Graphene in the News Cycle

My Dad rang me last week to tell me about wonder material Graphene, after a story appeared in Cycling Weekly. Actually the reason my Dad rang me was mostly because my supervisor was appearing in his magazine.

Sir Harry Bhadeshia: Graphene won't deliver improved mechanical properties

Sir Harry Bhadeshia: Graphene won’t deliver improved mechanical properties

Prof Sir Harry Bhadeshia was contacted by cycling weekly after describing in a Materials World article how the mechanical strength comparison of Graphene against steel is absolute rubbish. That’s because of the strange claim that Graphene is 200 times stronger than steel. In fact a fairer comparison would show that the properties available at the nanoscale are 6.5 times stronger than steel, however those mechanical properties of Graphene just cannot be realised in principle at the scale of millimetres or above. The reason is that the properties rely on perfection, and only small structures can approach this perfection.
