OUT of the many methods suggested 1 for the quantitative determination of the total of aromatic constituents in mineral oils, none is suitable for giving information about the nature of these ...

The term aromaticity is a basic, long-standing concept in chemistry that is well established for ring-shaped carbon compounds. Aromatic rings consisting solely of metal atoms were, however, heretofore ...

NMR spectroscopy is a powerful technique that is ideally suited to the characterization and analysis of a diverse array of chemical compounds. Unlike many other analytical techniques, NMR spectroscopy ...

Researchers from The University of Osaka have developed a synthetic method that reliably and efficiently incorporates boron-rich carborane clusters into aromatic compounds as simple as "mixing and ...

A long-standing chemistry challenge has been solved with the synthesis of a five-atom silicon aromatic ring. The breakthrough validates decades of theory and points toward new industrially relevant ...

Aroma is an important sensory factor in the perception of food. But what exactly makes a food smell pungent, or savory, or foul? The chemistry of aroma, or smell, can be very complex. There are an ...

Scientists at the University of South Florida Health (USF Health) have discovered a new mechanism that helps neurons sense signals from the gut microbiome. The finding explains how fenchol—a natural ...
