来源：ACS PublicationsAlkaline hydrogen oxidation reaction (HOR) is the bottleneck restricting the performance of anion-exchange membrane fuel cells (AEMFCs), originating from sluggish Volmer kinetics induced by mismatched adsorption of H* and OH intermediates on commercial Pt/C catalysts, accompanied by high Pt cost, poor durability and inferior CO tolerance. Herein, Pr-doped PtMo ternary nanoparticles anchored on XC-72 carbon (PtMoPr/C) are fabricated via a facile wet chemical reduction strategy, where trace Pr dopant regulates electronic configuration and lattice strain of PtMo via unique 4f-5...

来源：ACS PublicationsRare-earth ions are pivotal for integrated photonic light sources, but their low optical transition cross sections inherently limit pump absorption efficiency and spontaneous emission rates. Here, we overcome these drawbacks by designing a dielectric metasurface that supports dual flat bands, which synergistically enhance both excitation and emission processes. Strong momentum–space anticrossings arise from hybridization between transverse-electric-like and transverse-magnetic-like surface lattice resonances hosted by a TiO2 nanodisk array integrated on a Yb3+-doped Ta2O5 sl...

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...
