Abstract The dielectric-magnetic matching effect emerges from the presence of dual dielectric relaxation and multiple magnetic resonances. This phenomenon becomes a strategic approach in quest to enhance microwave absorption performance by optimizing components. Herein, binary ternary ferromagnetic alloy with tunable components embedded carbon skeleton (core/shell) nanocapsules has been successfully fabricated one step metal-organic chemical vapor deposition. core/shell structure design introduces numerous interfaces that amplify loss stemming polarization. It is important emphasize modifying composition core these effectively regulates impedance characteristics. As result, CoFeNi/C demonstrate an optimal reflection (RL min ) −53.6 dB at thickness 2.55 mm, alongside effective bandwidth 5.92 GHz 2.05 filling ratio as low 20 wt%. study provided valuable insights into promising avenue for fabricating nanocomposites outstanding attenuation capabilities through manipulation composited elements.

High entropy materials exhibit unparalleled reactivity and tunable electrochemical properties, putting them at the forefront of advances in electrocatalysis for water splitting. Their various interfaces elements are purposefully engineered nanoscale, which is essential to enhancing their characteristics. The exceptional catalytic efficiency observed graphene-coated nanoparticles (NPs) with an inner high-entropy alloy (HEA) (HEA@C) a result combined action several metallic constituents. However, increasing still very difficult task, particularly when it comes obtaining precise control over composition structure via efficient synthesis techniques. HEA@C NPs adaptable characteristics allow perform better slow oxygen evolution (SOE) activities. novel multilayer graphene-enhanced HEA CoNiFeCuV@C electrocatalyst presented this work carbon-based, transmission electron microscopy (TEM) investigations verify its efficacy. reaction (OER), hydrogen (HER), reduction (ORR) greatly increased by electrocatalyst. electrocatalytic performance core-shell remarkable HER, OER, ORR, even though highly stressed lattice has structural flaws.
