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...

Characterization of protein patterns from decayed wood of loblolly pine (Pinus taeda L.) by proteomic analysis
2008 - IRG/WP 08-10654
The primary biotic decomposers of wood belong to the basidiomycetes. The members of this group can attack and biodegrade both wood in the forest and in service. By the time wood decay is visible, there has already been a significant loss of strength. The identification of basidiomycetes and other organisms on wood only tell us what is present, not what is actively decaying the wood. When organisms...
