Low loss core-shell iron-silica nanocomposites with improved magneto-dielectric properties at radio frequencies (1 MHz-1 GHz) were successfully fabricated. A new simple method was developed to synthesize metallic iron (Fe) nanoparticles with uniform size distribution in an aqueous environment at room temperature. Citric acid and oleic acid served as surface-capping agents to control the particl...

This paper puts forth homogenization solutions for the macroscopic elastic dielectric response—under finite deformations and finite electric fields—of ideal elastic dielectric composites with two-phase isotropic particulate microstructures. Specifically, solutions are presented for three classes of microstructures: (i) an isotropic iterative microstructure wherein the particles are infinitely p...

Dynamically crosslinked materials generally lose their self-healing ability and mechanical robustness in aqueous, acidic, basic environments due to disruption of dynamic interactions bonds. Herein, a micelle-like structure with hydrophobic outer layer is used protect ionic interactions. This ensures the long-term stability ionically elastomers environments. The elastomer possesses tensile stren...
