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 ...

Ozonólise das ligninas organossolve e kraft eucalipto. Parte II: cinética nos meios ácido e básico Ozonolysis of organosolv and kraft eucalyptus lignins. Parte II: kinetic in basic and acid media

Química Nova, 1998
Organosolv and kraft lignins were treated with ozone both in basic and acid media and the reaction was studied kinetically. In contrast to reported studies, ozone was more efective in basic medium.

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.

Kraft lignin reaction with paraformaldehyde

Holzforschung, 2019
AbstractLignin is the second most abundant biopolymer and will be an important source for carbon-containing compounds in the future. Based on their similar phenolic structures, lignin has great potential to become a valuable substitute for phenol in phenol-formaldehyde resin adhesives. To meet this aim, the sodium hydroxide (NaOH)-catalyzed reaction of

Elucidating the Interplay Between Structure and Electrochemical Behavior in Lignin‐Based Polymer Electrolytes for Potassium Batteries

Battery Energy, Volume 4, Issue 2, March 2025.
Three biobased membranes are synthesized by crosslinking oxidized Kraft lignin with poly(ethylene glycol) diglycidyl ether of increasing molecular weights. After incorporation of solvated potassium salts, potassium batteries including these biobased gel polymer electrolytes are able to deliver a maximum specific capacity at 0.05 A g−1 as high as 130 ...

Exploration of the Linkages between Lignin and Carbohydrates in Kraft Pulp from Wheat Straw Using a ¹³C/²H Isotopic Tracer

Molecules, 2023
To further our understanding of the change in association between lignin and carbohydrates after kraft pulping, isotope-labeled kraft pulp (KP) was prepared using 13C and D double-isotope-labeled wheat straw, and it was subjected to enzymatic hydrolysis ...

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.
