Hydrogen (H 2) is currently considered a clean fuel to decrease anthropogenic greenhouse
gas emissions and will play a vital role in climate change mitigation. Nevertheless, one of …

Carbon geosequestration (CGS) has been identified as a key technology to reduce
anthropogenic greenhouse gas emissions and thus significantly mitigate climate change. In …

Proton exchange membrane fuel cells, consuming hydrogen and oxygen to generate clean
electricity and water, suffer acute liquid water challenges. Accurate liquid water modelling is …

A significant amount of theoretical, numerical and observational work has been published
focused on various aspects of capillary trap** in CO 2 storage since the IPCC Special …

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 …

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 …

Newly developed high-speed, synchrotron-based X-ray computed microtomography
enabled us to directly image pore-scale displacement events in porous rock in real time …

Understanding the pore-scale dynamics of two-phase fluid flow in permeable media is
important in many processes such as water infiltration in soils, oil recovery, and geo …

Contact angle is a principal control of the flow of multiple fluid phases through porous media;
however its measurement on other than flat surfaces remains a challenge. A new method is …

A quantitative in situ characterization of the impact of surface roughness on wettability in
porous media is currently lacking. We use reservoir condition micrometer-resolution X-ray …
