The problem with commercializing graphene that is synthesized onto metals over a wide area is that it can not be separated from the metal. However, a groundbreaking separation technology which is both cheap and environmentally friendly has been developed.
A North Carolina State University researcher has developed a more efficient, less expensive way of cooling electronic devices – particularly devices that generate a lot of heat, such as lasers and power devices.
The technique uses a “heat spreader” made of a copper-graphene composite, which is attached to the electronic device using an indium-graphene interface film.
Despite the recent research on bacterial production techniques it has long been known that graphene possesses anti-bacterial qualities. As far back as July 2010 a study conducted by Chunhai Fan, a professor in the Laboratory of Physical Biology at the Shanghai Institute of Applied Physics, showed that as well as being anti-bacterial graphene derivatives had the added benefit of being bio-compatible with human cells.
Now, twenty two months later, a team of scientists headed by Bingan Lu of Lanzhou University have shown that graphene combines with chitosan, a blood clotting agent, to produce a wound dressing that significantly reduces the time it takes for a wound to completely heal.
The UK’s leading manufacturer of high purity single-wall carbon nanotubes, Thomas Swan & Co. Ltd, has announced a 4 year, £625K collaboration with the Centre for Research on Adaptive Nanostructures and Nanodevices (CRANN) at Trinity College Dublin to develop a scalable manufacturing process for high purity graphene.
The 4 year collaboration with CRANN, the Science Foundation Ireland (SFI) funded nanoscience institute based at Trinity College Dublin, will focus on the industrial scale-up of consistent, high purity graphene production.
