Quenching mechanisms of AIZS and AIZS@SiO 2 core–shell nanoparticles were investigated. • Thermal quenching was mainly caused by the decomposition of organic ligands. • Chemical quenching was mainly resulted from the destruction of crystal structure. • Fluorescent quenching of hierarchical porous micro-nano surfaces was obviously improved. • Micro-nano hierarchical porous surfaces showed an application in information encryption field. Luminescence quenching is a common but undesirable phenomenon to quantum dots (QDs). However, systematic studies of quenching mechanism under harsh conditions are lacking. Herein, firstly, temperature-dependent PL intensity of Ag-In-Zn-S (AIZS) and their monodispersed silica-coated core–shell nanoparticles (AIZS@SiO 2 ) was conducted through thermal cycling experiments. PL intensity of AIZS QDs sharply decreased at 150 °C ( T q ), meanwhile a broad peak at 2932 cm −1 ascribed to C–H unit was detected. With continuously increasing temperature to 300 °C, this vibration band became stronger correspondingly, and PL intensity became weaker and weaker, providing direct support that thermal quenching was caused by decomposition of organic ligands. As expected, T q of AIZS@SiO 2 nanoparticles was increased to 250 °C owing to the thermal shielding of silica. Different from heating treatment, corrosive liquid seriously damaged crystal structure of AIZS QDs. XRDs pattern of AIZS@SiO 2 nanoparticles also became irregular after a longer treatment time, alkaline molecules still contacted core through mesoporous. Based on these findings, micro-nano hierarchical porous surfaces were constructed to trap air pockets for isolating luminescent component from harsh environments. With the helpful of thermal insulting property of air and silver mirror reaction, PL intensity was nearly unchanged even the functional surfaces were kept at 300 °C for 2 h and immersed into the strong alkaline solution for 24 h. The highly stable hierarchical porous surfaces showed good potential application in anti-counterfeiting and information encryption fields. Overall, this work provided theoretical insights in quenching mechanism of QDs and design guidance for QD with excellent robustness.

A key challenge in textile wastewater treatment lies in developing membranes’ tolerance both under acidic and high-salinity conditions. Taking advantage of the acid stability of amidine and reactivity of polyacrylonitrile (PAN), an innovative tight ultrafiltration (TUF) membrane with dual acid and salt resistance was prepared via the in-situ crosslinking of PAN with diamines. The optimized TUF membrane (PAN-HMDA) was simply prepared from solution of PAN crosslinked by 1,6-hexamethylenediamine (HMDA) through non-solvent induced phase separation (NIPS). Respective rejections of >99.5% and ∼5% for dyes exceeding 460 Da in molecular weight and salts (MgSO 4 , NaCl, and Na 2 SO 4 ) were achieved by PAN-HMDA with permeance of 20.5 LMH/bar. Notably, excellent Congo Red/salt separation selectivity was demonstrated by PAN-HMDA (α CR/MgCl2 = 175.2, α CR/MgSO4 = 316.7, α CR/NaCl = 318.0, α CR/Na2SO4 = 963.0). Stability tests confirmed its robust performance under harsh conditions, maintaining >99.4% rejection of CR after 60-day immersion in 2 M H 2 SO 4 or 2 M HCl. Meanwhile, stable performance was maintained after 48-h continuous filtration in 1 M H 2 SO 4 and under 80 g/L high-salinity conditions. Moreover, after simple washing with DI water, the FRR of PAN-HMDA for SA, HA and BSA were stabilized at 88.1%, 96.6% and 82.5%, respectively, showing considerable potential in treating real textile wastewater. This work paved a new way for efficient treatment of acidic and high-salinity textile wastewater.

Self-targeted strategy: PAHs as precursors for PAH adsorbents. • Monomer selection and carbonization tune porosity (up to 1893 m 2 g −1 ). • CP-NAP-800 captures 49.87% of 16 PAHs from real FCC diesel. Polycyclic aromatic hydrocarbons (PAHs) in FCC diesel were employed as building blocks to construct hypercrosslinked polymers via Friedel–Crafts alkylation. KOH-activated carbonization yielded porous carbons with high surface areas (590–1893 m 2 ·g −1 ) and hierarchical microporosity. The optimized adsorbent, CP-NAP-800 (carbonized at 800 °C), exhibited exceptional adsorption for naphthalene (21.77 mg·g −1 ), anthracene (105.14 mg·g −1 ), and acenaphthylene (30.65 mg·g −1 ). Adsorption followed Langmuir and pseudo-second-order kinetics, indicating monolayer π–π stacking interactions with graphitized carbon. In real FCC diesel, CP-NAP-800 achieved a total capacity of 355.88 mg·g −1 for 16 priority PAHs with 49.87% removal efficiency, and maintained stable performance over six cycles. This work presents a novel self-targeted strategy for PAH capture and recovery, where the pollutants themselves serve as precursors, offering a sustainable remediation approach for the petrochemical industry.

In recent years, with the development of electric vehicles and electric vessels, the issues of battery thermal safety have garnered significant attention. Composite phase-change materials (CPCMs) hold great potential as passive cooling systems in battery thermal management systems (BTMS), but their high flammability remains an unresolved challenge. This study successfully developed a flexible composite phase-change material, CPCM/P-CSF@rGO, by encapsulating a eutectic phase-change material composed of mannitol and galactitol in a three-dimensional hydrogen-bonded network, self-polymerised by phosphated corn straw cellulose (P-CSF) and reduced graphene oxide (rGO). The study demonstrates that the strong hydrogen bonding network formed between the phosphate groups introduced by phosphoric acid modification and rGO constructs highly efficient thermal conduction pathways, achieving a thermal conductivity of 1.039 W/(m•K) and significantly accelerating thermal response rates. Simultaneously, the incorporation of the P-CSF@rGO framework endows the material with excellent flexibility and shape stability. Due to the in-situ flame-retardant modification of the framework, the phase-change material maintains a high latent heat of phase-change (194.7 J/g) and achieves superior flame retardancy through gas-phase and condensation-phase mechanisms. It exhibits a limiting oxygen index of up to 30.64% and rapidly extinguishes itself when exposed to open flame in atmospheric conditions. Thus, the flexible composite phase-change material (CPCM/P-CSF@rGO) supported by a phosphorylated cellulose framework emerges as a promising candidate for ensuring safety and high performance in thermal management applications.

An ORR/EO-Cl system using commercial electrodes achieves efficient disinfection at 5 mA/cm 2 . • Cathodic H 2 O 2 consumes anodic free chlorine to generate 1 O 2 as the dominant bactericide. • The system suppresses chlorate and chlorite formation in real medical wastewater. • Multi-level oxidative damage to membranes, DNA, proteins and lipids causes irreversible inactivation. Electrochemical disinfection of chloride-rich medical wastewater faces an inherent trade-off: killing pathogens efficiently while avoiding toxic chlorate and chlorite formation. Here we show that coupling oxygen reduction at a commercial carbon felt cathode with chlorine evolution at a DSA@Ru/Ir anode breaks this trade-off. At 5 mA/cm 2 , cathodic H 2 O 2 rapidly consumes anodic free chlorine, generating singlet oxygen ( 1 O 2 ) as the dominant bactericidal species while suppressing chlorate and chlorite. In real hospital wastewater, chlorate drops from 0.66 to 0.39 mg/L, and the system inactivates 10 7 CFU/mL Escherichia coli in 5 min and Staphylococcus aureus in 10 min-using, the energy consumption was 0.1169 kWh/m 3 and 0.2338 kWh /m 3 , respectively. Quenching, flow cytometry, DNA electrophoresis, protein carbonylation and lipid peroxidation collectively confirm that 1 O 2 -driven oxidative stress causes irreversible membrane, DNA, protein and lipid damage. This work offers a low-energy, commercially viable strategy for electrochemical disinfection of real medical wastewater with intrinsic byproduct suppression.

Structural colors arise from wavelength-selective scattering in micro/nanostructures. The structural order governs the color brightness, saturation, and iridescence, but there is not yet a generalized framework to quantify the structural order. It remains unclear how the structural order quantitatively affects the reflection and absorption in structurally colored materials. Here, we co-assemble binary silica nanoparticles to tune the degree of order and quantify its impact on reflection and absorption. By varying compositions and particle size ratios, we can adjust the degree of order from long-range crystalline to short-range ordered states. Combining reflectance spectroscopy with ultra-small-angle X-ray scattering measurements, we establish an experimentally order parameter to distinguish long-range ordered, transitional, and short-range ordered regimes. Correlating structural order with optical absorption reveals that increasing disorder enhances scattering events and leads to larger absorption. In addition, increasing particle size further increases absorption by reducing the transport mean free path. This work demonstrates that the particle-size-ratio engineering serves as an effective route to tune the structural order, offering a general approach for tailoring both color appearance and absorption efficiency for designing novel photonic materials.

Functionalized nanosilica is used to carry agrochemical IAA via disulfide bonds. • Under GSH environment, SiO 2 -S-S-IAA exhibits significant redox responsiveness. • The -SH on the surface of SiO 2 can form complexes with various heavy metal ions. • Dual-functional nanocarrier allows sustained IAA release and capture of metal ions. Owing to the low efficiency and lack of target specificity in the application of agrochemicals, e.g., plant growth regulators, the resulting environmental pollution and resource waste have raised enormous concerns over environments and human health. Herein, a redox-responsive nanosilica carrier (SiO 2 -S-S-IAA) was developed for efficient release of 3-indoleacetic acid (IAA), by functionalizing the surface of nanosilica with 3-mercaptopropyltrimethoxysilane (MPTMS), followed by the covalent coupling of IAA via redox-cleavable disulfide bonds. Under the high level of glutathione (GSH) in the plant microenvironment, IAA was released in a controlled way through disulfide bond cleavage, thus achieving redox response. In vitro controlled-release experiments confirmed that the release amount of IAA was significantly higher in the environment of 10 mM GSH, more than 10 folds at pH 5.5. Meanwhile, the thiol groups generated after release could form complexes with various heavy metal ions (Hg 2+ , As 3+ /As 5+ , Cd 2+ , Pb 2+ ), with the highest adsorption efficiency towards Hg 2 + up to 57.95%. More importantly, in planta experiments under cadmium stress have demonstrated that SiO 2 -S-S-IAA not only promoted rice seedling growth but also significantly reduced Cd 2+ accumulation in shoots, effectively inhibiting its transfer to edible parts. This work establishes a dual-functional nanocarrier platform that combines targeted agrochemical delivery with in situ heavy metal immobilization, offering a promising strategy for sustainable and precise crop protection.

One-dimensional (1D) carbon fiber (CF) and two-dimensional (2D) MXene, with high strength and physical barrier properties separately, are expected to simultaneously realize a synergistic reinforcing effect as strengthening fillers in epoxy resin to protect steel structures. However, synergistic reinforcement is significantly limited by the chemical compatibility and dispersing state of fillers in resin due to the chemical inertness of CF and self-stacking properties of MXene. Inspired by the chemical structure of mussel’s foot filaments, Fe 3+ -tannic acid (Fe 3+ -TA) metal-phenolic networks (MPNs) were constructed on the surface of fillers. Herein, the 1D/2D CF/MXene synergistically reinforced coating was designed with enhanced performance by simultaneously incorporating TA/Fe 3+ @CF (TCF) and TA/Fe 3+ @MXene (TMX) into the epoxy matrix. In the coating, 1D TCF could resist impact, and 2D TMX could provide barrier properties. Erosion test results indicate the T(CF+MX)/EP showed a reduction in volume loss by 13.34% and 13.28%, as well as mass loss by 2.11% and 11.59%, respectively, compared to TCF/EP and TMX/EP. The | Z | 0.01Hz of T(CF+MX)/EP stayed at 1.15 × 10 9 Ω cm 2 even following 25 d of immersion under 60 MPa alternating hydrostatic pressure (higher than that of TCF/EP and TMX/EP). This study could provide insights for multiscale fillers design to utilize synergistic reinforcement with enhanced protective performance of coatings.

This study investigated the effects of moderate germination (4°C, 65%–75% RH, sprout length less than 1 cm) on the physicochemical properties and antioxidant capacity of raw and aged black garlics. Moderate germination significantly increased the contents of fructose, glucose, alliin, allicin, total flavonoids in raw garlic, which improved by 33.68%, 31.47%, 5.61%, 38.21%, and 90.91%, respectively. It also resulted in the obvious rise in alliin, total polyphenols, and total flavonoids in black garlic aged from germinated raw garlic, and rose by 29.01%, 26.96%, and 51.22%, respectively. The antioxidant capacity of germinated raw garlic and its aged black garlic was also significantly improved. While germination promoted the formation of 5-hydroxymethylfurfural (5-HMF) (increased by 55.47%) and inhibited the production of acrylamide (decreased by 49.91%) in aged black garlic. It did not significantly affect the color of raw and aged black garlics. Moderate germination is an excellent strategy to improve the nutritional contents and antioxidant capacity of raw and aged black garlics, which displays a promising alternative for developing functional foods from moderately germinated raw garlic and its aged product.

Driven by the global push for sustainable energy, supercapacitors are regarded as competitive energy storage systems. Nevertheless, boosting their energy density and cycling durability remain core challenges. Herein, a La 2 O 3 /Al 2 O 3 heterostructure (La-Al-O) is in-situ fabricated on nickel foam (NF) via a hydrothermal route. Electrochemical activation converts crystalline La 2 O 3 into amorphous La 2 O 3 , triggering structural reconstruction: interwoven nanosheet networks evolve into loose, crumpled nanosheets. This transformation enriches oxygen vacancies and generates Ni(OH) 2 on NF to create abundant ion-accessible active sites, while Al 2 O 3 serves as a structural stabilizer against framework collapse (activated La-Al-O, abbreviated A-La-Al-O). In terms of electrochemical performance, the A-La-Al-O/NF electrode exhibited a high specific capacitance of 4.60 F·cm −2 at a current density of 5 mA·cm −2 . After 20,000 cycles at a scan rate of 20 mA·cm −2 , the cycle retention rate was 75.7%. For the assembled asymmetric device (denoted as A-La-Al-O/NF/activated carbon (AC)), an energy density of 49.41 Wh·kg −1 was achieved at a power density of 889.38 W·kg −1 , with a cycle retention rate of 82.5% after 20,000 cycles. This study adopts method combining hydrothermal and electrochemical activation without the need for binders, featuring a simple and convenient process. It provides a new insight for the high-value utilization of rare earths and the development of high-performance supercapacitors.

Target gas selection was based on the GC–MS test of mango fruit during storage. • A 4-sensor array consisted of Pd-SnO 2 exhibited good performance for target gases. • The TabPFN model was used for mixed gas detection based on the sensor array. • The sensing mechanism was explained by characterization and DFT calculations. • Mango maturity identification was achieved by the sensor-algorithm integrated system. Plants maintain continuous gaseous exchange with their surroundings, and the volatile organic compounds (VOCs) they emit can act as indicators of plant physiological status. As an important plant organ, fruit maintains active physiological metabolism, including during the postharvest stage. Therefore, the detection of volatile compounds in postharvest fruits can be used to evaluate the quality and monitor their spoilage during storage and transportation. However, current gas detection instruments are mostly benchtop devices that are bulky and costly, making them unsuitable for practical industrial applications. Thus, developing gas-based rapid maturation assessment technologies for fruits is growing increasingly essential. In this study, we developed an intelligent monitoring system for fruit ripening process monitoring, with mangoes chosen as the research subject. Specifically, ethylene, ethanol, ethyl acetate and dipentene were identified as four target gases based on the detection results of VOCs released by mangoes during storage via solid-phase microextraction combined with gas chromatography–mass spectrometry. To detect these signals, a 4-sensor array was constructed using SnO 2 nanospheres functionalized with palladium nanoparticles, leveraging resistance variations to capture the dynamics of gases. Density functional theory calculations and comprehensive characterization were employed to elucidate the sensing mechanism. The Tabular Prior-data Fitted Network, a Transformer-based deep learning model, was used to analyze four target gases and their multicomponent mixtures. This method achieved high-precision classification (94.8%) for the gases and their mixtures, as well as accurate concentration regression (R 2 = 0.839) for the target components. Finally, the system was integrated into a portable platform, enabling the on-site identification of mango maturity across different storage durations. This work establishes a robust framework for sensor design and intelligent fruit quality monitoring. Download: Download high-res image (194KB) Download: Download full-size image

Metastable hcp-Ni enables the synthesis of highly dispersed and stable Ni/Al 2 O 3 catalyst • Highly dispersed Ni/Al 2 O 3 catalyst delivers 75.7% CO 2 conversion and 100-h stability • Original hcp-Ni particles spontaneously transform into fcc-Ni clusters of ∼2.3 nm • Small Ni clusters promote CO 2 methanation via monodentate formate intermediate • Fcc-Ni precursors undergo severe sintering to ultra-large and less-active particles Ni-based catalysts are promising candidates for CO 2 methanation while their practical applications are limited by particle agglomeration and deactivation. Here, we report a facile strategy to fabricate a highly dispersed and stable Ni/Al 2 O 3 catalyst using metastable hexagonal close-packed (hcp)-Ni as a precursor. Comprehensive characterization reveals that the initial hcp-Ni (∼12.0 nm) spontaneously transforms into uniform face-centered cubic (fcc)-Ni nanoparticles (NPs) of ∼2.3 nm on γ -Al 2 O 3 support during H 2 reduction and CO 2 methanation reaction. The small Ni particles contribute to improved Ni 0 proportion on catalyst surface. In contrast, the original fcc-Ni precursors are prone to sintering, forming ultra-large and less-active Ni aggregates. The highly dispersed Ni NPs derived from hcp-Ni enhance CO 2 adsorption-activation and facilitate the formate-mediated reaction pathway. The resulting hcp-Ni/Al 2 O 3 catalyst delivers a CO 2 conversion of 58.2% with a CH 4 selectivity of 85.4% at 460 °C and endows robust stability exceeding 100 hours. The optimal CH 4 space time yield reaches 179.5 mmol·g cat −1 ·h −1 , exceeding 2.4 times that of fcc-Ni/Al 2 O 3 . This work establishes a reliable synthesis paradigm rooted in crystal-phase regulation, enabling the manufacture of highly dispersed and stable Ni-based catalysts for efficient CO 2 methanation.
