“You cannot have freedom without a rule of law ... and if you don't have it, what you tend to get is corruption and that is death to freedom, it's death to truth, it's death to honour, it's death to democracy.”
Margaret Thatcher, 1 October 1996.

Graphene solar cells
Whilst still less than 10% efficient a team at The University of Florida has produced higher efficient graphene solar cells. The group was able to achieve an impressive 8.6 percent efficiency device by chemically doping, the graphene with trifluoromethanesulfonyl-amide. Their results are published in the online edition of Nano Letters.
