79252 As environmental regulations become increasingly stringent, there is mounting pressure on automobile manufacturers to substantially lower unburnt hydrocarbon emissions. This will require monitoring the hydrocarbon content in the exhaust with more accuracy than currently possible using the two oxygen sensor system. This requirement is especially important during start-up conditions, which a ...

76066S Ceramic membranes with ion-specific conducting properties can provide gases with purity unmatched by other gas separation methods. However, in order to realize the full potential of these membrane devices, high temperature seal materials are required to isolate the ultrahigh purity product gas from the inlet gas mixture. This project will develop a composite seal material that combines t ...

High energy density battery will be developed by combining metallic sodium anode with an air cathode. The proposed sodium-air battery is expected to dominate the performance of lithium-air battery. This battery technology is based on sodium conducting solid-electrolyte developed at Ceramatec Inc. The sodium conducting solid-electrolyte has conductivity in the range of 10-2 S/cm at ambient tempera ...

Cermet, Inc in collaboration with Georgia Institute of Technology proposes to develop spin Light Emitting Diode (LED) in a 24 month Phase II program. The spin LED is a simple yet powerful spintronic device that produces circularly polarized light and is a potent tool to quantify the spin injection efficiency and spin polarization efficiency.

The goal of this effort is to grow n and p ZnO thin films by MOCVD on ZnO substrates. The primary objective of this phase I effort will be to grow p-n homojucntion and characterize the LED structure. Bandgap of ZnO will be engineered and heterojunction quantum wells will be grown. The grown device structures will be characterized for structure and quality by X-ray, PL and electron microscopy, The ...

The goal of this program is to develop ZnO based light emitters fabricated on high quality ZnO bulk substrates. The work will focus on enhance doping of the active layers, target alloy concentrations and prototype emitter fabrication.

Stockpiles of weapons with composite rocket motors have been expensive to acquire. In the fortunate occurrence that these weapons are not used, they are too expensive to discard based upon simple expiration dates. However, use of these weapons can be dangerous if their integrity is compromised due to aging and deterioration. CogniTech proposes to build a software suite containing a graphical ...

Crossfield proposes to develop a hybrid direct write technique for developing conformal circuits and semiconductors. Crossfield, together with Honeywell and the Massachusetts Institute of Technology (MIT) intend to demonstrate a conformal circuit technique that enables the metal elements of the circuit (such as power and signal traces or antennas) and supporting semiconductors such as bias circui ...

Crossfield proposes a high dynamic range, ultra-wideband, receiver-digitizer that will enable implementation of a compact UWB target identification system for the detection and location of targets and weapons concealed behind walls or foliage or hidden on a person. The design features an ultra-wide bandwidth, high dynamic range sampler developed by Picosecond Pulse Labs, followed by a track-and-ho ...

Crossfield Technology proposes an innovative direct conversion receiver and digital signal processor system that provides ultra wideband frequency coverage at ultra high frequency resolution. Key features of Crossfield's ultra wide band receiver and signal processor design include: Ultra wide band direct conversion (zero-IF or near-zero-IF) using state-of-the-art SiGe analog-to-digital convert ...
