Losing the ability to fly gave ancient penguins their unique locomotion style. But leaving the sky behind didn’t cause major changes in their brain structure, researchers from The University of T...
Effectiveness of polymers on improving the fluid loss of Bentonite used in geosynthetic clay liners
Effectiveness polymers improving fluid loss Bentonite used geosynthetic clay liners
2012/3/30
Geosynthetic clay liners (GCLs) are generally used in engineering projects due to their low hydraulic conductivity with water. The bentonite component contributes hydration-induced swelling and impart...

Improving swell index fluid loss methods compatibility testing Bentonites
2012/3/30
Geosynthetic clay liners (GCLs) are now a common feature of environmental lining systems in landfills, leach-heap pads, impoundments, irrigation canals and aesthetic ponds. The ASTM standard method (A...
Mechanisms and Crystal Chemistry of Oxidation in Annite: Resolving the Hydrogen-Loss and Vacancy Reactions
Annite Biotite Crystal Chemistry Differential Thermal Analysis Ferrioxyannite Gas Chromatography Mossbauer Spectroscopy
2011/12/5
Abstract: A synthetic octahedral-site-vacancy-free annite sample and its progressive oxidation, induced by heating in air, were studied by powder X-ray diffraction (pXRD), Mössbauer spectroscopy,...
Loss of iron to gold capsules in rock-melting experiments
Loss iron gold capsules rock-melting experiments
2012/4/1
Gold is used widely for capsules in high-temperature rock-melting studies because it is generally
thought to absorb negligible Fe from silicate samples. However, we observed significant losses of Fe
...
The capsule materials Au, Ag Pd , and Pt, were tested for permeability to C-H-O fluids in a
piston-cylinder apparatus at 10 kbar and 900(R)C1100?C. The capsules were embedded in boron ni-
tride. Aft...
Analytical Electron Microscopy in Clays and Other Phyllosilicates: Loss of Elements from a 90-nm Stationary Beam of 300-keV Electrons
Analytical Electron Microscopy Clay Minerals Diffusion Element Loss Low Temperature Phyllosilicates Sputtering Stationary Beam
2011/12/8
Abstract: Diffusion of alkali and low-atomic-number elements during the microbeam analysis of some silicates by analytical electron microscopy (AEM) has been known for some time. Our repeated analyses...
