Pain, arising from chronic abnormal activation of nerves and tissues, contributes to dysfunction and reduced quality of life. A single mechanism and short duration of action limit the effectiveness of current local analgesics. Chinese Acupuncture (CA) influences the immune-neural circuit by triggering mast cell (MC) degranulation at acupoints but lacks precise control. This study introduced a magnetoelectric hydrogel acupuncture system that responds to external magnetic stimulation. Using screw-threaded needles, a hydrogel containing magnetically responsive piezoelectric nanoparticles was accurately administered to pain-related acupoints, targeting MCs. Under magnetic fields, these nanoparticles produce coupled “mechanical force-electrical” stimulation, promoting MC degranulation and converting physical cues into biochemical mediators acting on nerve endings to achieve analgesia. In vitro, the system enhanced Ca 2 + influx and RBL-2H3 degranulation, leading to the secretion of mediators such as histamine, 5-HT, and ATP. In vivo validation confirmed the system's specific activation of MCs beneath the ST-36 acupoint, specifically triggering MC degranulation and regulating peripheral TRPV1 and dorsal root ganglia A1R expression, thus inhibiting pain transmission. Decreased proinflammatory cytokines, elevated cerebrospinal β-endorphin, and improved pain thresholds indicated integrated immune–neuro–endocrine regulation. In conclusion, this magnetoelectric hydrogel acupuncture enables effective and sustained analgesia via controllable MC-mediated neuroimmune modulation.

The adsorption of charged nanoparticles at water-oil interfaces constitutes a fundamental phenomenon, underlying pivotal technologies spanning from emulsion stabilization to the sophisticated fabrication of foams. However, the diffusional behavior of these nanoparticles remains poorly understood. Here, we use single-molecule tracking experiments to show that the diffusion of like-charged nanoparticles at the water-oil interface not only becomes anomalous but also displays a diffusional aging phenomenon at the interfacial coverage that is not associated with the glassy state. We further develop a theoretical framework that quantitatively reproduces all experimental observations. Molecular dynamics simulations reveal the necessity of the coexistence of attraction and repulsion for the emergence of aging dynamics. The interplay between attraction and repulsion leads to nanoparticle adhesion taking place over observable timescales, which is manifested as aging dynamics. The discovery of diffusional aging demonstrates that interfacial evolution persists beyond adsorption equilibrium, suggesting that this effect must be accounted for in applications involving water-oil interfaces laden with charged nanoparticles.

The performance of surface-enhanced Raman scattering (SERS) hinges on plasmonic hot spots that are both abundant and spatially uniform. Here, we propose a ligand-regulated, interface-confined growth strategy: on a bowl-like mesoporous polydopamine (PDA) scaffold, the ammoniacal silver precursor [Ag(NH 3 ) 2 ] + first forms a surface coordination layer with catechol and amine sites on PDA, lowering the activity of free Ag + and enriching Ag(I) at the interface, thereby shifting nucleation from homogeneous in the bulk to interface-confined. The ensuing constrained growth suppresses coalescence/bridging and excessive coarsening, yielding Ag nanoparticle arrays with controlled size, tunable interparticle gaps, and high spatial uniformity, and producing dense yet discrete coverage across both the inner and outer interfaces of the bowl. The concave curvature and dual-interface connectivity provide continuous coupling pathways and abundant adsorption sites, establishing a three-dimensional continuous hot-spot network. Correlative multi-technique characterization and spectroscopic analyses (SEM, EDS mapping, UV–Vis, XPS) elucidate the structure-optical-performance relationship, revealing a sparse-to-dense optimal regime and a coalescence-induced degradation regime, and identifying a precursor concentration of 50 mM as the optimal window. The resulting substrate exhibits good reproducibility for R6G (RSD ≈ 10.99 %) and affords clear molecular fingerprinting and linear quantification for pesticide analysis, with limits of detection of 55 ng mL −1 for methyl parathion and 0.209 ng mL −1 for thiram. This template-free, mild, and generalizable strategy provides a scalable route to three-dimensional plasmonic SERS substrates, leveraging PDA surface chemistry to prevent Ag aggregation at the source while constructing continuous hot spots networks.

To address the issue of reduced photovoltaic conversion efficiency and heat waste caused by excessive temperatures under sunlight, this study developed a cooling system (CTW-MPCM) that combines paraffin-based phase-change energy storage microcapsules with waste heat recovery for cooling and thermal energy recovery in photovoltaic panels. The results show that by adjusting the irradiance intensity (400 W/m 2 ~ 800 W/m 2 ) with a solar simulator, the PV panels with the CTW-MPCM system demonstrated an average temperature reduction of 14.6 °C ~ 23.3 °C on the front surface and 24.3 °C ~ 30.6 °C on the back, with a photoelectric conversion efficiency increase of 5.07–13.84 %. At 800 W/m 2 , the thermal recovery efficiency was 82.1 %. The system maintained high cooling performance even under real environmental conditions and the heat transfer process of the system was simulated at both macro and micro scales using finite element analysis. This work combines phase-change energy storage microcapsules with a waste heat recovery system, solving the common leakage problem of traditional phase-change materials and providing a more efficient solution for thermal regulation and waste heat recovery in photovoltaic panels.

To address the urgent demand for efficient solar-to-hydrogen conversion, a novel Cu-doped 3D ordered macroporous (3DOM) ZIF-8 photocatalyst was fabricated via polystyrene sphere templating coupled with a dual-solvent method. Systematic characterization confirmed the preservation of the ZIF-8 crystalline structure after ∼2 at% Cu2+ incorporation. The 3DOM framework amplified light absorption via slow-light effects, while Cu2+ doping narrowed the band gap and further intensified the slow-light phenomenon. The optimized Cu-3D-ZIF-325 exhibited a photocatalytic hydrogen evolution rate of 2233.2 µmol g−1 h−1, which is 29 times higher than that of pristine ZIF-8. This performance enhancement originated from synergistic mechanisms: EIS measurements revealed that Cu2+ sites improved charge separation, and the optimized band structure facilitated carrier transport; DFT calculations further verified that Cu2+ optimized the adsorption/dissociation of water and elevated the conduction band potential, strengthening the reductive driving force for H2 production. This work establishes a viable dual-modification strategy for high-efficiency MOF-based photocatalysts.

The development of efficient and robust bifunctional oxygen electrocatalysts is crucial for advancing rechargeable zinc-air batteries. Although bimetallic composites are promising, conventional doping strategies often lack precise structural control. Herein, we report a sustainable synthesis of Co/Fe heterojunction catalysts from biorefinery lignin, incorporating low-cost Zn as a structural regulator. Zn spacers suppress CoFe alloy crystallization and promote Co 5.47 N formation, while Zn volatilization induces in situ carbon nanotube growth to enhance electronic structure and charge transport. The resulting Zn-CoFe@NLC catalyst exhibited favorable bifunctional performance, with a half-wave potential of 0.84 V for the oxygen reduction reactionand a high kinetic current density (17.2 mA cm -2 at 0.8 V). When implemented in zinc-air batteries, it achieved long cycling stability exceeding 1300 h (at 5 mA cm -2 ) and 1550 h (at 10 mA cm -2 ), more than 2.5 times that of noble metal catalyst (600 h at 10 mA cm -2 ). DFT calculations revealed that the CoFe-Co 5.47 N interface acted as an electron redistribution hub, synergistically enhancing the intrinsic activity of Co/Fe sites. This work underscores the promise of lignin as a sustainable precursor and establishes a generalizable route for rational structural engineering of bimetallic electrocatalysts for energy storage.

A “signal-off” surface-enhanced Raman scattering (SERS) strategy is developed for the rapid and ultrasensitive detection of total free arsenic in water and traditional Chinese medicine (TCM) beverages. The method employs methimazole (MMI) as a multifunctional probe that first reduces As(V) to As(III) and subsequently forms a As-MMI complex, leading to concentration-dependent attenuation of the characteristic MMI SERS signal. The assay achieves rapid equilibration within 2 min under optimized conditions and exhibits exceptional selectivity for free arsenic over common interfering ions, attributed to the combined redox and As-S complexation mechanisms under acidic pH. Ultrasensitive detection is achieved with a limit of detection of 0.6 fmol/L, more than eight orders of magnitude below the WHO safety guideline for drinking water. Practical applicability is demonstrated through quantitative recovery (93.8–106%) of spiked arsenic in real water and TCM beverage samples with relative standard deviations below 6.1%. This work provides a rapid, selective, and ultra-sensitive platform for free arsenic monitoring in environmental and pharmaceutical quality control applications.

High-performance catalysts for the methanol oxidation reaction (MOR) are critical for advancing direct methanol fuel cells. Here, we report a three-dimensionally ordered macroporous superstructure of nitrogen-doped hierarchical porous carbon (NHPC) implanted with ultrafine Pd nanoclusters (∼1.8 nm) as a highly efficient electrocatalytic micronano reactor (Pd/NHPC). Constructed via nanocasting of ZIF-8 on polystyrene colloidal crystals, followed by the confined growth of Pd, this architecture features interconnected macropores that maximize mass transport and active-site exposure. In alkaline media (1.0 M KOH + 1.0 M CH3OH), Pd/NHPC achieves a mass activity of 7383 mA mgPd–1─surpassing commercial Pt/C and Pd/C by factors of 4.09 and 3.80, respectively. It exhibits exceptional stability, retaining 95.0% activity after 500 cycles at 200 mV s–1, and delivering 2373 mA mgPd–1 after 7200 s chronoamperometry. Mechanistic studies reveal that the hierarchical porosity accelerates reactant diffusion/intermediate desorption, while optimized nitrogen configurations (pyridinic/pyrrolic/graphitic-N) enhance metal–support interaction, enrich electron density on Pd0 sites, and facilitate a direct (CO-poisoning-free) MOR pathway. This work establishes a paradigm for designing stable, high-activity nanocatalysts through synergistic structural and electronic engineering.

The hydrogenation of aliphatic nitriles is an atom-efficient and environmentally benign approach to the synthesis of primary amines. Here, a Pd/Ni/MgO-Al2O3–B catalyst with maximized Pd utilization was successfully designed and fabricated for the selective hydrogenation of aliphatic nitriles to corresponding primary amines, delivering a full conversion of lauronitrile with 99% laurylamine yield under mild conditions (60 °C, 1.5 MPa H2). The remarkable catalytic performance might be attributed to the PdNi synergy facilitating hydrogen adsorption and activation combined with the moderate-strength surface acidity of the MgO-Al2O3 composite support favoring lauronitrile adsorption and laurylamine desorption. Moreover, this catalytic system exhibits remarkable functional group tolerance, excellent recyclability, and exceptional performance for the in situ hydrogenation of aliphatic nitriles into primary amines in industrial wastewater treatment. This work not only provides an effective and practical protocol for the synthesis of primary amines from nitriles but also contributes to sustainable treatment of nitrile-containing wastewater.

The rational modulation of the electronic state via interaction of components is pivotal for optimizing the performance of solid materials in particular for heterogeneous catalysts. Unlike the electron-withdrawing effect of popular supports, herein, it is discovered that a unique electron modulation effect of SmPO 4 (a rare earth phosphate) on nickel (Ni) nanoparticles (10 wt%) supported on AlPO 4 -SmPO 4 composite carrier, enables efficient hydrogenation of furfural (FAL) to tetrahydrofurfuryl alcohol (THFA) under mild conditions (423 K, 1.0 MPa H 2 ). In comparison to the influence of AlPO 4 , comprehensive characterizations (X-ray photoelectron spectroscopy (XPS), high-resolution transmission electron microscopy (HRTEM), and H 2 temperature-programmed reduction (H 2 -TPR)) confirm that SmPO 4 can act as an efficient electron donor, transferring electron to Ni along the AlPO 4 -SmPO 4 interface and forming electron-enriched Ni active sites. This electron-enriched state, coupled with the interface structure of the composite support, constructs a double-site activation system: electron-enriched Ni sites on AlPO 4 -SmPO 4 interface synergistically activate the conjugated C=O and C=C bonds, facilitating efficient and selective complete hydrogenation of FAL. The Ni/AlPO 4 -SmPO 4 catalyst with the optimized Al:Sm ratio exhibits exceptional catalytic performance with a FAL conversion of 99.2% and a THFA selectivity of 94.0%, outperforming most reported Ni-based catalysts under milder conditions. Additionally, the catalyst demonstrates attractive stability and broad applicability for a scope of cyclic unsaturated substrates like FAL. This work highlights the unique electron modulation function of rare earth phosphates in tailoring metal electronic states, and provides a promising strategy for designing high-performance non-noble metal materials for corresponding technically important chemical engineering processes.

Acoustic cavitation, characterized by the nucleation, growth, and collapse of cavitation bubbles under ultrasound irradiation, is a fundamental mechanism for therapeutic ultrasound, including high intensity focused ultrasound therapy and sonodynamic therapy (SDT). In this study, a hierarchical acoustic signal analysis was carried out to systematically evaluate how engineered silica nanoparticles (SiO 2 NPs) regulate cavitation onset, bubble growth, and oscillation stability. Specifically, cavitation thresholds were determined using the third harmonic signal, and calibrated to acoustic intensity (I SPTA ) to assess clinical safety. Our results demonstrate that nanoparticles facilitate bubble nucleation in a size-dependent manner, with maximal enhancement observed at ∼ 100 nm under 840 kHz ultrasound sonication. Structurally, hollow mesoporous silica nanoparticles (HMSNs) induced the most intense cavitation with the lowest threshold of 0.56 W/cm 2 , significantly below the FDA safety limit (3 W/cm 2 ). Furthermore, we propose a unified concave-convex curvature theory to elucidate these phenomena: hydrophobic modifications and hollow architectures create effective concave interfaces that stabilize gas nuclei, drastically lowering the nucleation barrier compared to convex hydrophilic spheres. These findings provide quantitative mechanistic insights into nanoparticle-mediated cavitation and establish key design principles for ultrasound-responsive nanoplatforms that enable effective therapy within clinically safe energy levels.

Thermally regenerative batteries (TRB) hold significant promise for low-grade waste heat recovery due to their unique advantages, such as high power density and simple structure. To address the issues of limited and unstable reaction interfaces in conventional electrodes, this study proposes a hierarchically porous composite electrode fabricated via dynamic hydrogen bubble template (DHBT) electrodeposition. By adding the crystal modifier Janus Green B (JGB), the copper deposition morphology was tailored to form needle-like nanostructures. SEM results confirm the successful synthesis of the nanostructured electrode. Compared with conventional Cu/Ni electrodes, the TRB equipped with the nanocopper electrode demonstrated significantly enhanced performance, primarily attributable to its markedly increased specific surface area. After constructing a porous nickel framework via the DHBT method, the specific surface area was further enlarged, and copper detachment was effectively mitigated, leading to an additional 44.2% improvement in battery performance. The concentration of JGB considerably influenced the nanostructure and battery performance. As the JGB concentration increased, the TRB performance first improved and then declined, with an optimal concentration identified at 0.25 mg/mL. This trend is attributed to the fact that low JGB concentrations have a limited effect on Cu2+ deposition and provide little improvement in specific surface area, whereas excessive JGB molecules occupy active sites on the nickel skeleton, hindering Cu2+ adsorption and deposition, thereby reducing reactive sites. Furthermore, the nanostructured composite electrode developed in this work maintained a stable operation over more than 16 discharge cycles, demonstrating excellent long-term durability. This study provides valuable guidance for electrode design and performance enhancement in thermally regenerative battery technology.
