The facet-selective growth of shells on green InP-based quantum dots result in their inferior electron confinement capabilities, posing a challenge for the realization of completely cadmium-free quantum dot light-emitting diode displays. Here, we develop a surface energy homogenization strategy based on ligand adsorption using n-octylamine and diphenylphosphine selenide, effectively suppressing selective growth of ZnSe on the InP (111) facet, resulting in strongly electron-confined InP/ZnSe/ZnS quantum dots with a quantum yield exceeding 92% and a full-width at half-maximum of 35 nm. The resulting quantum dot light-emitting diodes achieve a peak external quantum efficiency of 23.50% and a luminance exceeding 1.4 × 10 5 cd m -2 , with a 107.5-fold increase in device lifetime. Utilized asymmetric wettability-mediated assembly strategy, we achieved quantum dot arrays with an impressive resolution of 8460 PPI. Furthermore, integrating the quantum dots into an active-matrix LED display, we successfully demonstrate the display of both static and dynamic images.

A novel Ti-BTC with a mesoporous structure and uniformly dispersed Ti-OH sites was successfully synthesized. • Ti-BTC exhibits outstanding ODS activity; 99.5% of sulfur (1000 ppm) can be oxidized at 40 °C within 20 min. • The ODS activity of Ti-BTC at 40 °C reaches 52.4 mmol h −1 g −1 , exceeding that of most previously reported Ti-MOFs. • DFT results reveal that OH anchored on Ti sites react with H 2 O 2 to form Ti-OOH species that dominate ODS efficiency. • The mesoporous architecture enhances the accessibility of sulfur to Ti-OOH active sites and promotes rapid mass transfer. Desulfurization represents a pivotal process to produce ultraclean fuels, yet the design and fabrication of advanced materials to enhance desulfurization efficiency continues to pose significant challenges. Herein, a novel mesoporous titanium-based organic frameworks (Ti-BTC) was successfully synthesized via a solvothermal route. The optimized Ti-BTC exhibits outstanding oxidative desulfurization (ODS) performance, enabling the complete oxidation of various sulfur-containing compounds (1000 ppm sulfur) into the corresponding sulfones at 30 °C within 14 min or at 50 °C within 3 min with H 2 O 2 /sulfur (O/S) molar ratio of 5. Notably, even when molar ratio of O/S is reduced to 2.5, 99.5% of sulfur species are oxidized at 40 °C within 20 min. The ODS activity of Ti-BTC at 40 °C attains 52.4 mmol h −1 g −1 , surpassing most previously reported Ti-containing organic materials. Density functional theory calculation and comprehensive characterization results demonstrate that Ti-OH group anchored on vacancy Ti sites readily react with H 2 O 2 to generate peroxo-titanium intermediate, which efficiently oxidize pre-adsorbed sulfur and thus determine the overall ODS efficiency. Additionally, the mesoporous structure of Ti-BTC improves the accessibility of sulfur to in-situ-generated Ti-OOH species and facilitates rapid mass transfer, which synergistically enhances the catalytic performance.

Hypothesis Liquid-infused surfaces (LISs) have drawn considerable attention for their exceptional self-cleaning and antifouling properties. The interaction forces between the infusing lubricant and the substrate surface play a pivotal role in determining LIS stability and performance. However, there is a lack of directly measured intermolecular forces as quantitative experimental evidence to determine the contribution of lubricant chemistry in different environments at the molecular scale. Experiments In this study, the interaction forces of diverse functional groups representing typical infusing lubricants with polydimethylsiloxane (PDMS) and phenyltriethoxysilane (PTES) surfaces were directly measured using atomic force microscopy in air and in aqueous solution. Findings The force measurement results in air indicated that the adhesion of the functional groups was larger on PTES compared to PDMS, and the adhesion was primarily determined by van der Waals interaction. In aqueous solution, the adhesion on PTES became lower than that on PDMS across almost all the functional groups, except for the C C. This reversal could be attributed to the enhanced electrostatic repulsion between functional groups and PTES, as PTES carried more negative charges than PDMS. The large adhesion for C C on PTES measured in aqueous solution could be due to the effective π interactions between C C and the benzene ring on PTES. The force measurement results were further supported by molecular dynamics simulations, suggesting that the adhesions between lubricants and substrate surfaces were predominantly determined by the intermolecular interactions. The measured adhesion forces had a positive correlation with the lubricant retention as a higher adhesion force resulted in a lower reduction ratio of drop sliding velocity after air and water shearing. Notably, the n-octanoic acid ( COOH) exhibited the highest adhesion and the greatest resistance to shear-induced loss on PDMS both in air and under water. While 1-octene ( C C) exhibited the highest stability on PTES in an aqueous environment. This work established a molecular-level design framework for engineering robust LIS systems, offering practical guidelines for selecting lubricants suited to specific substrate surfaces.

TrTPFB is successfully introduced as a fluorinated ionic molecule into FAPbBr₃ PeQDs. • Multi-site interactions stabilize the PeQD surface and suppress nonradiative recombination. • TrTPFB induces p-type modulation, reducing interfacial charge accumulation. • Threefold enhancement in T₅₀ lifetime highlights improved device stability. Perovskite quantum-dot light-emitting diodes (PeQLEDs) remain limited by coupled surface and interfacial losses: labile ligand binding produces trap-rich perovskite quantum dot (PeQD) surfaces while unbalanced carrier injection accelerates interfacial charge accumulation and nonradiative recombination. Here, triphenylmethylium tetrakis(pentafluorophenyl)borate (TrTPFB) is introduced as a fluorinated ionic molecule to synergistically regulate both the surface coordination and charge-injection behavior of FAPbBr₃ PeQDs. Density functional theory (DFT) calculations reveal pronounced charge redistribution between TrTPFB and the PeQD surface. Experimental results show that the fluorinated tetrakis(pentafluorophenyl)borate (TPFB − ) anion and the positively charged triphenylmethylium (Tr + ) cation cooperatively stabilize the surface coordination environment and suppress trap-mediated nonradiative recombination. TrTPFB also induces p-type electronic modulation of the PeQD film, shifts the Fermi level toward the valence band, lowers the hole-injection barrier, and mitigates interfacial charge accumulation. Consequently, The combined operation of these mechanisms significantly improves the photoluminescence quantum yield (PLQY) of perovskite films to an impressive 98.50%. The corresponding green PeQLED achieves a peak external quantum efficiency of 17.50%, a maximum luminance of 80,859.28 cd m −2 , and an approximately threefold increase in the average T₅₀ lifetime compared with the control device. This work establishes a fluorinated ionic molecular strategy that integrates surface passivation and charge-injection regulation for efficient and stable PeQLEDs.

Superwetting materials are increasingly used in the field of oil/water separation due to their special surface wettability. Herein, a single-layer superhydrophilic/underwater superoleophobic material was rapidly prepared by ultrasound-assisted and seed-mediated growth methods using nickel foam (NF) as the carrier, polydopamine (PDA) as the binder, and HKUST-1 as the filler. Two sheets of modified NF were then laminated into a bilayer HKUST-1/PDA/NF composite and used for the separation of oil-in-water emulsions. The sonication time and HKUST-1 seed content were optimized during the preparation process, and their effects on the underwater surface wettability, separation flux, and efficiency were thus investigated. The as-prepared NF composite also exhibited remarkable antifouling performance and excellent thermal and chemical stability. Additionally, the unique three-dimensional structure of NF enabled its robust and wear-resistant property. After ultrasonication for about 1 h and 25 mechanical abrasions, the underwater superoleophobic angle still remained above 150°. More notably, under gravity drive, the as-prepared composite demonstrated superior separation efficiency above 98% for each of the selected oil-in-water emulsions. The developed method may offer a fast and facile approach to fabricate stable, chemically and mechanically robust materials with underwater superoleophobicity for the treatment of oily wastewater.

Maximizing the mass transfer rate and enhancing the effective spread of active sites and recovery of catalysts between various stages of reaction could help to realize catalytic oxidative performance. Colloidal catalysts can break through the bottleneck problems between solid and liquid catalysts. In this work, colloid Zr-MOFs materials were prepared for the first time as support, and CDUT-Colloid catalysts were prepared by combination with liquid active components. Catalysts exhibit efficient mass transfer characteristics and high dispersion of active sites characteristic of ILs, while possessing the advantages of easy recovery and high stability. The oxidative desulfurization performance approaches 100% under mild reaction conditions (m(CDUT-Colloid-2) = 0.5 g, t = 90 min, n(O)/n(S) = 10, 30 °C). This catalyst exhibits excellent recycling performance, stability of structure, absorbability, and suitable viscosity. The proper viscosity of the colloidal catalyst facilitates phase transfer at the interface, accelerating the transfer of sulfide from the oil phase to the colloidal phase. The phase interface after the reaction is easy to separate, ensuring purity of the final oil. Based on structural analysis, desulfurization performance, and the capture experiment of the transition state (•OH), the oxidative desulfurization reaction mechanism of the colloidal catalytic system can be obtained. The catalytic reaction mechanism can be divided into two steps of collaborative catalysis, which can reveal the uniqueness of the colloidal catalyst in the reaction process. This unique colloidal catalyst provides a research approach for catalysts and lays the foundation for the study of functional materials.

Anti-icing glass is particularly important for applications where ice formation can pose safety risks or impair functionality. The challenge of anti-icing modification for glass lies in maintaining water repellency while addressing the issue of transparency and durability. In this work, leveraging the robustness and wear resistance of inorganic/organic composite materials, a highly transparent coating, with strong adhesive properties to glass substrates and repellency to liquids has been developed. Briefly, 3-glycidoxypropyl polyhedral oligomeric silsesquioxane (GPOSS) is employed as a precursor to fabricate a high-strength, high-transparency coating through modification with acrylic acid and perfluorooctyl acrylate. The inorganic component imparts strength and wear resistance to the coating, while the organic component provides hydrophobic and near oleophobic features. Furthermore, a custom-built mechanical test instrument evaluated the absolute value of the de-icing shear force. The results reveal that at −20 °C, the fluorinated modified coating only exhibit a minimum de-icing pressure of 40.3 kPa, which is 75% lower than the unmodified glass substrate. As-prepared coating exhibits a transmittance of up to 99% and can endure a high-pressure water impact of 30 kPa for 1 min without cracking. Compared to existing anti-icing coating methods, the core innovation of the fluorinated GPOSS-based coating developed in this study lies in its inorganic/organic composite structure, which simultaneously achieves high transparency, mechanical durability, and enhanced anti-icing performance.

In this study, a series of novel Eu3+-activated NaLu(MoO4)2 (NLMO) red phosphors were synthesized for the first time using hydrothermal, sol–gel, and microemulsion methods with varying active agents. The properties of these phosphors, including phase purity, crystal structure, DFT calculations, morphology, luminescence characteristics, thermal stability, and internal quantum efficiency, were comprehensively characterized. The results indicate that the ethylenediaminetetraacetic acid disodium salt (EDTA-2Na)-assisted hydrothermal method is the most suitable approach for the preparation of the phosphor. This method yields phosphors with a regular morphology, outstanding luminescence performance, relatively good thermal stability, and significantly high internal quantum efficiency. The internal quantum efficiency reaches 96.45%, and the phosphor exhibits good thermal stability, with the emission intensity at 423 K remaining about 73% compared to the initial temperature. The CIE chromaticity coordinate of the NLMO/0.13Eu3+ sample (0.667, 0.333) is very close to the standard chromaticity coordinate value (0.670, 0.330) from the National Television Standards Committee (NTSC). Remarkably, the color purity of the NLMO:0.13Eu3+ phosphor is an impressive 97%. Furthermore, Tb3+ was cointroduced in the NLMO:0.13Eu3+ phosphor, and its positive effects are discussed. Ultimately, a warm white light-emitting diode (W-LED) was fabricated using the studied NLMO:0.13Eu3+ phosphor with a 394 nm near-ultraviolet-emitting LED chip as the excitation source. The W-LED exhibits excellent properties such as high color purity, excellent correlation color temperature, and high color rendering index. Considering all of the results, the NLMO/Eu3+ red phosphor obtained by the EDTA-2Na-assisted hydrothermal method is an ideal red component for W-LEDs in various lighting applications.

High-performance pure-red perovskite light-emitting diodes (PeLEDs) are promising candidates for optoelectronic applications due to their remarkable photophysical properties. However, the unstable surface and insulating long-chain capping ligands of perovskite quantum dots (QDs) pose challenges to their commercialization by compromising stability and performance. Here, a simple but effective approach was demonstrated to synthesize highly stable red CsPbI3 QDs by introducing a multifunctional molecule, phenformin hydrochloride (PhenHCl), as an additive ligand. While the biguanide functional group in PhenHCl formed multiple hydrogen-bond interactions with the lead halide octahedron, the excess Cl– anions compensated for the iodine vacancies and eliminated trap states in the CsPbI3 QDs. The synergistic effect of the biguanide functional group and halogen compensation significantly passivated surface defects of the red CsPbI3 QDs, yielding a photoluminescence (PL) quantum yield of 98.6% and excellent ambient stability with 90% PL intensity retention over 80 days. The resulting pure-red PeLEDs based on the PhenHCl-treated CsPbI3 QDs were demonstrated to show a remarkable enhancement in the electroluminescence performance at around 649 nm, with an external quantum efficiency of 13.38%, and a maximum luminance of 2159 cd m–2. Our findings in this work provide an avenue by modulating the surface chemistry of CsPbI3 QDs to enhance the performance of pure-red PeLEDs.

Metal-organic frameworks (MOFs) have attracted significant attention in catalysis due to their permanent porosity and abundance of active sites. However, mass transfer limitations and low active site utilization in heterogeneous reactions have hindered the efficient production of active oxygen species in catalytic processes. Fortunately, MOF-based porous ionic liquids integrate the catalytic activity of solid catalysis and fluidity of ionic liquids. Herein, we synthesized UiO-66-based porous ionic liquids (PIL-UiO-66) for catalytic oxidative desulfurization. The cavity of the UiO-66 moiety has been confirmed to be empty through gas uptake studies and molecular dynamics simulations. Due to the imidazolium-based ionic liquid with superb mass transfer accelerating production of active oxygen species, PIL-UiO-66 demonstrated an enhanced desulfurization efficiency (98.3%) than UiO-66 (33.1%). Ultimately, the oxidation mechanism was revealed by the experimental results along with the theoretical calculations the oxidation mechanism. These findings provide an effective approach to developing MOFs-based PILs as catalysis.

The development of highly active catalysts is crucial for oxidative desulfurization (ODS) to meet the growing demand for sulfur-free fuels. In this study, a defect-rich composite catalyst UiO-DAlaPW was successfully synthesized via mechanochemical grinding, wherein phosphotungstic acid (HPW) was encapsulated within a defect-engineered UiO-66 framework, utilizing D-alanine (DAla) as a bridging molecule. The synthesized catalyst, UiO-DAlaPW, significantly enhances the utilization efficiency of hydrogen peroxide (H 2 O 2 ). In the model oil ODS system, the material exhibited exceptional catalytic performance: achieving deep desulfurization at room temperature within merely 5 min under conditions of extremely low acetonitrile cosolvent usage and a low oxidant/sulfur (O/S) ratio, accompanied by remarkably high H 2 O 2 utilization efficiency. Moreover, the catalyst maintained high desulfurization efficiency even in the absence of acetonitrile. Characterization by XRD, FT-IR, TGA, and XPS confirmed the successful encapsulation of HPW within the UiO-66 framework. Mechanistic studies revealed a significant synergistic effect between UiO-66 and HPW. The effective cooperation of the two active sites, namely Zr in UiO-66 and PW, significantly enhances the catalytic performance, contributing to superior oxidative desulfurization activity.

High pixel resolution is critical for next-generation quantum-dot light-emitting diode (QLED) display technologies. Although advances in quantum-dot patterning have improved resolution, the reduction in pixel size often degrades emission efficiency and pattern uniformity. Here we develop a nanoimprint strategy using nanohole-array moulds to fabricate nano-QLEDs via capillary action-induced self-assembly of quantum dots. We realize pixels as small as sub-100 nm with ultrahigh pixel resolution up to 169,333 pixels per inch over an electroluminescent area of 4 mm 2 . Benefiting from the closely packed light-emitting quantum-dot monolayers, our nano-QLEDs show minimal performance degradation upon reducing the pixel size. Notably, the smallest red, green and blue nano-QLEDs maintain average external quantum efficiencies of 17.0%, 10.5% and 5.7%, respectively. We also demonstrate fabrication on flexible substrates as well as an active-matrix display by imprinting micro-QLEDs on a thin-film-transistor backplane, showing images and videos with a resolution of 100 pixels × 180 pixels. This work provides a powerful method for fabricating ultrahigh-resolution nano-QLED arrays with high external quantum efficiency for next-generation displays.
