7 p, 1.4 MB First-principles molecular dynamics insight into Fe2+ complexes adsorbed on edge surfaces of clay min / Liu, Xiandong (Nanjing University. State Key Laboratory for Mineral Deposits Research) ; Meijer, Evert Jan (University of Amsterdam. Amsterdam Centre for Multiscale Modelling) ; Lu, Xiancai (Nanjing University. State Key Laboratory for Mineral Deposits Research) ; Wang, Rucheng (Nanjing University. State Key Laboratory for Mineral Deposits Research)
Using first-principles molecular-dynamics simulations, probable inner-sphere complexes of Fe adsorbed on the edge surfaces of clay minerals were investigated. Ferrous ions are important reductants in natural processes and their properties can be altered significantly by complexation on edge surfaces of clay minerals. [...]

15 p, 714.1 KB On the problems of total specific surface area and cation exchange capacity measurements in organic-rich sedimentary rocks / Derkowski, Arkadiusz (Polish Academy of Sciences. Institute of Geological Sciences) ; Bristow, Thomas F. (NASA. Ames Research Center)
The increasing exploration and exploitation of hydrocarbon resources hosted by oil and gas shales demands the correct measurement of certain properties of sedimentary rocks rich in organic matter (OM). [...]

11 p, 500.6 KB Conformational effects of adsorbed polymer on the swelling behavior of engineered clay minerals / Kim, Sungho (University of Tennessee. Department of Civil and Environmental Engineering) ; Motyka, Michael A. (Pennsylvania State University. Department of Engineering Science and Mechanics) ; Palomino, Angelica M. (University of Tennessee. Department of Civil and Environmental Engineering) ; Podraza, Nikolas J. (University of Toledo. Department of Physics and Astronomy)
The conformational behavior of polymers in clay-polymer nanocomposites (CPN) is not fully understood because of the many factors involved. The purpose of the present study was to investigate the conformational behavior of a polymer at the micro- and meso-scales in order to predict the behavior of tunable CPN. [...]

13 p, 1.7 MB The determinative role of the exchange cation and layer-charge density of smectite on aflatoxin adsorption / Deng, Youjun (Texas A and M University. Department of Soil and Crop Sciences) ; Liu, Lian (Texas A and M University. Department of Soil and Crop Sciences) ; Velázquez Barrientos, Ana Luisa (Texas A and M University. Department of Soil and Crop Sciences) ; Dixon, Joe B. (Texas A and M University. Department of Soil and Crop Sciences)
Using bentonites to adsorb aflatoxin is an effective method of minimizing the toxicity of aflatoxin to animals and humans. Early studies indicated a more than 10-fold difference in aflatoxin adsorption capacity among different bentonites. [...]

18 p, 2.9 MB Mineralogy of Egyptian bentonitic clays I : Discriminant function analysis / Agha, Mohamed (Fayoum University. Department of Geology) ; Ferrell, Ray E. (Louisiana State University. Department of Geology and Geophysics) ; Hart, George F. (Louisiana State University. Department of Geology and Geophysics)
The purpose of the present investigation was to apply a discriminant function analysis (DFA) to quantitative mineralogical data from 124 Paleogene and Neogene bentonitic clays from the northern Western Desert of Egypt in order to establish an objective procedure for grouping the samples at three distinctly recognizable, but partially overlapping, levels of classification.

6 p, 644.1 KB The dispersive effect of sodium hexametaphosphate on kaolinite in saline water / Ma, Mark (Commonwealth Scientific and Industrial Research Organisation)
Freshwater has become increasingly scarce in many countries. To reduce the consumption of freshwater, the use of saline water resources in industry could provide an opportunity to meet the challenge of water-supply sustainability. [...]

9 p, 791.5 KB Stereochemistry and molecular recognition on the surface of a smectite clay mineral / Yamagishi, Akihiko (Toho University. Department of Chemistry) ; Sato, Hisako (Ehime University. Department of Chemistry)
Attempts at optical resolution and asymmetric syntheses using smectite clay minerals are described. Use of the method was prompted by the discovery that the saturated adsorption of a tris(chelated) metal complex, [Ru(1,10-phenanthroline)], by Na-montmorillonite depended heavily on the stereochemical properties.

(Indiana University. Department of Geological Sciences) ; Brassell, Simon C. (Indiana University. Department of Geological Sciences)
Most previous studies of the kaolin deposits in the southeastern United States have focused on their mineralogy and petrology to understand better the depositional and diagenetic environments of the kaolins. [...]
