Electrostatic loudspeakers work by the attraction and repulsion of a thin conductive film in an electric field rather than the magnetic attraction and repulsion you’ll find in a moving-coil ...

A study in Engineering reveals a new adsorbent made by combining cationic surfactants with montmorillonite. This adsorbent ...

Indeed, the foam effectively grabs plastic particles through a combination of electrostatic attraction, physical entrapment, and other intramolecular forces. It both attracts microplastics via ...

This energy overcomes the strong electrostatic forces of attraction which act in all directions between the oppositely charged ions: The strength of the ionic bonds depends on the charge on the ions.

The system features an electrostatic ionizer that reduces attraction between dust particles and their accumulation on modules, improving their energy yield. Researchers from the University of ...
