Sepax Technologies, Inc. has identified a new type of anoin-exchange resin which separates single-wall carbon nanotubes (SWCNTs) with >80% recovery yield and resolves in a single pass the chiral tubes of (6,5) well from commercial SWCNT starting materials by Chromatography. Improvement and scale up of the targeted resin production will facilitate the separation of chiral nanotubes for the academic ...

X-ray fluorescence spectroscopy is a widely used and extremely sensitive analytical technique for qualitative as well as quantitative chemical analysis. Superconducting Transition Edge Sensor (TES) microcalorimeter detectors have now been developed that achieve an energy resolution of 2 eV (full width at half maximum) for 1.5 keV X-rays, which is sufficient to enable the measurement of the small s ...

Propagation Research Associates, Inc., (PRA) proposes to utilize its unique capabilities in atmospheric effects characterization and GPS signal processing to develop algorithms that nowcast ionospheric scintillation at GPS frequencies. To this end, PRA proposes to partner with the Jet Propulsion Laboratory to use real-time GPS data to create a map of ionospheric scintillation parameters over the ...

NanoPlatelets (NPs) created of metal hydroxides present entirely new and previously unknown set of morphologes/properties and are a virtually new frontier and unstudied field of Material Science and may be leveraged into many of todays DoD and Comercial Technical Challenges and applications. Case in point is SOCOM's Defense Mitigation and Decontamination of military aircraft and equipment and ...

Stochastic parameterization of large scale models is becoming an important tool for evaluating climate predictability and for enabling accurate representation of effects of micro-scale and short time physics on long time climate statistics. The models currently used to evaluate climate risk do not incorporate these stochastic effects, but represent multi-year development and collaboration between ...

MRC PROPOSES TO DEVELOP A SAFETY PERFORMANCE INDICATOR (PI) OF THE ELECTROMAGNETIC (EM) PROTECTION STATUS OF A NUCLEAR POWER PLANT (NPP). WE BELIEVE THAT SUCH A PI IS NEEDED BECAUSE: (1) EM ENVIRONMENTAL POLLUTION IS ON THE INCREASE,(2) ADDITIONAL EM THREATS MUST BE EVALUATED, AND (3) DISRUPTION OF NPP OPERATIONS BY EM EFFECTS CAN AND MUST BE AVOIDED. PREVIOUS STUDIES HAVE ADDRESSED THE ISSUE OF E ...

TWO APPROACHES WILL BE EXAMINED TO SIGNIFICANTLY IMPROVE THESENSITIVITY OF LAUNDRY MONITORS TO DETECT AND SPECIFY LOCATION OF HOT PARTICLES ON LAUNDERED GARMENTS. THESE PROPOSED TECNIQUES HAVE HIGH POTENTIAL FOR DETECTING BOTH LOW ENERGY BETA AND ALPHA PARTICLE RADIATION AS WELL AS IMPROVING SENSITIVITY BY REDUCING BACKGROUND COUNT RATE.

THE UNCERTAINTY IN MEASURING NEUTRON DOSE EQUIVALENT RATES RESULTS IN UNCERTAINTY IN ASSIGNMENT OF THE PROPER DOSE TO OCCUPATIONAL RECORDS AND CAN RESULT IN IMPROPER IMPLEMENTATION OF CONTROLS TO LIMIT THE EXPOSURE. A NOVEL PORTABLE NEUTRON SPECTROMETER IS PROPOSED WHICH WILL REDUCE THE UNCERTAINTY OF SUCH MEASUREMENTS TO LESS THAN 20%. MANYCOMPONENTS OF THIS DEVICE ARE COMMERCIALLY AVAILABLE. SYS ...
