Mass, quark-number, and sqrt sNN dependence of the second andfourth flow harmonics in ultra-relativistic nucleus-nucleuscollisions
We present STAR measurements of the azimuthal anisotropyparameter v_2 for pions, kaons, protons, Lambda, bar Lambda, Xi+bar Xi,and \Omega + bar Omega, along with v_4 for pions, kaons, protons, andLambda + bar Lambda at mid-rapidity for Au+Au collisions at sqrt sNN=62.4and 200 GeV. The v_2(p_T) values for all hadron species at 62.4 GeV aresimilar to those observed in 130 and 200 GeV collisions. For observedkinematic ranges, v_2 values at 62.4, 130, and 200 GeV are as little as10 percent-15 percent larger than those in Pb+Pb collisions at sqrt s NN=17.3 GeV. At intermediate transverse momentum (p_T from 1.5-5 GeV/c),the 62.4 GeV v_2(p_T) and v_4(p_T) values are consistent with thequark-number scaling first observed at 200 GeV. A four-particle cumulantanalysis is used to assess the non-flow contributions to pions andprotons and some indications are found for a smaller non-flowcontribution to protons than pions. Baryon v_2 is larger than anti-baryonv_2 at 62.4 and 200 GeV perhaps indicating either that the initialspatial net-baryon distribution is anisotropic, that the mechanismleading to transport of baryon number from beam- to mid-rapidity enhancesv_2, or that anti-baryon and baryon annihilation is larger in thein-plane direction.

Natural Analogues of Nuclear Waste Glass Corrosion.
This report reviews and summarizes studies performed to characterize the products and processes involved in the corrosion of natural glasses. Studies are also reviewed and evaluated on how well the corrosion of natural glasses in natural environments serves as an analogue for the corrosion of high-level radioactive waste glasses in an engineered geologic disposal system. A wide range of natural and experimental corrosion studies has been performed on three major groups of natural glasses: tektite, obsidian, and basalt. Studies of the corrosion of natural glass attempt to characterize both the nature of alteration products and the reaction kinetics. Information available on natural glass was then compared to corresponding information on the corrosion of nuclear waste glasses, specifically to resolve two key questions: (1) whether one or more natural glasses behave similarly to nuclear waste glasses in laboratory tests, and (2) how these similarities can be used to support projections of the long-term corrosion of nuclear waste glasses. The corrosion behavior of basaltic glasses was most similar to that of nuclear waste glasses, but the corrosion of tektite and obsidian glasses involves certain processes that also occur during the corrosion of nuclear waste glasses. The reactions and processes that control basalt …

Low-friction coatings for air bearings in fuel cell air compressors
In an effort to reduce fuel consumption and emissions, hybrid vehicles incorporating fuel cell systems are being developed by automotive manufacturers, their suppliers, federal agencies (specifically, the US Department of Energy) and national laboratories. The fuel cell system will require an air management subsystem that includes a compressor/expander. Certain components in the compressor will require innovative lubrication technology in order to reduce parasitic energy losses and improve their reliability and durability. One such component is the air bearing for air turbocompressors designed and fabricated by Meruit, Inc. Argonne National Laboratory recently developed a carbon-based coating with low friction and wear attributes; this near-frictionless-carbon (NFC) coating is a potential candidate for use in turbocompressor air bearings. The authors present here an evaluation of the Argonne coating for air compressor thrust bearings. With two parallel 440C stainless steel discs in unidirectional sliding contact, the NFC reduced the frictional force four times and the wear rate by more than two orders of magnitude. Wear mechanism on the uncoated surface involved oxidation and production of iron oxide debris. Wear occurred on the coated surfaces primarily by a polishing mechanism.

Thermal stability of zirconia-s and thoria-base fuels (LWBR Development Program)
Vapor densities and/or dissociation pressures of UO/sub 2/, ThO/sub 2/, ZrO/sub 2/, ThO/sub 2/-8 and -20 wt % UO/sub 2/, and ZrO/sub 2/-20 and -50 wt % UO/sub 2/ were obtained in the range from 2000 to 3000/sup 0/K by the transpiration technique. The UO/sub 2/-ZrO/sub 2/ system exhibited marked positive deviation from ideality, indicative of a strong tendency toward immiscibility. The UO/sub 2/-ThO/sub 2/ system was found to behave almost ideally. On the basis of the vapor pressures of UO/sub 2/ and of ThO/sub 2/ and the activity values it would be expected that compositions containing 1 mole % or more of UO/sub 2/ would volatilize by preferentially losing UO/sub 2/. A composition containing slightly less than 1 mole % UO/sub 2/ should prove to be the congruently subliming composition. O/sub 2/-dissociation pressures were determined for stoichiometric UO/sub 2/ and for a composition on either side of the stoichiometric one. At 2360/sup 0/K, UO/sub 2.03 +- 0.01/, UO/sub 2.00 +- 0.01/, and UO/sub 1.97 +- 0.01/ exhibited O/sub 2/-dissociation pressures of 1 x 10/sup -7/, 4.3 x 10/sup -10/, and 3 x 10/sup -12/ atm, respectively. From determinations of vapor density and measurements of O/sub 2/ pressure, pressure-temperature-composition relations …
