Relaxed SiGe Films By Surfactant Mediation

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...

Tech Needs
Stainless Steel Surface Treatment

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...

A More Efficient Turbo Propulsion System

Using higher exhaust exit temperatures, a company needs to improve the efficiency of a turbo propulsion system. Methods should reduce component weight primarily in the core compressor component (or secondarily anywhere in the flow path) through new compressor geometries or aerodynamic improvements. Lower...

Piezo-Electric Actuator Provides Motion Control Alternative

An alternative piezo-electric ceramic actuator simultaneously provides greater force and deflection, while producing no appreciable magnetic field or heat. The RLP domed piezo, a PZT disk laminated between two metal layers under heat and pressure, increases deflection 1,000-fold from an...

Lateral-Flow Device Produces Quantitative Diagnostics

A patent suite enables quantitative diagnostics from inexpensive and disposable lateral-flow test strip technology. Multiple, simultaneous analyses can be conducted on the same strip. The method reduces the hook effect, a dangerous false negative, without requiring long wait times; larger,...

Tech Needs
Non-Smoke, Non-Halogenated Fire Retardants

A company needs non-halogenated polymeric mix additives that provide non-smoke fire retardance for wiring jackets and cables. The additive must have low enough loadings so that product performance and flexibility are maintained. Wires and cables must meet a variety of requirements, some imposed by...

Materials That Build Viscosity Upon Dilution with Water

A new material needs to maintain a low viscosity when concentrated or anhydrous, and then build viscosity when diluted with water. It should have an approximate concentrated viscosity of less than 500 cps, and a diluted viscosity greater than 1,000 cps when diluted to 50% or more with...

New Methods to Sterilize Food Products

Traditionally, heat treatments are used to sterilize food products, through either ultra-high-temperature processing or retorting. These treatments negatively affect the color, taste, and nutritional content of the food products, especially for “non-cooked” products such as gazpacho, cheese-based or...

NASA Tech Needs

NASA needs a sensor system to characterize damage from Micro-meteoroid and Orbital Debris (MMOD), corrosion, or to perform configuration verification when there...
