Quasielastic electron scattering from methane, methane-d4, methane-d2, ethylene, and 2-methylpropane.

Quasielastic electron scattering from gaseous species at high momentum transfer was recently reported for the first time [Cooper et al., J. Electron Spectrosc. Relat. Phenom. 155, 28 (2007)]. The first results for CH(4) and CD(4) were well explained by a classical electron Compton scattering picture in which the electron scatters independently from each atom rather than the molecule as a whole....

Methane in Kano-Nigeria atmosphere

ABSTRACT Methane concentrations in Kano municipality have been attributed to the burning of solid and fossil fuels and industrial processes. Using an automatic gas sampling system, methane in the Kano atmosphere was determined. Its distribution in the municipality was skewed towards high frequency of low concentration with a mean and standard deviation of 0.61? 0.39 ?g/m3. Similarly the distri...

Electron Compton scattering from methane and methane-d4

Quasi-elastic electron scattering at high-momentum transfer was measured for CH4 and CD4 in the gas phase. At high-momentum transfer, wo scattering peaks are observed in each molecule. We interpret the splitting as due to independent Compton scattering from each nucleus, such hat, at an impact energy of 2 keV and 100◦ scattering angle, the peaks for the C and H in CH4 are split by 2.1 eV while ...

Anaerobic methane oxidation and denitrification as methane sink

Early social exposure is important for developing appropriate, species-specific adult behaviors. Carson Murray et al. (pp. 18189–18194) followed wild chimpanzees, habituated to human observers, in Gombe National Park, Tanzania, and analyzed maternal subgrouping patterns to investigate why adult males tend to be more gregarious than adult females. Mothers accompanied by their sons were more greg...
