Multifactorial analysis of the reasons behind wood natural durability
2025 - IRG/WP 25-11065
Physical, chemical and biological properties of several wood species were investigated in order to highlight the main factors involved in wood natural durability and wood characteristic using a principal component analysis. Interaction of wood with water were evaluated using contact angle measurements to determinate wood wettability by water and wood impregnability tests with water allowing to cal...

From Wet to Preserved: Collecting Data of Waterlogged Wood Treated with PEG in Lanyan Museum and Study the Effect of Molecular Weight on Dimensional Stability
2025 - IRG/WP 25-11080
Waterlogged archaeological wood are most commonly unearthed in Yilan County, with over one-third originating from the Yilan Agricultural School site. This study aims to analyse the current state of conservation of waterlogged archaeological wood in Yilan County and hopes to properly alleviate the irreversible damage caused to the waterlogged archaeological wood after they leave the water layer. Ho...

Evaluation of 'Deep Penetration Treatment' for wood preservation
2025 - IRG/WP 25-20746
‘Deep Penetration Treatment’ (DPT) is a recently developed wood preservation technique in Japan designed to meet the preservation standards required for residential foundations. This method involves spraying a specially formulated solvent-borne wood preservative onto properly incised dried lumber. Despite being a non-pressure treatment, DPT achieves penetration levels comparable to conventiona...

The impact of common fire retardancy salts and minerals on further properties of wood
2025 - IRG/WP 25-30821
Wood has become an increasingly important construction material. To ensure fire safety, fire retardants are widely applied. Recent research focuses on environmentally friendly fire retardants with strong fixation. Phosphate-based salts like diammonium hydrogen phosphate show high fire protection potential but are highly leachable due to their good water solubility. As a newer trend mineralisation ...

Unlocking the Potential of Dairy Coproducts in Wood Modification
2025 - IRG/WP 25-30822
The production of dairy coproducts, such as whey (sweet or acid) and whey ultrafiltration permeate, has significantly increased in response to the rising global cheese consumption. Proteins found in by-products are purified for human nutrition. However, upcycling lactose, which is the major compound of cheese by-products, is more challenging due to the high cost of upcycling processes. Furthermore...

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...
