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...

Optimising properties of citric acid-sorbitol bonded particleboards with added ammonium dihydrogen phosphate as fire retardant
2025 - IRG/WP 25-41033
Due to the adverse health effects of formaldehyde-based adhesives and their fossil origin, there is an ongoing search for appropriate bio-based adhesives for particleboards. Although there are some possible solutions, their use in construction is limited partly due to their low moisture resistance and flammability. The latter can be improved by adding various fire retardants. A particleboard with ...

Investigation of the Correlation between Blue-Light and Transparent Wood and Its Impact on Eye cells
2025 - IRG/WP 25-41042
The widespread use of LED blue light (400–480 nm) in modern life has raised concerns due to its potential risks to eye health, including retinal cell damage and vision degradation. Transparent wood, a renewable material with unique optical properties and environmental benefits, shows promising potential for blue light protection applications. This study investigates the modulation of lignin cont...

Preliminary assessment of imidazole as an adhesion system for particleboards
2025 - IRG/WP 25-41043
Particleboards with different combinations of adhesive mixtures containing imidazole, citric acid, and sorbitol were produced. Softwood sawdust from a Swedish sawmill was mixed with an aqueous solution of the chemicals and then dried to 0% moisture content prior to pressing. The boards were pressed to a target density of 700 kg m−3 at either 200 °C or 220 °C for 10 min. The hygroscopic and mec...

Physical and chemical characterization of post-consumer wood chips for recycling
2025 - IRG/WP 25-50414
Post-consumer wood (PCW) is a valuable resource that can partially substitute virgin wood in material applications. This communication paper presents key findings from a study that analysed PCW collected from three recycling facilities in southeastern Norway over eight months. A total of 20 mixed and 4 pre-sorted PCW samples were evaluated regarding their material composition, particle geometry, a...

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...
