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 …
This is work done by a joint Chinese and American team. They have glued together graphene nanoplates to make a composite that does not need carbon fibre. The graphic shows the steps they had to go through to make this work. The resulting composite conducted electricity and was fairly strong with a tensile strength of …

This is research done by a team at Chalmers University in Sweden.They made graphene spikes that were 60 to 100nm high form vertically from a surface by plasma deposition. They found these spikes stopped bacterial biofilms forming by puncturing thecell walls. Human cells were much larger and so not affected by the spikes. At one …
MIT’s roll-to-roll process making CVD graphene Massachusetts Institute of Technology (MIT) first announced their work making graphene by a continuous process back in 2015. It is a measure of just how difficult this is in practise that over three years later the team is still developing the process. They are making good progress though. Now …
This month a team at UNIST in Korea posted their understanding of how to perfect graphene growth. Perfect sheets of graphene (single crystal graphene) is important for making next generation electronic devices among many other things. To make wrinkle free single crystal graphene, first make the single crystal copper surface on which it can grow. …
I’m a strategic facilitator. That means I help organisations to think about their futures and create action plans. Usually I’m designing and delivering strategy events that enable boards and their senior management teams do this future planning. Over the past few months I’ve been juggling this day job and also applying these techniques to my …
