Effect of delignification on thermal degradation reactivities of hemicellulose and cellulose in wood cell walls

open access: yesJournal of Wood Science, 2021
The thermal degradation reactivities of cellulose and hemicellulose are substantially different in Japanese cedar (Cryptomeria japonica, a softwood) and Japanese beech (Fagus crenata, a hardwood). Uronic acid and its salts act as acid and base catalysts,

Species‐Specific Adaptability in Seasonal Resource Use by Non‐Breeding Crows: Contrasting Responses to Natural and Anthropogenic Environments

open access: yesEcological Research, Volume 41, Issue 4, July 2026.
Two sympatric crow species showed distinct resource use during the snow‐free season, exploiting different environments and anthropogenic resources. In contrast, during winter, both species converged on similar habitats and food resources under snow cover. These results highlight flexible, season‐dependent resource use in non‐breeding crows.

Effect of grooving pretreatment on flame retardant vacuum-pressure impregnation performance of full-size timbers

open access: yesJournal of Wood Science
We reported in a previous study that wood fiber orthogonal grooving improves flame retardant vacuum-pressure impregnation performance. However, it was limited to small sample sizes.

Engineered Microbial Production of 2-Pyrone-4,6-Dicarboxylic Acid from Lignin Residues for Use as an Industrial Platform Chemical

open access: yesBioResources, 2016
As one of the most abundant materials in nature, lignin has been used widely in co-generation operations and for fine chemicals and bio-fuels production. These uses, although important, are of relatively low value. Lignin contains many aromatic compounds

Thermal reactivity of hemicellulose and cellulose in cedar and beech wood cell walls

open access: yesJournal of Wood Science, 2020
Wood cell walls have complex ultra-structures, in which cellulose microfibrils are surrounded by a hemicellulose–lignin matrix. This is the first paper to discuss the effect of cell wall on the pyrolytic reactivity of hemicellulose and cellulose in wood ...
