Spontaneous filament formation and network self-assembly via active phase separation

We introduce Active Model H$^{-}$, a scalar phase-field model of non-equilibrium phase separation in the overdamped hydrodynamic limit, and show that it produces filamentous networks with enhanced connections and arrested coarsening, a morphology not observed in existing scalar active field theories. Isolated filaments...

Extracting microstructural descriptors from diffraction contrast x-ray tomography for grain growth modeling

Three-dimensional polycrystalline microstructure datasets from non-destructive x-ray characterization techniques such as diffraction contrast tomography (DCT) and high-energy diffraction microscopy (HEDM) encode rich information about grain boundary geometry, crystallography, and topology. Translating this into a reduc...
