Cooperation is the key in the gas-phase formation of ethene by gold-dimer cations. As the cycle in the cover picture shows, two methane molecules are required to initiate the dehydrogenation step. A third methane molecule then cooperatively triggers the release of ethylene. The background shows...

(a) producing virtually no methane greenhouse gases through exhaling and eructation. The hydrogen by product of fermentation is instead converted into acetate, which is then used to provide further energy. The greenhouse gas effect of methane is 23 times greater than that of carbon dioxide. However...
Some of you may remember this scene at the very end ofStarfish— the moment when the chrysalis splits open and Lenie Clarke Mk 2 emerges to wreak vengeance on the world: A slender, translucent tentacle wraps softly around her wrist. It fades away into a distance utterly black to most, sl...
Greenhouse gases in the atmosphere, such as methane and carbon dioxide, trap some of the heat, keeping Earth’s climate warm and habitable. Without this process, Earth could not sustain life. However, the “man-made” greenhouse effect has now become a big problem. When people produce huge ...
aMany coalbed-methane prospects are under evaluation in the U.S. and throughout the world. In the U.S., higher gas prices have accelerated exploration of prospects in areas that previously were thought to be uneconomical for development. These areas include relatively unexplored new basins as we...
aIn the case of natural gas, 0.317 kmol of methane are consumed for the production of 1 kmol of H2. 在天然气情况下,甲烷0.317 kmol为H2 1 kmol的生产被消耗。[translate] athere are too many rules! 有许多规则![translate] abutterfly drop 蝴蝶下落[translate] ...
But the evils of farming don’t end there. The methane produced by cows is a major contributor to climate change. The run off from farms pollutes waterways where it kills wildlife. What you can do: Buy organic, free-range eggs and chickens. Buy your meat at farmer’s markets. Eat more...
Explanation: The methane mystery on Marsjust got stranger. New results from ESA and Roscosmos' ExoMars Trace GasOrbiter, has unexpectedly not detected methane in the atmosphere of Mars. Thisresult follows the 2013 detection of methane by NASA's Curiosity rover, aresult seemingly confirmed by ESA...
The chapter assesses the prospects for Arctic oil and gas development by taking a closer look at international determinants, which have been largely overlooked so far. These international factors include global market developments, geopolitical tensions
