Using Silicate Mineral Particles for pH Control during in situ Bioremediation of Chlorinated Ethene Source Zones

Elsa Marina Lacroix

Soil and groundwater pollution by chlorinated solvents such as tricholorethene (TCE) and tetrachloroethene (PCE) is a frequent problem in the industrialized world. Chlorinated solvents, characterized by a low solubility and a density greater than water, fo ...

Water adsorption on a sodium smectite clay surface: an ab initio study

John Christopher Plummer, Pascal Clausen

Using calculations based on density-functional theory, we explore the configurations that water molecules (2,3,4;6) assume on the surface a sodium 2:1 smectite clay with isomorphic substitutions both on octahedral and tetrahedral sheets. The hydrophilicity ...

Adsorption of low-molecular-weight molecules on the surface of a sodium smectite clay: an ab initio study

John Christopher Plummer, Wanda Andreoni, Pascal Clausen, Alessandro Curioni

We present a study of the adsorption of single molecules of volatiles, such as water, ethanol, ethyl acetate, pyridine, toluene, and n-octane, on the dry surface of a smectite clay using a series of calculations based on density functional theory. Our clay ...

Subsolidus phase equilibria in the RuO2 - Bi2O3 - SiO2 system

Thomas Maeder

Subsolidus equilibria in the RuO2–Bi2O3–SiO2 diagram were studied with the aim of investigating possible interactions between the bismuth-ruthenate- based conductive phase and the silica-rich glasses in thick-film resistors. The tie lines are between Bi2Ru ...

Composites and methods for their production

Jan-Anders Edvin Maansson, Yves Leterrier, John Christopher Plummer, Marlene Rodlert

Intercalates and exfoliates formed from layered materials and dendritic polymers are disclosed, together with the uses of these materials, e.g. in producing composite materials. The dispersion of layered materials in a dendritic polymer matrix (hyperbranch ...
