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 ...

Ultrahigh Strength and Exceptional Work Hardening in a Hierarchical‐Structured Alloy via Hetero‐Interface‐Mediated Twinning

open access: yesAdvanced Science, EarlyView.
This study presents a novel strategy for achieving exceptional work hardening in ultrahigh‐strength alloys by designing hierarchically heterogeneous dual‐phase (HHDP) structures, where hetero‐deformation‐induced strain gradients activate deformation twinning.

Sustainable MXene/Conductive Cellulose Heteroinks for 3D Printed High Areal Energy Density Micro‐Supercapacitors and Self‐Powered Integrated Systems

open access: yesAdvanced Science, EarlyView.
A thixotropic MXene/conductive cellulose ink is developed for 3D printed micro‐supercapacitors (MSCs) that deliver ultrahigh areal capacitance, superior energy density, and exceptional flexibility. The hydrogen‐bonded 3D network effectively suppresses MXene restacking, while graphene‐like sp2carbon pathways accelerate electron transport, boosting ...
