来源：ACS PublicationsOrganic dyes are commonly used in the textile and leather industries and are frequently detected in natural water bodies, posing potential hazards to the ecological environment and human health. Sulfate-radical-based advanced oxidation processes (SR-AOPs) possess strong oxidation capabilities and wide pH applicability and are widely used to treat organic dyes in wastewater. Designing a green, safe, and stable photocatalytic composite SR-AOP system remains a challenge. In this study, two new rare earth (RE)-based metal–organic framework (RE-MOF) photocatalysts (M-MOFs, where ...

来源：ACS PublicationsHigh-pressure synthesis provides unique pathways to materials with unprecedented structures and properties. Here we report the synthesis and structural characterization of novel rare-earth (La, Sm, Gd, Dy) chlorides, chloride carbides, and oxychloride phases obtained due to complex chemical reactions in diamond anvil cells after laser heating of rare-earth metals and NaCl at pressures of 39–127 GPa and temperatures of 2500–2800 K. Synchrotron single-crystal X-ray diffraction analysis allowed us to solve previously unknown crystal structures of binary (La2Cl, LaCl, LaCl3, DyC...

来源：ACS PublicationsMIREIII-based nitrate-bridged double perovskite-type hybrid materials are an emerging class of multifunctional materials that exhibit intriguing physical properties. While the synthesis and structural phase transitions of these compounds, including (TMA)2NaPr(NO3)6 (TMA+ = tetramethylammonium cation, 1), have been recently established, their potential in electronic applications remains largely unexplored. Herein, we focus on the functional characterization of 1, which exhibits a reversible phase transition at Ttr = 306 K, dynamic dielectric response, and semiconducting behav...

来源：X-MOLLanthanides (Ln) offer rich and otherwise unusual chemistry, which includes their redox behavior, ligand coordination, diverse quantum phenomena, etc. Unlike the lighter elements, these f-block elements could exhibit nonlinear trends in various chemical and physical properties across the series with a noticeable break often being observed in the central atom gadolinium (Gd). This popular notion of “Gd break” has been challenged and banished by researchers in the past, making this as an ever-debated issue in the chemical fraternity. In this Letter, we examine the solvation behavior of d...
