Mineralogical evolution of a claystone after reaction with iron under thermal gradient / Jodin-Caumon, Marie-Camille (Université de Lorraine) ; Mosser-Ruck, Régine (Université de Lorraine) ; Randi, Aurélien (Université de Lorraine) ; Pierron, Olivier (Université de Lorraine) ; Cathelineau, Michel (Université de Lorraine) ; Michau, Nicolas (Agence nationale pour la gestion des déchets radioactifs)
The design of the repository for high-level nuclear waste (HLW) in France consists of a multiple-barrier system including steel canisters in a clay host rock. The system will undergo temperature variations in time and space, the heat source being the HLW within the canisters. [...]

Patterned deposition of allophane nanoparticles on silicon substrates / Fuchs, Marco (Karlsruhe Institute of Technology) ; Abidin, Zaenal (Bogor Agricultural University) ; Kübel, Christian (Karlsruhe Institute of Technology) ; Weidler, Peter G. (Karlsruhe Institute of Technology) ; Matsue, Naoto (Ehime University Tarumi) ; Henmi, Teruo (Ehime University Tarumi) ; Köster, Rainer (University of Regensburg. Institute of Analytical Chemistry) ; Gliemann, Hartmut (Karlsruhe Institute of Technology)
In order to obtain nanopatterned surfaces, natural allophane particles originating from Japanese soils were immobilized as single particles on Si wafer substrates. When derived from aqueous suspensions, only a few nanoparticles were deposited and detected on the surface due to the weak adsorption of allophanes on the substrate. [...]

Nitrate reduction by redox-activated, polydiallyldimethylammonium-exchanged ferruginous smectite / Su, Kai (Southwest Jiaotong University) ; Radian, Adi (Hebrew University of Jerusalem) ; Mishael, Yael (Hebrew University of Jerusalem) ; Yang, Lizhong (Southwest Jiaotong University) ; Stucki, Joseph W. (University of Illinois)
Nitrate is linked to chronic human illness and to a variety of environmental problems, and continues to be a contaminant of concern in soils and natural waters. Improved methods for nitrate abatement, thus, are still needed. [...]

The characterization of CaCO3 in a geothermal environment : A sem/tem-eels study / Kim, Jin-Wook (Yonsei University. Department of Earth System Sciences) ; Kogure, Toshihiro (University of Tokyo. Department of Earth and Planetary Science) ; Yang, Kiho (Yonsei University. Department of Earth System Sciences) ; Kim, Sang-Tae (McMaster University. School of Geography and Earth Sciences) ; Jang, Young-Nam (Korea Institute of Geoscience and Mineral Resources) ; Baik, Hion-Suck (Korea Basic Science Institute) ; Geesey, Gill (Montana State University. Department of Microbiology)
Mineralization of microbial biomass is a common phenomenon in geothermal habitats, but knowledge of the structure of the minerals formed in these environments is limited. A combination of spectroscopic, microscopic, and stable isotopic methods, as well as the chemical analysis of spring water, were employed in the present study to characterize calcium carbonate minerals deposited in filamentous cyanobacterial mats in different locations of La Duke hot spring, a circumneutral thermal feature near the north entrance of Yellowstone National Park, Montana, USA.

K-Ar age constraints on the origin of micaceous minerals in Savannah River Site soils, South Carolina, USA / Naumann, Thomas E. (Environmental Resources Management) ; Crawford Elliott, W. (Georgia State University. Department of Geosciences) ; Wampler, J. Marion (Georgia State University. Department of Geosciences)
K-Ar measurements were used in this study of upland Savannah River Site soils to distinguish between sorbed K and the K remaining in remnants of primary minerals. Study of sorbed K contributes to understanding further the interaction of alkali metals (Cs in particular) with the soils. [...]
