Previous computations of low temperature Rosseland and Planck mean opacities from Alexander & Ferguson (1994b) are updated and expanded. The new computations include a more complete equation of state with more grain species and updated optical constants. Grains are now explicitly included in thermal equilibrium in the equation of state calculation, which allows for a much wider range of grain c...

Carbonated ultramafic rocks (i.e., ophicarbonates) form by peridotite serpentinization and carbonation at the seafloor. Their metamorphic evolution is linked to that of serpentinites, hence dating deformation metamorphism in ophicarbonates will add constraints P-T-t history subducted lithosphere. A potential, yet underexplored, suitable mineral for geochronology perovskite (CaTiO3). We present ...

High permittivity barium titanate zirconate (BTZ) is often used for dielectrics in commercial multilayer ceramic capacitors, actuators applications, and is a highly promising material for dynamic random access memory (DRAM) and microelectromechanical system (MEMS) applications due to its very stable, high insulating characteristic against voltage. Especially, the material is promising for envir...

The new spectroscopic classes, L and T, are defined by the role of dust clouds in their atmospheres, the former by their presence and the latter by their removal and near absence. Moreover, the M to L and L to T transitions are intimately tied to the condensation and character of silicate and iron grains, and the associated clouds play pivotal roles in the colors and spectra of such brown dwarf...
