Oxidation State of Iron in Glauconite from Oxidized and Reduced Zones of Soil-Geologic Columns
Glauconite Iron Mossbauer spectroscopy Oxidized zone Pyrite Reduced zone Soil
2011/11/30
Abstract: Glauconite from the oxidized and reduced zones of soil-geologic columns at two Coastal Plain sites, one in Maryland and one in New Jersey, was examined by M鰏sbauer spectroscopy. The data ind...
Removal of radiocobalt from aqueous solution by oxidized MWCNT
Removal Co(II) Oxidized MWCNT Sorption
2011/11/11
The study was undertaken to evaluate the feasibility of oxidized multiwalled carbon nanotube (oxidized MWCNT) for the removal of radiocobalt (60Co) from aqueous solutions. The oxygen functional groups...

Distribution of cations vacancies atomic-resolution TEM image simulation
2012/4/1
The Fe, Mg, and vacancy distributions in oxidized olivine of intermediate composition and the crystal structures of associated planar defects were examined by a combination of atomic-resolution transm...
Acidified Oxalate and Dithionite Solubility and Color of Synthetic, Partially Oxidized Al-Magnetites and their Thermal Oxidation Products
Aluminum substitution Electron microscopy Hematite Maghemite Magnetite Oxidation Solubility
2011/12/1
Abstract: Submicron-sized (∼3–60 nm) powders of Al-substituted magnetite were synthesized in the laboratory by precipitation methods by mixing appropriate molar volumes FeCl2, FeCl3 and AlCl3 so...
Interpretation of Infrared Spectra of Oxidized and Reduced Nontronite
Oxidized Reduced Nontronite Interpretation structural hydroxyls
2012/2/13
Infrared spectra of nontronite reveal shifts to lower wave, number in peaks located at 3570, 1030, and 821 cm−1, which are assigned to vibrational modes for O-H stretching, Si-Ob (basal oxygens)...
