来源：ACS PublicationsThe production of energy-efficient technologies and advanced electronics requires high-purity critical minerals, such as individually separated rare earth elements (REEs). Chemical REE separation processes rely on small differences in physicochemical properties (i.e., ionic charge and radii) to transport selective metal ions across liquid–liquid interfaces, making selective separation time-consuming and expensive. Incorporating another intrinsic property, ionic magnetic moment, alongside ionic radius may improve interfacial transport. We report here a novel batch solvent ext...

来源：ACS PublicationsSkin wounds usually cause delayed wound healing or infection due to the invasion of microorganisms, which seriously endangers human life and health. In the process of first aid and treatment, antibacterial dressings are usually used to achieve high efficiency in inhibiting infection and promoting wound healing. However, because of the widespread use of antibiotics or low-activity antibacterial ingredients in dressing fillers, research on dressing fillers is imminent. Here, we propose a preparation method for a high-performance dressing filler based on Y-based MOFs. Ag+ was a...

来源: ACS PublicationsThe effects and mechanisms of preconception couples’ coexposure to rare earth elements (REEs)─emerging reproductive toxicants─on spontaneous abortion (SA) remain unclear. This nested case–control study included 326 SA couples and 326 matched controls from a multicenter preconception cohort in Anhui Province (2019–2021). Eight REEs and eight oxidative stress biomarkers (OSBs) were measured in preconception urine. Conditional logistic regression found that urinary concentrations of lanthanum, cerium, praseodymium, neodymium, and samarium in females and males were associated w...

来源：ACS PublicationsMonodisperse oxide nanoparticles have attracted attention for biomedical applications. However, conventional synthetic methods often provide limited control over particle size, morphology, and polydispersity. Herein, we report a bottom-up strategy for synthesizing hollow rare-earth silicate nanospheres based on the Kirkendall effect. The addition of an optimized amount of 1-propanol to the reaction medium altered the dielectric constant and surface tension, thereby increasing the nucleation rate and reducing the precursor size. During high-temperature treatment, unequal inte...
