Cellulosic biomass, as the most abundant renewable resource on Earth, holds great potential for achieving carbon neutrality through efficient valorization, where its hydrolysis to glucose represents a critical initial step. Conventional methods relying on homogeneous acids face limitations such as poor catalyst recycling and significant environmental issues. Carbon-based solid acids (CSAs) for cellulose hydrolysis have emerged as promising alternative, yet, their synthesis often requires high-temperature calcination to construct stable aromatic frameworks, leading to complex and energy-intensive processes. In this study, we propose a novel approach of utilizing the inherent aromatic structure of lignite for synthesizing lignite-derived solid acids (LSAs). We found that lignite was successfully sulfonated directly at low temperature without prior calcination. The synthesized LSAs which possess abundant sulfonic and weak acid sites, proved rapid and efficient hydrolysis of cellulose, resulting in high glucose yield of 57.4 % in just 45 min at 190 °C. In situ Fourier-transform infrared (FTIR) analysis further revealed the weakening of hydrogen bonds and cleavage of glycosidic bonds in cellulose facilitated by LSAs. This work provides a sustainable and low-carbon way for the integrated valorization of lignite and cellulosic biomass.

To overcome the limitations of deformable foods with a single deformation mode and an uncontrollable final shape, this study constructed a salt-responsive shape memory emulsion gel (SMEG) using starch and chitosan (CS), introducing programmable deformation behavior into deformable food systems. The results indicate that at a CS concentration of 2.0% (m/v, CS (2.0)), the gel exhibits a dense and uniform three-dimensional network structure. It can be bent into a spiral shape and fully recovers its original shape after the external force is removed, without wrinkles or cracks, demonstrating good flexibility. This provides the essential physical foundation for its shape memory behavior. CS (2.0) can efficiently fix temporary shapes in NaCl solution (approximately 100% shape memory rate) and fully recover to its original shape in deionized water (approximately 100% recovery rate), while allowing autonomous definition of multiple temporary shapes. Systematic studies using rheology, microstructural observations (SEM, CLSM), and characterization of intermolecular interactions (FTIR) indicate that during the shape fixing stage, enhanced hydrogen bonding densify the polymer network; during the recovery stage, deionized water removes salt ions and disrupts temporary hydrogen bonds, driving network expansion and shape recovery. The reversible phase of CS (2.0) corresponds to a temporary physical crosslinking state formed between CS and NaCl, fixing the temporary shape, while hydrogen bonds act as the main noncovalent interactions driving shape memory recovery. This study provides new theoretical guidance for the design of food hydrogels with controllable shape memory properties.

Systematic comparison of liquid, solid, and semi-solid HM-EVs preservation. • Trehalose/Pluronic® F-68 preserves HM-EVs non‑cryogenically, matching or exceeding commercial products. • Trehalose/Pluronic® F‑68/mannitol lyophilizates improve ambient thermal stability and cargo retention. • Alginate‑starch hydrogels achieve high encapsulation and short‑term HM‑EVs protection. Long-term preservation remains a major challenge for the practical application of extracellular vesicles (EVs). Although various EVs preservation approaches have been reported, systematic comparisons among different physical-state formulations under standardized conditions remain limited, particularly for human milk-derived EVs (HM-EVs). Here, liquid, lyophilized powder (solid), and hydrogel (semi-solid) formulations were developed and systematically evaluated using HM-EVs from the same source. Preservation performance was compared with commercial products through analyses of particle integrity, cargo retention, and storage stability at 4 °C and 25 °C for up to 3 months. The trehalose/Pluronic® F-68 liquid formulation showed superior room-temperature stability, while the trehalose/Pluronic® F-68/mannitol lyophilized formulation effectively preserved EVs structure during short-term ambient storage. The hydrogel provided a protective microenvironment suitable for short-term applications. Overall, this study establishes a cross-format preservation framework for HM-EVs and supports their broader applications in functional foods and biomedicine.

Native starch is difficult to use directly for microcapsule preparation due to its strong hydrophilicity, poor emulsification capacity, and large particle size. This study provides a novel strategy for developing essential oil-loaded microcapsules using Pickering emulsions stabilized by octenyl succinic anhydride (OSA) modified starch nanocrystals (SNCs). The SNCs were prepared via acid hydrolysis of corn starch and further modified with different amounts (3%, 6%, and 12% w /w) of OSA. The SNCs and OSA-modified SNCs (OSNCs) were used to encapsulate cinnamon essential oil (CEO) via interfacial crosslinking in Pickering emulsions, where SNCs/OSNCs (aqueous phase) served as the wall material and isophorone diisocyanate (oil phase) as the cross-linker. The resulting microcapsules (CEO@SNCs, CEO@3%OSNCs, CEO@6%OSNCs, CEO@12%OSNCs) were characterized on physicochemical properties. All OSNC-based microcapsules exhibited superior performance, featuring smaller particle sizes (around 600 nm vs. 2960 nm for CEO@SNCs), higher CEO loading capacity (about 90% compared to 72% for CEO@SNCs), and enhanced long-term stability across a broad temperature range (4–54 °C). Microencapsulation notably improved the functional performance of CEO. In particular, the CEO@6%OSNCs microcapsules demonstrated a release profile consistent with the first-order kinetic model, indicating sustained release behavior, along with effective antioxidant activity and enhanced antifungal efficacy (against B. cinerea and R. stolonifer ).

Proton-conducting ceramics have emerged as a transformative solution for next-generation solid oxide fuel cells for their superior protonic conductivity and high fuel efficiency at intermediate-to-low temperatures. Cobalt-based perovskite oxides stand out as the dominant cathode materials for proton-conducting ceramic fuel cells (PCFCs) due to their unparalleled oxygen reduction reaction activity. However, their implementation is constrained by limited natural reserves and high production costs. To address these challenges, we developed a series of cobalt-free BaFe0.8Zr0.2–xGdxO3−δ (BFZGx, x = 0–0.20) cathodes for low-cost PCFCs. Gd doping simultaneously enhanced the oxygen vacancy concentration and proton hydration capacity while also boosting the total conductivity, with an optimal doping amount of 0.1. Electrochemical evaluations demonstrate the outstanding performance of the BFZGx electrodes, with BaFe0.8Zr0.1Gd0.1O3−δ achieving a 1.93-fold power density compared to the undoped counterpart. This work establishes Gd-doped BaFe0.8Zr0.2O3−δ perovskites as promising high-performance and cost-effective cathode materials for PCFCs.

BACKGROUND In the past 25 years, bed bugs ( Cimex lectularius L. and Cimex hemipterus (F.)) have resurged as common ectoparasites around the world. Effective monitoring is a key to effective bed bug management. Among the various methods used for monitoring bed bugs, installing pitfall-style traps is considered the most reliable. However, there is relatively little research on the characteristics of trap design associated with trapping effectiveness. In this study, we evaluated the effect of diameter, height, color, and anti-escape barrier treatment on trap efficiency for monitoring C. hemipterus . RESULTS Inverted dog bowls were more effective than ClimbUp interceptors in trapping C. hemipterus . The higher the height of the dog bowl, the better the trapping efficiency for C. hemipterus. Inverted dog bowls covered with blue or red tape captured the most C. hemipterus , followed by those with black tape, and green or yellow tape, and the inverted dog bowls covered with white tape captured the least number of C. hemipterus . Fluoropolymer resin, talcum powder, and diatomaceous earth dust coated on the inner walls of the inverted dog bowl completely prevented bed bugs from escaping. Applying talcum powder and diatomaceous earth dust to the inner walls of traps also had a significant bed bug killing effect. CONCLUSION The height and exterior wall's color, as well as the anti-escape barrier treatment coated on the inner walls, are key factors affecting the pitfall-style trap's effectiveness in trapping C. hemipterus . © 2026 Society of Chemical Industry.

A straightforward yet sensitive dual-signal strategy was developed for the detection of melatonin (MT), based on the fluorescence properties and peroxidase-like activity of zinc‑nitrogen co-doped carbon dots (Zn,N-CDs). Through hydrogen bonding, electron transfer, as well as coordination interactions with MT, Zn,N-CDs undergo fluorescence quenching driven by the synergistic effects of static and dynamic mechanisms. Meanwhile, the generated singlet oxygen oxidizes 3,3′,5,5′-tetramethylbenzidine (TMB) into the blue-colored oxidized product (oxTMB), thus producing a ‘triggered’ dual-signal response. This platform enables simultaneous fluorescence and colorimetric analyses, offering wide linear ranges (fluorescence: 2–600 μM; colorimetry: 5–500 μM) and remarkably low detection limits (0.020 μM and 0.999 μM, respectively). Furthermore, the method exhibits excellent selectivity and has been successfully applied to pharmaceutical sample analysis, highlighting its promise for visual quality monitoring of relevant products.

Cognitive impairment is considered as a neurological deficit, which affects millions of people worldwide. Docosahexaenoic acid (DHA), an essential part of brain cell membranes, is crucial for supporting neural communication and preventing cognitive decline. To address this concern, emulsion fillers comprising salmon myofibrillar protein (SMP), Konjac glucomannan (KGM), and octenyl succinic anhydride (OSA)-starch were used. An DHA-loaded emulsion gel stabilized by OSA-satrch through the modulation of the oil volume fraction was developed to strengthen the structure of SMP gels. The stabilization by the SMP-KGM gel and OSA-starch SMP–KGM (OSA-SMPG) promoted the formation of a compact three-dimensional network structure in the emulsion gel, which resulted in an increased storage modulus, enhanced viscoelastic properties, and good thixotropic behavior. DHA-loaded OSA-SMPG emulsion gel alleviated organ atrophy in mice and reduced escape latency by 48% while improving learning and memory abilities. The total cholesterol level in mouse serum decreased by 32%. In addition, OSA-SMPG alleviated the oxidative stress induced by D-galactose in mice, increased the body’s antioxidant defenses, and increased superoxide dismutase levels in brain tissue by 43%. These findings suggest that promising prospects and potential for nutritional intervention in individuals with cognitive impairment are offered by OSA-SMPG.

The practical application of direct-ammonia protonic ceramic fuel cells (DA-PCFCs) is constrained by the sluggish decomposition of ammonia and the structural degradation of conventional Ni-based anodes. Herein, a multifunctional anode is developed by depositing a Sr 2 Fe 1.4 Ru 0.1 Mo 0.5 O 6-δ (SFRM) perovskite catalytic layer onto a Ni-BaZr 0.1 Ce 0.7 Y 0.1 Yb 0.1 O 3-δ cermet. Under operating conditions, this layer enables the in-situ exsolution of uniformly dispersed and sintering-resistant Ru–Fe alloy (RFA) nanoparticles, thereby creating a stable and catalytically active interface. The SFRM-modified single cell achieves peak power densities of 1.33 cm –2 and 1.02 cm –2 at 700 °C in H 2 and NH 3 , respectively, with the NH 3 -fueled performance representing a 15.9 % improvement over the unmodified single cell. Moreover, the cell exhibits excellent durability, operating stably for over 100 h in NH 3 . Combined experimental and density functional theory calculations reveal that the exsolved RFA nanoparticles not only lower the energy barrier for NH 3 dehydrogenation but also, via strong metal-support interaction, regulate interfacial charge transfer and suppress Ni 0 coarsening. This strategy successfully decouples high catalytic activity from long-term stability, providing an effective pathway for durable, high-performance DA-PCFCs.

Under the dual challenges of plastic-driven environmental pollution and global food insecurity, there exists an urgent demand for sustainable packaging solutions capable of extending produce shelf life. Cellulose nanofibers (CNF) and chitosan (CS) are promising bio-based materials; however, their susceptibility to performance loss in high-humidity environments and their lack of intrinsic heat-sealing capability limit practical applications. Herein, an asymmetric bilayer CNF/CS film crosslinked with genipin is introduced to effectively address the performance degradation under humid conditions. The film is hydrophobically modified with octanoic acid (OA), achieving an optimal balance of high transparency (visible-light transmittance >80%) and hydrophobicity (contact angle ≈ 110°). The inner layer, comprising thermoplastic starch (TPS) plasticized with polyvinyl alcohol (PVA) and blended with a thymol/octanoic acid deep eutectic solvent (DES), affords low-temperature processability and heat-seal performance (seal strength = 19.9 N / 15 mm) alongside potent antibacterial and antioxidant activity (inhibition > 98% against E. coli and S. aureus ). In strawberry and blueberry preservation trials, the resulting film completely suppresses mold growth within 5 days, with only 8% weight loss, and exhibits over 85% biodegradation in soil within 30 days. This bilayer design provides a new solution for developing high-performance, eco-friendly food packaging materials.

An increasing interest in utilizing biomass resources to develop bioplastics, aiming to mitigate the environmental and energy issues resulting from the use of petroleum-based plastics. However, bioplastics that suffering from poor interface bonding and hydrophilicity of the feedstock usually exhibit inadequate mechanical properties, water stability and functionality, which hinder their practical applications. Herein, a simple and effective strategy was proposed to develop high-performance starch-based bioplastics with thermoplastic by 2,2,6,6-tetramethylpiperidine 1-oxy-oxidized cellulose nanofibers and different modified starch fillers coupled with chemical cross-linking reinforcement. Due to the full utilization of the advantages of each component, outstanding interface bonding and rich chemical cross-linking, all the obtained modified starch-based bioplastics demonstrated excellent mechanical properties (up to 20.52 MPa) and superior water stability. Besides, the starch-based bioplastics could be reused after dissolution-regeneration, and completely biodegradable after disposal. At the same time, the starch-based bioplastics exhibited remarkable heat-sealing properties, which provided more convenient possibility of producing packaging materials for bioplastics used in different fields.
