While constructing hierarchical structures is an effective strategy to boost hydrogen evolution reaction (HER) activity, most existing synthesis routes still rely on high-temperature treatments. Herein, a novel 1D/2D/0D hierarchical NiMoO 4 /Ni(OH) 2 @P–Ni electrocatalyst is fabricated on nickel foam via a simple and mild two-step method involving hydrothermal synthesis and subsequent electrodeposition. The catalyst requires an overpotential of 77 mV to achieve a current density of 10 mA cm −2 for the alkaline HER and operates stably for 100 h. The high performance originates from a well-orchestrated synergy: P–Ni nanoparticles serve as highly active sites for hydrogen adsorption, while the Ni(OH) 2 component and the multi-component heterointerfaces collectively facilitate water dissociation and charge transfer. Moreover, the hierarchical structure imparts exceptional interfacial properties, including superhydrophilicity and efficient gas bubble release. This work offers a viable strategy for designing high-performance electrocatalysts by orchestrating multi-component synergy within a rationally engineered hierarchical architecture.

The development of rechargeable zinc–air batteries is critically hindered by the sluggish kinetics of both the oxygen reduction and the oxygen evolution reaction. For advancing zinc–air battery technology. The effective design of bifunctional catalysts that efficiently facilitate both the oxygen reduction and oxygen evolution reactions is crucial for advancing the development of zinc–air batteries. Overcoming the intrinsic sluggish kinetics of oxygen electrocatalysis remains a fundamental challenge that limits the commercial viability of rechargeable zinc–air batteries. Herein, the work proposes a rational strategy to construct a three-phase heterogeneous interface: Co7Fe3/Co/Co2P@NPCNT was successfully synthesized by a two-step pyrolysis using CoFe–FF as the precursor and dicyandiamide and sodium hypophosphite as carbon, nitrogen, and phosphorus sources, respectively. The half-wave potential (E1/2) of Co7Fe3/Co/Co2P@NPCNT is 0.85 V, and the overpotential (η10) is 295 mV at 10 mA cm–2. Comparative evaluation confirms that the catalytic activity of Co7Fe3/Co/Co2P@NPCNT is superior to those of Pt/C and RuO2. The catalytic activity of Co7Fe3/Co/Co2P@NPCNT is superior to that of Pt/C and RuO2. Meanwhile, the zinc–air batteries assembled by Co7Fe3/Co/Co2P@NPCNT have an open-circuit voltage of 1.45 V, a peak power density of 130 mW cm–2, and a large specific capacity. The structure of carbon nanotubes not only facilitates the dispersion of metal nanoparticles but also increases the active sites. Moreover, the corrosion of nanoparticles by alkaline electrolyte is reduced, and the stability is enhanced. The good bifunctional catalytic activity of Co7Fe3/Co/Co2P@NPCNT can be attributed to the synergistic effect of electron transfer between the three-phase interfaces and the multicomponent active centers (alloy, phosphide, N, P-codoped carbon nanotubes). In this work, the three-phase heterogeneous interface is constructed reasonably. This unique structure improves the catalytic activity and provides a new idea for the design of bifunctional catalysts.

The rational design of heterostructured electrocatalysts with efficient charge transfer pathways is crucial for advancing sustainable water-splitting technology. In this work, a bimetallic Co 2 P/Fe 2 P heterojunction catalyst is successfully synthesized on nickel foam (NF) through a hydrothermal method followed by controlled phosphorization. The heterointerface between Co 2 P and Fe 2 P induces a strong built-in electric field (BEF) due to their distinct Fermi level alignment, as confirmed by Mott-Schottky analysis and Kelvin probe force microscopy (KPFM). This BEF gives rise to electron-deficient Co regions and electron-enriched Fe regions near the heterointerface, which is expected to modulate the local electronic structure and facilitate interfacial charge transfer, thereby benefiting the overall HER/OER kinetics. The as-prepared Co 2 P/Fe 2 P@NF exhibits exceptional bifunctional activity in alkaline media, achieving low overpotentials of 109 mV for the hydrogen evolution reaction (HER) and 165 mV for the oxygen evolution reaction (OER) at 20 mA cm −2 , with Tafel slopes of 54.8 mV dec −1 and 31.5 mV dec −1 , respectively. A two-electrode electrolyzer assembled with Co 2 P/Fe 2 P@NF as both anode and cathode requires only 1.50 V to deliver 20 mA cm −2 , surpassing most reported non-noble metal catalysts. Systematic characterizations (XPS, TEM, EIS) reveal that the hierarchical nanoplate structure with abundant heterointerfaces provides a high electrochemical surface area (17.4 mF cm −2 ) and facilitates electrolyte penetration. Moreover, the catalyst exhibits outstanding long-term durability, retaining at least 98% of its initial performance after 20 h of continuous operation at 20 mA cm −2 under both oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) conditions. This work highlights the pivotal role of interfacial BEF engineering in developing high-performance electrocatalysts for practical water-splitting applications.

Background Leucine aminopeptidase (LAP) is a promising biomarker for the detection and diagnosis of liver diseases encompassing liver cancer and liver injury. Existing assays for LAP activity have limitations, as most of them rely on substrates that are cumbersome to synthesize and fail to amplify the detection signal. Results Initially, L-pAP was synthesized to serve as a substrate for LAP through the condensation of p -aminophenol (pAP) with leucine. LAP triggered the hydrolyzation of L-pAP into pAP, which then reduced colourless Fe 3+ -ferrozine to purple Fe 2+ -ferrozine. Upon addition of tris(2-carboxyethyl)phosphine, the oxidation product p -quinone imine was quickly converted to pAP, which then continuously reduced Fe 3+ -ferrozine to produce substantial amounts of Fe 2+ -ferrozine that could be readily detected as purple using a commercial microplate reader or visual observation. The findings showed that the redox-cycling process greatly lowered the detection limit of LAP to 0.1 U/L, representing 2 orders of magnitude improvement over conventional detection methods. Moreover, we further expanded the feasibility of the proposed process to the assessment of LAP activity in cancer cell lysate. Significance and novelty This work introduces a novel LAP detection method characterized by simple substrate synthesis and high sensitivity. The detection limit of LAP was reduced through the signal amplification strategy of redox cycling. Our research findings provide a powerful chemical tool for LAP detection, offering enormous potential for future biomedical research and diagnosis of related diseases.

Poly(vinylidene fluoride) (PVDF)-based ferroelectrics are essential for film capacitors, yet their high dielectric loss and low charge/discharge efficiency caused by ferroelectric hysteresis severely limit practical applications. Linear polypropylene (PP), in contrast, dominates the commercial capacitor market due to its high efficiency and low loss, prompting extensive efforts to combine the advantages of both polymers. However, existing approaches often rely on costly molecular design or complex film-forming processes, conflicting with the demands for low-cost and miniaturized electronic devices. Here, we report a solution-based and scalable strategy that avoids high-temperature melt processing to fabricate a hybrid dielectric film comprising a P(VDF-HFP) matrix, embedded PP chain segments, and core–shell structured BT@SiO2 nanoparticles. Polypropylene chain segments are embedded into the poly(vinylidene fluoride-co-hexafluoropropylene) [P(VDF-HFP)] matrix via solution blending, forming molecularly interpenetrating interfaces that effectively suppress ferroelectric hysteresis. Core–shell structured BT@SiO2 nanoparticles are simultaneously incorporated to further enhance dielectric properties. The resulting P(VDF-HFP)-PP/BT@SiO2 nanocomposite films exhibit a high dielectric constant of 46, a charge/discharge efficiency consistently exceeding 80%, and a maximum energy density of 3.92 J/cm3. Phase-field simulations further reveal that the P(VDF-HFP)-PP/BT@SiO2 architecture with graded dielectric constants mitigates local electric field concentration, accounting for the excellent breakdown performance. Unlike conventional high-temperature melt processing or complex molecular design, this work offers a low-cost and scalable route that avoids high-temperature melt processing to high-performance polymer dielectrics, demonstrating that combining molecular interpenetration with core–shell filler engineering provides a promising pathway for next-generation capacitors.

Two different liquid membrane systems were developed for efficient extraction of hydrophilic peptides. • The mass transfer mechanisms for conventional organic and DES-based liquid membranes were systematically elucidated. • A high-throughput 96-well electromembrane extraction platform was established for urinary peptide analysis. • A novel Log P-charge dual-factor model was proposed to predict peptide electromigration behavior in EME systems. The selective enrichment of trace hydrophilic peptides from complex biological matrices remains a pivotal challenge in biomarker discovery. To address this, we developed a high-throughput and environmentally friendly electromembrane extraction-liquid chromatograph/mass spectrometry (EME-LC/MS) method for the analysis of 21 hydrophilic endogenous peptides in urine. Two different liquid membranes were optimized: P1, a conventional organic liquid membrane consisting of 2-nitrophenyl octyl ether (NPOE) and carvacrol (2:1, v /v ) with 2% di(2-ethylhexyl) phosphate (DEHP); and P2, a deep eutectic solvent (DES)-based membrane composed of camphor and decanoic acid (1:1, w /w ) with 0.5% DEHP. Mechanistic studies revealed that P1 extraction relies on cation-π, π-π stacking, and ion-pair interactions, enriching 13 peptides within 20 min at 30 V. In contrast, P2 operates via hydrogen bonding and ionic interactions, achieving more rapid extraction of 14 peptides within only 10 min at 30 V, along with a broader operational window and enhanced green solvent potential. Importantly, we established a log P -charge dual-factor model, demonstrating that peptide electromigration was co-determined by lipophilicity (log P ) and net charge under operational buffer, with its predictive reliability confirmed by external validation. Implemented in a 96-well format, the EME method was high-throughput, solvent-minimized, and environmentally friendly with AGREEprep score of 0.72. Beyond providing a robust analytical tool, this work established a fundamental mechanistic framework for the design of electromembrane extraction systems, advancing both biomarker analysis and the understanding of transmembrane transfer for polar biomolecules.

The persistence of fluoroquinolone antibiotics like OFL in aquatic environments poses a significant ecological and public health risk due to their poor biodegradability and potential to induce antibiotic resistance. This study reports the fabrication of free-standing, flexible nanofibrous films via electrospinning, incorporating optimal BGFZ9 nanoparticles into a P(VDF-HFP) matrix (denoted as P(VDF-HFP)@BGFZ9). Comprehensive characterization reveals that the BGFZ9 nanoparticles act as effective heterogeneous nucleating agents, significantly promoting the formation of piezoelectric β-phase in P(VDF-HFP) and enhancing the ferroelectric polarization of the composite through interfacial coupling. Under ultrasonic excitation, the composite film exhibits remarkable piezocatalytic performance for OFL degradation, following pseudo-first-order kinetics. The film with an optimal 10% BGFZ9 loading achieves a reaction rate constant of 0.684 min–1·g–1 under piezocatalysis, which is approximately 1.22 times higher than that of the pure polymer film. A synergistic piezophotocatalytic effect is observed under combined ultrasonic and light irradiation, leading to an OFL removal efficiency of 85.71% within 3 h and a further increased rate constant of 1.043 min–1·g–1. Radical scavenger experiments and EPR spectroscopy identify superoxide radicals •O2– and h+ as the primary reactive species responsible for the degradation. The composite film demonstrates excellent cycling stability, retaining 94.4% of its initial activity after five consecutive runs, alongside robust structural integrity. This work provides a novel strategy for developing efficient, stable, and easily recyclable flexible piezocatalytic materials for antibiotic wastewater remediation.

Due to the high potential property (≥3.5 V vs Li/Li + ), p-type organic electro-chemical active materials (OEAMs) have attracted increased attention to constructing high-voltage cathodes for lithium organic batteries (LOBs). However, small-molecule p-type OEAMs face severe electrolyte dissolution. Herein, we develop a phenothiazine-based hypercrosslinked polymer (PZ-X) via Friedel–Crafts chemistry to inhibit dissolution. More importantly, to optimize micro-nano morphology with conductive agent of carbon nanotubes (CNTs), an in situ synthesized PZ-X@CNTs composite cathode is proposed. Characterizations confirm PZ-X@CNTs' effective π-π interactions and favorable nanocomposite morphology. The PZ-X and PZ-X@CNTs cathodes deliver ≈120 mAh g −1 at 2.0–4.5 V. Notably, the in situ synthesized PZ-X@CNTs cathode exhibits superior rate capability and cycling stability. This work provides valuable guidance for in situ constructing high-performance p-type OEAMs with fine micro-nanostructures for high-voltage LOBs.

The formulation and improvement of high-efficiency lubricant additives on the basis of novel two-dimensional MXene materials have drawn increasing attention in recent years. Herein, we report the synthesis of N, P doped Ti 3 C 2 T x MXene using ammonium hypophosphite as the N/P source, followed by surface modification with catechol-containing ionic liquid to obtain ionic liquid-functionalized MXene. Tribological tests reveal that ILs@N, P‑MXene markedly improve the tribological properties of 500SN with 0.75 wt% addition. Compared with the lubricant 500SN, the mean COF is reduced to 0.107, the wear volume decreases by 65.8%, and their load-carrying ability is improved to 650 N from 150 N. XPS analysis indicates that ILs@N, P-MXene undergoes tribochemical reactions with the steel substrates during sliding, forming a continuous and stable protective tribofilm comprising carbonitrides, iron oxides, titanium oxides and iron phosphates. This in-situ formed tribofilm successfully inhibits direct asperity contact between the mating surfaces, thereby endowing the lubricant system with good load-carrying capacity and improved tribological performance.

The double-shell P (MMA-MPS)/SiO 2 /CeO 2 composite abrasive was designed and prepared through the soap-free emulsion polymerization, the sol–gel method, and the in situ chemical precipitation method. Take 3-(methacryloyloxy)propyltrimethoxysilane-modified methyl methacrylate (P (MMA-MPS)) microspheres as the core. The a SiO 2 and b SiO 2 inner shells were coated on the core in acidic and alkaline environments, respectively. The CeO 2 outer shell was then deposited on the inner shell. The morphology, structure, and chemical mechanical polishing performance on KDP crystals of composite abrasives were characterized using SEM, TEM, XRD, FTIR, XPS, and AFM. The results indicate that the P (MMA-MPS)/ a SiO 2 /CeO 2 abrasive possesses the “loose net-like” inner shell of a SiO 2 with the positive charge (-Si-OH 2 + ), leading to the sparser outer shell of CeO 2 and the expanded CeO 2 lattice. After polishing, the surface roughness (Ra) of KDP crystal is 0.69 nm, and the material removal rate (MRR) is 125.6 nm/min. The P (MMA-MPS)/ b SiO 2 /CeO 2 abrasive possesses the “dense strawberry-like” inner shell of b SiO 2 with the negative charge (-Si-O − ), which facilitates the uniform deposition of Ce 3+ through electrostatic adsorption, and forms the dense, complete and highly crystalline outer shell of CeO 2 . The proportion of Ce 3+ is increased by 2.5%. After polishing, the Ra of the KDP crystal further decreases to 0.43 nm, and the MRR increases to 146.2 nm/min. In summary, the comprehensive performance of the P (MMA-MPS)/ b SiO 2 /CeO 2 abrasive is superior to that of the P (MMA-MPS)/ a SiO 2 /CeO 2 abrasive.

C@MoS 2 @Ag 2 S heterojunction nanozyme was constructed. • C@MoS 2 @Ag 2 S presented exceptional peroxidase-like activity. • p-nitrophenol was efficiently degraded by C@MoS 2 @Ag 2 S through activating H 2 O 2 and PDS. In this study, a carbon-coated MoS 2 @Ag 2 S (C@MoS 2 @Ag 2 S) heterojunction nanozyme with superior peroxidase-like activity is prepared via heterojunction pre-construction followed by carbonization. The kinetic parameters toward H 2 O 2 are determined to be K m = 1.02 mM and V max = 38.08 × 10 −8 M·s −1 , and toward 3,3′,5,5′-tetramethylbenzidine (TMB) are K m = 0.14 mM and V max = 60.35 × 10 −8 M·s −1 . Notably, its affinity for H 2 O 2 is substantially higher than that of natural horseradish peroxidase (HRP, K m = 3.7 mM), and the catalytic efficiency (V max ) is also superior. Enhanced performance stems from three-component synergy improving electron transport, charge separation, and ROS generation. Through synergistically activating persulfate (PDS) and H 2 O 2 , SO 4 • ⁻ , •OH, and 1 O 2 are generated, which collectively degrade PNP, achieving 90% removal in 40 min. This study offers theoretical guidance for the controllable synthesis of biomass-derived carbon/metal sulfide heterojunction nanozyme and the design of dual-oxidant synergistic activation systems for degradation of organic pollutants.

Carbon dots (CDs) have emerged as promising room-temperature phosphorescence (RTP) materials for advanced anti-counterfeiting and encryption applications owing to their tunable emission and favorable biocompatibility. However, the simultaneous realization of multicolor phosphorescence, long lifetime, and dynamic color modulation within a single CDs-based system remains a significant challenge. Herein, a boric acid-crosslinked and silane-confined CDs system was constructed to investigate the roles of rigid-network confinement and the rhodamine B (RhB)-regulated phosphorescence Förster resonance energy transfer (P-FRET) in governing dynamic multicolor afterglow. Compared with the conventional aminopropyl silane (APTES)-derived network, the long-chain diamine silane (DAMO)-derived network provided additional amino sites and a rigid-flexible confinement environment, which enhanced n–π* transition processes and promoted intersystem crossing, thereby extending the phosphorescence lifetime from 106.37 to 448.87 ms. Phosphorescence spectroscopic analysis revealed that increasing the RhB content introduced low-energy acceptor centers, which enhanced the P-FRET process from CDs to RhB-related acceptors and enabled tunable afterglow emission from blue (480 nm) to red (595 nm). The shortened donor lifetime, time-resolved emission evolution, and reduced energy gap revealed by density functional theory (DFT) calculations collectively supported the T 1 -S 1 P-FRET process from CD donors to RhB related acceptors. The resulting time-dependent afterglow color evolution was further demonstrated in dynamic digital encryption, multicolor QR codes, and time-resolved logic-gate anti-counterfeiting. This work provides a rational strategy for designing dynamic CDs-based RTP materials through rigid-network confinement and energy-transfer engineering.
