Harnessing tailored nanoscale magnetic materials like metal-organic frameworks for advanced applications has faced two key challenges – reliably constructing these frameworks with specific and programmable architectural arrangements and effectively characterizing these nanostructures. Researchers in China strategically dispersed magnetic Co nanoparticles into a meticulously layered nanoporous framework with the bottom and upper nanopores exhibiting a staggered arrangement. The staggered nanoporous structure intricately shapes the magnetic flux lines into a Chinese knot shape, significantly altering its magnetic characteristics. Such a transformation remarkably enhances the material’s efficacy in absorbing electromagnetic waves, covering the Ku band even at a minimal thickness of 1.7 mm. According to the researchers their work provides a roadmap for developing more efficient electromagnetic wave absorbers and open new possibilities in manipulating magnetic properties for various advanced technological applications… read more.
