Correlating Structural Disorder and Pr3+ Emission Dynamics in Lu3Al2.5–xScxGa2.5O12 Crystals: A Comprehensive Structure–Property Investigation 来源：ACS PublicationsThis study explored the influence of Sc3+ ions incorporation on the structural, vibrational, luminescent, and scintillation properties of Pr3+-doped Lu3(Al, Sc)2.5Ga2.5O12 garnet crystals. Addressing the limited research on Sc-admixed and Pr3+ doped garnet systems, this work successfully demonstrated the crystallization of garnet crystals from the melt, overcoming the substantial atomic mismatch between Sc and Al while preserving...

Prediction and Rationalization of Site Preference of Rare Earth Elements in Fluorapatite from Density Functional Theory 来源：ACS PublicationsFluorapatite (FAp, nominally Ca10(PO4)6F2) has been identified as an important host material for rare earth elements and yttrium (REY) in marine sediments. REY can be accommodated in either the larger 6+3 coordinated Ca1 site or the smaller 6+1 coordinated Ca2 site, yet little is known about the site preference of REY through the lanthanide series despite its importance for understanding REY enrichment processes in FAp. Theoretical investigations based...

Dialdehyde Chitosan/Semicarbazide Synthesis for Lanthanum, Cerium, and Neodymium Ions Recovery from Phosphate Leachate 来源:ACS PublicationsRare earth elements are among the world’s most crucial strategic minerals. Cell phones, lamp lights, televisions, wind turbines, and other contemporary electronics rely heavily on rare earth elements. As a result, this work aimed to prepare eco-friendly dialdehyde chitosan with semicarbazide (SC/DiACs), a promising method for recovering lanthanum, cerium, and neodymium from phosphate leach solution. Different analytical techniques were utilized t...
