Perovskite quantum dots (PQDs) show promising potential in the optoelectronic field, but their commercial application is limited by the scalability in laboratory scale and complicated synthesis in an inert atmosphere, especially in I-based red-emission PQDs. The PQDs are disturbed by the performance decrease in the scalable synthesis caused by the trap states from weakly-bonded ligand loss and uneven nucleation/growth from the complicated injection process. Here, a 100-fold scalable (800 mL) and gram-level (2.19 g) synthesis of CsPbI 3 pure-red PQDs is achieved in ambient air. This is realized by a strongly-coordinated dual-ligand strategy with phosphorus-oxygen groups to interact strongly with Pb 2+ and protect PQDs from moisture/oxygen, ensuring the ambient air scalable synthesis. The 100-fold scaled-up PQDs show no significant emission shift or broadening (ΔPL = 0.7 nm, ΔFWHM = 0.8 nm) and remain over 80% PLQY. Also, pure-red light-emitting diode (LED) based on the scalable PQDs reserves 86.3% EQE of LEDs based on small-scale PQDs, showing the excellent batch consistency and commercial potential of PQDs.

Objectives:The industrial production of lanolin alcohol currently employs batch saponification, which suffers from high energy consumption, prolonged processing time, and excessive solid waste generation, rendering it incompatible with green chemistry principles. This study aimed to develop an efficient, sustainable saponification process by addressing these limitations through integrating large language models (LLMs) with microfluidic technology.Methods: An LLM-based intelligent agent called SapoMind (version 1.0) was constructed. SapoMind employs LLMs as its software core and a continuous-flow microreactor as the experimental platform. Its performance was enhanced through supervised fine-tuning. The system enables automated recommendation of saponification process parameters, autonomous experimental design, and automatic execution of experiments. Saponification conditions were automatically optimized considering product quality, energy consumption, material consumption, and time consumption.Results: The optimal continuous-flow saponification conditions were determined as 70 °C reaction temperature and 9 min residence time, producing lanolin alcohol complying with European Pharmacopoeia standards. Compared to batch processing, the optimized process reduced carbon emissions by 53% and solid waste by 37%, with the greenness score increasing from 82 to 93.Conclusions: This study demonstrates the effectiveness of LLM-driven intelligent agents in optimizing green chemical processes. SapoMind offers significant environmental and operational benefits for lanolin alcohol production.

To solve the problem of the deep eutectic solvents synthesized with small volume hydrogen bond acceptors and hydrogen bond donors entering the cavity of pore generator and occupying their pore structure, supramolecular deep eutectic solvent (SDES) was firstly introduced to construct porous deep eutectic solvent (PDES). Thereby, a PDES was synthesized by using ZIF − 8 encapsulating peroxophosphotungstate (PPT) as pore generator and SDES composed of methyl-β-cyclodextrin (M − β − CD) and levulinic acid (LA) as steric hindrance solvents. The characterization results indicated that PPT was encapsulated successfully within ZIF − 8 to prepare [PPT@ZIF − 8]. [PPT@ZIF − 8] and [M − β − CD/LA] remain structure stable after forming PDES and [M − β − CD/LA] do not fill the cavity of [PPT@ZIF − 8]. The PDES [PPT@ZIF − 8][M − β − CD/LA] was applied for oil desulfurization and the desulfurization rate of dibenzothiophene in model oils could reach 100% within 2.5 h using H 2 O 2 as oxidant. The desulfurization by [PPT@ZIF − 8][M − β − CD/LA] combined the extractive desulfurization with [M − β − CD/LA] as extractant and the oxidative desulfurization with [PPT@ZIF − 8] as catalyst. Furthermore, [PPT@ZIF − 8][M − β − CD/LA] has excellent regeneration performance. This work will provide a new route to construct PDESs and will promote the industrial application of porous liquids.

Janus membranes (JMs) promise advanced liquid separations, but fabrication speed, substrate universality, and precise configurational control remain challenging. Here, we report an ultrafast and universal interfacial engineering strategy to construct JMs with desirable micro-nano structures. Founded on a rapidly formed tannic acid/polyethyleneimine (TA/PEI) platform, the approach utilizes highly reactive stearoyl chloride (SC) for minute-scale hydrophobic modification. Crucially, a novel physicochemical control principle is revealed. Specifically, interfacial wettability and tension are modulated at the molecular level by phytic acid (PA). Through this modulation, the membrane's physical immersion depth is governed to provide unprecedented, quantifiable control over hydrophilic layer thickness during liquid-liquid interface modification. This enables tailored JMs exhibiting pronounced asymmetric super-wettability (water contact angle (WCA) difference >157°) and tunable unidirectional liquid transport. Demonstrated across diverse metallic and polymeric substrates, the resulting JMs show remarkable separation performance for challenging mixtures, alongside exceptional stability. This facile and controllable strategy overcomes previous limitations in speed, universality, and regulation of asymmetric configurations, offering a versatile platform for designing nano-engineered functional materials for sophisticated liquid separation applications.

Recently, the silicon quantum dots (SiQDs) were widely utilized in enhanced oil recovery (EOR) due to their ultrasmall size, high specific surface area and excellent dispersion stability. Herein, the amphiphilic pH responsive silicon quantum dots (AR-SiQDs) were synthesized via the mild method to stabilize smart Pickering emulsion. Both the carboxyl and cinnamyl aldehyde were successfully grafted on the AR-SiQDs surface as hydrophilic and hydrophobic responsive groups, respectively. The structure of AR-SiQDs was characterized by Fourier transform infrared spectrometer and X-ray photoelectron spectroscopy, and the response mechanism was demonstrated via the zeta potential and interfacial tension (IFT) analyses. The results revealed that the diffusion and adsorption behaviors of AR-SiQDs relied on the protonation/deprotonation of carboxyl and reversible dynamic covalent bonding of imines. Specifically, the AR-SiQDs reduced the oil/water IFT from 51.00 mN/m to 7.58 mN/m at pH of 10.09, whereas the IFT only decreased to 24.12 mN/m at pH of 4.26. The AR-SiQDs effectively emulsified oil at alkaline condition, while the demulsification was rapidly achieved in 30 min upon the addition of hydrochloric acid. The emulsion exhibited excellent recyclability to maintain small average droplets size (from 1.42 μm to 2.12 μm) after five emulsification/ demulsification cycles. The core flooding experiments indicated that the AR-SiQDs stabilized emulsion evidently enhanced oil recovery by 14.65% at pH of 10.09, highlighting the remarkable synergistic effect with alkali. The work provided the novel strategy for designing smart SiQDs and recyclable emulsions for EOR.

2-Methoxy-4-methylphenol (MMP), a biofuel and flavor, can be produced from lignin-derived vanillin via hydrodeoxygenation (HDO). Herein, CuPd nanoalloys were confined within SBA-15 for vanillin HDO. By tuning Cu/Pd mass ratio, a volcano-like trend in MMP yield and apparent turnover frequency (TOF) was observed. The optimized CuPd nanoalloy catalyst (Cu/Pd = 1) occupied the top position, achieving 96.3% MMP yield within 3 h, with the TOF of 323.5 h −1 , 3 times than that of monometallic Cu catalyst, while other CuPd nanoalloy catalysts, positioned either side, exhibited lower activities. Moreover, it maintained HDO activity over 20 runs, far beyond typical Cu catalysts (~5 runs). Fabricated via microwave-assisted strategy, the catalysts were confirmed by X-ray absorption fine structure and density functional theory calculations to form CuPd nanoalloys with Pd δ- and Cu δ+ pairs, enabling H 2 dissociation and C=O bond activation. This work demonstrates an efficient approach to robust and stable nanoalloy catalysts for biomass upgrading.

Atomic layer deposition (ALD) presents a promising avenue for improving the environmental stability of perovskite quantum dots (PQDs). However, standard ALD processes (120–200 °C) inevitably compromise the PQD lattice structure, while lower temperatures yield porous, non-protective films. To overcome this trade-off, we developed a sequential-temperature ALD strategy that synergizes low-temperature surface passivation with high-temperature densification. First, a low-temperature (65 °C) ALD stage deposits a surface modification layer around PQDs, which leverages energetic precursor molecules to selectively passivate surface/lattice defects, effectively suppressing non-radiative recombination within PQDs and boosting their luminescence efficiency. Crucially, this initial layer plays a pivotal role in preventing thermal degradation of the perovskite during subsequent processing and generates a hydroxyl‑rich surface. These reactive sites facilitate the second stage, a high-temperature (120 °C) ALD, to rapidly deposit a dense Al 2 O 3 protective barrier layer. Remarkably, this sequential process induces the formation of a chemically graded Pb–O–Al–O–Al 2 O 3 interfacial structure remediating defects within the initial layer, exhibiting intrinsic self-healing capability. The resulting CsPbBr 3 /Al 2 O 3 composite manifests exceptional environmental stability, particularly against moisture, representing one of the best performances reported to date for ALD-encapsulated bulk CsPbBr 3 films. Unlike complex hybrid encapsulation schemes, our streamlined, standalone ALD approach enables scalable PQD modification. White light-emitting diodes fabricated with these encapsulated PQDs demonstrate a wide color gamut (∼120% NTSC) and remarkable spectral stability. This work establishes a generalizable paradigm for ALD encapsulation of thermally sensitive materials.

The silicon quantum dots (SiQDs) exhibited application potential in enhancing oil recovery (EOR) owing to their ultrasmall size and extremely large specific surface area. In the present study, the temperature responsive silicon quantum dots (SiQDsP8400) were synthesized by grafting poly (ethylene glycol)-block-poly (propylene glycol)-block-poly (ethylene glycol) (PEG-PPG-PEG, average molecular weight was 8400) via facile and mild one-pot method, which were characterized by Fourier transform infrared spectrometer, X-ray photoelectron spectroscopy, dynamic light scattering and transmission electron microscopy. Their interfacial activity was systematically evaluated by interfacial tension, interfacial expansion modulus and water contact angle measurements. The SiQDsP8400 more effectively reduced the n-octane/water interfacial tension to 5.12 mN/m at 70 ℃, while that at 30 ℃ was 16.67 mN/m. The higher temperature weakened the hydrogen-bond interaction between grafted PEG-PPG-PEG and water molecule to promote the spontaneous migration of SiQDsP8400 to the interface. Then the stability and temperature response of SiQDsP8400 stabilized Pickering emulsion were evaluated. The EI value of emulsions was 86.58% at 70 ℃ after standing for 120 h, and then its sharp decrease in cooling process suggested their smart demulsification. Subsequently, the molecular dynamics (MD) was employed to confirmed the amphiphilicity changing of the PEG-PPG-PEG groups with increasing temperatures. Finally, the SiQDsP8400 stabilized emulsions enhanced oil recovery by 14.93% at 70 ℃ in core flooding experiment, and the produced emulsion conduct demulsification/re-emulsification cycles for 3 times by changing temperature. The study raised a novel design method for temperature responsive silicon quantum dots in EOR application.

Quasi-two-dimensional (quasi-2D) Ruddlesden-Popper (RP) perovskites characterized by self-assembled multiple-quantum-well structures are promising emitters for high-resolution displays. However, the stabilities of blue perovskite light-emitting diodes (PeLED) are major hurdles toward full-color applications. Here, we introduce wide-gap, high-mobility silver-copper-gallium-disulfide (AgCuGaS 2 , ACGS) quantum dot (QD) solids as novel hole transport layer (HTL) to address the bottlenecks of the short lifetime of blue PeLEDs through controllable charge transport. ACGS QD solids provide enhanced hole transport through adaptable band structure and high hole mobility of 0.191 cm 2 V −1 s −1 . In addition, Zn 2+ attached to surface of the ACGS QD, stabilize the halide anions through ionic interaction, thus suppressing ion segregation and lattice defect formation in quasi-2D perovskite. The resulting pure-blue PeLEDs (471 nm) based on ACGS QD solids achieve a maximum EQE of 6.92% and a record operating lifetime with T 50 (luminance drop to half of the initial value) of 78 min at 100 cd/m 2 , significantly higher than controlled devices based on organic HTL materials (18 min).

Deep-blue perovskite quantum dot (QD) emitters with narrow emission line widths are critical for next-generation wide-color-gamut QD displays. However, achieving narrow primary deep-blue emission perovskite QDs compliant with Rec. 2100 remains challenging. This difficulty mainly arises from the intrinsic phase segregation of mixed-halide perovskite QDs, the presence of defects, and the inhomogeneous distribution of halide ions among the particles. Herein, we develop a ligand-mediated strategy for the phase separation inhibition and surface reconstruction of CsPb(BrxCl1–x)3 QDs. Specifically, we implement a sequential ligand treatment protocol comprising ion exchange with methyltrioctylammonium chloride, surface cleaning using octylphosphonic acid, and defect passivation via CF3–PEABr. This approach effectively promotes a distinct intergrain isolation and facilitates the homogenized halide distribution throughout the QDs ensemble. The resulting deep-blue quantum dot light-emitting diode (QLED) exhibits stable electroluminescence emission with an ultranarrow full width at half-maximum (fwhm) of 13.4 nm. This achievement marks the narrowest fwhm record of primary deep-blue perovskite QLEDs to date, featuring a 99.1% gamut coverage of Rec. 2100 standard. This work proposes a feasible strategy for ultrahigh color purity deep-blue QLEDs tailored for Rec. 2100 wide-color-gamut displays.

Aggregation of long-chain quaternary ammonium compounds (LC-QACs) into aggregates (e.g., micelles) during material modification often limits their grafting efficiency in porous adsorbents like powdered activated carbon (PAC), thereby constraining performance in anionic pollutant removal. Herein, we report a supramolecular strategy that employs β-cyclodextrin (β-CD) to suppress CTAB aggregation, enabling monomeric diffusion and enhanced CTAB loading within PAC micropores. The resulting β-CD/CTAB–PAC composite achieves a high perchlorate (ClO 4 − ) adsorption capacity of 211 mg g −1 , significantly surpassing the conventional CTAB-modified PAC (87 mg g −1 ), along with remarkable selectivity (distribution coefficient > 10× higher than competing anions), stability (<8% leaching in 10-day immersion), and regenerability (>91% capacity retention over 6 cycles). Fixed-bed column tests validated its practical efficacy, treating >5400 bed volumes of contaminated water (500 μg L −1 ) to below the drinking standard of 70 μg L −1 . Furthermore, density functional theory calculations attribute the high selectivity to the low hydration energy of ClO 4 − . Its sparse hydration shell results in a lower energy penalty for desolvation, enabling a more direct and stronger electrostatic interaction with the quaternary ammonium sites compared to the heavily hydrated competing anions. Overall, this aggregation-suppression approach provides a generalizable route for optimizing LC-QAC-based functionalization of porous materials.

Perovskite quantum dot light-emitting diodes (QLEDs) offer superior efficiency and high colour purity, making them promising candidates for next-generation lighting and display technologies. However, fabricating the emissive perovskite quantum dot (QD) layer typically requires a protective atmosphere due to its air sensitivity, thereby increasing production costs and limiting industrial scalability. Here, we propose an ion-pair pinning strategy by using tetraalkylammonium triflate (NR 4 OTf) to enable ambient-air processing of formamidinium lead bromide (FAPbBr 3 ) QD films. The trifluoromethanesulfonic acid anions (OTf − ) hydrogen bond with FA + , inhibiting its detachment and passivating the uncoordinated Pb 2+ , while the tetraalkylammonium cations (NR 4 + ) serve as X-type ligands to inhibit deprotonation. This dual ion-pair pinning effect stabilises the QD lattice and provides surface resistance to moisture and oxygen, thereby improving the uniformity, stability, and optoelectronic performance of air-processed QD films. The as-constructed air-processed QLED achieves a high external quantum efficiency (EQE) of 21.3% and a peak luminance of over 3 × 10 4 cd m −2 at 529 nm with Rec. 2020 compliance (EQE of 23.9% and luminance of over 8 × 10 4 cd m −2 for the N 2 -processed QLED). Our work eliminates the reliance on inert gas protection in perovskite QLED fabrication, laying a foundation for their low-cost, large-scale manufacturing and expansion into diversified applications.
