One was the formation of paraquinone chromophoric structures generated by oxidation of lignin, resulting in yellowing, another was the reduction of the paraquinone chromophoric structures to hydroquinones, leading to photo-bleaching, and indicated that photo-degradation of WPCs involved several factors including the wood flour content, coupling agents, manufacturing methods, and weathering conditions, and found that the lightness, total color change, as well as wood loss increased with exposure time [9].
In this project we not only plan to experimentally demonstrate the crucial role of the phonon-assisted dynamics in facilitating efficient energy transfer in chromophoric complexes and odour recognition, but also to develop a general theoretical framework to describe and understand the role coherent vibrations play in the dynamics of biomolecular systems, as well as to develop methods to identify the presence and properties of such vibrations.
