    The magnetic and structural properties of oxygen deficient perovskites with composition Ba 3 Fe 2 WO 9-δ have been also systematically studied for two different oxygen contents corresponding to δ = 0.00 and δ = 0.55 in the chemical formula in order to determine and correlate their chemical composition, structural, and magnetic properties [81].The evolution of nuclear and magnetic

    Jun 20, 2019 Interacting heavy main group elements that are laden with spin–orbit coupling with transition metals, such as manganese, is a potential route toward the synthesis of new permanent magnets. In theory, this approach can be used to design magnets with large magnetic energy products by maximizing both coercive field and remnant magnetization

    Perovskites go large. Solar cells made of planar organic-inorganic perovskites now have reported efficiencies exceeding 20%. However, these values have been determined from small illuminated areas. Chen et al. used highly doped inorganic charge extraction layers to make solar cells on the 1 cm 2 scale (see the Perspective by Sessolo and Bolink)

Down-dip, the enriched layers thin to 0.2 m within about 150 m and contain 4 to 10% heavy minerals. The low-grade margins contain significant proportions of the less-dense minerals garnet

    Abstract: Despite heavy research, blue perovskite nanocrystal LEDs have struggled to match the high efficiencies of their red and green cousins, particularly at wavelengths blue enough to meet the NTSC blue standard. One of the most critical problems is the low photoluminescence yield of the nanocrystals in thin films
