HE PARENT magnetite NPs@ poly (amido amine) dendrimer …….(PAMAM) composite was synthesized through one pot reaction pathway.Different hybrid nanocomposites of magnetite (M NPs) of different concentrations (1*10 -3 and 3*10 -3 M) conjugated in situ with dendrimer (PAMAM)@ rice straw ash (RSA) filler were also synthesized.The finished as-synthesized nanocomposites were characterized adopting the XRD...
