A new “mechanochemical” process allows the recycling of Teflon by grinding it with sodium metal at room temperature. This solvent-free reaction breaks down Teflon’s carbon-fluorine bonds, producing harmless carbon and sodium fluoride instead of toxic PFAS. The sodium fluoride can be reused in fluorine-based products, making this approach a breakthrough for sustainable plastic recycling and circular fluorine chemistry.

A team of scientists has created a microscopic engine made from a 5-micrometre glass bead suspended in an electric field. By applying oscillating voltages, the bead moves as if it’s in an environment of 13 million°C, even though it remains cool. The study reveals bizarre thermodynamic effects at tiny scales, offering clues to how natural molecular “machines” work inside living cells.
