When particles in volcanic ash cloud rub together, some pick up positive charge and others negative – now physicists have ...

Learn more about the nearly invisible layer of carbon that may control how dust grains become electrically charged and how that discovery could help future missions to the moon and Mars.

When microscopic particles of sand, ash, or dust collide in the air, they often exchange a tiny electrical charge. This tiny ...

It’s a fundamental principle of physics that particles with opposite charges attract each other, while those with the same charge repel. But now, scientists at the University of Oxford have found that ...
