Near-infrared-emitting copper-based I-III-VI quantum dots (QDs) hold significant promise for photonics and bioapplications, yet their broad photoluminescence (PL) emission severely limits color purity and device efficiency. Herein, we report a hierarchically staged synthesis that decouples and sequentially suppresses defect- and phonon-induced broadening. Starting with Zn-poor CuInSe 2 QDs via cation exchange, we introduce Zn 2+ alloying to passivate cation vacancies and homogenize composition, forming a defect-minimized core. Subsequent epitaxial overcoating with a thick ZnS shell strongly localizes excitons, evidenced by suppressed thermal quenching and dominant coupling to a higher-order longitudinal optical ( LO ) phonon mode of ZnS ( E LO ≈ 141 meV). This shifts recombination from defect-assisted to near-band-edge emission, yielding CuInZnSe/ZnS QDs with an ultranarrow linewidth of 111 meV, high PL quantum yield of 73%, and minimal Stokes shift of 42 meV at 977 nm. When integrated into luminescent solar concentrators, these QDs enable an optical efficiency of 8.81% and a power conversion efficiency of 2.79%, underscoring their practical utility. Beyond reporting materials, this work provides profound insights into the interplay of exciton confinement and defect engineering, establishing a general and instructive strategy for achieving high color purity in multinary QDs.

Electrowetting represents a promising approach for the precise manipulation of liquids at the microscale and possesses considerable potential for advancements in digital microfluidics. However, anti-penetration failures and interfacial gap defects in multilayer films markedly increase leakage current, which inevitably cause device failure, threatening a critical challenge for practical implementation of electrowetting devices. This study presents a fluorosilane molecular welding strategy to achieve atomic-scale chemical bridging at dielectric/hydrophobic interfaces. The approach demonstrates a peak leakage current of 330 pA/cm 2 , effectively reducing penetration current by 97.4%, while maintaining the average current fluctuations at an exceptionally low picoampere level. We elucidate the coupling effect between current leakage and failure in electrowetting displays and address this issue through a dual-barrier design, ultimately achieving a display device that maintains a stable aperture ratio of 67% without any microscopically observable electrode damage after 9 million cycles at potential engineering application level, even under accelerated aging conditions. This advancement contributes to the development of electrical breakdown resistance functional interfaces and improves the reliability of industrial devices, thereby benefiting emerging microfluidic applications such as reflective displays and dynamic microlenses.

Organophosphate diesters (di-OPEs) and hypochlorous acid (HOCl) are two typical indoor pollutants, which have been proved to negatively impact respiratory health. However, the underlying molecular mechanism of them acting on pulmonary phospholipids remains poorly understood. In this study, using 1-palmitoyl-2-oleoyl-sn-glycero-3-phospho-(1′-rac-glycerol) (POPG) as a model phospholipid, di-OPEs were found that can significantly amplify interfacial chemical damage induced by HOCl. This damage amplification effect can be observed in both alkyl- and aryl-di-OPEs, which shows concentration-dependence. This phenomenon can be attributed to two synergistic effects. Firstly, acidic phosphate group of di-OPEs lowers the system pH. This stabilizes HOCl in its undissociated neutral form, thereby preserving the highly oxidative reactivity of HOCl. Secondly, the lipophilicity of di-OPEs promotes their accumulation at the air-water interface, which elevates the H⁺ concentration in interfacial region. Such high interfacial concentration of H + aggravates the hydrolysis of POPG, thereby intensifying the overall chemical damage. Overall, this study offers a molecular level insight for clarifying the health implications of indoor di-OPEs in the presence of HOCl and lays the groundwork for evidence-based risk assessment.

La 2 O 2 CO 3 -Cu-Al mixed oxides (CL X A-LDO) were fabricated via the calcination of lanthanum carbonate-doped Cu-Al layered double hydroxides (LDHs) with unique wool-scale-like lamellar structures. CL X A-LDO were employed for the synthesis of dimethyl carbonate (DMC) via the transesterification of methanol with propylene carbonate (PC). Characterization via XRD, FT-IR, TG, and SEM confirmed that lanthanum carbonate-doped Cu-Al LDHs with unique wool-scale-like lamellar structures were successfully prepared. After calcination, these precursors transformed into La 2 O 2 CO 3 -CuO-Al 2 O 3 composites. CO 2 -TPD and XPS results indicate that CL 1.0 A-LDO-600 possesses abundant medium/strong basic sites and a favorable O II /O I ratio. Consequently, CL 1.0 A-LDO-600 exhibited a PC conversion of 68.44% and a DMC yield of 67.84% under mild conditions (80 °C, 2 h, catalyst loading 2.0 wt%, methanol/PC molar ratio = 10). Moreover, CL 1.0 A-LDO-600 demonstrated high stability, with only a modest activity loss (Δ PC = 6.2%) after six consecutive cycles. The kinetic analysis indicated a complex reaction mechanism. However, this behavior was effectively simplified to a pseudo-first-order reaction model, providing activation energies of Ea(k + ) = 47.17 kJ·mol -1 (forward) and Ea(k - ) = 44.46 kJ·mol -1 (reverse). The experimental data were systematically validated using a particle swarm optimization-backpropagation artificial neural network (PSO-BP) model. The hybrid model demonstrated superior predictive accuracy, achieving R 2 values of 0.9956 and 0.9916 for the training and testing sets, respectively, thereby outperforming the conventional BP model. This work provides fundamental insights into the rational design of LDHs-derived mixed oxide catalysts for sustainable DMC synthesis.

Efficient capture of residual NH₃ from Haber-Bosch recycling gas is essential to improve process efficiency and reduce environmental impact. In this study, a series of sulfonated porous organic polymers (PTO-1S, PTT-1S, PTF-1S) were fabricated by a post-sulfonation strategy using phenolic hydroxyl-containing precursors to capture NH 3 . Comprehensive characterizations of the sulfonated derivatives demonstrated not only the successful grafting of –SO₃H groups, but more importantly, a cooperative effect with the native phenolic –OH groups. The optimized PTO-1S achieves an outstanding NH₃ capacity of 11.52 mmol/g (at 298.2 K and 1 bar), with particularly impressive performance at low pressures (5.56 mmol/g at 313.2 K and 0.03 bar), surpassing most reported adsorbents. Mechanistic studies revealed that this cooperation creates an optimal balance of strong chemisorption (–SO₃H) and reversible hydrogen bonding (–OH), which is identified as the origin of the high capacity and exceptional cycling stability (< 1% capacity loss/cycle). Besides, the sulfonated samples maintain excellent selectivity under simulated industrial conditions (NH₃/N₂/H₂ mixtures) and a rapid adsorption rate (90% saturation within 2 min), demonstrating their potential for practical NH₃ recovery applications.

The extensive use of the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) calls for the development of robust methods for its trace-level monitoring in the environment, owing to the associated ecological and health risks. Herein, a novel molecularly imprinted photoelectrochemical (PEC) sensor is rationally designed for the ultrasensitive and specific detection of 2,4-D. The sensor is constructed on a synergistic Tin(III) oxide/multi-walled carbon nanotube (Sn 3 O 4 /MWCNT) nanocomposite, where Sn 3 O 4 nanoflowers act as an efficient photoactive matrix and the MWCNTs serve as an electron highway. This synergy significantly enhances charge separation, suppresses recombination, and provides a strong, stable photocurrent. A highly selective molecularly imprinted polymers (MIPs) layer is subsequently fabricated on this composite via in situ electrophmerization of pyrrole, creating specific recognition cavities for 2,4-D. The resulting MIP-PEC sensor displays an ultra-broad linear range spanning five orders of magnitude (0.1 nM ∼ 100 μM) and achieves an impressively low detection limit of 16.1 pM (S/N = 3). It also demonstrates excellent selectivity against structural analogs, high reproducibility, and satisfactory recoveries (93.8–106.7%) in real water samples. This work not only provides a robust analytical tool for trace pesticide analysis but also offers a versatile sensing strategy through the integration of advanced nanomaterials with molecular imprinting technology.

The rapid growth of flexible Internet of Things devices and multisensory human-computer interaction necessitates advanced systems capable of multimodal data sensing, processing, and feedback in an intelligent and energy-efficient manner. However, conventional architectures face limitations in energy inefficiency and interface mismatch due to the fragmented architecture of sensing, processing, and feedback units. Inspired by biological sensory systems, we introduce an MXene-based flexible dual-mode sensing-processing-visualizing integrated system into a single wearable device through a hierarchical MXene platform combining piezoelectric nanogenerators (mechanosensation), optoelectronic synapses (visual processing), and color-shifting quantum dot light-emitting diodes (optical feedback) with optimized interfaces. The wearable integrated system demonstrates tactile-visual signal recognition capabilities, biological self-protection behavior to adapt to environmental stimuli, dynamic trajectory recognition, and spatial positioning for motion recognition, which are highly desired in multisensory interaction. The bio-inspired material-architecture-function co-design strategy and integrated system promote the development of wearable neuromorphic hardware, edge computing, and intelligent human-machine interaction.

Aflatoxin B1 (AFB1) contamination in soybean kernels poses a persistent food safety challenge. This study evaluated the coupled ultrasound–ozone (US/O 3 ) process for AFB1 removal from soybean kernels. After 10 min of treatment, the US/O 3 process removed 96.2 % of AFB1, far exceeding ozone alone (54.5 %), ultrasound alone (36.9 %), and water washing (18.1 %). Mass balance analysis showed that only 10.4 % of the initial AFB1 remained in the kernels and soaking water after US/O 3 treatment, indicating that the process mainly destroyed AFB1 rather than merely transferring it into the liquid phase. A positive, time-dependent synergy factor quantified the cooperative effect between ultrasound and ozone. Electron spin resonance (ESR) spin-trapping combined with radical scavenging experiments identified hydroxyl radicals (HO • ) as the dominant oxidants. Identified transformation products suggested an initial attack on the terminal furan ring, followed by extensive hydroxylation, ring opening, dealkylation, and fragmentation to low-molecular-weight phenolic products. ECOSAR predictions showed higher LC 50 values for most products than for AFB1, indicating reduced acute toxicity. Fourier transform infrared (FTIR) spectra, color parameters, and lipid oxidation indices indicated negligible changes in soybean composition and quality. Therefore, the US/O 3 process offers an efficient, quality-preserving strategy for mitigating AFB1 contamination in soybean kernels.

The environmental fate of extracellular DNA is significantly influenced by its interaction with widely used biochar. However, a systematic understanding of how DNA chain length and biochar properties jointly govern the adsorption process, mechanism, and subsequent DNA stability remains limited. This study systematically investigated the adsorption behaviors and mechanisms of short-stranded (sDNA) and long-stranded DNA (LDNA) on biochars produced at 300 – 600°C under neutral pH conditions. sDNA exhibited a higher adsorption capacity (5.91 mg g -1 on BC600) by accessing internal mesopores on biochar, whereas LDNA showed a lower adsorption (2.22 mg g -1 on BC600) and a stronger desorption hysteresis, resulting from multisite anchoring with biochars. The release rate values of sDNA and LDNA were 5 – 20% and 4 – 13% respectively on BC300. Correlation studies and desorption experiments revealed that π-π interactions and hydrophobic forces were the primary adsorption mechanisms. Spectroscopic analyses and molecular dynamic simulation confirmed conformational changes in the adsorbed DNA but showed no chain fragmentation. These findings underscore that DNA chain length and biochar properties jointly govern the sequestration and stability of DNA, providing essential mechanistic insights for assessing the role of biochar in the persistence and mobility of genetic material in the environment.

Perfluoroocatane sulfonate (PFOS) has drawn increasing global attention due to its environmental omnipresence and adverse health effects. This study presents a synergistic strategy to address the dual challenge of legacy PFOS contamination and sustainable sewage sludge disposal by developing a novel, zinc-modified sludge-based biochar (Zn/SBC) for highly efficient PFOS removal. The innovation lies in the one-step pyrolysis using ZnCl 2 as an activator, which dramatically enhanced the specific surface area by 50-fold (to 261.33 m 2 /g) by creating a well-developed micro- and mesoporous structure. Under optimized conditions, 26%Zn/SBC exhibited a superior PFOS adsorption capacity of 60.14 mg/g, 5.83 times than that of pristine biochar, and achieved >99% removal across a wide pH range (3–11). The material exhibited remarkably stable performance, sustaining a removal efficiency over 93.6% in the presence of high concentration of competing ions and humic acid. After 5 cycles of repeated uses, 26%Zn/SBC remained highly reactive in adsorption for PFOS. In addition, the superior adsorption of PFOS by optimized 26%Zn/SBC is attributed to a unique concurrent mechanism, including electrostatic attraction facilitated by the elevated point of zero charge (pH PZC = 8.1), surface complexation with Zn/ZnO sites, π-anion interaction, and hydrophobic effects. This study not only presents a high-performance and low-cost adsorbent for PFOS remediation, which holds the potential for more cost-effective PFAS removal, but also establishes a sustainable "waste-to-wealth" strategy, paving the way for practical solutions to concentration persistent organic pollutants in aquatic environments.

Conventional solid-phase microextraction (SPME) techniques often rely on mechanical stirring devices to improve interfacial mass transfer and enhance detection sensitivity. In this study, we developed a highly sensitive bubble-driven solid-phase microextraction (BD-SPME) method that eliminates the need for mechanical stirring. This was achieved by constructing a bubble-oscillation-enhanced mass-transfer system based on a MnO 2 -loaded HLB Wax interface with high adsorption efficiency (HLB Wax @MnO 2 ). Adsorption kinetics showed that BD-SPME achieved an adsorption capacity of 1.27 μg/mg within 20 min, 1.78 times greater than that of the conventional SPME method. Isothermal adsorption curves confirmed a multilayer adsorption of capsaicin (CAP) and dihydrocapsaicin (DHC) on HLB Wax @MnO 2 . Furthermore, BD-SPME demonstrated stable performance across six types of chili peppers, with recovery rates ranging from 90.48% to 119.65% and relative standard deviations between 1.37% and 16.79%. Overall, BD-SPME overcomes the limitations of traditional stirring devices and offers a sensitive, stable, and straightforward sample pretreatment technique.

With the growing demand for eco-friendly food packaging, poly(butylene adipate-co-terephthalate) (PBAT)/polylactic acid (PLA) composite films have emerged as promising biodegradable alternatives, but their inherent limitations (e.g., poor antioxidant capacity, weak UV stability, and insufficient antimicrobial activity) hinder practical applications. This study aimed to address these drawbacks by incorporatingRosmarinus officinalisL. extract (RM) as a natural multifunctional additive. PBAT/PLA/RM blend films with RM concentrations of 0.1%, 0.3%, 0.5%, and 1% were fabricated via melt extrusion and blown film processing. Key characterizations were conducted to evaluate thermal stability, mechanical properties, morphology, antioxidant activity, UV-shielding performance, antimicrobial efficacy, and biodegradability. The results showed that RM significantly enhanced the antioxidant capacity of the films, with the highest DPPH radical scavenging activity achieved at 0.3% RM. UV-blocking performance improved incrementally with increasing RM concentration, and films containing ≥0.5% RM filtered over 90% of UVA and UVB radiation. All composite films met biodegradability standards, with over 90% degradation observed after 240 days of composting, though RM prolonged the initial degradation stage by inhibiting early microbial activity. However, the antimicrobial effect of RM was limited, and concentrations exceeding 1% caused film stickiness, impeding processing. This work demonstrates that RM is a viable natural additive for functionalizing PBAT/PLA films, offering enhanced antioxidant and UV-shielding properties while maintaining biodegradability, thus providing a promising solution for sustainable food packaging.
