Zn 2+ ions sensing is vital for human health and environment, and developing low-cost, water-soluble, efficient probes is still highly demanded. Herein, we report a water-soluble imidazole-based fluorescent polymer as a ratiometric probe for Zn 2+ ions sensing. By a facile radical co -polymerization, the water-soluble fluorescent polymer of PVIV-0.5BTAM was obtained carrying imidazole and imidazolium moieties together with a small amount of diphenylbenzothiadiazole (BTAM) units. Upon excitation, PVIV-0.5BTAM gave rise to dual emission bands centered at 430 nm and 540 nm, corresponding to imidazole/imidazolium and BTAM, respectively. The addition of Zn 2+ ions can coordinate with imidazole rings via multi-valent mode and act as a crosslinker, leading to the intra- and/or inter-macromolecular aggregation. Accordingly, the yellow emission of BTAM was enhanced proportionally, while the blue emission of imidazole/imidazolium kept stable and served as internal standard. The linear working curve can be established by plotting the value of I 540 /I 430 as a function of Zn 2+ ions concentration. Thus, a low-cost, water-soluble, ratiometric fluorescent polymer probe was provided as a promising candidate for Zn 2+ ions sensing.

Purpose Gadolinium-based contrast agents (GBCAs), which are indispensable for magnetic resonance imaging (MRI), carry a severe risk of nephrogenic systemic fibrosis (NSF) in patients with chronic kidney disease (CKD), particularly in those with advanced renal impairment. This critical safety concern necessitates the development of biocompatible alternatives that do not compromise diagnostic efficacy.Materials and Methods Inulin-based nanoparticles (Inulin@Gd/Zn NPs) were synthesized by chelating inulin with gadolinium and zinc ions, aimed at being used as contrast agents that can replace conventional GBCAs. The morphology, size, and zeta potential of the nanoparticles were determined. The anti-fibrotic ability of Inulin@Gadolinium/zinc nanoparticles (Inulin@Gd/Zn NPs) was evaluated in vitro and in vivo, as well as their MRI imaging ability and metabolic performance in normal and fibrotic kidneys. A unilateral ureteral obstruction (UUO) model was created in mice and was used to evaluate the in vivo anti-fibrotic efficacy.Results The ultra-small Inulin@Gd/Zn NPs (<10 nm) exhibited high stability and T1 relaxivity. Compared to Gadolinium diethylenetriaminepentaacetic acid (Gd-DTPA), Inulin@Gd/Zn NPs demonstrated precise kidney targeting, excellent T1-weighted MRI capabilities, and rapid renal clearance. In vitro studies showed that Inulin@Gd/Zn NPs had very low cytotoxicity for HK-2 cells up to 100 µM. Further, the NPs were able to reduce reactive oxygen species generation in hydrogen peroxide–stimulated HK-2 cells. Negligible levels of hemolysis and organ toxicity were confirmed in vivo. Further, in the UUO model, administration of Inulin@Gd/Zn NPs was found to significantly inhibit fibrosis. Both in vitro and in vivo experiments demonstrated that Inulin@Gd/Zn alleviated GBCA-induced early tubulointerstitial fibrosis by inhibiting the transforming growth factor-β1 (TGF-β1) signaling pathway.Conclusion Inulin@Gd/Zn NPs represent a promising strategy for clinical application of GBCAs. It addresses the diagnostic and therapeutic challenges in patients with CKD, offering a paradigm shift in the safe application of GBCAs in high-risk populations, indicating the need for further clinical trials to enable clinical applications.

Rechargeable aqueous zinc-air batteries (ZABs) are promising candidates for next-generation energy storage due to their high safety, substantial energy density, and low cost. However, their practical adoption is impeded by inherent issues of conventional zinc anodes, such as dendrite formation, volume expansion, and low zinc utilization during repeated electroplating and stripping. To address these challenges, this study fabricates stable Sn Cu current collectors as anode substrates from Sn-plated copper bases with varying architectures. Electrochemical characterization confirms that the Zn@Sn-Cu electrode inherits the high ionic conductivity of the copper substrate while effectively suppressing hydrogen evolution and reducing the local corrosion current density. Post-cycling scanning electron microscopy (SEM) further reveals that the introduced Sn layer mitigates zinc dendrite growth during deposition/stripping cycles, facilitating the formation of a highly dense and uniform zinc layer on the Sn Cu substrate. Consequently, ZABs assembled with Zn@Sn-2DCu and Zn@Sn-3DCu anodes deliver high specific energy densities of 783 and 800 mAh·g −1 , respectively. Notably, the Zn@Sn-3DCu battery achieves an extended cycle life of over 1800 cycles at a current density of 1 mA·cm −2 .

Advancing photothermal materials requires synergy between light collection and efficient heat transport. However, nanoscale photothermal fillers, while strengthening absorption, are constrained by limited dispersibility and high interfacial resistance. By contrast, micrometer-scale metal fillers aid conduction yet lie outside the plasmonic regime, and their smooth surfaces promote specular reflection, which limits light capture. Consequently, leveraging their latent complementarity is crucial. Here, a multiscale structure and interface strategy is introduced, in which electrodeposition and alloying build a structured Cu–Zn interface with bead-chain-like nanostructures along the flake edges, thereby forming a metallic backbone that lowers interfacial thermal resistance and simultaneously promotes light capture and heat transfer. Specifically, at 8 vol% loading the composite attains through plane and in plane thermal conductivities of 1.06 and 2.73 W m −1 K −1 . Moreover, it shows broadband absorption (200–800 nm) and exhibits rapid heating and steady state output under both broadband solar and UV irradiation, under 365 nm illumination the film warms to 91.3°C within 30 s, indicating a favorable steady state photothermal heating efficiency under the defined conditions. This strategy offers a scalable route for interface engineering of microscale metal fillers and thus couples’ light absorption, heat transport, and energy use in solar-responsive and renewable energy conversion systems.

Aqueous zinc-ion batteries (AZIBs) face challenges such as dendrite growth and byproduct accumulation in practical applications. Herein, an innovative strategy of alkali corrosion is utilized to tune crystal facets of a Zn electrode, selectively weakening the active (101) plane and highlighting the (002) plane. Furthermore, a protective interface composed of coordination polymers and inorganic zinc compounds has been synchronously fabricated, exhibiting remarkable mechanical robustness. The engineered multifunctional protective layer (MPL) also possesses abundant zincophilic sites that can significantly promote the uniform Zn ion distribution on the interface and demonstrates remarkable efficacy in improving corrosion resistance, inhibiting dendrite formation, promoting uniform zinc deposition, and significantly enhancing the cycling performance of AZIBs. Therefore, the symmetric cell with Zn@MPL exhibits superior cycling stability over 5000 h at 0.5 mA cm–2 and excellent rate performance at 10 mA cm–2. When cycled for 2300 cycles, a full cell using Zn@MPL and MnO2 can still deliver a capacity retention rate of 51.4% at 5 A g–1, which is 24 times longer than the cycling lifespan of the bare Zn-based cell decaying to the same capacity. The successful preparation and application of a unique MPL provide some new insights for exploring safe and stable AZIBs.

A high adsorption capacity and excellent recyclability are the most critical factors for large-scale application of adsorbents. In this work, a regenerable Zn-UiO-66 was synthesized by doping Zn into UiO-66. The resulting adsorbent exhibited a high adsorption performance for TCH with a qmax of 178.9 mg g−1 at 30 °C and maintained stable adsorption performance across a broad pH range (3–11). The adsorption kinetics and thermodynamics of TCH, together with the zeta potential of the adsorbent under different pH conditions, further confirm the underlying adsorption mechanism, which is proceeded via monolayer chemisorption, primarily governed by π–π conjugation, π–cation interactions, coordination interactions and hydrogen bonding. The adsorbent also performed well in real water matrices. Importantly, Zn-UiO-66 exhibits good water stability and excellent recyclability, with only a slight decrease in adsorption capacity after five cycles using simple water rinsing, underscoring its strong potential for efficient antibiotic removal.

Transition metal borides (TMBs) are considered promising electrocatalysts for alkaline hydrogen evolution reaction (HER), but their potential has not been effectively utilized due to their inherent activity and challenges in fine morphology regulation during chemical/electrochemical deposition processes. Here, we prepared Zn incorporated NiB catalyst (NZB) on nickel foam by a simple one-step chemical deposition combined with local dealloying method. It was revealed that Zn incorporation plays a multifunctional role in the activity and stability of NZB catalysts towards alkaline HER. The partial leaching of Zn regulated the microstructure of the NZB, while residual Zn optimized the electronic structure of the NZB catalyst, improving the interaction between the catalyst and HER intermediates, thereby simultaneously increasing the number of active sites and intrinsic activity. Furthermore, we found the introduction of Zn accelerated the completion of surface reconstruction and improved the crystallinity of catalysts, resulting in enhanced chemical and mechanical stability. These findings provide key insights into maximizing the potential of transition metal-based catalysts for HER.

Constructing a stable solid electrolyte interphase (SEI) for isolating the anode from electrolyte is extensively employed to inhibit side reactions and achieve uniform Zn deposition. However, since the SEI inherently allows Zn 2+ transfer, it also inevitably permits H + migration across the interface, thereby triggering hydrogen evolution reactions (HER) and corrosion. Therefore, this work in-situ constructs a hierarchical multifunctional SbZn and ZnF 2 interface layer (SZZF) on the Zn anode surface to address these challenges. Specifically, the outer ZnF 2 -rich layer with hydrophobic properties acts as a physical barrier, facilitating Zn 2+ desolvation and homogenizing Zn 2+ flux. The inner SbZn alloy-rich layer provides abundant nucleation sites and weakens Zn–H + bonding through d-p hybridization, effectively suppressing HER activity and enabling uniform Zn 2+ deposition. Furthermore, the SZZF interface effectively suppresses corrosion-related side reactions induced by the iodine shuttle. Consequently, the SZZF@Zn symmetric cells exhibit exceptional cycling durability of 7000 h. Even under 85% depth of discharge (DOD) at 10 mA cm −2 and 30 mAh cm −2 , the symmetric cell achieves a long cycling life for over 550 h. Remarkably, the SZZF@Zn||I 2 full cell maintains a capacity of 97% after 50,000 cycles, and the SZZF@Zn||I 2 pouch battery with 1.65 Ah stably cycles over 115 cycles. The results present a feasible and efficient interface optimization strategy for realizing highly reversible aqueous zinc iodine batteries.

Ideal electrolytes for low-temperature-resistant aqueous zinc-ion batteries should promote rapid ion desolvation while stabilizing interfacial reactions. Existing research generally introduces additive molecules for optimizing local coordination environment to inhibit H 2 O crystallization; the strong hydrogen bond (HB) effect between co-solvents still exists, and uncoordinated polar groups act as acceptors/donors to induce uneven group coordination and the formation of new strong HB networks. Herein, we propose an electrolyte design strategy with a coordination-induced mechanism to address the long-standing challenges of slow low-temperature kinetics and irregular dendrites in aqueous zinc-ion batteries. By introducing low-carbon polyols to optimize the global solvation structure, low-temperature ice crystallization through intramolecular strain is mitigated, promoting the interaction between non-coordinating solvents to shift from strong HB (O-H:O*, 30 kJ/mol) to weak HB (C-H:O*, 5 kJ/mol), which enables dynamic salt-water-organic cosolvent ternary interaction, promoting rapid Zn 2+ reaction kinetics and stabilizing interfacial reactions. Both experimental and theoretical analyses confirm the effectiveness of the present strategy, which enables low-carbon-polyol-based electrolyte to exhibit a high capacity of 65.13 mAh/g at −25 °C (1 A/g) and a capacity retention of ~95% after 600 cycles.

en This link goes to a English section zh This link goes to a Chinese section Aqueous Zn-ion batteries (AZIBs) are expected to become one of the most promising candidates for large-scale energy storage, but are impeded by uncontrollable dendrite growth and parasitic reactions. In this study, we propose a simple mechanical shot-peening (SP) approach for restructuring commercial Zn foils into highly exposed (002)-textured crystal planes while inducing grain refinement. The SP process effectively eliminates the surface passivation layer and structural defects, enhances the mechanical properties and corrosion resistance of the electrode surface, and provides abundant active sites for Zn nucleation. This promotes homogeneous and smooth deposition of zinc and ensures a uniformly distributed electric field, thereby suppressing dendrite growth and reducing side reactions. Consequently, the SP-treated Zn (SP-Zn) anode enables a symmetric cell that exhibits impressive reversibility and stable cycling for over 5000 h at 2 mA cm −2 , and an SP-Zn||MnVO full cell delivers 81% capacity retention after 2000 cycles at 5 A g −1 . This simple and cost-effective SP strategy offers a practical approach to fabricating high-performance Zn metal anodes, providing a scalable strategy for practical AZIB applications. 摘要 en This link goes to a English section zh This link goes to a Chinese section 水系锌离子电池(AZIBs)有望成为大规模储能领域最具前景的候选方案之一,但其发展受限于不可控的枝晶生长和寄生反应。本研究提出了一种简单的机械喷丸(SP)处理方法,对商用锌箔进行重构,以诱导高度暴露的(002)织构晶面,同时实现了晶粒细化。SP工艺有效去除了表面钝化层和结构缺陷,改善了电极的力学和耐腐蚀性能,并为锌成核提供了丰富的活性位点。可有效这促进锌的均匀沉积,确保了电场的均匀分布,从而抑制了枝晶生长并减少副反应。结果表明,经SP处理的锌(SP-Zn)负极组装的对称电池在电流密度为2 mA cm − 2 的测试条件下表现出优异的可逆性和稳定性,循环时间超过了5000小时,SP-Zn||MnVO全电池在5 A g −1 的测试条件下循环2000次后容量保持率达81%。该简便且低成本的SP策略为制备高性能锌金属负极提供了一种实用途径,为AZIBs的实际应用提供了一种可规模化的解决方案。

The valence electron configuration largely determines the performance of functional materials, in which different electron spin and orbital occupancy would induce diverse phenomena. Herein, the study of 3d electronic configuration dominant gas sensing selectivity is presented. Utilizing ultrafast Joule heating, transition metal spinels XCr 2 O 4 (X = Co, Ni, Zn) have been synthesized and consistently exhibit sensing selectivity toward xylene gas. The e g empty orbitals of Cr 3+ 3 d 3 (t 2g 3 e g 0 ) tend to overlap with the π orbitals of xylene molecules, achieving stable xylene adsorption and electron transfer and thus presenting remarkable xylene gas sensing selectivity. The valence electron configurations of 3 d 7 , 3 d 8 and 3 d 10 for Co 2+ , Ni 2+ and Zn 2+ result in a progressively lower response to xylene gas. This valence electron configuration perspective is experimentally supported by gas sensing selectivity of XFe 2 O 4 (X = Co, Ni, Zn) toward acetone molecules, in which the electronic orbital configuration of Cr 3+ 3 d 3 of B sites is replaced by Fe 3+ 3 d 5 . Theoretically, density functional theory (DFT) calculations based on adsorption energy and charge density difference confirm the strong adsorption of xylene at Cr 3+ sites and efficient electron transfer from xylene to Cr sites.

Trace Ag (Ag/Cu = 0.001) significantly enhanced Cu-Zn catalyzed CO 2 hydrogenation. • STY MeOH of Cu-Zn-Ag 0.001 was 467.8 g·kg −1 ·h −1 , 1.82 times higher than Cu-Zn. • Ag promotes oxygen vacancy formation around active sites at the Cu-ZnO interface. • Methanol synthesis follows the formate pathway with Ag lowering energy barriers. The methanol synthesis from catalytic CO 2 conversion has emerged as an attractive strategy for carbon valorization and sustainable energy generation. However, the catalytic efficiency of conventional Cu-Zn-based catalysts remains far from satisfactory. Herein, a Cu-Zn-Ag catalyst, synthesized via a facile co-precipitation method, exhibited a significantly improved methanol production activity compared with Cu-Zn catalysts. Notably, a trace amount of Ag doping (the Ag/Cu molar ratio was 0.001) could significantly elevate the methanol generation, with its space-time yield increasing from 258 ± 17 to 468 ± 23 g MeOH ·kg cat −1 ·h −1 , an increase of 1.82 times, while further increasing Ag doping would lead to reduced activity. Structural characterizations confirmed the Ag presence, being doped in the Cu lattice, and Ag doping was significantly beneficial to oxygen vacancy formation, which was deemed the active sites for methanol formation. The detailed reaction pathway (formate pathway) for methanol synthesis was also investigated based on density functional theory (DFT) calculations, where Ag doping lowered the energy barriers. This work elucidates the mechanism of Ag doping in Cu-Zn catalysts and provides key insights into the reaction mechanism of CO 2 hydrogenation to methanol, highlighting its potential for sustainable methanol synthesis.
