Specifications of Gallium Metal

*In 1875 in Paris, Paul E. Lecoq de Boisbaudran discovered Gallium metal which has the chemical symbol of Ga. *Atomic weight of this silvery-blue metal is 69.723 and Gallium is included in other metals group.  *Gallium element is considered to be non –toxic and no important harmful effect has been detected in industrial usage.  *Gallium element is a silvery, glass-like, soft metal and in periodic table it is very close to nonmetals. Gallium is one of a few metals which have liquid form.  *Gallium melting point 29.76 °C . So, Gallium element is liquescent in room temperatures.  *Just like water, gallium also becomes larger when it freezes.  *Gallium material is very useful in Surgical Instruments Manufacturing and health applications. Gallium metal may also be used in different alloys.  *Gallium arsenide is a very important substance for the production activities of semiconductors.  http://nanografi.com/special-materials/gallium-99-99-metals-basis/ ...

No friction with the help of GRAPHENE!

It was known that diamonds are already one of the hardest natural substances. But if diamoınd combine with graphene, nanoparticles can be slippery and it can be useful if you want to reduce friction in a moving machine. Scientist showed that the combination of tiny bits of diamond and graphene that had superlubricity. This means that the friction between them and another object dropped to near zero. Reducing friction, or making things more slippery could have benefits beyond just making it easier for objects to move around. For example "nearly one-third of a vehicle's fuel energy is spent on overcoming engine, transmission, and tire friction." Reduce the friction, reduce the amount of fuel used. Diamond nanoparticles contact with the thin sheets of graphene and the graphene rolled up around the diamond nanoparticles, creating scroll or ball like structures. This specific structure makes the superlubricity possible right now, but researchers hope that they can e...
