The development of highly efficient photocatalysts for solar-driven hydrogen evolution is critically important for addressing global energy and environmental challenges. In this study, a dual-vacancy system comprising cooperatively interacting sulfur vacancies (V S ) and indium vacancies (V In ) was constructed in ZnIn 2 S 4 (ZIS) through a combined hydrothermal-acid etching strategy. This approach enabled site-selective enrichment of the two distinct vacancies within the [ZnS] 4 and [InS] 4 structural units, respectively, leading to the increment of the active sites for catalytic reaction. Systematic characterization and theoretical calculations confirm that the unique vacancy configuration induces a substantially enhanced built-in electric field (BIEF), oriented from the n-type V S region toward the p-type V In region, which effectively promotes spatial separation and directional migration of photogenerated electron-hole pairs while significantly suppressing non-radiative recombination. The optimized ZIS catalyst with dual-vacancies (ZIS-D) achieves an exceptional hydrogen evolution rate of 9.68 mmol·h −1 ·g −1 under simulated solar illumination, representing 7-fold and 4-fold enhancements compared to pristine ZIS and ZIS-V S samples, respectively. This study provides new perspectives and theoretical foundations for vacancy engineering in the design of advanced photocatalytic systems.

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.

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.

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.

To meet the growing requirement for highly integrated electronic systems, nanocomposites comprised high dielectric constant ( ε ) ceramic nanofillers and large dielectric breakdown strength ( E b ) polymer has been widely investigated for high energy density capacitor. However, the poor interfacial compatibility arising from the great difference of surface energies and ε values usually resulted to the sacrifice of the dielectric properties and thus the capacitive performance. In this work, a series of core-shell structured barium titanate (BaTiO 3 ) nanofillers were designed and prepared to address this challenge via surface-initiated atom transfer radical polymerization (SI-ATRP) of methyl methacrylate (MMA), ethyl methacrylate (EMA) and glycidyl methacrylate (GMA). BaTiO 3 @PMMA (BT@M), BaTiO 3 @PEMA (BT@E), BaTiO 3 @PGMA (BT@G) were fabricated and incorporated into poly (vinylidene fluoride- co -hexafluoropropylene) (P(VDF-HFP), PVH), respectively. Enhanced dielectric properties, E b , and energy storage density were observed in these nanocomposites comparing with nanocomposites of BT/PVH. It should be ascribed to the polymer shell layer alleviated the great surface energy and ε value disparity between BT filler and PVH matrix, which was responsible for the enhancement of the interfacial compatibility and homogenous distribution of electric fields. Among these three types of nanocomposites, PVH/BT@G exhibited superior dielectric properties and capacitive performance. Extraordinary advances in charge carrier suppression at elevating temperature and electric field were also witnessed in PVH/BT@G. It should be attributed to the polar PGMA layer served as the deep traps, which block the charge motion in the filler-matrix interfaces. At optimal conditions, energy density of 10.61 J cm −3 and efficiency of 65.7 % at 360 MV m −1 was achieved. This work may provide insight into the rational design of the shell layer of the fillers for polymer nanocomposites dielectrics.

Based on the Na 0.48 La 0.52 MoO 4 ceramic, this study replaced La 3+ ions with Nd 3+ ions through ion substitution, which significantly increased the Q × f of Na 0.48 La 0.52 MoO 4 and reduced the sintering temperature. The good sintering state of this series of ceramics was demonstrated by scanning electron microscopy (SEM) and density tests. X-ray diffraction (XRD) and Raman spectroscopy results revealed the formation of solid solutions without the presence of secondary phases or impurities. The P–V–L theory indicated that the Na/La/Nd–O bond-to-bond ionicity (fi) contribution was dominant, while the Mo–O bond also played a significant role in the lattice energy ( U ), bond energy ( E ), and thermal expansion coefficient ( α ). Among them, the Na 0.48 La 0.48 Nd 0.04 MoO 4 ceramic achieved the best dielectric performance at 900 °C, with ɛ r = 11.027 ± 0.018, Q × f = 113,805 ± 6,358 GHz, and τ f = − 23.36 ppm/℃. Through ion substitution, these materials all have low sintering temperatures and high Q × f values, making them ideal candidates for low-temperature co-fired ceramics (LTCC).

With the rapid development of 5G/6G mobile communication technology, microwave dielectric materials are facing increasingly strict performance requirements. As core fundamental materials for modern communication systems, performance optimization of microwave dielectric ceramics has become a research hotspot. Addressing the limitations of single-phase ceramic materials, dense microwave dielectric ceramics of (Nd 1- x La x ) 2 [Zr 0.89 (Bi 0.5 Ta 0.5 ) 0.11 ] 3 (MoO 4 ) 9 ( x = 0.01, 0.03, 0.05, 0.07) were prepared by the conventional solid-state reaction method. The experimental process involved 550 °C pre-sintering followed by gradient sintering at 600–725 °C (4 h holding time). X-ray diffraction (XRD) analysis confirmed that all samples exhibited trigonal crystal structure with \(R\overline{3} c\) space group. The lattice parameters were obtained by Rietveld refinement method. Scanning electron microscopy (SEM) characterization indicates that compactness has a significant impact on the dielectric constant ( ε r ) and the quality factor ( Q × f ). Raman spectroscopy analysis indicated strong associations of ε r and Q × f values with characteristic peak shifts and full width at half maximum ( FWHM ), respectively. When sintered at 675 °C, the NLZBTM ( x = 0.03) ceramics exhibited exceptional comprehensive performance: ε r = 11.24 ± 0.02, Q × f = 116,914 ± 5738 GHz, and τ f = − 37 ± 1.5 ppm/℃. The bond property analysis based on the P–V–L theory shows that the ionicity of the Nd/La–O bond makes the greatest contribution to εᵣ , while the covalency of the Mo–O bond significantly affects the Q × f value and τ f parameter. It is noteworthy that this material achieves low-temperature sintering at 675 °C while maintaining excellent microwave dielectric properties, demonstrating significant potential as a candidate material for low-temperature co-fired ceramics (LTCC).

Developing sustainable carbon materials with both dye adsorption and electrochemical properties offers a promising strategy for carbon neutrality. Herein, a coupled carbonization strategy was employed to prepare porous carbon with high-level heteroatom doping and hierarchical pores, involving the co-hydrothermal treatment of wood flour with phytic acid and melamine, followed by K 2 CO 3 activation. Phytic acid and melamine act as P/N sources and structural builders, promoting hydrochar formation via phosphate coordination and condensation reactions, resulting in a stable cross-linked network rich in N, P, and O. The resulting N, P co-doped hierarchical porous carbon (NP-PC) exhibits an ultrahigh surface area (2792 m 2 g −1 , a 344 % increase compared to pure wood flour-derived carbon), suitable mesoporosity (36 %), and tailored surface chemistry (19.86 at% heteroatom content). At room temperature, NP-PC demonstrates an exceptionally high adsorption capacity for methylene blue (3028 mg g −1 after 6 h contact) and rapid adsorption kinetics (90 % removal within 5 min), outperforming most reported carbon-based adsorbents. NP-PC retains an adsorption capacity above 2500 mg g −1 even after five regeneration cycles. As a supercapacitor working electrode, NP-PC electrode also shows excellent electrochemical performance, delivering a specific capacitance of 380 F g −1 at 0.5 A g −1 and retaining 273 F g −1 at 25 A g −1 . This study achieves the conversion of low-value biomass into high-performance functional carbons, providing a sustainable solution for integrated environmental and energy applications.

p -Cresol plays a pivotal role in shaping the flavor quality of suansun . This study examined the effect of inoculating Levilactobacillus zymae KUST4216, a high p -cresol-producing strain, on the fermentation of suansun . Comparative analyses between uninoculated and inoculated fermentation revealed that both followed similar acidification patterns, but inoculated fermented suansun accumulated significantly more p -cresol (6.62 ± 4.15 mg/kg vs. 0.20 ± 0.14 mg/kg). Inoculation with L. zymae KUST4216 rapidly established microbial dominance, reshaped community succession, and promoted early sugar utilization. Genomic analysis showed enrichment in carbohydrate and amino acid metabolism and abundant CAZymes, supporting efficient precursor supply for aromatic compound biosynthesis. Transcriptomic profiling confirmed coordinated regulation that directed metabolic flux toward p -cresol synthesis. Overall, L. zymae KUST4216 drives p -cresol formation via the tyrosine pathway and stabilizes fermentation ecology, providing mechanistic insight into flavor generation and offering a strategy for enhancing the sensory quality of fermented bamboo shoots through targeted microbial inoculation.
