Graphene is a thoroughbred that has to be tamed
Electrons in graphene behave like light particles; they have no mass and can penetrate everything: very useful if you dream about nano-electronics. But you do have to channel them. Carlo Beenakker will be researching how. He has been awarded an ERC Advanced Grant of 1.5 million euro to carry out this…

Perfect for designing new molecules
Even a small quantum computer should be able to simulate exactly the properties and behaviour of new molecules. This would take chemistry to an entirely new level. Better solar panels, more powerful batteries, saving lots of energy in the chemical industry: the applications have the potential to transform…

Modeling energy conversion dynamics at interfaces
Chemical reactions go hand-in-hand with an energy exchange with the environment in which they take place. Surfaces offer a variety of energy dissipation channels, constituted by the nuclear and electronic degrees of freedom of the atoms at the interface. Aiming at an improved future harvesting of energy,…
