Harnessing Dynamic Supramolecular Interactions for Lanthanide Detection via Computational Pattern Recognition of Magnetic Resonance Fingerprints 来源: ACS PublicationsThe reliance of modern technology growth on lanthanides presents dual challenges: securing sustainable sources from natural or recycled materials and reducing environmental harm from waste discharge. However, the similar ionic radii, oxidation states, and binding affinities of Ln3+ ions hinder their nondestructive detection in mixtures. Furthermore, the overlap of spectroscopic signals and the inapplicability for opaque soluti...

来源：ACS PublicationsWater scarcity and the presence of contaminants of emerging concern (CECs), such as antibiotics, pose significant challenges to sustainable agriculture and public health. In this study, we synthesized and characterized lanthanide-doped zinc oxide (ZnO) photocatalysts (specifically with erbium and ytterbium) to enhance the degradation of sulfamethoxazole (SMX) in wastewater. Utilizing a sol–gel hydrothermal method, we produced various doped ZnO samples and assessed their photocatalytic activity under UV irradiation. The synthesized materials were characterized by powder X-ray...

来源:ACS PublicationsOptically addressable spin impurities in crystals along with device engineering provide an attractive route to realizing quantum technologies in the solid state, but reconciling disparate emitter and host material constraints for a given target application is often challenging. Rare-earth ions in two-dimensional (2D) materials could mitigate this problem given the atomic-like transitions of the emitters and the versatile nature of van der Waals systems. Here we combine ion implantation, confocal microscopy, and ab initio calculations to examine the photon emission of Er-dope...

Dynamic Competition between Hubbard and Superexchange Interactions Selectively Localizes Electrons and Holes through Polarons 来源：ACS PublicationsControlling the effects of photoexcited polarons in transition metal oxides can enable the long time-scale charge separation necessary for renewable energy applications and controlling new quantum phases through dynamically tunable electron–phonon coupling. In previously studied transition metal oxides, polaron formation is facilitated by a photoexcited ligand-to-metal charge transfer (LMCT). When the polaron is formed, oxygen atoms move away fro...
