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 ...

This program seeks to develop and demonstrate, in severe mechanical shock environments, a new state-of-the-art data recorder for environmental measurements of warhead systems. The developed DSR data record will include 4 internal channels for measuring acceleration, weapon case strain, or pressure and 6 external input digital channels for other user defined measurements. High sampling rates will ...

INTEGRATED CIRCUIT (IC) PRODUCTION LINES OPERATING UNDER MIL-I-38535 HAVE RADIATION HARNESS ASSURANCE (RHA) AND RELIABILITY DESIGNED AND BUILT INTO THEIR TECHNOLOGY. HARDNESS AND RELIABILITY ARE MAINTAINED BY APPLYING STATISTICAL PROCESS CONTROLS (SPCS) TO TEST STRUCTURES FABRICATED ALONGSIDE PRODUCT MICROCIRCUITS. MEASUREMENT AND DATA REDUCTION TECHNIQUES PRESENTLY EMPLOYED ARE SLOW AND COSTLY AN ...

THE DEFENSE NUCLEAR AGENCY (DNA) IS DEVELOPING THE OPERATIONAL MESOSCALE ENVIRONMENT MODEL WITH GRID ADAPTIVITY (OMEGA) TO PREDICT REAL-TIME DISPERSAL OF HAZARDOUS AEROSOLS. ONE REQUIREMENT FOR OMEGA OR ANY SIMILAR MODEL IS TO PREDICT COLLATERAL EFFECTS FROM STRIKES ON NUCLEAR, BIOLOGICAL, AND CHEMICAL (NBC) FACILITIES. THE OBJECTIVE OF THE PROPOSED PHASE I PROGRAM IS TO DETERMINE THE ESSENTIAL FE ...

THE DIFFICULTY IN PREDICTING STRUCTURAL DEGRADATION RATES FOR NUCLEAR POWER PLANT COMPONENTS DUE TO CORROSION AND OTHER FACTORS HAS LED TO THE NEED FOR COSTLY, TIME CONSUMING INSPECTIONS AND INCREASED COST FROM INTENTIONALLY OVERDESIGNED COMPONENTS. THE SITUATION INDICATES A SERIOUS, UNMET NEED FOR A SIMPLE BUT ACCURATE SYSTEM FOR REAL- TIME, IN SITU, NONDESTRUCTIVE ANALYSIS OF NUCLEAR POWER PLANT ...

THE PROPOSED EFFORT WILL DEVELOP AND APPLY A NEW EXPERIMENTAL APPROACH TO MEASURE UNDERWATER TIME RESOLVED SHOCK WAVE PROFILES RESULTING FROM UNDERWATER OR SURFACE DETONATIONS. EXPLICIT DATA REQUIRED TO DESCRIBE UNDERWATER SHOCK WAVE EFFECTS ON TARGETS WILL BE OBTAINED USING A RECENTLY DEVELOPED PIEZOELECTRIC POLYMER STRESS GAUGE. A UNIQUE EXPERIMENTAL CONFIGURATION IS PROPOSED, THAT WILL ALLOW SH ...

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 ...
