Multi-Color Quantum Well-Based LEDs

A process to enhance the electron-hole wave functions overlap – resulting in high-efficiency quantum well light-emitting diodes (LEDs) emitting in the green and yellow wavelengths – has been developed. This proposed technique changes the polarity of the structure and diminishes the piezoelectric effect. It...

Friction Reduction of Steel Surfaces

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...

Structural Detection of Welded Steel Regions

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...

Magnetic Device Separates Hydrogen from Oxygen

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...
