Summary: To reduce environmental impact and cut costs, the development of recyclable and green heterogeneous catalysts is extremely important. In this research, a core-shell magnetic structure consisting of Fe3O4 and a microporous organic network (MON) was successfully developed, and palladium nanoparticles (NPs) were physically absorbed onto the outer surface of the shell substance. Various analyses confirmed the effective bonding between Pd NPs and the MON materials, and the immobilization of the palladium NPs. The prepared nanoheterogeneous catalysts exhibited excellent catalytic performance in mild conditions for C-C formation.

Summary: The use of microporous organic networks (MONs) as stationary phases in gas chromatography (GC) shows great potential in achieving good resolution for position isomers and hydrocarbons. A novel covalent coupling strategy allows for the fabrication of uniform MONs bonded capillary columns with excellent lifetime, precision, and resolution, outperforming commercial capillary columns for the separation of chlorotoluene and bromotoluene position isomers. This study highlights the feasibility and potential of using MONs in separation science.

Summary: This study establishes design principles for noncovalent surface functionalization, which successfully renders microporous nanocrystals with dry, gas-accessible pores dispersible in water and enhances their hydrolytic stability. Block co-polymers with persistence lengths that exceed the micropore aperture size of zeolitic imidazolate frameworks (ZIFs) significantly enhance dispersibility and stability while preserving porosity and >80% of the theoretical O2 carrying capacity. Strong bonds between the polymer and exposed metal sites on the external particle surface contribute to the greatest improvements in hydrolytic stability. These findings provide guidelines for controlling the interface between polymers and metal-organic framework particles in aqueous environments to enhance the properties of microporous water.

Summary: Nanogenerators (NGs) are a potential technology for self-powered systems and portable electronics in the Internet of Things generation. They convert mechanical motion into electrical signals and have evolved since their discovery in 2006 and 2012. Crystalline porous materials (CPMs) such as metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) have been widely studied as efficient material options for NGs due to their special properties.

Summary: Thermoresponsive diblock copolymers were successfully synthesized and utilized in palladium-catalyzed coupling reactions in water. The study demonstrated higher efficiency in extraction for PDEAAm copolymers compared to PNIPAAm copolymers. Furthermore, aggregative precipitation of products in Sonogashira coupling reactions was observed, and washing the precipitate with water resulted in high purity products with good yields.

Summary: This study aims to accurately assess the environmental risk of organic contaminants (OCs) in an internationally important coastal wetland and identify compounds of concern and their potential sources and risk factors. The results revealed the presence of various pesticides, pharmaceuticals and personal care products, per and polyfluoroalkyl substances (PFASs), and organophosphorus flame retardants (OPFRs) in the wetland. Some compounds were detected for the first time in this area. Spatial distribution analysis showed higher pesticide concentrations in the northern part of the wetland, and ibuprofen was identified as a compound of concern. The sampling approach used in this study shows promise as a risk assessment tool for understanding the transport and fate of OCs in protected areas.
