Use of chromates as corrosion inhibi.tors in coatings, adhesives and sealants is a well established technology. However, toxicity and waste disposal problems have led to the urgent need for development of an environmentally benign substitute for chromium compounds in coatings and sealants, which is the subject of this SBIR. This pa'per discusses the state-of-the-art technical approaches to the sol ...

A NUMBER OF ORGANOPHOSPHORUS COMPOUNDS ARE HIGHLY TOXIC AS A RESULT OF THEIR ABILITY TO INHIBIT CHOLINESTERASES. THIS TOXICITY HAS LED TO THE WIDESPREAD USE OF THESE COMPOUNDS AS PESTICIDES AND SUGGESTS THEIR POTENTIAL USE AS AGENTS OF CHEMICAL WARFARE. A NUMBER OF BACTERIAL SPECIES ELABORATE ENZYMES, TERMED ORGANOPHOSPHORUS ACID (OPA) ANHYDRASES, CAPABLE OF DETOXIFYING THESE COMPOUNDS. THE GOALS ...

This proposal represents a joint small business/university development effort to investigate the problem of plant health monitoring and to evolve a preliminary design of a spectral imaging system. Biotronics Technologies, as the small business SBIR proposer, has extensive background in the development of spectral and spatial imaging systems and has proven its capability to convert a set of require ...

Surface Acoustic Wave (SAW) devices have shown some promise as specific gas detector/analyzers for a number of applications. These sensors operate as dual oscillators in which one SAW is coated with a sorbent material specific to c particular gas. The frequency of the coated oscillator changes with gas concentration while the uncoated reference oscillator does not. The difference between the frequ ...

Site characterization to detect subsurface contamination is of a enormous interest for both public and private applications. Biotronics is proposing to adapt an arc excitation spectrometry technology originally developed for anlaysis of liquid nutrient solutions at NASA to the detection of heavy metals in soils. A preliminary design will be defined that will permit arc excitation of soil adjacent ...
