3D models of electrical streamers

Streamers may be great for decorating a child's party, but in dielectrics, they are the primary origin of electric breakdown. They can cause catastrophic...

Indiana Jones meets George Jetson

A team of researchers from Uppsala University in Sweden has designed a microplasma source capable of exciting matter in a controlled, efficient way. This...

Making wafers faster by making features smaller

Washington, D.C. (December 14, 2010) -- The manufacturing of semiconductor wafers used in all types of electronics involves etching small features onto a wafer with lasers, a process that is ultimately limited by the wavelength of the light itse...

Artificial black holes made with metamaterials

Washington, D.C. (November 16, 2010) -- While our direct knowledge of black holes in the universe is limited to what we can observe from thousands or millions of light years away, a team of Chinese physicists has proposed a simple way to design an a...

New way of detecting concealed radioactive material

Washington, D.C. (November 9, 2010) -- Researchers at the University of Maryland have proposed a scheme for detecting a concealed source of radioactive material without searching containers one by one. Detection of radioactive material concealed in ...
