Electric Potential Difference: Students learn to describe changes in the potential and kinetic energy of a point charge as it moves in an electrical field. Potential difference is introduced in terms ...

Dutch Researcher Katja Heister investigated how electrical potential differences in clay layers influence the transport of salt and water through these. The outcomes of her research have important ...

Shini explores electric current, voltaic cells, and how we get electric charge. Electric current works like a river... kinda... Instead of flowing based on elevation ...

Zeta potential is a key indicator of the stability of colloidal dispersions and nanoparticle suspensions. It measures the electrical potential difference between the bulk of the liquid and the ...

There's waterproof and then there's the surface developed by engineers at the University of California San Diego. They've developed a surface so hydrophobic that it can actually be used to generate ...

Engineers have developed a super-hydrophobic surface that can be used to generate electrical voltage. When salt water flows over this specially patterned surface, it can produce at least 50 millivolts ...
