We are working on something awesome

Dear All ,
RAA team in Chemistry is thinking of increasing its reach and bringing to you new and better avenues of learning . We will be -
1) Giving you kits relating to certain experiments in chemistry which we demonstrated here .
2) Publicly sharing videos based on exciting experiments done by us which can be used by you .
3) Creating written material for free distribution pertaining to the above .
We would also like to launch a YouTube Channel for these videos and materials . We hope that with your good wishes , we succeed .
Till then , keep exploring , keep learning .

The Nobel Prize in Chemistry 2016 was awarded jointly to Jean-Pierre Sauvage, Sir J. Fraser Stoddart and Bernard L. Feringa "for the design and synthesis of molecular machines".

So , what is this about , let's tell you . 

They developed the world's smallest machines

A tiny lift, artificial muscles and minuscule motors. The Nobel Prize in Chemistry 2016 is awarded to Jean-Pierre Sauvage, Sir J. Fraser Stoddart and Bernard L. Feringa for their design and production of molecular machines. They have developed molecules with controllable movements, which can perform a task when energy is added.

The development of computing demonstrates how the miniaturisation of technology can lead to a revolution. The 2016 Nobel Laureates in Chemistry have miniaturised machines and taken chemistry to a new dimension.

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. Normally, molecules are joined by strong covalent bonds in which the atoms share electrons, but in the chain they were instead linked by a freer mechanical bond. For a machine to be able to perform a task it must consist of parts that can move relative to each other. The two interlocked rings fulfilled exactly this requirement.

The second step was taken by Fraser Stoddart in 1991, when he developed arotaxane. He threaded a molecular ring onto a thin molecular axle and demonstrated that the ring was able to move along the axle. Among his developments based on rotaxanes are a molecular lift, a molecular muscle and a molecule-based computer chip.

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 10,000 times bigger than the motor and also designed a nanocar.

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. In terms of development, the molecular motor is at the same stage as the electric motor was in the 1830s, when scientists displayed various spinning cranks and wheels, unaware that they would lead to washing machines, fans and food processors. Molecular machines will most likely be used in the development of things such as new materials, sensors and energy storage systems.

THIS IS AN IMMENSE BREAKTHROUGH IN THE WORLD OF NANO-SCIENCE . The vision of Prof Richard Feynman as envisioned in his lecture , " There's enough room at the bottom " , is becoming close to a reality . with these molecular machines , we can build miniature machines right down to molecular level which will help us to develop cure for many diseases which are currently incurable .
