We propose to develop a low SWaP, portable microwave Rb-87 cold atomic clock using pulsed coherent population trapping (CPT). The SWaP goal is to achieve a volume of

The primary goal of this proposed effort is to develop mid-wavelength infrared (MWIR) colloidal quantum dot (CQD)-based focal plane arrays (FPAs) to significantly reduce the cost of MWIR photon imagers. In order to realize this goal, it will first be nec

The overall goal of this Phase II project is to demonstrate the feasibility of the proposed OPTIMA technology through modeling, design optimization, and experimental demonstration of the accelerometer prototype. During the Phase II, we plan to continue th

A team at EP Purification has performed research for the development and commercialization of low-cost microchannel plasma reactor modules capable of efficiently producing ozone for water treatment and other environmental applications in a slim form factor and size. The conservation of water resources for human consumption is a growing national priority. Ozone is a unique purification agent as it ...

NEI Corporation proposes to develop a new and sustainable aqueous electrolyte-based lithium-ion (Li-ion) battery system that is capable of delivering high energy density, comparable to state-of-the-art Li-ion batteries. Almost all commercial Li-ion batteries use an organic electrolyte, which is flammable and has been a concern particularly in large format Li-ion batteries. In addition, there are t ...

Piezoelectric ceramics in sensors have achieved substantial market penetration. These parts are used widely for heat and climate control, hydrophones, flow sensors, medical and industrial sensing and accelerometers but they have been unsuccessful in gaining significant use in actuators. It generally is felt that material restrictions, precluding development of actuator-sized displacement strokes ...

This Phase I project will investigate using scrap tires to form a protective system for mitigating local scour around bridge piers. Local scour is the erosion of the riverbed around bridge piers, which is induced by the recirculating juncture flow at the intersection of the pier and the riverbed. Bridge failure caused by this phenomenon has long been an important issue with respect to both publi ...

Diamond Materials Incorporated (DMI) proposes to synthesize a new class of carbon-carbon composite, termed "Fullertubite". In conventional carbon-carbon ceramics, composite properties are controlled by the anisotropic properties of the carbon fibers. Fullertubite, synthesized from randomly oriented micron-sized carbon nanotubes, has the potential to overcome the anisotropic strength properties, ...

The Clean Air Act of 1990 has raised the concern over trace concentrations of metals in flue gas from electrical generation plants, municipal waste incinerators, and heavy industrial plants. Monitoring will be required to determine the environmental impact and offers an opportunity to empirically minimize it. In flue gas, metals are found in both the vapor state and condensed on fly ash. For sp ...

An ultra-lightweight, exceptionally small, combat hand-held diver sonar is proposed for shallow water search. The sonar provides high resolution synthetic aperture images based on diver's lateral hand motion. A transducer only few inches in size is required. Azimuth resolution of about 10 cm is expected at a range of 30 m. A set of motion compensation and scale estimation techniques developed ...
