The crystal structure of zektzerite, NaLiZrSi6O15, orthorhombic (space group Cmca), consists of six-tetrahedral-repeat corrugated double silicate chains connected into a three-dimensional framework by edge-sharing Li tetrahedral–Zr octahedral chain

International audience; We report on the lattice dynamics of MgSiO 3 perovskite (bridgmanite). Phonon spectroscopy was performed employing inelastic X-ray scattering from single crystals, and the results were confronted to ab initio calculations. We

In efforts to improve the thermal conductivity (TC) of Ultem(TM) 1000, it was compounded with three carbon based nano-fillers. Multiwalled carbon nanotubes (MWCNT), vapor grown carbon nanofibers (CNF) and expanded graphite (EG) were investigated. Rib

We have undertaken a detailed analysis of the X-ray photoelectron spectra obtained from the three polymorphs of Al2SiO5; andalusite, sillimanite, and kyanite. Comparison of the spectra was made based on the chemical bonding and structural differences

High-resolution single-crystal X-ray diffraction intensities recorded with a charge-coupled device detector at low temperature (100 K) were used to derive the electron density distribution in three Al2SiO5 polymorphs: andalusite, sillimanite, and kya

Enstatite ${\mathrm{Mg}}_{2}{\mathrm{Si}}_{2}{\mathrm{O}}_{6}$ is an important rock-forming silicate of the pyroxene group. It exists in several polymorphs, the structures of which are characterized by double $[{\mathrm{MgO}}_{6}]$ octahedral bands a

The crystal structure of the high temperature phase of KAlSi 2 O 6 at 700 dgC has been refined to R (%) = 5.4 by the least-squares method using 309 reflections. The thermal oscillation of K atom is great and the equivalent temperature factor B eq = 1
