NANO CRYSTAL COATING Researchers have unveiled a semiconductor nano crystal coating material capable of controlling heat from the sun while remaining transparent. This heat passes through the film without affecting its visible transmittance, which could add a critical energy-saving dimension to “smart window” coatings.
