Leaching and chemical redistribution of CCA components in refractory heartwood of E. nitens
2024 - IRG/WP 24-41011
Chromated Copper Arsenate (CCA) is a wood preservative widely used to protect against fungal and insect attack. The fixation mechanism of CCA involves complex chemical reactions, including the reduction of chromium (VI) to chromium (III) and the formation of insoluble complexes. Despite fixation efforts, a portion of CCA components tends to leach from treated wood, influenced by factors like wood ...

Effect of Deep Eutectic Solvent Pretreatment on Properties of Densified Wood
2025 - IRG/WP 25-30824
Densified wood is preferable for structural applications because of its excellent mechanical properties and sustainability, but the fixation of its compression deformation and the prevention of water-induced mechanical deterioration remain challenging. Herein, an eco-friendly and highly efficient method was designed for producing dimensionally-stable densified wood, including deep eutectic solvent...
