In this study, transition metal halides and phenolic resin were utilized to synthesize (TiHfVNb)C medium-entropy precursors by multi-metal organic frameworks (MOFs) method. The (TiHfVNb)C submicron particles were obtained by carbothermal reduction at a relatively low temperature (1500 °C) and subsequently consolidated into medium-entropy carbide ceramics via spark plasma sintering at 1950 °C. Effects of molar ratios of transition metal halides and phenolic resin, pyrolysis temperatures and holding time on the properties of MOFs-derived (TiHfVNb)C submicron particles was systematically investigated. Comprehensive characterization was performed on the as-synthesized submicron particles using FTIR, TGA, XRD, SEM, EDS and TEM, revealing that the as-synthesized submicron particles exhibited an elliptical morphology with fine particles size (~150 nm) and uniform particle size and elemental distribution. The MOFs-derived (TiHfVNb)C ceramic by SPS achieved a high density of 99.6% and displayed homogeneous microstructure. Remarkably, the SPS-sintered (TiHfVNb)C ceramics demonstrated competitive mechanical properties, with Vickers hardness and fracture toughness values reaching 21.7 GPa and 4.4 MPa·m¹ / ², respectively.

Ice accretion severely compromises wind turbine efficiency. Herein, a fluorine-free photothermal superhydrophobic coating (FPSC) was fabricated via scalable spraying of MWCNTs-OH and TiN. The coating exhibited a water contact angle of 159.0 ± 2.5° and a low roll-off angle of 3.4 ± 0.3°, ensuring excellent water repellency and self-cleaning durability. Benefiting from the elevated nucleation energy barrier induced by its hierarchical micro/nanostructure, the FPSC significantly prolonged the droplet freezing process, achieving freezing times of 3907 ± 20 s, 1357 ± 15 s, 959 ± 13 s, and 731 ± 10 s at −5, −10, −15, and −20 °C, respectively. Furthermore, owing to strong solar absorption, the coating maintained stable performance over 40 photothermal cycles under 1 sun irradiation even after mud-contaminant removal, and melted frost and ice within 108 s and 255 s, respectively, under 1.5 sun irradiation. On a blade model, it achieved >99% initial anti-icing efficiency. Notably, a theoretical assessment accounting for environmental performance degradation indicates that the FPSC can recover approximately 487.3 h of annual operational downtime in Northeast China, corresponding to a recovery of 11.1% of annual energy production loss. Consequently, it is projected to contribute an additional 122.2 TWh generation gain by 2025. This scalable FPSC provides a robust, economically viable anti-icing solution.

The precise separation of dyes and inorganic salts in industrial dyeing wastewater is crucial for achieving efficient dye removal while recovering salt resources. Conventional nanofiltration membranes suffer from limitations due to their limited pore size tunability range. In this study, a novel polyamide (PA)-based loose nanofiltration (LNF) membrane was fabricated via interfacial polymerization (IP), with cyclen as the aqueous monomer, isophthaloyl chloride (IPC) as the organic monomer, and ionic liquid (IL) as the aqueous cosolvent. Characterizations and MD simulations demonstrate that IL decouples bulk and interfacial diffusion, enabling membrane pore size tuning. The IL-95 v/v% membrane featured a loose PA selective layer characterized by thin thickness, low cross-linking degree, and large pore sizes. It exhibited a high permeance of 26.9 LMH·bar −1 and excellent AB172 dye rejection (99.8%), while maintaining low rejection (<10.0%) for various inorganic salts, outperforming most currently reported LNF membranes. Notably, the IL can be efficiently recovered via salt-induced phase separation (SIPS) from the post-IP waste aqueous solution, realizing the cyclic reuse of IL and reducing the environmental impact and cost of the process. This work offers new avenues for the application of high-performance LNF membranes to separate organics and salts in organic pollutant-laden wastewater.

The synthesis of novel film-like photocatalysts is an effective strategy for reducing Cr(VI). Herein, a Z-scheme ZnIn 2 S 4 –CdS heterojunction photocatalyst was fabricated on a self-assembled graphene-based substrate via hydrothermal and solvothermal methods. By controlling the ethanol:water ratio during solvothermal synthesis, differently sized CdS nanoparticles were grown on the ZnIn 2 S 4 nanosheets surface for regulating the photocatalytic activity of ZnIn 2 S 4 –CdS heterojunction. The three-dimensional layered structure of the graphene film provided abundant active sites for material loading and its excellent conductivity rapidly transferred photogenerated electrons. Compared to the ZnIn 2 S 4 –CdS heterojunction samples with other controlled structure, graphene-based film-like photocatalyst bring advantage in enrich photocatalysts for bursting out better activity. Under visible light irradiation, the synthesized RZC-40 sample exhibited a photocatalytic efficiency of 91.02% in photoreducing 20 mg L −1 Cr(VI) within 50 min, highlighting the feasibility and promising practical application prospects of synergistic film-like photocatalysts and laying a theoretical foundation for the further development of photocatalysts with improved activity.

It is significant to fabricate mechanically tunable and highly fire-safety ionogels for meeting the requirements in different application fields. In this work, multifunctional flame-retardant ionogels (MFIGs) with widely tunable mechanical properties were fabricated via in situ UV-initiated polymerization of acrylamide and acrylic acid dispersed in flame-retardant phosphorous-containing ionic liquid. The mechanical properties of MFIGs could be regulated by adjusting the phase structure via changing the content of PIL and monomers. MFIGs were robust and rigid (tensile strength of 9.9 MPa and modulus of 2.1 MPa) when they showed “sea-island” structure, and were flexible and stretchable (modulus of 51.1 kPa and elongation at break of 587%) when a co-continuous phase formed. MFIGs exhibited outstanding flame retardancy with a limiting oxygen index of 54.5%. Meanwhile, MFIGs showed good electrical resistance response and thermoelectric conversion properties, which had multiple fire-warning performance to further enhance fire safety. Our work provides new insights for the fabrication of multifunctional and smart fire protection ionogels.

Regulating phase composition and constructing integrated heterostructures have proven to be an effective strategy for enhancing bifunctional oxygen electrocatalysis and improving the performance of zinc–air batteries. Herein, a series of Co, Er, and N co–doped carbon–based electrocatalysts with nanocubic framework structures composed of Co, Er 2 O 3 , and Co 3 O 4 phases were derived from zeolitic imidazolate framework-67 (ZIF-67) by tuning the Er content (0%, 1%, 3%, 4%, 5%, 6%, etc.). Experimental and physicochemical characterizations reveal that when the Er doping amount reaches 4% (Er(4)–Co/NC), the catalyst exhibits a higher density of defect structures and a larger pore size compared to other electrocatalysts. Meanwhile, the formation of a Er 2 O 3 –Co Mott–Schottky heterojunction composed of an appropriate ratio of Co and Er 2 O 3 phases significantly optimizes the electronic structure of Er(4)–Co/NC. In situ Raman spectroscopy further demonstrates that after 4% Er incorporation, the Er(4)–Co/NC catalyst shows lower overpotentials for the adsorption of the four OER intermediates (*OH − , *OOH − , *O − , and *O 2 − ). Consequently, Er(4)–Co/NC delivers a half-wave potential of 0.91 V for the oxygen reduction reaction (ORR) and an overpotential of 0.31 V at 10 mA cm −2 for the oxygen evolution reaction (OER), indicating its effective bifunctional ORR/OER performance. The corresponding rechargeable zinc–air battery (ZAB) achieves an ultralong cycling lifetime exceeding 1000 h (3000 cycles) and also displays excellent performance in flexible zinc–air battery configurations. This work is expected to broaden the application scope of rare–earth–element doping and ZIF–derived materials in oxygen electrocatalysis and metal–air battery devices.

Hydrogels, as a class of functional material, have been used in various fields such as flexible sensors, actuators, and energy devices. Nevertheless, their practical application is often hampered by the poor mechanical properties and susceptibility to dehydration. In this work, using hygroscopic salt lithium nitrate trihydrate (LNH) as the phase-change material, PVA/PAM/LNH salt hydrogels were prepared in a mixture of water and glycerol. The mechanical performance of the hydrogels reached to 326 kPa from 31.5 kPa after the crystallization triggered by crystal seed at room temperature. Since phase transition triggered by crystal seed primarily occurs at the hydrogel surface, the surface contains a higher concentration of LNH crystals, forming an inhomogeneous structure. The composite hydrogel exhibits reversible adhesion, higher water retention ability enabling it to maintain long-term flexibility at low relative humidity. Moreover, the abundant Li + ions present in the gel enable high conductivity, humidity sensitivity and contribute to the piezoelectric and piezoresistive capabilities.

Interference is a significant source of laboratory errors that can cause erroneous measurement results. In clinical practice, all the measured results should exclude the influence of interference. In this study, the ion exchange high-performance liquid chromatography of hemoglobin A1c (HbA1c) was evaluated via three brands of HbA1c analyzers, and 12 endogenous and 24 exogenous substances were added to hemoglobin solutions with different HbA1c levels to simulate the corresponding clinical samples. After the potential interfering substances were screened via interference screening testing, the interference concentration thresholds of each potential interfering substance were determined on the basis of dose–response experiment. When these substances exceed the interference concentration thresholds, elevated HbA1c values are caused by endogenous cholic acid and low pH, whereas exogenous ethanol increases HbA1c measurements in samples with low values. However, HbA1c measurements decreased in samples with high values. Although there are some differences in the thresholds of interferent concentrations between different brands of analyzers, the differences are not significant. On the basis of the detailed interference concentration thresholds and interference substances, this evidence can be provided to clinical laboratory experts and help them interpret and determine the testing results of clinical laboratories.

Efficient bifunctional electrocatalysts are crucial for the advancement of rechargeable zinc-air batteries (ZABs). In this article, we successfully synthesized a high-performance catalyst R-CoOOH@FeOOH through the oxygen evolution reaction (OER). Additionally, in situ Raman characterization results indicate that CoFe@NC-w undergo electrochemical reconstruction during the OER, leading to the formation of CoOOH and FeOOH species. This dynamic structural evolution is responsible for the enhanced OER activity of the catalyst. This transformation endowed the catalyst with exceptional OER activity. In addition, the catalyst exhibited exceptional performance in the oxygen reduction reaction, which shows a half-wave potential of 0.86 V vs. (RHE) reversible hydrogen electrode. When integrated into a ZAB, the catalyst delivers a low charging potential of 2.3 V at a high current density of 50 mA cm −2 , accompanied by an excellent long-term durability of 600 h. These findings offer viable strategies for the development of high-performance catalysts for ZAB.

Ensuring stable soft tissue sealing at the transgingival zone of titanium (Ti) abutments is critical for long-term implant success, yet conventional Ti abutment surfaces lack intrinsic antibacterial functionality. Here, a multifunctional antibacterial coating was developed by immobilizing pH-responsive nanorods (NRs) composed of tanshinone IIA (TA), lactoferrin (LF), and sodium alginate (SA) onto a polydopamine-modified (PDA) Ti surface. The resulting Ti&PDA@NRs coating achieved a high TA loading capacity through synergistic electrostatic adsorption and covalent crosslinking. The coating exhibited pH-modulated release behavior, characterized by accelerated TA release under acidic conditions and sustained release at physiological pH. Antibacterial evaluations using representative oral bacterial species demonstrated effective inhibition of bacterial adhesion and biofilm formation via surface-mediated contact killing, while released TA further suppressed free bacteria, confirming a dual-mode antibacterial mechanism. Mechanistic studies indicated that antibacterial activity was associated with bacterial membrane disruption accompanied by elevated intracellular reactive oxygen species (ROS) generation. Cytocompatibility assessments using human gingival fibroblasts and NIH/3T3 cells under both normal and inflammatory conditions confirmed low cytotoxicity. Moreover, the coating maintained good stability and sustained TA retention under simulated oral conditions. Collectively, this work presents a clinically relevant antibacterial surface strategy for mitigating implant-associated bacterial challenges in the transgingival region.

Anode-free solid-state sodium batteries (AFSSBs) emerge as a highly promising next-generation energy storage technology, offering exceptional energy density and significant cost advantages. However, their practical deployment remains challenging, primarily due to an insufficient understanding of Na dendrite formation and the absence of effective strategies to address the rigid multiphases interface, mitigate volume expansion, and reactivate inactive sodium. In this study, we systematically investigate the morphologies evolution of sodium at the interface between the Cu current collector and Na 5 SmSi 4 O 12 (NSSO) solid electrolyte. Building upon these findings, we design an iodinated polymeric elastic artificial interphase layer ( I -PIL) with dual functionality. This layer not only ensures conformal interfacial contact through photoinitiated polymerization and atomic bonding, but also reactivates dead sodium via spontaneous reaction with the incorporated I 3 − species. Consequently, Na|Cu half-cells achieve remarkable cycling stability, remaining a Coulombic efficiency of 99.7% for over 1000 h at 1.5 mA cm −2 . When paired with Na 3 V 2 (PO 4 ) 3 cathode, the AFSSBs retain 85.8% capacity after 2000 cycles at 1.0 mA cm −2 and preserve 92.8% capacity over three months under high mass loading of 28 mg cm −2 . This work provides fundamental insights into sodium deposition and establishes a versatile and scalable interfacial design strategy for high-performance, durable anode-free solid-state batteries.

The existing TUF membranes often face challenges such as declining permeation flux and insufficient separation selectivity. This study proposes to improve the above problems by the synergistic effect of Mg–Al layered double hydroxide (LDH) and tannic acid (TA) etched metal–organic frameworks (MOFs): (1) TUF membranes with adjustable interlayer distances and multi-level mass transfer channels were constructed by doping LDH two-dimensional (2D) nanosheets; (2) TAZIF-L (Co) etched by TA was introduced. TA inhibited the swelling of LDH nanosheets through coordination and enhanced the interface binding between ZIF-L (Co) and the substrate, thereby suppressing its shedding. The results showed that TA can etch ZIF-L (Co), and the membrane prepared after etching has better selectivity and stability of dye/salt separation. Taking MTAZIF-0.02 as an example, the pure water flux was 88.23 L m −2 h −1 , which was 1.91 times that of MLDH. The removal rate of congo red (CR) solution was 92.56%. The NaCl rejection in methyl blue (MB)/NaCl solution was 10.88% and in CR/NaCl solution was 10.57%. This study provides an experimental basis for the construction of highly selective ultrafiltration membrane for the treatment of high concentration dye/salt wastewater.
