Biphasic Ni‐MXene Quantum‐Confined Nanostructures: A Versatile Janus Platform for Advanced Energy Storage and Catalytic Oxidations

open access: yesAdvanced Materials, EarlyView.
A biphasic Ni‐MXene quantum‐confined nanostructure (Ni‐MJQD) serves as a Janus platform, simultaneously achieving high‐performance energy storage and efficient catalytic oxidation. The unique architecture enables superior energy storage performance and selective benzyl alcohol oxidation‐symbolizing “one stone, two birds” for sustainable energy and ...

Sub‐1000 °C Sintering of Protonic Ceramic Electrochemical Cells via Microwave‐Driven Vapor Phase Diffusion

open access: yesAdvanced Materials, EarlyView.
A transformative microwave‐driven vapor‐phase sintering strategy enables densification of proton‐conducting electrolytes at 980 °C, reducing the sintering temperature by over 500 °C and addressing a major bottleneck toward PCEC manufacturing. Abstract Protonic ceramic electrochemical cells (PCECs) hold significant promise for efficient power generation

Supramolecular Interface Engineering via Interdiffusion for Reusable and Dismantlable Polymer Adhesion

open access: yesAdvanced Materials, EarlyView.
Reversible adhesion via host–guest complex formation at the polymer interface is achieved by externally controlling the complexation through applied stimuli. Neutron reflectometry analysis of the adhesion interface revealed that the presence of host–guest complexes hinders the polymer interdiffusion by despite promoting adhesion strength.

Anti‐Corrosive Covalent Iodo‐Thiadiazole Catalyst Enables Aqueous Zn─S Batteries with High Coulombic Efficiency

open access: yesAdvanced Materials, EarlyView.
In aqueous Zn–S batteries, a covalently bonded iodo–thiadiazole redox mediator suppresses parasitic I3−‐mediated Zn corrosion and enhances Zn–S redox kinetics, enabling pouch cell with a high capacity of 1398 mAh g−1 after 120 cycles. This innovative catalyst design is a leap toward practical and grid‐scale aqueous Zn–S batteries. Abstract Aqueous zinc‐

Copper Catalysts Inherit and Retain Precatalyst Morphology in Extended CO Electroreduction to n‐Propanol

open access: yesAdvanced Materials, EarlyView.
Flash Joule heating enables the formation of quenched Cu oxide precatalysts with intragrain‐in‐grain architectures. These hierarchical structures are inherited after electroreduction, suppressing reconstruction even at high current densities in an MEA cell.
