Graphene is expected to behave like a quantum-critical, relativistic plasma known as "Dirac fluid" near charge neutrality in which massless electrons and holes rapidly collide. In a recent study now published in Science, ...
For his thesis, EPFL Ph.D. student Raphaël Lamotte studied rush-hour traffic congestion. He suggests implementing a system whereby commuters reserve time on a special traffic lane – like booking a seat on a flight – ...

(Phys.org)—Researchers have fabricated a smart skin that is self-powered by its frictional contact with the objects that it touches. When a honeybee crawls across the smart skin, the skin not only senses the insect, it ...
In the future, a wireless charging system will allow electric cars not only to charge their batteries, but also to feed energy back into the power grid, helping to stabilize it. The cost-effective charging system achieves ...

(Phys.org) —The ubiquitous van der Waals interaction – a consequence of quantum charge fluctuations – includes intermolecular forces such as attraction and repulsion between atoms, molecules and surfaces. The most long-range ...
Biophysics researchers at the University of Michigan have used short pulses of light to peer into the mechanics of photosynthesis and illuminate the role that molecule vibrations play in the energy conversion process that ...
