki Shirakawa, Nobel Prize in Chemistry, 2000
Hideki Shirakawa (白川 英樹 Shirakawa Hideki, born in Tokyo on August 20, 1936) is a Japanese chemist and winner of the 2000 Nobel Prize in Chemistry for his discovery of conductive polymers together with physics professor Alan J. Heeger and chemistry professor Alan G. MacDiarmid at the University of Pennsylvania.
While employed as an assistant at Tokyo Institute of Technology (Tokyo Tech) in Japan, he developed polyacetylene, which has a metallic appearance. This result interested Alan MacDiarmid when MacDiarmid visited TITech in 1975.
In 1976, he was invited to work in the laboratory of Alan MacDiarmid as a post-doctoral fellow at the University of Pennsylvania. The two developed the electrical conductivity of polyacetylene along with American physicist Alan Heeger.
In 1977 they discovered that doping with iodine vapor could enhance the conductivity of polyacetylene. The three scientists were awarded the Nobel Prize in Chemistry in 2000 in recognition of the discovery. With regard to the mechanism of electric conduction, it is strongly believed that nonlinear excitations in the form of solitons play a role.  Biography
