Enhanced Electromagnetic Wave Absorption in Mapbi3 Hybrid Perovskite Through a Defect‐Tunable Green Synthesis

open access: yesSmall Structures, EarlyView.
Mechanosynthesis allowed synthesizing and providing large amount of high‐quality MAPbI3 powders with defects tuned by grinding time. Mechanosynthesized MAPbI3 for 4 h dispersed in a polymeric matrix led to a marked enhancement in dielectric loss at 11.4 GHz, which makes this green synthesis approach promising for producing hybrid perovskites with ...

Synthesis and Characterization of Novel V‐Type Hexaferrite BaFe9−xSnxO15

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
GA: The crystal structure of a new quaternary V‐type hexaferrite with the composition BaFe9−xSnxO15, found in the system Ba–Fe–Sn–O, is reported. A novel V‐type hexaferrite with the composition BaFe9−xSnxO15 with 1.57 ≤ x ≤ 1.84 (from wavelength dispersive X‐ray spectroscopy [WDX] data) is synthesized by reacting BaCO3, Fe2O3, SnO2, and Na2CO3 as flux ...

Deep learning model for enhanced power loss prediction in the frequency domain for magnetic materials

open access: yesIET Power Electronics, EarlyView.
This paper outlines the methodology for predicting power loss in magnetic materials. A neural network based method is introduced, which adopts a long short‐term memory network, expressing the core loss as a function of magnetic flux density in the frequency domain, temperature, frequency, and classification of the waveforms.
