TL;DR: In this paper, a simple method for determining diffusion coefficients of dense gases in liquids using a PVT cell was presented, which can be easily applied to multicomponent systems for measurement of effective diffusion coefficients in reservoir fluids.

TL;DR: The ability of Pycnoporus sanguineus to adsorb heavy metals from aqueous solution was investigated in fixed-bed column studies and the removal efficiency after adsorption-desorption studies was evaluated.

TL;DR: The two major models of the mechanism of mass and heat transfer are the film theory and penetration theory; these are not unrelated concepts, but are limiting cases of a more general model as mentioned in this paper.
Abstract: The two major models of the mechanism of mass and heat transfer betwoeen two phases are the film theory and penetration theory; these are not unrelated concepts, but are limiting cases of a more general model. Ouantitative transfer to old, intermediate, and young elements is dis cussed, along with mathematical development and curves. (J.R.D.)

TL;DR: In this paper, a model for evaporation as a molecular diffusion process into a turbulent atmosphere is extended by joining it with the similarity models for turbulent transfer in the surface sublayer.
Abstract: A model proposed earlier (Brutsaert, 1965) for evaporation as a molecular diffusion process into a turbulent atmosphere is extended by joining it with the similarity models for turbulent transfer in the surface sublayer. The assumed mechanisms were suggested by available flow visualization studies near smooth and rough walls; the theoretical result is in good agreement with available experimental evidence. The important dimensionless parameters governing the phenomenon near the surface are the Dalton (or Stanton) number (i.e., mass transfer coefficient), the drag coefficient (u*2/U2), the roughness Reynolds number (u*z0/v) (except for smooth surfaces), and the Schmidt (or Prandtl) number (v/k). The proposed formulation allows the evaluation of the effects of some parameters, such as surface roughness or molecular diffusivity, that were hitherto not well understood. An important practical result is that in contrast to the drag coefficient, the Dalton number is relatively insensitive to changes in roughness length Z0.

TL;DR: In this article, the authors explored the mass transfer mechanism for SO2 diffusion through gas filled pores by simple measurements in order to identify suitable membrane structures for use in contactors for flue gas cleaning.
