Ice skating on water, even when it is really cold

The outermost layer of ice behaves like liquid water, even at a temperature of –30°C. Physicists at AMOLF have irrefutably demonstrated this using a modern surface-sensitive measuring technique. At lower temperatures, ...

Quantum optical cooling of nanoparticles

When a particle is completely isolated from its environment, the laws of quantum physics start to play a crucial role. One important requirement to see quantum effects is to remove all thermal energy from the particle motion, ...

Breakthrough in the search for graphene-based electronics

For 15 years, scientists have tried to exploit the "miracle material" graphene to produce nanoscale electronics. On paper, graphene should be great for just that: it is ultra-thin—only one atom thick and therefore two-dimensional, ...
