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...

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...

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...

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...
