| 20090044641 | TRACE SAMPLER - A position of an object moving through a region of interest is determined, and at least one source of an air stream is selectively activated based on the determined position. The air stream is capable of dislodging a particle from the object moving through the region of interest. The air stream is directed toward the region of interest. An air collector is selectively activated, based on the determined position, to draw air from the region of interest. The drawn air is deposited on a sample collector, and the sample collector is analyzed to determine whether the deposition of the air stream left particles of a material of interest on the sample collector. | 02-19-2009 |
| 20100240140 | ENERGETIC MATERIAL DETECTOR - A method of detecting energetic materials, such as explosives, includes energizing a sample area that contains particles of energetic materials. In the method, temperature characteristics from the sample area are monitored, and a temperature released from exothermic decomposition of the particles is detected. The method further includes analyzing the detected temperature to determine the presence of the exothermic compound which caused the decomposition. | 09-23-2010 |
| 20110024626 | TRACE SAMPLING - A trace sampling detection system includes a gathering device configured to gather particles through a handle-bar, a gate and an air-stream gatherer. The handle-bar includes collection holes positioned to be adjacent to a user's hand when the user grips the handle-bar, and is configured to dislodge and capture particles from the user's hand when the user grips and moves the handle-bar. The gate includes a series of collection holes, is positioned to be adjacent to the user's clothing when the user traverses the gate, and is configured to dislodge and capture particles from the user's clothing in response to pressure applied from the user. The air-stream gatherer includes an outward vent and an in-drawing vent, and is positioned to enable objects, such as the user's feet, to be placed between the outward and in-drawing vents. The air stream is configured to dislodge and capture particles from objects, such as the user's feet, that block the air-stream between the vents. A collection tube is configured to deposit gathered particles from the gathering device onto a portion of a sample media. A carousel wheel that includes the sample media is configured to rotate the sample wheel such that the portion of the sample media including the gathered particles is presented to an exothermic decomposition detector that detects, through an infrared sensor, the decomposition of the gathered particles. | 02-03-2011 |

| 20090218543 | CATALYTIC NANOPARTICLES FOR NERVE-AGENT DESTRUCTION - The present invention relates to compositions and methods for sorbing (e.g., adsorption and chemisorption) and destroying organophosphate chemical agents. In certain embodiments, the invention contemplates the use of finely divided, modified nanoscale metal oxide particles. In one embodiment, a suspension of magnetite (Fe | 09-03-2009 |
| 20100222519 | Responsive Materials for Isolating Organic Compounds - One aspect of the present invention relates to polymers containing redox-responsive moieties (such as, ferrocene). In certain embodiments, the present invention relates to in-situ continuous separation systems which use such redox-responsive polymers for low-molecular weight alcohol removal from an aqueous mixture; such systems enhance the production of low-molecular weight alcohols by reducing the product inhibition effects that plague their production from bio-mass by fermentation. | 09-02-2010 |
| 20100285081 | Bactericidal Nanofibers, and Methods of Use Thereof - One aspect of the invention relates to an antimicrobial fiber formed from an electroprocessed blend of at least one polymer, at least one antimicrobial agent, and at least one crosslinker. Another aspect of the invention relates to an antimicrobial fiber formed from an electroprocessed blend of at least one polymer and at least one crosslinker, which is then coated with an antimicrobial compound or antimicrobial polymer. | 11-11-2010 |
| 20110027869 | Compositions for Chemical and Biological Defense - One aspect of the present invention relates to reactive compositions and methods of use thereof, wherein a metal oxide cluster is used to connect a reactive group (or groups) to the surface of a substrate. In certain embodiments, the reactive group in the compositions decomposes organophosphate agents through nucleophilic hydrolysis. In certain embodiments, the reactive group in the compositions is bactericidal. Remarkably, the use of metal oxide clusters in the disclosed compositions and methods permits incorporation of higher quantities of nucleophilic and bactericidal groups without the difficulties associated with having to pretreat the substrate prior to its association with the reactive groups. | 02-03-2011 |
