Easier access to X‐ray microtomography (μCT) facilities has provided much new insight
from high‐resolution imaging for various problems in porous media research. Pore space …

Contaminant hydrogeological processes occurring in porous media are typically not
amenable to direct observation. As a result, indirect measurements (eg, contaminant …

We report here on recent developments and advances in pore-scale X-ray tomographic
imaging of subsurface porous media. Our particular focus is on immiscible multi-phase fluid …

Miscible-displacement experiments are conducted with perfluorooctanoic acid (PFOA) to
determine the contribution of adsorption at the air–water interface to retention during …

The objective of this work was to determine the methods that produce the most
representative measurements and estimations of air-water interfacial area specifically for the …

The HYDRUS unsaturated flow and transport model was modified to simulate the effects of
non-linear air-water interfacial (AWI) adsorption, solution surface tension-induced flow, and …

Achieving a representative elementary volume (REV) has become a de facto criterion for
demonstrating the quality of CT measurements in porous media systems. However, the data …

The release and transport of linear perfluorocarboxylic acids (PFCA) within the vadose-zone
beneath per-and polyfluoroalkyl substance (PFAS)-and non-aqueous phase liquid (NAPL) …

In this work, the constitutive relationship between capillary pressure (Pc), saturation (Sw),
and fluid‐fluid interfacial area per volume (IFA) is characterized using computed …

We demonstrate the application of a high‐resolution X‐ray Computed Tomography (CT)
method to quantify water distribution in soil pores under successive reductive drying. We …
