来源:ACS PublicationsRare-earth elements (REEs) are critical to multiple areas in clean energy technology, including magnets, catalysts, as well as lighting and electronic products. With the growing awareness for sustainable mining and recycling, electrochemical approaches have emerged as a promising pathway for the energy-efficient and green recovery of rare-earth elements, including processes for extraction, concentration, purification, and utilization. In this paper, we review electrochemical pathways for the recovery of REEs from mining and unconventional feedstocks, including coal mining by...

Strain-Driven Oxygen Vacancy Ordering in LaNiO₃ Thin Films Revealed by Integrated Differential Phase Contrast Imaging in Scanning Transmission Electron Microscopy来源:Royal Society Of ChemistryRare-earth nickelates, such as LaNiO3 (LNO), exhibit complex electronic properties, with ordered oxygen vacancies (OOV) influencing conductivity and magnetic behavior. We investigate the structural stability of strain-induced OOV phase in LNO thin film grown on SrTiO3 substrate and impact of Ruddlesden-Popper (RP) faults. Using high-angle annular dark-field scanning transmission electron microscopy (HAADF-...

来源:ACS PublicationsThe growth of high-entropy alloy (HEA) thin films using the molecular beam epitaxy (MBE) technique widens our horizons in materials design. This technique offers precise control of key parameters (deposition rate, substrate orientation, interfacial, or lattice strain), and it becomes possible to study the interplay existing between the elemental choice, their respective stoichiometry, and the associated physical and chemical properties. Such fine-tuning of HEA with an immense compositional space will bring additional advanced materials with exotic properties. Here, we report...
