Researchers made steel stronger, safer and more durable by coating its surface with nanoporous tungsten oxide. The new surface coating is claimed to be the most durable antifouling and anticorrosive material to date, capable of repelling any kind of liquid even after sustaining intense structural abuse. The material could be used in non-fouling medical tools, nozzles for 3D printing and, potentially, larger-scale applications for buildings and marine vessels.
