"Magnetic field-enhanced electrocatalysis at the hydrogen and air electrodes of PEM fuel cells have reported improved power densities, three-fold over conventional PEMFCs. Leddy, et al. used micron-sized polymer-encapsulated beads of permanent magnetsplaced in conventional inks of carbon-supported platinum electrocatalysts to enhance MEA performance. Their work showed a qualitatively improved CO ...

"Reflex triode bremsstrahlung sources potentially provide warm X-ray sources (20 keV to 500 keV), capable of generating high doses (~10 cal/g gold) over exposure areas of ~20 cm2. This needed capability allows experimental verification of warm X-ray inducedthermomechanical response, SGEMP, and box IEMP models for achieving component and system certification to hostile environments.In a reflex trio ...

"Nuclear Weapons Effects Tests (NWET) frequently require that the test article be irradiated in an ultra-clean environment, making survivable shields a necessary part of many debris systems. Survivable shields as large as 12 inches in diameter are requiredbut have yet to be demonstrated in Plasma Radiating Source (PRS) environments. The loads on a survivable shield are a combination of radiation i ...

"Measurements of fluence from a Plasma Radiation Source (PRS) are critical to the performance of accurate Nuclear Weapon Effects (NWE) experiments. Fast, total stopping calorimeters have been demonstrated to provide a robust, reusable, economic sensor forfluence measurements. However, the output of these sensors is a few millivolts and thus high signal to noise recording is difficult to achieve, ...

During this Phase I effort Optomec will demonstrate that the Laser Engineered Net Shaping (LENS) process provides a viable means for both repair and fabrication of functional prototype components for the MPH needs. This work will serve to establish abenchmark part that can be used for calibration and set up of the LENS equipment, as well as other commercially available RP equipment. The goal of ...

"Continuous fiber-reinforced ceramic composites (CFCCs) are inherently wear and oxidation resistant, retain strength at higher temperatures and have lower specific densities than competing metal systems. The hot sections of gas turbine engines and relateddevices are exposed to aggressive gaseous species at high temperature. Because of their thermochemical stability and oxidation resistance, CFCC ...

"Demilitarization of obsolete and aging munitions has slowed dramatically with the loss of open burning and open detonation options. This has created a need for a fast, efficient, environmentally acceptable alternative for explosives removal. Toalleviate this problem, TPL proposes the ultrasonic fracturing and removal of cast explosives from shells in a single remote operation. This will be acc ...
