In-situ photo-patterning of ZnO was successfully achieved at room temperature. • QLEDs utilizing photolithographic ZnO as the ETL demonstrated superior performance. • The positive-aging effect was significantly alleviated by using photolithographic ZnO. • ZnO patterns were utilized to construct carrier transport channels in pixelated QLEDs. Benefiting from the adjustable emission spectrum, high color purity, wide gamut, and solution-processability, quantum dot light-emitting diode (QLED) is considered one of the most promising next-generation display technologies. As a prevalent electron transport material, ZnO plays a crucial role in enhancing the efficiency and long-term stability of QLED devices. To promote the development of high-resolution QLED displays, this study proposes a dual-functional surface engineering strategy for achieving in-situ photo-patternable ZnO with enhanced electrical properties. Physicochemical characterization revealed that surface defects of ZnO were significantly reduced via direct photolithography, thereby decreasing non-radiative exciton recombination at the QD/ZnO interface. Particularly, the red QLED devices based on photolithographic ZnO exhibited remarkable performance, achieving a peak external quantum efficiency (EQE) of 23.5%, a brightness of over 140,000 cd m −2 at 5 V, and an alleviated positive-aging effect (i.e., anomalous brightness increase). Concurrently, the operational lifetime T 95 (the time for the device luminance to drop to 95%) was also improved from 1,036 h to 2,084 h. Furthermore, by modulating the morphology of ZnO films, we successfully fabricated pixelated QLED devices, laying the technical foundation for commercializing high-resolution QLED displays.

Polyurethane acrylate (PUA) films are widely utilized in flexible electronics and optical devices owing to their mechanical robustness, elasticity, and high transparency. However, their performance rapidly deteriorates under thermal stress, severely limiting their long-term reliability. Here, we report the synthesis of a novel azacyclic polymer, 3,3′,3″-((1,3,5-triazine-2,4,6-triyl)tris(azanediyl))triphenol (TTT), which is incorporated into PUA matrices to enhance heat resistance. The resulting azacyclic-modified PUA film exhibits markedly improved thermal stability, increasing the onset degradation temperature by approximately 20°C. Furthermore, the tensile strength of the modified film demonstrates a 61% enhancement compared with the unmodified counterpart after exposure to 60°C for 4 h. Notably, the modified PUA maintains over 90% optical transmittance without haze after being aged at temperatures ranging from 50°C to 120°C for 4 h, thereby preserving the visual clarity required for display applications. This study provides a novel strategy for fabricating heat-resistant PUA films, offering a promising pathway toward next-generation encapsulation materials for flexible and wearable electronic systems.

C7–C10 aromatics are indispensable components of aviation fuels to meet the swelling need for sealing rings in aero engines. Aromatics with a short and single substituent have weak low-temperature reactivity, yet this may be enhanced under a fuel blend environment. In this work, we investigated low-temperature oxidation chemistry of n-propylbenzene, a representative C9 aromatic in a blend with n-heptane, in a jet-stirred reactor. Time-of-flight molecular beam mass spectrometry using synchrotron vacuum ultraviolet radiation as a photon ionization source was used for product analysis and species identification. Thirty-six species were identified by comparison of measured photoionization efficiency curves and calculated species ionization energies, and six of them are key reaction intermediates of n-propylbenzene oxidation. Kinetic model simulations captured the measured mole fractions of reactants, main products, and intermediates with some discrepancies. Furthermore, many oxygenated aromatics are missing in the model, reflecting insufficient understanding of n-propylbenzene low-temperature chemistry. Low-temperature oxidation pathways were proposed based on molecular structures of reaction intermediates. This work explored low-temperature oxidation of n-propylbenzene under a fuel blend environment, which might be useful to unravel the low-temperature chemistry of C7–C10 aromatics in practical jet fuels.

Fat content shapes rice eating and nutritional quality, yet its climate response remains unclear. In this study, we combined six years of multisite field observations across nine provinces in southern China with an interpretable random forest model to identify drivers of rice fat. The model showed that the minimum nighttime temperature during grain filling (TMIN) was identified as the primary factor. Fat content increased with TMIN, whereas the unsaturated fatty acid index (IUFA) exhibited three distinct accumulation patterns and generally declined at higher TMIN. This pattern indicates a physiological tradeoff potentially linked to changes in energy metabolism and membrane stability of rice. Patterns were independently validated in 2024 field trials at 11 sites. Furthermore, projections indicate higher fat under warming but declining IUFA, especially in early- and mid-season rice. These results support climate-resilient cultivation, sustainability, and quality management of rice.

For complex oily wastewater, establishing multi-scale in-situ anti-fouling separation membrane materials can effectively mitigate membrane fouling and achieve wastewater purification. Based on this, this study prepared a multifunctional membrane material (PC/Co 3 S 4 @NW) that combines super-wetting properties with catalytic functionality. The membrane's superwetting property originates from hydrogel encapsulation, with salt precipitation enhancing the hydrogel's stability. The PC/Co 3 S 4 @NW is exceptional in superhydrophilicity and underwater oleophobicity, enabling efficient separation of oil-water mixtures (separation efficiency >97%) and oil-water emulsions (separation efficiency >95%). The catalyst loading imparts to the PC/Co 3 S 4 @NW membrane the ability to catalyze the degradation of aqueous organic pollutants, achieving removal rates exceeding 99.5% for various dyes. This degradation effectively mitigates the decline in separation flux caused by membrane fouling. Furthermore, during a continuous filtration process lasting 10 h, the PC/Co 3 S 4 @NW membrane consistently maintained a dye removal rate of over 93%. Radical scavenging tests and degradation kinetic testing elucidate the membrane's catalytic mechanism. What's more, the PC/Co 3 S 4 @NW membrane can achieve significant purification efficacy for complex actual oily wastewater. This in-situ separation-catalysis strategy offers a viable pathway for purifying complex oily wastewater and efficiently mitigating membrane fouling.

Efficient encapsulating of highly hydrophilic low-molecular-weight compound within poly (D, L-lactic-co-glycolic acid) (PLGA) to obtain microspheres with both excellent drug loading capacity (DL) and encapsulation efficiency (EE) was substantially challenging. This study specifically aimed to enhance both the DL and EE of this hydrophilic low-molecular-weight compound S-propargyl-cysteine (SPRC) while extending its release duration through implementation of the solvent-induced phase separation (SIPS) methodology. S-propargyl-cysteine (SPRC)-loaded PLGA microspheres (SP-MSs) were fabricated using conventional emulsion solvent evaporation techniques (W/O/W and S/O/W) and compared with those prepared via SIPS. The influences of various preparation techniques on critical pharmaceutical properties of sustained-release SP-MSs, including drug loading capacity, encapsulation efficiency, in vitro release profiles, surface-localized drug content, crystal state of SPRC, and microstructural characteristics were also systematically investigated. Microspheres sythesized through SIPS demonstrated a remarkable enhancement in DL, increasing from 0.90% to 9.91%, with the corresponding EE improving dramatically from 17.8% to 99.2%. Furthermore, the SIPS approach effectively mitigated the initial burst release phenomenon commonly observed in polymeric microsphere formulations. In vivo pharmacokinetic studies in Sprague-Dawley rats confirmed the sustained-release profile of the optimized formulation, maintaining stable plasma concentrations for an extended period of seven days. These findings establish SIPS as a superior methodology for encapsulating SPRC within PLGA microspheres, effectively addressing dual challenges of low DL and EE. This investigation provides significant methodological insights for the effective encapsulation of hydrophilic low-molecular-weight therapeutic agents within PLGA-based delivery systems, offering a promising strategy for achieving prolonged sustained-release both in vitro and in vivo . Solvent-induced phase separation was employed to encapsulate highly hydrophilic S-propargyl-cysteine (SPRC) within injectable PLGA microspheres to (i) maximize EE and DL, (ii) suppress the initial burst, and (iii) achieve prolonged, controlled release of SPRC for 7 days both in vitro and in vivo .

The sustainable and efficient treatment of high-salinity radioactive wastewater containing 99 TcO 4 − represents a critical challenge, driven by the severe environmental risks of 99 TcO 4 − and the inadequacy of existing treatment technologies. Here, we introduced membrane distillation (MD) as a novel approach for such wastewater and developed a robust superhydrophobic membrane (# PVDF-PN ) that simultaneously resisted wetting and scaling while overcoming the conventional selectivity-permeability trade-off. The # PVDF-PN was fabricated through in situ hydrolysis and polymerization of trichloromethylsilane (TCMS) on hydroxylated polyvinylidene fluoride (PVDF), yielding a surface densely covered with low-surface-energy polysiloxane nanofilaments. This unique nanofilament architecture significantly enhanced the gas-liquid interfacial area for vapor evaporation, without compromising pore integrity or permeability due to surface modification. When tested with challenging feeds containing surfactants or supersaturated gypsum, # PVDF-PN maintained a stable flux of ∼33.0 kg·m −2 ·h −1 and near-complete salt rejection (>99.99%), outperforming both unmodified # PVDF and fluorinated silica-coated # PVDF-FS . Its exceptional performance was attributed to a high liquid entry pressure, an elevated energy barrier for crystal nucleation, and reduced liquid-solid contact area and interaction time. Importantly, in long-term MD treatment of simulated 99 TcO 4 − /ReO 4 − -laden high-salinity wastewater, # PVDF-PN achieved non-detectable effluent concentrations of target oxyanions, demonstrating its potential as a reliable and efficient solution for radioactive wastewater management and emergency response.

Hydroxyl-rich biomimetic particles are synthesized for bionic lotus/petal microstructures construction. • Direct-write printing of interchangeable inks creates superhydrophobic surfaces with programmable wettability • Interparticle hydrogen-bonding network and interfacial covalent bonds ensure mechanical durability. • The prepared surface enables applications such as liquid manipulation, anti−/de-icing, and patterning. Functional surfaces with controlled wettability are in high demand across fields. However, achieving such a surface property flexibly while ensuring its durability remains challenging. Here, inspired by natural organisms, we construct two types of biomimetic microstructures on target substrates, achieving low-adhesion (lotus effect) and high-adhesion (petal effect) superhydrophobic surfaces, respectively. Both microstructures are direct-write printed from dual-roughness biomimetic particles (BPs) and alkyl ketone dimer (AKD). The printing sequence determines their distinct wetting properties. The surface displays the lotus effect when AKD forms the outer layer (contact angle = 159.2°, sliding angle = 5.2°), granting it self-cleaning and anti-icing performance. The surface can resist scratching, peeling, and hundreds of severe abrasion cycles, which benefits from the high interfacial strength generated by the synergistic effect between the pre-formed interlinked network of BPs and the esterification with AKD. Crucially, when BPs are positioned on the outer layer, the surface switches to petal effect, where droplets remain pinned without sliding or falling off even when the surface is inverted (180°). By programming the printing path, this strategy is proven to exhibit significant promise in on-demand patterning and liquid manipulation.

Polydimethylsiloxane (PDMS) is a promising fluorine-free hydrophobic material for proton exchange membrane fuel cell (PEMFC) microporous layers (MPLs) owing to its low surface energy, environmental compatibility, and low-temperature curing. However, weak adhesion between low-loading PDMS and carbon materials limits the structural stability, especially under hydrothermal and oxidative conditions. Here, 3-aminopropyltriethoxysilane (APTES) is used to modify carbon black and enhance the carbon-PDMS interfacial interaction. An APTES-modified 5 wt% PDMS-MPL is compared with unmodified 5 wt% PDMS-MPL and conventional 20 wt% polytetrafluoroethylene (PTFE)-MPL. Hot-water and Fenton oxidative aging, combined with microstructural, pore, hydrophobicity, X-ray photoelectron spectroscopy (XPS), and single-cell electrochemical analyses, are used to evaluate aging-induced degradation and transport evolution. APTES modification reduces the ultrasonic mass loss rate from 11.67% to 5.17%, indicating improved interfacial stability. After aging, the modified MPL maintains a more stable pore structure and hydrophobicity and shows a mass-transfer resistance of 0.194 Ω cm 2 after Fenton aging. In contrast, unmodified PDMS-MPL exhibits polymer migration, local delamination, and oxidation, whereas PTFE-MPL retains a relatively stable pore structure but shows stronger high-current mass-transport limitations. These results demonstrate that APTES interfacial modification improves the structural stability and aging resistance of low-loading fluorine-free PDMS-based MPLs.

The coupling of biobased oxygenated fuels with low-temperature
combustion (LTC) technologies offers a promising pathway to reduce
dependence on fossil fuels and optimize compression-ignition combustion
processes. However, a systematic understanding of how the fuel molecular
structure regulates the reactivity of blended fuels remains limited.
In this study, using n -heptane as a diesel surrogate
fuel, the low-temperature combustion characteristics of methyl caprate
(MC), dipropylene glycol dimethyl ether (DPDME), and five other ether-ester
oxygenated fuels were investigated at various blending ratios using
a cooperative fuel research (CFR) engine system. The results indicated
that blending 40% and 60% MC yielded a superior fuel modification
effect; a minor ratio of DPDME blending was advantageous for enhancing
the oxygen content of the fuel. A 20% blend of MEA or 3-MTBA exhibits
favorable heat release intensity and ignition phasing, whereas PGMEA
and EGMEA are more suitable as low-ratio oxygenated additives. All
ratios of BGA blending combusted effectively, with 20% BGA blending
exhibiting optimal performance, characterized by an elevated exothermic
intensity and favorable ignition timing. With the proper combination
of fuel additives, favorable heat-release behavior and ignition phasing
can be obtained under the present CFR/LTC conditions, indicating the
potential of selected biobased oxygenated fuels as blending components
for diesel surrogate fuels. Furthermore, this study indicated that
a minor proportion of oxygenated fuel blending can alter the fuel
oxidation conditions and in-cylinder temperature, hence enhancing
the combustion performance and benefiting the whole combustion process.

Achieving real-time, high-sensitivity radiation detection with stability and precision remains a critical challenge in medical diagnostics and radiation therapy. Here, we report the development of MDABCO-NH4(BF4)3 single crystals (SCs), a metal-free perovskite material with exceptional performance for both X-ray and charged particle detection. Large-scale MDABCO-NH4(BF4)3 SCs (15 × 13 × 5 mm3) were synthesized via a simple low-temperature solution method, achieving superior crystallinity with a full width at half-maximum (fwhm) of 0.0061°. The MDABCO-NH4(BF4)3 detectors exhibit high resistivity (1.31 × 1012 Ω·cm), low trap density (1.09 × 109 cm–3), and excellent charge transport properties ((μτ)h = 3.15 × 10–5 cm2·V–1). For α-particle detection, the MDABCO-NH4(BF4)3 detectors achieve a high energy resolution of 35.0% at 5.49 MeV and a fast response time of 5 ms, demonstrating single-particle sensitivity. For X-ray detection, MDABCO-NH4(BF4)3 detectors exhibit high sensitivity (13,529 μC·Gyabs–1·cm–2) and an ultralow detection limit (17.1 nGyair·s–1), significantly lower than the 5.5 μGyair·s–1 standard for active personal dosimeters used in regular medical diagnostics. The combination of superior charge transport properties with stability and high signal-to-noise ratio establishes MDABCO-NH4(BF4)3 SCs as a versatile material for real-time radiation monitoring and high-precision medical imaging applications.

CO2 flooding technology demonstrates advantages such as injectability and miscibility in low-permeability reservoir development; however, asphaltene deposition during the displacement process leads to pore-throat blockage and permeability reduction. To address this issue, this study systematically investigated the inhibitory effects of three ionic liquids and one commercial inhibitor on asphaltene deposition in crude oil, with the underlying mechanisms elucidated through molecular dynamics simulations based on interaction energy. Additionally, CO2 flooding coupled with nuclear magnetic resonance was employed to quantitatively characterize the damage extent of asphaltenes to reservoir physical properties and pore structures during CO2 displacement. Experimental results demonstrated that after inhibitor addition, the asphaltene precipitation onset point of oil samples significantly increased from 34% to 52%, asphaltene aggregate particle size decreased from 1,082 nm to 410 nm, and turbidity values declined by 10–30%. This improvement is attributed to the ionic liquids’ ability to disrupt asphaltene molecular association via electrostatic interactions, steric hindrance, and hydrogen bonding, while simultaneously modifying the system’s polarity, thereby effectively inhibiting asphaltene deposition. Molecular dynamics simulation results exhibited strong consistency with experimental findings. The inhibitors mitigated the adverse impacts of asphaltene deposition on core porosity, permeability, and blockage rates. This study reveals that ionic liquids hold significant potential for inhibiting asphaltene deposition during CO2 flooding in low-permeability reservoirs.
