Natural durability of four Tunisian Eucalyptus wood species and their respective compositions in extractives
2019 - IRG/WP 19-10942
In the 50’s, Tunisia government introduced more than 11 Eucalyptus wood species. Eucalyptus species were planted in Tunisia in different arboreta throughout the country for close observation and adaptation to climate and soil. These fast-growing wood species were mainly used as fire wood, for the production of mine wood and to fight against the erosion. These tree species were adapted themselve...

Time-of-Flight Secondary Ion Mass Spectrometry Analysis of Polyethylene Glycol Penetration into Wood Cell Walls
2006 - IRG/WP 06-20328
Penetration of high molecular weight polyethylene glycol (PEG) into wood cell walls was investigated in red pine. PEG of different molecular weights (1000, 8000 and 20000) was labelled by bromination and treated samples were analyzed on Time-of-Flight Secondary Ion Mass Spectrometry (TOF-SIMS) in dynamic mode. Both negative and positive spectra of the samples were collected in high spatial (bunche...
