Incredibly thin, flexible, strong and electrically conductive, graphene has the potential to revolutionize electronics and materials. One of the main hurdles though is that it’s tricky to manufacture on large scales. Now researchers at the University of Rochester have recruited bacteria to make the stuff, which is cheaper and faster than current methods and doesn’t require harsh chemicals.
Corrosion in metals can lead to the structural fatigue or failure of bridges, pipelines, and plane fuselages. Anti-corrosion coatings help prevent this, but they become ineffective when pierced, cracked, or scratched away. Researchers at Northwestern University have now developed a self-healing coating that can patch up its imperfections in a matter of seconds.
Forget steel, forget diamond and even forget everyone’s favorite wonder material graphene – “nuclear pasta” may be the strongest material in the universe. This strange substance is formed in the intense pressures inside neutron stars, and researchers have now run computer simulations to test just how strong it is.
