ConspectusChiral metal-organic frameworks (MOFs) are promising candidates as luminescent sensing materials for chiral species, which essential components in modern industries, pharmaceuticals, and biological processes. The discrimination of enantiomers with highly similar physical chemical properties is crucial because they often present concurrently the same system but may feature distinct effects on living matters. While rapid precise capabilities MOFs outshine traditional detection methods species daily life, production, natural environment, it requires well-matched electronic structures between species. Yet, conventional strategies to construct immensely challenging due crystallization difficulties based low-symmetric building blocks.Recent advancements MOF chemistry have led novel pathways synthesizing enantioselective sensing. Compared direct synthesis using optically pure ligands, usually complex costly, indirect has garnered significant attention reduced costs, simplified synthesis, enhanced material stability, broad application scope. In past few years, our group developed guest ion exchange, coordination modification, defect engineering indirectly MOFs. exchange cost-effective introducing ions into pores can be applied only charged frameworks. addition, also faces limitations availability tendency toward chirality loss during process.

Organic pollutants like per- and polyfluoroalkyl substances (PFASs) exhibit persistence, bioaccumulation, resistance to degradation, high toxicity, garnering significant attention from scholars worldwide. To better address mitigate the environmental risks posed by PFASs, this paper employs bibliometric analysis examine literature on PFASs' concentrations collected in Web of Science (WoS) database between 2019 2024. The results show that overall trend pollution research is relatively stable increasing. In addition, study also summarizes status traditional PFASs across different media typical freshwater basins. It analyzes surface water, sediment, aquatic organisms, elucidating their distribution characteristics potential sources. While perfluorooctanoic acid (PFOA) perfluorooctane sulfonic (PFOS) levels water environments are declining annually, short-chain substitutes emerging as primary pollutants. Short-chain frequently detected whereas long-chain tend accumulate sediments. more likely concentrate protein-rich organs tissues. presence largely influenced human activities, such metal plating, fluoride industry development, industrial wastewater discharge. Currently, development China faces a complex dilemma, entangled policy legal constraints, production demands, use new alternatives, regulation restriction, creating vicious cycle. Breaking deadlock necessitates continuous active scientific particularly PFOS, with an emphasis detailed investigations sources sinks. Furthermore, ecological health risk assessments were conducted using Risk Quotient (RQ) Hazard (HQ) methods. Comprehensive comparison indicates (such PFOA) majority basins at low-risk level (RQ < 0.1 or HQ 0.2), PFOS some medium-risk (0.1 RQ 1), no basin high-risk level. adsorption removal approaches analyzed, revealing combination multiple treatment technologies novel integrated technology holds excellent prospects for PFASs.

Perfluorooctanoic acid (PFOA) is a highly recalcitrant organic pollutant, and its bioaccumulation severely endangers human health. While various methods are developed for PFOA removal, the targeted design of adsorbents with high efficiency reusability remains largely unexplored. Here rational synthesis two novel zirconium-based metal‒organic frameworks (MOFs) bearing free ortho-hydroxy sites, namely noninterpenetrated PCN-1001 twofold interpenetrated PCN-1002, presented. Single crystal analysis pure ligand reveals that intramolecular hydrogen bonding plays pivotal role in directing formation MOFs hydroxy groups. Furthermore, transformation from to PCN-1002 realized.

Anode-free Li-metal battery (AFLMB) is being developed as the next generation of advanced energy storage devices. However, low plating and stripping reversibility Li on Cu foil prevents its widespread application. A promising avenue for further improvement to enhance lithophilicity foils optimise their surfaces through a metal-organic framework (MOF) functional layer. excessive binder usage in current approaches obscures active plane MOF, severely limiting performance. In response this challenge, MOF polycrystalline membrane technology has been integrated into field AFLMB work. The dense seamless HKUST-1 was deposited (HKUST-1 M@Cu) via an epitaxial growth strategy. contrast traditional layers, binder-free fully exposes lithophilic sites, effectively reducing nucleation overpotential optimising deposition quality Li. Consequently, layer becomes denser, eliminating effects dendrites. When coupled with LiFePO

Abstract The confluence of pervasiveness, bioaccumulation, and toxicity in freshwater contaminants presents an environmental threat second to none. Exemplifying this trifecta, per‐ polyfluoroalkyl substances (PFAS) present alarming hazard among the emerging contaminants.
