Flexible piezoelectric sensors offer excellent wearability and easy integration, making them attractive for smart devices and health monitoring. However, their low piezoelectric coefficient (d33) limits widespread use. In this study, surface-coated barium titanate nanoparticles (mBT) with a core–shell structure were synthesized and incorporated into P(VDF-TrFE) to form composite films. The film containing 10 wt % mBT showed a dielectric constant of 20 at 103 Hz, a 31% increase in residual polarization (7.82 μC·cm–2), a 30% reduction in coercive field (40 MV/m), and a 58% enhancement in quasi-static d33 (41 pC/N) compared with the pure polymer. These improvements arise from enhanced interfacial interactions and phase compatibility due to the mBT core–shell design, which promotes β-phase formation in the polymer matrix. A flexible sensor fabricated from the optimized composite displayed superior pressure sensitivity and linearity (R2 > 0.999). Its dynamic d33 and voltage coefficient (g33) reached 42 pC/N and 244 mV·m/N, improving by 66% and 35%, respectively. The sensor accurately detected low-frequency vibrations (0.5–50 Hz), highlighting the potential of core–shell nanoparticle modification for developing high-sensitivity, low-frequency flexible piezoelectric sensors.

The electrocatalytic CO 2 reduction reaction (ECR) represents a promising strategy for converting CO 2 into value-added chemicals while mitigating greenhouse gas emissions. However, developing efficient and stable electrocatalysts remains challenging. In this study, we synthesized a Ni-based single-atom catalyst (Ni/NSP-C) via pyrolysis of a PZS/Ni-ZIF-8 precursor derived from ZIF-8. The resulting catalyst exhibits a hollow polyhedral structure with high surface area and porosity. Crucially, heteroatoms S and P were successfully incorporated into the primary coordination shell of Ni active sites, forming Ni-S and Ni-P bonds that modulate the electronic structure. Electrochemical tests revealed that Ni/NSP-C exhibits efficient ECR performance: a high current density of 402.3 mA cm -2 at -1.5 V vs. RHE, and CO Faradaic efficiency above 94 % over a wide potential window (-0.4 to -1.2 V), reaching 99.61 % at -0.8 V. The catalyst also demonstrated excellent stability over 24 h. Density functional theory (DFT) calculations further revealed that the S and P co-doping lowers the energy barrier for *COOH formation and suppresses the hydrogen evolution reaction, thereby enhancing ECR selectivity and efficiency. This work provides a universal coordination engineering strategy for optimizing the performance of single-atom catalysts in various electrocatalytic applications.

Polyanionic positive electrodes with XO 4 (X = P, S, Si etc.) tetrahedra exhibit beneficial properties, making them crucial for energy storage systems. However, strong covalent X-O bonds cause electron localization, reducing intrinsic electronic conductivity and limiting rate performance. Here we show a strategy to directional design the covalency of X-O bonds for enhanced intrinsic electronic conductivity of polyanionic positive electrodes. We developed a non-equilibrium fast calcination technique to synthesize polyanionic positive electrodes inheriting weak covalent (WC) X-O bond characteristics from screened precursor. In as-synthesized NASICON-Na 3 V 2 O 1.6 (PO 4 ) 2 F 1.4 as proof-of-concept positive electrode, the WC P-O bonds effectively activate electron delocalization, thereby increasing electrons transport capability along V-O-P-O-V pathway. The intrinsic electronic conductivity of optimised material achieves 3.57 times enhancement, leading to 3.70 times and 3.86 times improvement in specific capacity and specific energy at 50 C. Meanwhile, the optimised material exhibits capacity retention of 85.9% after 3000 cycles at 1 C. This study potentially opens up a broad space for improving the intrinsic conductivity of polyanionic materials (such as phosphates, sulfates, silicates, etc.), with the potential to promote the development of next-generation high-power positive electrode.

Fenton-like oxidation is a widely used advanced oxidation processes (AOPs) for the removal of persistent organic compounds. However, its development is significantly constrained by low H 2 O 2 utilization, the loss of transition metal ions, and the presence of harsh acidic conditions. Herein, a catalyst composed of MgO supported on porous P-doped graphitic C 3 N 4 (P-CN) was fabricated using a straightforward stepwise calcination process. The catalyst exhibited excellent performance in catalyzing the degradation of tetracycline (TC) through activated H 2 O 2 in the dark. The maximum reaction rate constant of the synthesized catalyst for TC degradation was 0.034 min −1 , which was nearly 62 times that of MgO and 18 times that of CN. The enhancement of catalytic properties was attributed to the doping of g-C 3 N 4 by P and the N-Mg bonds formed between g-C 3 N 4 and MgO, which not only enhanced charge transfer capabilities but also promoted the conversion of H 2 O 2 into 1 O 2 , •OH, and •O 2 − , thereby benefiting the degradation of pollutants. The effects of various parameters, including catalyst dosage, pH level, common interfering substances, and H 2 O 2 and TC concentrations, on degradation efficiency were examined in detail, and the ecological risk associated with the catalytic degradation of TC was predicted. In addition, the MgO/P-CN catalyst exhibited high stability, low H 2 O 2 consumption, and a broad pH range, had no transition metal components, and did not require an external energy input, demonstrating potential for the removal of organic pollutants and toxic waste.

The development of efficient photoelectrochemical (PEC) sensing materials for the food additive carmine (CRM) remains a significant challenge, with no PEC sensor reported for CRM to date. Herein, we reported the first PEC sensor based on an Sb 2 WO 6 /CuO p-n heterojunction for CRM detection. The heterojunction interface facilitated efficient charge separation through an internal electric field, as elucidated by density functional theory calculations. The detection mechanism relied on the specific binding between the carboxyl and hydroxyl groups in CRM molecules and the metal sites on the CuO surface. This interaction blocked the active sites, inhibited hole transfer, and led to a significant decrease in photocurrent. The sensor exhibited a wide linear range (0.4 - 500 μM), a low limit of detection (0.19 μM), and excellent stability (>96.74%). Furthermore, its successful application in beverage samples yielded recovery rates of 97.30 - 101.50%. This work provides a novel PEC platform for sensitive food additive monitoring.

By blending P(VDF-TrFE) with PVDF-HFP and introducing a small amount of ZnO, a composite film system with both mechanical flexibility and electrical responsiveness was constructed. The effects of the TrFE/HFP ratio and hot rolling temperature on the mechanical behavior and strain-induced electrical response of the films were systematically studied. The results show that the introduction of HFP improves film ductility, while a higher TrFE content enhances load bearing capability and electrical response. Among the investigated compositions, the TrFE80/HFP20 composite containing 1.08 wt % surface-modified ZnO showed a good balance between electrical response and mechanical compliance. After hot rolling, the films processed at 65 °C showed stable mechanical behavior at low to moderate strain and produced clear open circuit voltage signals under stretching. Clear electrical signals were also observed under thermal perturbation. Based on these results, the selected composite film was used to fabricate flexible strain sensors, demonstrating promising potential for practical applications.

Electrochemical nitrate reduction to ammonia (NO 3 RR)
is a sustainable strategy that integrates environmental remediation
with ammonia resource recovery. Current NO 3 RR studies mainly
focus on high nitrate concentrations under idealized electrolyte conditions
to achieve high ammonia yields. Under realistic water conditions,
low NO 3 – concentrations, neutral media,
and competing side reactions often result in sluggish kinetics, low
removal efficiency, and undesirable nitrite accumulation. Herein,
we report a facile strategy for constructing an interface-tunable Cu/Cu 2 O@CoO-P heterojunction
through one-step regulation of the growth of CoO nanoneedles on copper
mesh by tuning the phosphorus concentration. Phosphorus incorporation
effectively modulates the electronic structure of the Co active sites
and tunes the heterojunction interface, thereby optimizing the generation
of adsorbed hydrogen (*H) and suppressing the hydrogen evolution reaction.
This enables a well-matched two-step tandem pathway, where Cu/Cu 2 O facilitates the conversion of NO 3 – to NO 2 – , and the P-modulated CoO sites
rapidly hydrogenate NO 2 – to NH 4 + , thus effectively preventing excessive NO 2 – accumulation. The optimized Cu/Cu 2 O@CoO-P achieves a high Faradaic efficiency
(FE) of 97.11% for NH 4 + - N and an ammonia yield
of 36.09 mg h –1 cm –2 at 10 mA
cm –2 under neutral-pH conditions, along with excellent
stability, retaining 98.45% of its performance after 20 cycles. Notably,
the catalyst demonstrates exceptional practical applicability for
ammonia recovery from real aquaculture tailwater in both batch mode
and continuous-flow mode. This work offers new insights into the design
of tunable heterojunction interfaces to achieve a well-matched and
efficient tandem catalytic process, enabling effective remediation
of low-concentration nitrate contamination and high ammonia recovery
in real wastewater environments.

ZnO nanowire in-situ growth on cotton textiles via interface coordination strategy. • Self-activating electro-mechanical intervention for high antibacterial properties. • Modified textiles maintain above 95% against bacteria and viruses after 50 washings. • The antibacterial and antiviral function can be activated by mild finger pressure. The risk of bacterial infection and transmission via textiles has escalated into a significant public health crisis. Herein, self-activated electro-mechanical intervention based on ZnO nanowires was applied to confer high antibacterial efficiency on the textile. This study proposes an interfacial coordination strategy, in which the pre-coordinated Zn 2+ ions on cellulose induce the in-situ growth of a uniform and stable ZnO seed layer on cotton textiles (CTs), thereby enabling the subsequent in-situ growth of Li‑doped ZnO nanowires (Li-doped ZnO nanowires and ZnO seed layer were constructed as a p-n homojunction). The functionalized CTs (LZnO/CTs) generate dual electric fields (piezoelectric field and the built-in field at the p-n junction) under piezoelectric response to induce continuous electron depletion in bacteria; while the nanowire structure enables physical piercing of bacterial membranes to achieve antibacterial purposes. LZnO/CTs showed superior efficient inhibition of E. coli (99.56%), S. aureus (97.19%), and MS2 (99.99%) within 2 min, respectively, via electro-mechanical. Moreover, the modification process preserves the intrinsic physical properties of the textiles, and the sterilization functionality can be readily activated by mild finger pressure. The highly efficient antibacterial and antiviral functional surface on cotton textiles demonstrates substantial practical application potential in personal wearable devices and medical environments.

The efficiency of strain-mediated magnetoelectric (ME) coupling is fundamentally governed by the fidelity of stress transfer across the interface between magnetostrictive and piezoelectric phases. In polymer-based nanocomposites, however, mechanical energy is often dissipated due to viscoelastic damping at interfaces, which severely limits the energy transduction efficiency. Herein, we fabricated flexible P(VDF-TrFE)-based ME nanocomposites through an intrinsically anchored strategy to enhance the interfacial stress transfer. By directing the growth of magnetic CoFe 2 O 4 on self-assembled s PPTA/BTAc aromatic backbones, we created intrinsically anchored magnetic nanofibers (IAM NFs) with skeleton-integrated nanostructure. In this geometric-chemical hybrid structure, molecular templates are interwoven with the magnetic phase, providing an aromatic backbone for direct stress conduction and abundant functional groups for molecular-level interlocking with polymer chains. Consequently, the composite achieves highly efficient strain-mediated ME coupling of 42.8 mV·cm −1 ·Oe −1 at an exceptionally low filler content of 1 wt%. By optimizing interfacial efficacy rather than increased filler content, the ME nanocomposite films maintain exceptional lightweight and flexibility, evidenced by breaking elongation of 23.3%. This work provides a strategic pathway for developing high-performance, lightweight, flexible electronics through rational interfacial engineering and morphological control.

Chronic neuropathic pain is sustained by nerve injury-induced central sensitization and is characterized by both sensory and affective manifestations. However, its underlying neural circuit mechanisms remain to be fully elucidated. Here, we revealed that CaMKII-expressing neurons in the parasubthalamic nucleus (PSTN) were recruited and exhibited hyperactivity in a neuropathic pain mouse model, established via spared nerve injury of the sciatic nerve (SNI). Optogenetic and chemogenetic inhibition of PSTN CaMKII neurons alleviated hyperalgesia and induced conditioned place preference (CPP) in SNI mice, without altering pain thresholds in sham mice. Mechanistically, we demonstrated that PSTN neurons received monosynaptic glutamatergic inputs from tachykinin precursor 1 (Tac1)-expressing neurons in the lateral parabrachial nucleus (LPB), and were excited by glutamate and substance P (SP) co-released from this projection. Inhibition of the LPB–PSTN projection recapitulated the analgesic and CPP-inducing effects of direct inhibition of PSTN neurons in SNI mice. Notably, these therapeutic effects were mimicked by local administration of a neurokinin receptor 1 (NK1R) antagonist, but were reversed by intra-PSTN injection of SP. Together, this study not only establishes the involvement of the LPB–PSTN circuit and local NK1R in the pathophysiology of neuropathic pain but also demonstrates their promise as therapeutic targets.

The rational design and facile synthesis of non‑platinum carbon catalysts with high energy conversion efficiency remain a core challenge in electrocatalysis. To address this, we successfully constructed a unique shell-in-shell catalyst through a phytic acid (PA) etching and secondary pyrolysis strategy, designated as CZIF-PA-Fe 2 P/NC. In this process, PA not only drives the selective etching of cubic ZIF-8 nanocrystals but also serves as an in situ phosphorus source to induce the uniform nucleation of highly active Fe 2 P nanoparticles embedded in ZIF-derived N,P-codoped carbon nanoboxes. Consequently, the obtained CZIF-PA-Fe 2 P/NC catalyst achieves an excellent oxygen reduction reaction (ORR) half-wave potential of 0.914 V, and maintains a 96.73% current retention over a 30-h stability test. When assembled into zinc-air batteries, the device delivers a peak power density of 157.58 mW cm −2 , a specific capacity of 795.76 mAh g −1 , and long-term cycling stability surpassing that of 20 wt% Pt/C. Finally, density functional theory calculations reveal that the synergistic electronic modulation between the N,P-codoped carbon substrate and Fe 2 P promotes an upward shift of the Fe d -band center, thereby optimizing the adsorption of key *OOH intermediates and significantly reducing the energy barrier of the rate-determining step. This work establishes a precise morphology design and interface engineering paradigm for developing cost-effective, high-performance metal-organic framework-derived non-noble-metal carbon electrocatalysts for energy conversion and storage applications. The selective etching of phytic acid not only endows the material with abundant pore diameters to enhance mass transfer but also serves as an in-situ phosphorus source to promote the uniform nucleation of highly active Fe 2 P nanoparticles. By employing PA-induced etching, shell-in-shell carbon catalysts were successfully fabricated to exhibit satisfactory oxygen reduction.

Noble-metal-based electrocatalysts have long been the top choice for hydrogen evolution reaction (HER) electrocatalysts, offering low overpotentials and Tafel slopes. Nonetheless, their use in alkaline media has been limited due to the sluggish kinetics of the Volmer process. Herein, we develop a unique biomass-derived heteroatom-doped porous carbon material via self-templating to anchor ruthenium‑molybdenum carbide (Ru-Mo 2 C) nanoclusters. The synthesized Ru-Mo 2 C-supported heteroatom-doped porous carbon (RuMo-NPCSPC) shows exceptional electrocatalytic ability for alkaline HER, achieving low overpotentials of 49, 85, and 92 mV to realize 10 mA cm −2 in 1 M KOH, alkaline seawater, and simulated alkaline seawater, respectively. The RuMo-NPCSPC also boasts low Tafel slopes and ultrahigh Faradaic Efficiencies (98–100 %) in alkaline media, outperforming most noble metal-based catalysts and mercantile Pt/C. Most importantly, the catalyst demonstrates outstanding stability, signifying its potential for industrial hydrogen production. This work delivers profound perspectives into synthesizing advanced nanostructured porous carbon materials using abundant biomass resources for alkaline HER.
