Structural Transitions and Melting of Two-Dimensional Ion Crystals in RF Traps
EntropyWe investigate the structural properties and melting behaviors of two-dimensional ion crystals in an RF trap, focusing on the effects of ion temperature and trap potential symmetry. We identify distinct crystal structures that form under varying trapping

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites
Advanced Functional Materials, EarlyView.We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...

[2]Catenanes Displaying Switchable Gin-Trap-Like Motion
, 2018 Sodium ion-controlled switching from “folded” to “linear” states results in significant changes in the molecular shape of a [2]catenane, such that it mimics the operation of a gin trap, with a fluorescent alarm signal appearing when pyrene side arms ...
