High-resolution scintillation crystals and crystal arrays are important components of current and future handheld and arrayed detectors (used for DOD/DTRA applications), and scintillation spectrometers (routinely used in high energy physics research, medical imaging, diffraction, homeland security, nuclear waste clean-up, nuclear treaty verification and safeguards, and geological exploration). Un ...

Airborne chemical and biological (CB) agents released in one section of a building travel via the building’s heating, ventilating, and air conditioning (HVAC) systems and disperse throughout the building, while undergoing deposition and resuspension recurrently. Computational fluid dynamics (CFD) has been employed to simulate dispersion of CB agents in a building through HVAC systems. How well t ...

Physical Sciences Inc. proposes to continue development of a software tool that is capable of defining the selection and placement of a constellation of standoff and point sensors for the protection of base facilities and forces deployed in the field. The network will be defined using an algorithm that optimizes the collective performance of the sensors as a function of deployment need, geography, ...

Spectral Sciences Inc. proposes to develop a prototype sensor for real-time trace-level analysis of complex multicomponent gas mixtures, specifically those containing Chemical Weapon (CW) agents and interferents. The instrument is based on high power quantum cascade lasers and photocoustic spectroscopy detection. Advanced detection algorithms take advantage of wide spectral coverage to provide hi ...

Until now gamma radiation detection has required large single crystals of sensitive materials that are difficult to produce consistently on an industrial scale. In collaboration with a research group at the University of Texas at Arlington, Agiltron proposes to develop a new class of nanocomposite scintillator materials. The radiation detection characteristics of the synthetic nanoparticles in the ...

Doctrine for employment of canines in a CBRN environment has evolved into a Collective Protection approach. Providing COLPRO has several very significant implications for Canine kennels and shelters: „X The outer surface of the structure must be CB agent impervious „X The outer surface of the structure must resist effects of the decontamination process „X The system must provide the animal ...

MANAGEMENT OF HEALTH RISKS EMANATING FROM CONTAMINANTS IN DRINKING WATER REQUIRES KNOWLEDGE OF THE IMPACTS OF WATER QUALITY IMPROVEMENTS ON HOUSEHOLD WATER BILLS. FACTORS AFFECTING HOUSEHOLD WATER BILLS VARY SYSTEMATICALLY FROM PLACE TO PLACE. BY MODELING THESE FACTORS IT IS POSSIBLE TOPREDICT IMPACTS FROM IMPLEMENTING CONTAMINANT REMOVAL MEASURES. THE PROPOSED RESEARCH FOCUSES ON: 1) IMPROVEMENTS ...

MICRO-DIFFRACTION-BASED CRYSTALLOGRAPHY IS ESSENTIAL TO MATERIALS DESIGN AND PROCESS UNDERSTANDING IN KEY INDUSTRIAL APPLICATIONS SUCH AS MICROELECTRONICS, SUPERCONDUCTIVITY, SOLAR ENERGY, STRUCTURAL COMPOSITES, AND METAL FORMING. THE SCANNING ELECTRON MICROSCOPE (SEM) CAN PROVIDE HIGH SPATIAL RESOLUTION CRYSTALLOGRAPHIC INFORMATION, BUT ITS APPLICABILITY IS LIMITED BY THE LOW SENSITIVITY OF EXIST ...
