Structural characterization of Argania spinosa Moroccan wooden artifacts during natural degradation progress using infrared spectroscopy (ATR-FTIR) and X-Ray diffraction (XRD).
TL;DR: Spectroscopic study of four samples of Argan wooden artifact pertaining to the 17th, 18th, 20th and 21st centuries to characterize their unknown structures by the study of their non degraded parts and to investigate changes occurred in their degraded parts due to the natural degradation process.

Effects of UV weathering on surface properties of polypropylene composites reinforced with wood flour, lignin, and cellulose
TL;DR: In this article, the influence of accelerated weathering on polypropylene composites reinforced with wood flour (WF), lignin, and cellulose at different loading levels were evaluated, and the results revealed that the discoloration of composites was accelerated by the presence of Lignin especially at high content.

Yellowing and IR-changes of spruce wood as result of UV-irradiation
TL;DR: The results show that the photoyellowing (UV-Vis detection) correlates very well with lignin degradation (IR detection), in agreement with the quinone formation as the chromophoric reaction product of lign in decay.

Studies of the degradation and protection of wood surfaces.
TL;DR: In this paper, the FTIR internal reflectance spectroscopy was used to study chemical changes taking place at the wood surface upon treatment and during weathering, and the spectra obtained provide direct evidence for the modification and stabilization of the lignin aromatic system with aqueous chromium trioxide and to a lesser extent with ferric salts.

Surface degradation of wood by ultraviolet light
David N.-S. Hon,Shang-Tzen Chang +1 more
TL;DR: In this paper, surface characteristics of ultraviolettreated wood were analyzed by infrared and ultraviolet spectroscopy, and it was shown that ultraviolet-treated wood is rich in carboxylic and carbonyl chromophoric groups and poor in aromatic functional groups.
