Effects of preservative impregnations on wettability and surface free energy properties of Eucalyptus grandis wood
2023 - IRG/WP 23-40978
Wettability and surface free energy (SFE) are crucial parameters for evaluating the adhesion thermodynamics of solid surfaces. Hence, this study investigated the effects of copper azole (CA) and disodium octaborate tetrahydrate (DOT) preservative impregnations on Eucalyptus grandis wood wettability and SFE. Wettability was determined in terms of contact angles with polar (water) and non-polar (dii...

Evaluation of the water exclusion ability and inherent bioactivity of heartwood against decay in Japanese and European wood species via above-ground exposure and water absorption tests
2024 - IRG/WP 24-40998
The natural durability of wood has been thought to mainly depend on bioactive extractives and the water exclusion ability. To clarify the contribution of each factor to wood durability, above-ground exposure tests were conducted on Japanese and European wood species. A double-layer test was carried out using heartwood specimens of four wood species, i.e., Japanese cedar, Japanese cypress, Scots pi...

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...

Colorimetric performance of temperate wood species under tropical weathering
2025 - IRG/WP 25-41041
The appearance of wood, including its color and texture, is one of the most important features for its application as solid products, such as furniture, cladding, and terrace decking. Weathering can cause significant changes in the color of wooden products in outdoor applications, influencing their market acceptance and long-term performance. This study evaluated the colorimetric performance of fo...
