The co-contamination of V(Ⅴ) and Cr(Ⅵ) in wastewater poses significant risks to aquatic ecosystems and human health. However, it remains challenging to both develop efficient adsorbents for their simultaneous removal and elucidate their interactions. In this study, a novel metal-organic framework (MOFs) adsorbent, UiO-66-NH₂, was synthesized in an open system at atmospheric pressure for the treatment of combined pollution of V(Ⅴ) and Cr(Ⅵ) in solution. Adsorption experiments demonstrated that UiO-66-NH 2 exhibits strong adsorption capacity toward V(V) and Cr(VI), primarily governed by chemisorption. The maximum adsorption capacities for V(V) and Cr(VI) in single system adsorption were 543.40 mg/g and 335.28 mg/g, respectively. In the binary system, V(V) and Cr(VI) adsorption capacities reached 712 mg/g and 501 mg/g, respectively, which were 1.92 and 3.32 times those in their respective single systems. This confirms synergistic effects. However, localized uptake fluctuations, such as a 4.4% decrease in Cr uptake with increasing V concentration, indicate competitive interactions. The material also showed selective adsorption toward V(V). Combined with material characterization and molecular dynamics (MD) simulations, the chemical composition and structural stability of the material were analyzed, and the adsorption mechanism at the micro level was revealed. The adsorption mechanism of UiO-66-NH 2 for V(V) and Cr(VI) involves electrostatic interactions, chemical reduction, hydrogen bonding, and coordination. These findings provide theoretical insights for the application of UiO-66-NH 2 in treating V(V) and Cr(VI) contaminants in wastewater and for the design of related adsorbents.

A novel hybrid-shell phase change materials (PCMs) was prepared via Pickering emulsion polymerization, exhibiting high thermal stability while maintaining a high latent heat. Using n-octadecane as the core, microencapsulated phase change materials (MicroPCMs) with PMMA@PS@SiO 2 hybrid shells were designed. The MicroPCMs achieved an enthalpy of 119.2 J/g, reaching 99.3% of the theoretical value, with an energy storage efficiency of 66.1% and a heat storage capacity of 99.8%. The temperature corresponding to 5% weight loss ( T 5% ) increased by 83 ℃, and the leakage rate remained as low as 5.6% after 200 cycles. The formation of the hybrid shell significantly enhanced the thermal stability and cycling durability of the MicroPCMs, while maintaining a high heat storage capacity and effectively addressing the leakage and cycling instability commonly existing in PCMs. Moreover, the surface-modified SiO 2 acted as a stabilizer to construct the Pickering emulsion template, enabling a green fabrication process. Finally, flexible PCM films were fabricated by melt blending and extrusion of MicroPCMs and poly(vinyl alcohol) (PVA), exhibiting excellent thermal management performance. Overall, the MicroPCMs demonstrate significant potential, with particular relevance and advantages in high-temperature processing areas.

Ethylene (C 2 H 4 ), a natural plant hormone, accelerates the ripening and senescence of fruits and vegetables (F&V), posing significant challenges to their post-harvest preservation. Herein, we develop a C 2 H 4 scavenging nanofiber membrane by chemically modifying zein (ZN) with (3-mercaptopropyl) triethoxysilane (MPTES). This modification reduces the hydroxyl content while introducing sulfhydryl groups on zein chain. The typical membrane of ZN-MPTES3 demonstrates excellent hydrophobic property with a water contact angle (WCA) of > 140°, and can maintain structural integrity after 24 h of water immersion. Additionally, the MPTES grafting enhances the membrane's roughness. At 25 °C, the ZN-MPTES3 membrane effectively extends the shelf-life of bananas through a thiol-ene click reaction with C 2 H 4 , which is accelerated under UV exposure (365 nm), further enhancing the preservation efficacy. These results demonstrate the potential of the ZN-MPTES electrospun membrane as a sustainable and effective platform for the preservation of post-harvest F&V.

Electronic-grade propylene glycol monomethyl ether acetate (PGMEA) plays a vital role in the semiconductor industry. The direct synthesis of PGMEA from propylene glycol monomethyl ether (PM) and acetic acid (HAC) is inherently limited by reaction equilibrium constraints. The reactive distillation (RD) process effectively addresses this equilibrium limitation by utilizing an entrainer to continuously remove reaction products from the system. A significant enhancement in reaction conversion is achieved through this approach. In the reactive distillation process, PM, as one of the reactants, is utilized as the water-entraining agent, which enables simultaneous promotion of the forward reaction via water removal and prevention of impurity introduction, as no external entrainer is required. At the beginning, the reaction kinetics model for PGMEA synthesis is established to precisely elucidate the influence of temperature and concentration on the progress. Furthermore, reactive distillation experiments and process simulation studies are conducted, and two highly feasible and broadly applicable processes for high-purity PGMEA production are yielded ultimately. Through the study, a high-purity PGMEA product is provided as distillation feedstock for subsequent purification steps to achieve electronic-grade product specifications.

The pervasive contamination of tetrabromobisphenol A (TBBPA) presents a critical environmental challenge due to its persistence and resistance to conventional degradation. Although sulfidized nanoscale zero-valent iron (S-nZVI) represents a promising remediation avenue, its efficacy is severely constrained by particle agglomeration and insufficient mineralization capabilities. Here, we report a self-dissociation-assembly strategy to engineer a robust S-nZVI composite supported on Mg Al layered double oxides (S-nZVI@LDO) for the substantial removal of TBBPA. By modulating the precursor synthesis pathways, we demonstrate that the hydrothermal-derived LDO support (α-phase) creates a unique nanosheet architecture that facilitates superior dispersion of reactive Fe/S species compared to chemically precipitated counterparts. The optimized S-nZVI@LDO α composite achieves >95% TBBPA removal efficiency, with a debromination efficiency of 71% and a mineralization rate of 51%, significantly outperforming traditional composites. Mechanistic investigations reveal a synergistic pathway involving rapid electrostatic adsorption, reductive debromination driven by surface-bound Fe 0 , and oxidative mineralization via in-situ generated radicals. Furthermore, the catalyst exhibits improved stability and reusability over multiple cycles. This work elucidates the critical role of precursor structural evolution in catalyst design and provides a scalable, high-efficiency solution for the remediation of halogenated organic pollutants.

In this study, we developed catechol-imprinted magnetic molecularly imprinted polymers (Ca-DFFPBA-MMIPs) via a dual-affinity strategy combining boronate affinity and a two-step template immobilization protocol. The Ca-DFFPBA-MMIPs exhibited high affinity and selectivity for catecholamines (norepinephrine, epinephrine, and dopamine) under neutral conditions. The adsorption capacity reached a plateau at pH 6.5–7.0, and the adsorption time was optimized to 40 minutes. The MMIPs showed excellent selectivity for the target catecholamines over structurally related interferents. The Ca-DFFPBA-MMIPs also demonstrated good reusability, retaining ≥90% of their initial adsorption capacity after seven consecutive cycles. The analytical performance of the Ca-DFFPBA-MMIPs was validated in terms of linear range, coefficient of determination (R²), limit of detection (LOD), limit of quantification (LOQ), and intra- and inter-day precision (RSD). The LODs were 12–31 ng mL⁻¹ and LOQs were 40–103 ng mL⁻¹, with RSDs of 0.87–1.13% (intra-day) and 1.75–1.95% (inter-day). The Ca-DFFPBA-MMIPs were successfully applied to the selective extraction of catecholamines from equine urine (enrichment factors of 18–27), with recoveries ranging from 64.5% to 105.7%. This study provides a new approach for the analysis of catecholamines in complex matrices and highlights the potential of Ca-DFFPBA-MMIPs as a practical nanosorbent for efficient and selective enrichment of catecholamines and related compounds.

Covalent organic frameworks (COFs) with long-range ordered periodic structures have emerged as promising photocatalysts for advanced oxidation processes. Herein, we reported a highly crystalline porphyrin-based COF (COF-TAP-Cu) featuring outstanding visible-light-driven oxidation activity. COF-TAP-Cu was obtained via a facile bottom-up metallization strategy that tuned the conjugation and planarity of the porphyrin building block (TAP-H). Incorporation of Ni 2+ or Cu 2+ into TAP-H moderately enhanced the π-conjugation of the resulting metalloporphyrin monomers (TAP-M; M = Ni, Cu), leading to markedly improved crystallinity of the corresponding COFs. Notably, structural analysis indicated that the porphyrin ring in TAP-Ni undergoes pronounced distortion, whereas TAP-Cu retained a near-planar geometry. As a result, COF-TAP-Cu exhibited higher crystallinity and superior photocatalytic oxidation performance compared with the metal-free porphyrin-based COFs (COF-TAP-H) and Ni-anchored porphyrin-based COFs (COF-TAP-Ni). Under visible-light irradiation, COF-TAP-Cu efficiently activated molecular oxygen to produce both O 2 •- ( via electron transfer) and 1 O 2 ( via energy transfer), enabling rapid degradation of sulfadiazine (SDZ) with a removal efficiency of up to 95% within 30 min. This work highlighted a monomer-design strategy that balanced conjugation and planarity to construct highly crystalline porphyrin-based COFs, offering new insights for photocatalytic antibiotic remediation in aquatic environments.

Al 2 O 3 -ZrO 2 biphasic fibers were of considerable interest due to their superior mechanical properties and thermal stability. Despite this, precise control over fiber structure and further enhancement of thermal stability remained significant challenges. This study investigated the regulation of phase transformation behavior and thermal stability in Al 2 O 3 -ZrO 2 fibers through Sc 2 O 3 doping. The findings demonstrated that Sc 2 O 3 doping facilitated the formation of α-Al 2 O 3 and t-ZrO 2 phases within the fibers. In samples containing 1 wt.% Sc 2 O 3 , the average crystal size of α-Al 2 O 3 was 160 nm, while t-ZrO 2 crystals displayed a bimodal nanoscale distribution. The Weibull strength of these fibers reached 1.99 GPa. Following exposure to 1200 °C for 100 h, most α-Al 2 O 3 crystal sizes remained within the 200-300 nm range. The mechanism by which Sc 2 O 3 doping affects structural evolution and enhances the thermal stability of Al 2 O 3 -ZrO 2 fibers was also examined.

Covalent organic frameworks (COFs) are promising photocatalysts for hydrogen peroxide (H 2 O 2 ) production, yet their rational design remains challenging. Although machine learning has advanced the prediction of properties of porous materials, its application to COF-based photocatalysis faces two major challenges: the representation of multilevel structural features and the limited availability of training datasets. Here we present a comprehensive computational framework, termed ‘information co-evolution’, that accelerates the discovery of efficient COF structures for H 2 O 2 photosynthesis. This framework integrates two pathways: to mitigate data limitations, we introduce data augmentation techniques and ensemble modelling; concurrently, to address the structural encoding challenge, we introduce a cross-level feature fusion strategy that integrates these fragment descriptors with mechanism-driven physical descriptors. These strategies collectively reduced the validation root mean square error from 4.70 to 3.31. Among over 10,000 candidates, our framework can successfully identify high-performance COFs for H 2 O 2 photosynthesis, for example, COF-343 achieves a H 2 O 2 photosynthetic rate of 12,978.7 μmol h −1 g −1 . The model interpretation further unveiled critical structural motifs, offering information for the rational design of COF photocatalysts beyond traditional trial-and-error methods.

Although massive cell atlases are already available, it is still a challenge to obtain an atlas of all tissues within a single body, especially in fetuses and pregnant mothers. We present a transcriptomic atlas of 2.56 million single cells covering 115 and 119 tissues from one fetal pig and its pregnant mother, respectively. We found that a cluster of heart capillary endothelial cells with enhanced fatty acid transit capability was enriched for pregnancy but restored after gestation. We also deciphered that l -leucine transport insufficiency in the trophoblast causes fetal growth restriction by reducing a muscle type II myofiber subcluster. Our “all-from-one” strategy enabled the identification of tissue cell type–specific transcription factors and provided insights into pregnancy heart adaptation and fetal growth restriction.

Downward solar evaporation with multistage configurations is a promising off-grid solution for high-efficiency potable water production. However, a major, yet often overlooked, barrier to practical application is the significant, unquantified performance gap between laboratory benchmarks and field operation, arising from the complex environmental factors. To diagnose this gap, this work first introduces the Environmental Robustness Index (ERI), the ratio of field-to-lab normalized water productivity ( P’ ), as an essential metric. A comprehensive framework is then developed to precisely quantify the effect of key environmental factors, including wind, sky cooling, and ambient temperature, on the ERI. Guided by the framework, we present the spectrally selective air lock strategy as a universal principle to suppress environmental heat losses and improve ERIs. Implementing this strategy significantly enhances downward solar evaporator’s ERIs from 0.55 to 0.98, effectively closing the gap. This study establishes a framework for solar evaporation to move beyond reporting P’ lab alone and utilize ( P’ lab , ERI) as the dual metrics for advancing real-world applicability.
