Micro quantum-dots light-emitting diodes (Micro-QLEDs) is a pivotal evolution in QLEDs displays. Inheriting the advantages of conventional QLEDs, such as wide color gamut, narrow emission bandwidth, and self-emissive properties while achieving ultra-small size. However, current fabrication methods for Micro-QLEDs are limited by complex processing, efficiency degradation, and high manufacturing costs, which hinder their commercialization. In this study, we employ an all inkjet-printing (AIJP) approach to overcome the compatibility limitations of conventional inkjet processes. In particular, A self-emissive red Micro-QLEDs with the structure ITO/PEDOT:PSS/TFB/QD/ZnO/Ag by stacking 5-soluble layers without intermixing. Its size has been scaled down to 30 μm—the smallest light-emitting area QLEDs for AIJP reported to date. The red Micro-QLEDs achieves the maximum external quantum efficiency (EQE) of 7.35% and a current efficiency of 11.19 Cd/A and the highest brightness of 61,377.41 Cd/m 2 . Accurate printing and uniform film formation were realized through systematic ink formulation optimization. The AIJP process offers significant advantages, including simplified fabrication, high material utilization, and independence from photolithography. This work represents a critical step toward the industrial production of full-color Micro-QLEDs displays and demonstrates strong potential for applications.

Covalent organic frameworks (COFs), characterized by tunable porous structures and functional surfaces, have emerged as promising adsorbents for efficient separation and enrichment of radioactive iodine. However, the constructing of two-dimensional (2D) COFs that expose a high density of adsorption sites to achieve both high adsorption capacity and rapid kinetics remains a significant challenge. In this work, hollow COF (H-COF) were synthesized using a dynamic micellar assembly strategy in an emulsion system, employing Pluronic F127/P123 dual surfactants as a soft template. The H-COF exhibited hollow features, enhanced pore size distribution, pore capacity, and pore connectivity, providing more accessible pathways for accelerating iodine molecule diffusion. Impressively, the H-COF demonstrated a superior iodine adsorption capacity of 9.25 g·g −1 . In addition, the K 80% adsorption rate of H-COF was 0.93 g·g −1 ·h −1 , which is 9.3 times higher than that of conventional C-COF (0.10 g·g −1 ·h −1 ), highlighting its significantly faster adsorption kinetics. Mechanism analysis and DFT calculations revealed that polyiodide anions (I 3 − and I 5 − ) form through electron transfer from the imine groups in H-COF to iodine molecules, with a strong adsorption affinity for the imine bonds. This study presents an efficient iodine capture material and the potential of COFs in waste management.

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.

CsPbBr 3 perovskite solar cells (PSCs) have attracted increasing attention due to their superior thermal and environmental stability; however, their power conversion efficiency (PCE) remains limited by uncontrolled crystallization and high defect density during solution processing. Meanwhile, the widespread use of toxic antisolvents and the limited effectiveness of single control strategies necessitate the development of greener and more effective fabrication methods. To address these issues, this study introduces a green mixed antisolvent by incorporating isopropanol (IPA) into ethyl acetate (EA), coupled with a three-step spin-coating process for the deposition of CsPbBr 3 films. By adjusting the volume fraction of IPA in the mixed antisolvent, the crystallization of CsPbBr 3 films was effectively regulated, resulting in dense, uniform films with low defect density. At an optimal IPA volume fraction of 10%, dense and hole-free CsPbBr 3 films were obtained with markedly suppressed non-radiative recombination. As a result, the corresponding CsPbBr 3 PSCs exhibited a significantly enhanced PCE of 8.15%, compared with 5.63% for devices processed using pure EA. Moreover, the optimized device retained 97.9% of its initial efficiency after 30 days of storage under ambient conditions without encapsulation. This work provides a practical solution for fabricating effective and environmentally friendly inorganic perovskite photovoltaic devices.

d-ribose, a key molecule in energy metabolism with wide applications in pharmaceuticals and functional foods, requires optimized crystallization for industrial production, where solubility is a critical thermodynamic parameter. Existing studies have limitations: narrow temperature ranges for solubility data (20–40 K) and insufficient understanding of how solvents affect solubility mechanisms. This study combines experimental and computational approaches: it measures d-ribose solubility in methanol, ethanol, 2-propanol, and 1-butanol across 293.15–333.15 K, analyzes the data, characterizes crystals formed in ethanol, and explores molecular interactions. Results show solubility follows the order: methanol > ethanol > 2-propanol > 1-butanol, increasing with temperature. Solubility differences correlate with solvent polarity, driven by hydrogen bonding interactions. Ethanol is identified as the optimal crystallization solvent due to moderate solubility, significant temperature sensitivity, and low toxicity. This work provides essential thermodynamic data and molecular insights for optimizing d-ribose production processes, while establishing a predictive framework for understanding functional sugar dissolution in alcoholic solvents.

Gas-phase catalytic synthesis of glycolide (GL) from methyl glycolate (MG) offers a promising route for sustainable production of polyglycolic acid, yet suffers from unfavorable catalytic performances due to limited mechanistic understandings. Here, a series of Ti/SiO 2 catalysts supported on mesoporous materials with distinct pore structures were synthesized to elucidate the structure–performance–mechanism relationship. Among them, Ti/KIT-6 exhibited the highest MG conversion and GL yield, attributed to its large pore size, three-dimensional interconnected mesostructure, and well-dispersed tetrahedral Ti(IV) species. Comprehensive structure characterizations and mechanistic studies establish a linear correlation for MG conversion rate and GL formation rate with the tetrahedral Ti(IV) content, pointing to Ti(IV) as the intrinsic active sites. Further combining with temperature-programmed and in situ spectroscopy experiments, a possible reaction mechanism is proposed for MG-to-GL on the active site. This study provides mechanistic insights to guide design of Ti-based catalysts for gas-phase ester cyclization reactions.

Semiconductor-based photocatalysis using TiO2, ZnO, and related materials offers a promising solution for efficient wastewater treatment through light-assisted advanced oxidation processes. In this study, oxygen vacancy (Ov)-rich ZnO micrometer-sized particles (ca. 0.5 μm) are grown on a conductive carbon cloth via a one-step molten salt method. The effects of different coordinating anions added into the molten salt on the morphological characteristics of the resultant ZnO crystallites are studied. The optimized photocatalyst (CC@ZnO-3 min) achieves near-complete degradation of 20 ppm ofloxacin within 2 h under UV irradiation and in the presence of 5 mM KHSO5 (PMS). In the absence of PMS, it removes 26% of total organic carbon (TOC) after 8 h─a 6-fold improvement over commercial ZnO with an average particle size of ca. 0.2 μm, which is also immobilized on carbon cloth with a similar loading mass of ca. 7.0 mg·cm–2. Radical trapping experiments reveal that superoxide (·O2–) and holes play dominant roles in the degradation process. The engineered oxygen vacancies not only enhance charge carrier separation but also significantly improve electron transfer efficiency. This work presents a strategy for developing high-efficiency photocatalysts to address pharmaceutical pollution.

Barium titanate (BaTiO3) exhibits high chemical stability; however, the relatively rapid recombination of charge carriers severely limits its photocatalytic performance. Meanwhile, electrocatalysis facilitates charge transport by generating a spontaneously polarized electric field, effectively suppressing charge carrier recombination, but the performance of conventional ferroelectric catalysts is inherently constrained by their low surface piezopotential. In this study, a piezo-photocatalytic system triggered by ultrasonic vibration is reported, based on BaTiO3 nanobats. The BaTiO3 structure resembles a nanobat, featuring a thicker lower cylindrical body (∼35 nm diameter) and a thinner upper section (∼20 nm diameter) with a total length of about 250 nm. It can generate a piezo-potential as high as 1.2 V through COMSOL finite element simulation. Under mild vibration, the BaTiO3 nanobats exhibit superior piezo-photocatalytic performance, converting CO2 into CO with a maximum yield of 101.18 μmol·g–1·h–1. The yield is approximately five times higher than that achieved with ultraviolet light irradiation alone. Furthermore, theoretical calculations reveal that the adsorption and desorption of intermediates (*COOH, *CO) on BaTiO3 can be regulated by applying different strains. The piezo-photocatalytic CO2 reduction reaction opens an avenue beyond conventional photocatalysis, expanding energy utilization to pave the way for carbon neutrality.

The advancement of catalysts that are both platinum-group-metal (PGM)-free and iron-free is essential for the oxygen reduction reaction (ORR), which is kinetically slow, particularly in anion-exchange membrane fuel cells (AEMFCs). One of the primary obstacles lies in achieving adequate activity and stability within the membrane electrode assembly (MEA) under real-world hydrogen-air operating conditions. Herein, an effective MnN4 site encased within N-doped carbon nanofibers (denoted as MnN4@N-CNFs) is designed for efficient ORR electrocatalysis. Benefiting from the electronic structure modulation of MnN4 moieties through strong interfacial coupling with the carbon matrix, and structural advantages of the 3D hierarchical porosity synergizing with N-doped carbon-MnN4 coordination systems, the as-resultant MnN4@N-CNFs demonstrate a high half-wave potential of 0.89 V, outstanding durability, and impressive methanol tolerance under alkaline environments, outperforming commercial Pt/C and a diversity of reported counterparts. Notably, the engineered catalyst demonstrates remarkable fuel cell performance with a peak power density of 222.0 mW cm–2 during practical AEMFC operation, while maintaining stable operation for over 15 h, representing a 3-fold enhancement over conventional Pt/C-based counterparts. This study establishes fundamental design principles for high-efficiency AEMFCs through atomic-level engineering of precisely coordinated metal–N–C active sites, providing a robust framework for next-generation electrocatalyst development.

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.

The key to removing and detecting trace Hg (II) in water is to achieve rapid adsorption and high adsorption capacity of the adsorbent while maintaining the simplicity and safety of the adsorbent preparation process. Herein, we report a post-modification of covalent organic frameworks by medical antidote dimercaprol (DMC-COF) for efficacious removing and detection on trace Hg (II) in water. The as-prepared DMC-COF showed excellent selectivity to trace Hg (II) and fast adsorption dynamics, which was attributed to the abundance of sulfhydryl and hydroxyl sorption sites in the COF mesopores and on the COF surface. The effluent concentration of Hg(II) coexisting with Ca(II) reduced from 30 μg·L −1 to the permissible limit (1 μg·L −1 ) of potable water standard within 30 s. The sorption equilibrium was achieved during 3 min and the adsorption rate reached over 98 %. The material also showed a wide applicable pH range (3.5–9.5), excellent regeneration feasibility and selectivity of Hg(II) coexisting with a wide range of heavy metals in tap water, and the effluent concentration of Hg(II) coexisting with trace of As(V), Cr(VI), Cd(II) and Pb(II) could reduce from 30 to 0.19 μg·L −1 during 10 min. Moreover, Hg(II) of 3, 6, 10 and 30 μg·L −1 in tap water could be achieved to meet the WHO standard within 1 min. Meanwhile, its conjugated framework could be used as a signal sensor for rapid testing for low concentration Hg(II) in water, with a fluorescence detection limit of 1.06 mg·L −1 . DFT calculations yielded the optimized structure of DMC grafted onto COF-V, revealing that Hg²⁺ and Hg(OH)₂ primarily adsorbed at the -S and -SH sites, predominantly through van der Waals interaction, whereas Hg(OH)⁺ mainly adsorbed at all the -S, -SH and -OH sites, governed by notable attraction.

Intelligent electrochromic systems that integrate energy storage with optical feedback are increasingly sought after to meet the demands of global energy transition and the burgeoning field of flexible electronics. Yet, the performance and reliability of flexible zinc-based electrochromic energy storage devices (EESDs) are often compromised by the limitations of conventional electrolytes, including poor interfacial stability, liquid leakage, and inadequate mechanical robustness. Herein, we report a high-performance flexible EESD based on a Prussian blue–zinc (PB–Zn) chemistry, enabled by a scalable blade-coated PB cathode and a quasi-solid-state electrolyte (QSSE) incorporating a semi-interpenetrating polymer network (semi-IPN) of poly(vinylidene fluoride- co -hexafluoropropylene) (PVDF-HFP) and ethoxylated trimethylolpropane triacrylate (EOTMPTA). The device delivers a high optical modulation of 74.49%, a coloration efficiency of 189.77 cm 2 C −1 , and outstanding cycling stability with 93.72% retention after 10,000 cycles, attributed to a stabilized electrode–electrolyte interface enabling highly reversible zinc electrochemistry. Moreover, the system demonstrates efficient self-powered operation when integrated with a solar cell (SC), highlighting its potential for energy-autonomous smart windows. Overall, this work establishes a material–interface co-design strategy that provides a promising pathway toward durable, high-performance, and self-sustaining electrochromic smart windows.
