We report new molecular dynamics results elucidating the structure of the electrical double
layer (EDL) on smectite surfaces contacting mixed NaCl–CaCl 2 electrolyte solutions in the …

Diffusion of 36Cl− in compacted bentonite was studied using through-diffusion, out-diffusion
and profile analysis techniques. Both the bulk dry density of the bentonite and the …

Two sediment cores retrieved at the northern slope of Sakhalin Island, Sea of Okhotsk, were
analyzed for biogenic opal, organic carbon, carbonate, sulfur, major element concentrations …

Despite the importance of Fe redox cycling in clay minerals, the mechanism and location of
electron transfer remain unclear. More specifically, there is some controversy whether …

The mobility and availability of the toxic metalloid selenium in the environment are largely
controlled by sorption and redox reactions, which may proceed at temporal scales similar to …

The structure and mechanism of cation sorption at the (001) muscovite-water interface were
investigated in 0.01 and 0.5 m KCl, CsCl, and CaCl2 and 0.01 m BaCl2 solutions at slightly …

The long-lived radionuclide 79Se is one of the elements of concern for the safe storage of
high-level nuclear waste, since clay minerals in engineered barriers and natural aquifer …

Zn-Ti layered double hydroxide/montmorillonite (ZTL/MT) and Fe-doped ZTL/MT (ZTL/Fe@
MT20%) were prepared as photocatalyst for Cr (VI) reduction. The ZTL/Fe@ MT20 …

Electron donor amendment for bioremediation often results in precipitation of secondary
minerals and the growth of biomass, both of which can potentially change flow paths and the …

Experiments were performed herein to investigate the rates and products of heterogeneous
reduction of Tc (VII) by Fe (II) adsorbed to hematite and goethite, and by Fe (II) associated …
