High‐Entropy Chemical Composition Design for Ultrahigh Capacitive Energy Storage

Advanced Science, EarlyView.
La‐donor doping suppresses defect charges and reduces domain size via local random fields. Conversely, NaNbO3 addition in BNT‐based ceramics stabilizes the orthorhombic phase. This creates R‐O‐T multiphase polar nanoregions within a cubic matrix, which lowers the energy barrier, delays polarization saturation, and enables a high breakdown strength ...

Neural Network‐Based Permittivity Engineering of Magnetic Absorbers for Customizable Microwave Absorption

Advanced Science, EarlyView.
A neural network‐enabled permittivity engineering paradigm is introduced, transcending traditional trial‐and‐error design. By decoupling electromagnetic parameters and screening a high‐throughput feature space, an ultrathin (1.0 mm) magnetic absorber is inversely designed, experimentally achieving a superior and customizable 5.1 GHz bandwidth and ...
