NIST is using a sensitive optical technique called cavity ring-down detection to permit detection of impurities in semiconductor process gases, which cause substantial losses in manufacturing yield. In order to increase the sensitivity and range of application of this technique, improved single frequency laser sources are required. In particular, lasers providing more power, narrower line-width, b ...

B.E. Meyers & Company proposes to deliver the Phase I requirements of the AVPAS by utilizing its research and development resources to examine new technologies, architectures, and designs. These efforts will result in providing to the government the market research, proof-of-concept analysis, and a proposed design for an AVPAS prototype. The prototype design will be founded on incremental testin ...

The technology to be developed in the Phase I efforts is based on prior research in Electromagnetic (EM) gradiometry and Resonant Microstrip Patch Antenna (RMPA). The combination of these approaches has been used in successful demonstrations in the mining industry for determining coal depth and scanning ahead for barriers/obstructions. Each technology has been proven to mitigate specific problems ...

Current bioaerosol monitoring strategies rely on inertia-based sampling and suffer from high power consumption and low efficiency limitations. In contrast, our overall objective is to design and demonstrate a novel electrostatic sampler that provides dramatic improvements including low power requirement (90% for 1-10mm), high viability (>80%), scalability for varying threat scenarios, low noise, a ...

The proposed project will develop a novel aerosol concentrator based on aerodynamic lens technology capable of achieving very high concentration factors in a compact device. This device will be fabricated in silicon using micro-fabrication methods resulting in low cost, compact size, high reliability, high throughput, and extremely high precision and repeatability. In this project we will develop ...

InnovaTek proposes to develop an advanced, low cost aerosol collector/concentrator that utilizes electrostatic precipitation and cyclonic impingement with a virtual impactor pre-concentrator that will have >90% collection efficiency while operating at 1000 LPM using less than 50 watts of power. Technology will be designed on the basis of first principles and computational fluid dynamics modeling. ...

This proposal addresses the development of an advanced polymer-based system which possesses a reactive feature that serves to neutralize chemical agents and toxic industrial chemicals in-situ and on contact. The polymer system is designed to facilitate a rapid return-to-service of the contaminated area, such that emergency, rescue and other first response activities can take place safely during th ...

Many integrated biodetection systems require an aqueous sample, with the notable exception being those based on mass spectrometry which frequently uses a dry sample (MALDI or pyrolysis). The two proposed air sampling technologies to be developed are amenable to dry or nearly dry sample collection, but yet both can deliver a final sample in an aqueous format autonomously. Furthermore, both offer si ...

On-site generation technology utilizes common salt (sodium chloride) which is made in to a dilute brine solution that is converted in an electrolytic cell to a chlorine-based liquid disinfectant. The chlorine component is important since the US EPA requires a chlorine disinfection residual value in drinking water in the United States. There are no hazardous materials used, consumed or produced in ...

Active cooling of HAZMAT and SWAT team members can significantly improve their performance in critical situations. However, current cooling systems are heavy, bulky, and don`t provide adequate cooling rates. By employing a new meso-channel adsorption bed using high capacity, sheet desiccants operated in a ambient-air cooled cross-flow mode, cooling capacities of 50 to 125 W can be generated with w ...
