Methane is the most widespread volatile hydrocarbon and one of the most potent greenhouse gases. Marine sediments form the largest methane reservoir, from where large quantities of methane from gas-saturated sediments are released into the sea water

The determination of fatty acid composition using quantitative gas chromatographic (GC) analysis is a common method of characterizing fats and oils. A wide variety of derivatization methods have been developed to enable the GC analysis of non-volatil

Current approaches in diet-related bioarchaeological research focus on establishing major developments in ancient societies, whilst small-scale and high-resolution studies of social constituents of past food consumption have gained far less attention

Bromine formation in the mixture of solid NaBr and KNO3 was observed and the process was studied in different acidified organic solvent–water mixtures by monitoring the bromination of acetanilide and other compounds, containing activated aromatic s

Criteria that have been used to describe alkene strain can be divided into energetic and geometrical criteria. An overview of strain criteria from both groups is given, and altogether, 16 different criteria have been calculated with the DFT M062X/TZV

Steric strain, caused by forced deformation of double bond geometry, has significant impact on alkene reactivity, as was shown by a study of the gas-phase basicity of (E)-1-methyl-2-(1-methyl-2-adamantylidene)adamantane. The Gibbs free energy of the
