Tiny nanoparticles improve charge transport

Three-dimensional topological insulators are materials that can conduct electric current without resistance—but only on their surface. However, this effect is difficult to measure. This is because these materials usually ...

Creating a non-radiating source of electromagnetism

An international team of researchers has developed a way to create non-radiating sources of electromagnetism. In their paper published in the journal Physical Review Letters, the group describes their technique and how well ...

Flexible, wearable X-ray detector doesn't require heavy metals

X-ray imaging is a fast and painless way for doctors to see inside a person. But radiation detectors, which go under the body part being imaged, are rigid panels that contain harmful heavy metals, such as lead and cadmium. ...

Electric current

Electric current is the rate of flow of electric charge. The electric charge that flows is carried by, for example, mobile electrons in a conductor, ions in an electrolyte or both in a plasma.

The SI unit of electric current intensity is the ampere. Electric current is measured using an ammeter.
