The primary goal of this proposed work is to develop a long wavelength infrared (LWIR) colloidal quantum dot (CQD)-based focal plane array (FPA) and show its feasibility when used in a camera system and a hyperspectral imaging system. Phase I results cumulated in the first-ever synthesis of photoresponsive LWIR CQDs and CQD-based photodetectors at the single device level operating at room temperat ...

We propose an Acousto-Optic Tunable Filter (AOTF) Spectropolarimetric Imaging System for Enhanced Standoff Chemical Detection at Long Wave Infrared (LWIR) wavelengths. This work entails development of suitable LWIR material, design of the LWIR AOTF, and design of the hyperspectral imaging sensor using a focal plane array. Currently, there is no technologically mature, commercially available mater ...

We propose to develop low cost Long Wavelength Infrared Focal Plane Arrays (LWIR FPAs) using colloidal quantum dots (CQDs) of mercury telluride (HgTe). In Phase I, QDs in the size range of 20-25nm (corresponding to cutoff wavelength of 8 to 12 microns) w...

A technology for continuous ionization of bio-aerosols and airborne particles to improve the effectiveness of its electrostatic collection was demonstrated in Phase I. We designed, fabricated and tested a 50 CFM device that uses direct induction charging...

In Phase I RANCOR successfully demonstrated an innovative enabling humidity control technology to provide very low humidity air to water sensitive, fully reusable CO2 adsorbents. The use of adsorbents enables complete reusability/rechargability and reduces the total heat load on the SCBA to the point where ice or other cooling systems will no longer be required. In Phase II Paragon will introduce ...

The in situ production of biocidal reactive oxygen via directed energy work will develop a benign, environmentally safe decontamination solution. The effort will demonstrate the potential to produce biocidal reactive oxygen and thermal effects via exposure to radio frequency directed energy at two frequencies to kill bacterial (Bacillus thuringensis) and mold (Penicillium sp.) spores. Controlled ...

Accurate, realtime detection of explosives is a demanding application. High detection accuracy with a low false positive rate is desired. Noise and artifacts in reconstructed images, especially in the presence of metal, degrade the ability of detection algorithms to identify object's shape, volume, and composition. Model-based iterative reconstruction (MBIR) has been demonstrated to improve i ...

The proposed SBIR phase I project will demonstrate a ultra-small, low-power, low-cost solution for detection of toxic gases and particulate matter (PM) in air. Firefighters are exposed to various toxic gases and PM both during active knock-down and overhaul phases of fire operation. Four-gas toxic monitors, commonly used by firefighters, are ineffective due to limited information it can provide, ...

The proposed goal of Nevada Nanotech Systems Inc for the Phase II program is to adapt a commercially available gas chromatograph-mass spectrometer instrument for the problem of detecting U.S. currency via unique vapor signature in confined spaces and then field test three prototype units, operated by government personnel, during a 6-month field test. After this test, we will provide detailed docu ...

The development of the Zeteo Toxic Agent Detection System (zTADS) is presented here. The system features a multiplexed disposable sample collection and processing system that feeds a handheld biological mass spectrometer.
