Japanese scientist Shirakawa, co-winner of 2000 Nobel Prize in chemistry, dies at 90

Japanese scientist Hideki Shirakawa, a co-winner of the 2000 Nobel Prize in Chemistry, passed away at the age of 90. The Nobel-winning discovery was made in collaboration with two American scientists, Alan Heeger and Alan MacDiarmid. Their groundbreaking work demonstrated that plastic could conduct electricity like metal, leading to the development of conductive polymers with applications in electronics.

Shirakawa taught and conducted research at the University of Tsukuba after joining in 1979. He was born in Tokyo in 1936 and earned his doctoral degree in engineering from the Tokyo Institute of Technology in 1966.
