Wood protection techniques and natural weathering: their effect on aesthetics and preference of people
2019 - IRG/WP 19-50351
Current research successfully contributes to improving wood protection techniques. However, the vast majority of research on preventing degradation of wood ignores a critical aspect of making successful products and processes – user selection of materials, which may largely depend on the aesthetical qualities. Wood treatments change the tactile and visual properties of wood substantially and the...

The influence of chemical compounds on wood cell wall to surface cracks
2020 - IRG/WP 20-40908
Degradation due to cracking and dimensional changes caused by drying, have a significantly negative impact on the preservation and durability of wood. Therefore, the prevention of surface cracking, which tends to occur during the drying process, is vital. High temperature set drying is one of the most effective methods for preventing wood surface cracking. It begins with softening the wood at a hi...

DuraSoft Project: a multidisciplinary approach for softwood protection
2021 - IRG/WP 21-50367
Over the course of millennia, fishing and agro-pastoral activities have produced unique housing types in the Italian lagoons and in the Slovenian highlands where the use of wood is predominant. They are associated with wooden service infrastructures such as piers, moorings, piling and fences. However, the existence of these structures and the associated cultural heritage are subject to constant ...

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...

Morphological observation of wood at the early stages of decay in brown rot and white rot
2023 - IRG/WP 23-11020
Wood rotting fungi, the fungal species causing biodeterioration for wood building, are generally classified into white-rot, brown-rot and soft-rot fungi based on their decay modes. Since white-rot and brown-rot fungi are known to reduce wood strength significantly, it is important to clarify the mechanisms of their wood degradation. White-rot fungi reduce wood strength as the decay progress and de...

Characterization of cell wall morphology and water-soluble extractives in Japanese larch decayed by white-pocket-rot fungi
2024 - IRG/WP 24-11034
Porodaedalea chrysoloma (Fr.) Fiasson & Niemelä is a basidiomycete that can cause white-rot decay in Japanese larch (Larix kaempferi) heartwood. P. chrysoloma is a white-rot fungus with a unique pattern that causes white-pocket-rot in the xylem of Japanese larch. However, the mechanism by which P. chrysoloma yields the pattern of white-pocket-rot in Japanese larch heartwood remains unclear. Thus,...

Investigating moisture dynamics and fungal decay risk: integrating X-ray CT visualization and simulation benchmarks through a Fungal Control Unit
2024 - IRG/WP 24-11045
Wood is susceptible to fungal attack and over time the structural integrity can be compromised. This risk is of course strongly related to moisture dynamics, as moisture is needed for fungal growth. While existing methodologies, such as lab and field tests, provide valuable insights into wood decay, they often fall short in replicating real-life conditions, particularly within the intricacies of t...

Interaction of cellulolytic enzymes with fungal cell wall polysaccharides
2025 - IRG/WP 25-11071
Wood rotting fungi are the primary agents responsible for the decomposition of wood in natural environments. These fungi secrete a variety of enzymes to degrade the chemically and structurally resistant components of the wood cell wall. Some of these enzymes possess a carbohydrate-binding module (CBM), which enhances enzymatic efficiency by increasing their affinity to the substrate. Previously, w...

Exploration of flavoenzymes from the wood rotting basidiomycete Armillaria cepistipes using protein structure prediction
2025 - IRG/WP 25-11077
Wood rotting basidiomycete is one of the major organisms that cause wood deterioration. Oxidoreductases secreted by those fungi are known to play key roles in the mechanism of wood cell wall degradation. As certain extracellular oxidoreductases including lignolytic peroxidases and lytic-polysaccharide monooxygenases from wood rotting fungi utilise hydrogen peroxide as a substrate in their catalyti...

Enhanced Flame Retardancy in Wood via In Situ Polymerization of Phosphorus-Containing Ionic Liquids
2025 - IRG/WP 25-20736
Wood, a ubiquitous material in furniture and construction, is limited by its natural flammability. Existing wood flame retardant technologies are often ineffective and lack environmental sustainability. Ionic liquids (ILs), known for their non-flammability and non-volatility, offer a green solvent solution to these challenges. In this study, we synthesized a novel phosphorus-containing, polymerisa...

Functionalization of wood with nano-sized titanium dioxide – Efficacy against mould growth and effect on cell wall integrity
2025 - IRG/WP 25-20740
Nano-sized titanium dioxide (nano TiO2) is a photocatalytic compound that generates reactive radicals under UV radiation, which can inhibit microbial growth and impart self-cleaning properties. This effect has been widely utilised on materials such as glass or tiles. This study investigates the potential of nano TiO2 treatments to prevent mould growth on wood and their impact on cell wall integrit...

The Impact of Drying Techniques on the Quality of Thermally Modified Wood
2025 - IRG/WP 25-30813
The wood drying technique applied before loading the dry wood into the ThermoWood® kiln may affect its properties. For this purpose, Scots pine (Pinus sylvestris) boards were first dried through three drying methods, including radio-frequency/vacuum (RF/V), mild, and moderate conventional drying, and then loaded into a ThermoWood® kiln for thermal modification at 212 °C for 3 hours according to...
