Crayfish shell protein is an abundant but underutilized resource for developing peptide-based prebiotics to support gut health. However, systematic evidence linking protease selection to peptide structure and subsequent probiotic responses remains limited. This study evaluated five hydrolysis treatments (papain, trypsin, pepsin, alkaline protease, and neutral protease) to identify structure–function determinants for promoting Bifidobacterium animalis subsp. lactis 3296. Papain and trypsin hydrolysates (CSPe-P and CSPe-T) achieved moderate hydrolysis (16.87–22.24% and 17.14–20.39%), balanced molecular weights (7409–7445 Da), semicrystalline organization (48.12–50.60%), and relatively high β-turn and random-coil proportions. These hydrolysates also contained higher total amino acid contents (610.39–625.34 mg/g) and were enriched in Glu, Asp, Arg, and Lys. Functionally, CSPe-P and CSPe-T increased Bifidobacterium animalis subsp. lactis 3296 with final OD 600 values of approximately 1.8–1.9 and maximum specific growth rates at 12 h of 5.14 h −1 and 4.83 h −1 compared with 4.00 h −1 in control. At 12 h, viable counts in the fructooligosaccharides (FOS), CSPe-P, and CSPe-T reached 59.94–64.19 × 10 8 CFU/mL, whereas the control reached 50.0 × 10 8 CFU/mL. CSPe-P and CSPe-T performed comparably to commercial FOS in this in vitro growth assay. In contrast, alkaline and pepsin hydrolysates presented disordered structures and inferior probiotic promotion. Overall, this study provides preliminary in vitro evidence that structure-guided enzyme selection can identify crayfish shell peptides with probiotic-supporting potential.

The skin serves as the largest protective barrier organ of the human body and is easily impaired by trauma, infection and chronic diseases. Efficient wound dressings are indispensable for repairing infected wounds. Isochlorogenic acid A (IAA), the core active ingredient of Shanyinhua, has superior anti-inflammatory and antibacterial effects. However, low water solubility and weak structural stability restrict its direct application in wound treatment. In this work, IAA@Fe(III) nanoparticles (IAA@Fe(III) NPs) were synthesized through self-assembly and loaded into cross-linked amylopectin (Amy)/carboxymethyl chitosan (CMCS) (AC hydrogel) to construct Amy/CMCS@NPs composite dressings. Characterizations demonstrated that nanoparticles displayed a uniform spherical shape with a size of 114.20 ± 2.29 nm and stable coordination. The hydrogel featured a dense porous structure and outstanding mechanical performance, self-healing ability, adhesion, and swelling properties. In vitro tests proved that 50 mg/mL composite hydrogel exerted nearly 100% bacteriostatic activity against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), with good biocompatibility, and enhanced cell migration capacity. In vivo assays indicated an 86.5% wound healing rate at day 7. This dressing could downregulate Tumor Necrosis Factor-α (TNF-α) and Interleukin-1β (IL-1β), upregulate Cluster of Differentiation 31 (CD31) and Vascular Endothelial Growth Factor (VEGF), and accelerate wound repair. This study provides a theoretical and experimental basis for the exploitation of IAA-based wound dressings and high-value utilization of Shanyinhua resources.

Developing blue-light-excitable narrow-band green-emitting materials is crucial for next-generation backlight displays. Here, we designed and synthesized a novel 0D hybrid bismuth halide, (OfloH 2 ) 2 Bi 2 Cl 10 ·3H 2 O (OBCH), using optically active ofloxacin (OFL) as the organic component. Under blue excitation, it exhibits bright narrow-band green-emission peaks at 515 nm. Although OBCH retains the intrinsic green emission originating from protonated OFL solution, its fluorescence exhibits a narrowed FWHM of 59 nm, attributed to enhanced structural rigidity resulting from the rigid bismuth halide framework and the layered stacking of organic cations. Benefiting from its strong blue light excitation, narrow FWHM, a stable white light-emitting diode device was fabricated by combining the 460 nm blue InGaN LED chip, green-emitting OBCH, and red-emitting KSF: Mn 4+ with a luminous efficiency of 92.34 lm/W and a wide color gamut of 109.2% sRGB standard. This work not only provides a universal strategy for utilizing rigid and stable metal halide lattices as “reactors” to confine and modulate the photophysical behavior of organic luminophor, thereby unlocking superior performance unattainable in their free state, but also offers new insights for designing next-generation high-performance luminescent materials.

Superabsorbent polymers (SAPs) derived from sodium alginate have attracted considerable attention. However, their practical application is limited by poor saline absorption and water retention. In this study, a fully biomass-derived SAP was fabricated from sodium alginate and konjac glucomannan via a two-step crosslinking strategy using CaCl 2 and borax as crosslinkers. The microstructure, chemical structure, thermal stability and composition of the optimized SAP were characterized in detail. The dual-crosslinked network, formed through Ca 2+ -carboxylate coordination and dynamic borate ester bonds, enhanced saline tolerance while maintaining structural integrity. The partial disruption of the Ca 2+ crosslinking network by Na + ions relaxed the polymer network to facilitate saline uptake, whereas reversible borate ester bonds enabled network rearrangement and water retention. The optimized SAP exhibited absorption capacities of 35.87 g/g in 0.9 wt% NaCl solution, 18.43 g/g in artificial urine, outperforming most fully biomass-based SAPs and the commercial acrylate-based SAP. Notably, its saline water retention ratio reached 65.07% after centrifugation. Moreover, the optimized SAP achieved an 85.24% biodegradation within 28 days. In summary, the fully biomass-based dual-crosslinked SAP simultaneously improves saline absorbency, water retention, and biodegradability, highlighting its strong potential for hygiene product applications.

Burn wounds present unique challenges for dressings due to severe vascular damage, irregular wound shapes, and excessive reactive oxygen species (ROS). In this work, we designed a bio-based multifunctional hydrogel dressing possessing antioxidant, antibacterial, and angiogenic properties. The hydrogel matrix was functionalized by embedding black phosphorus nanosheets (BPNS) coated with a tannic acid-copper ion complex (BPNS@TA-Cu), thereby imparting unique pH-dependent dual functions to the resulting composite. Specifically, under acidic microenvironments, it demonstrates a synergistic combination of photothermal therapy (PTT) and peroxidase-like (POD) activity, conferring potent antibacterial efficacy. In contrast, under neutral conditions, the material effectively scavenges reactive oxygen species (ROS) and reactive nitrogen species (RNS), thereby exhibiting outstanding antioxidant properties. The hydrogel's rapid self-healing and shape adaptability arose from a dynamic cross-linked network formed via borate ester bonds among gelatin (Gel), polyvinyl alcohol (PVA), cationic guar gum (CG), BPNS@TA-Cu, and borax. This adaptability allowed the dressing to conform to and fill irregular burn wounds, ensuring close contact. The hydrogel promoted full-thickness burn defect wound healing by facilitating granulation tissue formation, epithelial regeneration, and collagen deposition. Collectively, these findings establish the GPC-BTC hydrogel as a viable and promising multifunctional dressing strategy to accelerate burn wound healing.

Chloride salts are regarded as promising candidates for thermal energy storage in concentrated solar power systems, but their low thermal conductivity and specific heat capacity limit their further development and application. Herein, utilizing sodium tetraborate decahydrate and melamine as precursors, nano hexagonal boron nitride (h-BN) was synthesized in situ within NaCl-KCl through spray drying to obtain modified salts. The results indicated that in-situ synthesized h-BN nanosheets (∼50 nm) were uniformly dispersed without obvious agglomeration and exhibited excellent chemical compatibility. Remarkably, modified salts showed a non-linear specific heat capacity increase, reaching a maximum 40.5% enhancement at 1.5 wt.%. Molecular dynamics simulations attribute this to the formation of cation-enriched interfacial layers surrounding h-BN. Simultaneously, the thermal conductivity of modified salts was enhanced from 0.78 to 1.41 W/(m·K) at the optimal loading. Modified salts maintained good thermal properties after 50 thermal cycles, indicating their promising applications in solar thermal energy storage.

Ruthenium-based catalysts have attracted considerable attention owing to their excellent activity in the selective hydrogenation of benzene to cyclohexene. Their catalytic performance is primarily governed by the electronic structure of metallic active sites and the interfacial interaction between the metal and the support. In this work, three types of TiO2support, including nanosheet flowers (TNSFs), elongated bipyramids (TNEBs), and tetragonal bipyramids (TNQBs), were successfully synthesized via a solvothermal route, which predominantly expose the (001), (010), and (101) crystal facets, respectively. Subsequently, ruthenium nanoparticles were deposited onto the support surfaces by means of chemical reduction, yielding three supported catalysts. The exposed (101) crystal facets of TNQBs induce the strongest electronic metal–support interaction (EMSI). Abundant Ti3+defects and oxygen-containing species on the surface endow the catalyst with superior hydrophilicity, enhancing the contact between the reaction medium and active sites as well as the desorption of cyclohexene. Meanwhile, the supported Ru species exhibit the highest fraction of electron-deficient states, with the proportion of Ruβreaching up to 82.22%. As a result, the catalyst exhibits outstanding catalytic performance, achieving a benzene conversion of 42.8%, a cyclohexene selectivity of 82.27%, and a cyclohexene yield as high as 53.22%.

Light driven soft actuators often struggle to integrate robust mechanical toughness, dynamic spatial tunability, and reliable on demand adhesion within a single material system. Here, we present a near infrared (NIR) light responsive hydrogel featuring dynamic noncovalent networks that enable the rapid and reversible reconfiguration of mechanical properties. The structural network integrates PVA chains to provide initial mechanical resilience and environmental durability, while the thermal responsive boronic ester bonds act as crosslinking junctions to ensure fast transition to a soft elastic state. This integrated architecture achieves a rare balance between high initial stiffness and on demand dynamic actuation, overcoming the long-standing trade off in responsive soft matters. Furthermore, the localized photothermal cleavage of the dynamic bonds exposes functional groups, which significantly enhances the interfacial adhesion to diverse surfaces, reaching approximately 48 kPa on aluminum. The localized photothermal reduction in mechanical stiffness endows the hydrogel with precise spatial control, enabling the design of untethered bionic actuators and interactive sensors. Beyond mechanical actuation, the hydrogel serves as a highly sensitive wearable electronic device, achieving precise human motion detection and Morse code communication. Furthermore, the integration of a 4 × 4 spatial pressure sensor array provides reliable tactile feedback for robotic manipulation tasks. This work highlights a versatile design strategy for programmable hydrogels, paving opportunities for smart interfaces, advanced human machine interaction, and adaptive soft robotic systems.

Water-based flame-retardant coatings have attracted more and more attention as versatile strategies for improving the fire safety of flammable polymeric materials. However, the perfect combination of environmental protection, water resistance, durability, optical transparency, and strong interface adhesion is still extremely challenging. Herein, we report a biobased, transparent, and multifunctional flame-retardant coating (GBPK-LDH) constructed from gum arabic, phytic acid, borax, and KH560, reinforced by layered double hydroxide (LDH) nanosheets. The coating has high optical transparency, excellent water resistance, and various organic solvent resistance. Due to the synergistic effect of abundant hydrogen bonds, dynamic borate interaction, and silane-induced interface coupling, GBPK-LDH coating has strong adhesion to different substrates, with a maximum shear strength of 1.73 MPa, and has a self-healing behavior triggered by humidity and temperature. When coated on flexible polyurethane foam (FPUF), the coated foam shows excellent flame retardancy and achieves a rapid self-extinguishing effect. It is worth noting that compared with the control FPUF, the peaks of heat release rate and total smoke production were reduced by 42.5 and 50.0%, respectively. Moreover, the GBPK-LDH coating also helps to improve the mechanical properties of FPUF, including a significant increase in tensile strength, while maintaining excellent resilience and constant thermal insulation. Furthermore, the coating can also provide effective fire protection for other flammable substrates, such as rigid polyurethane foam and wood, highlighting its wide applicability. This study proposes a sustainable and scalable strategy for the development of high-performance biobased multifunctional water-based coatings.

Halides have emerged as promising solid electrolytes for solid-state batteries, owing to their good oxidative stability and favorable mechanical deformability. Nevertheless, the practical application of sodium chloride-based electrolytes has been severely hindered by sluggish Na+-ion transport and a strong reliance on prolonged mechanochemical processing, which substantially increases manufacturing cost. Here, we report a mixed-anion sodium halide-borate solid electrolyte, Na1+xTa(B4O7)xCl6–x, that effectively addresses these limitations. Partial substitution of Cl– by [B4O7]2– units creates mixed Ta–Cl–O coordination polyhedra that induce significant local structural distortion and promote rapid amorphization. As a result, a room-temperature ionic conductivity as high as 3.1 mS cm–1 is achieved within only 10 min of mechanochemical milling. Ab initio molecular dynamics simulations reveal that the incorporation of borate weakens Na+-ion coordination, activates coupled cation–anion dynamics, and enlarges Na+-ion transport bottleneck, which synergistically flattens the cation migration energy landscape for rapid Na+-ion diffusion. Benefiting from fast Na+-ion transport and favorable compatibility with cathode materials, Na1+xTa(B4O7)xCl6–x enables solid-state sodium batteries employing a NaCu0.12Ni0.22Fe0.33Mn0.33O2 cathode to sustain stable cycling for over 800 cycles with a capacity retention of 81.6%. These results establish Na1+xTa(B4O7)xCl6–x as a new class of halide-based superionic conductors and highlight mixed-anion engineering as an effective strategy for developing high-performance solid electrolytes.

Salt lakes are rich in boron, magnesium, potassium, lithium, and other elements of considerable industrial significance. Boron serves as a crucial tracer for investigating geological processes due to its high incompatibility and solubility. However, boron tends to form complex borates with other elements in salt lakes such as magnesium borates. The excessive accumulation of boron in brine, coupled with the phase transition of magnesium borate that releases boron, complicates the study of the boron cycle and contributes to environmental pollution. Therefore, investigating the phase transitions of borates and identifying stable solid phases at various temperatures are crucial for enhancing our understanding of the boron cycle and mitigating pollution in salt lakes. This paper investigated Mg2B6O11–H2O (308.15, 323.15 K) and Mg2B6O11–MgSO4 (5, 10, 20 and 30%)–H2O (308.15 K) systems via isothermal dissolution equilibrium, thermogravimetry, and X-ray diffraction. At 308.15 K, Mg2B6O11–H2O began converting to pinnoite at 237 h, reaching equilibrium at 1000 h; at 323.15 K, conversion started at 33.5 h and finished within 170 h. In MgSO4 solutions (5–30%), inderite remained stable for 68–94 days without transformation.

Tissue hypoxia and bacterial infections are capable of impeding the wound healing process, imposing a significant burden on patients and healthcare systems. Although significant progress has been gained in wound care, traditional dressings are deficient in therapeutic effects. Furthermore, their inability to fit irregular wound geometries and the absence of self-healing properties can compromise the healing process. Inspired by the environmental adaptability and biological plasticity of amoebas, we developed an adaptive hydrogel (PLC hydrogel) with oxygen-releasing and antibacterial activities by loading Chlorella vulgaris and ampicillin based on a matrix composed of PVA and ι-Carrageenan. The hydrogel integrated moldability, adaptability, self-healing ability, and injectability. By incorporating Chlorella and ampicillin, the PLC hydrogel can continuously generate oxygen and inhibit bacterial infections. The hydrogel possessed excellent electrical and sensing output properties, which also exhibited hemostatic capacity and good biocompatibility. Notably, results from in vivo wound healing evaluations indicated that the PLC hydrogel exerted a positive effect on accelerating wound healing. These results highlight the potential of the multifunctional hydrogel in the therapeutic health management of wounds at active sites, as well as in personalized and precise therapeutic diagnosis, thereby providing new insights for the research and development of novel wound dressings.
