<p>The evaluation of the ion diffusion mechanism and magnetic properties of ecofriendly strontium-copper ferrite-based nanomaterials for hydroelectric cells via the green synthesis technique using plant-extract-facilitation is an innovative nanotechnology approach for the ecologically sustainable and economical manufacturing of nanoparticles. The coprecipitation synthesis of strontium and copper ferrite nanomaterials was successfully carried out using green plant extracts i.e., aloe vera, ensuring environmental sustainability. x-ray diffraction analysis verified the establishment of the pure crystalline phase, and the nanometer-scale structural parameters and crystallite size were determined. Field emission scanning electron microscope (FESEM) images confirm more or less spherical particles for CuFe₂O₄, with a size of 79&#xa0;nm, whereas that of 7.5% Sr:CuFe₂O₄ is 99&#xa0;nm. Fourier transform infrared (FTIR) spectroscopy revealed a monophase spinel crystal structure. The dielectric behavior exhibited an exponential decline in both the constant and loss factor as frequency increased, whereas the ion diffusion mechanism confirms better-quality dielectric, impedance properties of nanomaterials. The saturation value was determined through magnetic measurements using a vibrating sample magnetometer (VSM) instrument at ambient temperature. The CuFe₂O₄ nanomaterial exhibited a greater performance with a current of 3.7&#xa0;mA and 7.5%Sr:CuFe₂O₄ nanomaterial showed an extreme of 1.4&#xa0;mA, highlighting the pathways for ion diffusion. These results establish strontium and copper-ferrite nanomaterials as advantageous for microelectronic and hydropower applications.</p> Graphical Abstract <p></p>
