Beyond Brown: Lignin's Emerging Role in Structural Color

Advanced Optical Materials, EarlyView.
Lignin, long regarded as a brown industrial byproduct, is emerging as a sustainable platform for structural color. This Perspective highlights how lignin's refractive index, intrinsic absorption, and nanoscale assembly enable tunable photonic responses in colloidal and thin‐film architectures, and outlines design strategies to advance scalable, bio ...

Factors limiting o×ygen delignification of kraft pulp [PDF]

Canadian Journal of Chemistry, 2001
Softwood kraft pulp was subjected to a laboratory one- and three-stage oxygen delignification process. Pulp and liquor samples were collected at different stages of the process with particular attention being paid to the early and late stages. A novel residual lignin isolation method extracted about 65% of the oxidized residual lignins at a purity ...

Mechanistic Insights Into Cellulose Dissolution in Solvents for Advanced Industrial Applications: A Systematic and Bibliometric Review

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Cellulose dissolution is important for various industries, including textiles, bioplastics, foods and pharmaceuticals, yet achieving efficient dissolution remains challenging. Deep eutectic solvents (DES) have emerged as promising alternatives to traditional solvents due to their low toxicity, biodegradability and sustainability.

Development of a co‐culture of Ureibacillus thermosphaericus and Cupriavidus taiwanensis for inhibitors removal from hemicellulose prehydrolysate

Biotechnology Progress, EarlyView.
For biofuels production, hemicellulose pre‐hydrolysate is considered as an attractive feedstock rich in fermentable sugars. The pre‐hydrolysate derived from lignocellulosic biomass comprises, along with sugars, several inhibitors which can hamper its efficient conversion.

Valorization of Yacon (Smallanthus sonchifolius) peel for peroxidase production and its immobilization on alginate beads for 2,4‐dichlorophenol bioconversion

The Canadian Journal of Chemical Engineering, EarlyView.
Sodium alginate was modified with EDC/NHS for the immobilization of Yacon peel peroxidase, resulting in a novel biocatalyst for the oxidation of 2,4‐dichlorophenol. Abstract Yacon (Smallanthus sonchifolius) roots are emerging as an alternative source of peroxidase. This study aimed to extract, immobilize, and characterize the peroxidase from Yacon peel,
