Comprehensive Structural and Thermal Characterization of Selected Grass Lignins
… (H), guaiacyl (G), and sinapyl (S) moieties through ether and carbon-carbon linkages. Lignin is highly produced as waste and understanding structural characteristics of lignin will increase its utilization. Prairie cordgrass lignin (PCGL), switchgrass lignin (SGL), big bluestem …

The role of copper in aquatic photochemistry of dissolved organic matter
… and the photo-induced loss of electron-donating moieties of three selected DOM isolates (including both terrestrial and microbially derived DOM) under simulated sunlight irradiation. By using ultra-high resolution mass spectrometry, the results indicated that Cu selectively inhibited the …

Effects of plant flavonoids on the fate of polynuclear aromatic hydrocarbons in rhizosphere soil
… A biologically mediated covalent binding between phenolic moieties may be responsible for the enhanced bound residue formation. Relatively high percentage bound residues were found to be associated with higher clay, soil organic matter, and humus contents in soil. Increased bound residue formation …

Oxidation of Bisphenol A, Triclosan and 4-Nonylphenol by Fe-B* activated peroxide
… oxidation of each compound, producing phenolic radicals which then couple into dimeric products of each compound; increased FeIII-TAML concentration above 4 nM result in oligomers, forming dimer, trimer and tetramer (as detected by the LC-Tof-MS under negative ion mode). The 1H NMR …

Chemistry of hydroxycinnamate esters and their role as precursors to Dekkera produced off-flavour in wine.
… throughout the molecule. Those with deprotonated phenolic moieties possessed the most intramolecular electron movement, decreasing the HOMO-LUMO gap and promoting photoisomerisation. Smaller solvent and substrate effects were also noted, though the nature of the phenol and carboxyl clearly played …
