Coupling between diffusion and convection in radial dispersion of matter by fluid flow through packed beds
TLDR
In this paper, it was shown that coupling between diffusion and convection occurs not only in longitudinal dispersion of matter by fluid flow through packed beds, but also in radial dispersion.About:

Respiration and denitrification in permeable continental shelf deposits on the South Atlantic Bight: Rates of carbon and nitrogen cycling from sediment column experiments
TL;DR: In this paper, Nitrogen cycling and respiration rates were measured in sediment columns packed with southeastern United States continental shelf sands, with high permeability (4.66×10−11 m2) and low organic carbon (0.008%).

Breakthrough performance of high-capacity membrane adsorbers in protein chromatography
TL;DR: In this article, the performance of high capacity cation exchange membranes was studied and a dimensionless treatment of the breakthrough zone in frontal analysis led to the identification of a rate-limiting diffusive mechanism resulting from slow transport of proteins into the 3D adsorbing layer.

Hydrodynamics and performance in fluidized bed adsorption.
TL;DR: Axial mixing in the liquid phase of a classified fluidized bed based on porous glass granules is presented, showing a reduction of mixing at increased ratio of bed height to diameter as well as at increased linear velocity of the liquid stream.

Gas dispersion in packed beds

TL;DR: In this article, the authors measured dispersion coefficients from response curves measured using an ionisation detector situated in the gas stream and showed that at low Reynolds numbers ( = udpe/ν), the dispersion is effected by molecular diffusion, but at high Reynolds numbers eddy diffusion predominates.

TL;DR: These mechanisms are analysed on a statistical basis in terms of their basic variables and it is shown that various mechanisms may be combined by adding variances, diffusion coefficients or heights corresponding to a theoretical plate.

Dispersion of Soluble Matter in Flow through Granular Media
TL;DR: In this paper, the problem of dispersion of soluble matter within a one dimensional tube filled with granular media was treated, where the solvent is flowing slowly through the tube with mean velocity v, and it was desired to find the future concentration pattern of the soluble matter.
