Close to a thousand presolar silicate grains have been identified since their initial discovery in interplanetary dust particles (IDPs) just over ten years ago. Studies have shown that silicates are ...
We present analytical protocols and the analytical performance of Pb isotope analysis of silicate minerals and rocks at the Pb = 0.02–15 ppm level using excimer laser ablation (LA) coupled with an en...
The distribution of tin between different granitic silicate melts and coexisting aqueous fluids have been determined at 850°C, 100 MPa and fO2 near NNO. Tin distribution coefficients are constrained ...
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...

The expansivity of a silicate melt in the relaxed liquid state was obtained by direct dilatometric measurement for the first time. During the measurement, the liquid sample resides within a metal co...

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...
