"Graphene can be used for many different purposes including:

Transistors
Graphene can be used to make excellent transistors. It is so thin we can easily control whether or not it conducts by applying an electric field. We would like to be able to do this with metals, but we cannot make metal films thin enough to affect their conducting state in this way. Electrons in graphene also travel ballistically over sub-micron distances. As a result, graphene-based transistors can run at higher frequencies and more efficiently that the silicon transistors we use now. At the present moment we have no way to produce entire integrated circuits from these transistors since we are limited by the size of graphenes we can produce.

Gas Sensors
Gas molecules that land on graphene affect its electronic properties in a measurable way - in fact, we have measured the effect of a single molecule associating with a graphene. This means that we can create gas sensors which are sensitive to a single atom or molecule!

Support Membranes for Transmission Electron Microscopy
Graphene is effectively the thinnest material that we can make out of atoms. Suprisingly it is also very strong, thanks to a lack of crystal boundaries to break along and very strong bonds between carbon atoms (Carbon nanotubes are made from rolled up graphene, and it has been suggested that cabling made from nanotubes would be strong enough to create an elevator into space!). As a result we can use it to hold micro- and nanoscopic objects we wish to look at in an electron microscope (e.g. DNA, nanoparticles) in a similar way we use glass slides in an optical microscope. Graphene is the perfect material for this job as it is made only of carbon, it is very thin so will not interfere with the pictures taken as much as other materials, and has a very simple crystal structure so can easily be eliminated from diffraction patterns.

Inert Coatings
Graphene is resistant to attack by many powerful acids and alkalis such as hydrofluoric acid and ammonia, so one day could be used to give objects an atomically thin protective coating which would provide protection against these agents.

Although it will likely be many years before we see any of these applications fully realised, the discovery of graphene has provided an unparalleled opportunity for scientists to investigate these possibilities."


Comment
So can this material be used to reduce carbon??
I like the gas sensor. Mine safety and pollution monitoring?
