The stability of staurolite and chloritoid and their significance in metamorphism of pelitic rocks

TL;DR: In this paper, the reaction chlorite+muscovite=staurolite+biotite+quartz+vapor has been experimentally determined and reversible equilibrium has been demonstrated.
Journal ArticleDOI

Raman spectroscopy of calcium aluminate glasses and crystals

TL;DR: In this paper, a structural model is proposed which would be consistent with the glass spectra and with observed crystal structures along the CaAl2O4 ǫ-Al 2O3 join.
Journal ArticleDOI

Matrix phyllosilicates and associated minerals in C2M carbonaceous chondrites

TL;DR: TEM, HRTEM and HVEM methods coupled with energy dispersive X-ray analysis have been used to study the microstructure and the phases comprising the matrix of carbonaceous chondrites Murchison, Cold Bokkeveld, Nawapali and Cochabamba as mentioned in this paper.
Journal ArticleDOI

The structures and vibrational spectra of crystals and glasses in the silica-alumina system

TL;DR: In this paper, a structural model for the silica-alumina glass system is proposed, which is consistent with the stable or metastable immiscibility suggested along this join, and the essential features of this model include a modified silica structure at low alumina content, and structure-broken regions at high alumina compositions, with silicon in tetrahedral coordination, but aluminium assuming a variety of bonding geometries.

Exponential growth of LBL films with incorporated inorganic sheets.

TL;DR: It is demonstrated that e-LBL for inorganic sheets is possible in a complex tricomponent film of poly(ethyleneimine) (PEI), poly(acrylic acid) (PAA), and Na(+)-montmorillonite (MTM) with large thickness and rapid growth, which suggests fast permeation/reptation of polyelectrolytes between the nanosheets during the "in-and-out" diffusion of polymer.
