Evaluation of decay and energy properties from thermally modified biomasses during fungal deterioration by NIR-spectrometry
2021 - IRG/WP 21-40922
This study is focused on the prediction of fungal weight loss (WL) and high heating value (HHV) from raw and torrefied waste lignocellulosic feedstocks, according to their exposure duration to wood-destroying fungi, using near infrared spectroscopy (NIR) and chemometrics models.
Sugarcane bagasse, coffee husk, eucalyptus and pine shavings were torrefied at 290 °C in a screw reactor, during 5, 7...

Wood boring species present in the Tagus Estuary and the severity of their attack on wooden piles exposed in the area: a case study
2008 - IRG/WP 08-10664
Wood exposed in the marine environment is subject to degradation by wood boring organisms. This is probably one of the reasons why wood has been substituted by concrete and steel in maritime structures in many European coastal areas. Wooden piles obtained from a wharf exposed in the Tagus Estuary, Porto Brandão (Almada, Portugal) provided an opportunity to understand the main

Application of nanoparticles of silver and nanoparticles of titanium dioxide in reinforcement of wood and coating for wood in Costa Rica
2015 - IRG/WP 15-40698
Wood is one of the most widely used materials in last 20 years by society in many applications, with a considerable proportion of this material coming from forest plantations. Plantations usually produce timber with reduced strength properties and low natural durability. On the other hand, nanotechnology applications have the potential to increase wood properties. Likewise, nanotechnology cannot o...
