Small Quinone-based Organic Electrodes have received extensive attention. However, the rapid dissolution of small quinone electrode into electrolyte impede their practical applications. For example, Anthraquinone (AQ) and Phenanthrenequinone (PQ) molecules have been rarely reported for aqueous batteries due to the inferior electrochemical performance. Herein, a high-concentration hybrid electrolyte containing 1m Zn(OTF) 2 and 15m KOTF salts is introduced for small quinone electrode and investigate the redox behavior of PQ and AQ electrode is investigated in Zn 2+ /K + hybrid electrolyte. These findings reveal that AQ with carbonyl groups at para-position selectively stores proton rather than K + , while PQ with carbonyl group at ortho-position simultaneously stores proton and K + without selectivity. Moreover, the Zn(OTF) 2 salt serves as both proton buffer and binder to improve the cycle stability. Consequently, when PQ is paired with Zn metal anode for Zn || PQ batteries, the addition of potassium salt can improve the energy density of the Zn batteries. Moreover, when PQ is paired with Prussian blue cathode to assemble aqueous K-ion batteries, the addition of zinc salt in the electrolyte can improve the cycle stability via binding discharged PQ molecules with divalent-ions. This research provides an electrolyte engineering strategy to address the challenges facing PQ electrode for aqueous batteries.

The hyperglycemic microenvironment of diabetic chronic wounds is a major driver of severe bacterial infections, excessive inflammatory responses, and impaired angiogenesis, all of which delay wound healing. To address these challenges, we prepared a glucose oxidase (GOx)–loaded zeolitic imidazolate framework-8 (GOx@ZIF-8). Furthermore, a multifunctional hydrogel (AACZ) was fabricated by incorporating 5-methylfurfural– and L-arginine–grafted alginate and maleimide–grafted chondroitin sulfate with GOx@ZIF-8 through the Diels–Alder reaction. Results showed that immobilized GOx remained active for a longer time than of free GOx. At the wound site, GOx catalyzed the conversion of excess glucose to gluconic acid and hydrogen peroxide (H 2 O 2 ). The reduced pH in the local region induced Zn 2+ release from zeolitic imidazolate framework-8, simultaneously, H 2 O 2 mediated the generation of nitric oxide (NO) from L-arginine. The synergy between Zn 2+ and NO endowed AACZ with excellent antibacterial properties. The biocompatible hydrogel promoted cell proliferation and migration, regulated local blood glucose levels, inhibited bacterial activity, alleviated inflammation and promoted angiogenesis and collagen deposition at the diabetic wound site. These findings suggest that AACZ holds promise as a responsive dressing material in healing for complex wounds.

Hydrogel electrolytes with antifreezing performance and excellent mechanical properties have become a research hotspot, but the general preparation process requires time and energy consumption, limiting the scope of applications. In this work, a simple, universal, and fast gelation based on a sodium lignin sulfonate macromolecule–zinc ion (LS-Zn2+) self-catalytic system is developed. The catechol group of LS can coordinate with Zn2+ to form complexes and accelerate the establishment of reversible oxidation–reduction, which can promote the rapid polymerization of vinyl monomers by generating various free radicals (OH• and 1O2). The gelation process does not require any additional energy and can be completed within 5 min by controlling the mass fraction of LS and the concentration of Zn2+ or acids. The mechanical strength of the preferred hydrogel electrolyte can reach a tensile stress of 0.14 MPa under 1750% strain. The hydrogel electrolyte possesses an excellent conductivity of 3.67 mS cm–1 at extreme temperatures as low as −40 °C. The hydrogel electrolyte sensor can detect various parts of the human body in a wide temperature range with stable output resistance signals. This work provides a LS-Zn2+ self-catalytic method for the rapid preparation of multifunctional hydrogels.

Background In recent years, environmental pollution has been increasing due to the excessive emission of toxic ions, which has caused serious harm to human health and ecological environment. There are various methods for detecting Cu 2+ , S 2− and Zn 2+ , but the traditional ion detection methods have obvious disadvantages, such as poor selectivity and long detection time. Therefore, it is still crucial to develop simple, efficient and rapid detection methods. Results A fluorescent probe based on benzothiazole, ( E )- N '-(3-(benzo[ d ]thiazol-2-yl)-2-hydroxy-5-methylbenzylidene)-3,4,5-tris(benzyloxy)benzohydrazide ( BT ), was designed and synthesized. It was characterized using ESI-MS, 1 H NMR, and 13 C NMR. BT can be used as a chemosensor to detect Cu 2+ , S 2− and Zn 2+ in CH 3 CN/H 2 O (7:3, v/v, pH = 7.4, HEPES buffer: 0.1 M), with detection limits of 0.301 μM, 0.017 μM, and 0.535 μM, respectively. At an excitation wavelength of 320 nm, BT exhibits an “on-off-on” response to Cu 2+ /S 2− and enhanced fluorescence response to Zn 2+ , with a change in fluorescence color from orange to green. The coordination ratio of ions to the probe was determined to be 1:1 through Job's plot and hydrogen spectral titration. The recognition mechanism was discussed in conjunction with theoretical calculations. Furthermore, the probe has been successfully used in test strips and medical swabs colorimetry, as well as live cell imaging. Significance The probe BT lays the foundation for the design and synthesis of multifunctional fluorescent probes. As a portable detection method, probe BT was used to detect Cu 2+ , S 2− and Zn 2+ on strips. Furthermore, the probe was applied to biological cells to detect target ions with low cytotoxicity and excellent cell permeability. This indicating that it can be used as a potential candidate for tracking Cu 2+ and S 2− in clinical diagnostics and biological systems.

In this work, a water-soluble guanidyl-imidazoline ( G ) was synthesized and used as a fluorescent probe to detect Zn 2+ in an aqueous environment without any mutually soluble organic solvent. G demonstrates excellent selectivity for Zn 2+ and strong anti-interference ability against other metal ions. It has an ultra-low detection limit of 25 nM for Zn 2+ ions, surpassing previously reported achievements. Job’s plot method, FTIR and XAFS revealed the binding mode of the G -Zn complex that the N atom in the G coordinates with Zn 2+ in a ratio of 2:1. Furthermore, this probe was successfully utilized for quantitative detection of Zn 2+ ions in tap water and synthetic water, and also applied to imaging Zn 2+ ions in living cells.

ASr(YDy) 2 O 4 phosphors co-doped with La 3+ and Zn 2+ ions, prepared using a solid-state reaction method. The incorporation of La 3+ and Zn 2+ ions influences the crystal structure, surface morphology, and luminescent characteristics. X-ray diffraction analysis confirms a phase transition from SrY 2 O 4 to SrLa 2 O 4 with La 3+ substitution, while scanning electron microscopy reveals particle growth and morphological changes. The introduction of Zn 2+ enhances crystallinity and increases luminescence intensity at characteristic Dy 3+ emission peaks. Thermal quenching analysis demonstrates stable luminescence at elevated temperatures, indicating excellent thermal stability. The combined effects of La 3+ and Zn 2+ co-doping improve optical properties and material durability, making these phosphors promising for advanced photonic and lighting applications requiring high luminescent efficiency and thermal stability.

Mobile divalent zinc, Zn(II), is an essential cofactor involved in mammalian biological processes. To understand the intrinsic action mechanism of mobile zinc, the development of a Zn2+-selective fluorescent probe that can detect mobile zinc via biological imaging is of great significance. We present here a novel Zn2+-selective fluorescent sensor based on poly(2-oxazoline) (POx) cylindrical molecular brushes with good water solubility and biocompatibility. The POx molecular brushes were end-capped by a Zn2+-responsive functionality, which can give efficient blue emission upon coordination with zinc ions. Fluorescence investigation indicates that the POx molecular brushes exhibit superior selectivity toward Zn2+ in comparison with most competitive heavy and transition metal ions. Due to the ease of cellular uptake that results from their unique molecular contour, POx molecular brushes are capable of detecting intracellular Zn2+ ions as demonstrated by living cell fluorescence studies.

This work presents a molecular-level design strategy for organic-inorganic composite gel electrolytes to address the performance degradation of aqueous zinc-ion hybrid supercapacitors (ZIHSs) under low-temperature conditions. A three-dimensional interpenetrating polymer network was constructed to synergistically enhance mechanical strength and ion transport kinetics. By integrating a water-ethylene glycol (EG) binary solvent system with ZnSO 4 electrolyte, the coordination hierarchy of Zn 2+ was modulated as Zn 2+ -SO 4 2+ > Zn 2+ -EG > Zn 2+ -H 2 O, where the preferential Zn 2+ -EG interaction facilitates rapid solvent exchange and accelerates Zn 2+ migration in EG-containing electrolytes. This molecular engineering strategy effectively resolves the ion transport limitations of conventional hydrogel electrolytes at subzero temperatures: the optimized electrolyte membrane exhibits excellent wide temperature range adaptability, and its ionic conductivity changes from 19.25 mS·cm −1 at room temperature to 11.11 mS·cm −1 at −30 °C. Furthermore, the dynamic Zn 2+ coordination network formed in situ enables uniform charge distribution, achieving ultrastable Zn plating/stripping in symmetric cells (1390 h cycling). The quasi-solid-state ZIHS device demonstrates an ultra-high specific capacity of 267.3 F·g −1 at 2 V operating voltage, and its energy density (165.22 Wh·kg −1 ). This work establishes a novel paradigm for designing wide-temperature-range zinc-based energy storage systems through molecular-scale electrolyte engineering.

Although some sensors for Cu 2+ and Zn 2+ had been reported, the sensor with long-wavelength emission in aqueous media for in-situ detecting Cu 2+ and Zn 2+ was always expected. Herein, a biphenylacrylonitrile Schiff-base ( OPBS ) with large aromatic conjugated system was designed and synthesized in yield of 82%. OPBS possessed excellent long-wavelength fluorescence at 550–750 nm in aqueous media, which selectively response to sense Cu 2+ with quenched fluorescence and Zn 2+ with chromotropic fluorescence from red to yellow. The detection of Cu 2+ and Zn 2+ were realized without mutual interference in their coexistence system by means of the assistance of ATP. The detection limits were 2.3 × 10 −7 M for Cu 2+ and 1.8 × 10 −6 M for Zn 2+ , respectively. The sensing mechanism was elucidated by binding MS spectra, fluorescence Job’s plot and 1 H NMR spectra. Moreover, OPBS exhibited good bioimaging performance and the in-situ sensing abilities for Cu 2+ and Zn 2+ in living cells, suggesting the application potential for detecting Cu 2+ and Zn 2+ in both vitro assay and vivo environment.

Aqueous rechargeable zinc-ion batteries (ARZIBs) are considered as attractive candidates for the next generation of high-safety and low-cost energy storage in large-scale power grids. However, challenges such as the dendrites and the corrosion on the zinc (Zn) surface result in short battery life and low reversibility of Zn plating/stripping. In this work, a method of preconditioning of a zinc anode in hybrid electrolytes (based on poly(ethylene glycol)-200 and H2O) to form a solid electrolyte interphase (SEI) that prevents anode corrosion and dendrites is proposed. Though surface composition analysis and density functional theory calculation, this SEI has dense organic and inorganic components due to the induction of organic molecules and anions and has rapid kinetic and high-throughput properties for the transport of zinc ions. As a result, the SEI-modified Zn anode can maintain a low-voltage hysteresis stable cycle for more than 1600 h in aqueous electrolyte. The anode also exhibits impressive reversibility with a high Coulomobic efficiency of 99.23% over 1300 cycles. Furthermore, the ARZIB encapsulated by this anode and Mn-doped V6O13 cathode enables an outstanding electrochemical stability (181.8 mAh g–1 after 800 cycles at room temperature, 102.2 mAh g–1 after 1000 cycles at −15 °C). This work provides an intriguing idea for the stability maintenance of the anode for ARZIBs or other metal-ion batteries.

Infected bone defects remain one of the greatest challenges in orthopedics, as bacterial contamination and insufficient vascularization severely compromise regeneration. Here, we report the development of a multifunctional 3D-bioprinted scaffold composed of zinc ion (Zn 2+ ) functionalized silk fibroin methacryloyl (SFMA), histidine methacryloyl (HisMA), and nano-hydroxyapatite (nHAP), further loaded with endothelial progenitor cells (EPCs) to promote simultaneous antibacterial, angiogenic, and osteogenic responses. The photocrosslinkable SFMA/HisMA bio-ink reinforced with nHAP provided mechanical stability, controlled swelling and degradation, while Zn 2+ coordination endowed strong antibacterial activity against E. coli and S. aureus . EPCs adhered and proliferated on the scaffolds, markedly enhancing osteogenic differentiation, angiogenesis while suppressing oxidative stress, as evidenced by increased expression of OCN, RUNX2, COL1, OPN, VEGF and inhibited lipid and mitochondrial ROS levels. Proteomic profiling further revealed that EPC-loaded scaffolds orchestrate osteoblast protein expression, promoting immunoregulation and extracellular matrix (ECM) reconstruction to accelerate tissue regeneration. In a murine femoral infected defect model, EPC-loaded scaffolds suppressed pro-inflammatory cytokines, stimulated angiogenesis, and supported robust new bone formation, leading to accelerated defect repair confirmed by μCT and histological analyses. Together, these findings demonstrate that the EPC-loaded Zn 2+ functionalized SFMA/HisMA/nHAP scaffold integrates antibacterial defence with vascular and osteogenic stimulation, offering a promising translational strategy for the treatment of complex infected bone defects.

Al 2 O 3 : Er 3+ /Yb 3+ transparent ceramics codoped with Zn 2+ ions with intense upconversion and near infrared emission were prepared by conventional solid-state reaction and vacuum and hot isostatic pressing sintering. The effects of Zn 2+ incorporation to the structure, transparent, upconversion and NIR luminescence were discussed in detail. The as prepared Al 2 O 3 ceramics exhibited a total transmittance of ~ 75% in infrared regions (800–3300 nm) and ~ 50% in visible regions (500–800 nm). Under the excitation of a 980 nm laser diode , the as prepared Al 2 O 3 ceramics displayed two tense upconversion emission peaks of a green one centered at 550 nm and a red one centered at 660 nm and a tense near infrared emission peak centered at 1.532 µm, characteristic of Er 3+ emission. Compared with Er 3+ /Yb 3+ doped only, Zn 2+ codoped Al 2 O 3 :Er 3+ /Yb 3+ transparent ceramics showed higher upconversion and near infrared emission of ~ 11 times and ~ 4 times, respectively. The enhancement mechanism due to incorporation of Zn 2+ ions was also discussed in detail.
