Inside Back Cover: A Library of Rare Earth Oxide Ultrathin Nanowires with Polymer‐Like Behaviors (Angew. Chem. Int. Ed. 45/2022)

The formation of ultrathin nanowires has thermodynamic advantages at low temperature. However, at low temperatures the monomers for nanocrystal growth are difficult to generate through precursor decomposition. In their Research Article (e202212251), Di Qiu, Yaping Du, and co‐workers report an efficient growth process based on adding polyoxometalate clusters to the monomers. Fifteen types of rare earth oxide ultrathin nanowires were synthesized, all exhibiting polymer‐like behavior due to the extremely high aspect ratio.
