05 October 2016 Current Affairs GK: The 2016 Nobel Prize in Chemistry was awarded to Jean-Pierre Sauvage, Sir James Fraser Stoddart and Bernard L Feringa on 5 October 2016.
The trio were bestowed with the prestigious award for the design and synthesis of molecular machines.
Jean-Pierre Sauvage is a French coordination chemist. Sir James Fraser Stoddart is a Scottish chemist. He works in the area of supramolecular chemistry and nanotechnology. Bernard L Feringa is a synthetic organic chemist, specializing in molecular nanotechnology and homogenous catalysis.
Jean-Pierre Sauvage, Sir James Fraser Stoddart and Bernard L Feringa have developed molecules with controllable movements, which can perform a task when energy is added.
The first step towards a molecular machine was taken by Jean-Pierre Sauvage in 1983, when he succeeded in linking two ring-shaped molecules together to form a chain, called a catenane.The second step was taken by Fraser Stoddart in 1991, when he developed a rotaxane. He threaded a molecular ring onto a thin molecular axle and demonstrated that the ring was able to move along the axle.
Bernard Feringa was the first person to develop a molecular motor. In 1999, he got a molecular rotor blade to spin continually in the same direction. Using molecular motors, he has rotated a glass cylinder that is 10000 times bigger than the motor and also designed a nanocar.The 2016's Nobel Laureates in Chemistry have taken molecular systems out of equilibrium's stalemate and into energy-filled states in which their movements can be controlled.
