Abstract ：
Biochar materials, known for their low cost, abundant availability, green environmental protection and renewable nature, are extensively applied across the energy storage sector. However, their structure and inherent limitations of the raw materials greatly reduce their energy storage performance. In this research, we aimed to optimized the structure of Melaleuca leucadendron L. bark activated carbon (BAC) by adjusting the ball milling time and speed. We also explored the optimal composite mass ratio of BAC/polyaniline (PANI) and further enhanced the electrochemical performance of the pseudocapacitive material composite employing in-situ polymerization techniques with ferric chloride doping for PANI. The characterization of BAC/PANI composites was performed through scanning electron microscopy (SEM), nitrogen adsorption-desorption isotherms (BET), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR). The BAC/PANI electrode materials' electrochemical capabilities and supercapacitor functionality were tested using cyclic voltammetry (CV), galvanostatic charge-discharge analysis (GCD), and electrochemical impedance spectroscopy (EIS). The study demonstrated that ball milling not only mended defects in amorphous carbon but also increased crystallinity and oxygen content. Additionally, the presence of PANI contributed nitrogen atoms. The functional groups with oxygen and nitrogen content improved the electrode materials' wettability, which contributed to the pseudo-capacitive effect and subsequently increased electrochemical performance. The BAC/PANI-FeCl3-10 material exhibits a defined capacitance of 414.0 F g-1 at a current density of 0.5 A g-1, and maintained a capacity retention rate of 74.7 % after 5000 cycles, with an energy density output of 5.2 Wh kg-1 at a high-power density of 1872.0 W kg-1. © 2025, The Authors.

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 ：
With the backdrop of the rapid advancement in supercapacitor technology, biomass hydrogel electrolytes have emerged as a prominent research focus. This study systematically optimized critical parameters using a multi-component synergistic strategy, the glycerol (Gl) as an antifreeze agent, to develop a ligninsulfonate (LS) dual-network antifreeze hydrogel suitable for low-temperature-resistant supercapacitors. The P(AA-co-AM)/LS/Al3+/Gl hydrogel exhibited remarkable mechanical properties, with tensile stress reaching 751.01 kPa and strain of 1050 %. The assembled supercapacitor demonstrated a specific capacitance of 244.5 F g−1 at room temperature under a current density of 0.2 A g−1. After 5000 charge-discharge cycles, the capacitance retention rate remained 80.16 %, with a coulombic efficiency exceeding 98.5 %. Moreover, at −80 °C, the hydrogel assembled supercapacitor achieved a specific capacitance of 167.2 F g−1; retaining certain electrochemical performance across various bending angles. This research provides valuable insights into the development of biomaterial-based antifreeze electrolytes for extreme environments. © 2025 Elsevier Ltd

Abstract ：
In this study, a novel diamine 4-(2,6-bis(4-(trifluoromethyl)phenyl)pyridine)phenyl-3,5-diaminobenzoate (FPPAB) containing trifluoromethyl, pyridine, and ester groups was synthesized by a three-step organic reaction. Then, four structures of copolyimides were prepared by a one-step polycondensation reaction using diamine (FPPAB), dianhydride 4,4 '-(hexafluoroisopropyl)diphthalic anhydride (6FDA), and four commercial diamines. The synthesized copolyimides exhibited high thermal stability, with the glass transition temperature (T-g) and 5% loss temperature (T-5%) in the range of 210 degrees C-256 degrees C and 343 degrees C-452 degrees C, respectively, and X-ray diffraction analysis indicated that the copolyimides featured a d-spacing of 4.90-5.57 & Aring;. They also showed excellent solubility in both high and low boiling point organic solvents. Furthermore, the membranes not only had outstanding optical properties (wavelength range of 80% transmittance = 378-454 nm) but also had excellent hydrophobicity (water contact angle > 91.96 degrees). Notably, the copolyimide membrane with a fluorene structure showed the highest gas permeability (P(He) = 46.27, P(CO2) = 21.06, P(N-2) = 1.57 barrer) and favorable selectivity (alpha(He/N-2) = 29.55, alpha(CO2/N-2) = 13.69). This membrane also exhibited the largest fractional free volume (FFV). Overall, the prepared copolyimides exhibited a well-balanced combination of properties, particularly in gas separation performance, indicating that the properties of copolyimides could be effectively optimized by adjusting the structure of monomers.

Abstract ：
Cellulose-based hydrogels are promising materials for constructing flexible supercapacitors and energy storage devices due to their environmental sustainability and resource renewability. However, preparing cellulose-based hydrogel electrolytes with super flexibility, high conductivity, and high specific capacitance for practical applications is still challenging. Herein, an adhesive, antibacterial, conductive zwitterionic cellulose nanofibersreinforced poly(sulfobetaine methacrylate-acrylic acid-acrylamide (ZCNF/PSAA) composite hydrogel was fabricated by a blue light-triggered free radical polymerization of 2-methacryloyloxy ethyl dimethyl-3sulfopropyl ammonium hydroxide (SBMA), acrylic acid (AA), acryl amide (AM), dopamine methacrylamide (DMA) and zwitterionic cellulose nanofibers (ZCNF). The prepared hydrogel exhibited excellent mechanical properties with tensile strength of 0.17 MPa, compressive strength of 0.87 MPa, and shear strength of 1.25 MPa, respectively. The zwitterionic groups significantly enhanced the hydrogel's conductivity (5.8 S/m). Moreover, the hydrogel with electrically sensitive perception of external strain (GF = 2.5), can withstand large bending and compression deformations and can be used as a motion sensor to monitor human movements such as arm and finger bending, pressing, and subtle fist clenching. The resulting hydrogel presented excellent antibacterial activity against Escherichia coli and Staphylococcus aureus. As the hydrogel was applied as electrolyte, the developed super-capacitor exhibited a desirable specific capacitance of 404.5 mF.cm-2, with a maximum energy density of 53.93 Wh.kg-1 and capacitance retention of 80.3 % after 2000 consecutive charge-discharge cycles. The ZCNF/ PSAA hydrogel has great potential for applications in flexible strain sensors and energy storage devices.

Abstract ：
Adhesive patches are optimum candidates for distinct biomedical applications, including tissue adhesion and leakage sealing in outpatient or surgical procedures. Unfortunately, most adhesive patches are significantly less effective at providing strong adhesion to the surface of wet tissue, which increases the risk and reduces the fault tolerance in surgery. Meanwhile, customization is difficult to achieve in terms of mechanical adaptability. To tackle this problem, we developed a chitosan-containing bioadhesive patch (ANC) comprising dual-crosslinked carboxymethyl chitosan methacrylate (CMCS-MA), acrylic acid, and acrylic acid N-hydroxysuccinimide ester. This ingenious and convenient design strategy facilitates the integrated polymerization of the patch, while circumventing the necessity for additional crosslinkers. ANC patches in dry state and the rich carboxyl groups contained therein enable rapid removal of moisture from tissue surfaces. Subsequently, robust adhesion based on hydrogen bonding and N-hydroxysuccinimide (NHS)-amine interaction is formed. The dual-crosslinked ANC patch achieves good adjustable mechanical performance and swelling behavior by controlling the addition of CMCS-MA. Furthermore, compared with commercially available fibrin glue, ANC patches own robust adhesion and superior sealing performance for stomach fluid leakage. This intricately designed ANC patch sheds new light on biomedical patch design and broadens the scope of chitosan-containing materials in tissue adhesive and sealant applications.

Abstract ：
The demand for biomaterials with bi-or multi-layered structures, such as cartilage scaffolds, bionic skin, and asymmetrical Janus repair patches, is rapidly increasing. However, existing manufacturing methods face challenges in simultaneously fabricating bilayer structures and ensuring strong interfacial bonding. Here, we present a synergistic strategy, "Freezing-While-Lifting" (FWL), for fabricating bi-layered materials without the need for external adhesives. Inspired by natural non-equilibrium liquid-liquid phase separation (LLPS) observed in river-sea junctions, FWL is synchronously accomplished by using a baffle to regulate the coupling process between non-equilibrium LLPS and freeze casting. Using collagen as a model material, we demonstrate the versatility and stability of FWL in producing bi-layered scaffolds. This approach is also applicable to common water-soluble polymers (such as PVA, PEG, and CMCS) and even oil-in-water collagen Pickering emulsions. Our results highlight that FWL provides a controllable platform for advanced bilayer material design, overcoming challenges in layer integration and offering new insights for the development of functional biomaterials.
