We discuss in a thermodynamic, geologically empirical way the long-term nature of stable majority ices that could be present Kuiper Belt Object 2014 MU69 after its 4.6 Gyr residence EKB as cold classical object. Considering stability versus sublimation into vacuum for suite commonly found on comets, Centaurs, and KBOs at average ~40K sunlit surface temperature over Myr to Gyr, we find only 3 co...

the gas separation performance of commercial ceramic titania and hybrid silica (hybsi®) membranes was assessed using the gas permeation and permporometry methods. results indicated that the hybsi® membranes have a hybrid surface containing regions covered by a polymeric matrix and others with inorganic pores. these membranes have high h2 selectivity, which increases significantly with temperatu...
