Effect and mechanism of the moisture content on the kinetic retardation of LNAPL pollutant migration by the capillary zone.

Light nonaqueous-phase liquids (LNAPLs) are the main source of organic pollution in soil and groundwater environments. The capillary zone, with varying moisture contents, is the last barrier against the infiltration of LNAPL pollutants into groundwater and plays an important role in their migration and transformation. However, the effect and mechanism of the moisture content in the capillary zone on LNAPL pollutant migration are still unclear.

In Situ Anchoring Functional Molecules to Polymer Chains Through Supramolecular Interactions for a Robust and Self-Healing Multifunctional Waterborne Polyurethane.

Nowadays, much attention is paid to the development of high-performance and multifunctional materials, but it is still a great challenge to obtain polymer materials with high mechanical properties, high self-healing properties, and multifunctionality in one. Herein, an innovative strategy is proposed to obtain a satisfactory waterborne polyurethane (PMWPU-Bx) by in situ anchoring 3-aminophenylboronic acid (3-APBA) in a pyrene-capped waterborne polyurethane (PMWPU) via supramolecular interactions. The multiple functional sites inherent in 3-APBA can produce supramolecular interactions with groups on PMWPU, promoting the aggregation of hard domains in the polymer network, which confers the PMWPU-Bx strength (7.

Application of artificial intelligence in the health management of chronic disease: bibliometric analysis.

Background: With the rising global burden of chronic diseases, traditional health management models are encountering significant challenges. The integration of artificial intelligence (AI) into chronic disease management has enhanced patient care efficiency, optimized treatment strategies, and reduced healthcare costs, providing innovative solutions in this field. However, current research remains fragmented and lacks systematic, comprehensive analysis.

Modulating room-temperature phosphorescence of D-π-A luminogens via methyl substitution, positional isomerism, and host-guest doping.

Organic room-temperature phosphorescence (RTP) luminogens have showed significant potential in the fields of diagnostics, sensing, and information encryption. However, it is difficult to achieve high RTP yield (Φ) and long RTP lifetime simultaneously. By methyl substitution, positional isomerism, and host-guest doping, three new D-π-A type luminogens named as TBTDA, 2M-TBTDA, and 3M-TBTDA were designed and synthesized, whose RTP properties were tuned and optimized.

Predictive Model for Histological Chorioamnionitis Risk in Parturients with Intrapartum Fever.

This study aimed to analyze the causative factors of histological chorioamnionitis (HCA) in parturients with intrapartum fever, assess the implications for maternal and neonatal outcomes, and develop a predictive model to enhance clinical decision-making. A retrospective analysis was performed on 408 parturients with intrapartum fever at Fujian Provincial Maternal and Child Health Hospital from January 2022 to June 2023. Based on post-delivery placental pathology, the data were categorized into HCA (249 cases) and non-HCA groups (159 cases).
