The performance of an object that has been dependent upon whether the object is composed of a conductive or a nonconductive material. Conductors are materials that allow electrons to flow freely from ...

Scientists have created a process to make patterns in atom-thick layers that combine a conductor -- graphene -- and an insulator -- hexagonal boron nitride. The process may lead to new possibilities ...

Recent progress in optics, atomic physics and material science has paved the way to study quantum effects in ultracold atomic alkali gases confined to non-trivial geometries. Multiply connected traps ...

An atom is the smallest unit of an element that retains its chemical properties. It is made of protons, neutrons, and electrons. (Image: M ...

Why do we get shocked when we come in contact with electricity? asks reader Sangpal Meshram. Don't touch an electrical outlet with wet hands. Keep hair dryers away from sinks and bathtubs. And never, ...
