Transport of Cryptosporidium Oocysts in Porous Media: Role of Straining and Physicochemical Filtration
TL;DR: The results of this study indicate that irregularity of sand grain shape contributes considerably to the straining potential of the porous medium, and both straining and physicochemical filtration are expected to control the removal of C. parvum oocysts in settings typical of riverbank filTration, soil infiltration, and slow sand filtrations.

Transport of MS2 Phage, Escherichia coli, Clostridium perfringens, Cryptosporidium parvum and Giardia intestinalis in a Gravel and a Sandy Soil •
TL;DR: In this paper, column experiments were conducted using natural soil and water from an infiltration site with fine sandy soil and a river bank infiltrate site with gravel soil to determine the removal of phages, bacteria, bacterial spores, and protozoan (oo)-cysts.

Role of grain-to-grain contacts on profiles of retained colloids in porous media in the presence of an energy barrier to deposition.
TL;DR: It is demonstrated that in the presence of an energy barrier to deposition, grain-to-grain contacts strongly influence colloid deposition and the spatial distribution of retained colloids in porous media, and it is proposed that the nonmonotonic profiles resulted from translation of surface-associated microspheres and subsequent immobilization at grain- to- grain contacts.

Pore-scale observation of microsphere deposition at grain-to-grain contacts over assemblage-scale porous media domains using X-ray microtomography.
TL;DR: The ability of filtration theory to predict the magnitude and spatial distribution of deposition demonstrates that filTration theory captures the essential elements of deposition in the absence of an energy barrier despite a lack of accounting for grain-to-grain contacts.

Asymmetric hydrovinylation of styrene applying cationic allyl palladium complexes of a P-chiral ligand
TL;DR: In this article, Cationic allyl palladium complexes of the diasteriomerically pure P-chiral ligand tert-butyl(menthyl-O)phenylphosphinite 1 and the complex [(η3-C3H5)PdI(1)] 9 were characterized by X-ray crystallography.
