Controlling Bubble and Skyrmion Lattice Order and Dynamics via Stripe Domain Engineering in Ferrimagnetic Fe/Gd Multilayers

Advanced Physics Research, EarlyView.
The density and ordering of the bubble/skyrmion lattice hosted by Fe/Gd multilayers can be significantly enhanced using an in‐plane field to align the stripe domain state. As a result, the laser‐induced breathing mode dynamics are strongly modified, showing both an increased amplitude and frequency.

New Insights in the Electrochemical Stability of Various Solid Polymer Electrolytes/Layered Positive Metal‐Oxide Electrode Interfaces in Solid‐State Lithium‐Ion Battery

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this work, the electrochemical compatibility of a broad range of solid polymer electrolytes with two Ni‐rich nickel–manganese–cobalt cathodes (NMC622, NMC811) is investigated through a hybrid computational and experimental approach. The relative reactivity of NMC811 to NMC622 is demonstrated, as well as the role of Li cations in the electrolyte ...

High‐Fidelity Simulation‐Driven Control Framework for Robust Grid Integration of Renewable Energy Systems

Energy Science &Engineering, EarlyView.
This work proposes a high‐fidelity, simulation‐driven control framework for robust grid integration of hybrid PV–wind systems using a modular, hierarchical multi‐loop architecture with adaptive decision logic. The framework coordinates power, DC‐link voltage, and grid currents under fast load and generation changes, enabling safe exploration of extreme
