Supercapacitor Safety: Overcharge‐Induced Failure Mechanisms in Electrochemical Double‐Layer Capacitors

Advanced Science, EarlyView.
Time‐resolved synchrotron radiography reveals the internal evolution of electrochemical double‐layer capacitors under abusive overcharge. EDLCs are shown to follow a thermally driven failure pathway involving electrolyte decomposition, gas generation, and structural collapse, distinct from chemically driven thermal runaway effects of Lithium‐ion ...

Architected Spatially Deterministic Multiscale Phase Segregation in Block Copolymer Composites for Augmented Radiative Cooling

Advanced Science, EarlyView.
Multiscale phase segregation in block copolymers enables spatially deterministic structuring from molecular to macroscopic scales, decoupling solar scattering and infrared emission for augmented radiative cooling. ABSTRACT Passive radiative cooling, which reflects solar irradiation while emitting heat through the atmospheric window, provides a ...

Operando Identification of the Active Phase in Sr‐Promoted Lanthanum Cobaltite Perovskite‐Derived Catalysts for Ammonia Decomposition

Angewandte Chemie, EarlyView.
Ammonia decomposition catalyzed by base metals: Exsolution of cobalt from perovskites prepared by spray‐flame synthesis (SFS) yields highly active, SrO‐promoted Co/La2O3 catalysts with low cobalt content. Operando studies provide insight into the function of the promoter. Dynamic surface reconstruction under operating conditions increases the interface
