Abstract ：
Valorization of lignin is essential for establishing a profitable biorefining industry, yet its efficiency is critically constrained by lignin condensation. Understanding lignin condensation mechanisms and developing effective strategies to inhibit condensation have emerged as a global research imperative. Despite several successful practices in stabilizing the α carbon position of lignin under mild temperatures, a mechanistic understanding of lignin condensation under high temperatures and the corresponding strategy for preventing such condensation remain lacking. Herein, using monophenol as a probe molecule to capture reactive lignin fragments produced under high-temperature treatments, we unveil a novel condensation pathway involving the Cγ-position, which arises from the nucleophilic reaction of the Cγ-position and aromatic rings of lignin. We further demonstrated that phenol, serving as both a radical scavenger and a competitive nucleophilic reactant (vs. lignin aromatic rings), could suppress Cγ-condensation reactions among lignin fragments and, meanwhile, enable the production of novel lignin-derived bisphenols (1,3-diaryl propanes) with a molar yield of 35.2% (mass yield of 45.9 wt %) from eucalyptus feedstock. The mechanistic finding represents a significant advance in lignin chemistry and enables the manipulation of lignin condensation pathways in a wider temperature range for the production of valuable bisphenols (1,1-diaryl propane, 1,2-diaryl propane, and 1,3-diaryl propane), which can serve as precursors for synthesizing biobased polymers and sustainable aviation fuels. © 2025 The Author(s)

Abstract ：
Elastomer-based electronics have the potential to maintain both electrochemical conductivity and mechanical properties simultaneously, paving the way for the development of stretchable sensors. However, creating sensors that are extremely stretchable, wearable, and highly sensitive remains a significant challenge. In this work, we present a novel fully bio-based multifunctional polymer (FPL/PTA) designed using thioctic acid (TA) and formaldehyde-protected lignin (FPL). The FPL serves as both a cross-linking agent and a free radical quenching agent. The FPL/PTA features an adaptive polymer network cross-linked by dynamic covalent disulfide bonds and enhanced by multiple non-covalent interactions. This unique structure imparts the material with stretchability, self-healing properties, hydrophobicity, swelling resistance, self-adhesion, and fully recyclable, degradable characteristics. In addition, the simple preparation route, multiple functions, and green characteristics give the elastomer and choline chloride combination as a strain sensor. The sensor exhibits exceptional sensitivity to strain, repeatability, and durability, enabling it to monitor a wide range of human movements, including joint articulation, speech, and swallowing. We believe that the overall performance and feasibility of manufacturing the developed FPL/PTA marks it as a promising multifunctional strain sensor for applications in flexible wearable electronic devices and humanoid robots.

Abstract ：
The simultaneous degradation and valorization of the most abundant renewable aromatic lignin provides significant benefits for synthesizing complex N-containing aromatic products, which are used in various applications ranging from pharmaceuticals to materials. Therefore, broadening the range of N-containing aromatic products derived from lignin is one of the key objectives in fulfilling future biorefinery and green chemistry needs. Enormous research efforts have been directed toward lignin depolymerization since the structural characterization of lignin has become increasingly understood. Over the past decade, significant progress has been made in N-mediated degradation strategies utilizing lignin models and extracts as raw materials. This review focuses on various activation strategies for cleaving the lignin C-C/C-O bonds while forming new C-C/C-N bonds in the presence of transition metal and metal-free catalysts. Additionally, insights into the fundamentals of reaction control, understanding reaction pathways, and their applications in the synthesis of active pharmaceutical ingredients and functionalized materials are discussed.

Abstract ：
High-density fuel additives are important for heavy transportation. Production of high-density fuel additives from renewable resources has been receiving increasing attention in recent years. Despite the progress in the depolymerization of lignin, cellulose, and hemicelluloses, there are limited studies on integrating lignin and carbohydrates to make value-added products. Here we design a route to synthesize high-density fuel additives with lignin-derived monophenolics and carbohydrate-derived furanics. We performed Bronsted base-catalyzed C-C coupling of phenolics and furanics followed by hydrodeoxygenation catalyzed by a synthesized Ir-ReOx/SiO2 catalyst. Under optimized reaction conditions, the coupling product of phenolics and furanics, bicyclic furyl phenyl precursors, reached a yield of over 90%, and was further hydrodeoxygenated to bicyclohexyl alkanes with a yield of over 98%. The current two-step strategy demonstrates high-selectivity of preparing high-density hydrocarbon fuels from lignocelluloses and provides a possible way to utilize all components of lignocellulosic biomass in an integrated upgrading pathway. High-density bicyclohexyl hydrocarbon fuel additives were selectively synthesized from lignin-derived monophenolics and carbohydrate-derived furanics.

Abstract ：
Enzymatic hydrolysis of cellulose in lignocelluloses exhibits low efficiency due to low cellulose accessibility and adverse lignin effects. By using phenylsulfonic acid pretreatment to improve cellulose accessibility, we have developed several new plant proteins such as corn germ and green rapeseed proteins that extracted from inexpensive defatted meals as lignin-blockers. For pretreated lignocellulosic substrates with high cellulose accessibility, such plant proteins could effectively overcome negative lignin effects and achieve robust cellulose enzymatic conversion (88-97 %) at a low cellulase loading of 5 FPU/g glucan. To reach the same level of cellulose enzymatic conversion, adding corn germ protein could save cellulase loading by 3.6 times as compared to those without lignin-blockers. But these plant proteins showed insignificant promotion effects on substrates with low cellulose accessibility. Overall, this study coupled high cellulose-accessible substrates and efficient ligninblockers to synergistically improve the profitability of lignocellulosic biorefinery.

Abstract ：
Lignin is a phenolic polymer, making it a sustainable alternative to phenol for synthesizing lignin-phenol-formaldehyde (LPF) adhesives. However, technical lignins produced in pulping or biorefining processes are generally highly condensed and have low reactivity, limiting their uses in synthesizing phenolic-based adhesives. Herein, we report a two-step strategy to produce lignin-based wood adhesives with industrially available technical lignins through hydrodeoxygenation followed by acid-mediated methylolation of aromatic C2/6 positions to improve the flowability, water resistance, and crosslinking ability of lignins. We demonstrated that this biobased lignin-formaldehyde adhesive had a lighter color and far better adhesion performance compared to traditional LPF resins prepared from base-mediated methylolation of lignins. Mechanistic investigation suggests that the chemical crosslinking of methylolated lignin to form diarylmethane structures and the physical interlocking interaction at the interfaces of wood veneers contribute to the strength of plywood. A biobased lignin-formaldehyde (LF) adhesive was synthesized from industrially available technical lignins through hydrodeoxygenation followed by acid-mediated methylolation of aromatic C2/C6 positions.
