Mg/Zr/Nb tri-doping jointly stabilizes Ni-rich layered cathodes under harsh operating conditions. • Tri-doping reduces Li + /Ni 2+ mixing and stabilizes the transition-metal layer and oxygen framework. • MZN-NCM delivers excellent cycling stability at room temperature, high temperature, and high cutoff voltage. • Mg/Zr/Nb co-doping improves charge transfer and Li + diffusion, enhancing the durability of Ni-rich cathodes. Ni-rich layered cathode materials (LiNi x M 1-x O 2 , x ≥ 0.8) offer high capacity and high energy density, but their cycling stability severely suffers from Li + /Ni 2+ cation mixing, H2-H3 phase-transition strain, interfacial side reactions, and sluggish Li + transport, especially under harsh conditions such as elevated temperature and high cutoff voltage. In this work, a Mg/Zr/Nb tri-doping strategy is proposed to construct Li(Ni 0.9 Co 0.05 Mn 0.05 ) 0.97 Zr 0.01 Mg 0.01 Nb 0.01 O 2 (MZN-NCM) cathode for synergistic stabilization under different operating conditions. The results show that Mg/Zr/Nb co-doping regulates the Ni valence distribution, reduces Li + /Ni 2+ cation mixing, enhances the stability of the transition-metal layer and oxygen framework, and suppresses interfacial side reactions and CEI degradation during cycling. MZN-NCM retains 90.1% of its capacity after 100 cycles at 25 °C and 89.8% at 60 °C, compared with only 59.8% and 41.7% for Pristine-NCM, respectively. Under a high cutoff voltage of 4.5 V, MZN-NCM also maintains a higher capacity retention of 87.7% after 100 cycles. Moreover, kinetic and interfacial chemical analyses indicate that multielement doping improves both charge-transfer behavior and Li + diffusion, enabling a synergistic enhancement of structural stability, interfacial stability, and ion transport. This work demonstrates that Mg/Zr/Nb synergistic doping is an effective material-design strategy for extending the applicable operating conditions of Ni-rich cathodes.

A PTFE-based composite with surface-modified Zr₂O(PO₄)₂ (ZOP) filler was developed for high-frequency applications. • FAS-17 surface modification improves tZOP-PTFE compatibility and filler dispersion while reducing visible defects. • PTFE@tZOP-40 exhibits an ultralow dielectric loss (D f = 5.5 ×10 −4 at 10 GHz) and a reduced CTE of 51.6 × 10 −6 K −1 . With the increasing demand for advanced dielectric materials in high-frequency microwave and millimeter-wave systems, polytetrafluoroethylene (PTFE) has attracted considerable attention due to its low dielectric constant, low dielectric loss, and excellent electrical insulation. However, its high coefficient of thermal expansion (CTE) may cause dimensional instability and reliability issues in high-frequency substrate applications. In this study, zirconium oxophosphate (Zr₂O(PO₄)₂, ZOP), an ultralow-CTE ceramic filler, was incorporated into the PTFE matrix to develop composites with reduced thermal expansion and favorable dielectric performance. To improve the compatibility between hydrophilic ZOP and hydrophobic PTFE, ZOP particles were surface-modified using a fluorinated silane coupling agent to obtain tZOP. The modified tZOP showed improved dispersion in the PTFE matrix and reduced visible defects, contributing to a denser composite microstructure and enhanced thermal dimensional stability. At a filler loading of 40 wt%, the PTFE@tZOP composite achieved a CTE of 51.6 × 10 −6 K −1 , a dielectric constant of 2.83, and a dielectric loss of 5.5 × 10 −4 at 10 GHz. This work demonstrates an effective surface-modification strategy for developing PTFE-based composites with low thermal expansion and favorable dielectric properties for next-generation high-frequency substrates.

Recently developed halide solid-state electrolytes (SSEs) have become promising alternatives for the next generation inorganic SSEs, primarily due to their comparatively favorable ionic conductivity, desirable deformability, and economic feasibility. Nevertheless, their practical application is still limited by inadequate ionic transport capability and poor moisture stability in the ambient environment. Herein, a simple yet effective Ta 5+ doping strategy is proposed to simultaneously improve the ionic conductivity and moisture stability of Li 2 ZrCl 6 (LZC). Specifically, the optimized Ta 5+ -doping SSEs, Li 2–x Zr 1–x Ta x Cl 6 (x = 0.3, denoted as LZT0.3C), exhibit an improved ionic conductivity of 1.31 mS cm −1 at room temperature (RT). Notably, LZT0.3C retains its structural integrity and high ionic conductivity even after exposure to 10% relative humidity. When implemented in ASSLBs with LiCoO 2 or single-crystalline LiNi 0.8 Mn 0.1 Co 0.1 O 2 cathodes, LZT0.3C delivers significantly improved long-term cycling stability. The combination of high ionic conductivity and enhanced moisture stability renders this halide SSE a scalable and cost-effective candidate for future energy storage systems.

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.

Abstract Catechol-functionalized UiO-66(Zr) holds considerable promise for targeted catalytic transformations owing to its distinctive electronic and structural properties. However, the direct synthesis of such frameworks has remained a persistent synthetic challenge. Herein, we report a rational, solvent-free, one-pot synthetic strategy enabling precise control over catechol functionalization in UiO-66(Zr) (UiO-66(Zr)-(OH)2) with well-defined hierarchical porosity. The optimized UiO-66(Zr)-0.25(OH)2 displays markedly improved catalytic performance in the esterification of levulinic acid (LA) with primary alcohols to yield alkyl levulinates. This superior activity arises synergistically from three key features: (i) increased Brønsted acidity imparted by the ortho-dihydroxyphenyl groups; (ii) a hierarchical pore architecture that enhances mass transport and substrate accessibility; and (iii) strong adsorptive affinity for both LA and alcohol substrates. Under standardized 12 h batch reactions with an alcohol-to-LA molar ratio of 20 and 50 mg of catalyst, UiO-66(Zr)-0.25(OH)2 achieves LA conversions of 98.9, 97.9, 95.6, and 94.3% with methanol, ethanol, 1-propanol, and 1-butanol, respectively, while maintaining >99.9% selectivity for the corresponding products of alkyl levulinates at optimally tuned reaction temperatures (60, 70, 80, and 100 °C). This work establishes a practical and environmentally sustainable synthetic strategy for the rational design of functionalized metal–organic frameworks, enabling high-efficiency, heterogeneous catalysis in targeted reactions.

Large-size Y 2 O 3 ceramics are important materials for optical windows, semiconductor etching substrates, and related technologies. However, the batch production of its transparent ceramics with high optical and mechanical properties remains a challenge, these include technical limitations of small-scale production of powder with high sinterability and complicated processing which involves pre-sintering in vacuum plus HIP with high cost and limited dimensions. In this paper, an industry-compatible way namely dry-pressing combined with vacuum sintering was adopted with commercial powders as starting material to achieving its transparent ceramics. Furthermore, four Zr precursors (ZrO 2 , zirconium acetate, nitrate, and basic carbonate) were doped as sintering additive for the regulation of Zr distribution from powder pretreatment to forming and sintering. Both agglomerates and pore clusters were suppressed, and a homogeneous microstructure was achieved when zirconium basic carbonate was used as the sintering additive. Hence, a large-size (100 × 100 × 2 mm) ceramic was fabricated, with both the in-line transmittance (80.2 % at 800 nm) and Vickers hardness (7.48 ± 0.08 GPa) optimized simultaneously. The study not only provides references and guidance towards the optical quality enhancement and microstructure control but also provides insights for the fabrication of large-size Y 2 O 3 transparent ceramics.

Surgical suture techniques are commonly used for hemostasis and wound closure, but they often fail to achieve optimal results, particularly in post-laceration hemostasis and healing. Furthermore, complications such as bacterial infections, oxidative stress, and inflammation often worsen the initial wound, leading to secondary damage. In this study, a novel tissue adhesive was developed by integrating a natural epigallocatechin-3-gallate (EGCG) and zirconium ion (Zr) chelate complex (EGCG-Zr) into a gelatin/starch hydrogel (GDSH). The resulting multifunctional tissue adhesive (EGCG-Zr@GDSH) exhibits excellent injectability, superior adhesion strength compared with commercial protein fiber-based tissue adhesives, and cytocompatibility. The hydrogel enables the sustained release of EGCG and Zr, providing effective antibacterial effects. In vivo histological analysis of an incision wound model revealed that EGCG-Zr@GDSH promotes angiogenesis and collagen deposition, scavenges reactive oxygen species, restores intracellular redox balance, and mitigates oxidative stress-induced cellular damage. Moreover, it regulates M1 macrophage polarization, thereby reducing the secretion of proinflammatory cytokines and alleviating inflammation. This hydrogel possesses antioxidant and immunomodulatory properties, indicating its application potential as a tissue adhesive and highlighting the importance of immune regulation in tissue repair and regeneration.

A fast fluorescent dual-emission platform for sensitive detection of sodium dehydroacetate (SDHA) in food is established utilizing bimetallic organic frameworks (Eu@Zr-MOFs). Eu@Zr-MOFs show two fluorescent emissions at 430 nm and 616 nm under single excitation wavelength of 290 nm. Two peaks separated by 180 nm help to eliminate environmental interference and improve the accuracy. In the presence of SDHA, fluorescent intensity at 430 nm and 616 nm shows fluorescent quenching within 1 min. Fluorescent lifetime results show that fluorescent quenching is a static quenching mode. Fluorescent quenching may be ascribed to the diketone structure of SDHA coordinated with Eu 3+ and internal filtering effect. The logarithm of fluorescent intensity (lg I 430 nm * I 616 nm ) has linear relationship with the concentration of SDHA from 0.1 µM to 200 µM with a limit of detection of 31.6 nM. More conveniently, it also achieves visual detection of SDHA through fluorescent color by portable UV lamp and smartphone “color capture” mode. The platform is applied to detect SDHA in fermented and baked food samples. Thus it is an efficient and sensitive fluorescent ratio method for SDHA detection with fast response, high selectivity and accuracy. Graphical

On-site rapid food safety testing is an important means of market supervision. A "Dual-response-Reverse" (one signal increases while the other decreases) type biomass carbon quantum dots(G-BCQDs)/Zr-MOFs ratiometric fluorescent paper-based sensor was designed for the visual detection of spermine concentration (SPM, a representative of biological amines).G-BCQD (emitting at 477 nm) and Zr-MOF (emitting at 537 nm) exhibit reverse fluorescence responses to spermine, namely quenching and enhancement, respectively, thus enabling fluorescence ratio detection. The smartphone was connected with the ratiometric fluorescent paper-based sensor to quantitatively detect the concentration of spermine. The results showed that there was a linear relationship between the concentration of spermine in the range of 0.1-220.0 μM and the R' value of RGB values, and the linear equation was R' = 0.3740CSPM + 141.75 (R2 = 0.9913). The detection limit of the method was 19.93 μM. Shrimp samples were selected to evaluate the practicability of the ratiometric fluorescent paper-based sensor for detecting spermine concentration. The results of the spiked recovery experiment showed that the recovery rate of the shrimp samples was in the range of 90.97-101.14%, and the relative standard deviation was less than 2.15%, indicating that the ratiometric fluorescent paper-based sensor had high accuracy and precision and was shown to be applicable for detecting SPM in spoiled samples and thus for monitoring spoilage.

Garnet-type solid-state electrolytes are celebrated for their exceptional stability against lithium metal, a property that is crucial for developing high safety all solid-state batteries. However, the practical adoption of this electrolyte is hindered by low ionic conductivity and poor interface contact. In this paper, we propose a novel strategy for fabricating the garnet-type high-entropy oxide solid-state electrolyte Li 6 La 3 Zr 0.5 Ti 0.5 Cr 0.5 Sn 0.5 O 12 (LLZTCSO) by low-cost partial substitution of Zr with Ti, Cr, Sn in the LLZO. By the lattice distortion effect generated by Zr substitution, LLZTCSO achieves rapid lithium ion migration, high air stability, and excellent mechanical properties. As a result, Li/Ag@LLZTCSO/Li symmetric cell shows lower interfacial impedance (100.5 Ω cm 2 ) and higher critical current density (1.428 mA cm −2 ) than LLZO. The LiFePO 4 (LFP)/Ag@LLZTCSO/Li full cell also exhibits good rate capability (145.06 mA h g −1 at 0.5C) and cycling performance (capacity degradation of 12.13% after 100 cycles at 0.1C). This study outlines a novel approach for the synthesis of high-performance garnet-type electrolytes for all-solid-state lithium metal batteries, providing important references for the design of garnet-type solid-state electrolytes in the future.

Fuels with extremely low sulfur content are highly desirable as a result of the growing environmental concerns. In this work, a simple and novel method to connect a ZrIV open site with polyoxometalates (POM) was introduced, which was used as an effective heterogeneous catalyst for oxidative desulfurization of fuel oil. ZrPTAX-BTC composites were synthesized conveniently and rapidly at room temperature and atmospheric pressure using pyromellitic acid (BTC) as a linker. The products were characterized by XRD, TGA, FT-IR, NMR, SEM, and N2 adsorption–desorption, which verified the successful preparation of ZrPTAX-BTC composite. ZrPTAX-BTC catalyst has high content of active components, and has excellent catalytic activity in oxidative desulfurization reaction. It achieves rapid and complete desulfurization under mild reaction conditions (T = 50 °C, O/S = 4, t = 30 min, DBT removal rate reaches 100%). Further studies show that the synergistic catalysis of a ZrIV open site and PTA molecule is the reason for its high catalytic activity, in which the ZrIV open site promotes the decomposition of H2O2 into O2·, PTA molecules combine with O2· to form peroxytungstate (W(O2)n), and the close distance between the ZrIV open site and PTA in ZrPTAX-BTC allows H2O2 to be efficiently utilized. In addition, ZrPTAX-BTC can be easily recovered and reused for at least five times, and only a slight decrease in catalytic activity has occurred. Therefore, ZrPTAX-BTC has high catalytic activity, high stability, and good reusability, which is a potential catalyst that can realize the application of fuel ultradeep desulfurization.

Zirconium tanning agent, which is mainly composed of low-toxic tetravalent zirconium (Zr 4+ ) salts, has been considered the most promising eco-friendly tanning agent for leather manufacturing, due to its comparable tanning performance with trivalent chrome. However, in the initial penetration stage of the zirconium tanning process, macromolecular multinuclear complexes are commonly formed because of the rapid coordination between hydrated Zr 4+ , which can easily cross-link with active groups of neighboring collagen fibers and thus block subsequently even penetration of zirconium tanning agents, resulting in surface over-tanning and ununiform tanning effects. Herein, to address the aforementioned issues of conventional zirconium tanning, inert-surface modification of collagen fibers was proposed by using PEGylated epoxy copolymers (PEGMA-co-GMA, defined as PPG) to pretreat bated hide, based on the covalent reactions and hydrogen-bond interactions of PPG with amino and carboxyl groups on collagen fibers, respectively. After modification, the surface reactivity of skin collagen was significantly reduced, which was able to delay the cross-linking interactions with zirconium tanning agents and thus promote uniform penetration. Simultaneously, the extra hydroxyls produced from the ring-open reactions of epoxy groups could also mitigate the excessive coordinated complexation of hydrated Zr 4+ , leading to efficient penetration of zirconium tanning agents. Compared with conventional zirconium tanning, research results showed that this inert-surface modification strategy could comprehensively improve the overall leather performance with both efficient and uniform tanning effects. Moreover, the resultant leather qualities, including thermal stability, physical and mechanical properties, and organoleptic properties , are very comparable with chrome-tanned leather. In addition, attributing to the reaction between collagen amino and PPG, the use of sodium chloride was avoided, resulting in a cleaner salt-free pickling process. Altogether, this inert-surface modification strategy represents a significant step forward for effective and cleaner tanning technology , which will accelerate the wide application of Zr(IV) in place of traditional chrome tanning agents.
