In this study, pulped cellulose fibres were pre-treated with aqueous morpholine prior to mechanical disruption in the production of cellulose nanofibrils (CNF). The properties of the morpholine pre-treated CNF (MCNF) were closely compared with CNF ob...

Onyianta, A. J., & Williams, R. (2017, June). The Use of Sedimentation for the Estimation of Aspect Ratios of Charged Cellulose Nanofibrils. Presented at 3rd International Conference on Natural Fibers ICNF 2017, Braga, Portugal

In this study, the aspect ratios of carboxymethylated and TEMPO-oxidised cellulose nanofibrils (CNF) were estimated by gel point analysis using a sedimentation approach. The flocculation and subsequent sedimentation of the CNF aqueous suspensions, wh... Read More about The Use of Sedimentation for the Estimation of Aspect Ratios of Charged Cellulose Nanofibrils.

β-1-4-Galactan has been detected in Sitka spruce [Picea sitchensis (Bong.) Carrière] by an immunofluorescence procedure. The anti-β-1-4-galactan monoclonal antibody LM5 was found to bind to compression wood (CW) tissue as identified by cell morpholog...

Relationships between mechanical properties, weight loss and chemical composition of wood during incipient brown rot decay. (2002)
Journal Article
Curling, S., Clausen, C. A., & Winandy, J. E. (2002). Relationships between mechanical properties, weight loss and chemical composition of wood during incipient brown rot decay. Forest Products Journal, 52, 34-39

Incipient decay of wood by brown-rot fungi causes measurable strength losses in wood before measurable weight loss occurs. Previous studies have shown that the high levels of strength loss that occur during incipient brown-rot decay may be related to...

A biological exposure method was developed that allows wood samples to be progressively removed for monitoring colonization and decay by basidiomycete fungi. Monitoring involves strength tests, determination of weight loss, and chemical analysis. To...
