Abstract ：
Cellulose acetate (CA) is a versatile biopolymer derivative widely used in consumer products such as cigarette filters, textiles, and plastics. The extensive use of CA-based products generates substantial plastic waste, which can persist in the environment for over a decade due to its low biodegradability, posing serious environmental challenges. Herein, we report a one-step conversion process that transforms CA plastic waste into 5-hydroxymethylfurfural (HMF) while simultaneously recovering acetic acid. By employing AlCl3 as a catalyst in an acetone-water solvent system at 160 degrees C for 50 min, CA exhibited a 53.7 % HMF yield, a threefold increase compared to untreated cellulose, while also achieving a 97.3 % theoretical yield of acetic acid. The HMF yield exceeded 50 % when cigarette filters or CA fabrics were used as substrates. Molecular dynamics simulations revealed that the acetyl groups in CA enhance its coordination with acetone molecules, reducing the probability of protonation at the C1 and C4 oxygen atoms of the CA monomer and thereby suppressing the formation of undesired byproducts. Furthermore, the in-situ regenerated acetic acid actively promotes the HMF production. This study establishes a viable pathway for upcycling CA waste while advancing sustainable management strategies for CA-based plastics, offering a promising solution to mitigate environmental impacts.

Abstract ：
Development of sustainable solvents for biomass biorefining remains a pivotal challenge of green chemistry. This study presented a circular biorefining strategy that valorized hemicelluloses into biobased solvent diformylxylose (DFX; Hansen solubility parameter: 21.4 MPa-1/2) for acetal-protection pretreatment. The DFX-H2O cosolvent system (90/10, w/w), with addition of formaldehyde and HCl, showed a decent yield of acetal-protected lignin (84.7%) and enzymatic conversion of acetal-protected cellulose after deprotection by acid hydrolysis (82.9%). Crucially, hemicelluloses-derived xylose was concurrently converted into additional DFX in situ during pretreatment, sustaining the delignification process. The spent DFX (including newly formed) was effectively recovered by crystallization and the isolated acetal-protected lignin was upgraded to monomers via hydrogenolysis at near-theoretical yields (46.5%). This work demonstrates a self-reinforcing cycle where a biomass component is transformed into the key solvent enabling efficient fractionation.

Abstract ：
Classical production of construction particleboards with high-grade wood and formaldehyde-based binders induces forest depletion and pollution, calling for alternatives. Here, we designed in situ lignin bonding to transform low-grade woods into high-performance and formaldehyde-free particleboards. This method involves the deconstruction of fine wood particles to soften cell walls, eliminating undesirable water-soluble components while preserving lignin, followed by a thermo-compression molding procedure to facilitate the formation of a compact and cross-linked structure within softened wood particles. Results show that particleboard displays high mechanical strength with a rupture modulus of 66.7 MPa and excellent water resistance with a thickness swelling of 2.1%. The performance of particleboards is enhanced by low wood hardness, small particle size, removal of water-soluble fractions, and preservation of lignin. The self-adhesion technique is straightforward, practical, and scalable.

Abstract ：
Piezo-photocatalysis is capable of concerting mechanical vibration into chemical energy, portraying a promising alternative technology for H2O2 production. However, low mechanical energy conversion efficiency and constrained surface active sites hinder its practical application. Herein, ultrathin porous carbon nitride nanosheets with controlled carbon vacancies and oxygen doping (OCN-X, where X represents the calcination temperature) are synthesized by thermal oxidation etching to achieve unprecedented piezo-photocatalytic H2O2 production. The carbon vacancies and oxygen doping cause the formation of asymmetric structure of triazine unit with a strong dipole field, which creates spontaneous polarization field to speed up directional electron transfer to the nitrogen active sites for effective piezo-photocatalysis. Meanwhile, the ultrathin and porous structure formed by hot-oxygen etching enhances the mechanical energy conversion efficiency and collaboratively induces adsorbed oxygen via indirect two-electron oxygen reduction reaction (ORR) transfer pathway to effectively produce H2O2. Consequently, without any co-catalysts, the as-prepared OCN-460 displays record-high piezo-photocatalytic H2O2 production rate of 19.30 mmol g-1 h-1, far outdistancing those previously reported for piezo-photocatalysts. Furthermore, it also still maintains a notable piezo-photocatalytic activity of 2.87 mmol g-1 h-1 in the pure water system. This work offers some new insights for the future design of an effective piezo-photocatalytic H2O2 production system.

Abstract ：
Increasing efforts have been devoted to developing biobased and biodegradable plastics and composites from lignocellulosic biomass. Current bioplastic production entails multiple challenging steps including monomer production from biomass as well as polymer synthesis and modification. Here, we report a practical recombination strategy to transform agricultural residues into moldable cellulose-reinforced lignin (CRL) composites. The strategy involves deconstruction of biomass particles followed by thermo-compression molding of cellulose fibers and lignin mixtures. The resulting CRL composites demonstrated excellent mechanical and thermal properties as well as water, abrasive, and flame resistance. Mechanistic studies reveal that small particle size, removal of water-soluble fractions, as well as reservation of lignin and its cross-linking reactivity have considerably positive effects on preparation of high-quality composite items. These insights offer a versatile strategy for transforming various types of low-grade biomass, such as corn stover, into eco-friendly and potentially biodegradable or compostable composites that can serve as sustainable alternatives to traditional duroplast materials.

Abstract ：
The aviation industry plays a crucial role in global trade and cultural exchange, but it faces significant challenges due to high production cost and environmental impacts. To achieve carbon neutrality, promoting the development of sustainable aviation fuel (SAF) is essential, with projections indicating that 65% of emissions reductions in the aviation industry by 2050 will come from the use of SAF. Lignin, as an abundant renewable resource, has great potential for conversion into aviation fuel components. It can be depolymerized and/or hydrodeoxygenated (HDO) to produce C6-C9 alkanes. However, to produce high-density SAF, lignin monomers need to undergo coupling, alkylation, and transalkylation reactions to extend the carbon chain to C8-C16 precursors, which can then be converted into long-chain alkanes suitable for SAF through HDO reactions. This paper reviews the research progress on synthesis of lignin-based SAF, highlights key synthetic methods, and analyzes how catalyst and reaction conditions affect the synthesis pathways, efficiency, and properties of SAF. Additionally, the obstacles and challenges hindering the development of biomass-based SAFs are discussed to provide theoretical support for future research in this field.

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 ：
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 ：
Flexible hybrid nanogenerators (HNGs) have received significant attention for their potential in harvesting mechanical energy to power portable and miniaturized portable devices. This work presents a method to fabricate flexible, durable and biodegradable electrospun polydopamine@barium titanate/cellulose acetate (PDA@BTO/CA) nanofiber films. This design integrates polydopamine (PDA) and piezoelectric barium titanate (BTO) nanoparticles within a flexible cellulose acetate (CA) matrix to enable self-powered wearable biomonitoring. The inclusion of PDA enhances the physical adhesion between BTO and CA, resulting in a significant 40% increase in voltage output. Notably, the PDA-modified composite PDA@BTO/CA demonstrates remarkable durability over 15,000 cycles and effectively detects a range of human motions (such as fist clenching, wrist bending, elbow movement, walking, running and jumping), transducing them into stable, precise electrical signals. Intriguingly, the hybrid nanogenerator device exhibits robust performance in extreme conditions, including underwater and high or low temperatures, while maintaining its good biodegradability. This work paves the way for advanced self-powered wearable biosensor devices capable of precise and reliable human motion monitoring.

Abstract ：
Nature excels in synthesizing advanced protein adhesives under mild condition, utilizing enzyme catalysis to achieve controllable and adjustable cold-set adhesion. To emulate this natural prowess in synthetic protein adhesives (SPAs), which are often hindered by low reactivity, weak controllability, and poor selectivity, we developed a biomimetic-enzyme-catalysis strategy to successfully construct SPAs with cold-set adhesion function via a facile one-pot method. By employing magnesium oxide (MgO) as a catalyst, the resultant adhesive demonstrated enhanced and versatile adhesion capabilities (1.67/0.98 MPa to wood for dry/wet condition, respectively), with controllable and adjustable adhesion by tailoring crosslinked and catalytic sites. Moreover, this design was applicable to various types of crosslinkers and proteins to create more robust cold-set SPAs. The investigation of the catalysis mechanism has revealed that MgO selectively and controllably interacts with adhesive molecules, effectively lowering the energy barrier necessary for successful molecular crosslinks at room temperature. Together with its demonstrated potential in large-scale and long-term applications, our strategy provides a viable pathway for the eco-friendly and scalable production of high-quality cold-set SPAs that rival natural protein adhesives.
