Saturn’s largest satellite, Titan, has a thick atmosphere dominated by nitrogen and methane. The dense orange-brown smog hiding the satellite’s surface is produced by photochemical reactions of methane, nitrogen and their dissociation products with solar ultraviolet, which lead primarily to the formation of ethane and heavier hydrocarbons. In the years prior to the exploration of Titan’s surfac...

Schizophrenia is a common and debilitating mental illness. The disorder is thought to be developmental in origin, with oxidative stress being implicated as possible pathophysiological mechanism. Breath alkanes provide a non-invasive means to assess oxidative stress, with ethane levels reportedly increased in medicated patients with schizophrenia. It is possible, however, that the psychotropic m...

The catalytic properties of the metal-organic framework Fe2(dobdc), containing open Fe(II) sites, include hydroxylation of phenol by pure Fe2(dobdc) and hydroxylation of ethane by its magnesium-diluted analogue, Fe0.1Mg1.9(dobdc). In earlier work, the latter reaction was proposed to occur through a redox mechanism involving the generation of an iron(IV)-oxo species, which is an intermediate tha...

Based on driving force for crystallization of one-component gas hydrate, in this report an expression for the supersaturation for crystallization of multicomponent gas hydrate is derived. Expressions for the supersaturation are obtained in isothermal and isobaric regimes. The results obtained are applied to the crystallization of hydrates of mixtures of methane plus ethane and can apply to ...

Microbial communities present in the Gulf of Mexico rapidly responded to the Deepwater Horizon oil spill. In deep water plumes, these communities were initially dominated by members of Oceanospirillales, Colwellia, and Cycloclasticus. None of these groups were abundant in surface oil slick samples, and Colwellia was much more abundant in oil-degrading enrichment cultures incubated at 4 °C than ...

Kinetic and isotopic studies showed that C-H bond activation in ethane by surfaces essentially saturated with lattice oxygens is the sole kinetically relevant step in ethane oxidation on Mo-V-NbOx mixed oxides. These conclusions are consistent with the dependence of oxidation rates on O2 and C2H6 pressures, with H/D exchange and kinetic isotope effects, and with the preferential initial incorpo...

Supercritical fluid extraction of all-E-lycopene from tomato industrial wastes (mixture of skins and seeds) was carried out in a semi-continuous flow apparatus using ethane as supercritical solvent. The effect of pressure, temperature, feed particle size, solvent superficial velocity and matrix initial composition was evaluated. Moreover, the yield of the extraction was compared with that obtai...

A new one-dimensional NiII coordination polymer of 1,3,5-tris-(imidazol-1-ylmeth-yl)benzene, namely catena-poly[[aqua-(sulfato-κO)hemi(μ-ethane-1,2-diol-κ2O:O')[μ3-1,3,5-tris-(1H-imidazol-1-ylmeth-yl)benzene-κ3N3,N3',N3'']nickel(II)] ethane-1,2-diol monosolvate monohydrate], {[Ni(SO4)(C18H18N6)(C2H6O2)0.5(H2O)]·C2H6O2·H2O} n , was synthesized and characterized by elemental analysis, IR spectros...

It has recently been argued that the barrier to rotation around the C C bond in ethane is not to be explained by the generally accepted picture of steric hindrance between vicinal C H bonds in the eclipsed conformation but is caused by more favorable orbital interaction in the staggered conformation. In that conformation the C H bonds at opposite ends of the molecule have an in-plane trans conf...

In the title compound, C(15)H(9)Br(2)Cl(2)FO, the dihedral angle between the two aromatic rings is 6.0 (1)°. The dibromo-ethane fragment of the propan-1-one unit is disordered over two positions, with occupancies of ca 0.83 and 0.17. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds, C-H⋯π inter-actions, and Br⋯Cl [3.505 (2) and 3.576 (6) Å] and Cl⋯F [3.176 (2) Å] shor...
