Effects of Wet Grinding Process on the Properties of the Ground Diatomite Particles
Adsorption Diatomite Grinding Time Wet Grinding
2011/11/14
Wet grinding of diatomite was carried out in a stirred mill. The changes in particle size, specific surface area and structure or the particle shape in the wet grinding process were investigated. The ...
Mineralogical and chemical characterization of suspended atmospheric particles over the east Mediterranean based on synoptic-scale circulation patterns
Suspended desert dust Pollution Mineralogy
2011/11/11
Suspended atmospheric particles were collected in Israel in order to identify their nature and relationships with the major synoptic-scale circulation patterns. The particles were analyzed for their m...

Impact of Different Asbestos Species and other Mineral Particles on Pulmonary Pathogenesis
Asbestos Clays Lung Neutrophils Pathology Phagocytosis Physicochemical Silica Talc
2011/12/7
Abstract: Factors that are potentially important in the pulmonary pathogenesis of asbestos and other mineral particles are: 1) morphology, 2) Fe-content, 3) solubility under intra-phagosomal condition...
New insights into organic-mineral particles: composition, properties and models of molecular structure
Analytical pyrolysis Computational chemistry Molecular modelling Soil organic-mineral particles Xenobiotic complexes
2011/11/8
Organic-mineral soil particles are formed and altered as a result of pedogenic processes and anthropogenic impacts on soils. They can be isolated from
bulk soil samples by physical disaggregation fol...

Effect of Interaction Between Clay Particles and Fe3+ Ions on Colloidal Properties of Kaolinite Suspensions
Colloid Electron Microscopy Flocculation Iron Kaolinite Sedimentation Zeta Potential
2011/12/22
Abstract: Fine kaolinite suspensions were mixed with unaged or aged FeCl3 in this experiment. The interaction between clay particles and Fe3+ hydrolysis products was studied by transmission electron m...
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 ...
Size and Shape of Allophane Particles in Dispersed Aqueous Systems
Allophane Cluster Colloid Domain Light Scattering Shape Size Ultrafiltration Viscosity
2011/12/27
Abstract: Aqueous suspensions of allophane show relatively high viscosity, presumably because of strong particle interaction between the unit particles. To test this hypothesis, we measured the partic...
Separation of Sub-Micron Particles from Soils and Sediments without Mechanical Disturbance
Clays Dialysis Dispersion Mobility Particles Sediments Separation Size Soils Submicron Swelling
2011/12/1
Abstract: A method is described for the separation of the finest particles from soils and sediments without mechanical disturbance. Particles are separated through the induction of osmotic stress. Gen...
Crystallochemical Study of a Population of Particles in Smectites from a Lateritic Weathering Profile
Crystal-chemistry ESR FTIR Layer structural composition Mossbauer Nontronite Smectite Solid-solution
2011/12/31
In the copper deposit of Salobo 3A (Brazil), nontronite-like clay samples were found at the bottom of the weathering blanket. Samples were fractionated first by sedimentation and then by a HGMS method...
Characterization of Overgrowth Structures Formed Around Individual Clay Particles During Early Diagenesis
Beidellite Diagenesis Illite Montmorillonite Overgrowths Scanning electron microscopy
2012/1/10
The coarse (0.4? 祄) clay fraction of an Albian black shale collected in the Atlantic Ocean (Deep Sea Drilling Project leg 11) consists chiefly (90?5%) of smectite and 5?0% illite. Both minerals are lo...
Transmission Electron Microscope Data for Rectorite: Implications for the Origin and Structure of “Fundamental Particles”
“Fundamental particles” Illite Interstratification Lattice fringe images Rectorite Smectite Transmission electron microscopy
2012/1/11
Alternating mica-like and smectite-like layers of rectorite give rise to periodically varying contrast in 10-Å lattice fringes, yielding a periodicity of 20 Å in a transmission electron mi...
