Although there are highly sensitive methods for pathogen detection in donor blood, the risk of infection via transfusion remains. A customer seeks methods to inactivate all known and unknown blood-borne pathogens in blood products, especially where those technologies can be used for whole blood or red blood cells....

A non-destructive test mechanism is needed to detect fracture toughness, hardness, and microstructure properties of 1/8" steel weld zones. The device must measure the characteristics of flash upset welding of steel. In addition, the standalone technology should not function in a continuous, in-line...

High temperatures have been used to dissociate water, but in many cases, the oxygen and hydrogen recombine when temperatures drop. A new device magnetically separates hydrogen from oxygen at elevated temperatures. Steam enters a reaction chamber, heats to over 150 °C in a focused solar beam, and...

Using a piezo-actuated valve and an integral, closed-loop pressure control circuit, a modular controller maintains the pressure of non-corrosive to mildly corrosive gases. The Active Pressure Controller (APC) consumes minimal power (

Photonic crystals have received an increasing amount of interest for use as light extractors in light-emitting diodes (LEDs), but their implementation on the surface of LEDs has thus far produced little improvement in extraction efficiency.

Relaxed silicon-germanium (SiGe) has become an important material in the fabrication of high-quality films for various applications. Strain-relaxed SiGe buffers have been produced by at least three known methods. However, these techniques present several disadvantages, such as long growth times, thick...

The 2011 Create the Future Design Contest — sponsored by COMSOL, Inc., PTC, and Tech Briefs Media Group (publishers of NASA Tech Briefs) — recognized innovation in product design in seven categories: Electronics (new this year), Consumer Products, Machinery & Equipment, Medical, Safety & Security,...

NASA has partnered with Space Adventures to support the YouTube Space Lab competition that invites students to envision and design their own experiment with the ultimate prize -- flying it on the International Space Station. The contest opened on October 11, and will continue to accept submissions in the...
