The combination of DNA nanotechnology and nanopore sensing technology has greatly promoted research on target molecule or ion detection. The large solid-state nanopores/nanochannels show better mechanical stability and reproducibility, but metal ion detection in the large nanopores with diameters of hundreds of nanometers or several micrometers is rarely reported. Hence, it is meaningful and urgent to develop a large nanopore-based sensing platform for the detection of metal ions. Herein, we employed a salicylic aldehyde-modified DNA network in conjunction with a glass nanopipette (GN) with a diameter of hundreds of nanometers as a sensing platform for the detection of target metal ions. Upon the addition of different receptors with the amino group, the salicylic aldehyde could in situ specifically recognize and bind with Zn2+ and Al3, forming Schiff base-metal ion complexes at the four vertices of one face per nanocube unit. The steric hindrance effect of multiple Schiff bases and metal ion complexes leads to the blockage of internal structure and decrease of ion current in the GN. Owing to this signal amplification strategy, the detection limit of the target metal ion reaches a level of fM in the GN with a diameter of about 300 nm. In the future, this functional nanopore sensing platform is expected to realize highly sensitive detection for more biological metal ions by choosing appropriate receptors.

Constructing an artificial solid electrolyte interface (SEI) layer is an effective strategy to suppress dendrite growth and corrosion in aqueous zinc batteries (AZBs). However, 2D material-based SEI coatings are generally non-biodegradable, posing environmental risks due to their persistence in soil. This research introduces a starch/polyacrylamide (STA/PAAm) hydrogel membrane developed as a self-healing SEI layer for AZBs. The incorporation of biomass-derived starch endows the STA/PAAm hydrogel with excellent soil biodegradability, achieving complete degradation within 21 days. Meanwhile, its dual-network structure, reinforced by reversible Al3+ crosslinking, offers robust mechanical resilience, self-healing ability, and high ionic conductivity—presenting a sustainable alternative to conventional SEI materials. Theoretical calculations reveal that the hydrogel modulates Zn2+ solvation, forming a stable [Zn(H2O)4(STA)(AAm)]2+ configuration, which suppresses hydrogen evolution and promotes uniform Zn2+ deposition along the (002) plane. The STA/PAAm-coated Zn anode exhibits an extended lifespan of over 3000 h at 2 mA cm−2, significantly surpassing that of bare Zn (531 h). Paired with an AlVO-NMP cathode, the pouch-type full cell retains 87.2% capacity after 2000 cycles at 5 A g−1 and demonstrates remarkable flexibility, powering LEDs under bending and folding conditions. This work bridges high-performance energy storage with environmental sustainability, offering a green paradigm for flexible batteries.

In this work, dual-emission boron-nitrogen co-doped carbon quantum dots (B,N-CQDs) were synthesized by a micro-solvothermal method, and the prepared B,N-CQDs were used to detect Al 3+ and Fe 2+ . The doping of B elements changed the microstructure of CQDs and endowed them with a dual emission property (F 430 and F 500 ). The detection basis of Al 3+ and Fe 2+ with the B,N-CQDs were attributed to the reverse changes of double emission peaks( F 430 and F 500 ) and fluorescence intensity changes of B,N-CQDs, respectively. Besides, the limit of detection (LOD) of Al 3+ and Fe 2+ as low as 0.187 μM and 0.276 μM, respectively. In addition, B,N-CQDs were loaded onto filter paper to prepare a paper-based sensor for the detection of Al 3+ with the feature of being more portable and practical. Meanwhile, B,N-CQDs presented outstanding performance in the detection of Al 3+ in tap water and Fe content in ferrous sulfate tablets.

The fluorescence intensity of lomefloxacin and chlortetracycline hydrochloride were significantly enhanced after the complexation of the two antibiotics with Al 3+ and the synchronous fluorescence spectra of the two complexes could be well separated when Δλ = 70 nm. Based on the above facts, a new method combining Al 3+ sensitization with synchronous fluorescence spectrometry was developed to determine lomefloxacin and chlortetracycline hydrochloride residues in meat foods in this study. This study showed that the concentration of the two antibiotics had an excellent linear relationship with the synchronous fluorescence intensity in the range of 1–550 ng mL −1 and 5–1800 ng mL −1 . Detection limits of the two antibiotics were 0.0378 μg kg −1 and 0.3530 μg kg −1 , respectively. Recovery rates for lomefloxacin and chlortetracycline hydrochloride were 86.1 - 90.2% and 85.3 - 96.5% in meat samples, respectively. The novel synchronous fluorescence spectrometry established in the experiment had the advantages of high sensitivity, good selectivity, low detection limit, fast detection speed and high accuracy. It had been applied to the detection of lomefloxacin and chlortetracycline hydrochloride residues in meat with satisfactory results.

Composite solid-state electrolytes (CSEs) are highly promising for lithium-metal batteries (LMBs) but suffer from low ionic conductivity, limited mechanical strength, and unstable interfaces with lithium metal. A multi-functional perovskite filler, Li 0.33 La 0.56 Ti 0.95 Al 0.01 Zr 0.04 O 3 (AZ-LLTO), is incorporated into a solid polymer electrolyte. This filler is engineered via an Al 3+ /Zr 4+ co-doping strategy that synergistically optimizes bulk and grain boundary properties, enabling simultaneous enhancement of bulk ion transport and stabilization of the Li/electrolyte interface. Al 3+ doping generates oxygen vacancies facilitating Li + migration through the perovskite lattice, thereby enhancing bulk ionic conductivity. Concurrently, Zr 4+ doping suppresses La 3+ segregation at grain boundaries, reducing interfacial resistance and favoring Li + transport across grain boundaries. The resultant AZ-LLTO-based composite solid electrolyte achieves a high room-temperature ionic conductivity of 2.3 × 10 −4 S cm −1 , a Li + transference number of 0.42, and stable Li deposition/stripping in Li/CSE-AZ-LLTO/Li symmetric cells for over 3100 h at 0.1 mA cm −2 . Thus, LiFePO 4 /CSE-AZ-LLTO/Li battery delivers an initial capacity of 146.9 mAh g −1 at 0.2 C and retains 85% of its capacity after 200 cycles, demonstrating the practical viability of this designed co-doped perovskite filler. Our work establishes a rational co-doping paradigm for perovskite-based fillers to concurrently enhance bulk conduction and interfacial compatibility in CSEs for next-generation LMBs.

A rapid and sensitive ratiometric fluorescence nanosensor for the detection of norfloxacin was obtained, where the yellow-emitting CdTe quantum dots (QDs) were as an internal reference and aluminium ion (Al³⁺) chelated on the QDs surface as the sensing unit. The nanosensor was characterized by transmission electron microscopy, Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy. As the concentration of norfloxacin increased, the sensor exhibited a continuous fluorescence color transition from yellow to blue. The CdTe-Al³⁺ QDs sensor demonstrated a low limit of detection of 6.6 nM. The ratiometric fluorescence sensor was also integrated with a smartphone color recognizer for visual and quantitative detection of norfloxacin with a limit of detection of 1.57 µM. This sensing platform exhibits excellent sensitivity, selectivity, and anti-interference performance, and it has great potential for on-site and quantitative analysis.

In this study, a novel imidazole-Schiff base fluorescent probe, EBI, was designed and synthesized. The molecular structure of EBI was systematically characterized by FT-IR, 1 H NMR, 13 C NMR and HR-MS. This study found that this probe could exhibit highly sensitive and selective fluorescence responses to Al 3+ in an EtOH/H 2 O (1:1 v/v) mixed solvent. The optical properties of EBI were systematically investigated using fluorescence spectroscopy and UV-Vis absorption spectroscopy. The results showed that the binding of EBI with Al 3+ could trigger a significant fluorescence enhancement effect, reaching a stable state within approximately 10 min, and that the interference from other common metal ions could be ignored. To further clarify its mechanism of action, various methods, including the Job plot, Benesi-Hildebrand experiment, 1 H NMR titration, and DFT calculation, were employed to thoroughly investigate the coordination behavior of EBI with Al 3+ . The study demonstrated that EBI and Al 3+ formed a complex in a 1:1 molar ratio, with a detection limit (LOD) of 74.75 nM. The fluorescence quenching of EBI–Al 3+ by PO 4 3− was also evident in the selected anion range. These results, based on the fluorescence “OFF-ON” mechanism, enable us to construct various types of molecular logic gates. This sensing system is capable of on-site, trace-level, real-time, and rapid detection of Al 3+ . Graphical

Sodium iron pyrophosphate (NFPP) is a cost-effective and safe cathode material for sodium-ion batteries (NIBs). However, NFPP suffers from low electron conductivity and sluggish Na+ diffusion kinetics, resulting in a poor rate capability. Here, we show that partial co-substitution of V3+ and Al3+ for Fe2+ synergistically enhances the rate capability of NFPP with improved Na+ storage capacity. The V3+/Al3+ co-substitution narrows the band gap energy of NFPP from 2.99 to 1.53 eV to increase electron conductivity, reduces Na+ diffusion energy barrier from 0.529 eV to 0.398 eV to enhance Na+ diffusivity, leads to the formation of Na vacancies to further facilitate Na+ transport, and improves Na+ storage capacity is because of enhanced electroactivity of the Fe2+/Fe3+ couple. At 0.1, 5 and 10C, the Na+ storage capabilities of the V3+/Al3+ co-substituted NFPP cathode are 120, 85 and 72 mAh g−1, respectively. At 5C, this electrode maintains 81% capacity after 1000 cycles. A full cell fabricated with the co-substituted NFPP as the cathode and a commercial hard carbon (HC) as the anode delivers a Na+ storage capacity of 87 mAh g−1 with 77% capacity retention after 100 cycles at 1C, outperforming a counterpart full cell fabricated with NFPP as the cathode and the anode and electrolyte.

A pillar-like 3D lanthanide-organic framework (Eu-MOF) with opposite chirality was assembled according to previous report and fully characterized. The Eu-MOF exhibits excellent luminescence and structural stability in the aqueous solution or other organic solvents and good pH-independent luminescence stability in the pH range of 3–12. It is important to point out that the as-synthesized Eu-MOF can be developed as a highly selective and sensitive luminescent probe to rapidly detect Fe 3+ (detection limit, 0.39 μM) and Al 3+ (detection limit, 0.084 μM) from mixed metal ions , which can be explained by different response mechanisms and the color change are visible to the naked eyes under UV-lamp. In addition, it also exhibits highly sensitive for nitrobenzene (NB) (detection limit, 0.013 μM). Considering the obvious spectral response and low limit detection, the Eu-MOF can be employed as a promising multi-functional luminescent sensor for sensing metal ions and small organic molecules in the future.

In this study, a novel fluorescent “turn-on” probe, (E)-N’-(2-(2-hydroxynaphthalen-1-yl) ethylidene)-2,5-diphenyl-2 H-1,2,3-triazole-4-carbohydrazide (G 4 ), was designed and synthesized, and fully characterized by various analytical techniques. Spectroscopic investigations revealed that G 4 exhibits excellent selectivity and sensitivity toward Al 3+ , with a 1:1 binding stoichiometry and a detection limit of 1.623 nM. Its advantages over existing probes include the lower detection limit and a distinct color reaction under UV light, which facilitates straightforward qualitative detection with lower cytotoxicity. The sensing mechanism was elucidated through density functional theory (DFT) and quantum chemical calculations. Then the practical utility of G 4 was demonstrated through recovery experiments in real water samples and its development into a portable test kit. Furthermore, cell experiments and zebrafish imaging confirmed its biocompatibility and applicability in biological systems with lower cytotoxicity. As a candidate drug that may be developed and utilized, the interactions of G 4 with two serum proteins (HSA and HIgG) were also investigated through spectrofluorometric and molecular docking analysis, revealing hydrogen bond or van der Waals forces as the main mode of action, suggesting potential for further biomedical applications. These results highlight G 4 as a highly sensitive, selective, and dual-functional fluorescent probe with significant potential for environmental monitoring and biological sensing.

The exploration of highly efficient deep-red luminescent materials is crucial for advancing white light-emitting diodes (LEDs), indoor plant growth, and polycrystalline silicon solar cells. Here, we realize sharp deep-red emission from interstitial Sm 2+ in silica through a dual-function Al 3+ /B 3+ codoping strategy. The interstitial Sm 2+ exhibits a dominant emission centered at 683 nm with a broad excitation band ranging from 250 to 550 nm. The co-introduction of Al 3+ and B 3+ facilitates the phase transition from α -quartz to α -cristobalite, which is more favorable for samarium accommodation, as revealed by density functional theory (DFT) calculations. Meanwhile, the co-introducing of Al 3+ and B 3+ increases the amount of Sm 2+ as proved by the UV-Vis-NIR diffuse reflectance and X-ray absorption near-edge structure (XANES) spectra. These two factors synergistically enhance the emission intensity of Sm 2+ compared with that in the Al 3+ and B 3+ singly doped samples. Specifically, Al 3+ , B 3+ and Sm 2+ doped α -cristobalite (SiO 2 :Al 3+ ,B 3+ ,Sm 2+ ) presents heat resistance up to 600°C and great water resistance abilities as proved thermally treated in air and hot-water immersion assessments. This work demonstrates a strategy to realize and enhance the Sm 2+ emission by interstitial occupation and microenvironment adjustment.

A novel bifunctional carbon dot (CD)–based sensing platform was constructed for detection of tetracyclines (TCs) and Al 3+ . The fluorescence CDs were fabricated by hydrothermal method using phenylenediamine ( p -PD) and ethylenebis(oxyethylenenitrilo) tetraacetic acid (EGTA) as precursors. The obtained prepared CDs show bright yellow fluorescence (y-CDs, E X = 400 nm and Em = 556 nm), high fluorescence quantum yield (QY = 21.55 ± 0.06%), and preferable optical stability. TCs can directly quench the fluorescence of y-CDs based on static quenching characteristics and a small internal filtration effect (IEF). By adding Al 3+ to the y-CDs + TCs system, the fluorescence is partly recovered because TCs escape from the surface of the y-CDs and form a more stable chelate with Al 3+ . The sensing platform displays good selectivity and high sensitivity to TCs and Al 3+ with low detection limits of 0.057–0.23 μM and 0.091 μM, respectively. Importantly, this sensing platform has enabled the detection of TCs and Al 3+ in milk samples with satisfactory recoveries and RSDs, confirming the reliability and feasibility of this method. Combining with low toxicity and preferable biocompatibility, the y-CDs are extended to cellular imaging and detection of CTC and Al 3+ in A549 cells. Graphical abstract
