Researchers from Rice University created thin hybrid metal-graphene electrodes - that outperform ITO electrodes, are also more transparent and less resistance to electric current. These electrodes can be used to create non-glass touch displays, transparent and flexible OLEDs, solar cells and lighting products.

The new electrode is a thin film of single-layer graphene and a fine grid of metal nanowire. It's basically a hybrid-graphene electrode. The metal is used to enhance the conductivity at the required transparency. The metal grid strengthens the graphene, and the graphene fills all the empty spaces between the grid. The researchers found a grid of five-micron nanowires made of inexpensive, lightweight aluminum did not detract from the material's transparency.

Andre Geim from the University of Manchester UK (the 2010 Nobel prize in Physics winner) gives a great lecture on Graphene - starting with an introduction and then giving updates from their latest research:

Nokia posted an interesting blog post today about Graphene. It turns out that the Nokia Research Center is part of Graphene-CA, the EU's ambitious 10-year 1 billion Euro research initiative. Apparently Nokia is quite excited about the new 'super' material - which enable new devices - such as the Morph concept shown below:

Researchers from Turkey's Bilkent University discovered that graphene oxide can be reversibly reduced and oxidized using electrical stimulus. They say that graphene's band structure can be electrochemically tuned in ambient air in a two terminal planar device (due to humidity in the air). The researchers claim that if this effect can be better controlled, you could use this to create E Ink like e-paper that will be ultrafast. This could also have applications in information processing.

Here's a video showing controlled reduction and oxidation in two-terminal devices (containing multilayer graphene oxide films):

Researchers from the Rice University found a new way to create single layers of graphene by removing them from Graphene stacks, and they explain this in video:

We just found a couple of great short vidoes explaining about carbon and Graphene. The videos are presented by Dr. Jonathan Hare (who also wrote them) - who runs the creative science center in Sussex, UK. The first video is an introduction to Graphene: what is it, why is it important and how we can make our own Graphene sheets:

Osaka's university has a Spintronics research group that is working towards MRAM and STT-RAM using several materials including Graphene. Here's a nice intro video about the group:
