A review on prediction methods of wood natural durability
2017 - IRG/WP 17-10892
Natural durability of timber may be defined as “inherent ability of timber to attack by wood destroying organisms (bacteria, fungi, insects, marine borers) without preservative treatment. On the base of biological tests, EN-350-2 standard (Afnor, 1994), describe the classification of wood species according to their natural durability. But these specifications are not adapted in the case of wood ...

Comparison of 1H qNMR and NIR spectroscopic methods to predict heartwood decay resistance in Dicorynia guianensis Amsh
2017 - IRG/WP 17-20601
Dicorynia guianensis is by far the most exploited wood in French Guiana, as it is an abundant tree species associated with good technological properties. However, the decay resistance of D. guianensis wood against lignivorous fungi pathogens is sometimes variable. Therefore, the development of tools to predict the decay resistance of D. guianensis heartwood is relevant in wood science and agrofore...

Profiling fungal degradation of Scots pine sapwood by short wave infrared hyperspectral image analysis
2020 - IRG/WP 20-20667
Hyperspectral image analysis of Scots pine sapwood wood affected by decay fungi has been carried out as part of a Ph.D. thesis within the project Remote Inspection of Wooden Utility Poles (RIWUP).
In a lab experiment, Petri-dishes with Scots pine sapwood samples on malt agar medium were infected with two types of decay fungi, a brown rot and a white rot. The wood samples were scanned with a HySpe...

Discrimination of five commercial wood preservatives by handheld near-infrared spectrometers and Multivariate Data Analysis
2022 - IRG/WP 22-20686
Nowadays, the recycling potential of wood waste is still limited, because of a lack of reliable lack of a reliable and fast device allowing the discrimination of preservative-treated wood that contains organic or/and inorganic contaminants. The purpose of this study was to set up a methodology, based on a SCiO low-cost handheld NIR spectrometer, and multivariate data analysis (MDA). Spectra was ob...
