4D Imaging of Acid Leaching in Porous Carbonado Diamond

Description

Porous carbonado diamonds were imaged in 3D using X-ray computed tomography before and after every step in a sequential acid digestion procedure. The resulting scans were registered to one another and masked to eliminate all exterior voxels (e.g. air, bag, and container). These images were then used to understand the effects of different acids on the pore-filling minerals. We were also able to assess how the nature of pore-filling material can affect measurements of porosity.
