Precise monitoring is of great significance for diabetes management. In contrast to enzyme-based glucose sensors, nonenzymatic ones offer advantages such as improved stability, higher sensitivity, and reduced manufacturing expenses. In the present research, nitrogen-doped carbon nanotube-encapsulated cobalt particles (Co@NCTs-800) were synthesized via a high-temperature pyrolysis and applied to high-efficiency glucose detection. This material benefits from a large number of Co 4+ active sites formed by electrooxidation, along with the high surface area and conductivity of the N-doped carbon nanotube matrix. As a result, Co@NCTs-800 showed outstanding electrocatalytic properties, achieving remarkable sensitivity reaching up to 141.3 μA mM −1 cm −2 , a rapid response duration of merely 1.9 s, along with a minuscule detection threshold of 2.3 μM. The sensor also demonstrated strong resistance to various interfering substances, good stability and reproducibility (RSD = 3.24%). Furthermore, reliable glucose detection in real beverage samples confirmed the practical applicability of the proposed sensor. The successful fabrication of cobalt particles encapsulated in nitrogen-doped carbon nanotubes offered in-depth understanding regarding the advancement of highly efficient non-enzymatic electrochemical glucose sensing.

Photocatalytic hydrogen evolution represents a promising strategy for sustainable energy conversion, yet its efficiency is often limited by the rapid recombination of photogenerated carriers and insufficient redox capabilities. In this work, an S-scheme ZnMn 2 O 4 /CdO (ZMO/CdO) heterojunction was successfully fabricated via a simple solvothermal method to address these challenges. Based on band structure analysis, the composite satisfies the thermodynamic prerequisites for photocatalytic hydrogen evolution. The establishment of an S-scheme charge transfer pathway, driven by the combined effect of an internal electric field (IEF) and band bending, enables photogenerated electrons (e − ) to accumulate in the conduction band (CB) of ZnMn 2 O 4 (ZMO), while holes (h + ) are retained in the valence band (VB) of CdO. This mechanism not only promotes the spatial separation of photogenerated electron–hole pairs (PEHP) but also preserves the strongest redox ability of the system. Under optimized conditions (pH = 8 with triethanolamine (TEOA)), the ZMO/CdO composite achieves an outstanding hydrogen evolution rate of 2237 μmol∙g −1 ∙h −1 , which is approximately 4.38 and 2.84 times higher than that of pure CdO and ZMO, respectively. Moreover, the photocatalyst maintains high hydrogen production activity and structural stability in diverse real water samples, including municipal water, natural surface water, and even wastewater, highlighting its strong potential for practical solar-driven hydrogen production in complex environments.

Polysaccharides from Lentinula edodes ( L. edodes ) exhibit antioxidant and immunomodulatory activities, but conventional extraction is limited by low efficiency and potential loss of bioactivity. This study evaluated the effects of intense pulsed light (IPL)-assisted extraction on the physicochemical, structural, rheological, and antioxidant properties of L. edodes polysaccharides (LNTs). The ternary IUEH method increased polysaccharide yield (92.7%) and uronic acid content (25.96%) compared with hot water extraction, while improving protein removal and preserving acidic fractions. IPL induced partial depolymerization without altering the β-(1 → 3)-glucan backbones, leading to macromolecular reorganization and improved thermal stability. IPL-treated LNTs exhibited increased pseudoplasticity and elasticity. In simulated digestion, IUEH-derived LNTs showed higher reducing sugar release and DPPH radical scavenging activity (70.55%). These findings demonstrate that IPL-assisted extraction efficiently produces structurally optimized LNTs with improved functional properties, supporting their potential application as functional food ingredients.

The demand for bio-inspired neuromorphic systems drives research on artificial neuronal devices with dual excitatory/inhibitory capabilities. Although perovskite memristors show promise, interfacial barriers and rapid ion migration hinder modulation. This study addresses these challenges through atomic-scale cathode engineering, developing perovskite-based memristor (Au/Ni 1 -rGO/MAPbI 3 /ITO) with nickel single-atom modified reduced graphene oxide (Ni 1 -rGO) cathode. The Ni–O configuration of Ni 1 -rGO with a single Ni atom anchored on rGO, modulates the electronic properties of rGO, reducing Schottky barrier via energy band alignment for bipolar current symmetry and spatially confining iodide ion migration through a high diffusion energy barrier (2.912 eV), conferring 780 ms relaxation. The device achieves 1,000 distinct conductance states and emulates interlayer connections and bidirectional signal transmission in feedback neuronal networks. We demonstrate neuromorphic functionalities: unsupervised competitive learning exceeds 50% clustering accuracy, while cooperative learning solves NP-hard problem 6× faster than simulated annealing, establishing an atomic-engineered approach for high-efficiency neuromorphic hardware.

With the self-powered capability, triboelectric sensors have shown great potential for continuous health monitoring and chronic disease prevention. Porous elastomers provide an efficient strategy to improve the flexibility and output performance of triboelectric sensors. However, increasing the flexibility usually makes a compromise in the response range. Herein, a triboelectric sensor based on gradient-pore conductive silicone rubber (G-CS) nanocomposite is fabricated, which provides high sensitivity and a wide detection range. Based on three layers of hierarchical pores, G-CS triboelectric sensor exhibits excellent flexibility (a compressive strain of 70 % per layer), a wide detection range (1.06 kPa ∼ 83.88 kPa), and high sensitivity (0.149 kPa⁻¹). Additionally, the self-foaming strategy combined with layer-by-layer casting and curing simplifies the fabrication process. The carbon nanotubes are introduced in the matrix, which provides conductivity while preserving the inherent flexibility. The gradient structure enables G-CS triboelectric sensor to detect both subtle and substantial pressure of human movement. The single G-CS sensor can be utilized to monitor sports, including foot movement and joint flexion. Moreover, G-CS sensors can be integrated into array-based smart cushions to detect the sitting state. The research shows the great potential to prevent sports injuries and improper posture, paving the way for self-powered smart healthcare.

To address consumer concerns regarding exudate from fresh chicken, this study aims to develop an active food packaging material with excellent antibacterial properties, mechanical strength, and moisture management capabilities by preparing oxidized corn starch/polyvinyl alcohol/agarose (OST/PVA/AG) composite pads using oxidized corn starch (OST) as a functional enhancer. Fourier transform infrared spectroscopy and X-ray diffraction analyses confirmed that OST was successfully incorporated into the PVA/AG matrix through intermolecular hydrogen bonding and esterification cross-linking reactions. These interactions enhanced intermolecular forces and reduced the material's crystallinity. Microscopic morphology revealed that the composite pads exhibited a homogeneous porous structure, with thickness and color varying with increasing OST content. Performance tests indicated that the antibacterial efficacy against E. coli and S. aureus improved significantly in a dose-dependent manner as the OST content increased. Considering the overall performance, the composite pad containing 1% OST demonstrated optimal antibacterial effects (inhibition rate exceeding 99%), mechanical properties (tensile strength of 0.54 MPa, elongation at break of 72%), and water absorption capacity (4.5 g/g), with a cell viability of 85%, indicating good biocompatibility. Chicken preservation experiments further confirmed that the OST/PVA/AG-IV pad effectively absorbed exudate and inhibited microbial growth. After 6 days of storage, the total volatile basic nitrogen (TVB-N) value of the chicken was maintained at 14.81 mg/100 g, and the total viable count remained below the spoilage threshold, significantly extending the shelf life by approximately 1 day compared to the control group. These results confirm the promising application potential of OST/PVA/AG composite pads in the field of meat preservation.

The competition between the intramolecular hydrogen bonds (intra-HBs) in astaxanthin (AST) and the intermolecular hydrogen bonds (inter-HBs) between AST and ethanol (EtOH) controls the structural stability of AST in the solution during the cooling process. This study employs an integrated approach combining Moving window Two-Dimensional (MW2D) correlation Raman spectroscopy and density functional theory (DFT) simulations to investigate the interaction between ethanol (EtOH) and astaxanthin (AST) across a temperature range of 303 K–83 K. The MW2D analysis indicates that, below 253 K, EtOH reorganizes into cooperative multimers prior to any conformational change in AST. DFT simulations demonstrate that EtOH multimers weaken the intramolecular hydrogen bonds (intra-HBs) in AST through O H⋯O C interactions. These findings clarify the apparent contradiction between the extended conjugation length of AST and weakened inter-HBs.

The photothermal catalytic reduction of CO 2 to synthesize high-value hydrocarbon fuels has attracted significant attention. However, current conversion efficiency remains constrained by the dual limitations of insufficient photogenerated carrier concentration and the difficulty in effectively adsorbing and activating CO 2 . This work first successfully synthesized g-C 3 N 4 nanohollow spheres using a hard template method and ultrathin Bi 2 MoO 6 nanosheets via a solvothermal method, and then fabricated an S-scheme heterojunction by electrostatic assembly. Crucially, during the photothermal catalytic reaction, the dynamic formation of photogenerated oxygen vacancies and their induced dipole-limited domain field (DLDF) structure were identified as the key mechanism driving the exceptionally high activity in CO 2 photoreduction. In situ electron paramagnetic resonance spectroscopy directly demonstrated the dynamic cycling of the photogenerated oxygen vacancies during the catalytic reaction. Density functional theory calculations and carrier dynamics characterization analysis confirmed the synergistic effect of the DLDF in optimizing carrier kinetics and enhancing CO 2 adsorption. Ultimately, a high CO production rate of 48.69 μmol·g −1 ·h −1 was achieved. This work integrates heterojunction construction and morphology control strategies to achieve synergistic enhancement of photothermal catalytic performance and elucidates the intrinsic mechanism for the activity improvement. It provides an effective way for developing efficient heterojunctions for photothermal catalytic CO 2 reduction.

The development of semiconductor-based surface-enhanced Raman scattering (SERS) substrates is often hindered by their limited sensitivity. Crystal facet engineering has been recognized as an effective strategy to improve the SERS performance of semiconductors. However, the underlying mechanism by which different exposed facets influence SERS activity in bimetallic oxide systems remains unexplored. In this study, we successfully synthesized NiCo 2 O 4 and ZnCo 2 O 4 bimetallic oxides with distinct exposed facets by regulating the alkali source. When evaluated using 4-Nitrothiophenol (4-NBT) as a probe molecule, the {110} facet demonstrated the highest SERS activity in both oxide systems. The enhancement factors (EF) reached 5.56 × 10 4 for NiCo 2 O 4 and 7.41 × 10 4 for ZnCo 2 O 4 . The limit of detection (LOD) was as low as 10 −7 M and 10 −8 M, respectively, as well as the excellent repeatability and stability. Energy level structure reveals that the superior SERS properties on the {110} facet can attributed to their higher VB maxima, which enhances the thermodynamic driving force and kinetic efficiency of the interfacial charge transfer (CT) process. Moreover, first-principles calculations further illustrate that the CT efficiency on the {110} facet can be effectively improved. This work provides a clear new direction for designing high-performance semiconductor SERS substrates through precise facet control.

Marine corrosion poses a critical threat to the safety of offshore oil and gas facilities. To address the intrinsic drawbacks of pristine TiO2, ZnS/CdS/Ti3+-TiO2 nanotube composites were rationally fabricated via a synergistic strategy combining electrochemical anodization and successive ionic layer adsorption and reaction (SILAR) techniques. Structural and optical characterization confirmed that the as-synthesized composites feature a well-constructed cascade band alignment, which efficiently mitigates the recombination of photogenerated electron–hole pairs. Accordingly, the optimized photoanode delivered a high photocurrent density of 279 µA cm−2. When coupled with 316 stainless steel (316 SS), the composite exhibited a pronounced photo-induced potential of −0.89 V (vs. SCE), achieving a remarkable performance enhancement over pristine TiO2. This enhanced photocathodic protection originates from the synergistic interplay between Ti3+ self-doping and the ZnS/CdS heterojunction: Ti3+ self-doping introduces abundant electron donors to enhance the electrical conductivity of the composite, whereas the ZnS/CdS heterojunction broadens the visible-light absorption range and accelerates the separation and directional migration of photogenerated charge carriers.

The electrochemical oxidation of 5-hydroxymethylfurfural (HMFOR) offers a promising route for biomass upgrading. However, its kinetics are severely hindered by the competitive adsorption between key reactive species on catalyst surfaces. Herein, we report a CoO/Ni 3 N-2:3 heterojunction catalyst that enables efficient and selective conversion of HMF to 2,5-furandicarboxylic acid (FDCA). A “bipolar synergistic adsorption effect” is identified at the CoO/Ni 3 N-2:3 interface. This effect is driven by a built-in electric field (BIEF) generated through interface polarization and the work function difference (ΔΦ) between Ni 3 N and CoO. In situ spectroscopic studies and theoretical calculations reveal that the BIEF acts as an electron sorter, directing OH − and HMF to respectively adsorb at oppositely charged regions while strengthening their adsorption. This spatially oriented adsorption effectively lowers the reaction energy barrier and suppresses competitive adsorption of key reactive species, thereby enhancing both activity and selectivity. As a result, the CoO/Ni 3 N-2:3 catalyst initiates HMFOR at a low potential of 1.18 V RHE and achieves complete HMF conversion at 1.408 V RHE with 99.2% FDCA yield and 97.2% Faradaic efficiency. This work provides an innovative strategy for designing high-performance electrocatalysts for biomass valorization.

This work aimed to prepare organo-montmorillonite (PB-MMT and PD-MMT, namely O-MMT) adsorbent with hydrophobic properties and hydrogen bond acceptor capacity via modification with Gemini surfactants (PB and PD), and to investigate the key role of long alkyl chains and amide bonds in the adsorption behaviors of 4-nitrophenol (4-NP) and 4-chlorophenol (4-CP) in aqueous solutions. The microstructure, morphology and surface propertie of O-MMT were explored by different techniques, including XRD, BET, SEM, FT-IR, TGA and Zeta potential. The results show that the saturated adding amount of PB and PD is 1.0 CEC, and PD with flexible alkyl spacer shows markedly higher loading amount (38.22 wt%) on Na-MTT than PB with rigid spacer (36.35 wt%). The batch experiment results of O-MMT to 4-NP and 4-CP demonstrate that the two are ranked by adsorption capacity as follow: PD-MMT > PB-MMT. Kinetic studies are found pseudo-second-order (R 2 > 0.99) and equilibrium data are fitted well by Freundlich isotherm model (R 2 > 0.99) which indicate the adsorption process is primarily multilayer adsorption. The calculated thermodynamic parameters exhibit that the adsorption processes of 4-NP and 4-CP on O-MMT are physical adsorption and exothermic. Adsorption mechanisms highlighted the synergistic effects of hydrophobic interactions and O-H···N hydrogen bonding as important design criteria for efficient removal of 4-NP and 4-CP from aqueous solutions.
