A direct laser metal sintering process will be developed that will enable the fabrication of complex stainless steel and Inconel alloy components for use in the cores of light water reactors directly from a digital model. Direct fabrication eliminates welding processes that place limits on component design and potentially affect the strength and corrosion resistance of the final component. The tec ...

THIS STUDY IS TO DEVELOP INSTRUMENTATION TO MEASURE DRY DEPOSITION RATES OF ATMOSPHERIC TRACE GASES IM- PORTANT IN STUDIES OF ACIDIC DEPOSITION. THE METHOD IS BASED ON THE WELL-ESTABLISHED EDDY CORRELATION TECHNIQUE AND WILL USE A TUNABLE DIODE LASER SOURCE COMBINED WITH AN OPEN-PATH MULTIPASS ABSORPTION CELL FOR TRACE SPECIES DETECTION AT PARTS-PER-BILLION LEVELS. THIS INSTRUMENT WILL HAVE THE FA ...

The combination of X-ray absorption spectroscopy (XAS) with x-ray emission spectroscopy (XES) provides unique diagnostic analysis of both the structure and chemical composition of complex heterogeneous materials. The penetration of X-rays make this method ideal for studying and optimizing material properties under realistic, real time reaction conditions with simultaneous analysis of r ...

NOVA Scientific proposes the development of efficient position sensitive detectors capable of time-tagging epithermal energy neutrons with high accuracy and efficiency. These devices will be able to perform energy-resolved imaging at the pulsed neutron sources and detect every neutron with spatial resolution of & lt; 60 m and timing resolution & lt; 1 s for thermal neutrons and & lt;100 ns for epi ...

One of the major hurdles to the commercialization of OLED lighting technology is its low light extraction efficiency when compared to its inorganic LEDs. Currently only 20 30% of the light produced by the OLED can be extracted. In order to be considered as a commercially viable option, OLED lighting efficacy has to improve dramatically. The mismatch between the refractive indices among the activ ...

SILICON CARBIDE (SIC) IS AN EXCELLENT MATERIAL FOR THE MANUFACTURE OF HIGH RESOLUTION AND HIGH EFFICIENCY GRATINGS.GRATINGS MADE FROM THIS MATERIAL ARE PARTICULARLY SUITABLE FOR HOSTILE ENVIRONMENTS SUCH AS PLASMA FUSION EXPERIMENTS. THEY WOULD BE RESISTANT TO HIGH ENERGY RADIATION, BE CHEMICALLY INERT, HAVE A HIGH THERMAL CONDUCTIVITY AND A LOWTHERMAL EXPANSION COEFFICIENT, AND THEY ARE POLISHABL ...

AER PROPOSES TO DEVELOP A NEW CONCEPT IN PROVIDING WEATHER \FORECASTING FOR INDUSTRY, MADE POSSIBLE BY THE DECREASING COSTS OF POWERFUL COMPUTERS. IMPROVED SHORT-RANGE FORECASTS WOULD BE OBTAINED BY RUNNING A MODEL ON THE USER'S COMPUTER. THE MODEL WOULD ACCESS THE FORECASTS OF THE NATIONAL METEROLOGICAL CENTER AND MODIFY THEM THROUGH A DETAILED SIMULATION OF THE PHYSICS OF ATMOSPHERIC PROCESSES,T ...

The high energy physics (HEP) community, the scientific and medical communities and the public at large, require the availability of high sensitivity photo- sensors with improved spatial and temporal resolution that can be scaled to large areas, and manufactured in a robust, durable, and compact package at a low cost. Phase I successfully demonstrated the underlying enabling scientific and techni ...

THE SOLAR NEUTRINO PROBLEM IS ONE OF THE LONGEST- STANDING UNRESOLVED PROBLEMS IN THE UNDERSTANDING OF THE ENERGY-PRODUCING PROCESSES IN THE SUN. THE OBSERVED FLUX OF NEUTRINOS IS ABOUT ONE-FOURTH OF THAT PREDICTED BY CAREFUL CALCULATIONS OF SOLAR-FUSION REACTIONS. THE POSSIBILITY OS RESOLVING THIS ISSUE WILL BE STUDIED BY THE USE OF NOVEL NEUTRINO DETECTOR USING INDIUM PHOSPHIDE DETECTORS. IN PHA ...
