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 ...

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 ...

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 ...

This Small Business Technology Transfer (STTR) Phase I project is focused on the development of a unique diamond carbon coated graphite-copper composite material. The composite material will be used to produce low thermal resistance packaging components for use in RF power amplifiers. Under the Phase I effort, a low-cost diamond carbon coating process will be demonstrated. There is a critical need ...

This Small Business Innovation Research (SBIR) Phase II project seeks to develop an unique hot press die casting technology to be used to produce graphite-metal materials. These materials will be used to produce packaging components for use in high power electronics packaging. There is a critical need for advanced materials with improved thermal properties capable of meeting the thermal management ...

WE PROPOSE HERE TO OBTAIN FULLY THREE-DIMENSIONAL FIELDS OF TEMPERATURE FROM OBSERVED SATELLITE RADIANCES BY USING VARIATIONAL METHODS WHICH GENERALIZE WAHBA AND WENDELBERGER (1980). WE RECOGNIZE FROM THE START THAT RADIANCES OR THE EQUIVALENT BRIGHTNESS TEMPERATURES ARE ONLY PROXY DATA FOR TROPOSPHERIC TEMPERATURES AND THAT THE DERIVED TEMPERATURES WIL DEPEND UPON THE A PRIORI INFORMATION INCLUDE ...
