Dresden scientists have developed a self-cleaning metallic surface. A project team of Technische Universität Dresden and the Fraunhofer Institute for Material and Beam Technology IWS structured an aluminium plate with a laser process in such a way that water droplets no longer adhere and dirt particles can be removed from the surface—completely without chemical cleaning agents or additional effort. The scientific evidence of the self-cleaning effect has been published in the journal Applied Surface Science.
