In subsurface environments, incomplete mixing at the pore scale limits reaction rates,
rendering their prediction by Darcy‐scale models challenging. Such pore scale …

Biodegradation is an important mechanism of contaminant removal from soils. We use
numerical simulations to study the contaminant transport in heterogeneous soils subject to …

Polystyrene nanoplastics (PSNPs) when exposed to nanopermethrin (NPER) exacerbate
toxicity on Artemia salina. In the environment, NPs act as a vector for other pollutants mainly …

Biogeochemical reaction kinetics are generally established from batch reactors where
concentrations are uniform. In natural systems, many biogeochemical processes are …

Concentration fields of solutes in porous media often exhibit large fluctuations, driven by
physical and chemical heterogeneity from the pore to the Darcy scale. For many …

Water resource scarcity, food security, and environmental pollution are three major issues,
that threaten the sustainability of the natural environment and the lives and livelihoods of …

Les réactions chimiques souterraines jouent un rôle crucial dans la dynamique de la zone
critique. La cinétique des réactions chimique est généralement déterminée à partir …

We consider an enzyme-substrate reaction-diffusion problem. Unsteady and steady state
models are recalled. For the unsteady state case, the model is in the form of a second order …
