AS IT IS 2016-10-05 Nobel in Chemistry Goes to Makers 1 of “World’s Smallest Machines” 2016诺贝尔化学奖:世界上最小的机器
Three scientists have won the Nobel Prize in Chemistry for their work in developing tiny machines.
The three men are Jean-Pierre Sauvage, Sir James Fraser Stoddart and Bernard Feringa.
They designed extremely thin molecular 2 machines. The machines are said to be 1,000 times thinner than a single piece of hair and have parts that move when energy is added.
The Royal Swedish Academy 3 of Sciences said the scientists’ work could lead to developments in new materials and energy storage systems.
The science of making things unimaginably small is called nanotechnology. Nanotechnology gets its name from a measure of distance. A nanometer, or nano, is one-thousand-millionth of a meter, about the size of atoms and molecules 5.
Jean-Paul Sauvage of France is a retired 6 professor at the University of Strasbourg. He began the work on a molecular machine in 1983 when he successfully linked together two molecules shaped like a circle or ring. It marked the first time chemists were able to make a molecule 4 act in such a way.
Fraser Stoddart is a professor of chemistry at Northwestern University in the United States. In 1991, he built on Sauvage’s work. He found a way to move the molecular ring onto a molecular axle and was able to move the ring along the axle.
Bernard Feringa is a professor of organic 7 chemistry at the University of Groningen in the Netherlands. In 1999, he developed a molecular motor. It used a molecular blade 8 that turned continuously in the same direction.
Sara Snogerup Linse explained the importance of their work to reporters in Stockholm.
"Maybe this morning you ground your coffee, maybe you used a motorized vehicle to get here - you used man-made machines operating on the centimeter to meter length scale. It's been a dream of scientists for over half a century to take this development all the way down to the molecular scale - that's nanometers. A nanometer is one million times smaller than a millimeter 9..."
Snogerup Linse is chair of the Nobel Chemistry Committee.
Sauvage, Stoddart and Feringa will share a $930,000 prize for their work. They will also receive a medal and diploma at an award ceremony on December 10.
