Graphene: A Material That Multiplies the Power of Light

Bottles, packaging, furniture, car parts... all made of plastic. Today we find it difficult to imagine our lives without this key material that revolutionized technology over the last century. There is wide-spread optimism in the scientific community that graphene will provide similar paradigm shifting advances in the decades to come. Mobile phones that fold, transparent and flexible solar panels, extra thin computers... the list of potential applications is endless.

The most recent discovery published in Nature Physics and made by researchers at the Institute of Photonic Science (ICFO), in collaboration with Massachusetts Institute of Technology, USA, Max Planck Institute for Polymer Research, Germany, and Graphenea S.L. Donostia-San Sebastian, Spain, demonstrate that graphene is able to convert a single photon that it absorbs into multiple electrons that could drive electric current (excited electrons) -- a very promising discovery that makes graphene an important alternative material for light detection and harvesting technologies, now based on conventional semiconductors like silicon.

"In most materials, one absorbed photon generates one electron, but in the case of graphene, we have seen that one absorbed photon is able to produce many excited electrons, and therefore generate larger electrical signals" explains Frank Koppens, group leader at ICFO. This feature makes graphene an ideal building block for any device that relies on converting light into electricity. In particular, it enables efficient light detectors and potentially also solar cells that can harvest light energy from the full solar spectrum with lower loss.

I'm ready to dump my shares in Kryptonite for equal shares in Graphene. Where can shares of Graphene be purchaed?

I am with a micro-cap company called Lomiko Metals (TSX-V: LMR, OTC: LMRMF) which has recently signed a Strategic Alliance Agreement with Graphene Labs of New York. I was recently in Washington at the TechConnect Conference and one of the things that jumped out at me was how busy the Graphene Labs table was compared to many other graphene companies there.

I think graphene will definitely make an impact but there are many groups that are earnest but not capable or capable but not earnest. Buyers beware. We have all the right stuff in the ground (high carbon content graphite) and the right partner in Graphene Labs (who work with Stony Brook University in developing supercapacitors) yet it is difficult for us to find long term investors who see the coming graphene revolution and are able to find us. Graphene Labs owns www.graphene-supermarket.com which is one of the few places that sells graphene for laboratories online.  They have 5000 customers full of Fortune 500 companies, governments and agencies.

Our public company has the exclusive right to purchase an equity stake in Graphene Labs and we would welcome scrutiny from the right people.

We are asking people to dig deeper and take a look.
