Synergy discovered between enzymatic decomposition and mechanical stress in reducing the mechanical properties of solid wood

Both biotic and abiotic factors contribute to wood degradation. The biotic factors cover microbial activity which by a variety of enzyme systems is capable of deconstructing wood cell walls, whereas …

Moisture in wood near or at saturation. Part 1: how much water can solid cell walls accommodate?

Wood is a hygroscopic material that absorbs and exchanges water molecules with the surrounding environment if it is exposed to water vapour or liquid water. Water molecules within the wood …

Moisture in wood near or at saturation. Part 2: how much, where is it, and what state is it in?

In wood, water is taken up both in cell walls and as capillary water in macro voids such as cell lumina and pit chambers. Because of the relatively large dimensions …

Effects of acetylation on moisture in wood

Wood is a naturally hygroscopic material, and the atmospheric water molecules interact with sorption sites in the cell wall, causing changing moisture contents depending on the relative humidity of the …

Targeted acetylation of Norway spruce tissue and its effect on moisture states in wood

Due to the inherent biological nature, wood is susceptible to microbial degradation. Traditionally, broad toxicity biocides have been used to protect wood against decay, but these are gradually being phased …

Natural durability of wood exposed above ground

To find the most suitable wood species for different outdoor applications, different wood species should be compared on the same basis. This means, among other things, the same dimensions and …

Controlling amount and location of water at high well-defined moisture states by targeted wood modification

Water is an essential requirement for fungal degradation, but the exact role of water is not fully understood (Brischke & Alfredsen 2020). Fungal hyphae need capillary water (Rayner & Boddy …

Emil Engelund Thybring / Lisbeth Garbrecht Thygesen / Maria Fredriksson / Ramunas Digaitis

Targeted Acetylation of Wood: a Tool for Tuning Wood-water Interactions

Wood susceptibility to fungal degradation may be reduced by a range of non-toxic wood modification methods. Some modification methods alter wood-water interactions, which could be the reason for its improved …

Raman Microspectroscopy of Native and Acetylated Wood at Different Relative Humidities Using a Tailored Moisture Chamber

Understanding wood-water interaction is crucial to predict and possibly manipulate dimensional changes and degradation of structural wood (Sandberg 2017; Thybring 2021; Thybring 2018). Raman Spectroscopy (RS) has been used with …
