(University of Illinois College of Engineering) Gilding is the process of coating intricate artifacts with precious metals. Ancient Egyptians and Chinese coated their sculptures with thin metal films using gilding -- and these golden sculptures have resisted corrosion, wear, and environmental degradation for thousands of years. In a new study, University of Illinois researcher Sameh Tawfick, inspired by this ancient process, has added a single layer of carbon atoms, known as graphene, on top of metal leaves -- doubling the protective quality of gilding against wear and tear.
