78363S In order to perform physics experiments with higher energy collisions, more energy and luminosity will be required. More luminosity means larger apertures and bigger magnets. In turn, the development of high field magnets will require higher performance, lower cost Nb3Sn superconductors. This project will develop and demonstrate an economical powder-in-tube (PIT) Nb3Sn process for use i ...

THE MASS OF DNA SEPARATED BY GEL ELECTROPHORESIS CAN BE DETERMINED FROM THE INTENSITY OF THE FLUORESCENCE OF A DNA-SPECIFIC DYE EXCITED BY UV RADIATION. THE PRESENT USE OF PHOTOGRAPHIC FILM TO RECORD THE FLUORESCENCE LIMITS THE ACCURACY, SENSITIVITY, AND DYNAMIC RANGE OF THE ANALYSIS. ALTERNATE SCANNING SYSTEMS THAT DIRECTLY DETECT THE FLUORESCENCE ARE SLOW. A NEW IMAGING SYSTEM IS PLANNED TO MEAS ...

THIS PROJECT ADDRESSES THE NEED FOR MAGNETIC FIELD AND CURRENT MEASUREMENT DEVICES FOR FUSION PLASMA DIAGNOSTICS, ESPECIALLY IN THE COMPACT IGNITION TOKAMAK (CIT). FIBER OPTIC MAGNETIC FIELD SENSOR DEVELOPMENT IS PLANNED TO TAKE ADVANTAGE OF THE HIGH SENSITIVITY, HIGH TEMPERATURE, RADIATION RESISTANCE, AND DIELECTRIC PROPERTIES OF THE OPTICAL FIBER. THE HIGH SENSITIVITY AND LARGE DYNAMIC RANGEWILL ...

78072S III-V nitride-based, high brightness, UV and visible light emitting diodes (LEDs) are of a great interest for general illumination, but the low light output efficiencies of current high brightness LEDs are still inadequate. A key material issue preventing the achievement of higher light output efficiency in LEDs is the poor crystalline quality of the nitride epitaxial layers that result fr ...

79758B Safety concerns over the susceptibility of large Li-ion cells to thermal runaway during overcharge are one of the problems preventing the commercialization of these cells. This problem will be addressed by developing new materials that will be substituted for the cell component believed to be involved in the runaway process. In particular, electrolyte systems that form less a resistive i ...

79454S Despite advances in modern electron optics, which have permitted observation with unprecedented resolutions, most materials science research involves the quantification of static properties of materials. This is mostly due to limitations in modern day equipment and the time and cost associated with modifying existing microscopes. Consequently a need exists to extend the current ability t ...

79729S Ocean currents constitute a potentially enormous renewable energy resource; however, existing technologies for capturing this energy are only in the prototype stage, are small in scale (less than 1 megawatt), and are not grid-connected. Although there is a considerable overlap in technology with the more mature field of wind energy, new robust technologies will have to be developed that ar ...
