Ž . Ž . Vibrational lifetime T data for the asymmetric CO stretching mode of W CO in supercritical ethane and carbon 1 6 w x dioxide as a function of temperature at various fixed densities are compared to a recent extended hydrodynamic theory 1 . In ethane at the critical density, as the temperature is raised, T initially becomes longer, reaching a maximum ;70 K above 1 the critical temperature...

The kinetics of film growth of hydrates of methane, ethane, and methane-ethane mixtures were studied by exposing a single gas bubble to water. The morphologies, lateral growth rates, and thicknesses of the hydrate films were measured for various gas compositions and degrees of subcooling. A variety of hydrate film textures was revealed. The kinetics of two-dimensional film growth was inferred f...

Considering that natural gas is the key transition fuel towards carbon-neutral future, objective of present study to gain insight into evolution features gas-diesel dual during ignition process. Firstly, new experimental data delay times for stoichiometric methane/ethane/propane-n-heptane mixtures, which significance validating and optimizing chemical kinetic models at engine-relevant condition...

Pulsed field gradient (PFG) NMR at high magnetic is used to study molecular self-diffusion of ethylene, ethane, and propylene in a 2-ethylimidazole (eIm) linker-doped ZIF-8. These eIm-doped materials were synthesized by incorporating increasing fractions the non-native eIm linker, which substitutes native 2-methylimidazole linker ZIF-8 framework. Self-diffusion three hydrocarbon gases was measu...

Using synchrotron X-ray powder diffraction, the structure of a co-crystal between benzene and ethane formed in situ at cryogenic conditions has been determined, and validated using dispersion-corrected density functional theory calculations. The structure comprises a lattice of benzene molecules hosting ethane molecules within channels. Similarity between the intermolecular interactions found i...

Laminar flame speeds of mixtures of ethane, ethylene, acetylene, and carbon monoxide with small amounts of hydrogen addition at both atmospheric and elevated pressures were experimentally and computationally determined. It was found that the approximate linear correlation identified previously between the laminar flame speeds and an appropriate definition of the amount of hydrogen addition for ...

Concentrations and isotopic compositions of ethane and propane in cold, deeply buried sediments from the southeastern Pacific are best explained by microbial production of these gases in situ. Reduction of acetate to ethane provides one feasible mechanism. Propane is enriched in (13)C relative to ethane. The amount is consistent with derivation of the third C from inorganic carbon dissolved in ...

The selective partial oxidation of short chain alkanes is a key challenge within catalysis research. Direct ethane oxidation to oxygenates is a difficult aim, but potentially rewarding, and it could lead to a paradigm shift in the supply chain of several bulk chemicals. Unfortunately, low C–H bond reactivity and kinetically labile products are just some reasons affecting the development and com...

Herbicide, Diphenyl Ether, Peroxidation, Antioxidants Measurements of ethane and ethylene as indices o f in vivo lipid peroxidation and o f chemicallyinduced stress, respectively, were done on mustard seedlings (Sinapis alba), treated with oxyfluorfen[2-chloro-l-(3-ethoxy-4-nitrophenoxy)-4-(trifluoromethyl)benzene]. When seedlings were exposed to low light intensity o f 14 W /m 2, only stress-e...

UNLABELLED PREMISE OF THE STUDY In spaceflight experiments, tissues for morphologic study are fixed in 3% glutaraldehyde, while tissues for molecular study are fixed in RNAlater; thus, an experiment containing both study components requires multiple fixation strategies. The possibility of using RNAlater-fixed materials for standard SEM-based morphometric investigation was explored to expand ...
