This study reports facile in situ synthesis of magnetically retrievable nanocomposites of nanocellulose (derived from waste biomass) and NiFe2O4 nanoparticles using hydrothermal method. The synthesized nanocomposites were characterized using various techniques such as FT-IR. powder XRD. HR-TEM. https://parisnaturalfoodes.shop/product-category/blueberry-conc/
