Ultra High Step‐Up Soft Switching Converter Based on the Interleaved Structure

Energy Science &Engineering, EarlyView.
The proposed topology provides high voltage gain and enhanced efficiency at low duty cycles, thereby reducing conduction losses in the switches. Its interleaved structure ensures current sharing, while the switches experience both low voltage and low current stress, further decreasing conduction losses.

Bulk‐Edge Correspondence and Multiplexing Topological Routings in Gyromagnetic Photonic Weyl Metamaterials

Laser &Photonics Reviews, EarlyView.
In this work, various topological phases and the bulk‐edge correspondence are studied and established in gyromagnetic photonic Weyl metamaterials. Based on rigorous theoretical analysis, the comprehensive depictions of the multiple topological phase diagrams and multi‐type bulk‐edge correspondences are further mapped out.

Effect of Nanoparticles Type and Content on the Antimicrobial Activity of Magnetoelectric Polymer‐Based Composites

Macromolecular Bioscience, EarlyView.
Magnetoelectric P(VDF‐TrFE) nanocomposites containing CFO or Fe3O4 nanoparticles were developed to generate electroactive microenvironments under magnetic stimulation. At 1 Hz, particularly with 20% CFO, strong antimicrobial effects were observed against E. coli and S. aureus. This approach highlights the potential of magnetically activated surfaces to
