Granular materials and fine powders are used across various industrial processes and applications. To optimize and control processing methods, these materials have to be characterized precisely.

After a year of trial and error, Liyang Chen had managed to whittle down a metallic wire into a microscopic strand half the width of an E.coli bacterium — just thin enough to allow a trickle of ...

Gaining control of the flow of electrical current through atomically thin materials is important to potential future applications in photovoltaics or computing. Physicists have discovered one way to ...

The film explains the concept of electrons and their role in electric circuits. It describes how electric current is the flow of electric charges, primarily electrons, which cannot be seen but can be ...

A weird phenomenon in which electricity flows like water was spotted in a nanowire made of "strange metal" — a bizarre metal phase that has stumped physicists for 40 years. When you purchase through ...

The effects of electric discharge are all around us. The simple act of electricity flowing from one point to another is responsible for so many phenomena in our lives here on Earth and beyond.

The team measured the electrical charge and contact areas created by water droplets spreading and contracting on a flat plate of Teflon – effectively simulating the movement of droplets over the ...

What is resistance? The most common definition of resistance is the opposition to current flow—more specifically the flow of electric charge in a material. The circuit element used to model this ...

For more than 50 years, the International Conference on Magnetism series has been inspiring researchers in the field. At the latest meeting in Karlsruhe, Germany, the control exerted by nanostructured ...

Could decades of magnetospheric theory have been looking at Earth’s electric heart the wrong way around? The answer, in new research, is yes and the implications ripple from satellite safety to ...
