Biocidic effect of nano metal fluorides against brown-rot fungi
2019 - IRG/WP 19-30732
Metal fluoride nanoparticles are promising because of their low water solubility, which reduces the need for fixatives required in widely used active ingredients in wood preservatives such as copper and boron. The effectiveness of nano metal fluorides was compared to sodium fluoride treated wood samples. Wood specimens treated with homo-dispersed sols of MgF2 and CaF2 were tested against brown-rot...

Use of resin obtained from Italian guayule crops for wood preservation purposes: some preliminary results
2019 - IRG/WP 19-30736
The potential of guayule (Partenium argentatum Gray) as a source of anti-termite, anti-fungal and insect repellent products to be used in wood preservation, has been largely explored in the past.
The fact that such products are obtained as byproducts in the process of natural rubber extraction from this plant, thus increasing the profit of the process, together with the ability of this crop to gr...

Exploring the use of X-ray micro CT as a tool for the monitoring of moisture production and mass loss during lab-based fungal degradation testing
2019 - IRG/WP 19-20654
Bio-based building materials, such as wood and wood-engineered products, are susceptible to degradation by decay fungi. In-depth knowledge on the intricate material-fungus relationship as well as performance data for many bio-based building materials are still lacking, and especially knowledge on how a material’s structure and moisture properties affect the degradation process is missing. Althou...

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...

Effect of nanoparticle impregnation on the biological durability of wood
2022 - IRG/WP 22-30772
This study evaluated the efficacy of five different nanoparticles (zinc-oxide, zinc-borate, silver, copper-oxide, copper-borate) applied with different concentrations against the brown rot Coniophora puteana and the white rot Coriolus versicolor. The generally effective nanoparticle treatments were the combinations containing borate in its chemical structure. However, only zinc-oxide and silver na...
