Exploration and Management of Non-Equilibrium Experiments: Leveraging ExPetDB

ExPetDB is essential for non-equilibrium experiments, facilitating collaborative exchange, repurposing, and workflow management. With NSF requirements in mind, appropriate metadata is crucial, including starting material details, container type, quench rate, and variations in T, P, X, fO2. Unique to non-equilibrium experiments, data management requires spatial context, EDS/WDS maps, and EBSD context like BSE images and raw data. Building on the PetDB schema provides structure for effective data organization and retrieval.

  1. We have LEPR… why do we need ExPetDB?

  2. Non-equil. experiments need a home • Collaborative exchange • Repurposing* • Workflow management • NSF requirements • *appropriate metadata essential

  3. Example metadata • starting material, type and preparation • container material • fO2 (intended, actual) • apparatus • quench rate • variations in T, P, X, fO2* • objective* • *unique to non-equilibrium experiments

  4. Data management needs Spatial context

  5. Data management needs Spatial context Data “cubes” EDS/WDS maps

  6. Data management needs Spatial context Data “cubes” EDS/WDS maps EBSD Context: BSE image Raw data: EBSPs (104-105) Derived data: orientation maps, pole figures
