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%.

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.

Magnesium potassium phosphate cement (MKPC) coatings exhibit excellent bonding properties and environmental friendliness. However, as an inorganic coating, MKPC coatings exhibit poor impermeability. This study utilized hexadecyltrimethoxysilane (HDTMS), CaCl₂ and NaHCO₃ to achieve hydrophobic treatment of the MKPC coating surface. Effects of hydrophobic treatment on the properties of the coating and substrate were characterized by various tests, and mechanisms of corrosion resistance were explored. The results indicate that reducing the surface energy of the coating by HDTMS can improve hydrophobicity of the coating, and increasing the surface roughness by generating CaCO₃ can further enhance the hydrophobicity. Surface treatment enables the coating to maintain prolonged hydrophobicity in a 3.5% NaCl solution. Meanwhile, hydrophobic treatment inhibits the formation of hazenite, enhances the permeability resistance of MKPC, and can provide a long-term improvement in the corrosion resistance for low carbon steel, the best sample exhibited a corrosion current density that was one-third that of the untreated sample after 28 d of immersion.

Eutectic inorganic hydrated salts are promising for passive building thermal management but are hindered by severe supercooling, phase separation, and leakage. To overcome these challenges, this study developed a novel composite eutectic phase change material (CEPCM) based on a dual-network aerogel with compound nucleation. Sodium acetate trihydrate (SAT) and sodium thiosulfate pentahydrate (STP) were selected as the eutectic PCM, while borax and nano-TiO₂ served as compound nucleating agents to synergistically suppress supercooling and prevent phase separation. A polyvinyl alcohol/starch/expanded graphite (PVA/starch/EG) dual-network aerogel was synthesized as a porous, shape-stable supporting matrix to encapsulate the PCM and prevent leakage. The resulting CEPCM exhibits a high phase change enthalpy of 181.4 J/g, an extremely low supercooling degree of 1.1 °C, and excellent shape stability with no leakage. It also demonstrates good flame retardancy (LOI > 95%), high compressive strength (62.437Mpa), and stable performance over 150 thermal cycles. When integrated into a roof module in a scaled building model, the CEPCM significantly reduced indoor temperature fluctuations and delayed heat penetration, confirming its strong potential for energy-efficient building thermal management.

Nanozymes hold significant promise for periodontitis treatment, owing to their high catalytic efficiency, multi-enzyme activity, robust stability, and low cost. However, the need for repeated administration and the complex oral environment present challenges in balancing biosafety and efficiency. Herein, we develop a ligand-modulated manganese ferrite nanozyme hydrogel (MFZ@PG) with balanced antioxidant activity and biocompatibility for periodontitis treatment through ZBP1/β-catenin signaling. MFZ@PG is synthesized by encapsulating zwitterionic dopamine sulfonate-modified manganese ferrite nanoparticles within a gel matrix composed of polyvinyl alcohol, gelatin, and borax. The resulting hydrogel demonstrates potent antioxidant capacity, attributed to the innate nanozyme activity of manganese ferrite and the introduced catechol groups, as well as robust adhesiveness due to multiple chemical interactions between borax and polyvinyl alcohol. In vitro experiments demonstrate that MFZ@PG effectively protects MC3T3-E1 cells from H 2 O 2 -induced impairment of proliferation, migration, and osteogenic differentiation. In vivo experiments demonstrate that MFZ@PG significantly promotes alveolar bone regeneration and suppresses bone resorption. Furthermore, transcriptomic analysis indicates that the therapeutic mechanism of MFZ@PG is achieved through the activation of the ZBP1/β-catenin positive feedback loop. Histopathological and blood biochemical analyses demonstrate the good biocompatibility of MFZ@PG. This study presents a safe and efficient therapeutic strategy for periodontitis with high translational potential.

The synthesis of amino acids from CO2 as the sole carbon source is a critical goal for sustainable biomanufacturing, offering a green alternative to conventional production methods plagued by greenhouse gas emissions and resource competition. Here, we construct a highly efficient cell-free enzymatic platform for the direct biosynthesis of aspartate from CO2. Our integrated platform couples a carbon-fixing module using the modified reductive glycine pathway (rGlyP) with a custom-designed synthesis cascade that condenses two glycine molecules into aspartate, driven by glycine oxidase and a redesigned b-hydroxyaspartate cycle (BHAC). A key challenge in this multienzyme system is achieving pathway synergy. To address this, we employed an enzyme-constrained static model to rationally design the optimal stoichiometry of the five-enzyme cascade. This computational approach not only boosted the final aspartate yield by over 25% but was also essential in identifying glycine oxidase (Bs-ThiO) as the primary rate-limiting bottleneck. Through systematic optimization of enzymes, reaction conditions, and feeding strategies, the system finally achieved accumulation of 17.3 mM aspartate (2.3 g/L) within 2 h, reaching an exceptional 92% of the model-predicted theoretical yield. This study establishes a powerful and sustainable platform for green amino acid production and showcases the significant potential of combining computational design with cell-free engineering to advance the frontier of CO2-based biomanufacturing.

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.

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.
