Lasers have yet another use. Scientists are using them to transform metals into extremely water-repellent materials without the need for temporary coatings. This could be huge for airplanes, anti-rust materials and other applications.
Water-repellent, or super-hydrophobic, materials are useful for several different applications. They can be used for rust prevention, anti-icing or even sanitation uses. Yet most hydrophobic materials currently rely on chemical coatings, which can wear off and affect the surrounding environment.
