来源：ACS PublicationsThe detection of per- and polyfluoroalkyl substances (PFASs) in the environment is critical due to their adverse health effects, but it remains challenging because of the high cost and technical complexity of standard analytical methods. We developed a series of rare earth-based bimetallic metal–organic frameworks (MOFs) for the sensitive and efficient fluorescence detection of perfluorooctanoic acid (PFOA). By systematically modulating the ligand functional groups with amino (−NH2), hydroxyl (−OH), and fluorine (–F) moieties, the influence of ligand electronegativity on the...

来源：ACS PublicationsRare-earth elements (REEs) are critical for medical technologies, electronics, and clean energy. Coal fly ash (CFA), a byproduct of coal combustion, offers a promising alternative REE source. However, efficient extraction and separation of REEs from CFA remain challenging due to the complex composition of CFA. This study introduces a sustainable method for REE recovery using a recyclable ionic liquid, betainium bis(trifluoromethylsulfonyl)imide ([Hbet][Tf2N]), which serves both as the extractant from CFA and as the electrolyte in electrodeposition. In the first stage, [Hbet]...

Phytogenic Self-Conducting Flash Joule Heating Converts Rare-Earth Hyperaccumulator Biomass into Graphene Composites with Minimized Life-Cycle Impacts来源：ACS PublicationsRare-earth elements (REEs) are essential to clean-energy technologies, yet their extraction remains energy intensive and environmentally damaging. Although REE hyperaccumulator plants offer sustainable bioresource, their conversion into functional materials is inefficient and poorly developed. Here, we report a feedstock-customized phytogenic self-conducting flash Joule heating (PSC-FJH) strategy that directly converts REE hype...

来源：ACS PublicationsPolyoxometalate (POM) anions serve as templates for constructing high-nuclearity silver nanoclusters. Utilizing rare-earth-containing POMs, particularly metastable Silverton-type architectures, remains a synthetic challenge. Herein, a rare-earth-driven in situ core evolution strategy is reported for the construction of a high-nuclearity silver cluster. By introducing dysprosium nitrate, the assembly pathway was redirected from the octamolybdate-templated [Mo8O28@Ag48(CyhS)24(CF3COO)16(CH3CN)4]·5DMF (Mo8@Ag48, CyhS = cyclohexanethiolate) baseline to yield a Silverton-tem...
