The surface structure of a-Fe2O3 (001) by scanning tunneling microscopy: Implications for interfacial electron transfer reactions
surface structure scanning tunneling microscopy interfacial electron transfer reactions
2012/3/31
STM images of hematite (?-Fe O ) (001) surfaces taken under a wider variety of conditions than in
previous studies are presented. The results strongly suggest that only Fe sites contribute to the tun...
K Transfer During Burial Diagenesis in the Mahakam Delta Basin (Kalimantan, Indonesia)
Diagenesis Illitization K transfer
2011/12/23
Abstract: Progressively buried sandstones and shales of the Mahakam Delta Basin in Indonesia were studied. Mineralogical, morphological and K-Ar isotopic data were obtained for clay, mica and feldspar...
Electron Transfer Processes Between Hydroquinone and Iron Oxides
Electron spin resonance Electron transfer Ferrihydrite Goethite Hematite Hydroquinone Iron
2012/1/9
The kinetics of hydroquinone oxidation by aqueous suspensions of pure hematite and goethite-ferrihydrite mixtures at pH 6.0, 7.4, and 9 was studied using an on-line analysis system. The electron trans...
Electron Transfer Processes Between Hydroquinone and Hausmannite (Mn3O4)
Electron spin resonance Electron transfer Hausmannite Hydroquinone Manganese Oxidation
2012/1/9
A kinetic study of the oxidation of hydroquinone by aqueous suspensions of hausmannite at pH 6 was conducted using an on-line analysis system. Electron transfer between hydroquinone and the oxide was ...
Intervalence Electron Transfer and Magnetic Exchange in Reduced Nontronite
Intervalence electron transfer Iron Magnetic susceptibility Nontronite Reduction UV-visible spectroscopy
2012/1/11
The effects of chemical reduction of structural Fe3+ in nontronite SWa-1 (ferruginous smectite) on intervalence electron transfer (IT) and magnetic exchange were investigated. Visible absorption spect...
