source:TOHOKU UNIVERSITYPhotoluminescent materials are more than just the glow-in-the-dark stars your parents glued to your bedroom ceiling as a child. Photoluminescent materials are widely used in applications ranging from medical imaging to TV screens. However, improving their efficiency remains a key challenge. Researchers at Tohoku University, the Tokyo University of Science and the Indian Institute of Technology Madras have successfully enhanced the phosphorescence quantum yield of silver (Ag) clusters by utilizing the heavy atom effect--an approach which had not been fully explored in me...

Functionalized recycled polyethylene terephthalate plastic by rare earth oxide for electronic device and housing infrastructure applications source:scientific repoetsRecycled polyethylene terephthalate (RPET) was doped with Neodymium Oxide (Nd2O3: 0, 1, 2, 4, and 8 wt.%) to investigate its structural, optical, dielectric, and mechanical properties. X-ray diffraction (XRD) analysis revealed that pure RPET exhibited an amorphous structure, while the incorporation ofNd2O3 induced the formation of crystalline phases, with crystallinity increasing as the Nd2O3 concentration increased. Fourier-...

source:ACS PublicationsA novel synthetic route to the triple-decker benzene tetra-anion complexes [(η5-C5iPr5)M(μ:η6:η6-C6H6)M(η5-C5iPr5)] is reported for a range of early and late rare-earth elements, i.e., M = Y, La, Sm, Gd, and Dy (1M). The lanthanum complex 1La is the first benzene tetra-anion complex of the largest rare-earth element. Aromaticity in the 10π-electron benzene ligands is confirmed through crystallographic studies of all compounds and nucleus-independent chemical shift calculations on 1Y and 1La. Analysis of the bonding in 1Y and 1La using density functional theory revealed s...
