The on-going annual increase in global methane (CH4) emissions can be largely attributed to anthropogenic activities. However, as more than half of these emissions are diffuse and possess a concentration less than 3% (v/v), physical-chemical treatments are inefficient as an abatement technology.

Soluble methane monooxygenase: activation of dioxygen and methane
Current Opinion in Chemical Biology, 2002The mechanisms by which soluble methane monooxygenase uses dioxygen to convert methane selectively to methanol have come into sharp focus. Diverse techniques have clarified subtle details about each step in the reaction, from binding and activating dioxygen, to hydroxylation of alkanes and other substrates, to the electron transfer events required to ...

Journal of the Air Pollution Control Association, 1967
Methane is present in the troposphere with a volume concentration of about 1.5 ppm. Estimates of Koyama indicate a predominantly biological origin with a total production rate of about 2.7 x 10/sup 14/ g CH/sub 4//yr. From that the author estimated the atmospheric lifetime of methane to be around 20 years.

Mechanistic Studies on the Hydroxylation of Methane by Methane Monooxygenase
Chemical Reviews, 2003Methanotrophs are bacteria that live on methane as their only source of carbon.1 The first step in their utilization of this simplest of all hydrocarbons is its selective conversion to methanol. Subsequent biochemical pathways transform methanol to formaldehyde, which in turn is processed into biomass.

Rotational spectra of methane and deuterated methane in helium
The Journal of Chemical Physics, 2010We present calculations of the rotational excitations of CH4 and CD4 in helium using correlated basis function theory for excited states of spherical top molecules, together with ground state helium density distributions computed by diffusion Monte Carlo simulations.

Methane Monooxygenase: Functionalizing Methane at Iron and Copper
2014Methane monooxygenases (MMOs) catalyze the conversion of methane to methanol as the first committed step in the assimilation of this hydrocarbon into biomass and energy by methanotrophs, thus playing a significant role in the biogeochemistry of this potent greenhouse gas.

Methane combustion in hydrate systems: Water-methane and water-methane-isopropanol
Journal of Engineering Thermophysics, 2013Kinetics of dissociation of synthetic and natural methane gas hydrates, and also double isopropanol-methane hydrate is investigated. Thermal fields of the sample surfaces are measured by means of thermal imaging in combustion of released methane with clathrate dissociation.

Dissolved Methane Sensor for Methane Leakage Monitoring in Methane Hydrate Production
OCEANS 2006, 2006This paper describes the development of a dissolved methane sensor that will be used for the methane leakage monitoring in the methane hydrate production in Japan in the future. As for the requirements for the sensor, continuous, long-time use in a great water depth, real-time measurement, and outstanding response to the change of dissolved methane ...
