Researchers have found a way to control the charge of nanoparticles on a two-fluid interface to create a more stable system in which its charge can also be switched and controlled. The ability to change the charge of nanoparticles on a two-fluid interface would result in a surface that could acclimate itself to fit many diverse applications, such as a more durable firefighting operation and even controlled release in certain medications.

A new type of ultraviolet light that is safe for people destroyed more than 98 percent of airborne microbes in a room within five minutes, a study found.
