Direct methane conversion to methanol by ionic liquid-dissolved platinum catalysts [PDF]
, 2006 Ternary systems of inorganic Pt salts and oxides, ionic liquids and concentrated sulfuric acid are effective at catalyzing the direct, selective oxidation of methane to methanol and appear to be more water tolerant than the Catalytica ...

Biotechnological aspects of sulfate reduction with methane as electron donor [PDF]
, 2010 Biological sulfate reduction can be used for the removal and recovery of oxidized sulfur compounds and metals from waste streams. However, the costs of conventional electron donors, like hydrogen and ethanol, limit the application possibilities.

Chemical looping dry reforming of methane using mixed oxides of iron and cerium: Operation window
Catalysis Communications, 2021 A series of the mixed oxides of iron and cerium, with an iron(III) oxide content ranging from 0 wt% to 100 wt% were tested as oxygen carriers in the chemical looping dry reforming of methane (CL-DRM).

Methane formation and methane oxidation by methanogenic bacteria [PDF]
Journal of Bacteriology, 1979 Methanogenic bacteria were found to form and oxidize methane at the same time. As compared to the quantity of methane formed, the amount of methane simultaneously oxidized varied between 0.3 and 0.001%, depending on the strain used. All the nine tested strains of methane producers (Methanobacterium ruminantium, Methanobacterium strain M.o.H., M ...

Chemotrophic Microbial Mats and Their Potential for Preservation in the Rock Record [PDF]
, 2009 Putative microbialites are commonly regarded to have formed in association with photosynthetic microorganisms, such as cyanobacteria. However, many modern microbial mat ecosystems are dominated by chemotrophic bacteria and archaea.

Removing Oxide Layers and Retaining Oxide‐Free Steel Surfaces by Polishing in Oxygen‐Free Atmosphere
Advanced Engineering Materials, EarlyView.In this study, the efficacy of wet mechanical polishing under an oxygen‐free atmosphere for deoxidation and the retention of an oxide‐free steel surface are elucidated using X‐ray photoelectron spectroscopy. The methodology proved successful; however, the results were highly dependent on the preparation of the solvents used to clean the samples after ...

Niche differentiation in nitrogen metabolism among methanotrophs within an operational taxonomic unit [PDF]
, 2014 Background: The currently accepted thesis on nitrogenous fertilizer additions on methane oxidation activity assumes niche partitioning among methanotrophic species, with activity responses to changes in nitrogen content being dependent on the in situ ...

Advanced Engineering Materials, EarlyView.Collagen hydrolysate is evaluated as a sustainable binder for MgO‐C refractories. Its thermally induced cross‐linking and gas release lead to expansion and cracking in large bricks, but tailored batches with lignin, recyclates, or fine graphite improve the gas release while thermal treatment and stability.
