This Small Business Technology Transfer (STTR) Phase I project will develop biomass-processing technology for converting crude natural glycerin to antifreeze. The rapidly expanding U.S. biodiesel industry collects millions of gallons of crude glycerin per year as a by-product and much of this glycerin is disposed of as waste. The proposed research will allow the conversion of this crude glycerin ...

We propose to develop a continuous wave terahertz imaging spectrometer tunable from 0.2 to 3 THz in order to remotely detect, monitor and identify chemical and biological agents such as the aerosol simulant Bacillus subtillus. The fully realized systemwill consist of a high brightness THz source illuminating the region of interest and detected by a tunable THz interferometric imaging array. ...

We propose to develop a frequency domain terahertz dual beam spectrometry system tunable from 0.2 to 3 THz with resolution 25M) field detection systems and interferometric imagers to be configured from this technology in phase III.

NASA and the aerospace industry are beginning to utilize terahertz (THz) reflection imaging (for example, examining the space shuttle external tank sprayed on foam insulation for voids and disbonds). THz non destructive evaluation (NDE) imaging is widely applicable to composite resin, ceramic, plastic, natural, and other non-metallic materials. Current commercial equipment is capable of 2D raster ...

This Small Business Technology Transfer (STTR) Phase I project proposes to develop the technological and theoretical foundation of a high-speed terahertz (THz) tomographic non-destructive evaluation (NDE) imaging system. It is proposed to construct and evaluate a multiple THz transmitter and receiver module array test-bed to be employed with a commercially availability spectrometer system. This te ...

We propose to prove the feasibility of using time domain terahertz (THz) non destructive evaluation (NDE) to inspect turbine blade thermal barrier coatings (TBC). High speed, non contact THz inspection will be useful both during the manufacturing process, during maintaince, and during recoating. Low thermal conductivity ceramic coatings that are deposited on Ni-alloy turbine-engine blades to pr ...

We propose to demonstrate the feasibility of an compact optically driven high power time-domain terahertz (TD-THz) source with greater than 1 milliwatt average output at a repetition rate of approximately 50 MHz. This source will be compatible with conventional time domain terahertz spectroscopy and imaging equipment, but extend the output power greater than a 1000 times the 1 microwatt typically ...

In phase II we will develop a prototype high power time domain terahertz (TD-THz) pulse source with a 1 milliwatt average output based on our Phase I approach.    This source will be compatible with conventional time domain terahertz spectroscopy and imaging instrumentation, but extend the output power greater than a 1000 times the 1 microwatt typically generated by conventional systems.  TD-T ...

DESCRIPTION: (Applicant's Description) Ovarian carcinoma (OC) is the fourth most frequent form of cancer death of women in the United States. Approximately 1 in 70 women in the US will develop OC; in advanced stages of the disease there is a 5-year survival of about 15-20%. Present methods of treatment for advanced sta ...
