Interface Rectification via Roll‐to‐Roll Dual‐Confinement Nanocoatings for High‐Temperature Polymer Capacitors

open access: yesAdvanced Science, EarlyView.
Dual confinement in self‐assembled nanocoatings regulates polymer dynamics and hot‐carrier transport, enabling an interface‐rectification strategy for high‐temperature polymer capacitive energy storage. ABSTRACT Polymer film capacitors are indispensable for energy storage and power conversion, yet their energy density and efficiency deteriorate rapidly

Accelerated Discovery of Earth‐Abundant Oxygen Evolution Catalysts Through Surface‐Informed Active Learning

open access: yesAdvanced Science, EarlyView.
A surface‐informed active learning framework integrated with density functional theory enables resource efficient screening of the NiCoFe ternary composition space. Experimental validation identifies Ni55Co10Fe35 as the optimal composition, exhibiting favorable oxygen evolution reaction kinetics.

Potassium‐Impurity‐Modulated Self‐Trapped Excitons and Energy Transfer in Phase‐Separated, Mn4+‐Doped Li2HfF6

open access: yesAdvanced Science, EarlyView.
Li2HfF6 contains two spectroscopically distinct self‐trapped excitons (STEs): intrinsic STE1 and redshifted, K‐associated STE2. Potassium incorporation stabilizes STE2, which selectively sensitizes Mn4+ red emission. This work uncovers the often‐overlooked role of trace K impurities, demonstrating impurity modulation as an effective strategy for tuning

Proximity Sounding Analysis of Supercell Environments in Finland

open access: yes
Supercells are thunderstorms characterized by a persistently rotating updraft, which is separated from, and in quasi-steady state with the downdraft. The structure of a supercell allows for long-lived thunderstorms, capable of producing severe weather ...

Magnetoelectric Multiferroics for the Next‐Generation Ultralow‐Power Electronics

open access: yesAdvanced Science, EarlyView.
Magnetoelectric coupling provides a unifying route from electric‐field control of magnetic order to non‐volatile MeRAM, MESO logic, and emerging antiferromagnetic and magnonic devices. By connecting switching physics with device benchmarks, material platforms, and integration strategies, distinctive technological opportunities are identified alongside ...
