From the homeostasis of human health to the cycling of Earth's elements, microbial activities
underlie environmental, medical and industrial processes. These activities occur in chemical …

This review provides an overview of concepts and approaches for the quantification of
passive, non-reactive solute mixing in steady uniform porous media flows across scales …

Bacteria in porous media, such as soils, aquifers, and filters, often form surface-attached
communities known as biofilms. Biofilms are affected by fluid flow through the porous …

Essentially all hydrogeological processes are strongly influenced by the subsurface spatial
heterogeneity and the temporal variation of environmental conditions, hydraulic properties …

Using index matching and particle tracking, we measure the three-dimensional velocity field
in an isotropic porous medium composed of randomly packed solid spheres. This high …

Solute transport in unsaturated porous materials is a complex process, which exhibits some
distinct features differentiating it from transport under saturated conditions. These features …

Mixing-driven reactions in porous media are ubiquitous and span natural and engineered
environments, yet predicting where and how quickly reactions occur is immensely …

Dynamics of flowing air in partially water‐saturated, porous geological formations are
governed by a wide range of forces and parameters. These dynamics are reviewed in the …

The interplay between mixing and reactive processes plays a pivotal role in a range of
biogeochemical processes controlling the transport, transformation and turnover of chemical …

The functioning of natural and engineered porous media, like soils and filters, depends in
many cases on the interplay between biochemical processes and hydrodynamics. In such …
