Multi-functional integrated smart interface evaporator for seawater is widely viewed as highly promising technology to generate clean water. Herein, the scalable Junas ultra-black composite film with visible-light/electric/microwave triple-responsiveness was fabricated by spraying an ultra-black coating onto modified carbon nanotube film, enabling all-weather purification of seawater. Analysis of microstructure, morphology and performance revealed that the Junas structured ultra-black composite film possessed excellent hydrophilicity/hydrophobicity and hierarchical micro-nano three-dimensional porous structure, facilitating water transport via capillary effect and significant photothermal phenomenon with 51.2 °C under 1 kW/m 2 illumination. Consequently, the ultra-black composite film evaporator offered superior photothermal water evaporation performance with evaporation rate of 1.25 kg·m −2 ·h −1 , thermal conversion efficiency of 82.18 % and exceptional cycling stability, along with all-weather electrothermal seawater desalination with evaporation rate of 3.51 kg·m −2 ·h −1 and photo−/electrothermal seawater desalination with evaporation rate of 4.65 kg·m −2 ·h −1 . Additionally, the evaporator can effectively purify seawater, yielding water with metal ion concentrations significantly below the limits stipulated in the World Health Organization drinking water standards. Simultaneously, the hierarchical micro-nano porous ultra-black coating coupled with the highly conductive carbon nanotube layer endows it with outstanding electromagnetic shielding effectiveness of ∼48 dB in the 8–12 GHz band. This work presents a facile strategy for designing scalable, triple-responsive ultra-black composite film, achieving integrated all-weather desalination of seawater and electromagnetic protection through the synergistic integration of hierarchical micro-nano three-dimensional porous structure and hydrophilic carbon nanotube film.

Breast cancer therapy confronts dual challenges of metabolic plasticity-driven drug resistance and immunosuppression. To address this, we developed DCP-TPP, a therapeutic nanoplatform that integrates dysregulation of copper homeostasis and lipid metabolism for precise breast cancer therapy. Leveraging the overexpression of cluster of differentiation 36 (CD36) in breast cancer cells, DCP-TPP employs fatty acid camouflage (PCM) to deliver disulfiram (DSF) and photothermal Cu3BiS3 to cancer cells and features triphenylphosphonium (TPP) modification for targeted mitochondrial drug delivery. Near-infrared (NIR) irradiation triggers the phase transition of DCP-TPP’s outer layer, inducing spatiotemporal release of DSF to liberate copper ions from inert Cu3BiS3, thereby generating diethyldithiocarbamate–copper complex (CuET). This disrupts copper homeostasis and induces cuproptosis, which subsequently triggers S-acetyltransferase (DLAT) aggregation, impairing tricarboxylic acid (TCA) cycle flux, acetyl-CoA production, ATP citrate lyase (Acly)-dependent lipogenesis, and ultimately collapses mitochondrial oxidative phosphorylation. Multiomics profiling revealed oleic acid depletion, arachidonic acid oxidation, and glutathione exhaustion, collectively amplifying metabolic collapse. DCP-TPP-induced cell death enhanced dendritic cell (DC) activation and CD8+ T cell infiltration. In breast cancer models, DCP-TPP achieved 90.9% tumor suppression, with 60% of mice resisting rechallenge. By transforming lipid metabolic dependency into a therapeutic vulnerability and coupling it with copper ion toxicity, DCP-TPP offers a promising strategy for breast cancer therapy.

Combining light-stimulated actuators with large deformation and high sensitivity with superhydrophobic surfaces has great applications in emerging fields, such as smart bionics, microfluidic devices, and droplet manipulation. Here, using self-assembly and spray methods, light-responsive superhydrophobic films driven by UV light were prepared. Due to the low surface energy of polydimethylsiloxane (PDMS) and micronanostructures of ZnO, the film surface exhibited excellent superhydrophobicity. With the incorporation of light-responsive azobenzene groups, the film achieved a transition of azobenzene molecules from linear trans structures to bent cis structures under UV light irradiation. This change endowed the film with excellent driving properties, allowing the film to achieve bending angles of up to 90° under UV light irradiation with a power density of 70 mW/cm2. Additionally, the prepared light-responsive superhydrophobic films remained stable in bending tests, high temperatures, UV irradiation, and various organic solvent immersion tests. Based on the outstanding superhydrophobic and light-driven properties, light-responsive superhydrophobic films can be designed for applications in the fields of biomimetics and droplet manipulation.

Bi 2 Mo 2 O 9 : Yb 3+ /Tm 3+ /Ho 3+ phosphors were synthesized via solid-state reaction method. Structural characterization confirmed phase purity and effective rare-earth incorporation into the host lattice. Under 980 nm excitation, the materials exhibited distinct emission bands corresponding to Tm 3+ (477 and 690 nm) and Ho 3+ (542 and 657 nm). Through optimization of Ho 3+ concentration (0.5 mol%), white-light upconversion emission was obtained with CIE 1931 coordinates of (0.3147, 0.2805). Using fluorescence intensity ratio technique based on non-thermally coupled energy levels of Tm 3+ ( 1 G 4 ) and Ho 3+ ( 5 F 5 ), it was found that the material had excellent temperature sensing performance, achieving maximum sensitivities of 21.74 %K −1 (absolute) and 1.892 %K −1 (relative). Remarkably, the material exhibits temperature-dependent chromaticity shifts from white (303 K) to yellow (483 K), enabling visual temperature indication. The findings demonstrate that Bi 2 Mo 2 O 9 : Yb 3+ /Tm 3+ /Ho 3+ phosphors exhibit promising prospects in optical thermometry and thermally-responsive luminescent devices, particularly in scenarios where thermally-driven color variations are advantageous or tolerable.

Perovskite light-emitting diodes (PeLEDs) have achieved remarkable progress in recent years, with green-emitting PeLEDs now exhibiting external quantum efficiencies (EQEs) exceeding 30%, rivaling those of organic light-emitting diodes (OLEDs). While quasi-2D perovskite structures have emerged as a promising strategy for high-efficiency PeLEDs─owing to their enhanced exciton binding energies and charge carrier confinement─their phase distribution remains a critical yet challenging factor governing device performance. In this study, we demonstrate that the phase distribution in quasi-2D perovskite films is highly sensitive to the solvent atmosphere during annealing. Polar solvents (e.g., dimethylformamide, dimethyl sulfoxide) introduce nonradiative recombination centers and accelerate film decomposition, whereas nonpolar solvents (e.g., chlorobenzene) suppress degradation and promote high-n-phase purity. By employing nonpolar solvent vapor post-treatment, we achieve enhanced radiative recombination efficiency, yielding PeLEDs with a maximum EQE of 24.27%. Our findings highlight a previously overlooked aspect of perovskite film fabrication and provide key insights for the scalable production of quasi-2D PeLEDs.

Lead-free perovskites are becoming a focal point in the quest for non-toxic and stable materials for optoelectronic applications. Despite this interest, achieving blue light excitation from the lead-free halide double perovskite Cs 2 AgInCl 6 at room temperature remains a significant challenge, hindering their commercial viability. Here, we address this issue by synthesizing the rare earth lead-free double perovskite Cs 2 Ag 0.6 Na 0.4 In 0.8 Bi 0.2 Cl 6 :Yb, which demonstrates visible/near-infrared (NIR) light emission at 598 and 1,000 nm upon blue light excitation at room temperature. We show that this excitation stems from complex interactions between energy level splitting induced by Yb and self-trapped exciton energy levels. Notably, we observe that under blue excitation, the photoluminescence intensity increases with temperature. Furthermore, Cs 2 Ag 0.6 Na 0.4 In 0.8 Bi 0.2 Cl 6 :Yb is integrated into a blue-light-emitting diode, enhancing the conversion efficiency of GaAs solar cells as a down-shifting layer. Ultimately, this research opens new avenues for developing eco-friendly, efficient materials with significant implications for sustainable technology.

Semi-coke (SC), a solid waste generated from the dry distillation of oil shale, is rich in organic matter, classifying it as a functional carbon-based material. Combining the progressive advantages of functionalized carbon-based materials in advanced oxidation technology, this study prepared Fe-N co-doped semi-coke (Fe-N-SC) through a facile one-step pyrolysis of SC pre-impregnated with potassium ferricyanide. Under visible light (VIS) irradiation, Fe-N-SC was able to activate periodate (PI) to establish an Fe-N-SC/PI/VIS system for degrading norfloxacin (NOR). The results showed that this system achieved 99.5%-NOR removal, with a mineralization degree of up to 68.6%- within 30 min. Furthermore, Fe-N-SC exhibited stable performance over a wide pH range (3−9) and maintained high NOR removal efficiency in real water matrices, indicating its robustness and practical applicability. Electron paramagnetic resonance and free radical quenching experiments revealed that h + and ·OH were the primary species responsible for NOR degradation in Fe-N-SC/PI/VIS system. The proposed mechanism involved reactive oxygen species-driven oxidative cleavage of piperazine ring in NOR, leading to its stepwise breakdown and mineralization into harmless end-products. During the degradation process, no toxic intermediates were detected, highlighting the environmental safety of Fe-N-SC/PI/VIS system for sustainable and highly effective removal of antibiotics from aquatic environment.

This study aimed to elucidate how garlic-derived volatile compounds, particularly sulfur-containing odorants, dynamically migrate and accumulate within the complex matrix of light soy sauce over time. The volatile profiles at different migration intervals were analyzed using an electronic nose (E-nose) and gas chromatography-mass spectrometry (GC-MS). Systematic evaluations of differences in odor profiles and dynamic changes in volatile compounds were conducted through odor activity value (OAV) analysis and orthogonal partial least squares discriminant analysis (OPLS-DA). E-nose analysis demonstrated that prolonged migration times facilitated the transfer of sulfur-containing volatile compounds from garlic into light soy sauce, significantly increasing the response values of sensors TA/2 and T40/1 ( p < 0.05), thereby altering the aroma characteristics of the soy sauce. GC-MS analysis revealed that as migration time increased, the concentration of sulfur-containing volatile compounds(0 → 140000 μg/L) from garlic in light soy sauce significantly rose ( p < 0.05). OAV analysis suggested that the aroma profile of garlic-flavored soy sauce resulted from the combined contributions of sulfur-containing compounds and the major volatile components of soy sauce. VIP analysis based on OAV and OPLS-DA identified 18 key substances, including methyl valerate and isobutylbenzene, as the primary contributors to the differences among samples at various migration times. A key finding was the linear positive correlation observed between the migration quantity of garlic odor compounds migrating into soy sauce and migration time. This study enhances our understanding of the migration mechanisms of garlic flavor substances in light soy sauce.

The synthesized FeVO 4 /MXene composite photocatalysts demonstrated exceptional photocatalytic activity in activating PMS, removing 100% of 2,4,6-trichlorophenol (2,4,6-TCP) within 20 minutes. The incorporation of MXene effectively reduced photogenerated electron-hole pairs recombination in FeVO₄, enhancing charge transfer efficiency. Mechanistic studies revealed that synthesized FeVO 4 /MXene generated more •OH and ¹O₂ through the reaction between h⁺ and PMS. Furthermore, the photogenerated electrons (e⁻) facilitated Fe redox cycling within the system. The FeVO 4 /MXene/PMS/Vis system not only achieved efficient separation of photogenerated charge carriers but also reduced the required PMS dosage by 75%. Remarkably, the FeVO₄/MXene composite maintained its structural integrity after five consecutive cycles while retaining 98% of its initial degradation efficiency for 2,4,6-TCP, demonstrating excellent durability and promising application potential.

Photocuring-based three-dimensional (3D) printed hydrogels have versatile applications in various fields. However, the heterogeneous network with nanogel cross-linking points during free radical polymerization (FRP) often results in hydrogels that are unable to degrade or be reprocessed, significantly limiting their applications. Herein, a UV-curable reversible addition–fragmentation chain transfer (RAFT)-mediated hydrogel system compatible with digital light processing (DLP) 3D printing is reported, enabling the fabrication of complex hydrogel structures with rapid, controlled degradation and self-degradation capabilities at ambient temperature. The enhanced degradability stems from the synergistic combination of the hydrolyzable bonds and RAFT chemistry. The hydrogel precursors exhibit optimal rheological properties, while the mechanical properties of the resulting hydrogels are precisely tunable by adjusting the cross-linker content and water content. Degradation kinetics can be systematically controlled by adjusting the cross-linker content, water content, and the treatment temperature. Hydrogels containing 50 wt % water content demonstrate complete degradation into molecular chain segments and/or molecules within 6 h at 37 °C. Furthermore, the 3D printed RAFT-mediated hydrogels can self-degrade at ambient temperature. After self-degradation, the resulting solution exhibits the unsaturated acrylic functional molecules with the characteristic of high viscosity, which can be directly used for UV-assisted direct ink writing (DIW) to refabricate new 3D hydrogel structures.

Developing lead-free hybrid metal halides with stable and efficient white-light emission remains a critical challenge for next-generation optoelectronics. Here, we report a polar zinc-based organic–inorganic hybrid halide, [EMPA]2Zn3Br12 (EMPA = 5-[(4-ethylpiperazin-1-yl)methyl]pyridin-2-amine), which exhibits broadband white-light emission with a high color rendering index of 90 and high photoluminescence quantum yield of 43.9%. The material shows nonlinear optical properties with a measurable second-harmonic generation response. Unlike conventional hybrid halides, [EMPA]2Zn3Br12 demonstrates exceptional stability, retaining its structure and luminescent properties after 60 days of immersion in water and prolonged exposure to UV irradiation. Temperature-dependent photoluminescence measurements reveal that the material maintains its white-light emission from room temperature down to 260 K. Density functional theory calculations suggest that the broadband emission originates from multiple self-trapped exciton states, facilitated by Jahn–Teller distortions in the [ZnBr4]2– tetrahedra. Furthermore, a white-light-emitting diode fabricated using [EMPA]2Zn3Br12 as a single component white light emitter, demonstrating its potential for solid-state lighting. This study highlights [EMPA]2Zn3Br12 as a promising lead-free alternative for environmentally friendly high-performance white-light-emitting and optoelectronic applications.

Designing efficient photocatalysts is crucial for enhancing photocatalytic performance, with the separation efficiency of photogenerated charge carriers being a key factor, the improvement of this performance can significantly enhance antibacterial efficiency. To address the limitations of traditional bismuth oxybromide (BiOBr) photocatalysts, this study synthesized visible-light-driven Al/Cu co-doped BiOBr (2ACBB) microspheres via a solvothermal method. Dual metal doping synergistically modifies the band structure, introducing oxygen vacancies that narrow the bandgap (2.69 eV vs. 2.80 eV) while enhancing visible-light absorption and charge separation efficiency. Optimized 2ACBB exhibits a high surface area (27.64 m 2 /g) and demonstrates 3.2-fold greater photocurrent response than pristine BiOBr. EPR analysis reveals superoxide radicals ( · O 2 - ) and electrons as dominant reactive species, enabling exceptional antibacterial performance (99.99 % S. aureus and 97.99 % E. coli inactivation within 40 min). Mechanistic studies confirm that hierarchical architecture promotes bacterial adsorption and light harvesting, while generated · O 2 - and e − disrupt membrane integrity and metabolic processes. This work on the enhanced antimicrobial properties of metal ion-doped photocatalytic materials provides a perspective.
