To address the limitations of traditional barrier membranes in alveolar bone regeneration, this study aimed to design and fabricate 3D architected degradable scaffolds with an integrated barrier functional shell and explore their osteogenic efficacy, particularly the effect of shell microstructure on osteogenesis. Four types of scaffolds were fabricated using degradable 45S5 bioactive glass as the raw material through digital light processing technology. Specifically, the control group consisted of scaffold with barrier functional shell that featured through-holes, and the three experimental groups comprised scaffolds with barrier functional shells featured non-through-holes, each with micro-pits of varying depths (0 μm, 60 μm, and 120 μm). The integrated scaffold exhibits excellent biological activity, appropriate degradability of 29.87 ± 6.89% at 12 weeks, and matched mechanical properties with compressive strength of 9.12 ± 1.82 MPa and elastic modulus of 0.98 ± 0.23 GPa. Experimental results indicated that the non-through-holes shell groups achieved a significantly greater osteogenic height of 4.53 ± 0.11 mm compared to the through-holes group of 3.25 ± 0.14 mm. Notably, the deepest micro-pits at 120 μm group showed the most remarkable osteogenic efficiency with a bone volume fraction of 30.72 ± 5.52% and a bone area fraction of 28.29 ± 3.67%. In conclusion, this study confirms that the scaffold with an integrated barrier functional shell possesses excellent barrier and osteogenic properties. By adjusting the design of the microstructure on the shell, its barrier function can be effectively regulated, thereby providing a practical and effective solution for alveolar bone regeneration.

The incorporation of microstructural designs into flexible sensors has emerged as a potent strategy to enhance the capability of capturing fine information. Herein, an ionic liquid microemulsion-template strategy is presented to fabricate conductive heterogels with a bicontinuous structure of interpenetrating hydrophilic and hydrophobic phases, in which the hydrophilic ionic liquid domain functions as ion-rich channels and provides conductivity. The hydrophobic polymer domain serves as a supporting skeleton. Amphiphilic zwitterions anchored at the phase interface serve as effective ion transport sites to improve ion conduction. The bicontinuous structure enhances the mechanical performance, anti-swelling, thermal stability and ion conductivity of the heterogels. The assembled flexible sensor exhibits the sensitive detection of subtle muscle movements and specific recognition of speech, weight and temperature. This study is expected to provide innovative insights into the design and regulation of ion channels in flexible sensing devices.

Long pepper (LP), a traditional spice, has dried fruits rich in bioactive phytochemicals with nutritional and health benefits. However, the geographic heterogeneity and spatial distribution of key bioactive compounds remain poorly understood, limiting quality standardization and practical applications. This study integrated multidimensional identification, metabolomics, antioxidant evaluation, and spatial metabolomics to systematically examine the geographical variations and distribution patterns of potential quality markers. Initially, 177 compounds were tentatively identified by conventional GC–MS library matching, which was further refined using a multidimensional strategy, leading to the accurate characterization of 113 volatile constituents, with 53 newly reported compounds in LP fruits. Chemometric and correlation analyses revealed 12 significantly differentiated metabolites associated with environmental factors. Six alkaloids were screened as potential quality markers using antioxidant assays and molecular docking. Spatial metabolomics further illustrated their macro- and micro-distributions. This study provides a scientific basis for the quality evaluation and functional food development of LP fruits.

To improve the thermal safety, hydrophilicity and ion transport performance of polypropylene (PP) separators in lithium-ion batteries, a composite coating was developed using amino-modified zeolitic imidazolate framework material (ZIF-67-NH 2 ) and aramid nanofiber (ANF). The coating was applied to the PP separator via a two-step sequential method: (1) ANF dispersion was coated onto the PP substrate to form a support network layer with high mechanical strength and excellent thermal stability; (2) ZIF-67-NH 2 dispersion was uniformly loaded on the ANF layer to construct a functional layer with high specific surface area, regular pore structure and rich active sites. Amino modification of ZIF-67 significantly improved its electrolyte affinity and lithium-ion transport activity. Compared to the pristine PP separator, the modified separator exhibited a thermal shrinkage rate of only 31% at 170°C, indicating superior thermal stability. The water contact angle reached 20°, indicating significantly enhanced wettability. The impedance decreased from 105.6 to 71.2 Ω, and the apparent ionic conductivity increased from 0.0118 to 0.0877 mS/cm. In the cycling test, the battery using the modified separator exhibited an initial discharge capacity of 80 mAh/g, which is approximately 8% higher than that of the battery using the pristine PP separator (73.9 mAh/g), also demonstrating improved capacity retention and stability.

Flexible metal–organic frameworks (MOFs) with dynamic adaptability offered exciting opportunities for advanced separation, yet their tendency to undergo void collapse severely limited their application as gas chromatography (GC) stationary phases. Here, we overcame this challenge by stabilizing the scu -topology Zr-MOF NU-903 through a linker installation strategy. By incorporating biphenyl-4,4′-dicarboxylic acid (BPDC) into the vacant coordination pockets along the c-axis, the resulting material, NU-903-BPDC, exhibited markedly enhanced stability and structural rigidity, retaining its porosity even at 250 °C. Comprehensive characterization confirmed that the original structure was preserved, while framework flexibility was effectively suppressed. Fluorescence spectroscopy further revealed restricted ligand dynamics, corroborating the rigidified framework environment. When employed as a GC stationary phase, NU-903-BPDC delivered significantly improved resolution for C 7 hydrocarbons and dichlorobenzene isomers, benefitting from stronger thermodynamic interactions and reduced band broadening. Crucially, NU-903-BPDC maintained stable separation performance after thermal treatment, in sharp contrast to the pronounced degradation observed for pristine NU-903. This work demonstrated linker installation as an effective strategy to modulate framework flexibility, opening a general pathway toward robust, high-performance MOF-based stationary phases for chromatographic separations.

Continuous in vivo monitoring of diverse chemicals, including ions, glucose, and neurotransmitters, is pivotal for elucidating complex physiological processes and identifying various diseases. Existing approaches predominantly rely on transdermal wires to transmit signals from implanted sensors to external devices, which substantially heightens the risk of infection, particularly in immunocompromised patients. To address this problem, we developed an interface-free implants-to-textile wireless system for multiplexed in vivo chemical monitoring. This system integrates fully implanted miniature wireless sensors, roughly the size of a grain of rice, with a conformal textile-based network of intermediate relay coils. These implanted sensors convert chemical signals into distinct resonance frequencies and wirelessly relay them through the textile–coil network to a readout coil. By obviating the need for transdermal wires, our system mitigates infection risk and achieves real-time and simultaneous monitoring of glucose, potassium and calcium ions in vivo. This minimally invasive platform offers safe, real-time, multiplexed chemical analysis, thereby contributing to advancing both disease diagnosis and understanding of intricate physiological dynamics.

Constructing specific noble metal/metal—organic framework (MOF) nanoheterostructures is an effective strategy for promoting water electrolysis, yet remains highly challenging due to complex synthesis methods, difficulties in structural characterization, and the demanding nature of performance optimization. In this work, a heterojunction electrocatalyst was developed through growing Ru nanoparticles on NiFe-MOF nanosheets (NSs) supported by nickel foam (NF) using an easily accessible solvothermal method followed by an annealing strategy. Owing to the electronic interaction between Ru nanoparticles and NiFe-MOF NSs, the optimized Ru@NiFe-MOF/NF catalyst exhibits excellent bifunctional performance for the hydrogen evolution reaction (with an overpotential of 84 mV at 10 mA·cm −2 ) and the oxygen evolution reaction (with an overpotential of 240 mV at 10 mA·cm −2 ) in a 1.0 mol·L −1 KOH solution, which is superior to that of commercial catalysts. This study highlights a promising strategy for designing and developing efficient electrocatalysts for overall water electrolysis.

The aim of this study was to synthesize magnetic chitosan microspheres (MCM) for the deproteinization of crude polysaccharides from Ostrea rivularis Gould (ORP), and evaluate their adsorption properties. Firstly, MCM were synthesized by microemulsion process. Then they were characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD) and vibrating-sample magnetometer (VSM). At last, MCM was applied as a magnetic separable adsorbent for deproteinization of ORP. The results showed that MCM had smooth surface with particle diameter of 2–6 μm. The adsorption kinetics and adsorption isotherms were well fitted by the pseudo-second order equation and the Freundlich equation, respectively. Comparing with the Sevag method, MCM exhibited higher deproteinization ratio, higher polysaccharides recovery, and miner pollution. In addition, the deprotenaization capacity can be regenerated. Therefore, MCM would be used as promising adsorbents for the deproteinization of polysaccharides.

The rate constant of low-energy electron attachment to CH 2 ClBr was determined using atmospheric pressure nitrogen corona discharge electron attachment ion mobility spectrometry at ambient pressure and room temperature in the mean electron range between 0.35 and 0.69 eV. The rate constants are in the order of magnitude of ∼10 −9 cm 3 molecule −1 s −1 and agree well with the reported value. Only one peak was observed in the production of low-energy electron attachment to CH 2 ClBr and it might be the overlap of hydrated anions Cl − (H 2 O) n and Br − (H 2 O) m . In order to clarify the contribution of Cl and Br anions, acetic acid was utilized to react with the hydrated Cl/Br anions. The H 2 O molecules in the hydrated Cl/Br anions were substituted by CH 3 COOH molecules, and formed Cl − (CH 3 COOH) p and Br − (CH 3 COOH) q , respectively. The contribution of hydrated Cl anions of low-energy electron attachment to CH 2 ClBr was found to be negligible, whereas the hydrated Br anions were the main product ions.

Selenium (Se)-based materials present an interesting opportunity for rechargeable battery systems. Effective physical and chemical immobilization of Se can inhibit the dissolution of polyselenides and the side reaction between Se anions and carbonate-based electrolytes to improve the electrochemical properties. Here, a sulfur and oxygen co-doped hierarchical porous carbon (SO-HPC) is proposed as an effective reservoir to confine Se. The resulting Se/SO-HPC cathode exhibits significantly high rate capability and excellent cycling stability in carbonate electrolyte for Li/Na/K–Se batteries. Moreover, the performance in a wide temperature range and the self-discharge characteristics are appealing for extended practical application. As a result, the Li–Se cell exhibits outstanding capacities of 394 and 264 mA h g−1 at 0.5C after 400 cycles at temperatures of 50 °C and 0 °C. And the capacities of the electrode material show no decay after a rest period of 150 h under the same temperature conditions.

Near-infrared phosphor-converted light-emitting diode (NIR pc-LED) is becoming a smart light source for portable multifunctional devices, utilizing in fields like bio-imaging, night-vision, and food-quality analysis. However, developing broadband, inexpensive, and efficient NIR phosphors are still in great challenges. Herein, we report a phosphate LiAlP 2 O 7 :Cr 3+ phosphor by choosing highly distorted and inexpensive octahedral Al 3+ -containing compound as host. This material generates a broadband NIR emission with peak located at 844 nm and a full width at half maximum (FWHM) of 163 nm under 450 nm excitation. Amazingly, the absorption efficiency (AE) was measured to be as high as 64%, being higher than most of Cr 3+ -activated polycrystalline materials . Unfortunately, the internal quantum efficiency (IQE) was only 26.7%, and the emission intensity at 373 K kept only 56% of that at room temperature . The detailed reasons for these undesired properties are systematically investigated. Moreover, a prototype NIR pc-LED fabricated by using this material combining with 450 nm LED chip demonstrates a NIR output power of 9.7 mW and NIR photoelectronic conversion efficiency of 3.3% under 100 mA driving current, indicating the feasibility of this material to be applied in NIR pc-LEDs.

A nano-carbon composite, consisting of a graphene aerogel-carbon nanotube (CNT) film, is constructed by coating a strong and flexible CNT film onto the surface of a porous graphene aerogel core. The prepared gradient composite, ultralight and strong, can carry objects more than 15,000 times its own weight, exhibiting impressive compression resistance. Compared to the original graphene aerogel , the composite exhibits 8–9-fold increased values in its elastic modulus and compressive strength at a strain of 20% and an approximately 10-fold increase in electrical conductivities in the axial direction . In addition, the elastic recovery ability after compressive deformation and the ability to preserve liquid are also improved.
