Graphene

Graphene is going to revolutionize the 21st Century

Graphene is a two dimensional material consisting of a single layer of carbon atoms arranged in a honeycomb or chicken wire structure. It is the thinnest material known and yet is also one of the strongest. It conducts electricity as efficiently as copper and outperforms all other materials as a conductor of heat. Graphene is almost completely transparent, yet so dense that even the smallest atom helium cannot pass through it....Read More >>  | University of Manchester

The Story of Graphene

Graphene is a fascinating material with many potential applications that stem from its unusual properties. It was thought not to be stable in its free form until it was isolated in 2004 by researchers at The University of Manchester. This is the story of how that discovery came about and why the researchers involved won the Nobel Prize in physics for their work.

If we stack layers of graphene on top of one another they form graphite, which is found in every pencil lead. In fact anyone who has drawn a line with a pencil has probably made some graphene. It was first studied as a limiting case for theoretical work on graphite by Phillip Wallace as long ago as 1947. The fact that electric current would be carried by effectively massless charge carriers in graphene was pointed out theoretically by Gordon Walter Semenoff , David P. DeVincenzo and Eugene J. Mele in 1984 and the name “graphene” was first mentioned in 1987 by S. Mouras and co-workers to describe the graphite layers that had various compounds inserted between them forming the so-called Graphite Intercallation Compounds or GIC’s.

The term has also been used extensively in the work on carbon nanotubes which are effectively rolled up graphene sheets. Attempts to grow graphene on other single crystal surfaces have been ongoing since the 1970’s, but strong interactions with the surface on which it was grown always prevented the true properties of graphene being measured experimentally....Read More  | Manchester University


Potential Applications

Several potential applications for graphene are under development, and many more have been proposed. These include lightweight, thin, flexible, yet durable display screens, electric circuits, and solar cells, as well as various medical, chemical and industrial processes enhanced or enabled by the use of new graphene materials.

So where will graphene take us? How will it change our world? What benefits will it bring to mankind in the near future and the decades to come?

Graphene. The world's first 2D material. Since its isolation in 2004 it has captured the attention of scientists and researchers worldwide. It is ultra-light, yet immensely tough. It is 200 times stronger than steel, but is incredibly flexible. It is fire resistant yet retains heat. It is a superb conductor, but not even helium can pass through it. All this and more. Much more.

When graphene is used alone or combined with other materials or substances the possibilities are infinite. It is a young material with the potential to create incredible future technologies and vastly enhance existing products. 

So where will graphene take us? How will it change our world? What benefits will it bring to mankind in the near future and the decades to come?

Graphene could revolutionise medicine. Nanotechnology is set to transform medical procedures. Drugs could be delivered to specific targeted cells. Graphene could pave the way for a step change in the treatment of cancer and conditions such as Parkinson's. Graphene has enormous potential when used as a membrane to separate liquids. It could see huge progress in water purification and treatment in developing countries, and even provide more efficient desalination plants. Graphene can make the world a safer place. In aircraft technology and cars. Through clothing for the defence industry. Graphene conducts. It means advanced paints could both reduce corrosion and increase energy efficiency.

Graphene detects. It could create sensors that can detect even minute traces of gases or dangerous chemicals, or sustainable food packaging that can let you know when food has gone off. Graphene absorbs light and retains it as energy. Add this to its strength and flexibility and bendable mobile phones and cameras with enormous battery life are ever closer. So are wearable electronics, clothing that communicates. These are future technologies which are becoming realistic in our present. Graphene has low  weight and high strength. Harnessed with polymers and composites it could make numerous forms of transport safer and more fuel efficient.Source:http://www.graphene.manchester.ac.uk
