The Pliocene–Pleistocene Lake Tecopa beds present a well-documented example of authigenic silicate diagenesis in an ancient saline, alkaline lake environment. Controls on authigenic mineral formation ...
The dry sliding and friction behaviors of organoclay modified hydrogenated nitrile (HNBR) and ethylene/propylene/diene (EPDM) rubbers were studied using a pin (steel)-on-plate (rubber sheet) test conf...
The mechanical properties, heat aging resistance,dynamic properties, and abrasion resistance of fibrillar silicate (FS)/styrene butadiene rubber (SBR) nanocomposites are discussed in detail. Compared ...
The mineralogical and geochemical characteristics of Eocene continental sedimentsin south central Tunisia (Chebket Bouloufa and Jebel Hamri) and in north central Tunisia (Jebel Lessouda and Jebel Rhe磑...
The coordination environment of 20-200 ppm Pt in yellowish glasses from the CaO-Al O -SiO 2 3 2(CAS) ternary was studied using X-ray absorption fine structure spectroscopy at the Pt-L edge. IIIedge...

25Mg NMR spectra for several silicate and aluminosilicate melts were obtained from 1000–1470 8C. The peaks are initially very broad, but narrow with increasing temperature to near 500 Hz at the highes...
Experiments reported herein document heterogeneous crystal nucleation on bubbles in supercooled lithium disilicate melt. Crystalline lithium disilicate (Li2Si2O5) nucleated and grew on small bubb...
An atomistic computer simulation study was undertaken to address the role of Al in the substitution of ferric iron into magnesium silicate perovskite, MgSiO 3. Calculated substi-tution and vacancy en...
Crystals of sodium heptasilicate (Na8Si7O18) have been grown at 9 GPa, 1000 8 C using the MA6/8 superpress at Edmonton. The X-ray structure was determined at room pressure( R 5 5.8%). Sodium heptasili...
The effect of water (5 H2O 1 OH) on the environment of Co21and Ni21 in albite glass was investigated by electronic absorption spectroscopy. The visible spectra of Co21-doped glasses change only slight...
