Breaking the Temperature Barrier in Aerospace Materials Testing

University of Illinois researchers have demonstrated a new method for testing microscopic aeronautical materials at ultra-high temperatures. The test combines two commonly used tools in a unique way. Using a transmission electron microscope and targeted laser heating, they were able to see and control where and how the material deformed at the highest temperature possible before the sample evaporated.

Wearable Device Camouflages Its Wearer Regardless of the Weather

Researchers at the University of California San Diego developed a wearable technology that can hide its wearer from heat-detecting sensors such as night vision goggles, even when the ambient temperature changes. It's a feat that current state of the art technology cannot match. The new technology can adapt to temperature changes in just a few minutes, while keeping the wearer comfortable.

Fuel-Efficient Engine for Cheaper, Lighter Spacecraft

Ending NASA’s Space Shuttle into orbit required more than 3.5 million pounds of fuel, which is about 15 times heavier than a blue whale. But a new type of engine — called a rotating detonation engine — promises to make rockets not only more fuel-efficient but also more lightweight and less complicated to construct. There’s just one problem: Right now, the engine is too unpredictable to be used in an actual rocket.

Understanding Condensation Leads to Better De-icing Materials

Water repellency is needed for surfaces to shed condensation buildup. New research by the University of Illinois and North Carolina State University shows that the necessity of water repellency is unclear and that the slipperiness between the droplets and solid surface appears to be more critical to the clearing of condensation.
