Plus de détailsRare earth elements (REEs) are well known tracers of geochemical processes that are also preferentially incorporated into phosphates, which is why they are often used to reconstruct the paleoenvironmental conditions that persisted during the formation of marine authigenic and biogenic phosphates (Grandjean and Albarède, 1989, Grandjean ...

Plus de détailsRare earth ions (Eu3+ and Nd3+) doped BaSnF4: transport and photoluminescence characteristics. Investigation on the X-ray diffraction results of rare earth ions such as Eu3+ and Nd3+ doped BaSnF4 materials indicates that the doped materials show a similar pattern of BaSnF4 with the same tetragonal structure (P-4/nmm).
Plus de détails[en] Investigation has been made of the transport of rare-earth elements through liquid extraction membranes which are Dacron nuclear filters impregnated with various kinds of extractants. It has been found that in systems with the extractant-carriers tri-n-octylamine and di-2-ethylhexylphosphoric acid a reversal occurs of the dependences of the flow rates and distribution coefficients on the ...

Plus de détailsRare-earth elements (REEs) are known to be a group of emerging pollutants, but the geochemistry of REEs in river waters in ion-adsorption rare-earth mining areas has attracted little attention. In this study, samples of the <0.45 μm and 0.22–0.45 μm (large colloids) water fractions and acid-soluble particles (ASPs) were collected from a ...
Plus de détailsInterfacial engineering strategy is an efficient route for improving carrier extraction and transport in planar heterojunction PSCs. Herein, we use the rare earth (RE)-doped WOx nanorods/SnO2 hybrid films as the electron transport layer (ETL) to accurately modulate the interfacial charge dynamics for hysteresis-free, high-performance devices.
