Water enables mild oxidation of methane to methanol on gold single-atom catalysts
Nature Communications, 2021 As a 100% atom-economy process, direct oxidation of methane into methanol remains as a grand challenge due to the dilemma between activation of methane and over-oxidation of methanol.

Methane Cracking for Hydrogen Production: A Review of Catalytic and Molten Media Pyrolysis
Energies, 2021 Currently, hydrogen is mainly generated by steam methane reforming, with significant CO2 emissions, thus exacerbating the greenhouse effect. This environmental concern promotes methane cracking, which represents one of the most promising alternatives for

Experimental and modeling studies on continuous liquid removal in horizontal gas wells
Frontiers in Earth Science, 2023 The potential risks of liquid-loading can be significantly decreased by precisely calculating the minimum gas flowrate required for continuous liquid removal in gas wells and using suitable deliquification technology beforehand.

Methane, 2022 Methane pyrolysis can produce many valuable products besides hydrogen, e.g., C2 compounds or carbon black. In the conditions provided by microwave plasma, the distribution of these products might be shifted by the addition of hydrogen and nitrogen.

The Missing Link: Early Methane ("T") Dwarfs in the Sloan Digital Sky Survey [PDF]
Astrophys.J.536:L35-L38,2000, 2000 We report the discovery of three cool brown dwarfs which fall in the effective temperature gap between the latest L dwarfs currently known, with no methane absorption bands in the 1-2.5um range, and the previously known methane (T) dwarfs, whose spectra are dominated by methane and water.
