... space and pore-level fluid distribution determined by X-ray microcomputed tomography (micro-CT). Digital images of pore space (or pore-scale fluid distribution) are typically obtained as gray-level images that first need to be processed and segmented to obtain the binary images that uniquely represent...

... to mineralize the contaminants. A typical oxidant is permanganate, which generates carbon dioxide (CO 2 ) as gas and manganese oxides (MnO 2 ) as precipitates. In this study, microcomputed tomography (micro-CT) imaging has been used successfully to visualize the oxidation of diesel fuel with permanganate...
