Deformation Behaviors in Single BCC‐Phase Refractory Multi‐Principal Element Alloys under Dynamic Conditions

open access: yesAdvanced Science, EarlyView.
Exceptional mechanical stability of refractory multi‐principal element alloy (RMPEA) across various strain‐rates and temperature is studied through multiscale experiments coupled with theoretical calculations. This stability originates from competition between twinning and adiabatic heating during dynamic deformation, contributed from severe lattice ...

Multifunctional and Flexible Phase Change Composites for Dual‐Mode Thermal Management of Lithium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
This study develops flexible, leakage‐proof phase change composites with dual‐mode thermal management for lithium‐ion batteries. The composites offer Joule heating, passive cooling, and temperature sensing. Simulations validate their performance and provide insights into material optimisation.

Direct Visualization of Surface Structure and Charge States of Ceria‐Supported Gold Catalysts Under Redox Conditions

open access: yesAdvanced Science, EarlyView.
In the characterization of supported metal catalysts, a crucial aim is to conduct nanoscale analysis of the surface structure and charge dynamics in reactive gases. This study uses high‐precision electron holography in gas environments to observe the charge states of Au nanoparticles (NPs) supported on CeO2 during redox cycles.

Shape Memory Graphene with Ultrahigh Specific Energy Dissipation

open access: yesAdvanced Science, EarlyView.
Molecular dynamics simulations are used to show that van der Waals interaction is critical for the mechanical properties of nano‐architected triangular graphene. Interplay between the flexibility and high Young's modulus of graphene, the designed architecture, and the van der Waal interaction between graphene ligaments results in a shape memory effect ...
