Non-stochiometric oxidation and ROS generation promoted by guaiacol lignin structures and lignocelluose surfaces may be a component of brown rot fungal degradation mechanisms
2019 - IRG/WP 19-10937
Model guaiacol compounds representing lignin monomers, as well as DHP-lignin and wood flour of controlled particle size were used to assess iron reduction at the pH of the natural wood cell wall. All compounds functioned as electron donors for ferric iron, with the lignin monomers demonstrating capacity for non-stochiometric reduction of iron with multiple moles of ferric ion reduced per mole of l...

Effect of pretreatment of wood surfaces with a copper monoethanolamine solution on the natural weathering performance of semitransparent stains
2019 - IRG/WP 19-40881
Semitransparent stains for wood products are favored for outdoor applications in Japan because these finishes do not hide the wood grain. However, the photoprotective effects of wood surfaces are low, therefor there is a need to improve the weathering performance. We examined the natural weathering performance of semitransparent stains on wood pretreated with a copper monoethanolamine solution (Cu...

Influence of weathering of wood surfaces before and after treatment with iron(II) sulphate
2023 - IRG/WP 23-30786
Outdoor wood is exposed to various factors that cause the wood to grey or age. The ageing processes can vary greatly depending on the exposure. Parts of the wood that are not exposed to external factors, e.g. under the eaves, are less exposed and the ageing process is therefore slower. This can be accelerated by solutions based on iron ions. In this way, the wood greys quickly and evenly. However,...
