Hydrogen Generation in an Ultramafic Rock with Micro-CT and SEM-BEX

Micro-CT images and SEM-BEX images during hydrogen generation in an ultramafic rock at 4 bar and 100C. Four micro-CT image packages (0, 8, 23, and 30 hours) at three processing steps (raw, filtered, and segmented). SEM images of the surface of pre and post grains at various magnifications. SEM-BEX images of the pre and post samples with various elements. SEM-BEX spectra of the 5 largest grains in the pre and post samples.
