Groundwater redox conditions and conductivity in a contaminant plume from geoelectrical investigations

Autor: V. Naudet, A. Revil, E. Rizzo, J.-Y. Bottero, P. Bégassat

Publikováno v: Hydrology and Earth System Sciences, Vol 8, Iss 1, Pp 8-22 (2004)

Accurate mapping of the electrical conductivity and of the redox potential of the groundwater is important in delineating the shape of a contaminant plume. A map of redox potential in an aquifer is indicative of biodegradation of organic matter and o

Evolution of Pb speciation in Portland cement during leaching

Autor: A. Benard, A. Vichot, D. Lemarchand, Jérôme Rose, A. Masion, J. Y. Bottero, J. L. Hazemann

Publikováno v: Journal de Physique IV (Proceedings). 107:143-146

Heavy metals, coming from raw materials and combustibles, are present in trace amount in cement. This study aims at evaluating Pb long-term behaviour, linking the evolution of Pb speciation due to leaching, with changes in the structure of the bearin

[Toxicity of nanoparticles on reproduction]

Autor: F, Greco, B, Courbière, J, Rose, T, Orsière, I, Sari-Minodier, J-Y, Bottero, M, Auffan, J, Perrin

Publikováno v: Gynecologie, obstetriquefertilite. 43(1)

Nanoparticles (NPs) are sized between 1 and 100nm. Their size allows new nanoscale properties of particular interest for industrial and scientific purpose. Over the past twenty years, nanotechnology conquered many areas of use (electronic, cosmetic,

Flocs Restructuring during Aggregation: Experimental Evidence and Numerical Simulation

Autor: Mark R. Wiesner, Stéphane Moustier, Antoine Thill, J. Y. Bottero, J. Aziz

Publikováno v: Journal of Colloid and Interface Science. 243:171-182

Aggregate structure, i.e., fractal dimension, has a coupled geometric and hydrodynamic impact on the aggregate collision frequencies. In this work, we evaluated different collision frequency kernel calculation schemes to simulate experimentally deter

NMR Evidence of Silicate and Carbonate Competition for Cations in Solution at Low Temperature: Case of Ca2+, Zn2+, Pb2+, and Al3+

Autor: S. Fraval, William E. E. Stone, P. Broekaert, Pascal Pirotte, F. Mosnier, Francis Masin, J. Y. Bottero

Publikováno v: Langmuir. 13:2550-2556

The characterization of solids obtained by mixing soluble silicates and carbonates with metal salts containing cations such as Zn2+, Pb2+, Ca2+, or Al3+ has been performed. X-ray diffraction, scanning electron microscopy, and high-resolution Si-29 an

Flocculation of Colloidal Silica with Hydrolyzed Aluminum: An 27Al Solid State NMR Investigation

Autor: P. Tekely, Bernard Humbert, L. S. Derrendinger, H. Suty, Bruno Lartiges, J. Y. Bottero

Publikováno v: Langmuir. 13:147-152

Flocculation of colloidal silica with aluminum fractal polymers was investigated by 27Al magic angle spinning and 29Si cross polarization magic angle spinning NMR as a function of aluminum concentration and pH. Aluminum flocculant species were prepar
