Comparative Evaluation of Additives in Softwood Fractionation: Impacts on Lignin Recovery and Pulp Quality. [PDF]
Chemical lignin stabilization during acid hydrotropic fractionation is shown to distinctly influence delignification, lignin quality, and pulp performance. Phenol enhances lignin removal, while thiol‐based modifier yields light‐colored lignin, high recovery, and strong pulp.

Fractionation of Wood Biomass With Thiolactic Acid and Choline Chloride-Based Solvent Into White Lignin for Sustainable Cooling Applications. [PDF]
A novel and highly efficient wood biomass fractionation method was developed to produce white lignin, exhibiting the brightest color reported to date. The process yielded white lignin with high yield, excellent visible light reflectance, and elevated infrared emissivity, highlighting its potential as an active material for passive radiative cooling ...

One-Step Extreme Delignification to Simultaneously Produce High-Purity Cellulose and Phenolated Lignin. [PDF]
An extreme delignification strategy using a formic acid–phenol–water system enables the simultaneous production of high‐brightness cellulose fibers and highly reactive phenolic lignin from various biomass sources, providing a sustainable pathway for high‐value utilization of lignocellulosic biomass.

Electrochemical Characteristics of Lignin in CTMP for Paper Battery Electrodes. [PDF]
Lignin naturally present in papers made of unbleached mechanical pulps is electrochemically active. Here, softwood chemi‐thermomechanical pulp (CTMP) is studied as an active cathode material for application in paper batteries. Proof‐of‐concept measurements are shown, and it is found that softwood CTMP fines exhibit competing oxidative electrochemical ...
