SUPERSLIPPERY SIDE UP

These two steel balls sit in a pool of octane, a component of petroleum, that has been dyed yellow. Though the ball on the left has picked up streaks of the oily liquid, the ball on the right has repelled the octane thanks to a self-healing, superslippery coating called X-SLIPS. Researchers developed this coating, which repels both water and oil, based on the slippery interiors of Nepenthes pitcher plants and the wax layer on plant leaves. To make the coating, the team applied a 2.5- µm-thick layer of fluorinated silane to the sanded surface of the ball. A spritz of DuPont’s Krytox lubricant, a perfluorinated oil similar to Teflon, adheres tightly to the silane to create a surface that fends off water and oil. After damaging the coating with blasts of oxygen plasma or abuse with 40-grit sandpaper, the researchers could restore it by simply heating it, causing the remaining silane to redistribute across the surface and re-adhere. The coating could be useful on ships or in condiment packaging.

compare me when people blab about “”beautiful hardwood floors”” to me when people paint over literally any piece of wooden furniture to me when people paint over wood laminate furniture especially to me when the word “teak” falls out of anybody’s mouth

If Vancouver deserves credit for anything (aside from the ecological initiatives and bike routes) it is perhaps the need decorate the city’s many varied surfaces.

this is my favorite in painting shortcuts archaeology. this is the pantry, which is actually an addition from maybe fifteen years ago, so this is almost the only wall in the house that isn’t from the twenties. that white is unpainted drywall! they put the modular shelving up before they treated or painted the wall at all, then just painted around the brackets! they were like glued on by paint, too, guess it made them stronger!!
