Synchrotron based Transmission x-ray microscopy reveals smectite fine structure in an aqueous environment
Synchrotron Transmission x-ray microscopy reveals smectite fine structure aqueous environment
2012/3/30
The unusual behaviour of smectites, the ability to change volume when wetted (swelling) or dried (shrinking), make soil containing smectites very unstable and hazardous for the building industry due t...
In-situ chromium isotope measurement of chromium-rich fine grains in the Murchison CM2 chondrite
54-chromium isotopic anomaly presolar grain
2017/4/12
Isotopic anomalies of 54Cr have been reported in bulk chondrites. Stepwise dissolution experiments have suggested
the presence of a carrier of the 54Cr anomaly, probably of presolar origin. Although ...
Formation of a sandy near-bed transport layer from a fine-grained bed under oscillatory flow
sandy near-bed transport layer fine-grained bed oscillatory flow
2014/4/8
Bed surface coarsening was found to be an important effect for the formation of ripples and the dynamics of the boundary layer above a predominantly silt-sized sediment bed (median particle size equal...
Structural Chemistry of Fe, Mn, and Ni in Synthetic Hematites as Determined by Extended X-Ray Absorption Fine Structure Spectroscopy
EXAFS Fe Oxides Hematite Metal Substitution Trace Elements XAS XRD
2011/12/6
Abstract: The incorporation of transition metals into hematite may limit the aqueous concentration and bioavailabity of several important nutrients and toxic heavy metals. Before predicting how hemati...

Celadonite Glauconite Illite IR Spectra Leucophyllite OH Stretching Frequency
2011/12/9
Abstract: A large and representative collection of clay-size dioctahedral mica minerals differing in their chemical compositions has been studied by infrared (IR) spectroscopy in the OH stretching vib...
Effect of Salt on the Flocculation Behavior of Nano Particles in Oil Sands Fine Tailings
Fine Tailings Flocculation Gelation 2H NMR Nano Particles Oil Sands
2011/12/1
Abstract: Currently, two commercial plants, operating in the Athabasca region of Alberta, produce approximately 20 percent of Canada's petroleum requirements from oil sands. Surface mined oil sand is ...
Characterization of Colloidal Solids from Athabasca Fine Tails
Fine tails Hydrophilic Colloidal solids
2011/12/29
During processing of Athabasca oil sands, the finely divided solids form an aqueous suspension, which ultimately stabilizes as a gel-like structure retaining up to 90% of the process water. This gelli...
Sedimentation Behavior of a Fine Kaolinite in the Presence of Fresh Fe Electrolyte
Colloid Flocculation Iron Kaolinite Sedimentation
2011/12/31
The sedimentation behavior of a fine kaolinite, comprising a substantial proportion of colloidal particles as well as non-colloidal ones, has been studied when fresh FeCl3 or F2(SO4)3 electrolytes are...
Contributions of Forest Opal and Associated Crystalline Phases to Fine Silt Clay Fractions of Soils
Forest Opal Associated Crystalline Phases Silt Clay Fractions Soils
2012/2/15
The scanning electron microscope (SEM) is useful in the identification of biogenic opal. Opaline spheres, cups, and scrolled or convoluted sheets were identified in both soil and vegetative isolates. ...
