Several substances besides water ice have been detected on the surface of Europa by spectroscopic sensors, including CO 2 , SO 2 , and H 2 S. These substances might occur as pure crystalline ices, as vitreous mixtures, or as clathrate hydrate phases,

We have considered a wide array of scenarios for Europa's chemical evolution in an attempt to explain the presence of ice and hydrated materials on its surface and to understand the physical and chemical nature of any ocean that may lie below. We pos

We previously reported indirect but compelling evidence that fine-grained H2O ice under elevated CH4 gas pressure can persist to temperatures well above its ordinary melting point while slowly reacting to form methane clathrate hydrate. This phenomen

We report the discovery of the first high-pressure polymorphs of ammonia hydrates: ammonia monohydrate II and ammonia dihydrate II. The subsolidus transitions and melting curves of these substances are shown by their volume–temperature functions; u

Carbonaceons chondrites commonly contain 10-20% water-soluble salts by mass, the products of low-temperature aqueous alteration under oxidizing conditions. About 75% (by mass) of chondrite salts typically consists of magnesium sulfate hydrates. Condi

Measurements of self-diffusion coefficients to pressures of 2000 bar† 1 bar ≡ 105 N m-2. and densities to 2600 bar, except where limited by freezing, have been made for liquid hexafluorobenzene C6F6 at eight temperatures from 15°C to 150°C. The

Fluorine‐19 NMR has been studied from 105 to 4.2°K in elemental fluorine. In the liquid phase the spin–rotational interaction determines the spin–lattice relaxation time (T1) except within about 17°K of the melting point, where the effect of

Self‐diffusion coefficients and proton and deuteron relaxation times have been measured in cyclohexane (C6H12), cyclohexanone (C6H10O), and cyclohexanol (C6H12O). The results are interpreted with the quasilattice random flight (QLRF) model and a dy
