There has been quite the buzz around graphene lately. With this material being among the strongest and most lightweight known, it has the potential to revolutionize industries from healthcare to electronics. And revolutionize is exactly what the Cambridge Graphene Centre (CGC) and Plastic Logic have set out to do.

With the CGC’s graphene expertise and Plastic Logic’s already developed technology for flexible electronics, the two came together to demonstrate the first graphene-based flexible display.

This from University of Cambridge:

The new prototype is an active matrix electrophoretic display, similar to the screens used in today’s e-readers, except it is made of flexible plastic instead of glass. In contrast to conventional displays, the pixel electronics, or backplane, of this display includes a solution-processed graphene electrode, which replaces the sputtered metal electrode layer within Plastic Logic’s conventional devices, bringing product and process benefits.

What’s Graphene?

Kostya Novoselov

Published over 60 peer-refereed research papers (mainly as the principal/corresponding author) including Nature and Science articles and more than 15 papers in Nature Materials, Nature Physics, Nature Nanotechnology, Reviews of Modern Physics, Physical Review Letters, PNAS.

We’ve been having lots of talks around the home office about how people don’t realize the impact of electrochemistry and solid state science have on their world.

Being new here, I’m still playing catch up with the science. I ask a lot of questions. My colleagues patiently try to do what Miss Lemke could never accomplish in 11th grade chemistry.

Here’s one result that can benefit me and the rest of our less aware readers of this blog. I got this video link explaining graphene from John Lewis, our Associate Director of Publications. The video is from The One Show, BBC1 last year.

Using Hemp to Store Energy

“People ask me: why hemp? I say, why not?”

That is what Dr. David Mitlin said about the new discovery in bio-waste that has been published in the journal ACS Nano, according to BBC.

Mitlin and his team presented their findings at the American Chemical Society meeting in San Francisco, where it was explained how waste fibres from hemp can be transformed into high performance energy storage devices.

The hemp – which is legal to grow due to the absence of THC – is producing supercapacitors that are at least on par with the graphene, which is known to be the industry’s gold standard.

Dr. Mitlin and his researchers primary focusing on taking produces that are considered waste and evolving them into something applicable and with high value.

This from BBC:

But the leftover bast fibre – the inner bark – typically ends up as landfill. Dr Mitlin’s team took these fibres and recycled them into supercapacitors – energy storage devices which are transforming the way electronics are powered.
