Summary: New sustainable composites were obtained using epoxidized linseed oil (ELO) and kraft lignin (LnK) through a double-curing procedure involving UV radiation and thermal curing. The study confirmed crosslinked structures using FTIR and investigated thermal degradation behavior, dynamic-mechanic behavior, and water affinity. Results showed that increased LnK content led to better thermal stability and increased Tg values, with excellent corrosion protection efficiency in carbon steel coatings.

Summary: Unsatisfactory solubility and recalcitrant condensed structures of isolated lignins (technical lignins) severely limit their processability. Understanding the structural and physicochemical properties of isolated lignins is crucial for explaining their performance in solubilization and further depolymerization. This study investigated the solubilization and depolymerization of organosolv lignins from three different sources. Solubility tests were conducted in six organic solvents, and solubilization behavior was described based on structural properties and investigated under different conditions. Strong structural correlations between parent lignin/subfractions and depolymerized lignin oils were derived.

Summary: The study investigated the effectiveness of copper and iron as alternative reducing agents in the leaching of lithium-ion batteries, and the impact of added H2O2. It was found that aluminum was more efficient than copper in reducing Fe3+ to Fe2+, although copper exhibited a faster rate of iron reduction. The presence of H2O2 led to rapid oxidation of ferrous iron and copper, depleting all reducing agents.

Summary: The HCl gas treatment on Scots pine wood resulted in a well-preserved cellular structure, with higher initial moisture content leading to more degradation of hemicellulose. Interestingly, the hydrogen-deuterium exchange technique showed an increase in accessible OH group concentration despite the loss in hemicellulose. The HCl gas treatment also reduced the concentration of absorbed D2O molecules.

Summary: One way to address the increasing demand for metals and the depletion of high-grade raw materials is through innovative methods of metal recovery. Electrochemical recovery, specifically the combination of electrodeposition and redox replacement processes, has shown promise in efficiently recovering precious metals from underutilized secondary raw materials and hydrometallurgical solutions. This technology allows for the controllable preparation of metal coatings, nanoparticles, and functional surfaces, indicating its potential to alleviate material scarcity. In this review, we analyze the progress and future prospects of electrochemical recovery for metal recovery and the creation of high-value-added materials, including energy efficiency and sustainable materials.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
