Using a cold plasma jet to activate hydrogel, researchers have created a dressing with antibacterial and wound-healing properties. The technology could be used as an alternative to current treatments ...

Plasmas are often found in the center of stars – on Earth, the electrically charged gas mixtures are a rare occurrence, such as in lightning discharges or aurora borealis lights. However, you can ...

For about 20 years, Caltech Professor of Applied Physics Paul Bellan and his group have been creating magnetically accelerated jets of plasma, an electrically conducting gas composed of ions and ...
