Reactive force field for lithium-aluminum silicates with applications to eucryptite phases [PDF]

open access: yesModelling Simul. Mater. Sci. Eng. 20 (2012) 015002, 2011
We have parameterized a reactive force field (ReaxFF) for lithium aluminum silicates using density functional theory (DFT) calculations of structural properties of a number of bulk phase oxides, silicates, and aluminates, as well as of several representative clusters.

New insights into the dust formation of oxygen-rich AGB stars [PDF]

open access: yes, 2013
We observed the AGB stars S Ori, GX Mon and R Cnc with the MIDI instrument at the VLTI. We compared the data to radiative transfer models of the dust shells, where the central stellar intensity profiles were described by dust-free dynamic model atmospheres. We used Al2O3 and warm silicate grains.

Environment of titanium and aluminum in a magnesium alumino-silicate glass [PDF]

open access: greenJournal of Physics: Condensed Matter, 2009
The structure of the glass 2MgO-2Al(2)O(3)-5SiO(2)-TiO(2) was investigated using neutron diffraction with isotopic substitution. Reverse Monte Carlo (RMC) modeling was used to reproduce experimental structure factors derived from diffraction experiments.

Mineral Processing by Short Circuits in Protoplanetary Disks [PDF]

open access: yesThe Astrophysical Journal Letters, Volume 767, Issue 1, article id. L2, 6 pp. (2013), 2013
Meteoritic chondrules were formed in the early solar system by brief heating of silicate dust to melting temperatures. Some highly refractory grains (Type B calcium-aluminum-rich inclusions, CAIs) also show signs of transient heating. A similar process may occur in other protoplanetary disks, as evidenced by observations of spectra characteristic of ...
