Fast charging and low-temperature operation are essential for next-generation energy storage. However, high-energy batteries struggle to meet these demands as existing electrolytes cannot simultaneously deliver fast interfacial kinetics, high ionic conductivity and favourable interphase formation. Prevailing strategies focus on weakening thermodynamic solvation, yet this approach does not directly address the kinetic bottleneck, that is, the desolvation barrier governing interfacial charge transfer. Here we reveal that the desolvation kinetics are dictated by dynamic solvent exchange rather than thermodynamic solvation energy. Guided by this mechanistic insight, we have formulated an electrolyte in which two anions carry distinct anionic potentials: high-anionic-potential anions form contact ion pairs that accelerate solvation-exchange kinetics, while low-anionic-potential anions form solvent-separated ion pairs that sustain high bulk ionic conductivity. The electrolyte enables fast charging and low-temperature operation in high-loading lithium-ion batteries. The design principle was further validated in aqueous aluminium-ion electrochemical systems, underscoring its broader relevance to sustainable, resource-abundant battery chemistries beyond the lithium ion. Together, our findings establish a new electrolyte design paradigm that decouples interfacial and bulk transport properties and expands the design space of battery electrolyte systems.

Electrochemical hydrogenation of biomass-derived substrates offers a sustainable route to valuable chemicals, yet conventional systems often struggle to simultaneously achieve high efficiency and high product purity. Here we report an electrochemical process based on a porous solid-electrolyte reactor that integrates efficient hydrogenation with intrinsic purification for biomass-derived substrates, thereby eliminating the need for supporting electrolytes. The system promotes the hydrogenation of maleic acid solution (a model unsaturated biomass substrate) into succinic acid (a model saturated biomass substrate), via a cation shielding effect while suppressing competing reactions such as hydrogen evolution. By continuously recycling the generated sodium succinate from the cathode to the middle layer, the reactor further converts it into pure succinic acid, establishing a closed-loop alkali-metal-cation shuttle that enhances selectivity and minimizes side reactions. This system delivers succinic acid Faradaic efficiencies ~ 85%, long-term operational stability (over 500 hours), and a final solution of > 98% purity, without downstream electrolyte recovery. These results highlight a scalable pathway toward cleaner, more efficient electrochemical upgrading of biomass.

Achieving uniform zinc deposition is crucial for high-performance
aqueous zinc-ion batteries, yet it remains a significant challenge.
While functional separators based on metal–organic frameworks
(MOFs) like UiO-66-NH 2 offer a promising route to regulate
ion flux, their effectiveness is often hampered by the energy-intensive
synthesis of MOFs and their poor dispersion within polymer matrices.
Herein, we report a rapid, room-temperature ultrasound-assisted synthesis
that yields UiO-66-NH 2 with a unique surface-fused morphology
and a hierarchical pore system within just 1 h. Unlike its conventional
counterpart with a well-defined octahedral shape, this ultrasound-induced
MOF (U-UN) forms a homogeneous and tightly integrated composite with
cellulose nanofibers, constructing a separator with optimized ion-transport
channels and interfacial stability. The U-UN-based separator demonstrates
superior ionic conductivity and Zn 2+ transference number,
effectively guiding the preferential growth of Zn along the (002)
plane. Consequently, a Zn||Zn symmetric cell equipped with this separator
achieves an ultrastable cycling life exceeding 1180 h, and a Zn||MnO 2 full cell retains nearly 100% capacity after 600 cycles at
1 A g –1 . This work not only presents a green and
efficient synthesis strategy for advanced MOFs but also provides fundamental
insights into the design of functional separators through microstructure
engineering for long-lasting metal batteries.

A multifunctional composite, designated as ZIF-8@LY/ZIF-8@CDs-Eu 3+ , was rationally designed as a fluorescence probe and high-performance photocatalyst for simultaneous detection and degradation of oxytetracycline (OTC). To address the critical challenge of co-encapsulating fluorescein (LY) and Eu 3+ -functionalized carbon dots (CDs-Eu 3+ ) within a single porous particle without functional incompatibility, we proposed a core-shell ZIF-8 architecture, where the etched ZIF-8 core served as the host for LY loading, and the in situ grown ZIF-8 shell was introduced to immobilize CDs-Eu 3+ . The acetic acid etching of the ZIF-8 core created abundant sites to absorb more LY molecules, which further enhanced the OTC removal efficiency. On this basis, a fluorescence “turn-on” ratiometric quantitative detection platform for OTC was established, with a low limit of detection (LOD) of 1.8 nM. Meanwhile, the ZIF-8@LY/ZIF-8@CDs-Eu 3+ composite achieved 99% OTC removal within 300 min under light irradiation, driven by the generated reactive species including superoxide radicals (·O 2 − ), hydroxyl radicals (·OH), and photogenerated holes (h + ). Notably, three parallel degradation pathways of OTC were identified via high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS). This work not only provides an innovative strategy for the design of multifunctional MOF-based composites, but also opens a new avenue for the efficient monitoring and elimination of antibiotic residues in complex environmental matrices.

Copper nanoparticles (Cu-NPs) are widely used in aquaculture for their growth-promoting and immunoenhancing properties. However, excessive or over-accumulated Cu-NPs in aquaculture water cause toxicity through waterborne immersion. To explore the toxicity effects of waterborne Cu-NPs on yellowtail kingfish (Seriola aureovittata), a 7-day exposure experiment comprising a control group (no Cu-NPs), a low-concentration group (0.120 mg/L), and a high-concentration group (0.384 mg/L) was conducted, followed by a 7-day recovery period without Cu-NP stress. Exposure to Cu-NPs significantly elevated antioxidant enzyme activities (GSH-Px, Cu/Zn-SOD) and thiobarbituric acid reactive substances (TBARS) level in liver and posterior kidney, indicating significant oxidative stress. In the liver, levels of epinephrine and diacylglycerol were significantly upregulated, the cAMP signaling pathway was disrupted, and the NF-κB signaling pathway was activated, along with the downregulation ofap-1anderk1-2and upregulation ofgadd45β, reducing cell proliferation and viability. These alterations resulted in hepatocellular vacuolation and blurred outlines of hepatic lobules. In the gill, high-concentration Cu-NPs activated oxidative phosphorylation, phagosome, and cell-adhesion molecules pathways and downregulated genes related to cell proliferation, adhesion, and tight junctions (i.e.,l1cam,camd1,cntn1,cdh2, andnectin1), leading to cellular vacuolization and epithelial separation in histology. These changes disrupted osmotic balance and significantly upregulated Na+/K+-ATPase activity. All histological damages were not fully recovered within the tested recovery period. Therefore, under conditions of continuous exposure, the concentration of Cu-NPs used for juvenile yellowtail kingfish in aquaculture should be kept below 0.120 mg/L, with a recovery period exceeding 7 days. These results reveal the toxicity mechanisms of Cu-NPs and provide a scientific basis for establishing safe application guidelines in yellowtail kingfish aquaculture.

The electrocatalytic formaldehyde oxidation reaction (FOR) on copper–based catalysts enables anodic hydrogen production and serves as an alternative to the oxygen evolution reaction by lowering the voltage requirement for water electrolysis. However, Cu–based electrocatalysts are constrained by a narrow operating potential window that limits attainable current densities, while insufficient long–term stability further restricts practical application. Herein, simultaneous enhancement of activity and stability is achieved by fabricating rough copper nanosheets on nickel foam (Cu–NF). The rough copper nanosheets increase the density of accessible active sites, enabling current densities up to 500 mA·cm −2 at 0.45 V vs RHE within the limited operating potential window. Moreover, the mechanically robust nickel foam scaffold helps preserve electrode integrity during prolonged anodic operation, while the dynamic Cu 0 /Cu+ surface evolution in the catalytic layer supports sustained activity, enabling stable operation for over 200 h. This work provides a general design guideline for achieving a balanced improvement in activity and durability of copper–based electrodes for formaldehyde oxidation.

The solid–liquid–gas triple-phase interface in the CO2 electro-reduction reaction (CO2RR) is pivotal for determining catalytic activity and selectivity, as it influences both the kinetics and thermodynamics of the reactions. However, observing this interface in situ is challenging because it forms at the interface among the solid catalyst, the flowing electrolyte, and the turbulent CO2. To address the issues, we achieved unobstructed in situ Raman observations at the microscale by developing a straightforward catalyst-integrated gas diffusion electrode (GDE). This monolithic GDE, featuring a biomimetic hydrophobic structure, fully releases the triple-phase interface─an essential prerequisite for enabling the in situ detection. Characterizations reveal that the microenvironment at the triple-phase interface significantly enhances multicarbon (C2+) selectivity. Furthermore, using advanced in situ 3D Raman tomography, we successfully visualized the spatial distribution of the triple-phase interface with high precision. The integration of in situ Raman spectroscopy with computational modeling has provided invaluable insights into the evolution of species within the microenvironment, elucidating a high local pH and rapid CO2 mass transfer at the triple-phase interface.

Aqueous zinc-ion batteries are regarded as energy storage devices with excellent development prospects, attributed to their high theoretical capacity, low cost, and favorable safety profile. Nevertheless, challenges such as severe dendrite and hydrogen evolution reactions on the zinc anode have significantly hindered the practical applications of aqueous zinc-ion battery devices. In this study, a Bi 2 S 3 -NC composite artificial interfacial layer was fabricated on the surface of the zinc electrode to modulate the thermodynamics and kinetics of zinc ion deposition/stripping reactions, thereby enabling a stable zinc anode. The experimental findings indicated that the hydrophobic Bi 2 S 3 -NC composite artificial interfacial layer could effectively suppress the occurrence of side reactions. Simultaneously, it regulated the desolvation ability of zinc ions and reaction kinetics, significantly reducing the nucleation energy barrier for zinc (the nucleation overpotential at a current density of 2 mA cm −2 decreased from 87.1 mV to 32.2 mV), thereby facilitating uniform zinc ion deposition. Ex-situ scanning electron microscopy (SEM) and in-situ optical microscopy characterizations further confirmed that the Bi 2 S 3 -NC protective layer could effectively inhibit the growth of zinc dendrites. Consequently, the modified Bi 2 S 3 -NC@Zn symmetric cell could cycle for more than 3200 h under the conditions of 2 mA cm −2 and 0.5 mAh cm −2 , and the overpotential was also significantly reduced (from 88.5 mV to 29.8 mV). Meanwhile, the Zn//Cu half-cell assembled with Bi 2 S 3 -NC@Zn could still maintain a coulombic efficiency of 99.69% after 270 cycles. Additionally, the full cell assembled with Bi 2 S 3 -NC@Zn and an Mn 2 V 2 O 7 cathode also demonstrated outstanding cycling stability (retained 115.7 mAh g −1 after 1400 cycles at 0.5 A g −1 ), far exceeding the 64.3 mAh g −1 of the bare Zn cell. This study proposes a simple and effective modification strategy for zinc anodes, providing a reference for the multi-dimensional improvement of zinc anode performance.

Developing efficient and durable electrocatalysts for the oxygen evolution reaction (OER) is crucial to advancing rechargeable zinc–air batteries (ZABs). In this work, we rationally design a series of Fe-doped double perovskite oxides (BaPrCo2−xFexO5+δ, denoted BPCF-x) to elucidate the interplay among Fe incorporation, lattice oxygen activity, and OER performance. Comprehensive structural and spectroscopic analysis reveal that Fe doping effectively tailors the electronic configuration and modulates the oxygen vacancy concentration, thereby accelerating charge transfer kinetics. Notably, BPCF-0.8 exhibits the lowest overpotential of 295 mV at 10 mA cm−2 and a Tafel slope of 45 mV dec−1, outperforming the pristine BPC catalyst. Optimized Fe incorporation promotes the lattice oxygen mechanism pathway while preserving structural integrity, as confirmed by OER tests in various pH electrolytes. Furthermore, the ZAB using BPCF-0.8 as the air cathode catalyst delivers high power density and excellent long-term durability, sustaining stable operation for over 500 h. This work elucidates how Fe doping activates lattice oxygen and balances oxygen vacancies, providing valuable insights into cation substitution engineering and lattice oxygen regulation in perovskite electrocatalysts.

A novel acridine-based fluorescent sensor (Sensor ANT) for the highly selective and sensitive detection of cyanide ions (CN−) was rationally designed and synthesized via the conjugation reaction of acridine-9-amine with 3-nitrophenyl isothiocyanate. The sensing mechanism is triggered by the specific interaction between exogenous CN−and the hydrogen-bonding moieties within the sensor’s molecular framework, which induces a distinct fluorescence quenching response. Systematic titration experiments confirmed that Sensor ANT exhibits rapid response kinetics, excellent selectivity, and reliable qualitative/quantitative detection capabilities toward CN−. Complementary biocompatibility assays, including in vitro cellular imaging and in vivo zebrafish experiments, further verified the promising application potential of this sensor in practical and biological detection scenarios. The detection limit (DL) of Sensor ANT for CN−was calculated to be 2.89 × 10−7M, with a 1:1 binding stoichiometry and a binding constant of 1.95 × 104M−1. These findings demonstrate that Sensor ANT represents a robust candidate for CN−detection in environmental and biological systems.

Electrochemical nitrate reduction to ammonia (NO 3 RR)
is a sustainable strategy that integrates environmental remediation
with ammonia resource recovery. Current NO 3 RR studies mainly
focus on high nitrate concentrations under idealized electrolyte conditions
to achieve high ammonia yields. Under realistic water conditions,
low NO 3 – concentrations, neutral media,
and competing side reactions often result in sluggish kinetics, low
removal efficiency, and undesirable nitrite accumulation. Herein,
we report a facile strategy for constructing an interface-tunable Cu/Cu 2 O@CoO-P heterojunction
through one-step regulation of the growth of CoO nanoneedles on copper
mesh by tuning the phosphorus concentration. Phosphorus incorporation
effectively modulates the electronic structure of the Co active sites
and tunes the heterojunction interface, thereby optimizing the generation
of adsorbed hydrogen (*H) and suppressing the hydrogen evolution reaction.
This enables a well-matched two-step tandem pathway, where Cu/Cu 2 O facilitates the conversion of NO 3 – to NO 2 – , and the P-modulated CoO sites
rapidly hydrogenate NO 2 – to NH 4 + , thus effectively preventing excessive NO 2 – accumulation. The optimized Cu/Cu 2 O@CoO-P achieves a high Faradaic efficiency
(FE) of 97.11% for NH 4 + - N and an ammonia yield
of 36.09 mg h –1 cm –2 at 10 mA
cm –2 under neutral-pH conditions, along with excellent
stability, retaining 98.45% of its performance after 20 cycles. Notably,
the catalyst demonstrates exceptional practical applicability for
ammonia recovery from real aquaculture tailwater in both batch mode
and continuous-flow mode. This work offers new insights into the design
of tunable heterojunction interfaces to achieve a well-matched and
efficient tandem catalytic process, enabling effective remediation
of low-concentration nitrate contamination and high ammonia recovery
in real wastewater environments.

Chitosanases are attractive biocatalysts for producing bioactive chito-oligosaccharides (COS), but their applications are limited by insufficient catalytic efficiency, poor stability, and challenging recovery. Although many chitosanases can be activated by metal ions, the direct addition of free ions into reaction systems suffers from low efficiency and separation challenges. This study presented a MOF-based strategy to create a Cu-enriched coordination microenvironment, enabling simultaneous immobilization and activation of marine polysaccharide hydrolases. Taking chitosanase OUC-CsnCA as a model, the immobilization on Cu-trimesic acid (Cu-BTC) doubled its activity (413.5 ± 34.7 U/mg) and increased k cat from 361.8 ± 8.0 to 704.4 ± 16.1 min −1 , along with improved thermostability and pH tolerance. MALDI-TOF-MS and HPLC confirmed deeper substrate depolymerization upon immobilization. Kinetic and spectroscopic analyses revealed that Cu 2+ -binding modulated enzyme conformation and promoted enzyme–substrate interactions. Molecular dynamics simulations further indicated that Cu 2+ coordination was associated with adjustments in catalytic cleft geometry (D102–E84) and reinforcement of hydrogen-bond interactions within the substrate-binding pocket. Enhanced activities were further observed for immobilized ι-carrageenase and α-agarase, demonstrating the potential applicability of this strategy to other metal-responsive marine polysaccharide hydrolases.
