Tank 30 and 37 Supernatant Sample Cross-Check and Evaporator Feed Qualification Analysis-2012

This report summarizes the analytical data reported by the F/H and Savannah River National Laboratories for the 2012 cross-check analysis for high level waste supernatant liquid samples from SRS Tanks 30 and 37. The intent of this Tank 30 and 37 sample analyses was to perform cross-checks against routine F/H Laboratory analyses (corrosion and evaporator feed qualification programs) using samples collected at the same time from both tanks as well as split samples from the tanks.

Integrated genome based studies of Shewanella ecophysiology (open access)

Integrated genome based studies of Shewanella ecophysiology

Progress is reported in these areas: Regulation of anaerobic respiration by cAMP receptor protein and role of adenylate cyclases; Identification of an octaheme c cytochrome as the terminal sulfite reductase in S. oneidensis MR-1; Identification and analysis of components of the electron transport chains that lead to reduction of thiosulfate, tetrathionate, and elemental sulfur in MR-1; Involvement of pili and flagella in metal reduction by S. oneidensis MR-1; and work suggesting that HemN1 is the major enzyme that is involved in heme biosynthesis under anaerobic conditions.

Science Drivers and Technical Challenges for Advanced Magnetic Resonance (open access)

Science Drivers and Technical Challenges for Advanced Magnetic Resonance

This report recaps the "Science Drivers and Technical Challenges for Advanced Magnetic Resonance" workshop, held in late 2011. This exploratory workshop's goal was to discuss and address challenges for the next generation of magnetic resonance experimentation. During the workshop, participants from throughout the world outlined the science drivers and instrumentation demands for high-field dynamic nuclear polarization (DNP) and associated magnetic resonance techniques, discussed barriers to their advancement, and deliberated the path forward for significant and impactful advances in the field.

Observation of Non-Maxwellian Electron Distributions in th e NSTX Divertor

The scrape-off layer plasma at the tokamak region is characterized by open field lines and often contains large variations in plasma properties along these field-lines. Proper characterization of local plasma conditions is critical to assessing plasma-material interaction processes occuring at the target. Langmuir probes are frequently employed in tokamak divertors but are challenging to interpretation. A kinetic interpretation for Langmuir probes in NSTX has yielded non-Maxwellian electron distributions in the divertor characterized by cool bulk populations and energetic tail populations with temperatures of 2-4 times the bulk. Spectroscopic analysis and modeling confirms the bulk plasma temperature and density which can only be obtained with the kinetic interpretation
