A recently developed ultrathin, gold-based transparent coating that is able to convert sunlight into heat is being proposed as a solution to prevent fogging in glass surfaces such as those in eyewear or windshields. The soon-to-be patented coating has been created by researchers at ETH Zurich employing methods that are used extensively in manufacturing such as vapour deposition under vacuum in a clean room to deposit minuscule amounts of gold onto the surface being treated. The coating is made up of a single gold nanolayer and is significantly thin, which makes it transparent as well as pliable. Further, it absorbs ... (full story)
