Synergistic Integration of SrFeO<sub>3</sub> Nanoparticles With Exfoliated MXene (Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub>/V<sub>2</sub>CT<sub>x</sub>) Nanosheets for High Performance Supercapacitors. [PDF]
SmallA facile mechanical mixing, probe‐sonication, and annealing strategy was employed to intercalate SrFeO3 nanoparticles between Ti3C2Tx and V2CTx MXene sheets, constructing robust heterostructures for advanced supercapacitors. The inserted perovskite suppresses MXene restacking while contributing additional Faradaic redox activity.

Anomalous Enhancement in MXene-Based Electrochemical Actuators: Pseudo-Capacitance-Induced Multi-Charge Accumulation in Confined Space. [PDF]
Adv Sci (Weinh)We elucidate the electrochemical actuation mechanism of 2D material‐based electrodes within a MXene‐centered framework, linking atomic‐scale surface chemistry to macroscopic performance (see schematic). Mechanistically, the reduction of Ti─O─Ti sites in H2SO4 triggers the accumulation of hydrated ions at confined active sites, resulting in anomalous ...
