Company: Ftc Acquisition Corp Agency/Program/Year/Phase: DOD / SBIR / 1993 / 1
Abstract: This program will demonstrate the applicability of the freeze crystallization (FC) process dirctly to U.S. Air Force environmental managers by, in phase I, (1) finding applications that are well served by this technology, (2) demonstrating the capabilities of the FC process by processing wastes in… more
Company: Ftc Acquisition Corp Agency/Program/Year/Phase: DOD / SBIR / 1993 / 1
Abstract: When loading nitrogen tetroxide before launching the space shuttle, fugitive N2O4 is absorbed into caustic solutions in a two stage scrubber solution. The second stage of the scrubber has sodium sulfite added to the alkaline scrubbing solution to act as an oxidant scavenger, to improve scrubbing… more

Abstract: N/A
Company: Novel Pharmaceuticals Agency/Program/Year/Phase: HHS / SBIR / 1993 / 1
Abstract: The intent is to create an artificial intelligence software system which accurately predicts chemical toxicity. The system will use a neural network to recognize patterns and correlation between chemical structure/substructures, physicochemical properties, and toxicologic/carcinogenic findings. An… more
Company: Pathology Associates, Inc. Agency/Program/Year/Phase: HHS / SBIR / 1993 / 1
Abstract: Increasing evidence suggests that chemically-induced cell proliferation plays a role in carcinogenesis. The complex relationships between chemically-induced mutations, cytotoxicity, cell proliferation and carcinogenesis are important considerations in setting doses for cancer bioassays, classifying… more
Company: POWER TECHNOLOGY SERVICES (PTS), INC. Agency/Program/Year/Phase: DOD / SBIR / 1993 / 1
Abstract: This proposal is for the development of an optically activated high voltage semiconductor switch device capable of switching loads on and off within nanoseconds or picoseconds. A device of this type would not be possible using the existing limitations imposed by the limited knowledge on the… more

Search Options

There are several categories such as “By Agency”, “By Year”, “By State” etc. Select a checkbox within a category to refine your search results.

Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.


Search for Either Criteria

When you select multiple values within a category, the results will include values that match either of the selections. For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.


Narrowing the Search Results

You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories. For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
