Chicken head gelatin enabled high-value utilization of poultry by-products. • Curcumin improved multiple properties of gelatin-based composite films. • Curcumin exerted antibacterial activity via release and contact dual mechanisms. • The optimized film inhibited quality deterioration of refrigerated chicken breast. • Selected films prolonged shelf life from 4 days to 6 and 8 days versus the control. To address the spoilage susceptibility of poultry products during refrigerated storage, as well as the environmental limitations of conventional non-degradable packaging films and the single functionality of existing gelatin films with insufficient antioxidant and antibacterial activities, this study utilized chicken heads, a by-product of poultry processing, for gelatin extraction. Curcumin was incorporated as a natural active ingredient to develop an active packaging film for extending the shelf life of refrigerated chicken breast. The effects of different curcumin loadings (0, 5, 10, 15, and 20 g/kg) on the packaging and functional properties of gelatin-based composite films were investigated to determine the optimal concentration. The results indicated that films with 20 g/kg curcumin loading exhibited optimal performance, with significantly enhanced antioxidant (DPPH and ABTS radical scavenging rates were 87.95% and 95.21%, respectively) and antibacterial activities (bactericidal rates against Escherichia coli and Staphylococcus aureus were 74.43% and 75.35%, respectively). Under storage at 4 °C, films at this concentration effectively inhibited microbial growth, delayed protein decomposition and lipid oxidation, and extended the shelf life from 4 to 8 d. This study achieves high-value utilization of poultry processing by-products and provides a novel, green and efficient packaging solution for the refrigerated preservation of chicken breast.

Extraction of Paeoniae Radix Rubra polysaccharide (PRRP). • Firstly, the PRRP was extracted by Natural Deep Eutectic Solvent (NADES). • Firstly, the PRRP was extracted by ChCl-CA (1.5, 3:2) with 40% ( w / w ) water. • AGREEprep and BAGI confirmed ChCl-CA’s greenness: polysaccharide yield >9%, solvent recovery >80%. • Firstly, the neuroprotective activity of PRRP in Parkinson's disease was evaluated. Firstly, natural deep eutectic solvents (NADES) were used to extract polysaccharides from Paeoniae Radix Rubra (PRR). Using polysaccharide yield and neuroprotective cell activity as evaluation criteria, a solvent composed of 40% ( w / w ) water, choline chloride (ChCl), and citric acid (CA) was selected as the optimal solvent. It exhibited low viscosity, high surface tension, moderate polarity, and strong acidity. Fourier-transform infrared (FT-IR) spectra of the ChCl-CA confirmed the formation of hydrogen bonding. Response surface methodology (RSM) optimized conditions: molar ratio: 1.5 (3:2), extraction temperature: 60 °C, extraction duration: 64 min, solvent-solid ratio: 36 mL·g −1 , the polysaccharide yield reached 16.74%, which was 1.89 times that of the hot water extraction, and the SH-SY5Y cell activity in the methyl-4-phenylpyridinium (MPP + )-induced PD model was 86.86%. The obtained PRR polysaccharides (PRRP) were further characterized, with protein content of 5.23% and uronic acid content of 19.09%. PRRP was mainly composed of arabinose, glucose, and galacturonic acid. Its molecular weights are 73.381, 11.475, and 3.539 kDa. PRRP was characterized via Ultraviolet-Visible (UV–Vis) and FT-IR spectroscopy, confirming typical polysaccharide structures. After 6 cycles, the polysaccharide yield of recycled NADES decreased from 16.26% to 9.22% in the final extraction, a 43.30% decrease. Two classical green evaluation models quantitatively confirmed the process's environmental friendliness. In addition, in vitro experiments showed that PRRP could increase dopamine (DA) and tyrosine hydroxylase (TH) levels, reduce lactate dehydrogenase (LDH) release, and decrease α -synuclein ( α -Syn) accumulation. This study highlights the efficiency of ChCl-CA as a green extractant and reveals the neuroprotective effect of PRRP.

A soft-chitosan interface was developed for composite flexible electrodes. • The interface bridged SEBS and PEDOT:PSS through multiple interactions. • The fabricated electrode remained stable under extreme and cyclic tensile strain. Flexible conductive electrodes used for wearable electrophysiological sensing are frequently limited by interfacial instability arising from insufficient intercomponent interaction and elastic mismatch under repeated mechanical deformation. In this study, a soft-chitosan interfacial system was introduced into styrene-ethylene-butylene-styrene (SEBS)/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) composite electrodes to enhance structural integrity and electrical stability during tensile loading. Glycerol and Tween 80 were employed to maintain chitosan chains in a soft and deformable state, allowing the interfacial layer to penetrate the porous SEBS substrate through capillary action and form rivet-like anchoring structures. Simultaneously, hydrogen bonding and electrostatic attraction between the interfacial layer and the PEDOT conductive layer established effective interfacial coupling. Benefiting from this cooperative interface design, the resulting composite electrode exhibited stable conductivity retention under large tensile strain and cyclic stretching conditions. In addition, the electrode enabled reliable electromyographic (EMG) signal monitoring of the forearm and masseter muscles with stable waveform acquisition during motion. These results demonstrate the potential of the developed electrode for wearable electrophysiological sensing applications. This work provides an interfacial engineering strategy for stretchable conductive electrodes requiring stable electrical performance under mechanical deformation.

A Hofmann-degraded HTO/CMC/PVA composite film solves powdered HTO’s solid-liquid separation issue via a dense cross-linked network. • Protonated primary amine groups boost lithium selectivity by nearly twofold through the Donnan exclusion effect. • Superior lithium adsorption in real samples, retaining 91.3% capacity after six adsorption-desorption cycles. Rapid global new energy development fuels explosive lithium demand, with efficient purification of salt lake brine and battery leachate a research hotspot. Liquid-phase lithium recovery is severely hindered by coexisting metal ions with ionic radii similar to lithium, leading to high system complexity. Although powdered H 2 TiO 3 (HTO) lithium ion sieves have inherent advantages of stable structure and excellent adsorption capacity, they face critical technical bottlenecks including low solid-liquid separation efficiency and easy co-adsorption by high-valence interfering ions. To solve these problems, this study modified polyacrylamide (PAM) through Hofmann degradation reaction to introduce primary amine groups, and further compounded modified PAM with carboxymethylcellulose (CMC) and polyvinyl alcohol (PVA) to prepare an HTO-loaded CMC/PVA/PAM composite adsorption film. The film forms a dense cross-linked network via intermolecular hydrogen bonds among the three polymers, fundamentally solving the solid-liquid separation issue of powdered HTO. In an alkaline adsorption environment (pH < 10.5), primary amine groups on modified PAM are protonated to form positive charge sites, which exert the Donnan exclusion effect through electrostatic repulsion to effectively inhibit co-adsorption of magnesium, cobalt, manganese and nickel ions, raising the lithium selective separation efficiency of HTO/CPP2 by nearly twofold compared with HTO/CP. The film showed outstanding specific adsorption performance in actual Da Qaidam Salt Lake water samples and waste battery residue leachate, with good cycling stability that retains 91.3% of the initial adsorption capacity after six cycles. This research thus provides a novel and feasible technical solution for the integrated green extraction of high-purity lithium from two typical complex lithium-containing systems.

TDESs simultaneously enhance CALB activity, stability, and DAG selectivity. • ChCl:Gly:U (1,1:1) shows optimal catalytic performance. • Hydrogen-bond networks regulate CALB conformation and catalytic function. • DESs enable high-yield DAG synthesis with reduced by-product formation. Solvent engineering plays a crucial role in improving lipase performance in non-aqueous biocatalytic systems, particularly for the efficient and selective production of functional lipids. In this study, choline chloride-glycerol-urea ternary deep eutectic solvents (TDESs) were constructed to regulate the catalytic behavior of Candida antarctica lipase B (CALB), and the relationships between solvent physicochemical properties, enzyme conformation, and catalytic performance were systematically evaluated through enzymatic assays, fluorescence spectroscopy, and molecular dynamics simulations. Compared with binary DES and solvent free systems, TDESs exhibited lower water activity, tunable viscosity, and strengthened hydrogen-bonding networks, providing a more stable microenvironment for CALB. The optimal ChCl:Gly:U (1:1:1) system enhanced catalytic activity by 2.8-fold and retained over 80% residual activity after thermal treatment. Simulation results indicated reduced RMSD, RMSF, and SASA values, suggesting improved structural compactness. Subtle changes in interaction behavior within the catalytic triad (Ser105-His224-Asp187) were also observed, indicating localized modulation of active-site dynamics that may contribute to enhanced flexibility. In esterification, ChCl:Gly:U increased DAG content to 61% and reduced MAG content to <15% (vs. 45% DAG and 32% MAG in the solvent free system). In addition, the selectivity of DAG formation in TDES systems increased significantly from 57.66% to 73.61%. These findings demonstrate that rationally designed TDESs effectively enhance CALB activity, stability, and DAG selectivity, providing a feasible and sustainable strategy for enzymatic lipid modification.

Eutectogels hold considerable promise for applications in flexible electronics, soft robotics, and protective systems owing to their combination of the environmental stability of deep eutectic solvents and the mechanical robustness of polymer networks. However, predominantly weak intermolecular interactions among polymer chains within eutectogels restrict their mechanical performance, making it challenging to simultaneously achieve high strength and high toughness. Herein, we propose an inorganic ionic polymerization-anchored polymer network (IIP-APN) strategy to construct ultrastrong and ultratough eutectogels. Specifically, calcium phosphate oligomers (CPO) are incorporated into the polyvinyl alcohol (PVA) chain network to serve as nanoanchors. Through inorganic ionic polymerization, hydroxyapatite nanorivets are generated to anchor PVA chains, forming a hierarchically integrated organic–inorganic composite network. This unique riveting network structure imparts record-breaking ultrahigh toughness (696.4 ± 119.1 MJ m − 3 ) and high strength (58.02 ± 3.87 MPa) to the resulting PVA/CPO eutectogels, significantly surpassing existing gel materials. Moreover, the PVA/CPO eutectogels demonstrate excellent energy absorption and dissipation, outstanding fatigue resistance over 8000 cycles, and the capacity for damage repair via secondary inorganic ionic polymerization. Consequently, PVA/CPO eutectogels exhibit significant potential for technological applications. The proposed IIP-APN strategy provides a powerful platform for the design and development of high-performance gel materials.

Membranes with excellent chlorine resistance are required for stable operation and long service life. Traditional polyamide (PA) nanofiltration (NF) membranes typically suffer from inadequate chlorine resistance. To overcome this critical challenge and the long-standing problem of insufficient permeability, a novel polyesteramide (PEA) NF membrane was fabricated. Specifically, naringin (NG), a naturally occurring polyphenol rich in hydroxyl groups, was introduced as a co-monomer with piperazine (PIP) in the aqueous phase for interfacial polymerization with trimesoyl chloride (TMC) in the organic phase. The chlorine-susceptible amide groups were partially substituted by intrinsically chlorine-resistant ester groups in the fabricated PEA membrane. As a result, the chlorine resistance of the PEA membrane was greatly enhanced, with Na 2 SO 4 rejection remaining above 93 % after exposure to 20,000 ppm h of free chlorine. The resulting PEA membrane exhibited reduced surface roughness and selective-layer thickness, coupled with a slight increase in pore size and free volume fraction, which was attributed to intermolecular interactions between NG and PIP in the aqueous phase. Consequently, the PEA membrane demonstrated a water flux approximately twice that of the PA membrane, while maintaining a high Na 2 SO 4 rejection rate of 99 % and rejecting more than 98 % of various antibiotics (e.g., cephalosporins and tetracyclines). Furthermore, the PEA membrane exhibited favorable antifouling performance, satisfactory anti-swelling property, and filtration stability under various conditions.

Coupling glycerol oxidation with hydrogen production offers a promising approach to reducing the energy consumption of hydrogen production and upgrading biomass. However, the catalytic performance is often limited by insufficient interfacial charge transfer and poorly defined active sites. Herein, we report a sulfur-modulated NiFe layered double hydroxide catalyst integrated with a Metal-organic frameworks (MOF)-derived Cu framework on nickel foam, in which well-defined heterogeneous interfaces are deliberately constructed to regulate the local electronic structure and catalytic microenvironment. Sulfur incorporation reconstructs the metal coordination environment and induces electron redistribution. As a result, the catalyst exhibits outstanding glycerol oxidation performance toward formate with high selectivity over a broad potential window, along with remarkable durability at high current densities. In situ Fourier transform infrared (FTIR) spectroscopy identifies the key intermediates involved in glycerol oxidation, while density functional theory (DFT) calculations reveal that sulfur-induced electronic coupling lowers the reaction energy barrier and facilitates charge transfer.

This study optimized the extraction of polyphenols from Dendrobium residue using a natural deep eutectic solvent (NADES). A Box-Behnken design determined the optimal conditions: a choline chloride to glucose molar ratio of 2.4:1, solid-to-solvent ratio of 1:61 g/mL, water content of 35.7%, temperature of 80 °C, and duration of 120 minutes. This yielded a polyphenol content of 1.381 ± 0.071%, which was 2.93 to 38.36 times higher than conventional organic solvent methods. Fourier transform infrared (FTIR) spectroscopy was used to characterize the hydrogen bonding changes in the NADES system, while scanning electron microscopy (SEM) was employed to examine the morphological differences of Dendrobium residues before and after extraction treatment. Ten compounds were identified from the NADES extract, namely Prunin, Schaftoside, Apigenin-6,8-di-C-α-l-arabinopyranoside, Batatasin III, Moscatilin, Dihydroresveratrol, Hesperetin, Naringenin, Dendrophenol, and Erianin, which exhibited important pharmacological activities. Ultra-performance liquid chromatography(UPLC) analysis revealed a great variety and quantity of polyphenols in the NADES extract. Furthermore, the extract exhibited superior antioxidant activity: at 1.00 mg/mL, DPPH scavenging was 90.615 ± 0.92%, ABTS scavenging was 96.095 ± 0.44%, and FRAP value was 1.048 ± 0.03 mmol/L. These results highlight the green and efficient nature of this NADES-based protocol for industrial applications in food and herb residue processing.

In this study, we explored the therapeutic effects and mechanisms of baicalin (BA) in a dibutyltin dichloride (DBTC)–induced chronic pancreatitis (CP) rat model using metabolomics and network pharmacology. The results showed that BA significantly reduced inflammatory cell infiltration and fibrosis in pancreatic tissues, lowered serum levels of interleukin (IL)-1β, IL-6, tumor necrosis factor-alpha (TNF-α), amylase (AMS), and lipopolysaccharide (LPS) and thereby decreased expression of alpha-smooth muscle actin (α-SMA) and fibronectin (FN) in pancreatic tissues. Metabolomic analyses revealed that BA influences multiple metabolic pathways, including glycerophospholipid and arachidonic acid metabolism, in serum and urine. Network pharmacology identified key targets, such as phospholipase A2 group IVA (PLA2G4A) and transient receptor potential vanilloid 4 (TRPV4), which are primarily involved in IL-17 signaling, as well as other pathways beyond inflammation. Further integrated analysis demonstrated that BA inhibits pancreatic stellate cell activation and reduces pancreatic fibrosis by regulating metabolites, such as arachidonic acid, that act on the PLA2G4A/TRPV4 and transforming growth factor-beta 1 (TGF-β1)/SMAD family member 3 (SMAD3) pathways. Molecular docking studies confirmed that BA binds strongly to these targets. In summary, BA exerts anti-inflammatory and antifibrotic effects through multiple targets and pathways, thereby alleviating the pathological progression of CP.

The reliable joining of graphite and Cu holds significant promise for applications in electronic heat dissipation and sliding electrical contacts. However, the substantial differences in their physicochemical properties, poor wettability, and mismatch in coefficients of thermal expansion often result in low joint strength. In this study, a two-step joining strategy combines surface modification with low-temperature sintering, and this is proposed for fabrication of Cu/graphite joints. First, the graphite surface is modified using an AgCuTi active filler alloy under vacuum conditions. Ti preferentially segregates at and reacts with the graphite interface, leading to the formation of an Ag-Cu eutectic modified layer on the graphite surface. Subsequently, low-temperature joining of the modified graphite to a Cu substrate is achieved via a hot-pressing sintering process using a Ag paste. In the sintered joint, the Ag sintered layer forms sound metallurgical bonds with both the Cu substrate and the graphite-modified layer. When the sintering temperature is 250 °C, the joint exhibits a shear strength of 30 MPa, which is significantly higher than that of a directly brazed joint. This strategy effectively reduces thermal residual stress in the joint during cooling and shifts the failure location from the brittle graphite substrate to the ductile Ag sintered layer, thereby substantially enhancing the mechanical performance.

Due to its high surface polarity and tendency to agglomerate, sepiolite exhibits weak interfacial bonding with the nonpolar natural rubber (NR) matrix, leading to poor mechanical and dynamic properties. This limits the high-value application of natural minerals in high-performance NR composites. In this paper, a hydrogen bond network-enhanced ternary deep eutectic solvent (CGA–DES) was prepared using glycerol and aspartic acid as dual hydrogen bond donors and choline chloride as the hydrogen bond acceptor. The effects of CGA–DES dosage on filler dispersion, vulcanization characteristics, mechanical properties, aging resistance, and dynamic mechanical properties of sepiolite/NR composites were investigated. SEM showed that CGA–DES promoted the dispersion of sepiolite and its interfacial bonding with NR. When 2 phr of CGA–DES were added, the processing flowability of the compound was improved, the vulcanization time was shortened, the mechanical properties and aging resistance were enhanced, and the rolling resistance decreased, resulting in the best overall performance. Compared with the unmodified Sep/NR, the tensile strength, tensile product coefficient, aging coefficient, and DIN abrasion volume of 2 CGA/Sep/NR reached 20.15 MPa, 11801.98, 0.32, and 0.198 cm 3 , which improved by 67%, 82%, 78%, and 21%, respectively. Meanwhile, the rolling resistance decreased by 54%, and better dynamic mechanical properties were achieved. Aspartic acid contains both carboxyl and amino functional groups, enabling the formation of an enhanced hydrogen-bonding network with sepiolite and facilitating more effective crosslinking reactions during the vulcanization process. This paper provides a new approach for regulating filler–rubber interfacial interactions by using a bio-based deep eutectic solvent, which is expected to promote the development of high-performance green tires and rubber products. Highlights The deep eutectic solvent was prepared by glycerol, aspartic acid, and choline chloride. The dispersion of sepiolite and its interfacial bonding with rubber were improved. The processing flowability was improved and the rolling resistance was decreased. The tensile strength and aging coefficient were improved by 67% and 78%, respectively.
