The overall objective of this project was to validate the concept and application of a functional interconnect, based on a ferritic stainless steel, for a solid oxide fuel cell through manufacturing trials, laboratory testing, and field experience. The materials of construction and their surfaces were to be optimized…
A C60-cyclopentadiene cycloadduct was readily synthesized, by a Diels-Alder reaction between C60 and freshly cracked cyclopentadiene. The functionalized C60 and norbornene were then pre-mixed in varying molar ratios and co-polymerized using a ROMP approach with catalytic amounts of Grubbs second generation catalyst. A…
This paper examines two coal-based hybrid configurations that employ separated anode and cathode streams for the capture and compression of CO2. One configuration uses a standard Brayton cycle, and the other adds heat recuperation ahead of the fuel cell. Results show that peak efficiencies near 55% are possible, regar…
Saltstone waste form was prepared in the Savannah River National Laboratory (SRNL) from a Tank 50H sample and Z-Area premix material for the fourth quarter of calendar year 2010 (4QCY10). After the prescribed 28 day cure, samples of the saltstone were collected, and the waste form was shown to meet the South Carolina…
Abstract The infrared luminescence of vanadium‐doped gallium nitride (GaN:V) grown by metalorganic vapour phase epitaxy technique (MOVPE) on SiN‐treated sapphire substrate were examined. Two spin allowed transitions were observed at 6633 cm‐1 and 6959 cm‐1, and are respectively assigned to the 4T1(4P)→4T1(4F) and 4A2(…
Dans cette thèse expérimentale, on s'intéresse aux collisions de gouttes mettant en jeu des interfaces asymétriques, soit deux gouttes constituées de liquide différent ou des gouttes de taille différente et recouvertes (ou non) d'une couche de particules hydrophobes. Dans une première partie, on étudie les collisions…
We report a method to locally measure the penetration depth $λ$ in a superconductor by detecting the diamagnetic response using magnetic force microscopy (MFM). We extract $λ$ by fitting the height dependence of the levitation force in the Meissner state using an analytical model that approximates the MFM tip as a sin…

Phosphorus (P) is a requirement for biological growth, but this vital nutrient is present at low or limiting concentrations across vast areas of the global surface ocean. Inorganic polyphosphate (poly-P), a linear polymer of at least three orthophosphate units, is one component of the marine P cycle that has been rela…
The effect of copper oxide on migration and interaction of protons in barium zirconate was investigated using density functional theory. One copper atom was substituted for a zirconium atom site, and a proton was added to a 3 3 3 barium zirconate superstructure. An energy barrier of 0.89 eV for proton migration was th…

Interior permanent-magnet synchronous motors (IPMSMs) produce both magnetic and reluctance torques. The reluctance torque is due to the difference between the d- and q-axis inductances based on the geometric rotor structure. The steady-state performance analysis and precise control of the IPMSMs greatly depend on the…

Of all the terrible news from the crippled Fukushima Daiichi nuclear power plant, reports about the spent fuel storage pool for reactor #4 may be among the most disconcerting for scientists.
