In recent years there’s been a lot of fuss about graphene’s marvel-like abilities and how it could make our world much more efficient, but until recently, scientists haven’t actually been able to wrap their heads around a way to produce the material on a commercial scale. A recent University of Cambridge spin-out company, Paragraf, is claiming to have started producing graphene – a sheet of carbon just one atomic layer thick – at up to eight inches in diameter, large enough for commercial electronic devices. The applications for graphene are nearly endless. Despite its remarkable small size, it’s the strongest material known to exist: it’s harder than diamond, 200 times stronger than steel and 10 times better at conducting heat than copper, the conductor used in most electronics. Paragraf claims its first graphene-based products will be ready within the next few months.
