NASA's Langley Research Center has developed a new low-temperature method of SiGe/sapphire growth that produces the same single-crystal films with much less thermal loading effort to the substrate. This eliminates the time-consuming and costly high heating, long thermal soak times, and interfacial Si layer....

In today’s lead INSIDER story, Professor Jordan Raney said that the most interesting feature of his embodied-logic system is its ability to monitor an environment for a very long period of time, without needing a continued input of energy.

In today’s lead story, Stacy Janes showed optimism regarding the security of connected cars.

Lithium-ion batteries are an integral part of energy storage systems used in NASA's Exploration program, as well as many modern terrestrial industries. NASA Johnson wanted a better way to measure total and fractional heat response of specific types of Li-ion cells when driven into a thermal runaway condition.

Batteries, such as lithium-ion, sold for consumer use in portable electronic devices and other applications such as electrical cars, occasionally fail in the field over time. These cells have typically passed a wide variety of safety tests such as those required by governmental...

A material, inspired by nature, can regulate its own temperature and could be used to treat burns and help space capsules withstand atmospheric forces. The research used a network of multiple microchannels with active flowing fluids (fluidics) as a method and proof-of-concept to...
