Chlortetracycline (CTC), a broad-spectrum veterinary antibiotic, poses serious risks to human health through bioaccumulation due to excessive use. To address the critical need for CTC monitoring, we developed a fluorescence quenching lateral flow immunoassay (FQ-LFIA) employing black bimetallic hollow nanoparticles (BBHNPs) as quencher. BBHNPs were engineered with a unique dual-advantage architecture: an internal hollow structure for enhanced light capture capability and an external polydopamine layer for higher spectral overlap with fluorophores. This design resulted in exceptional photophysical characteristics, including a remarkable molar extinction coefficient (2.18×10 12 L mol -1 cm -1 ) and an unprecedented fluorescence quenching constant (5.20×10 13 L mol -1 ). BBHNP-based FQ-LFIA achieved a limit of detection (LOD) of 0.32 ng mL -1 , representing a 6.91-fold improvement over conventional gold nanoparticle-based lateral flow immunoassay (LFIA). Validation studies in spiked milk samples showed excellent recovery rates (87.73-118.09%) with high precision (coefficient of variation < 10.36%). Method comparison with liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis confirmed the reliability of BBHNP-FQ-LFIA for real-world applications.

High-efficiency and low-cost oxygen evolution reaction (OER) catalysts are essential for advancing water electrolysis technologies. Transition metal thiophosphates (TMPSs) have garnered considerable interest in the OER field due to their ability to modulate the electronic states of active atoms through surface defect engineering. In this study, monolayer theoretical calculations reveal that the interaction between adjacent single-double sulfur vacancies (S-DSVs) significantly alters the electronic structure of phosphorus atoms, thereby tuning the binding strength with reaction intermediates and effectively lowering the energy barrier of the rate-determining step. As a result, S-DSVs outperform isolated single sulfur vacancies (SSVs) and double sulfur vacancies (DSVs). Single-layer FeNiP 2 S 6-x (SL-FeNiP 2 S 6-x ) catalysts with uniformly distributed S-DSVs were successfully synthesized via a mild and selective etching process using B(OH) 3 . Electrochemical measurements demonstrate that SL-FeNiP 2 S 6-x with an optimized S-DSV concentration delivers excellent OER performance, achieving a low overpotential of 171 mV at 10 mA cm -2 and a Tafel slope of 38 mV dec ‑1 in 1 M KOH—surpassing most reported iron/nickel-based OER catalysts. This work introduces a novel strategy for enhancing electrocatalytic activity by precisely controlling the position and distribution of sulfur vacancies through controllable etching.

Tungsten and fluorine are critical to clean energy and semiconductor technologies, yet their frequent co-occurrence in complex ores creates long-standing barriers to efficient and sustainable utilization. Current extraction routes are hampered by severe mutual interference, with substantial tungsten losses entrapped in fluorite concentrate and concomitant fluorine losses retained in tungsten products. Here we present two complementary strategies that enable the simultaneous upcycling of fluorine and tungsten through phase-selective transformation. In the first route, fluorogypsum produced during HF synthesis from tungsten-bearing fluorite, is treated with H 2 O 2 , where peroxo coordination selectively leaches tungsten while stabilizing calcium sulfate; this achieves tungsten recoveries above 95 % at 30 °C and converts waste into environmentally benign gypsum. In the second, tungsten-bearing fluorite is directly decomposed in an H 2 SO 4 -H 3 PO 4 system with added F − , which preferentially complexes Si in the feedstock without consuming fluorine from CaF 2 , thereby suppressing CaF 2 dissolution and CaSO 4 ·2 H 2 O formation under acidic conditions and enabling selective tungsten extraction of up to 95 % while producing a high-grade fluorite concentrate (98.6 % CaF 2 ). Mechanistic studies reveal that the selectivity arises from competitive coordination and solubility control between tungsten- and calcium-bearing species. By coupling mineralogical insight with tailored reaction chemistry, this dual-pathway enables co-recovery of tungsten and fluorine from fluorite-scheelite ores, offering an environmentally benign and streamlined route to sustainable processing of coupled critical elements.

The K-CP/MnO 2 composite was prepared by loading manganese dioxide (MnO 2 ) nanosheets onto potassium hydroxide (KOH) activated carbonized polyaniline (K-CP) via low-temperature hydrothermal reaction. The composite demonstrated high efficiency in removing Pb 2+ and Zn 2+ in the hybrid capacitive deionization (HCDI) technology. K-CP/MnO 2 presents a core-shell structure with conductive K-CP as the core and electrochemically active MnO 2 constructed by porous nanosheets as the shell. The disordered entanglement of K-CP and MnO 2 nanoflakes significantly increases the interlayer spacing, optimizes the pore distribution, creates favorable conditions for charge and ion transport, and realizes the synergistic effect of electric double layer (EDL) adsorption and Faradaic reactions. The specific capacitance (SC) of K-CP/MnO 2 at 5 mV s −1 is 112.03 F g −1 , which is nearly 3.76 times that of CP (29.82 F g −1 ). At a voltage of 1.2 V (100 mg L −1 ), the electrosorption capacity (SAC) of the K-CP/MnO 2 electrode for Pb 2+ and Zn 2+ is 124.66 and 96.86 mg g −1 , respectively. After 15 adsorption/desorption cycles in the HCDI device, the adsorption capacity for Pb 2+ and Zn 2+ is retained at 86.81% and 82.59%, respectively. The experiments indicate that the removal of Pb 2+ primarily occurs through electrosorption, redox reactions, and surface complexation, while Zn 2+ is inserted into the channel provided by MnO 2 and participates in the solid phase reaction. The K-CP/MnO 2 composite prepared in this study offers a novel approach for designing high-performance HCDI electrodes and achieving the selective removal of heavy metals.

The rapid advancement of flexible and integrated smart electronic devices creates an urgent demand for flexible, transparent, and stretchable multifunctional energy storage devices. However, the development of multifunctional integrated energy storage devices faces significant challenges, including insufficient electrode deformation tolerance during repeated stretching and the detachment of active electrode materials, leading to degraded electrochemical performance and reduced transparency. Here, we report a self-supporting serpentine nickel micromesh (SNM) with high transparency ( T = 90.5%) and excellent mechanical stretchability, exhibiting only a 16% increase in sheet resistance after 200 cycles at a 50% elongation. Based on the transparent and stretchable SNM, we further fabricate self-supporting, transparent, and stretchable SNM@NiCoP cathodes and SNM@Zn anodes by electrodepositing NiCoP nanospheres and Zn nanosheets, respectively. The electrochemical deposition technique firmly integrates the stretchable conductive SNM with highly reactive materials, ensuring stability under deformation. The assembled transparent and stretchable alkaline zinc-ion batteries (TSA-ZIBs) deliver a specific capacity of 5.7 μAh cm −2 at a current density of 0.6 mA cm −2 . The TSA-ZIBs achieved an optical transmittance of 54%, with a capacity retention rate of 69.6% after 150 cycles at a 20% elongation, demonstrating excellent mechanical stretchability and electrochemical performance. This work proposes a self-supporting, highly transparent, and stretchable electrode, offering new insights for the development of multifunctional integrated energy storage devices.

Nitrogen-doped carbon dots (N-CDs) exhibiting long-wavelength fluorescence were successfully synthesized via a one-step hydrothermal method using neutral red and thiosemicarbazide as precursors, specifically to address limitations in pyrophosphate (P 2 O 7 4− , PPi) detection. As an essential adenosine triphosphate (ATP) hydrolysis byproduct and disease biomarker, PPi quantification remains challenged by costly instrumentation and complex procedures in conventional methods. The synthesized N-CDs demonstrated optimal excitation/emission at 520/600 nm with a quantum yield (QY) of 4.8%, enabling rapid (1 min response time), selective PPi detection through fluorescence quenching. Quantitative analysis revealed a linear detection range of 1.38–85.60 μmol/L (R 2 = 0.9983) and low detection limit of 0.42 μmol/L. Practical validation in milk samples yielded excellent recovery rates of 95.26–105.74% with ≤1.86% relative standard deviation, confirming reliability in complex matrices. Critically, the N-CDs' deep-tissue penetration capability facilitated real-time monitoring of intracellular PPi dynamics in HeLa cells, while maintaining high biocompatibility. This work establishes multi-element doped carbon dots as both a cost-effective analytical alternative and a versatile platform for biomedical imaging applications.

In this study, a Pr–ZrSiO 4 pigment was synthesised using a solid-state method with Pr 6 O 11 , ZrO 2 and SiO 2 as raw materials and H 3 BO 4 as the mineraliser. Results demonstrated that as the temperature was increased from 1100 °C to 1400 °C, the H 3 BO 4 -containing Pr 0.08 Zr 0.92 SiO 4 sample underwent a distinct colour transition from yellow (1100 °C–1200 °C) to green (1250 °C–1400 °C). By contrast, the sample without H 3 BO 4 maintained a yellow hue between 1100 °C and 1400 °C. Transmission electron microscopy analysis revealed Pr 2 Zr 2 O 7 secondary phase dispersed in ZrSiO 4 of the green powders. The added H 3 BO 4 reacted with SiO 2 to form a borosilicate glass phase that exhibited a strong adsorption capacity for lattice oxygen, resulting in the generation of oxygen vacancies in ZrSiO 4 . To maintain valence balance, Pr 4+ (yellow) converted to Pr 3+ (green) and the secondary phase Pr 2 Zr 2 O 7 was formed in ZrSiO 4 . The valence state transition of Pr ions (Pr 4+ /Pr 3+ ) was the primary reason for the colour transition. The green pigment exhibited excellent high-temperature stability, showing potential application in the ceramic industry.

Flexible mechanoluminescence (ML) elastomers show significant potential for next-generation wearable electronics, artificial skin, advanced sensing, and human-machine interaction. However, their broader application has been hindered by challenges such as restricted emission wavelengths, inadequate repeatability, insufficient cyclic stability, and poor self-recovery. Here, we report an innovative and high-performance solar-blind ultraviolet ML elastomer by combining commercial polydimethylsiloxane (PDMS) and newly fabricated Sr 3 (BO 3 ) 2 :Pr 3+ phosphors, capable of generating intense ultraviolet-C (UVC) ML peaked at 272 nm under mechanical stimulation. The composite elastomer exhibits exceptional repeatability and cyclic stability, maintaining detectable UVC emission over 10,000 continuous stretching cycles (power intensity at the 1st cycle is ~6.2 mW m −2 ). It also demonstrates rapid and efficient self-recovery behavior, restoring 43.2% of its initial intensity within 1 s and 90.2% after 24 h. Combined experimental and theoretical analyses reveal that interfacial triboelectrification, involving electron transfer from the phosphor to the PDMS matrix, leads to the observed UVC ML emission. Leveraging the solar-blind nature and high photon energy of UVC light, we further demonstrate the feasibility of self-powered photonics applications. This work not only offers novel insights into the design of advanced UVC ML systems but also provides “power-free” solutions for important applications where UVC photons are essential, such as outdoor optical tagging and microbial sterilization.

Persistent luminescence (PersL) materials have unique long-term separable excitation-emission properties. In this study, intrinsic near-infrared (NIR) PersL of Ti 3+ is found at 760 nm in undoped Na 0·5 Y 0·5 TiO 3 (NYT) after being illuminated to room light or red LED illumination. The low symmetric monoclinic perovskite structure of NYT leads to energy level splitting of Ti 3+ into 2 E 1/2 and 1 E 2/2 , which generates a new PersL excitation peak at ∼650 nm. Direct electron transfer from excited Ti 3+ to oxygen vacancy is verified during the PersL charging process by X-ray photoelectron spectroscopy which avoids cross-band transition. Further, double band visible/NIR PersL is realized by introducing Pr 3+ into NYT (Na 0·5 Y 0·5 TiO 3 :Pr, NYT-Pr) at 614 and 760 nm, respectively. By observing the anti-Stokes PersL of Pr in NYT-Pr at 614 nm that is rechargeable at 660 nm, a phonon-assisted charging mechanism is proposed, in which Ti 3+ absorbs excitation and phonon energy to realize electron transfer to oxygen vacancy ( V O ). Based on single band PersL NYT and double band PersL NYT-Pr, triple modal optical information encryption was realized by applying their visible fluorescence/visible PersL/invisible NIR PersL properties, showing different levels of optical information. NYT-Pr integrates traditional visible PersL by naked eyes and invisible NIR PersL imaged by CCD camera together, and will find promising applications in modern optics and bio-optics.

Near-infrared phosphor conversion light emitting diode (NIR pc-LED) has important application value in plant growth, night vision imaging and biological detection. Its performance depends on the optimized design of fluorescent materials. Based on gadolinium gallium garnet (Gd 3 Ga 5 O 12 ), the near-infrared phosphors of Gd 2.5 (CaSn) 0.5 (InAl) 0.5 Ga 3.5-x O 12 : xCr 3+ (x = 0.01–0.09) were prepared by Ca 2+ -Sn 4+ /In 3+ -Al 3+ double ion pair synergistic substitution strategy. Under excitation of 450 nm blue light, the material exhibits broadband near-infrared emission covering the range of 650–1150 nm, with a quantum yield of 96.29 %. The material exhibits excellent thermal stability of luminescence and can maintain 82.4 % of the initial emission intensity at room temperature at 423K. The NIR pc-LED device based on this phosphor package achieved 67.37 mW output power and 16.68 % photoelectric conversion efficiency at 100 mA driving current. Application verification shows that the NIR pc-LED light source shows excellent performance in plant supplementary light, night vision security, information encryption and nondestructive testing applications. It fully proves that the broadband near-infrared emission of this series of phosphors can take into account multi-functional application scenarios and has broad development prospects.

Thermally conductive ceramics represented by boron nitride (BN) are the enabling materials for thermal management in modern electronics. However, their sintering processes are typically energy-intensive, involving ultrahigh sintering temperatures (generally >1700 °C), limiting practical applications. Herein, we introduce an energy-efficient preparation method that rapidly densifies hexagonal BN ceramics at room temperature within minutes. This approach drastically reduces energy consumption—by two orders of magnitude lower than that of traditional high temperature sintering methods, while maintaining the high density. The utilization of boric acid and water clusters facilitates plastic deformation and enhances mass transfer under hydrostatic pressure, significantly lowering the densification activation energy. Consequently, the room-temperature prepared BN ceramics achieve an exceptional thermal conductivity of 62 W m −1 K −1 , outperforming current low-temperature sintered ceramics. These densified bulk BN ceramics have been prototyped in electronic devices for efficient heat conduction, demonstrating great advantages for energy saving and sustainable production in next-generation electronics.

Multicolor mechanoluminescence (ML) materials have attracted growing attention for applications in anti-counterfeiting, smart skin, wearable electronics, and structural health monitoring. However, their widespread implementation remains significantly hindered by the scarce available compositions and harsh preparation conditions—typically requiring temperatures above 1000°C and protective atmospheres. Here, a facile, low-temperature, and atmosphere-free synthesis of calcium borate-based ML materials (Ca 2 B 2 O 5 and CaB 2 O 4 ) is achieved. The phase ratio of Ca 2 B 2 O 5 and CaB 2 O 4 is manipulated by adjusting the stoichiometric ratio of raw materials (H 3 BO 3 and CaO). The distinct tetrahedral and octahedral coordination of Mn 2+ in these phases gives rise to tunable ML emission spanning from green to orange (535–605 nm). When incorporated into polydimethylsiloxane (PDMS) elastomers, these materials exhibit remarkable multicolor ML suitable for multi-level optical encryption and motion visualization. The encrypted information remains hidden under daylight or UV illumination can be deciphered only through ML activation, while the stress-induced color variation enables real-time monitoring of joint movement. This work not only establishes a versatile route for the design of low-temperature, phase-tunable ML materials but also reveals promising applications in next-generation information security and intelligent motion-sensing technologies.
