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.
