Colloidal quantum dots (QDs) are promising optical gain materials that require a reduction in the threshold to reach their full potential. While QD charging theoretically reduces the threshold to zero, its effectiveness has been limited by strong Auger recombination and unstable charging. In this study, we theoretically determine the optimal combination of charging number and Auger recombination to minimize the lasing threshold. Experimentally, we develop stable, self-charged perovskite quantum rods (QRs) as an alternative to QDs via the state engineering and Mn (manganese) doping strategy. A two-order-of-magnitude reduction in nonradiative Auger recombination enables QRs to support a charging number of up to 6. We then achieve QR liquid lasing with a sub- 1 / 10 exciton threshold (an average of 0.098 excitons per QR) using 5-nanosecond pulse pumping. This threshold is exceptionally low among all reported QD lasers. These achievements demonstrate the potential of specially engineered QRs as excellent gain media and pave the way for their applications.

A bio-inspired monolithic design mimicking plant lignification and lotus effect achieves holistic protection. • A paradigm shift from polymers to inorganic ASF fibers enables unprecedented environmental robustness. • Synergistic dual-functionality integration of high-sensitivity strain sensing and high-flux oil-water separation. • Superhydrophobic surface enables separation and providing a self-cleaning, protective barrier for embedded sensor. Flexible electronics and membrane technologies face a fundamental challenge in harsh environments: the inherent instability of polymeric materials under thermal, chemical, and mechanical stresses. Here, we break away from conventional polymer-based designs and report a monolithic, bio-inspired multifunctional platform based on an aluminum silicate fiber (ASF) scaffold. By mimicking the holistic reinforcement of plant lignification and the persistent self-cleaning of lotus leaves, we construct a superhydrophobic conductive membrane through a rational layer-by-layer assembly. Hydroxyapatite nanowires (HAPNWs) enhance interfacial adhesion, graphene (Gr) forms a strain-sensitive three-dimensional network, and a dual-layer composite composed of polydimethylsiloxane/SiO 2 (PDMS/SiO 2 ) and 1H, 1H, 2H, 2H-perfluorodecyltriethoxysilane/SiO 2 (PFDTMS/SiO 2 ) provides both bulk encapsulation and surface superhydrophobicity. This biomimetic design uniquely integrates two seemingly disparate functions into a single material: high-performance strain sensing and efficient oil-water separation. The ASF@HAPNW/Gr@PDMS-SiO 2 @PFDTMS-SiO 2 superhydrophobic conductive membrane (SHCM) exhibits outstanding sensing capabilities with a high gauge factor (GF) of 106.6, fast response/recovery (290/270 ms), and robust cyclic durability (>4000 bends). Simultaneously, it serves as a gravity-driven separation membrane with a flux exceeding 10,000 L·m −2 ·h −1 and efficiency >95% for various oils. More importantly, the inorganic–organic hybrid architecture endows the SHCM with unprecedented environmental robustness. The membrane maintains its superhydrophobicity and functional performance after exposure to 500 °C, a wide pH range (3−11), prolonged UV irradiation, and mechanical abrasion—conditions that rapidly degrade conventional polymer-based devices. This work establishes a new material design paradigm that bridges flexible sensing and environmental remediation, offering a reliable, multifunctional solution for extreme and complex scenarios.

UFA molecular geometry directs hierarchical assembly of starch-lipid systems. • US-DHPM induces UFA-templated starch reassembly from helices to aggregates. • C18 UFAs promote ordered lamellar barriers and enhanced digestion resistance. • Long-chain PUFAs generate strain-induced heterogeneity and rapid digestion. • Digestive resistance is governed by barrier continuity rather than CI alone. The influence of unsaturated fatty acid molecular geometry on the assembly and digestive properties of starch-lipid complexes remains unclear. Here, five UFAs with distinct chain lengths and configurations were incorporated into gelatinized wheat starch via ultrasound-assisted dynamic high-pressure microfluidization to construct hierarchical complexes. Multiscale analyses showed that UFA geometry governed amylose helix inclusion, V-type crystallinity, and lamellar packing. Monounsaturated UFAs promoted compact ordered assemblies, whereas highly unsaturated UFAs generated looser interfacial structures. These differences were reflected in digestion behavior, with oleic-acid-based complexes exhibiting enhanced digestion resistance and delayed lipid release, while certain highly unsaturated systems such as DHA showed accelerated starch hydrolysis and fatty acid liberation. Notably the linoleic acid-based complex exhibited the highest resistant starch content of 20.77% and the slowest fatty acid release with 29.70% of fatty acids still retained after 120 min of digestion. Correlation analysis and molecular dynamics simulations further indicated that digestive resistance depends on the continuity of hierarchical packing rather than complexation efficiency alone. These findings clarify geometry-dependent structure-digestion relationships in starch-lipid complexes and support structure-guided design of systems with tunable digestive properties.

Fire safety remains a critical global challenge, as conventional fire protective materials focus on passive insulation/flame retardancy but lack active early-warning for incipient fires. Chitosan (CS)-based foams are promising for fire protection but suffer from inherent flammability, limiting practical use. Herein, CS-based foams composited with hydroxyapatite nanowires (HAP NWs) and phytate-melamine (PA/MEL) were fabricated via freeze-drying, forming an “active warning-passive protection” system. Structural characterizations confirmed uniform dispersion of HAP NWs and PA/MEL in CS matrix via hydrogen/ionic bonding. Thermogravimetric analysis revealed CS-HAP-10PA/MEL had 61.6% char residue at 750 °C (N 2 ), a 105.3% increase vs. pure CS. CS-HAP-10PA/MEL exhibited a limiting oxygen index (LOI) of 45.0% and a 76.3% lower peak heat release rate (pHRR) than pure CS, manifesting excellent flame retardancy. Fire warning tests indicated that CS-HAP-5PA/MEL triggered an alarm within 4.2 s (signal stable >60 s) upon exposure to flame and exhibited sensitive responsiveness at 60–200 °C (0.8 s response at 120 °C). A 6 mm-thick CS-HAP-5PA/MEL (36.6 mW/ (m . K)) sample reached only 61 °C surface temperature after 5 min at 120 °C (14.2 °C lower than pure CS), demonstrating good thermal insulation. This foam integrates warning, flame retardancy, and insulation, offering a novel strategy for intelligent fire protective materials.

Gynecological tumors pose a serious risk to female health, and traditional therapies have many limitations. Here, we developed a near-infrared light-triggered nanoplatform (UCNPs@SiO₂-MB@PDA) for synergistic photodynamic therapy (PDT) and photothermal therapy (PTT) of deep tumors. The nanoplatform takes the UCNPs as the core, wraps the silica shell loaded with the photosensitizer MB via the inverse microemulsion method, and finally modifies the surface of the PDA. Under 980 nm excitation, the red light emitted by the UCNPs can effectively activate MB to produce singlet oxygen through luminescence resonance energy transfer, achieving PDT. At the same time, the PDA shell can efficiently absorb the multiband emitted light of the UCNPs and convert it into thermal energy, achieving PTT with a photothermal conversion efficiency of 35.6%. In vitro cell experiments have shown that the material has good biocompatibility and can be effectively internalized by tumor cells. Under near-infrared light irradiation, its killing effect on HeLa cells was considerably better than that of monotherapy, and the cell survival rate decreased to 18.9% when the cells were exposed to a concentration of 200 μg/mL. The results of the live/dead cell staining further confirmed the excellent synergistic antitumor performance of these materials. This work offers a promising strategy for the precise and effective treatment of deep tumors.

A novel hydrophobic deep eutectic solvent (HDES) composed of menthol and lactic acid was successfully synthesized and applied for the simultaneous vortex-assisted liquid–liquid microextraction (VA-LLME) of triterpenoids (glycyrrhizic acid, GL, and glycyrrhetinic acid, GA) and a flavonoid (chalcone A, ChA) from licorice extract. Under the optimized conditions using 5 mL of plant extract and 800 μL of HDES, the target analytes were efficiently extracted via vortex mixing and centrifugation, with the resulting HDES phase directly analyzed by high-performance capillary electrophoresis (HPCE). The proposed method demonstrated excellent linearity (3–600 μg/mL, R² > 0.9954) for all analytes. The limits of detection (LODs) and quantification (LOQs) ranged from 0.67 to 2.97 μg/mL and 2.22 to 9.90 μg/mL, respectively. Intra-day and inter-day precision (RSD) were below 4.21% and 6.41%, with recoveries between 91.51% and 105.1%. The method is relatively sensitive, showing particularly good enrichment for GL and GA in licorice, and can be applied to the purification of triterpenoids from this herb. Overall, this approach is simple, rapid, environmentally friendly, and has been successfully applied to the accurate quantification of triterpenoids and flavonoids in licorice extract.

Thiamethoxam (THI), a widely used neonicotinoid pesticide, is of crucial significance for the accurate detection of THI in terms of environmental and food safety. In this study, a portable fluorescent aptasensor was developed for the rapid and sensitive detection of thiamethoxam (THI). Based on the principle of fluorescence resonance energy transfer (FRET), the sensor system consists of THI-specific aptamers (UCNPs-apt) and upconversion nanoparticles (UCNPs) functionalized with graphene oxide (GO). Compared to conventional fluorophores, UCNPs exhibit minimal background fluorescence, thereby minimizing interference in complex matrices such as food samples. Key parameters, including GO concentration (0.15 mg/mL), UCNPs/GO incubation time (40 min), pH (7.4), and THI reaction time (30 min), were optimized to maximize fluorescence quenching and target-induced recovery. The sensor showed a linear detection range of 0.1–100 ng/mL and a limit of detection (LOD) of 0.088 ng/mL, with excellent selectivity and reproducibility. The method was validated using peach and mulberry leaf samples, yielding results consistent with ELISA (recoveries: 98.79–113.04%; relative standard deviations: 0.46–1.92%). The integrated portable system, leveraging aptamer specificity and compact instrumentation, enables on-site monitoring and addresses the urgent need for rapid field-deployable detection of THI residues.

Infrared (IR)-to-visible upconversion devices integrate IR photodetection and visible light emission into a single device. Such devices selectively emit visible photons from regions irradiated by IR photons, enabling simplified and low-cost pixel-less imaging. Recently, the integration of colloidal quantum dots (CQDs)-based IR photodetection units with organic semiconductor–based visible emitters has attracted significant attention. These quantum dot organic upconversion devices (QOUDs) benefit from solution processability and tunable infrared absorption. However, their performance has so far been limited by inefficient coupling between the absorption and emission units as well as the relatively low efficiency of the photodetection layer. In this work, a high-performance QOUD is demonstrated by incorporating an improved interconnection layer (ICL) and introducing a photomultiplication (PM) mechanism. A photon-to-photon efficiency of 23% is achieved, which is 143 times higher than that of a gain-free device. The low-barrier interconnection is achieved by using an ultrathin MoO3 ICL, which provides favorable energy level alignment. The turn-on voltage of the QOUD under infrared illumination was greatly reduced to 1.9 V. In addition, the PM effect originates from the absorption layer, where defect states trap photogenerated carriers and induce image-charge-assisted carrier injection from the electrode. The QOUD is further demonstrated for pixel-less IR imaging, combining low turn-on voltage with high PM and showing strong potential for practical infrared imaging applications.

Efficient and recyclable piezoelectric polymers are promising materials for environmental purification and energy regeneration. In addition to the most widely studied polyvinylidene fluoride (PVDF), chiral poly-L-actic acid is an attractive biodegradable alternative that also exhibits piezoelectricity when highly oriented and polarized through electrospinning. In this work, highly-oriented electrospun fibers of poly-L-lactic acid (PLLA) doped with the dopamine-modified barium titanate (HBTO) are fabricated and subsequent hydrophilic modification yields a piezocatalytic membrane (HBTO@HPLLA) rich in catalytic active sites. The interfacial interaction between HBTO and PLLA is enhanced via hydrogen bonding, significantly improving the piezoelectric activities of the resulting composite membrane. Consequently, HBTO@HPLLA degrades Bisphenol A (BPA) in water under ultrasonic vibration at a rate constant 4.3 times higher than pure PLLA. Furthermore, when adhered to the blades of a propeller with mechanical stirring at 1200 rpm, the HBTO@HPLLA membrane also demonstrates high efficiency in BPA removal. This approach offers a promising strategy for developing biocompatible piezoelectric materials utilizing natural low-frequency mechanical energy for environmental remediation.

The efficient electrocatalytic oxidation of glycerol (GLY) is one of the most promising routes for the valorization of GLY. Doping has emerged as a powerful strategy to tailor the electrocatalytic performance of silver nanoclusters (Ag NCs), yet the effects of doping mode (surface vs. core) and the interface environment (e.g., electrolyte concentration) on the electrocatalytic performance for Ag NCs toward GLY oxidation remain understood. In this work, surface-doped Ag 4 M 2 (SR) 8 and core-doped Ag 24 M(SR) 18 (M = Ni, Pd, Pt; SR = SPhMe 2 ) NCs were synthesized for electrocatalytic GLY oxidation. The results revealed a strong dependence of selectivity on doping mode and electrolyte concentration: under low KOH concentration, Pd- and Pt-doped Ag 4 M 2 NCs exhibited 100% selectivity toward oxalic acid (OA), whereas Pd- and Pt-doped Ag 24 M NCs delivered >95% selectivity for formic acid (FA). In contrast, under high KOH concentration, Pd- and Pt-doped Ag 4 M 2 NCs gave rise to >80% FA, while Pd- and Pt-doped Ag 24 M NCs produced >45% FA. Mechanism studies indicated that Ni doping predominantly enhanced catalytic activity via lowering the activation barrier of the initial reaction step (GLY→glyceraldehyde), whereas Pd and Pt doping modulated selectivity through reducing the energy barrier of the selective branch step (glyceric acid→OA, OA→FA). High KOH concentration promoted the oxidation by increasing the electrochemical active surface area and facilitating electron transfer of Ag NCs. This study provides clear guidance for designing high-performance Ag-based electrocatalysts for biomass valorization.

Upconversion luminescence (UCL) materials exhibit significant potential for applications in biological imaging, solar cells, and optical security. However, their efficiency is constrained by the low absorption cross-sections and nonradiative energy losses intrinsic to rare earth ions. In this study, remarkable UCL enhancement was achieved for Cs 2 NaYCl 6 : Yb 3+ /Tm 3+ core–shell nanoparticles (csUCNPs) via surface passivation and the local surface plasmon resonance (LSPR) effect. At a high Tm 3+ doping concentration (10%), the system exhibits the highest fluorescence intensity, surpassing the low-doping limits reported in conventional systems with larger lattice parameters. This marks the first report of intense fluorescence induced by high-concentration Tm 3+ doping in this system. Surface defects and non-radiative transitions were further suppressed via a dual strategy of double perovskite coating and SiO 2 encapsulation, simultaneously enhancing both material stability and luminescence efficiency. Furthermore, the LSPR effect of Cs x WO 3 significantly enhanced the UCL efficiency of csUCNPs, with luminescence intensity amplified by approximately twofold through the synergistic interplay of localized electromagnetic field enhancement and energy transfer, providing experimental and theoretical insights into the role of semiconductor LSPR effects in rare earth luminescence. This work demonstrates further promising potential in multicolor anti-counterfeiting applications for advanced encryption technologies and cell imaging for biological detection.

Optically switchable functions are highly interesting for AI applications in smart displays, memory encryption, and neuromorphic computing. The use of molecular photoswitches to precisely modulate functionalities at the nanoscale, such as photoluminescence (PL), is essential for developing photoswitchable nanomaterials. However, it is challenging to achieve the universal regulation of full-color PL, particularly for the efficient optical modulation while maintaining both high PL quantum yield (PLQY) and effective photoswitchable states. Herein, we report a simple and efficient photoswitchable system achieved through the hybridization of quantum dots (QDs) and diarylethene (DAE) photoswitches. The PL intensity of the three primary colors (RGB) can be reversibly switched on and off using the same DAE upon exposure to specific light. Our design exhibits a maximum PLQY exceeding 90% in the on state while maintaining a PL on/off ratio approaching 100, which represents one of the current highest values. The excellent performance relies on the synergistic energy transfer mechanism of the Förster resonance energy transfer and triplet energy transfer. Our photoswitchable materials enable the straightforward preparation of RGB QDs@DAE films for applications in reversible patterned display and information encryption. The patterns and information can be erased and rewritten multiple times, offering flexible and reusable smart materials toward data storage, advanced display, and anti-counterfeiting technologies.
