The title compound, C(9)H(8)BrNO(2), which was synthesized by the condensation of 4-bromo-benzaldehyde with nitro-ethane, possesses a trans configuration. The dihedral angle between the benzene ring and the mean plane of the double bond is 7.31 (3)°. The crystal structure is stabilized by short inter-molecular Br⋯O contacts [3.168 (4) Å].

Introduction: The presence of ethane in liquidfilled lakes on Titan was confirmed by the Cassini Visible and Infrared Mapping Spectrometer (VIMS) in 2008, and has been investigated in further detail by the Cassini radar instrument [1,2]. Radar sounding, infrared absorption, and modeling suggest that the lakes are predominantly liquid methane and ethane, with trace amounts of propane, butane, ot...

Two tetradentate ligands 1,2-bis[2-((dimethylamino)methyl)-6-pyridyl]ethane (L1) and 1,2-bis[2-(N-piperidinomethyl)-6-pyridyl]ethane (L2) and a hexadentate ligand 1,2-bis(2-((methyl(pyridylmethyl)amino)methyl)-6-pyridyl)ethane (L3) were prepared as part of a series of new polypyridine ligands possessing a 1,2-bis(2-pyridyl)ethane common moiety. L1 and L2 form mononuclear Cu(II) complexes [Cu(L)...

Solid methane (CH(4)), ethane (C(2)H(6)), and ethylene (C(2)H(4)) ices (thickness: 120 ± 40 nm; 10 K), as well as high-density polyethylene (HDPE: [C(2)H(4)](n)) films (thickness: 130 ± 20 nm; 10, 100, and 300 K), were irradiated with mono-energetic oxygen ions (Φ ~ 6 × 10(15) cm(-2)) of a kinetic energy of 5 keV to simulate the exposure of Solar System hydrocarbon ices and aerospace polymers t...

The short-chain non-methane hydrocarbons (NMHC) are mostly emitted into the atmosphere by anthropogenic processes. Recent studies have pointed out a tight linkage between the atmospheric mole fractions of the NMHC ethane and the atmospheric growth rate of methane. Consequently, atmospheric NMHC are valuable indicators for tracking changes in anthropogenic emissions, photochemical ozone producti...

Marine hydrocarbon seeps supply oil and gas to microorganisms in sediments and overlying water. We used stable isotope probing (SIP) to identify aerobic bacteria oxidizing gaseous hydrocarbons in surface sediment from the Coal Oil Point seep field located offshore of Santa Barbara, California. After incubating sediment with (13)C-labeled methane, ethane, or propane, we confirmed the incorporati...

In this paper we present Ethane, a parallel search algorithm specifically designed for its execution on heterogeneous hardware environments. With Ethane we propose an algorithm inspired in the structure of the chemical compound of the same name, implementing a heterogeneous island model based in the structure of its chemical bonds. We also propose a schema for describing a family of parallel he...

The asymmetric unit of the title compound, C(12)H(12)N(2)·C(7)H(7)NO(2), contains two 3-amino-benzoic acid mol-ecules and two 1,2-bis-(4-pyrid-yl)ethane mol-ecules. In the two 1,2-bis-(4-pyrid-yl)ethane mol-ecules, the dihedral angles between the pyridyl rings are 2.99 (9) and 46.78 (8)°. In the crystal, the mol-ecules associate through amine and carboxyl group N-H⋯O=C inter-actions between one...

[1] Airborne whole air samples collected over the western Pacific in spring, 2001 showed depletion of tetrachloroethene (C2Cl4) in every upper tropospheric (UT) air parcel that had interacted with large areas of cirrus less than three days upwind. The amount of C2Cl4 depletion showed a negative correlation with time since the interaction, consistent with the C2Cl4-depleted air parcels mixing wi...

Different techniques for the measurement of lipid peroxidation in isolated hepatocytes have been compared. Measurements of ethane production, chemiluminescence and fluorescent products correlated extremely well with those of malondialdehyde formation. Of the five different techniques studied, measurements of ethane production and chemiluminescence were found to the the most sensitive indices of...
