SETI proposes to develop GaN and Si based multicolor FIR/THz cameras with detector elements and readout, signal processing electronics integrated on a single chip. The active detector elements will be submicron gated channels with 2 dimensional electron gas (2DEG). The devices with gated 2DEG (commonly known as field-effect transistors) respond to the incoming FIR radiation due to the rectificat ...

Adsorption refrigeration using ammoniated complex compounds as the absorbent media can be used for miniature portable blast freezers. This is possible because the technology allows low evaporator temperatures without staging, is scalable to small sizes, and has high reliability because the only moving parts are check valves. Compared to vapor compression or other sorption refrigeration systems, th ...

This proposal outlines the design and development of a uniflow two stroke Aero-Diesel engine core in response to the NASA SBIR solicitation for a general aviation aircraft propulsion system. The proposed engine will offer increased power density, simplified operation, reduced emissions, noise, and vibration, while enhancing reliability and safety when compared to currently available general aviati ...
