Abstract for Weekly Colloquium on December 1, 2016 at 4 pm in PAS 220

Recent technological advances and steadily increasing computational capabilities have led to a surge in the application of X-Ray Micro-Computed Tomography (mCT) in Earth and Environmental Sciences with objectives ranging from quantification of pore-scale interfacial dynamics and biofilm architecture to practical applications related to airborne particulates or enhanced oil recovery. The power of X-Ray CT for Earth and Environmental Science Research will be demonstrated based on a state-of-the-art benchtop mCT scanner with remarks to synchrotron mCT. Several potential applications will be illustrated. The crucial importance of X-Ray mCT data segmentation for subsequent morphometric analysis or fluid dynamics modeling will be discussed.
