Spectroscopy Study of Arsenite [As(III)] Oxidation on Mn-Substituted Goethite
Arsenate Arsenite Mn-Substituted Goethite Oxidation XANES
2011/12/7
Abstract: Mn-substituted goethite was synthesized and the interaction between arsenite (As(III)) and Mn-substituted goethite was investigated by both solution chemistry and X-ray adsorption near edge ...
Equation of state of brucite: Single-crystal Brillouin spectroscopy study and polycrystalline pressure-volume-temperature measurement
Single-crystal Brillouin spectroscopy polycrystalline pressure-volume-temperature measurement
2012/3/30
Acoustic velocities of brucite were measured at room pressure in over 48 directions from Brillouin spectroscopy using a natural sample. These data are supplemented with volume measurements as a functi...

The coordination environment of Ti in eight Ti-bearing glasses of the Na Si-Na,Ti
y4 ;:join (NTS) and in six ATY2 glasses (A20Ti02.2Y02, with A =Na, K, ~r Rb andSi or Ge) was determined using high-re...
Infrared Spectroscopy Study of Tetrahedral and Octahedral Substitutions in an Interstratified Illite-Smectite Clay
Chourabi-Fripiat test Hofmann-Klemen effect Illite Infrared spectroscopy Interstratified Smectite Tetrahedral substitution
2011/12/28
Infrared spectroscopy is used to distinguish between octahedral and tetrahedral substitutions in an interstratified illite-smectite clay. The Hofmann-Klemen (Li) test suggests that the AlMg□ and FeMg□...
Structure-Composition Relationships in Trioctahedral Chlorites: A Vibrational Spectroscopy Study
Chlorite Hydroxyl Infrared spectroscopy Raman spectroscopy Structure
2012/1/4
Raman and Fourier-transformed infrared spectra of natural trioctahedral chlorites of polytype IIb were obtained for a series of samples characterized by distinct Fe/(Fe + Mg) and Si/Al ratios ranging,...
