A global organization needs innovative technologies that will decrease the surface friction between steel surfaces. Thin, 0.2-mm steel components must come into shear contact with each other, resulting in slip, wear, and heat. The components are lubricated to reduce friction. Any proposed solution must have some...

By minimizing the distance between the rotating vanes of a turbine and the static case structure housing the rotating blades, a client seeks to improve the efficiency of jet engines. Eliminating system leakage is essential to providing the most amount of energy for the lowest cost. The compressor fans of a turbine...

A technology recharges batteries in up to one-tenth the time of conventional methods. The device creates conditions within the battery that allow power to be input as fast as the cell can accept the charge. By creating a charging “ecosystem,” the optimum battery charging conditions are...

New polyester compositions feature desired electrical characteristics without unduly deteriorating the other valued melt viscosity, processing, and shaped article properties. The electrically conductive polyester has strong conductivity at low carbon black loading. The use of carbon black with...

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...

A treatment for stainless steel must impart high-release properties on par with non-stick coatings. The method should modify the surface of the stainless steel, but not reduce any of its existing properties, such as abrasion resistance, chemical resistance, or durability. The surface modification must resist sodium...
