Scientists at Stanford University have designed a new paint that could help reduce our growing reliance on air conditioners and heaters.

2021年4月16日 · A new formula for white paint has given us the whitest white yet. It reflects a jaw-dropping 98.1 percent of all light that hits it, remaining significantly cooler than the ambient temperature, even when sitting in full sunlight.

2019年7月26日 · These can reduce surface temperatures by more than 10°C, compared to conventional paint. High performance solar glazing on windows also help, with coatings that are "spectrally selective", which means they keep the sun's heat outside but let daylight in.

2019年5月22日 · By insulating the drink inside the can from the metal can itself, the lining prevents acids and other chemicals in the beverage from corroding the aluminium – while at the same time preventing the aluminium from interacting with the liquid and affecting its flavour.

2019年12月18日 · "But for samarium nickel oxide, resistance changes in an unconventional manner from an insulating to a conducting state, which keeps its thermal light emission properties nearly the same for a certain temperature range."

2017年11月21日 · Space dandruff, which are things that have shed off space vehicles during flight, like ice flakes, paint chips, or fragments of insulation. They're different to space junk, because they don't pose a real threat to spacecraft, Oberg explains on his site .

2020年9月25日 · That hole seemed to indicate a manufacturing defect - it appeared that someone on Earth had attempted to plug the hole with paint, but that paint broke off after the Soyuz reached the space station.

With many plastic products, including foam in padding, casings for appliances, and wire insulation containing the products, microplastics from their breakdown are becoming a greater cause for concern.

2020年9月30日 · They spent nearly eight hours hacking at the insulation with a knife to find and document it. After that, the crew patched up the hole with an epoxy sealant. Roscosmos has since stayed quiet about the incident.

2019年7月8日 · These mosses can paint a lifeless landscape green almost overnight, paving the way for other organisms to arrive and establish. While the elderly mosses discovered by La Farge and Convey are remarkable, the clique of ice age survivors extends well …
