LANZHOU, Feb. 27 (Xinhua) -- Researchers have developed a new type of ceramic aerogel which can be used in thermal insulation.

The new ceramic aerogel, developed by Chinese and American researchers, has strong mechanical and thermal stability, as well as excellent performance in transformation and toughness.

Aerogels, made of ceramics, carbon, or metal oxide, have a robust structure, said Zhang Qiangqiang, a professor at Lanzhou University in northwest China's Gansu Province.

Previous ceramic aerogels were plagued by poor mechanical stability and degradation under thermal shock. The new material is considered an ideal thermal insulation material due to its low density, low thermal conductivity, and fire resistance.

The new aerogel maintained great mechanical stability throughout hundreds of severe thermal changes between minus 198 degrees Celsius and 900 degrees Celsius. It had less than one percent degradation under thermal shock.

Lightweight aerogels are promising replacements for thermal insulation. Ceramic aerogels are ideal for thermal superinsulation under extreme conditions, such as those encountered by spacecraft.

To seamlessly integrate electronics with the natural world, materials are needed that are both stretchable and degradable -- for example, flexible medical devices that conform to the surfaces of internal organs, but that dissolve and disappear when no longer needed. However, introducing these properties to electronics has been challenging. Now, researchers reporting in ACS Central Science...

Imagine a device that can sit outside under blazing sunlight on a clear day, and without using any power cool things down by more than 23 degrees Fahrenheit (13 degrees Celsius). It almost sounds like magic, but a new system designed by researchers at MIT and in Chile can do exactly that.The device, which has no moving parts, works by a process called radiative cooling. It blocks incoming sunlight...
