Innovation — Self-Cleaning

Nano-Engineered Window Is Self-Cleaning and Sustainable University College London (UCL) researchers have announced that a combination of thermochromatic coating and nano-scale engineering have created an innovative new window design could reduce cleaning costs and even heating bills by up to 40%. The surface of the prototype contains cone-shaped nanostructures that trap air and only allow a miniscule amount of water to contact the glass. In essence, rain will turn into balls upon striking the glass and roll off, removing dirt at the same time. With normal window glass, raindrops linger and roll down, leaving residue. According to the lead UCL researcher, this self-cleaning...
