The Preparatory (Anti)Bonding Character of Molecular Orbitals

Advanced Science, EarlyView.
Herein, a concept to qualitatively predict changes in bond dissociation energies upon reduction or oxidation of molecular compounds is introduced. Changing the population of so‐called preparatory molecular orbitals influences how molecular fragments are relaxing after bond cleavage, which is shown for isolated organometallic aluminum compounds as well ...

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.

De-oxygenation of CO2 by using Hydrogen, Carbon and Methane over Alumina-Supported Catalysts [PDF]

, 2012
The de-oxygenation of CO2 was explored by using hydrogen, methane, carbon etc., over alumina supported catalysts. The alumina-supported ruthenium, rhodium, platinum, molybdenum, vanadium and magnesium catalysts were first reduced in hydrogen atmosphere ...

Characteristics of rumen microbiota and Prevotella isolates found in high propionate and low methane-producing dairy cows

Frontiers in Microbiology
Ruminal methane production is the main sink for metabolic hydrogen generated during rumen fermentation, and is a major contributor to greenhouse gas (GHG) emission.

Methane Production by Microorganisms

Journal of the Fuel Society of Japan, 1980
Methane fermentation can be utilized as a fuel gas producing process from solar energy because plant-body can become the raw material f or methane fermentation. The bacteria which cause methane fermentation can be grouped into methanogenic bacteria which produce methane and non-methanogenic bacteria which produce substrates f or methanogenic bacteria ...

Chemoselective Metabolomics via a Modular Reactivity‐Encoding Platform

Advanced Science, EarlyView.
Conventional LC–MS underrepresents numerous metabolites due to heterogeneous ionization efficiencies and matrix interference. Here, we introduce a modular reactivity‐encoding platform (MREP) comprising four alkyne‐tagged probes that selectively derivatize key functional groups, followed by unified click‐chemistry capture to eliminate matrix components ...

Vertical distribution of methane oxidation and methanotrophic response to elevated methane concentrations in stratified waters of the Arctic fjord Storfjorden (Svalbard, Norway) [PDF]

, 2013
The bacterially mediated aerobic methane oxidation (MOx) is a key mechanism in controlling methane (CH₄) emissions from the world’s oceans to the atmosphere.

Ruminal Methane Production on Simple Phenolic Acids Addition in in Vitro Gas Production Method

Media Peternakan, 2009
Methane production from ruminants contributes to total global methane production, which is an important contributor to global warming. In this experiment, six sources of simple phenolic acids (benzoic, cinnamic, phenylacetic, caffeic, p-coumaric and ...

Establishment of pore volume compressibility model for rocks and analysis of its influencing factors

Duankuai youqitian
The pore volume compressibility (Cp) for rocks is a key parameter for evaluating the dynamic reserves of oil and gas reservoirs. However, the experimental measurement of this parameter is time-consuming, while the empirical formula method has limited ...
