Japan's Kitagawa shares this year's Nobel Prize in Chemistry with two others

Japanese scientist Kitagawa Susumu is one of the three winners of this year's Nobel Prize in Chemistry for creating molecular constructions, called metal-organic frameworks.

The Royal Swedish Academy of Sciences made the announcement on Wednesday. Kitagawa, executive vice-president of Kyoto University, shared the prize with Richard Robson from University of Melbourne, and Omar Yaghi from University of California.

At a news conference at Kyoto University after the award announcement, Kitagawa said what he has engaged in is creating new materials and developing materials with new functions. He said that it is a great joy for scientists to challenge new frontiers, and he has enjoyed doing what he did for the past 30 years or so.
