Phytogenic Self-Conducting Flash Joule Heating Converts Rare-Earth Hyperaccumulator Biomass into Graphene Composites with Minimized Life-Cycle Impacts来源：ACS PublicationsRare-earth elements (REEs) are essential to clean-energy technologies, yet their extraction remains energy intensive and environmentally damaging. Although REE hyperaccumulator plants offer sustainable bioresource, their conversion into functional materials is inefficient and poorly developed. Here, we report a feedstock-customized phytogenic self-conducting flash Joule heating (PSC-FJH) strategy that directly converts REE hype...

来源：ACS PublicationsPolyoxometalate (POM) anions serve as templates for constructing high-nuclearity silver nanoclusters. Utilizing rare-earth-containing POMs, particularly metastable Silverton-type architectures, remains a synthetic challenge. Herein, a rare-earth-driven in situ core evolution strategy is reported for the construction of a high-nuclearity silver cluster. By introducing dysprosium nitrate, the assembly pathway was redirected from the octamolybdate-templated [Mo8O28@Ag48(CyhS)24(CF3COO)16(CH3CN)4]·5DMF (Mo8@Ag48, CyhS = cyclohexanethiolate) baseline to yield a Silverton-tem...

来源：ACS PublicationsSpinel-type Zn2SnO4 and its La- and Ce-modified variants were synthesized via a solid-state route to investigate aliovalent substitution–induced structural, optical, and photoluminescence (PL) modulation. Undoped, La- and Ce-doped Zn2SnO4 samples were characterized using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, ultraviolet–visible spectroscopy, photoluminescence, scanning electron microscopy (SEM)–energy-dispersed spectroscopy (EDS), and X-ray photoelectron spectroscopy (XPS) techniques. XRD confirmed the dominant cubic spi...

来源：ACS PublicationsThe development of innovative luminescent materials for lighting and display applications is an important research field. In this work, we have employed an anionic condensation approach to discover a novel oxonitridosilicate synthesized via Li metal flux. LaSi2N3O crystallizes in the orthorhombic space group Pna21 (a = 7.82609(6), b = 18.24908(15), and c = 4.86567(5) Å) with a structure consisting of [Si6N12O2] ribbons cross-linked by [SiN3O] tetrahedra. This follows previously reported structural rules for a series of condensed rare-earth oxonitridosilicates, and disco...
