SEM micrograph of a strongly crumpled graphene sheet on a Si wafer.
Congratulations to Andre Geim (University of Manchester, UK) and Konstantin Novoselov (University of Manchester, UK) for winning the Nobel Prize in Physics 2010!
And if you have a subscription, check out this cool paper that came out last week, Theoretical investigation of Möbius strips formed from graphene.
Super black is a surface treatment developed at the UK’s National Physical Laboratory. It reflects much less light than the darkest conventional matte black paints currently available. When light hits the surface at right angles approximately 99.6% is absorbed and only 0.4% is reflected: by contrast black paint reflects about 2.5% of the incident light. However, super-black is even more effective at absorbing light that hits it at an angle; if the light source is at an angle of 45°, super-black reflects 1/25 as much as black paint. The technique is based upon chemically etching a nickel-phosphorus alloy.
