Wood Protection Using Nano Metal Oxides in Propylene Glycol
2022 - IRG/WP 22-30760
Metals and metal oxides are known to have properties that can protect wood from degradation. Nanoparticles, due to its unique physical and chemical properties can enhance the protection to a much greater extent. Major constraints in dealing with nanoparticle dispersion can only be resolved by identifying a proper dispersive medium. Studies were carried out by preparing nanodispersion of four metal...

Metabolite analysis of fungal COS degradation and phylogenetic investigation of COSase genes
2023 - IRG/WP 23-11018
Fungi are the major species causing microbial deterioration that reduces the commercial value of wood, such as wood decay and surface contamination, so it is important to accumulate knowledge on the physiology of fungi in order to develop countermeasures against these problems. Most physiological studies of fungi that have been reported have concerned the metabolism of carbohydrates as a source of...

Mini-stakes – an alternative test method for EN 252?
2023 - IRG/WP 23-20691
Market approval of wood treatment products requires knowledge and prove of long-term durability. Efficiency of wood treatment with a specific product is evaluated based on variety of tests, including penetration evaluation, leaching studies as well as decay tests. EN 252 standard test is a core method for wood durability evaluation in a ground contact, both for commercial product approval and scie...

UV protection and dimensional stability of lignin-based wood treatments
2023 - IRG/WP 23-40979
New developments in the field of wood modification aim to enhance the intrinsic properties of natural timber. The limitation of wood should be preferably achieved with biobased ingredients and efficient, eco-friendly treatments possessing low environmental impact. Consequently, new solutions assuring expected properties and functionality over elongated service life and reducing the risk of product...

Research on gaseous COS degradation by brown-rot fungus Gloeophyllum trabeum
2024 - IRG/WP 24-11033
Physiological studies of wood rotting fungi have mostly focused on the metabolism of carbon and nitrogen sources, which constitute the dominants components of wood. On the other hand, despite the physiological importance of trace elements such as sulfur, studies on their acquisition sources and metabolic pathways are limited. Until now, wood rotting fungi have been thought to utilize slight amount...
