The potential of 2D NIR imaging for wood protection research
2015 - IRG/WP 15-20566
Investigating wood and wood-based materials using infrared spectroscopy has since long been explored. Recently, image-based systems have been developed that are used in food and pharmaceutical industries for rapid screening. Such hyperspectral cameras are able to collect spatial and spectral information simultaneously, resulting in a volume with a spectral profile for each pixel of the image. We p...

Evidence for a role for precipitated copper on the chemistry of micronized copper treatments
2016 - IRG/WP 16-30690
Micronized copper preservative treatments of softwoods, result in mobile copper being formed by reaction of the basic copper carbonate (BCC) with the carboxylic acid functional groups in hemicellulose and pectic substances present in wood. Typically, the amount of reacted copper formed is approximately 0.3% Cu m/m. In this paper, two examples are discussed where remaining unreacted basic copper ca...

Wood chemistry completes natural durability as criteria for shorting best provenances in the improvement of teakwood quality: case of five provenances from Ivorian Séguié’s trial
2018 - IRG/WP 18-10920
In order to determine the best provenance for continuing breeding program in Côte d’Ivoire, five provenances of teak planted in 1970 at Séguié’s trial (Agboville, in the south of Côte d’Ivoire), were compared. Fifteen trees (three trees per provenance) composed the sample. Decay resistance and the chemical content especially, non-structural carbohydrates, total phenolics and quinone comp...

Performance of bio-based building materials – durability and moisture dynamics
2020 - IRG/WP 20-20666
When exposed to conditions favourable for decay, bio-based building materials can be susceptible to degradation. Their ability to withstand deterioration over time (performance) depends on the intrinsic or enhanced durability of the material as well as its wetting and drying behaviour. The effect of fungicidal components in wood is known since long. Other material characteristics, such as the mate...

Decay capacity and degradation patterns of Xylaria hypoxylon on different wood species
2022 - IRG/WP 22-10985
A host of physical and environmental factors may influence fungal decay including the wood substrate, temperature, moisture, oxygen, light, pH, and nitrogen. Understanding the effects of these factors on fungal decay is important for the effective utilization of wood decay fungi in biotechnological processes and for understanding the role of these organisms in global carbon cycling. The ascomycete...
