  5. Pathways for Metastable Carbonate Synthesis

    Ff3655435?file=thumbnail
    Description: Carbonate minerals are integral to life on earth, as reservoirs for CO2 in the earth’s natural carbon cycle and as the skeletal elements of abundant organisms like corals and plankton. Because of its relevance, availability, and low toxicity, calcium carbonate is also an important model system for phase transformations in...

  7. Thermally Activated Self-lubricating Nanostructured Coating for Cutting Tool Applications

    6q182k30f?file=thumbnail
    Description: The different nitride phases of Cr and Mo were studied as possible candidates in a bi-layered system that would constitute a thermally activated self lubrication coating for dry cutting applications. The intent was to deposit multilayer films of CrN and Mo2N, where the Mo2N forms a sacrificial oxide that lubricates...

  8. Quantitative Analysis of Complex Three-Dimensional Microstructures

    Xd07gs84x?file=thumbnail
    Description: The morphological evolution due to coarsening is analyzed for two distinctive types of microstructure. First, the feasibility of characterizing spatial correlations of interfacial curvature in topologically complex structures is demonstrated with the analysis of bicontinuous two-phase mixtures produced using phase field modeling. For structures produced with both conserved and nonconserved...
