Application of nano metal fluorides against termites
2019 - IRG/WP 19-30733
Recent research has shown that fluorides such as NaF have potential as a wood preservative against termite attack (Pan and Wang, 2015). However, NaF has high leaching susceptibility because of its solubility (40 g/l ) which can reduce its efficacy over long term. Metal fluoride nanoparticles such as MgF2 and CaF2 present a viable alternative to water soluble fluoride-based wood preservatives as th...

Effect ofNano-Copper Oxide on Decay Resistance of Pistachio Twig-Plastic Composite
2019 - IRG/WP 19-30750
The goal of our study was to investigate the decay resistance of pistachio twig-plastic composite treated with nano-copper oxide against the white rot fungus Trametes versicoloer and the brown rot fungus Coniophora puteana. For this purpose, wood–polypropylene composites (WPCs) containing different loadings of nano-copper oxide, namely 0, 1, 2 and 3 percent (W/W), were made from pistachio (Pista...

Wood Protection Using Nano Metal Oxides in Propylene Glycol
2022 - IRG/WP 22-30760
Metals and metal oxides are known to have properties that can protect wood from degradation. Nanoparticles, due to its unique physical and chemical properties can enhance the protection to a much greater extent. Major constraints in dealing with nanoparticle dispersion can only be resolved by identifying a proper dispersive medium. Studies were carried out by preparing nanodispersion of four metal...

Effect of nano-particle characteristics and concentration on UV protection of timber: A field exposure test
2022 - IRG/WP 22-40941
Wood has a well-known susceptibility to ultra-violet light degradation, leading to premature replacement. A variety of products have been developed to protect against this damage, but most provide less than 12 months of protection and must be regularly reapplied. Developing improved coatings would help reduce wood losses and reduce maintenance costs. Nano-particles have a variety of attractive pro...

Assessing changes in hardness of furfurylated wood on a nano-scale to mimic levels experienced by the marine wood-boring crustacean, Limnoria
2023 - IRG/WP 23-11016
Wood-boring crustaceans and bivalves can cause severe damage to wooden structures in the marine environment, warranting the need for novel protection systems, such as chemical modifications. Furfurylation increases mechanical properties and resistance of timber species that would usually be susceptible to biodegradation by these borers, such as pine. In rapid laboratory and field testing, furfuryl...

Evaluation of the efficacy of silver nanoparticles and chitosan oligomer composites as poplar wood protective treatments against termites
2023 - IRG/WP 23-40963
Populus × euramericana ‘I-214’ (poplar) is a fast-growing species widely distributed throughout the world, and in the Castile-Leon region of Spain it accounts for more than 50% of all plantations. Its wood is becoming increasingly appreciated, yet its low durability against xylophagous agents —termites being one of the most aggressive and destructive in warm climates— continues to be a li...
