Predicting weather resistance of Recoated Outdoor Wood by Near Infrared Diffuse Reflectance Spectroscopy
2025 - IRG/WP 25-20757
Wood exposed to the outdoors causes slow degradation. One wood treatment to retain this degradation is paints and stains, and recoating is essential process for these coated wood products to achieve a long service life. We investigated that possibility of using near infrared spectroscopy to estimate repair condition and weather resistance of recoated outdoor wood. The specimens used for recoating ...

Decay resistance of thermally modified Eucalyptus grandis in closed and open systems
2025 - IRG/WP 25-30815
Thermal modification has been successfully used to improve the durability of Eucalyptus wood from fast-growing forests. Although it is the most common type of modification process, there are some fields for studies on thermally modified wood, particularly about the comparison between processes in closed and open systems. This work aimed to analyse the effect of thermal modification in closed and o...

Novel treatments of solid wood - studies into the use of imidazole and succinimide
2025 - IRG/WP 25-30817
Recent activities have focussed on the use of ionic liquids (ILs) in wood treatments and bioprocessing. Most ILs are based on imidazolium systems, so it was decided to investigate the potential of imidazole as a treatment, along with another heterocyclic compound, namely succinimide. Thus, modification of Scots pine sapwood (Pinus sylvestris L.) with heterocyclic compounds, imidazole and succinimi...

Enhanced Termite Resistance of Low Durability Fast Growing Teak Wood by Non-Biocide Treatments Based on Chemical and Thermal Modification
2025 - IRG/WP 25-30818
Short rotation teak as a fast-growing tree can be considered as a renewable material resource for the future green economy. However, short rotation teak wood is susceptible to biodeterioration, particularly to termite attack. The objective of this work was to investigate the effect of chemical and thermal treatment on resistance of sapwood, transition wood, and heartwood of short rotation teak aga...

Mineral-wood composites with improved fire properties and durability prepared through MgCO3-based mineralization
2025 - IRG/WP 25-30823
New mineral-wood composites that demonstrate improved fire properties and higher resistance to selected fungi have been prepared using an environmentally-friendly mineralisation process involving impregnation with an aqueous magnesium acetoacetate solution. MgCO3-based compounds are formed in situ, deep within the wood’s structure. We show that the new mineralisation method overcomes wood’s lo...

Enhancing strength, fire and biological resistance of wood through structural and chemical modification
2025 - IRG/WP 25-30831
Wood, a renewable and versatile biopolymer, has been a fundamental material to construct traditional and advanced composites for building construction, furniture, transparent composites, and various other applications. Despite its many advantages, including its aesthetic appeal, workability, and relatively low cost, wood possesses inherent limitations such as susceptibility to biological, flame an...

Performance Verification of Water-Based Outdoor Wood Protection Coatings Based on Weather Resistance Evaluation
2025 - IRG/WP 25-41015
Recent trends in wood protective coatings: Concerns over volatile organic compound (VOC) emissions and the need to reduce maintenance costs have increased demand for environmentally friendly and highly durable coatings. While conventional solvent-based paints are superior in durability, they have been associated with problems such as environmental impact and odour during application. As an alterna...

Effect of photodegradation on fungal colonization on wood during initial stage of brown-rot decay
2025 - IRG/WP 25-41024
Photodegradation and decay may happen simultaneously on wood under many exposure conditions. The aim of this study was to explore the effect of photodegradation on fungal colonization during initial stage of brown-rot decay of wood. For this purpose, southern pine (Pinus spp.) wood was exposed to accelerated UV weathering for different durations, and then decayed by a brown rot fungus (Gloeophyllu...

Fungal decay in cable car pylons in Svalbard - overview of results
2025 - IRG/WP 25-41026
A total of 212 iconic wooden cable car pylons were constructed for mining operations in Svalbard, significantly contributing to Longyearbyen's historical identity as a mining town. Fieldwork in Svalbard involved collecting wood samples from 22 of these pylons, targeting wood exposed both aboveground and ground proximity. Whilst the timber used in the constructions was assumed to be untreated Norwa...

Biocomposites based on fungal mycelium and beech particles impregnated with BPCM (bio-phase change material) for thermal energy storage
2025 - IRG/WP 25-41034
The building sector is a major contributor to Europe's carbon emissions, and transition to a bio-based economy is essential for achieving long-term sustainability goals. The European Union has set ambitious targets for climate-neutral heating and cooling by 2050, which requires the widespread adoption of energy-efficient and environmentally friendly technologies. A key element in this transition i...

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...
