Introduction to Graphene
…my consuming interest
Why be interested in graphene?
Who wouldn’t want to be interested in this, it is going to be revolutionary.
A new material, isolated in 2004, it is the strongest material ever measured, transparent, flexible, conducts electricity and heat better than copper and has the highest melting point. The uses for this stuff will be endless.
Now is a good time to be interested too. Graphene is starting to come out of the laboratory and find practical real-world applications.
It is already being used to give elite sports competitors and edge with graphene enhanced running shoes, rubber tyres for bikes that grip better and give faster lap times. Graphene is even making a discreet involvement in racing cars where it can make carbon fibre components stronger and lighter.
Graphene inks are being used to create electrically conductive patterns on textiles and other flexible materials; the smart clothing of the future will contain graphene.
Expect to hear of graphene in construction. It makes concrete stronger, It can even make concrete electrically conductive giving us roads and floors with built in heating and no wiring that can fail.
Graphene has a sister material, graphene oxide. The latest research shows that human cells can grow over graphene oxide scaffolds. This opens up the possibility to make new parts for our bodies. Even more exciting is the discovery that human nerve cells will regrow along guides made from graphene oxide.
And that is just the tip of the iceberg, see what I mean? Who wouldn’t want to be interested in graphene?

Our work editing the Nixene Journal means we keep track of developments in the world of graphene every month. Compiling and curating the articles provides a viewpoint that a small number of us share. We are publishing volume three this year and when I stop to reflect, I am amazed at the pace of developments
A new breakthrough in making graphene has been created by Professor Aldo Zarbin and his team at the Universidade Federal do Paraná in Brazil. The Royal Society of Chemistry published this work, you can find out the details at this hyperlink. As well as being an entirely new method for making graphene, this process seems to be
An international team led by Manchester University, UK has discovered a fascinating property of graphene oxide membranes. (one micron thick membrane made from graphene oxide (GO) with a flake size of approximately 10 μm). They found that water would pass through the membrane. However when they applied an electric current across the membrane the water flow
This is work done by a team at Louisiana State University in the USA. They found that laying graphene oxide on a patterned surface then exposing the material to bright flashes of light did two things. Firstly it reduced the graphene oxide back to graphene and this makes it electrically conductive. Secondly it exfoliated the
This is a combined effort of researchers from Australia India and Japan. The paper is available at this link. They looked at the way graphene oxide nanoplates (GO) interacted with water vapour. They observed that GO imparts a very high water uptake capacity up to 0.58 gram of water per gram of GO (g g-1)
This is work done by a team at the Institute of Advanced Composite Materials, Korea Institute of Science and Technology (KIST). Graphene is not a perfect conductor of electricity. So when you put an electric current through graphene it heats up a little. Put a lot of current though and it gets very hot and
