Properties of As and S at NiAs, NiS, and Fe1-xS surfaces, and reactivity of niccolite in air and water
NiAs NiS reactivity of niccolite air and water X-ray photoelectron spectroscopic
2012/3/31
Niccolite (NiAs), NiS (high temperature form), and pyrrhotite (Fe S) are structurally related,
with sulfur and arsenic sixfold coordinated. Their fracture or cleavage necessarily produces sur-
hybri...
Reactivity of Basal Surfaces, Steps and Edges of Muscovite: An AFM Study
AFM Morphology Muscovite Precipitation Reactivity Surfaces
2011/12/8
Abstract: The reactivity of basal surfaces, steps and edges of muscovite was studied by imaging surface precipitates of PbCl2 using atomic force microscopy (AFM). We reacted PbCl2 solution with freshl...
Studies of the Reactivity of the Ferrihydrite Surface by Iron Isotopic Exchange and Mossbauer Spectroscopy
Adsorption Arsenate Dissolution kinetics Ferrihydrite Iron octahedra Mossbauer spectroscopy Reactive sites Solubility Surface chemistry
2011/12/1
Abstract: Two-line ferrihydrite is an important adsorbent of many toxics in natural and anthropogenic systems; however, the specific structural sites responsible for the high adsorption capacity are n...
Hydrothermal Reactivity of Mixed-Layer Kaolinite/Smectite: Experimental Transformation of High-Charge to Low-Charge Smectite
Cation-exchange capacity Hydrothermal transformation Kaolinite/smectite Layer charge Smectite X-ray powder diffraction
2012/1/4
A mixed-layer kaolinite/smectite (K/S) containing trace amounts of quartz, discrete kaolinite, goethite-hematite, and calcite was hydrothermally reacted with deionized water at 150°, 200°, and 250°C f...
Reactivity of Anisoles on Clay and Pillared Clay Surfaces
Anisoles Bentonite Catalysis Fluorhectorite Montmorillonite Nuclear magnetic resonance Pillared clay Quinones
2012/1/4
Pillared bentonites were found to be efficient catalysts for the O-methyl bond cleavage of anisoles (e.g., m-methylanisole, guaiacol, and creosol) under very mild, static conditions (150亱C, a few hour...
