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 ...

Aromaticity is one of chemistry’s oldest concepts to describe the behavior of molecules. Chemists created it 150 years ago to help visualize and explain the bonding, structure, and reactivity of ...

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 ...

The novel compound is a new chapter in a story that began in 1825, when English scientist Michael Faraday first isolated benzene from gas lights. Benzene would later be identified as one of a class of ...

Aromatic medicinal plants derive their therapeutic value from complex mixtures of volatile compounds, yet the genetic logic that shapes these chemical profiles has long remained elusive.

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 ...

The flavor and fragrance company Symrise is working with the Belgian biotech firm ChemCom to identify aromatic compounds that block the receptors of unpleasant odors. The partners will use ChemCom’s ...

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 ...
