Supercritical Carbon Dioxie; An Efficient Solvent for Herbal Extraction

open access: yesJournal of Medicinal Plants, 2017
Supercritical fluid extraction (SFE) is an alternative to liquid extraction using solvents. Supercritical fluids can have solvating powers similar to organic solvents, but with higher diffusivities, lower viscosity, and lower surface tension.

Oxygen-isotope and trace element constraints on the origins of silica-rich melts in the subarc mantle [PDF]

open access: yes, 2007
Peridotitic xenoliths in basaltic andesites from Batan island in the Luzon arc contain silica-rich (broadly dacitic) hydrous melt inclusions that were likely trapped when these rocks were within the upper mantle wedge underlying the arc.
