Elucidation of reactive sites of wood modified with acetic anhydride: Insights from density functional theory calculations
2020 - IRG/WP 20-40892
Density functional theory (DFT) was employed to investigate the interaction of cellulose and lignin with acetic anhydride for explaining the wood modification process. Atoms in molecules (AIM) and reduced density gradient (RDG) along with non-covalent interaction (NCI) plots were used to analyse the intermolecular bonding characteristics. Cellulose was modelled with a cellobiose unit (dimer of glu...

Mechanical and biological durability properties against soft-rot and subterranean termite in the field (grave-yard test) of beech wood impregnated with different derivatives of glycerol or polyglycerol and maleic anhydride followed by thermal modification in an opened or in a closed system
2021 - IRG/WP 21-40917
This paper presents mechanical and biological durability properties in soil beg test (soft-rot test) and field test (grave-yard test) against subterranean termite of the wood modified with an aqueous vinylic derivative of glycerol/polyglycerol or maleic anhydride cured in an opened or in a closed system. Wood modification was performed through impregnation of European beech (Fagus sylvatica) with ...

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...
