A simple electrical method shows how protein nanowires carry both electrons and ions, offering a clearer way to design soft, ...

People use 'electricity' casually in their daily lives, but if you think about it, you don't know how electricity flows. Electronic circuit engineer Lucamtukh explains the question, 'What is ...

Scientists built a nano switch that controls excitons, chargeless quantum quasiparticles, at room temperature.

An electric current is a flow of charged particles. A source of energy, such as a cell or battery, is required to make the free electrons move in one direction. Electrons are negatively charged ...

A new nanostructure acts like a wire and switch that can, for the first time, control and direct the flow of quantum ...

Artist’s impression of the quantum spin Hall effect in a graphene-based spintronic device, integrated in a chip. The blue and red spheres are spin-up and spin-down electrons traveling along the edge ...
