Better-glass breakthrough achieved using just sound and salt | The brand-new method may lead to glass made without the use of harsh chemicals for self-cleaning windshields, germ-busting surfaces, or maybe even better beer.
Using ultrasonic waves and a salt bath, a research team has altered the surface of glass. The brand-new method may lead to glass made without the use of harsh chemicals for self-cleaning windshields, germ-busting surfaces, or maybe even better beer.
To create the material, a team of scientists at Australia's Curtin University (CU) submerged ordinary glass in a nontoxic bath of organic compounds known as diazonium salts. "This triggers a reaction that forms a stable, organic layer to the glass, making it either permanently water-repellent or positively charged, depending on the type of diazonium salt used. Unlike conventional coatings that wear off over time, our method creates a chemical bond at the molecular level, making it far more durable and environmentally friendly."
