Extractions: November 2000 Dr. Shirakawa of Japan Awarded Nobel Prize for Chemistry T he Royal Swedish Academy of Sciences on October 12 announced the awarding of the Nobel Prize for Chemistry to Hideki Shirakawa of Japan and two Americans for their "revolutionary discovery" that plastic can be made electrically conductive. S hirakawa, 64, a professor emeritus at the University of Tsukuba , was chosen the Nobel laureates along with Alan J. Heeger, 64, of the University of California at Santa Barbara, and Alan G. MacDiarmid, 73, of the University of Pennsylvania. The three researchers will share the prize money of 9 million Swedish kronor (about 100 million yen). T he academy, according to the citation, named them for the "discovery and development of conductive polymers" that are now in use in such things as antistatic substances for photographic film, computer screen shields, and small television and cell phone display monitors, reversing the conventional belief that plastics, unlike metals, cannot conduct electricity. S hirakawa is the ninth Japanese Nobel laureate and the second to receive the prize for chemistry after Kenichi Fukui in 1981. The son of a practicing doctor in Gifu Prefecture, central Japan, Shirakawa liked science most among school subjects and got high marks in it. "I was interested in how to make various kinds of plastics" that found their way into people's daily life in the postwar period, he said.
Extractions: Mr. Oshima, Minister of Education and Minister of STA, expressed on October 10 his opinion applauding the remarkable achievements of Dr. Shirakawa. Dr. Shirakawa was the 9th Japanese Nobel Prize laureate following Mr. Kenzaburo Oe who won in literature in 1994, and the 2nd in chemistry following Mr. Ken-ichi Fukui (deceased) in 1981.

Nobel Focus: Electricity Through Plastic The chemistry nobel Prize this year went to Alan Heeger, Alan MacDiarmid, and HidekiShirakawa for the discovery and development of electrically conductive http://focus.aps.org/story/v6/st18/
Extractions: The chemistry Nobel Prize this year went to Alan Heeger, Alan MacDiarmid, and Hideki Shirakawa "for the discovery and development of electrically conductive polymers." The laureates first described the details of their discovery in PRL in 1977, 23 year ago today. At the time, plastics were considered nonconductors, but the team showed that adding some impurities to a polymer material could increase its conductivity by more than a billion times. Their work led to the field of plastic electronics, which has resulted in several commercial applications. But they also helped to spur new areas of fundamental research in condensed matter physics by demonstrating some exotic polymer properties, such as charge carriers that, unlike electrons, have zero spin. Plastics are so dependable as insulators (materials that don't conduct electricity) that they are often used for the protective coatings around wires. By the 1970s chemists had worked with some small organic molecules that could conduct, but a conducting, carbon-based, long-chain molecule was something "no one had really contemplated," recalls Richard Friend of the University of Cambridge in the UK. Polymers were known to be far cheaper to process than conventional electronics materials, which is one reason the results had "a huge impact," says Friend.

Extractions: Close this window to return to the previous window Box 2 Japan seeks a record haul In December 2000, as part of its Science and Technology Basic Plan, the Japanese government set its scientists an ambitious goal: 30 Nobel prizes in the next 50 years. This would mean a fivefold increase in the success rate experienced over the past half-century. But the plan has at least sparked a debate on why Japanese scientists are so poorly represented in the ranks of Nobel laureates. Some Japanese scientists argue that the problem is a fundamental lack of creativity, stemming from an educational and social system that promotes rote learning and conformity. But James Bartholomew, a historian of Japanese science at Ohio State University in Columbus, rejects this self-deprecating stereotype. "The image of the Japanese as unoriginal is unfounded," he says. AP Hideki Shirakawa receiving his chemistry Nobel last year. Nevertheless, many researchers believe that Japan's academic ' koza ' system, which places immense power in the hands of university professors and limits the freedom of younger investigators to set their own research agendas, has a stifling effect. "Everyone in our lab had to do projects dictated by our professor," says one molecular biologist, now in the United States. "But we each had our own 'shadow projects', which we could only work on when he was not around." Hideki Shirakawa of the University of Tsukuba, who shared last year's chemistry Nobel for his work on electrically conducting organic polymers, argues that improving the situation may require changes to the laws that govern Japan's public university system. "Younger scientists have a very restricted range at universities," he says. "They have no chance to change supervisors unless they go abroad."

Extractions: STOCKHOLM, Sweden (AP) - Americans Alan J. Heeger and Alan G. MacDiarmid and Hideki Shirakawa of Japan won the Nobel Prize in chemistry Tuesday for their discoveries that plastic can be made electrically conductive - an advance that has led to improvements in film, TV screens and windows. The laureates will share the $915,000 prize for the "discovery and development of conductive polymers," according to the citation by the Royal Swedish Academy of Sciences. Heeger, 64, of the University of California at Santa Barbara, MacDiarmid, 73, of the University of Pennsylvania and Shirakawa, 64, of the University of Tsukuba learned that plastics can, with modifications, be made to conduct electricity as well as insulate. The three developed conductive polymers that have been used to reduce static electricity and interference on photographic film and computer screens. The plastics have also been used in the development of new color television screens and "smart windows" that reflect sunlight.
