Statement of Purpose: The inflammatory response plays a central role in bone repair and regeneration. Macrophages, the primary cells of the immune system, are major contributors to this process. Though originally believed to serve as only destructive, proinflammatory phagocytes, it is now recognized that macrophages display high plasticity and exist on a spectrum of phenotypes. We have shown th...
The nanoscale microstructure and chemistry of a transparent gahnite glass-ceramic its precursor glass were investigated using atom probe tomography, transmission electron microscopy, nuclear magnetic resonance spectroscopy. In the annealed glass, statistically significant ZrO clustering was observed along with Si depletion within 2 nm clusters. This is expected to be first step in nucleation cr...
We report results from an extensive study on the speciation of zinc (Zn) and its relation to the mobility and bioavailablity of this element in a smelter contaminated soil and an in situ remediated area of this soil 12 yr after the application of cyclonic ash and compost. Emphasis was placed on the role of neoformed precipitates in controlling Zn speciation, mobility and bioavailability under d...
