Canada-US Softwood Lumber Trade Revisited: Examining the Role of Substitution Bias in the Context of a Spatial Price Equilibrium Framework [PDF]

In the last two decades, softwood lumber trade between Canada and the United States has been characterized by numerous trade restrictions. Many studies have attempted to quantify the effects of such sanctions, and in doing so, softwood lumber was modeled

Upcycling Industrial Lignin Into Cationic Hydrogels With Potential for Sustainable Plant Protection

ChemSusChem, Volume 19, Issue 20, 28 October 2026.
Industrial lignin is upcycled into cationic lignin (CL) and embedded within chitosan–genipin (CH–GPN) hydrogels to form bioactive hydrogel networks with potential for antimicrobial plant protection. The CL‐embedded CH–GPN hydrogels retain porous, gel‐like properties and show enhanced in vitro inhibition of the plant pathogen Pseudomonas syringae.

Phosphorylation of Milkweed Fibers With a Phosphate Ester: Effect on Fiber Properties and Optimization of Reaction Conditions

Journal of Applied Polymer Science, Volume 143, Issue 40, October 20, 2026.
The phosphorylation of milkweed fibers using the phosphate ester/urea system was optimized. The impact of reaction temperature, duration, and phosphate ester ratio on the efficiency of phosphorylation was investigated using the design of experiments approach.

Material Characterization of Lignin‐Filled Polypropylene Composites

Journal of Applied Polymer Science, Volume 143, Issue 40, October 20, 2026.
Ground and spray‐dried lignin powders are compared as fillers for polypropylene composites. Differences in powder preparation methods are associated with differences in powder characteristics and composite behavior after melt compounding. Spray‐dried lignin produces smaller particles and fewer large agglomerates, while a 5 wt% lignin loading provides a
