Journal ArticleDOI

Understanding decay resistance, dimensional stability and strength changes in heat-treated and acetylated wood

TL;DR: The cell-wall moisture content is too low in acetylated wood to support fungal attack so the initial enzymic attack starting the colonization does not take place as discussed by the authors.
Journal ArticleDOI

Rapid analysis of the chemical composition of agricultural fibers using near infrared spectroscopy and pyrolysis molecular beam mass spectrometry

TL;DR: In this paper, the chemical composition of a variety of agricultural biomass samples was analyzed with near infrared spectroscopy and pyrolysis molecular beam mass spectrographs, and the analysis showed that both spectroscopic tools, coupled with multivariate analytical techniques, could be used to differentiate the samples and accurately predict the chemical compositions of this disparate set of agricultural residue samples.
Journal ArticleDOI

Characteristics of cotton cellulose depolymerized by a brown-rot fungus, by acid, or by chemical oxidants

TL;DR: In this article, the authors compared four types of depolymerized cellulose with those of cellulosedepolymerizcd by acid (A), Fenton's reagent (Fe 2+ + H 2 O 2 ) (F), or periodic acid/bromine/water (P), and showed that brown-rot cellulose resembles sample F more than sample A or P.
Journal Article

Effects of processing method and moisture history on laboratory fungal resistance of wood-HDPE composites.

TL;DR: In this article, the effects of composite processing and moisture sorption on laboratory fungal resistance of wood-plastic composites were investigated using a 12-week exposure to the brown-rot fungus Gloeophyllum trabeum.
Journal ArticleDOI

Characterization of palo podrido, a natural process of delignification in wood.

TL;DR: The structural changes in lignin during the white rot degradation were examined by thioacidolysis, which revealed that the beta-aryl ether-linked syringyl units were more specifically degraded than the guaiacyl ones, particularly in the case of selective delignification.
