End Coating Masson Pine Grown in South China to Prevent the Development of Blue Stain
2007 - IRG/WP 07-30428
One end (randomly selected) of logs of mason pine (Pinus massoniana) were coated with a wax-type end coating called ANCHORSEAL® immediately after tree cutting. The logs were then stored in summer weather in Guangxi, China. During the storage, at week 1, 2, 3, 4, 6, 8 and 12, five logs of mason pine were sawn into lumber or veneer for the visual observation and measurement of blue stain at the coa...

Preparation and characterization of activated carbon fibers prepared from liquefied wood
2013 - IRG/WP 13-40636
Activated carbon fibers were prepared from liquefied wood through stream activation. The effects of activation temperature and time on the microstructure and surface functional groups of the liquefied wood activated carbon fibers (LWACFs) were studied using analysis of burning behavior, X-ray diffraction, nitrogen adsorption-desorption isotherms, X-ray photoelectron spectroscopy, and SEM. The resu...

A novel anti-fungal wood crack repairing agent based on CQDs/PVA
2025 - IRG/WP 25-20744
Wood is a sustainable material, but its tendency to crack and decay poses a challenge for its applications. In this study, we developed a combination system of nitrogen-doping carbon quantum dots (N-CQDs) and polyvinyl alcohol (PVA) to repair wood cracks. Rather than employing the conventional repairing methods such as filling cracks with sawdust and petroleum based-adhesives, this technique can m...

Carbon quantum dots as a fungicide and its applications in wood
2025 - IRG/WP 25-20754
In this work, we synthesised nitrogen-doped carbon quantum dots (CQDs) via a microwave assisted method. CQDs with proper structure showed excellent anti-fungal effects against both brown (Postia placenta, Pp) and white rot decay fungi (Trametes versicolor, Tv) on wood. The underlying anti-fungal mechanisms of CQDs on wood were further elucidated. We found that positively charged nano-sized CQDs pr...
