Final Technical Report, Outstanding Junior Investigator Award for De-fg02-94er40869

Description: This report summarizes the research of the Principal Investigator, his postdoctoral research associates, and his students during the period of the award. The majority of the work concerns the behavior of hadrons containing strange, charm, bottom and top quarks, with a particular focus on the extraction of Cabibbo--Kobayashi--Maskawa matrix elements from experiments performed on such systems.

USXR Based MHD, Transport, Equilibria and Current Profile Diagnostics for NSTX. Final Report

Description: The present report resumes the research activities of the Plasma Spectroscopy/Diagnostics Group at Johns Hopkins University performed on the NSTX tokamak at PPPL during the period 1999-2009. During this period we have designed and implemented XUV based diagnostics for a large number of tasks: study of impurity content and particle transport, MHD activity, time-resolved electron temperature measeurements, ELM research, etc. Both line emission and continuum were used in the XUV range. New technic… more

Photoinduced nucleation: a new technology for the detection of chemical contaminants. Final Report

Description: This research grant supported the creation and initial development of a new kind of chemical detector; one that can detect species at part per trillion levels because it does not rely on the direct measurement of a species presence; rather, it uses an indirect measurement of the effect of the trace species on the condensation nucleation of a supersaturated vapor. Since this nucleation process is extremely sensitive to the concentrations of certain types of impurities, this nucleation-based dete… more

Search for the microscopic origin of defects and shear localization in metallic glasses

Description: This proposed research addresses one of the long outstanding fundamental problems in materials science, the mechanisms of deformation in amorphous metals. Due to the lack of long-range translational order, details of structural defects and their behaviors in metallic glasses have not been accessible in experiments. In addition, the small dimensions of the amorphous alloys made early by rapid quenching impose severe limit on many standard mechanical and microscopy testing. As a result, the micro… more

Numerical and Physical Modelling of Bubbly Flow Phenomena - Final Report to the Department of Energy

Description: This report describes the main features of the results obtained in the course of this project. A new approach to the systematic development of closure relations for the averaged equations of disperse multiphase flow is outlined. The focus of the project is on spatially non-uniform systems and several aspects in which such systems differ from uniform ones are described. Then, the procedure used in deriving the closure relations is given and some explicit results shown. The report also contains a… more

Progress Report for the grant "Hight-Resolution Mineralogical Charaterization and Biogeochemical Modeling of Uranium Reduction Pathways at the NABIR Field-Research Center"

Description: We have successfully completed a proof-of-concept, one-year grant on a three-year proposal from the former NABIR program. Using a state-of-the-art 300-kV, atomic resolution, Field Emission Gun Transmission Electron Microscope (TEM), we have successfully identified three categories of mineral hosts for uranium in contaminated soils from the Oak Ridge FRC: (1) iron oxides: (2) mixed manganese-iron oxides; and (3) uranium phosphates.
