'Artificial atom' created in graphene

In a tiny quantum prison, electrons behave quite differently as compared to their counterparts in free space. They can only occupy discrete energy levels, much like the electrons in an atom - for this reason, such electron ...

New material could advance superconductivity

Scientists have looked for different ways to force hydrogen into a metallic state for decades. A metallic state of hydrogen is a holy grail for materials science because it could be used for superconductors, materials that ...

Lonely atoms, happily reunited

The remarkable behaviour of platinum atoms on magnetite surfaces could lead to better catalysts. Scientists at TU Wien (Vienna) can now explain how platinum atoms can form pairs with the help of carbon monoxide.
