Researchers develop nano-thin gold coating to prevent glass from fogging up

Ideal for eyeglasses and windshields
In a nutshell: Researchers at ETH Zurich have spent the last few years perfecting a coating capable of passively preventing fogging on glass surfaces. Their latest iteration consists of extremely thin clusters of gold situated between ultrathin layers of titanium oxide on the top and bottom. The resulting coating is able to absorb a portion of infrared radiation from the Sun, which heats up the surface by as much as eight degrees Celsius and prevents condensation from forming.
