Three scientists won the Nobel Prize in Chemistry yesterday for developing the world’s smallest machines, work that could revolutionize computer technology and lead to a new type of battery.
Frenchman Jean-Pierre Sauvage, British-born Fraser Stoddart and Dutch scientist Bernard “Ben” Feringa shared the 8 million kronor (US$930,000) prize for the “design and synthesis of molecular machines,” the Royal Swedish Academy of Sciences said.
Machines at the molecular level are one-1,000th the width of a human hair and have taken chemistry to a new dimension, the academy said.
Molecular machines “will most likely be used in the development of things such as new materials, sensors and energy-storage systems,” it said.
Stoddart has already developed a molecule-based computer chip with a 20kB memory. Researchers believe chips so small could revolutionize computer technology the way silicon-based transistors once did, the academy said.
It said the laureates’ work has also inspired other researchers to build increasingly advanced molecular machinery, including “a robot that can grasp and connect amino acids” in 2013.
Researchers are also hoping to develop a new kind of battery using the technology.
Sauvage, 71, is professor emeritus at the University of Strasbourg and director of research emeritus at France’s National Center for Scientific Research.
Sauvage’s wife choked back tears as she absorbed the news.
“Jean-Pierre won the Nobel prize,” she said, her voice trembling as she spoke on multiple telephones at once ringing with news of the prize.
Officials at the University of Strasbourg, where Sauvage is a professor emeritus in the Institute of Science and Supramolecular Engineering, were overwhelmed and honored by the news, and said they were trying to reach him to celebrate his victory.
Stoddart, 74, is a chemistry professor at Northwestern University in Evanston, Illinois.
His daughter, Alison, said he was “absolutely ecstatic” at the honor.
Feringa, 65, is a professor of organic chemistry at the University of Groningen in the Netherlands.
“I don’t know what to say, I’m a bit shocked,” Feringa told reporters in Stockholm by telephone. “I’m so honored and I’m also emotional about it.”
Molecular machines are molecules with controllable movements that can perform a task when energy is added, the academy said.
It said Sauvage made the first breakthrough in 1983 when he linked two ring-shaped molecules together to form a chain.
Stoddart took the next step in 1991 by threading a molecular ring onto a molecular axle, while Feringa was the first to develop a molecular motor in 1999 when he got a molecular rotor blade to spin continuously in the same direction.
The academy said the molecular motor is at the same stage now as the electric motor was in the 1830s.
The Nobel Peace Prize is to be announced tomorrow, while the economics and literature awards are to be announced next week.
The prizes are to be handed out at ceremonies in Stockholm and Oslo on Dec. 10, the anniversary of prize founder Alfred Nobel’s death in 1896.
CLOSE ENCOUNTERS: Several of the PLA fighter jets that crossed the median line of the Strait came within 68km of Hsinchu, drawing warnings from Taiwan, the ministry said At least 18 Chinese military aircraft yesterday flew into the nation’s air defense identification zone (ADIZ) on the second day of a US delegation’s visit, the Ministry of National Defense said, adding that the military responded by deploying an air defense missile system to monitor their activities. A delegation led by US Undersecretary of State for Economic Growth, Energy and the Environment Keith Krach on Thursday started a three-day visit to Taiwan. The ministry from Thursday started publicizing the actions of the Chinese People’s Liberation Army (PLA) in Taiwan’s ADIZ on its Web site and Twitter. According to ministry reports, 18 PLA aircraft
TWO CASES: The five allegedly conspired with conglomerates, threatening the nation’s governance and subverting the rules of ethical conduct, a deputy chief prosecutor said Taipei prosecutors yesterday charged three legislators and one former lawmaker with contravening the Anti-Corruption Act (貪污治罪條例) in a case linked to former Pacific Distribution Investment Co (太平洋流通) chairman Lee Heng-lung’s (李恆隆) battle with the Far Eastern Group (遠東集團) over ownership of the Pacific SOGO Department Store (太平洋崇光百貨) chain, while independent Legislator Chao Cheng-yu (趙正宇) was indicted in a separate case involving two funeral services companies and a plot of land in a national park. Chinese Nationalist Party (KMT) legislators Chen Chao-ming (陳超明) and Sufin Siluko (廖國棟), Democratic Progressive Party (DPP) Legislator Su Chen-ching (蘇震清) and former New Power Party legislator
Swedish Member of Parliament Hampus Hagman is pushing for changing the name of the nation’s trade office in Taipei to signal improved relations with “Asia’s perhaps foremost democracy.” Hagman on Wednesday last week proposed renaming the Swedish Trade and Invest Council to “Sweden’s Office in Taipei,” following similar changes by other nations. The Swedish Trade and Invest Council, part of Business Sweden, is owned by the Swedish government and Swedish industry. Taiwan and Sweden share important values such as respect for democracy, human rights, the rule of law and freedom of speech, Hagman said in the motion, adding that the two nations
PENGHU INSPECTION: Taiwan cannot let its enemies strut around in its airspace, Tsai said, one day after a Chinese spokesman denied a median line exists in the Taiwan Strait Following China’s assertion on Monday that there is no “median line” in the Taiwan Strait, President Tsai Ing-wen (蔡英文) yesterday pledged to defend the nation’s airspace during a visit to an air force base in Penghu, saying that Taiwan cannot allow others to flex their military muscle in its territorial airspace. Tsai praised the “heroic performance” of the pilots of the Indigenous Defense Fighters who have been intercepting Chinese People’s Liberation Army Air Force planes in recent days. “I have a lot of confidence in you. As soldiers of the Republic of China [ROC], how could we let enemies strut
