The Spitzer Spectroscopic Survey of S-type Stars [PDF]

open access: yes, 2012
S-type AGB stars are thought to be in the transitional phase between M-type and C-type AGB stars. Because of their peculiar chemical composition, one may expect a strong influence of the stellar C/O ratio on the molecular chemistry and the mineralogy of ...

Evaluation of the mechanical properties of acetic-cure silicone with the addition of magnesium silicate

open access: yesActa Scientiarum. Health Sciences, 2015
Current study evaluates the mechanical properties (tensile and tear strength) of an acetic-cure silicone with the addition of 10 or 20% vol. magnesium silicate. Magnesium silicate was added to the silicone at concentrations of 10 (MS-10) and 20% (MS-20)
