source: Waseda UniversityCopper-oxide (CuO2) superconductors, such as Bi2Sr2CaCu2O8+δ (Bi2212), have unusually high critical temperatures. Optical reflectivity measurements of Bi2212 have shown that it exhibits strong optical anisotropy. However, this has not been studied through optical transmittance measurements, which can offer more direct insights into bulk properties.Now, researchers have elucidated the origin of this optical anisotropy through ultraviolet and visible light transmittance measurements of lead-doped Bi2212 single crystals, enabling a more precise investigation into its supe...

Developing highly efficient recovery materials for precious 'rare earth metals' and improving resource circulation for digital infrastructure source:eurekalertKorea imports 95% of its core minerals such as lithium, nickel, and rare earths. Rare earths, in particular, are characterized by chemical, electrical, magnetic, and luminescent properties that can be achieved by adding only a small amount, and their use has recently increased significantly as core materials in the eco-friendly automobile and renewable energy industries. China, a major producer of rare me...
