Graphene: Are We About to Enter the Carbon Age?

Indeed. But we are still far away from the fabrication technology that will allow us to make pure and continuous lengths of multiwalled Carbon nanatubes. hehehe

give and take 50 yrs, kaya or dili? basin pwedi na sad no? hehehe...

A little update on patenting graphene:

Not exactly. The bonding structure of graphene is sp2 hybridization. As consequence, each Carbon atom is surrounded by 3 other Carbon atoms. This basically means that there is an electron that can free move around like a metal or as a semiconductor or a semimetal. This is why graphene has very interesting electronic properties.

Diamond has sp3 hybridaztion. This means that each Carbon is surrounded by 4 Carbon atoms. Each of its lone pair electron is really bonded into another Carbon via Orbital Hybridization. For those who took Chemistry 101 course, this is one of the basic topics in chemical bonding. hehe! Anyway, what it means is that diamond is a pure insulator is insanely strong due to nature of the bonds of all four surrounding Carbon atoms. These bonds are called sigma bond is very very strong.

Graphene on the other hand as I mention has sp2 hybridazation and only 3 Carbon atoms surrounding one Carbon atoms. These bonds are composed of 3 sigma bonds and 1 pi bond. Pi bonds are significantly weaker than sigma bonds. For this reason, Diamond is much stronger than Graphene. However, with just 3 sigma bonds and 1 pi bonds, Graphene can still be rolled into Carbon nanotubes that have incredible tensile strength. The bonding between Carbon atoms in Graphene is really strong compare to other materials.

practically invisible and 100x stronger than metal? not bad..

I think you're right. Not sure about 100x though but it is definitely very strong. hehehe

Graphene - i love this post.. thanks TS!

[neoraising]

the future of electronics..

[freez3]

carbon is the new frontier... from carbon-based transistors to graphene... wow... adto nata carbon nah.
verrry promising!
