Published 2018 in ChemPlusChem: https://doi.org/10.1002/cplu.201800284FTIR spectroscopy and DFT were used to elucidate reaction energetics and spectral impacts of the cross-condensation reactions between lignin (a wood polymer) and poly(furfuryl alcohol). This has implications for "furfurylated" wood properties - an environmental benign wood protection method. Published 2017 in ChemistrySelect: https://doi.org/10.1002/slct.201702104A DFT benchmark study in relation to predicting vibrational properties, e.g. FTIR and Raman spectra, of the lignin polymer. A significant number of functionals and basis sets were tested.

Published 2003 in Biomacromolecules: 10.1021/bm025627j Optical spectroscopy is used to demonstrate charge transfer electronic states in lignin due to quinone−lignin interaction. This indicates that such states occur in all lignin-containing materials, and their possible role in lignin photochemistry, for example, photo-yellowing of paper, is suggested. Published 2003 in Chemistry of Materials. 10.1021/cm021162sThe oxidation of solid state lignin (in wood pulps) by laccase and other catalytic systems can be used to improve adhesion within wood pulp boards. EPR, UV-Vis and fluorescence spectroscopy show that general features of lignin oxidation, e.g. stable radicals, lead to improved adhesion. Published in 2002 in Progress in Biotechnology. https://doi.org/10.1016/S0921-0423(02)80015-6Spectroscopic methods are used to elucidate the impact of laccase catalyzed oxidation of solid state lignin. It is proposed that the oxidation is coupled with the transfer and stabilization of electronic hole states within the lignin.
