There are many products that can identify chemical weapons. They range in complexity from simple colorimetric chemical test strips or gas tubes, to more complex multi-step test kits, to intricate arrays of gas chromatographs and mass spectrometers. None of the products is specifically designed to illustrate the presence of chemicals on surfaces or have use as a decontamination assurance method. ...

DNA microarray technology, in combination with statistical and predictive modeling tools, could be used to evaluate thousands of genes against distinct gene expression patterns induced by chemical/biological agents to provide early identification and speed therapeutic intervention. The overall objective of this Phase II effort is to leverage existing public domain resources and commercial tools t ...

By continuing teaming up with one of the most reputable university teams in THz science and technology, ArkLight proposes to carry out the tasks set for a Phase-II program following our success in Phase I. We are aimed at the further development of novel spectrometers to analyze chemicals in the vapor phase based on accurate measurements of the emission and absorption spectra due to the molecular ...

The task of computationally simulating the dispersion and/or neutralization of toxic chemical/biological (CB) agents, released from weapons of mass destruction (WMD), puts a very high demand on the capability of current generation computational dynamics (CFD) codes. Current advanced computational tools for WMD threat simulation fail to address the necessary physics, do not incorporate emerging com ...

We propose to develop reactive composite materials with sufficient strength and stiffness to serve as structural components for penetrating weapons and other munitions. The composites will consist of two materials that react with each other, in either oxidation-reduction (such as in a thermite) or bimetallic reactions. One component will be in the form of fiber, wire, or wire-mesh, within a bondin ...

A NOVEL SET OF HIGHLY EXOTHERMIC AND ESSENTIALLY GASLESS (CONDENSED PHASE) REACTIONS WILL BE INVESTIGATED IN ORDER TO SELECT THE COMPOSITION WHICH PROVIDES THE MOST APPROPRIATE METHOD OF SIMULATING RADIANT FLUXES EQUIVALENT TO THOSE ENCOUNTERED IN NUCLEAR AIR BLASE ENVIRONMENTS. THE PROPOSED CONCEPT IS CAPABLE OF GENERATING PEAK TEMPERATURES IN EXCESS OF 3200 DEG K AND RADIATION FLUXES UP TO 200 C ...

Improvements and refinements in formulation and configuration of current thermobarics are presented. Improvements in formulation allow for faster reaction rates and more complete reaction, releasing a greater percentage of available energy at early times and close to the HE detonation step. Furthermore, improvements in configuration will allow faster mixing rates, resulting in a reduction in total ...

To address the needs of the Defense Threat Reduction Agency (DTRA), GSI will perform in three areas during the course of this effort. 1) GSI will evaluate a new formulation, capable of self-propagating reaction with the production of an electrically conductive aerosol, for the purpose of Intrusive Electronic Equipment Defeat. This material will be evaluated against electronic equipment (PC's) and ...

The pressing need exists within industry to accurately measure high aspect ratio microscale structures. For example, diesel injector nozzles are manufactured with microscale holes ranging from 50-200 micrometers in diameter and 3-5 mm depths. One fundamental challenge is to nondestrucvely measure these features in order to validate models, enhance manufacturing processes, and reduce fuel emissions ...

INADEQUATE STARTER FEEDS SEVERELY HOLD BACK NEW AQUACULTURE ENTERPRISES SUCH AS PRESENT ATTEMPTS TO RAISE FISHES WHOSE LARVAE DEVELOP FROM SMALL EGGS AND HAVE VERY "DIFFICULT" FOOD REQUIREMENTS. INERT LARVAL FEEDS HAVE NOT SUCCESSFULLYELIMINATED THE STRICT DEPENDENCY ON NATURAL FORAGE DURING THE CRITICAL POST-LARVAL STAGE AFTER YOLK ABSORPTION AND BEFORE THE DEVELOPMENT OF A DIGESTIVE SYSTEM WITH ...
