Coating Prevents Fogging on Transparent Surfaces

Anyone who skis, wears glasses, uses a camera, or drives a car is familiar with the problem: Coming into a humid environment from the cold causes eyewear, camera lenses, or windshields to quickly fog up. Researchers have developed a new transparent material coating that greatly reduces this effect. A few nanometers thick, the durable coating is made of gold nanoparticles embedded in non-conductive titanium oxide.
