Nanoscale 'rainbows' could lead to improved solar cells and TV screens

New research at King's College London may lead to improved solar cells and LED-displays. Researchers from the Biophysics and Nanotechnology Group at King's, led by Professor Anatoly Zayats in the Department of Physics have demonstrated in detail how to separate colours and create 'rainbows' using nanoscale structures on a metal surface.

Major nanotechnology advance in using sunlight to produce steam without boiling water

Scientists today are describing a revolutionary new way to use sunlight to produce steam and other vapors without heating an entire container of fluid to the boiling point. The advance has potential applications, especially in the poverty-stricken areas of the developing world, that include inexpensive, compact devices for purification of drinking water, sterilization of medical instruments and sanitizing sewage.

Creating a coating of water-repellent microscopic particles to keep ice off airplanes

To help planes fly safely through cold, wet, and icy conditions, a team of Japanese scientists has developed a new super water-repellent surface that can prevent ice from forming in these harsh atmospheric conditions. Unlike current inflight anti-icing techniques, the researchers envision applying this new anti-icing method to an entire aircraft like a coat of paint.
