The Fenton-like application potential of MoS2 has recently attracted widespread interest in advanced oxidation processes. This study utilized natural molybdenite ore as the source of MoS2, and the Fenton-like reactivity of molybdenite was further enhanced by dropping Fe(III) ions on the basal planes of MoS2. EDS elemental analysis and XPS results suggest that Fe species were successfully anchored on the molybdenite surface, which exhibited exceptional efficiency in peracetic acid (PAA) activation. The Fe-molybdenite/PAA system achieved 83.2% degradation of sulfamethazine (SMT) within 30 min, and the reaction efficiency by Fe-molybdenite was 3.3 times higher than that of the unmodified molybdenite. HO• and Fe(V) were identified as the reactive species (RSs) during PAA activation, and SMT was degraded by these RSs. Increasing Fe-molybdenite and PAA dosages enhanced SMT degradation, with optimal performance observed at pH 4. Hydroxylation, nitrification, Smiles rearrangement and radical recombination reactions were involved during SMT degradation. Tetracyclines, dyes and other sulphonamide antibiotics could also be well degraded by Fe-molybdenite/PAA. This study elucidates fundamental design principles for engineering Fenton-like catalysts from natural mineral precursors.

The conversion of CO2/H2O into valuable chemicals with nonthermal plasma (NTP) under mild conditions represents a promising strategy, whereas the quenching effect and side reactions caused by H2O seriously restrict its efficiency. Herein, we propose a surface microenvironment modulation strategy by confining phosphomolybdic acid (PMA) within UiO-66 to construct a highly hydrophilic PMA/UiO-66 catalyst for plasma-catalytic CO2 conversion in a dielectric barrier discharge system. Theoretical calculations and experimental results confirm that the abundant exposed oxygen atoms in PMA/UiO-66 can form a hydrogen-bonding network with H2O molecule, which effectively promotes the enrichment and activation of H2O on the catalyst surface and suppresses the quenching effect of bulk H2O molecules on the plasma-induced dissociation of CO2. Meanwhile, the hydrogen-bonding network acts as an electron-trapping center and proton transport channel, lowering the free energy barrier for CO2-to-*COOH step, thereby accelerating the reaction kinetics of CO2 conversion. Under optimal energy efficiency conditions for NTP-catalyzed CO2 conversion, the PMA/UiO-66 system achieves a CO2 conversion of 17.78%, which is approximately 5 times greater than that of the plasma-only system. The study on the regulation of the catalyst surface microenvironment offers valuable insights for designing high-performance catalysts for plasma-catalytic CO2 conversion.

Background: Total glycosides of peony (TGP) have therapeutic potential for immune-related and inflammatory skin diseases, but their skin absorption is not satisfactory. This study aims to investigate howEvodia rutaecarpavolatile oil (VO-ER) enhances the permeability of TGP.Methods: Safety assessment was conducted through cell delivery and skin erythema tests. The chemical composition of VO-ER was identified via GC-MS. The study was conducted using modified Franz diffusion cells, microdialysis, confocal laser scanning microscopy (CLSM), attenuated total reflection–Fourier transform infrared spectroscopy (ATR-FTIR), molecular docking and molecular dynamics simulations (MD), laser Doppler flowmetry (LDF), and the western blotting method.Results: The study found that VO-ER promotes the permeation of total glycosides of peony in a concentration-dependent manner by disrupting the intercellular lipid tissue structure, downregulating the expression of claudin-1, claudin-7, and occludin, and improving local microcirculation, thereby promoting the absorption of TGP.Conclusions: VO-ER enhances the transdermal absorption of TGP through multiple mechanisms, such as disrupting the skin lipid barrier, downregulating tight junction proteins, and improving local skin microcirculation. This study provides a theoretical basis for VO-ER as a safe and effective new transdermal penetration enhancer, offering support for the development of topical preparations containingEvodia rutaecarpaandPaeonia lactiflora.

Pu’er raw tea, a representative tea with a positive correlation between quality and storage time, has a unique aging process. It can not only reduce the heavy astringent taste of newly produced tea, but also has a complex and fragrant aging aroma. However, the extremely slow natural aging process often takes years or even decades for quality transformation, along with the risk of termite infestation, odor absorption, etc. This study found that UV-C irradiation could significantly accelerate the aging process of tea. It enhanced the richness of the aroma, while reducing astringency and creating a smoother and mellower taste. The results of substances analysis revealed an increase in key aroma compounds such as alcohols, aldehydes and terpenes, and a decrease in catechin and caffeine with UV-C irradiation, which is consistent with the natural aging trend. An efficient and safe rapid aging technology of Pu’er raw tea has been successfully established.

Traditional scintillators rely on rigid inorganic matrices with high- Z elements, whose mechanical inflexibility restricts applications in multiple scenarios. Developing an efficient scintillator that combines inorganic properties with flexibility is a desirable yet highly challenging goal. We pioneered an inorganic metafabric scintillator paradigm through self-sustained slip system engineering, transforming brittle all-inorganic scintillation materials into ductile textile architectures, yielding intrinsically conformally flexible scintillators that adhere seamlessly to complex, curved surfaces. The ultimate all-inorganic scintillator delivers near-unity quantum yield, with scintillation output more than 10 times higher than that of previous polymer matrix–based flexible scintillators. Using these metafabric scintillators, a multimodal x-ray interactive wearable platform (X-Wear) was developed, and their applications in body-centered flexible detection and imaging, mobile health, visual radiation monitoring, and breathable radiation shielding were successfully demonstrated. This work offers a previously undefined paradigm for a scintillator system design strategy that maintains the high performance of inorganic scintillators while adding the functionality of being conformally flexible and wearable of fabrics.

Dynamic manipulation of terahertz waves is crucial for advancing rapidly evolving terahertz technologies. Recently, intercalation in 2D materials has emerged as a powerful strategy for tuning their physical and chemical properties, enhancing their potential for terahertz modulation applications. However, the terahertz-band response during intercalation and the underlying optical response mechanisms remain poorly understood. Herein, the tunable terahertz properties of the reduced graphene oxide films are investigated via ionic liquid intercalation and elucidate the associated terahertz response mechanism. The free charge carriers transport characteristics during the intercalation process are extracted using Drude–Smith model. The mechanism behind the terahertz response primarily stems from the intercalation of ionic liquid into the reduced graphene oxide films, resulting in an increase in the number of free carriers responding to terahertz waves. These results provide valuable insights for graphene-based tunable terahertz wave control and open a route toward exploring the intercalation mechanism in 2D materials.

Developing Pt-based core–shell catalysts with ultralow Pt loading, superior performance, and extended durability holds tremendous potential for advancing electrochemical energy storage and conversion technologies. However, current synthetic limitations persist in achieving atomically efficient Pt monolayer deposition on nonprecious metal substrates, hindering the maximization of Pt atomic utilization for cost-effective catalyst design. Here, we demonstrate a galvanic replacement strategy to synthesize tensile-strained platinum single-atom-layer (Pt SAL) on α-MoC substrates. The Pt SAL catalysts enable cooperative catalysis between adjacent Pt sites while maintaining nearly 100% atomic utilization efficiency. For alkaline hydrogen evolution, the Pt SAL/α-MoC catalyst exhibits optimized reaction energetics, reducing activation barriers for water dissociation, hydrogen adsorption, and H2 desorption compared to typical Pt/C. As a result, the Pt SAL catalysts exhibit superior hydrogen evolution reaction (HER) performance, with a mass activity of 1.71 A mgPt–1 at an overpotential of 50 mV, surpassing commercial Pt/C by 6.35-fold and single-atom catalysts by 7.68-fold. Remarkably, the Pt SAL catalysts reveal negligible activity decay after 10,000 cycles, with density functional theory (DFT) calculations attributing this stability to strong Pt–Mo interfacial bonding. In situ Raman spectroscopic studies reveal dynamic interfacial water restructuring that accelerates reaction kinetics. This work establishes a versatile synthesis approach for noble metal SAL catalysts and explores their role in designing high-performance electrocatalysts for heterogeneous catalysis.

MXenes have emerged as a highly promising material for next-generation patterned flexible sensing devices owing to their exceptional electrical conductivity, biosafety, and processability. In this study, we present a facile polyelectrolyte-assisted aerosol jet printing (AJP) strategy for fabricating MXene-based flexible sensors with largely improved printing quality for the applications in humidity and temperature sensing. By leveraging the electrostatic interactions network between sodium alginate (SA)-modified MXene ink and a chitosan (CS) substrate, the sensor achieves densely and stably packed MXene nanosheets with minimized defects. The intercalated SA molecules not only improve printing quality of AJP, but also enhance the humidity and temperature sensitivity of the MXene/SA patterns by modulating the interlayer spacing and functional groups within MXene layers. The resulting MXene/SA@CS sensor achieves a temperature coefficient of resistance (TCR) of 1.08% °C −1 (30–110 °C) and exhibits real-time responses to humidity changes from human motions with the largest 356 ± 9% resistance response rate and the shortest rapid response/recovery times (0.30 s/2.00 s). Its excellent antimicrobial properties and biocompatibility highlight the potential for wearable health monitoring and human-machine interfaces. Finally, the AJP-printed MXene sensors with programmable structures were successfully applied as a noncontact controller via finger movement detection.

The size dependence of metal nanoparticles is a critical factor affecting catalytic activity, as their geometric and electronic properties vary significantly with size. This study proposes a strategy combining rapid Joule-heating with solid-phase synthesis to prepare Cr/Sn-Beta bimetallic catalysts of various sizes via ultrafast thermal shock (UTS, heating rate: 1850 °C/s) and conventional muffle furnace annealing (MFA, heating rate: 5 °C/min). HRTEM results reveal that the bimetallic particle size of Cr/Sn-Beta catalysts prepared via UTS technique is only 2.55 nm, compared to 6.54 nm for catalysts obtained through conventional MFA method. Combined with XRD, BET, H 2 -TPR, UV–vis and FT-IR characterization, it is further confirmed that the ultra-high heating/cooling rate and second-short heating duration of the UTS method achieved efficient embedding of Cr and Sn within the zeolite micropores, which conferred precise tailoring of the particle size. The correlation between particle size and catalytic activity was investigated using the LA production from cellulose as a model reaction. In this work, the superior size effect of bimetallics nanoparticles prepared by UTS synthesis strategies was emphasized, providing insights into the geometry-activity relationship that will guide the rational design of catalysts in terms of morphology and particle size.

The introduction of noble metal nanoparticles effectively improves the photocatalytic performance of TiO2 due to the retarded recombination time of the photo-generated electron-hole pairs as well as raised charge transfer rate at interfaces within the composites. In this study, spherical TiO2 particles were prepared by sol-gel reaction and converted into anatase phase by calcination treatment. Ag nanoparticles were deposited on the spherical TiO2, yielding an optoplasmonic core-satellite composite structure. The coverage of Ag nanoparticles on the TiO2 surface was tuned by altering the duration of electroless plating. Due to the enhanced interaction between metal nanoparticle and dielectric component, the photodegradation of organic dyes was promoted accordingly. It was found that with proper Ag deposition degree, the optoplasmonic particle demonstrates the improved photocatalytic performance under ultraviolet and visible excitation. This composite particle was further evaluated in the experiments of practical copper electroplating solution, in which the optoplasmonic particles exhibit promoted photocatalytic activity. This developed structure is therefore a powerful candidate for the low-cost removal of organic additives.

Solvatochromic luminescent materials that can change their luminescence color upon solvent treatment have attracted considerable attention owing to their frontier applications in sensing and information encryption technologies. However, existing solvatochromic luminescent materials typically suffer from a slow response rate, limited color tunability, insufficient luminescence efficiency, and complicated synthesis process. Herein, a facile solvent-assisted and solubility-driven powder-to-powder strategy is developed for quick and mass synthesis of solvatochromic luminescent organic–inorganic manganese(II)-based halide microcrystals. The as-synthesized 0D green-emissive (TMA) 2 MnCl 4 (TMA: tetramethylammonium) and 1D red-emissive (TMA)MnCl 3 microcrystals can be reversibly converted into each other upon contact with different solvents. The solvent-induced phase transformations are accompanied by the strip of TMACl or MnCl 2 components, leading to the change of the coordination number of Mn 2+ and therefore the crystal field strength. Correspondingly, the emission color realizes a reversible switching between green and red. Notably, the phase transformation exhibits high selectivity toward solvents, and a fast response time in just 0.9 s from (TMA) 2 MnCl 4 to (TMA)MnCl 3 . The advances in these solvatochromic luminescent materials provide exciting opportunities for constructing a series of multicolor anti-counterfeiting and information encryption patterns. This work provides new insights for solvatochromic material design and promotes advanced encryption development.

The migration and accumulation mechanisms of trace elements (As, Pb, Cr, Cu, Ni, Zn, Mn) from coal fly ash in soil-plant systems critically constrain its sustainable utilization. Through integrated approaches including sequential chemical extraction, leaching experiments, electron probe microanalysis, and meta-analysis of bioconcentration data, this study reveals ash-type-dependent element levels with migration capacity: Mn > As > Zn > Cu > Ni > Cr > Pb, governed by their chemical speciation and mineral associations. Elements were classified into three activity groups based on activity and effective mass percentages, aligned with RAC risk levels. Divergent risk evaluations emerged: Nemerow index and ecological risk index indicated moderate pollution (Pz = 2.76) and slight risk (RI = 64.25) based on total content, highlighting differing RAC evaluation outcomes considering speciation. Meta-analysis of a robust bias-tested dataset demonstrated ash generally elevates trace elements in rice but not corn/wheat, with root accumulation exceeding shoots and application rates > 10–20 % significantly increasing concentrations. Crucially, by comparison between predicted values from pollution indices that based speciation concentrations and empirically measured elemental bioconcentration data, residual fractions (F3/F4/F5) positively correlated with plant bioaccumulation, whereas bioavailable fractions (F1/F2) dominated ecological hazards. These findings provide: (1) a speciation-based framework for environmental risk assessment prioritizing F1/F2, and (2) phytoremediation strategies targeting F3/F4/F5, enabling balanced coal ash reuse and risk mitigation through differentiated management of chemical fractions.
