A novel water-soluble polyurethane copolymer (i.e., LnBPU-[Zn(DOPA)2]) was synthesized through a route mainly using a prepolymer (i.e., BPU), lignin, dopamine and Zn2+ as the raw materials by cross-linking copolymerization. The optimal reaction conditions are as
follows: m(Lignin):m(BPU) is 1:4, time is 4 h and temperature is 70 °C. The prepared LnBPU-[Zn(DOPA)2] was turned out to improve the strength, resistance to water, oil and Escherichia coli of fibre when it was evenly coated on the paper
with a dose of 15 g/m2. SEM & EDS, FT-IR, GPC confirmed that the crosslinking copolymerization was enhanced by dopamine and Zn2+, which can give the polyurethane copolymer better strength and water and oil resistance. This study provided an efficient and green approach
for preparing lignin-based polyurethane, and contributes to the application of paper in more fields such as food or medical packaging.

Cu 2+ and Zn 2+ , two ubiquitous metals in water environments, can widely trigger algae blooms at favourable environmental conditions. This paper elucidates the roles of Cu 2+ and Zn 2+ in the proliferation of Microcystis aeruginosa ( M. aeruginosa ) and synthesis of Microcystins (MCs). Findings indicate significant influences of increasing Cu 2+ and Zn 2+ concentrations on cell proliferation at limited available phosphorus concentrations of less than 0.1 mg/L. By contrast, Cu 2+ and Zn 2+ notably affected MCs production at all the inoculated phosphorus concentrations. The critical concentrations of 1 μg/L and 5 μg/L for Cu 2+ and Zn 2+ , respectively, are determined to trigger rapid cell proliferation and MCs production. Furthermore, the impacts of Cu 2+ and Zn 2+ on nitrogen absorption and, subsequently, on amino acids (AAs) formation in cells, is likely key in MCs synthesis. The two AAs Alanine (Ala) and glutamic acid (Glu) demonstrate the most notable variations with the concentrations of Cu 2+ & Zn 2+ .

The development of aqueous battery with dual mechanisms is now arousing more and more interest. The dual mechanisms of Zn 2+ (de)intercalation and I − /I 2 redox bring unexpected effects. Herein, differing from previous studies using ZnI 2 additive, this work designs an aqueous BiI 3 -Zn battery with self-supplied I − . Ex situ tests reveal the conversion of BiI 3 into Bi (discharge) and BiOI (charge) at the 1st cycle and the dissolved I − in electrolyte. The active I − species enhances the specific capacity and discharge medium voltage of electrode as well as improves the generation of Zn dendrite and by-product. Furthermore, the porous hard carbon is introduced to enhance the electronic/ionic conductivity and adsorb iodine species, proven by experimental and theoretical studies. Accordingly, the well-designed BiI 3 -Zn battery delivers a high reversible capacity of 182 mA h g −1 at 0.2 A g −1 , an excellent rate capability with 88 mA h g −1 at 10 A g −1 , and an impressive cyclability with 63% capacity retention over 20 K cycles at 10 A g −1 . An excellent electrochemical performance is obtained even at a high mass loading of 6 mg cm −2 . Moreover, a flexible quasi-solid-state BiI 3 -Zn battery exhibits satisfactory battery performances. This work provides a new idea for designing high-performance aqueous battery with dual mechanisms.

The prolonged healing period and increased rates of amputation and mortality are significant challenges for diabetic patients’ wound care in clinical practice. Therefore, there is an urgent need to develop timely and efficient wound management strategies to monitor the local glucose while promoting rapid wound healing. In this study, a multifunctional hydrogel (PF127@Zn/C-G) was constructed by coloading the monitoring and therapeutic carbon dot (CD)-based agents (Zn/C) and glucose oxidase (GOx). For applications, the ″off–on″ characteristic in fluorescence (FL) signal of the Zn/C assemblies enabled the real-time monitoring of the local glucose levels in diabetic wounds. Moreover, the synergistic effect of Zn2+ and CDs was developed to promote wound healing. In vitro and in vivo results showed that the PF127@Zn/C-G hydrogel exhibited a good linear relationship between FL intensity and glucose concentration, and the FL signal intensity in the wound environment in vivo correlated well with the blood glucose, suggesting its function for timely reflection of the blood glucose content. In addition, the PF127@Zn/C-G hydrogel could accurately fit the wound contour to form a protective film, while effectively promoting cell proliferation and migration, and scavenging the accumulated ROS at the local wound, exhibiting an excellent angiogenic capacity and collagen deposition for significantly accelerating the wound healing during tissue remodeling. Therefore, the multifunctional hydrogel lPF127@Zn/C-G provides an effective and feasible candidate for improving the diabetic wound management.

Composite phase change materials (CPCMs) face challenges such as leakage and low thermal conductivity, which considerably limit their widespread application. To address these issues, an innovative CPCM composed of polyethylene glycol (PEG), Zn 2+ metal–organic framework (MOF@Zn 2+ ), and expanded graphite (EG) was proposed and prepared using in situ synthesis and physical mixing. This simple synthesis method eliminates the need for harsh preparation conditions, such as high temperatures, high pressures, or specific catalysts. MOF@Zn 2+ was designed by optimizing the citric acid monohydrate (CAM): zinc acetate dihydrate (ZAD) molar ratio at 3:2, with NaOH providing the necessary alkaline chelating environment. The synergistic effects of MOF@Zn 2+ and EG enable the double optimization of thermal conductivity and antileakage performance. The thermal conductivity of PEG/CAM/ZAD/EG (PCZE4) was reached to 4.32 W/mK that contained citric acid monohydrate (CAM) and zinc acetate dihydrate (ZAD) with 3:2, which was 12 times higher than pure PEG (0.33 W/mK). After heating at 90 °C for 4 h, the PCZE4 retained 98.38 % of its mass. The results reveals that PEG-based CPCM achieves an optimal balance between high thermal conductivity, thermal stability, and latent heat. The heat storage capacity is reflected in the enthalpy of melting (114.24 J/g) and crystallization (102.88 J/g). The proposed CPCM design offers promising insights into passive thermal management systems and energy storage applications.

Fresh fruits and vegetables, rich in vitamins and essential nutrients, play an essential role in supporting human health. However, the perishability during transit and storage causes rapid degradation; consuming spoiled items poses significant health risks. Extending the shelf life of fresh produce has therefore become a key challenge for the food industry. In this study, a multifunctional composite coating was developed by integrating chlorogenic acid–zinc ion (CGA-Zn 2+ ) metal–phenolic network (MPN) particles into a polymer matrix composed of sesbania gum (SG) and biguanide-modified chitosan (Bi-Ch). Cherry tomatoes were used as the model fruit to investigate the coating's preservation effect. The CGA-Zn 2+ MPN particles provided strong antioxidant properties, which worked in combination with the antibacterial activity of Bi-Ch, enabling the coating to offer both protective and bioactive functions. The addition of MPN particles significantly improved the antioxidant capacity of the coating, increasing it from 64.83 % to 97.31 %. Moreover, the coating showed enhanced antibacterial performance. Preservation results confirmed that this composite coating effectively extended the shelf life of cherry tomatoes to 9 days at least while maintaining their quality. Cytocompatibility assays validated its safety for food applications. As a biocompatible, readily removable intervention, this approach offers considerable promise for enhancing fresh fruit stability throughout supply chains—mitigating waste and bolstering food safety.

Fiber-shaped supercapacitors (FSCs) serve as optimal energy storage components in wearable platforms. However, traditional fiber materials suffer from poor interfacial cross-linking, disordered microstructures, insufficient active sites, and low electrical conductivity. To overcome these challenges, this research develops Zn-MoO₃/Ti₃C₂Tₓ hybrid fibers via wet-spinning technology employing glacial acetic acid as a coagulation bath, with MoO₃ quantum dots intercalated into Ti₃C₂Tₓ interlayers and Ti₃C₂Tₓ nanosheets cross-linked by Zn 2+ . The resulting hybrid fibers feature expanded interlayer spacing, a large ion-accessible surface area, abundant porous channels, exceptional electrical conductivity, and excellent mechanical properties, delivering an exceptional volumetric capacitance of 2078.2 F cm −3 at 2 A cm −3 with 75.0 % capacitance retention at 20 A cm −3 . Furthermore, the constructed FSCs achieve a substantial energy density of 55.6 mWh cm −3 at a power density of 400 mW cm −3 , with 94.7 % capacitance retention after 5000 cycles, and successfully power an electronic timer, demonstrating their potential for wearable applications.

Prussian Blue analogs (PBAs) are a suitable aqueous zinc-ion batteries (AZIBs) cathode material, but they face issues related to low specific capacity and cycling lifespan due to insufficient active sites and poor ion de-intercalation structural stability. In this study, Mn-Prussian Blue Analog (Mn-PBA) is fabricated using a simple co-precipitation method and the morphology of Mn-PBA is further optimized through artificially manipulating concentration gradients strategy, effectively enhancing the structural stability of Zn 2+ de-intercalation. Furthermore, the introduction of Mn established dual Zn 2+ active centers in Mn-PBA (Mn-O and Fe(CN) 6 ] 4− /[Fe(CN) 6 ] 3− ), leading to an increased specific capacity. As a proof of concept for AZIBs, the optimized Mn-PBA-3 cathode exhibits a high reversible specific capacity of 143.5 mAh/g and maintains a capacity retention of 88.5 % after 250 cycles at 1 A/g, surpassing commercial MnO 2 (30.5 mAh/g after 100 cycles). Mn-PBA-3 also delivers a high capacity of 79.0 mA h g −1 after 2000 cycles of 10 A/g. The mechanism of the Zn 2+ double redox reaction of Mn-PBA-3 has been revealed in detail by in situ Raman and a series of ex situ techniques. Under a high operating voltage window of 0–1.9 V, Zn//Mn-PBA-3 demonstrates a capacity of 99.3 mAh/g after 800 cycles (5 A/g) by assembling zinc ion button battery. This work has reference significance for structurally modulated PBAs used in high performance AZIBs.

Aqueous zinc ion batteries (AZIBs) have emerged as promising candidates for next-generation large-scale energy storage systems, owing to their safety features and substantial theoretical specific capacity. Nevertheless, their application remains hindered by uncontrollable dendrite growth and side reactions on zinc anodes. In this work, an innovative chitosan/gelatin (CS/Gel) composite polymer gel interfacial layer was engineered through physical cross-linking and facile coating methods. Theoretical calculations revealed that the abundant functional groups in CS/Gel exhibited strong interactions with Zn2+, which promoted rapid desolvation of [Zn(H2O)6]2+ and captured H2O molecules. Additionally, multi-physics field simulations exhibited that the crosslinked networks of Zn@CS/Gel could homogenize the current density distribution and zinc ion concentration distribution on the anode surface, facilitating dense and homogeneous zinc deposition. Importantly, the Zn@CS/Gel symmetric cell provided a stable cycle life of 4400 h at 0.5 mA cm−2. The Zn@CS/Gel‖MnO2 cell could exhibit stable cycle life up to 1000 cycles at 1 A g−1. The rational design of the composite protective layer provides effective guidance for designing robust zinc anodes in AZIBs.

Zinc ion (Zn 2+ ) detection is critically important in both environmental and biological systems. Although Zn 2+ plays an important role in metabolic processes, excessive intake can lead to toxic effects, highlighting the need for simple and effective detection methods for Zn 2+ . In this study, palladium nanoparticle-decorated reduced graphene oxide (Pd@rGO) nanocomposite was drop-cast onto a glassy carbon electrode (GCE) to develop a facile electrochemical sensing platform, and the resulting Pd@rGO/GCE was successfully used for the sensitive and selective detection of Zn 2+ . The morphology and structural properties of the nanocomposite were systematically characterized using Fourier transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. Cyclic voltammetry and electrochemical impedance spectroscopy were used to confirm improved electrochemical performances of the modified electrode. The sensor was linear with a detection range of 2.0–200.0 µM with a low limit of detection of 1.7 nM for Zn 2+ analysis using differential pulse anodic stripping voltammetry. Moreover, the practicability of the Pd@rGO/GCE was proved by the precise Zn 2+ determination in drinking water sample.

Zn 2+ /Ge 4+ heterovalent co-substitution enables charge compensation and modifies the Er 3+ crystal field in garnet solid solutions. • Upconversion intensity of Er 3+ is enhanced over 4-fold for green emission and 3-fold for red emission. • The FIR thermometry exhibits excellent performance, achieving S r = 1.20% K −1 (@298 K) and δT ∼0.41 K. Heterovalent cation co-substitution is an effective strategy to regulate the crystal field and luminescence in rare-earth-doped phosphors. Here, Er 3+ -activated garnet solid solutions Gd 3 Zn x Ga 5–2 x Ge x O 12 ( x = 0.5–2) (GZG 5–2 x G) were synthesized via the solid-state reaction. A Zn 2+ /Ge 4+ pair was introduced to replace two Ga 3+ ions, enabling charge compensation and modifying the crystal field of Er 3+ . With Zn 2+ /Ge 4+ composition variation, the upconverison of green emission dominates at x = 0.5, while red emission peaks at x = 1. The Zn 2+ /Ge 4+ co-substitution significantly enhances luminescence, with GZG 4 G:10%Er 3+ and GZG 3 G:10%Er 3+ exhibiting over 4-fold (green upconversion) and 3-fold (red upconversion) intensity enhancement compared to GZGG:10%Er 3 + . The optical thermometry was constructed over 298–573 K, with a maximum relative sensitivity (S r ) of 1.20% K −1 and a minimal temperature resolution (δ T ) of ∼ 0.41 K at 298 K. The results demonstrate that the Zn 2+ /Ge 4+ co-substitution effectively tunes the upconversion emission and thermometric performance of Er 3 + -doped garnets, offering a feasible strategy for optimizing garnet-based optical temperature sensors.

Aqueous zinc metal batteries are promising for safe and cost-effective energy storage. However, their practical application is limited by the intrinsic instability of the Zn/electrolyte interface, including water-induced hydrogen evolution, Zn corrosion, and dendrite-prone Zn deposition. Herein, glutaronitrile (GLN) is introduced as a multifunctional dinitrile additive to stabilize Zn metal anodes through coupled regulation of solvation chemistry and interfacial evolution. The polar C≡N groups of GLN can coordinate with Zn2+, to replace part of the water molecules in the primary solvation shell, thereby suppressing the activity of coordinated water. Meanwhile, uncoordinated C≡N groups act as hydrogen-bond acceptors to reorganize the surrounding water network, further suppressing free-water participation in hydrogen evolution and corrosion. This dual regulation optimizes the Zn/electrolyte interfacial environment, improves electrolyte wettability on Zn, homogenizes Zn2+flux, and promotes compact, dendrite-suppressed Zn deposition. Additionally, GLN promotes the formation of a chemically heterogeneous interfacial structure enriched with ZnF2in the inner region, which further protects the Zn surface and stabilizes the Zn plating/stripping process. The optimized ZHG6 electrolyte enables Zn||Zn symmetric cells to cycle stably for over 900 h at 1 mA cm−2and 1 mAh cm−2, while Zn||Cu cells maintain high Coulombic efficiency during long-term cycling. Furthermore, Zn||V6O13full cells exhibit enhanced cycling stability and rate capability, achieving stable operation for 3200 cycles at 5 A g−1. As evidenced in this work, dinitrile-based molecular additives provide an effective and scalable strategy to fabricate durable aqueous zinc metal batteries.
