Aqueous zinc-iodine (Zn||I 2 ) batteries, recognized for their cost-effectiveness, safety, and environmental sustainability, are emerging as the next-generation energy storage technologies. However, capacity degradation arising from the detrimental parasitic reactions at both the negative electrode and positive electrode interfaces presents substantial challenges for the practical implementations of Zn||I 2 batteries. Herein, we develop zwitterion-mediated interface chemistry to modulate the interface reactions using the zwitterion of 1-butylsulfonate-3-methylimidazolium (BM) as an electrolyte additive. At the negative electrode, the alignment of electric field-oriented BM molecules creates a dynamic dual-asymmetry interface, facilitating homogeneous Zn deposition and protecting the Zn metal electrode from the water and corrosive polyiodides. At the positive electrode, the reconfigured solvation configuration of iodide ions, involved by BM molecules, deactivates the interface reaction associated with the I 2 dissolution and polyiodide formation. Consequently, Zn||I 2 batteries with BM additive demonstrate enhanced rate capability (135.5 mAh g −1 at 20.0 A g −1 ) and extended durability (capacity retention of 91.9% after 50,000 cycles at 10.0 A g −1 ). The zwitterion-mediated interface chemistry effectively tackles the insurmountable challenges of aqueous Zn||I 2 batteries, facilitating their reliable and practical implementation.

Reactive oxygen species (ROS) play a dual role in cellular processes, serving as essential signaling molecules at moderate levels but inducing oxidative stress and cell death in excess. Coronavirus infections significantly elevate intracellular ROS, disrupting cellular antioxidant defenses and promoting viral replication. Given the challenges posed by coronaviruses, including their high pathogenicity and cross-species transmission, new antiviral strategies are urgently needed. This study reports a newly designed zinc-based metal–organic framework (Zn-MOF) material, NJAU1, featuring a 2-fold interpenetrating helical porous structure synthesized through aqueous self-assembly technology. NJAU1 was characterized using advanced analytical techniques and demonstrated broad-spectrum antiviral activity against various coronaviruses, including PEDV, TGEV, and PDCoV. The underlying antiviral mechanisms of NJAU1 involve direct viral particle inactivation, inhibition of viral internalization and replication, ROS scavenging, anti-inflammatory and antioxidant activities, as well as Zn2+-mediated modulation of ferroptosis and apoptosis. This work highlights NJAU1 as a promising multifunctional antiviral material that offers a novel approach to the prevention and treatment of coronavirus infections.

The solvent free reaction of Zn(OAc)2 with an imidazole ligand resulted in a 1-dimensional (1D) chain structure with the formula [Zn(Im)(HIm)2(OAc)] (Im = imidazolate, HIm = imidazole, OAc = carboxylate) (1). The results by kinetic experiments suggest that (1) likely evolves from an unidentified metastable phase. This new 1D chain precursor (1) is a quaternary system comprising Zn, Im, OAc and HIm. We have used this 1D compound as a single precursor to prepare 3-dimensional (3D) Zn(Im)2 frameworks. Specifically, two Zn(Im)2 frameworks with known zni and coi topologies were prepared via thermal-mediated transformation when heated in an open atmosphere and in a closed vessel, respectively. In an open atmosphere, the kinetic experiments confirmed the rapid phase transformation from (1) to zni without formation of an intermediate phase. In contrast, in the formation process of coi in a closed vessel, phase transformation from (1) to zni and immediately from zni to coi was observed. Thus, in a closed vessel, the released molecules, HOAc and HIm, were occluded in the framework, which may together exert a cooperative structure-directing effect on the formation of the coi framework. Thus, a single precursor approach was established for the synthesis of ZIFs. The present work represents the first example of transforming a 1D coordination polymer into 3D ZIF framework structures.

Coke oven gas (COG) is a hydrogen-rich byproduct whose efficient utilization requires deep removal of organic sulfur compounds such as thiophene . While Cu-based sorbents exhibit excellent desulfurization performance, the influence of precursor structural characteristics on their activity remains poorly understood. In this study, the relationship between precursor assembly and desulfurization performance of unpromoted Cu/ZnO/Al 2 O 3 sorbents was systematically elucidated. Three synthesis routes were explored to tailor precursor structures, revealing that aurichalcite-derived precursors enable superior Cu dispersion, stronger Cu-Zn interaction, and enhanced reducibility of active sites. The optimized sorbent prepared via urea hydrolysis achieved an exceptional breakthrough sulfur capacity of 29.91 mg/g—nearly twice that of hydrotalcite-derived counterparts—without the use of additional promoters. Mechanistic analysis further demonstrates that the precursor structure governs the formation of highly reducible Cu species and promotes thiophene activation through improved hydrogenation pathways. These findings provide new insights into the design of high-performance Cu-based sorbents.

Monovalent cation permselective membranes (MCPMs) manifest remarkable effectiveness and potential in lithium extraction whereas facing the challenge to achieve high permselectivity and high Li + permeability simultaneously. In this work, Zn-TCPP, a kind of two-dimensional nanosheet with abundant negative charges, was successfully synthesized via surfactant-assisted method and introduced into surface cross-linked SPES membrane to fabricate MCPMs. The physicochemical properties, electrochemical properties and Li + /Mg 2+ separation performance of resulted MCPMs were systematically estimated. As ions passing through the membrane, dense PVA/GA crosslinked layer separated Li + and Mg 2+ by pore-size sieving effect. Afterwards, uniformly distributed Zn-TCPP nanosheets with rich negative charges and physically adsorbed water molecules elevated the charge density and water content in the membrane and thus expedited Li + transporting. Therefore, high Li + /Mg 2+ permselectivity ( P Mg 2 + Li + = 8.99) and Li + permeation flux ( J Li + = 9.12 × 10 −9 mol cm −2 ∙s −1 ) were obtained. Furthermore, membrane surface resistance was reduced from 108.99 Ω cm 2 to 24.12 Ω∙cm 2 . This study points out the feasibility of the new method for accelerating monovalent ion transport and alleviating the restriction between ion permeation and permselectivity in selective ion exchange membranes.

Zn alloy engineering has emerged as a promising anodic strategy for aqueous Zn-ion batteries (AZIBs), effectively suppressing side reactions and dendritic growth. However, the impact of multiphase alloy compositions on zinc deposition and overall battery stability remains insufficiently understood. In this study, a versatile deep eutectic solvent (DES) was employed as both the electrolyte and the reaction medium for multiphase alloy formation. Hierarchically porous Cu-Zn multiphase alloys were fabricated on a three-dimensional (3D) Cu foam substrate (Cu-Zn/CF) via electrochemical deposition, with precise control over alloy composition achieved by adjusting deposition parameters. The synergistic interactions among Cu-Zn alloying elements significantly enhance the hydrogen evolution overpotential, reduce corrosion current, and effectively suppress Zn dendrite formation during repeated cycling. Furthermore, the combination of Cu-Zn alloys with the 3D Cu foam architecture facilitates highly reversible zinc plating and stripping processes. Consequently, the Cu-Zn/CF anode demonstrates exceptional cycling stability, maintaining performance for over 4000 h at 0.5 mA·cm −2 (0.5 mAh·cm −2 ). Notably, the anode retains excellent cycling stability with minimal polarization and an average Coulombic efficiency of 99% even under rigorous operating conditions. This work not only clarifies the functional roles of alloying components but also presents a novel strategy for the development of stable, dendrite-free zinc metal anodes.

Zn and its alloys are increasingly under consideration for biodegradable bone fracture fixation implants owing to their attractive biodegradability and mechanical properties . However, their clinical application is a challenge for osteoporotic bone fracture healing , due to their uneven degradation mode, burst release of zinc ions , and insufficient osteo-promotion and osteo-resorption regulating properties. In this study, a type of Zn 2+ coordinated zoledronic acid (ZA) and 1-hydroxyethylidene-1,1-diphosphonic acid (HEDP) metal-organic hybrid nanostick was synthesized, which was further mixed into zinc phosphate (ZnP) solution to mediate the deposition and growth of ZnP to form a well-integrated micro-patterned metal-organic/inorganic hybrid coating on Zn. The coating protected noticeably the Zn substrate from corrosion, in particular reducing its localized occurrence as well as suppressing its Zn 2+ release. Moreover, the modified Zn was osteo-compatible and osteo-promotive and, more important, performed osteogenesis in vitro and in vivo of well-balanced pro-osteoblast and anti-osteoclast responses. Such favorable functionalities are related to the nature of its bioactive components, especially the bio-functional ZA and the Zn ions it contains, as well as its unique micro- and nano-scale structure. This strategy provides not only a new avenue for surface modification of biodegradable metals but also sheds light on advanced biomaterials for osteoporotic fracture and other applications. Statement of significance Developing appropriate biodegradable metallic materials is of clinical relevance for osteoporosis fracture healing, whereas current strategies are short of good balance between the bone formation and resorption. Here, we designed a micropatterned metal-organic nanostick mediated zinc phosphate hybrid coating modified Zn biodegradable metal to fulfill such a balanced osteogenicity. The in vitro assays verified the coated Zn demonstrated outstanding pro-osteoblasts and anti-osteoclasts properties and the coated intramedullary nail promoted fracture healing well in an osteoporotic femur fracture rat model. Our strategy may offer not only a new avenue for surface modification of biodegradable metals but also shed light on better understanding of new advanced biomaterials for orthopedic application among others.

Configurational entropy composites of In-doped Zn(O,S)/Zn-doped In(OH) 3-x S x has been synthesized with a one-step hydrothermal method and carefully characterized with XRD , XPS , SEM, TEM, DRS , PL , EIS , TPC , CV , and MS analyses. The composites were prepared with different sulfur amounts to obtain the optimum performance of visible-light photocatalytic HER . The primary phases of ZnS and In(OH) 3 were formed after the hydrothermal process. However, the results indicated In and O were doped into ZnS lattice and induced lower bandgap values (~2.71–2.84 eV) which are active in visible-light illumination. Simultaneously, the excess Zn and S were also doped to In(OH) 3 with lower bandgap values (~3.38–4.63 eV). The variation of bandgap values is due to the hybridization of In 5s5p to Zn 4s4p and O 2p to S 3p orbitals. As a result, In-doped Zn(O,S) and Zn-doped In(OH) 3-x S x will be a visible-light active material for photoreaction and a favorable phase for electron transfer , respectively. Furthermore, it is also related to a possible antisite-defect formation with I n Z n + to help the electron trapping and enhance the photocarrier separation, leading to an efficient photocatalytic activity . ZI-S1 with additional 5-mmol thioacetamide was found as the catalyst with the highest HER performance which achieved 730 μmol/g·h under visible-light illumination. A plausible photocatalytic HER mechanism is discussed and proposed in this work.

Organic–inorganic metal halides with tunable and state room-temperature phosphorescence (RTP) properties in advanced luminescent materials have received broad interest. Herein, 2-(methylamino)pyridine (MAP), 2-[(methylamino)methyl]pyridine (MAMP), and 2-(2-methylaminoethyl)pyridine (MAEP) were designed and hybridized with Zn2+ and Cl−/Br−, yielding 11 hybrid materials. MAP-based compounds, with a narrow bandgap (3.57 eV), exhibit limited RTP due to inefficient intersystem crossing (ISC) and unstable triplet excitons. In contrast, MAMP (4.49 eV)- and MAEP (4.50 eV)-based compounds achieve enhanced RTP through bandgap alignment with Zn halides, enabling efficient energy transfer, ISC, and triplet exciton stabilization via strong hydrogen bonding and π-conjugation effects. Covalent bonding in MAMP and MAEP compounds provides greater rigidity and exciton stability than hydrogen-bonded systems, resulting in prolonged afterglow durations, while Br-bonding enhances ISC and spin–orbit coupling (SOC), and the weak interactions increase non-radiative decay, further reducing afterglow duration. Density functional theory calculations confirm the enhanced SOC in MAMP and MAEP compounds, further improving RTP efficiency. This work demonstrates the precise control of RTP properties, highlighting the potential in advanced anti-counterfeiting and emerging photonics applications.

All-inorganic cesium lead halide perovskites (CsPbX 3 , X = Cl, I, Br) have attracted great attention for developing high-performance photovoltaics due to their superb thermal stability. However, the short electron-hole diffusion lengths ( L D s) in CsPbI 2 Br perovskite are the primary limiting factor for further improvement of the power conversion efficiencies (PCEs) of the CsPbI 2 Br solar cells. Herein, a simple yet effective method is reported to prolong the L D s in CsPbI 2 Br via codoping of Zn 2+ and acetate (Ac − ) ions (i.e., using Zn(Ac) 2 as dopant). It is demonstrated that Zn 2+ partially replaces Pb 2+ to form a more stable black phase, and Ac − coordinates with Pb 2+ to passivate the defects at the perovskite grain boundaries which reduces electron-hole recombination within the perovskite. As a result, the L D s of Zn(Ac) 2 doped CsPbI 2 Br are greater than 1 μm, which is the first report on all-inorganic perovskites. The champion PCE of the CsPbI 2 Br solar cells is drastically increased from 12.31% to 14.93% upon doping with Zn(Ac) 2 , stemming mainly from the increased open-circuit voltage and fill factor. Furthermore, the non-encapsulated devices with Zn(Ac) 2 doped CsPbI 2 Br show less than 10% efficiency loss after storage in dry air for 30 days.

Anion‒water interactions in aqueous electrolytes can lower the freezing point for antifreezing applications, yet cation‒water interactions have usually been ignored. Here, we propose that the cation effect of Al 3+ can simultaneously exert a deshielding effect on both H and O in water, which significantly weakens the water hydrogen bond and lowers the freezing point to −117 o C at a low salt concentration of 2.8 m. Additionally, dual-cation effects further optimize the ion diffusion kinetics and facilitate the formation of an Al‒Zn alloy layer for Zn electrode safeguarding. As demonstrated in batteries, the designed electrolyte enables the symmetrical Zn||Zn coin cell for 10,340 h of Zn plating/stripping and Zn||polyaniline pouch cell with a capacity retention of 100% after 500 cycles at 100 mA g -1 and −70 o C. Even at −80 o C, the Zn||polyaniline cell delivers a discharge capacity of 115.5 mA h g -1 . The cation effect offers an effective strategy for regulating the water structure of low-temperature aqueous devices.

Vanadium nitride (VN) with a wide working window has been identified as a promising electrode material candidate for batteries due to the high specific capacitance and the excellent electrical conductivity. Here, we have successfully prepared VCN nanobelts, which display mesoporous structure with high specific surface area (54.4 m2g−1) and the total pore volume was 0.266 cm3g−1. Furthermore, the prepared flexible Zn-ion battery (FZIB) with VCN-5 not only exhibited high specific capacitance (81 μAh cm−2), excellent rate capability, and long cyclic durability (77% after 1000 cycles at 0.6 mA cm−2) but also had the characteristics of flexibility. This FZIB is important to reduce the difficulty in thermal management and can be used in a series of applications, including wearable electric devices.
