Andre Geim and Konstantin Novoselov talk about scalable production and the future viability of graphene products.
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.
XG Sciences, a privately owned corporation based in Michigan, has announced it has been selected by the Air Force Research Laboratory to develop ultra high-energy graphene ultracapacitors for use in space energy storage systems. XGSs’ graphene-based energy storage materials have demonstrated significant increases in storage capacity over traditional activated carbon and are manufactured in a commercially-proven, environmentally friendly, low-cost process.
Graphene could be the superhero of materials – it’s light, strong and conducts heat and electricity effectively, which makes it a great material for potential use in all kinds of electronics. And because it’s made from carbon atoms, graphene is cheap and plentiful. Its electric and mechanical properties also affect one another in unique ways. But before freestanding graphene can live up to its potential, scientists need to be able to control these properties.
