SiGe enables faster carrier mobility and less energy loss than single crystal silicone, thus increasing processing capacity and reduced size, as well as power requirements for a unit of the same size. SiGe provides new product functionality that increases its effectiveness by 33% and extends the operational life to 80 years in solar cell applications.

NASA's Langley Research Center invented a new method that allows the fabrication of metal/composite hybrid laminates, also known as fiber-metal laminates, by a one-step processing process. Currently FMLs are produced by a compression process that includes metallic layers sandwiched between layers of glass or graphite prepreg.

Scientists at NASA's Glenn Research Center have developed and patented improved ohmic contacts, as well as a manufacturing technique for them, that can be used to expedite the fabrication of silicon carbide sensors and electronics that operate in high-temperature, harsh environments. Without compromise, security, and contact robustness, Glenn's technology results in universal and simultaneous ohmic contacts for both n- and p-type SiC semiconductors without compromising safety and connectivity.

The NASA Ames Research Center's built-in temperature sensing device for microheaters has been developed. NASA has invented a novel resistor-based microheater that depends on a Joule heating system. The resistance is dependent on the body temperature, which means that the microheater has an inherent sensing system that eliminates the need for embedded sensors.

In a portable film format, the dual solar energy harvesting film provides maximum energy production. Solar devices can be optimized for higher thermoelectric or photovoltaic conversion for maximum effectiveness, but the design team also encourages a focus on weight to energy conversion ratios for improved conversion. The benefits of internal structure variation that allows it to absorb more energy from a particular solar energy source are shown.

The Marshall Space Flight Center researchers at NASA's Marshall Space Flight Center have developed a new, more robust aluminum alloy that is ideal for casting aluminum alloys with powder or paint-baked thermal coatings. The NASA-427 alloy exhibits increased tensile strength and increased ductility, resulting in substantial improvement in impact toughness with improved mechanical properties.

NASA has devised a novel strategy for extracting sugars and sugar acids enriched with one of the two enantiomers of individual compounds. Other amino acids, for example, can also be used. Using biological sources is a key to high enantiomer excesses from simple and inexpensive precursors and hardware components that are not used or expensive for biological sources.
