Mn 2+ -doped perovskite nanocrystals (NCs) have attracted extensive research interest and have been synthesized with sizes in the strong confinement regime. Nevertheless, the size of the doped NCs is still not as small as that of undoped perovskite NCs. To address this, we develop a ligand-assisted reprecipitation method incorporating ultrasonication to synthesize Mn 2+ -doped CsPb(Cl/Br) 3 NCs. The obtained spherical NCs have an average size of 3.1 nm and exhibit orange photoluminescence originating from the 4 T 1 to 6 A 1 transition of Mn 2+ . The luminescent properties correlate with the volume ratio of MnCl 2 to PbBr 2 precursors. Increasing the ratio enhances the Mn 2+ -related emission, while excessive doping leads to photoluminescence quenching. When the precursor ratio is reduced to 1:1, the NCs exhibit both intrinsic exciton and Mn 2+ -related emission, with some particles adopting cubic or rod-like morphologies. Prolonged ultrasonic treatment does not significantly shift the emission peak of the NCs, but promotes superlattice assembly in small-sized NCs, showing a center-to-center separation of 4.2 nm. Subsequently, altering the precursor addition sequence to introduce MnCl 2 last during ultrasonic preparation yields simultaneous formation of spherical and cubic NCs. Finally, post-synthesis doping of Mn 2+ is achieved. Formation of small spherical NCs confirms hypothesis that MnCl 2 induces morphological transformation of NCs. Graphical Ultrasonication-assisted ligand-assisted reprecipitation delivers 3.1 nm Mn 2+ -doped CsPb(Cl/Br) 3 nanocrystals with orange emission from the Mn 2+ 4 T 1 → 6 A 1 transition.

Influenza is currently one of the most prevalent respiratory diseases in humans, with outbreaks typically occurring during the winter months. Its impact is particularly pronounced among vulnerable populations, such as the elderly, infants, and individuals with chronic illnesses. Common methods including reverse transcription polymerase chain reaction (RT-PCR), rapid influenza diagnostic tests (RIDTs), and direct fluorescent antibody (DFA) assays for detecting influenza viruses have their own limitations and struggle to meet the point-of-care testing (POCT) demands during influenza pandemics. In this study, a surface-enhanced Raman spectroscopy (SERS) sensor chip based on the immunosandwich principle was developed for the rapid detection of influenza A and B viruses. Using a portable Raman spectrometer, viral antigen detection can be completed within 20 min, with a detection limit as low as 0.69 ng/mL. This provides a new approach for the rapid screening and dynamic monitoring of influenza viruses.

A high-quality quantum dots (QDs) layer is crucial for the commercialization of quantum dot light-emitting diode (QLED) devices. However, current fabrication techniques cannot simultaneously achieve monolayer coverage, ordered arrangement, and large-area scalability. Herein, we develop a novel strategy of continuous stepwise self-assembly for QDs monolayer integrated the air-liquid interfacial assembly technology with continuous line-ink-supply and Langmuir-Schaefer (LS) technology, which the QDs can be finely to assemble into large area ordered and dense QDs monolayer film at the trailing edge of the flow. The ordered QD monolayers can be repeatedly transferred and stacked to accurately control the thickness of the luminescent layer in QLED devices. Green QLED based on this monolayer film reaches a high EQE of 23.85%. Furthermore, the optimized trilayer device exhibits negligible efficiency roll-off, retaining an EQE above 18% and a luminous efficacy of 60 lm W −1 at a luminance of 200 000 cd m −2 . This methodology also shows preliminary scalability potential. We achieved a trial fabrication of large-area QD films of 210 cm 2 and further constructed corresponding QLED devices with an emission area of 1.5 cm × 1.5 cm as an initial exploration.

Camellia oleifera oil (CO) emulsified by cationic cellulose nanofibrils. • Dual stabilization of CO via emulsion interface and gel network. • High-efficiency encapsulation and sustained release of CO by composite system. • Hydrogel retains strong antioxidant activity after 35 days of storage. In recent years, the skincare concept of nourishing skin with oils has attracted extensive attention. Camellia oleifera oil (CO) is a natural woody skincare oil with both skin barrier repair and antioxidant properties. To overcome the instability of its bioactive components, this study adopts a gel matrix composed of polyvinyl alcohol (PVA), tremella fuciformis polysaccharide (TFP) and polydopamine (PDA), loaded with CO Pickering emulsions stabilized by cationic cellulose nanofibrils (CCNF). By combining the oil-in-water emulsification method with a cyclic freeze-thaw strategy, a dual-stabilization structure of emulsion encapsulation and hydrogel network was constructed. The resultant hydrogel integrates excellent dynamic adhesion and mechanical properties, with a water holding capacity of 93.21% and a CO encapsulation efficiency of 80.38%. It enables long-term sustained release of CO for 120 h, and the release behavior follows the Fickian diffusion mechanism. It achieves DPPH and ABTS free radical scavenging ratio of 88.1% and 97.14%, respectively, with no significant attenuation of antioxidant activity during the 35 days storage period. The hydrogel also possesses favorable bacteriostatic activity and biocompatibility, with a hemolysis ratio below 5%, no skin irritation and no in vivo toxicity. This study provides a novel approach for the protection and delivery of CO as well as the green design of skincare hydrogels.

Sequential coupling of hydrophobic orientation and rapid covalent locking. • Immobilized TLL exhibits >4000% relative activity via conformational tuning. • Interfacial microenvironment regulates partitioning and methanol tolerance. • Biocatalyst demonstrates exceptional durability and efficient conversion. Efficient multiphase bioprocessing for sustainable lipid valorization and biodiesel synthesis relies on robust solid–liquid biointerfaces. Their rational design is fundamentally constrained by severe reaction–diffusion constraints and the intrinsic activity–stability trade-off. Herein, we report a synergistic “orient-and-lock” strategy on bifunctional mesoporous SBA-15 to decouple these limitations. Hydrophobic domains first drive the oriented adsorption and “lid-opening” hyperactivation of Thermomyces lanuginosus lipase, followed by rapid isocyanide-mediated covalent anchoring to kinetically trap this metastable state without compromising structural flexibility. Molecular dynamics simulations elucidate a critical microenvironmental compartmentalization effect. This spatial partitioning selectively enriches lipophilic substrates while isolating polar inhibitors through localized hydrogen-bond networks and hydrophobic compartments, thereby effectively reducing substrate transfer resistance and minimizing active site blockage. Consequently, the immobilized biocatalyst exhibits an unprecedented 40-fold enhancement in apparent specific activity and a 57-fold increase in catalytic efficiency ( k cat / K m ) compared to the free enzyme. Its excellent tolerance to methanol enables a highly efficient one-step methanol addition reaction. The system demonstrates exceptional operational robustness, retaining 80% activity over 25 consecutive cycles and achieving a 96.8% biodiesel yield, establishing a synergistic paradigm of conformational engineering and transport regulation for high-performance heterogeneous biocatalysts.

The treatment of oily wastewater demands separation materials that are efficient, durable, and resistant to harsh environments. In this work, a needle-like nanostructure (NLNS) was fabricated on a 200-mesh aluminum mesh (Base) through a two-step process combining plasma electrolytic oxidation (PEO) with hydrothermal treatment (HT). The effect of hydrothermal duration on the resulting morphology was systematically examined, identifying optimal conditions (200°C, 8 h) that yield a uniform, high-density NLNS. Unlike conventional PEO-based coatings, the sharp-tipped nanoneedle morphology maximizes capillary forces to stabilize a robust hydration layer, achieving exceptional underwater superoleophobicity with an underwater oil contact angle (UWOCA) as high as 168°. The NLNS exhibited high separation efficiency (up to 97.6%) for n-hexane/water mixtures under highly acidic, alkaline, and saline conditions, along with a stable permeation flux of ∼4900 L m −2 h −1 over 20 cycles. Durability assessments confirmed robust mechanical resistance (UWOCA > 140° after 16 friction cycles) and enhanced corrosion resistance. This strategy avoids toxic fluorinated modifiers and uses only water as the HT medium, providing a green, low-cost, and scalable route for industrial oily wastewater treatment.

In situ SiO 2 growth with DA-g-C 3 N 4 co-doping yields hybrid crosslinked PA layer. • Compound strategy mitigates DA-g-C 3 N 4 aggregation in PA layer. • Achieved simultaneous gains in Mg 2+ /Li + selectivity and permeability performance. • MgCl 2 rejection stayed >93% over 160 h, demonstrating excellent long-term stability. It is often difficult for thin-film composite (TFC) nanofiltration (NF) membranes to balance high separation selectivity and high permeability, and the contradiction between the two will lead to their overall performance constraints. In this study, a dual-phase regulation strategy is proposed, which adopts the in-situ sol method and the composite strategy of introducing two-dimensional materials for the preparation of organic-inorganic cross-linked polyamide (PA) NF membranes. A trimesoyl chloride (TMC) organic phase solution containing tetraethyl orthosilicate was first introduced onto the polyethersulfone (PES) substrate, followed by contact with a polyethyleneimine (PEI) aqueous phase solution containing dopamine-functionalized carbon nitride (DA-g-C 3 N 4 ), during which silicon dioxide (SiO 2 )/Si–O–Si domains were generated in situ within the PA layer. These domains restricted the free volume of the PA layer, narrowed the effective pore-size distribution, and suppressed nonselective defects, while the embedded DA-g-C 3 N 4 improved the compatibility between the nanofillers and the PA layer, thereby producing P-1Si-0.025CN membranes with an effective pore size of 0.4 nm. Compared with the P-NF membrane prepared by reverse interfacial polymerization of TMC and PEI directly on the PES substrate, Mg 2+ /Li + separation factor (SF) increased to 67.2 (Mg 2+ /Li + mass ratio is 20), salt solution flux was 27.1 LMH, separation and permeation capacity of mixed salt was enhanced, salt solution flux has increased by 4 times, and the SF has increased by 7 times, Mg 2+ /Li + ratio decreased from 20 in feed to 0.71 in permeation process. Moreover, it exhibited excellent separation performance in diluted salt lake brine, with an Mg 2+ rejection rate exceeding 98%, and it also exhibited high fouling resistance and long-term stability.

We develop a novel cyclic alternating deposition strategy to fabricate a breathable and robust superhydrophobic membrane. • The membrane exhibits a water contact angle of 156.4 ± 1.7°, excellent self-cleaning and anti-icing properties. • The membrane demonstrates ultrahigh separation efficiency (98.4%) and outstanding absorption capacity (53.5 g/g). • The membrane maintains a contact angle above 153° after 50 friction cycles. Artificial superhydrophobic membranes show great promise for oily wastewater treatment and oil spill remediation, yet they often face a fundamental trade-off between liquid repellency and vapor permeability, with dense structures sacrificing breathability and ultimately leading to performance degradation under prolonged use. Therefore, integrating persistent superhydrophobicity with high breathability and mechanical durability remains challenging. Inspired by the hierarchical microarchitecture of Hygroryza aristata , this study develops a novel cyclic alternating deposition strategy that combines electrospinning and electrospraying to fabricate a breathable, flexible, and robust superhydrophobic membrane with a hierarchical fiber-sphere alternating structure (HFBA). It exhibits a water contact angle of 156.4 ± 1.7°, excellent self-cleaning and anti-icing properties, and satisfactory mechanical performance. It also demonstrates favorable breathability, with a steady-state water vapor transmission rate of 184.38 g·m −2 ·d −1 and a gas permeability of 2725.18 cc·m −2 ·d −1 , effectively reconciling the liquid-repellency/breathability trade-off. Moreover, it demonstrates ultrahigh separation efficiency (98.4%) and outstanding absorption capacity (53.5 g/g) for various oil–water mixtures. The membrane maintains a contact angle above 153° after 50 friction cycles and shows negligible efficiency loss (<1%) over 10 separation cycles, highlighting exceptional durability. This work provides a robust biomimetic material with significant potential for practical oil-polluted water treatment and marine environmental protection.

This work presents a novel flexible imprinted membrane-made surface-enhanced Raman scattering (SERS) for selective detection of microcystins-LR (MC-LR) in water. Silver nanocubes decorated with titanium dioxide (Ag NCs@TiO 2 ) nanoparticles (NPs) are dispersed on a flexible polydimethylsiloxane (PDMS) membrane as the SERS substrate. The PDMS exhibits excellent optical properties, ensuring the detection accuracy. A photo-initiated polymerization process is employed to maintain the molecular integrity of MC-LR while improving the resistance of the SERS substrates to air-induced oxidation. By optimizing the reaction condition, optimal SERS imprinted membrane is applied to selective detection of practical samples. The characterization results indicate that the Ag NCs@TiO 2 molecular imprinted membranes (ATP-MIMs) present accurate detection property to the MC-LR molecules from complex solution. Rapid detection within around 1 min is achieved by the as-prepared flexible molecularly imprinted SERS sensor. The limit of detection of MC-LR is 0.0313 μg·L −1 and the ATP-MIMs exhibit a high stability of more than 86.6 % after 28 days. It clearly exhibits from results that ATP-MIMs hold significant potential applications to trace MC-LR detection and provide a novel approach to the water quality monitoring.

Motivated by gas-accessible thin liquid films in lung alveoli, we develop gas marble-film reactors in which particle-stabilized bubbles confine an ultrathin freestanding liquid film within a jammed solid shell. Hexagonal PET (poly(ethylene terephthalate)) plates, in addition to conventional spherical particles, generate faceted gas marbles with planar film regions that improve optical access. We quantify the pressure limits of microsphere- and plate-stabilized shells during inflation and deflation, and describe their response using a capillary–granular framework. In this framework, inflation rupture is governed by capillary breakthrough at particle-defined throats, whereas deflation collapse reflects the combined resistance of capillarity and interparticle jamming. The mechanically defined films then serve as gas-accessible interfacial reactors in two proof-of-concept demonstrations. In a Tollens reaction, aerosolized glucose delivery through the external gas phase localizes silver reduction to liquid-wetted regions of the particle shell, producing spatially patterned silver-deposited microspheres. In biological assays, plate-stabilized shells provide flat observation windows for monitoring aerobic E. coli growth and its inhibition by levofloxacin. These results establish gas marbles as programmable colloidal film reactors whose structure, pressure stability, and interfacial function can be coupled through particle geometry and capillary jamming.

New Delhi metallo-β-lactamase (NDM)-producing drug-resistant bacteria often form stubborn biofilms and cause severe pneumonia, resulting in conventional antibiotic failure. In this study, we developed gelatin-genipin microspheres co-loaded with EDTA and meropenem (GEM) for targeted treatment of NDM pneumonia. EDTA exerted dual functions: it chelated Zn 2+ to inactivate NDM enzyme and restore meropenem activity (FIC = 0.046875), while also disrupting bacterial biofilms through chelation. GEM microspheres enable accelerated drug release in the artificial phlegm environment. In a mouse model of NDM pneumonia, GEM microspheres can enhance the recruitment of neutrophils and M1 cells at the early stage (12 h) through bacterial clearance, modulate the secretion of interferon-γ by CD8 + T cells and natural killer cells, and reshape the pulmonary immune microenvironment. Furthermore, GEM treatment reduced pathological pulmonary immune cell infiltration and excessive inflammation at late time points (days 3-7). Taken together, GEM microspheres integrate biofilm disruption, enzyme inhibition, synergistic bactericidal effects, and immunoregulation, representing a promising strategy against NDM drug-resistant bacterial pneumonia.

Lipid oxidation governs myricetin degradation in heated palmitic acid. • o-Quinone formation triggers B-ring cleavage and oxidative dimerization. • Carbonyl addition and lipid-derived ester conjugates were detected. • Vitamin C suppresses radical-driven pathways and improves myricetin retention. Dietary polyphenols are susceptible to degradation during high-temperature cooking, yet their transformation behavior in lipid-rich frying systems remains poorly understood. The thermal stability and degradation of myricetin in a simplified palmitic acid model under frying-relevant conditions was investigated. Myricetin degraded rapidly at 180 °C but remained relatively stable at 120 °C. UPLC–QTOF–MS/MS, supported by density functional theory calculations, suggested that myricetin transformation is temperature-dependent but primarily governed by lipid oxidation–derived radical and carbonyl chemistry. Vitamin C markedly delayed myricetin degradation by suppressing radical initiation and limiting o -quinone–centered downstream reactions. These findings highlight lipid oxidation as a key determinant of polyphenol stability during frying and clarify the protective role of antioxidants in lipid-rich thermal processing systems.
