Silica nanoparticles create fog-free mirrors and windows

Foggy windows and lenses are a nuisance, and in the case of automobile windows, can pose a driving hazard. Now, a group of scientists at MIT may have found a permanent solution to the problem. The team has developed a unique polymer coating — made of silica nanoparticles — that they say can create surfaces that never fog. The transparent coating can be applied to eyeglasses, camera lenses, ski goggles … even bathroom mirrors, they say. more . . .
