Behavior of Hydroxide at the Water/Vapor Interface
Hydroxide and hydronium, which represent the ionic products of water autolysis, exhibit a peculiar surface behavior. While consensus has been established that the concentration of hydronium cations is enhanced at the surface with respect to the bulk, the affinity of hydroxide anions for the water/vapor interface has been a subject of an ongoing controversy. On the one hand, electrophoretic and ...
متن کاملTransient water vapor at Europa's south pole.
In November and December 2012, the Hubble Space Telescope (HST) imaged Europa's ultraviolet emissions in the search for vapor plume activity. We report statistically significant coincident surpluses of hydrogen Lyman-α and oxygen OI 130.4-nanometer emissions above the southern hemisphere in December 2012. These emissions were persistently found in the same area over the 7 hours of the observati...
متن کاملScandium effect on the luminescence of Er-Sc silicates prepared from multi-nanolayer films
Polycrystalline Er-Sc silicates (Er x Sc2-x Si2O7 and Er x Sc2-x SiO5) were fabricated using multilayer nanostructured films of Er2O3/SiO2/Sc2O3 deposited on SiO2/Si substrates by RF sputtering and thermal annealing at high temperature. The films were characterized by synchrotron radiation grazing incidence X-ray diffraction, cross-sectional transmission electron microscopy, energy-dispersive X...
متن کاملHot Corrosion Behavior of Magnesite – Chromite Refractories Used in Reverberatory Furnaces at Sarcheshmeh Copper Complex
Iran’s Sarcheshmeh copper industries with an annual production of 120,000 tones are the biggest of it’s kind in South Asia. The main method of production is pyrometallurgical matte making in two reverberatory furnaces which use direct–bond magnesite-chromite refractories supplied by German and Austrian companies. Following a recent major overhaul, bricks in contact with slag, matte and furnace ...
متن کاملHydrous Silicates and Water on Venus
We used thermochemical equilibrium calculations to predict Water vapor, present at 30–45 parts per million by volstabilities of pure rock-forming hydrous silicates on Venus’ ume (ppmv) in Venus’ subcloud atmosphere (Drossart surface as a function of elevation, atmospheric H2O and SO2 concentrations, and oxygen fugacity (fO2). About 50 different et al. 1993; Pollack et al. 1993; DeBergh et al. 1...
