Multidimensional and time-lapse studies are transforming our understanding of dynamic processes across the fields of science. The ability to characterize a process rather than just a sample allows revealing the mechanisms and capturing the transient stages of the process. This is particularly relevant when studying evolving porous structures. These structures are non-equilibrium systems sustained by the transport of energy and matter through coupled physical and chemical processes. As a result, the process kinetics is linked to the evolution of the pore structure.

This is a cross disciplinary session that aims to attract work from a range of divisions, e.g. aqueous geochemistry, soil science, hydrological science, energy resources and the environment. We invite contributions from studies of a variety of dynamic processes including geo(bio)chemical and geomechanical. We especially encourage:

A) Experimental work using multidimensional characterisation techniques that use penetrating radiation, e.g. X-ray or neutrons, to study the evolution of porous media, e.g. tomography, scattering and diffraction.

B) Numerical simulations based on new conceptual models, phenomenological laws or machine learning that describe dynamic processes from molecular to macroscale. We look forward to new studies that contribute to understanding the essential links between rates, time and the properties of the pore structure.

C) Combination of experiments, numerical simulations and field observations

PICO gives you the opportunity to increase the impact of results from dynamic experiments by interactively present videos and multidimensional images that cannot be explained efficiently in poster and oral sessions.
