Limiting Polysaccharide Motion Protects Wood From Decay
2020 - IRG/WP 20-40890
It is well known that chemical modifications to improve decay resistance also reduce the equilibrium moisture content (EMC) of wood. The mechanism of this action, however, has been the subject of much debate. Several groups have suggested that decay resistance is a result of lower diffusion rates of fungal degradation agents through the wood cell wall. A recent paper explained the fundamental prin...

X-ray fluorescence microscopy of copper ion distribution in decay of copper-treated wood by Fibroporia radiculosa
2024 - IRG/WP 24-11047
Copper is an essential metal ion for eukaryotic life and must strictly be regulated as excess levels can cause oxidative damage, enzyme inhibition and denaturation, interruptions in nutrient transport and even cellular death. Copper-based wood treatments have efficacy against a wide range of biological organisms including decay fungi and are used in the majority of preservative formulations for ou...

Probing nanoscale protection mechanisms with x-rays and neutrons
2025 - IRG/WP 25-11083
While it is known that exposing wood to high levels of moisture, fire, or decay agents such as fungi can be detrimental for its performance, what is often missing in literature is a holistic understanding of how wood nanostructure changes due to these exposures. This is of particular interest since treatments that are meant to impart resistance can alter these length scales and/or modify their hyg...
