Three‐Fourths of Carbon Emissions From 2023 Record‐Breaking Wildfires in Canada Traced to Soil and Peat Combustion

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract In 2023, wildfires burned vast areas in Canada, emitting large amounts of carbon (C). The area burned by the 2023 wildfires is the largest ever recorded in Canada, but the partitioning of C emissions between aboveground biomass and soil sources remains unknown.

One‐Pot Depolymerization, Demethylation, and Phenolation of Lignin for Bioactive Polyphenol Production

ChemSusChem, Volume 19, Issue 13, 14 July 2026.
Low‐cost lignin was upgraded in an acidic lithium bromide (LiBr) solution via integrated depolymerization, demethylation, and phenolation to yield bioactive polyphenols with enhanced phenolic hydroxyl content. The resulting polyphenols exhibited strong antioxidant and antibacterial activities, along with low cytotoxicity and promising in vivo ...

Effect of Relative Humidity Level on Bonding Properties of Black Spruce Glulam

BioResources
Glued-laminated timber (glulam) is a structural wood-based composite widely used in construction. One of the constraints to its production is the requirement that lamellae must have the same moisture content before bonding. This study analyzed the effect
