New Toxicology Fears From Graphene Nanoplatelets

479164155_414a944275

As reported here several weeks ago the graphene investment story is not all plain sailing. Toxicology concerns have been expressed for some time and unfounded comparisons between the nanomaterial and asbestos have been suggested. Fears that graphene could potentially cause respiratory problems in people involved in the manufacturing process have been raised along with fears that the nano-sized particles could affect the food chain.

Investors in business are always concerned about the potential return on investment and this remains as true within the graphene marketplace as it does within any other commercial venture. Before investing individuals and organisations want to know the level of risk and the potential rewards before they commit their money to an enterprise. In the graphene industry there are many unknowns that raise the level of risk but there is one key consideration that could unlock a lifetime of profit.

Graphene Nanoradio, Tune in Turn On Drop Out.

nanoradio

Graphene radio is the latest innovation to have emerged from the work of researchers from Universities in Romania, France and Greece .

Following on from the work of a team at Columbia University who announced to the world the first graphene radio in Dec 2011, the researchers from Europe have now presented evidence of RF demodulation by a single sheet of graphene embedded in a coplanar structure that suggests graphene responds well in the frequencies currently used in industrial, medical and scientific devices. Tested in a frequency range of 100Mhz to 25Ghz the graphene monolayer exhibited a response that suggests it could also be used for short range wireless communication such as Bluetooth.

Graphene Transistor Hurdle Cleared

VerticalTransistorM 2012

A major hurdle in the race to manufacture a graphene computer chip has been cleared by scientists at the University of Manchester. The team of researchers lead by the Nobel Laureates Andre Geim and Konstantin Novoselov, have happily announced that the problem of graphene’s near super-conductivity has now been solved. The research finding is set to reignite the race for a graphene transistor and the race is now on to see which team will be the first to make the breakthrough device that will make graphene the new silicon.
