Stabilized Cellulase in Chitosan–Polyvinyl Alcohol Biopolymer Beads for Sustainable Enzymatic Deinking of Recycled Paper

ChemistryOpen, EarlyView.
A stable and reusable biocatalyst, cellulase@Cs/PVA/Ga, is engineered by immobilizing cellulase onto glutaraldehyde‐activated chitosan (Cs) and coating it with polyvinyl alcohol. This composite system enhances enzymatic stability and efficiency for the sustainable deinking of recycled newspaper, offering a green alternative to harsh chemical treatments.

Enhancing the Functional Properties of Polylactic Acid by Incorporation of Esterified Lignin

Journal of Polymer Science, EarlyView.
Esterified lignin from agro‐industrial wastes enhances the hydrophobicity, UV‐shielding efficiency, and antioxidant capacity of polylactic acid composites. ABSTRACT Incorporating lignin as an additive is a promising strategy to overcome the limitations of PLA‐based composites.

Can Wapiti (Cervus elaphus) Browsing Stimulate the Chemical Defense of Taxus cuspidata—A Case of Northeast China Tiger and Leopard National Park

Integrative Zoology, EarlyView.
We study that browsing by wapiti reduces the growth of saplings, and it develop chemical defenses to prevent themselves browsed again. These results reduce our concern about wapiti browse T. cuspidate saplings, and provide basic data for the study of the interaction between them, and also provide theoretical basis for the population restoration and ...

From Hemp Bast to Lyocell Fiber: Sustainable Process Optimization for Lyocell‐Grade Dissolving Pulp

Journal of Applied Polymer Science, Volume 143, Issue 16, April 20, 2026.
This study presents a sustainable method to produce lyocell‐grade dissolving pulp from Canadian hemp bast fibers. A simplified alkali‐chelation‐bleaching process, free from sulfur and chlorine, yielded high α‐cellulose pulp with low lignin and hemicellulose content. The pulp was successfully spun into continuous hemp‐based lyocell fibers, demonstrating
