Slick Invention Can Un-Stick Your Ketchup, Toothpaste
LiquiGlide, SLIPS Technologies take advantage of 'liquid-impregnated surfaces'

(Newser) – Hate when you can't get the last of the toothpaste from the tube? Or when your plane is delayed so it can be de-iced? Those days may soon be over thanks to what are essentially surfaces coated with liquid. Researchers at both Harvard and MIT have taken advantage of the technology separately; in both cases, a liquid surface is attached to a solid surface lining by chemical and physical reactions. Basically, "you create a liquid on top of a solid—a nice slippery liquid interface that protects your solid," a Harvard researcher says. However, the Harvard-linked SLIPS Technologies serves to keep liquid in place, while LiquiGlide, run by a former MIT student, produces a slippery liquid surface, reports Inside Science.

As liquid can flow in narrow spaces unaffected by gravity, SLIPS manipulates surfaces to immobilize liquid. "We're really nucleating a new and original type of materials science," a researcher says. Meanwhile, LiquiGlide's CEO says its focus is similar to "putting oil and then an egg in a frying pan." The Boston Globe previously reported the company's custom coatings from edible products could have a variety of uses: Ketchup bottles could serve out the red stuff with a simple tilt, and clogs in oil pipelines could become nonexistent. In fact, by preventing water droplets from collecting on steam turbines, "you can slow down global warming," a researcher says. The company expects the first products to roll out in 2015.
