            "abstractNote": "Uniform Fe3O4 nanoparticles with diameters of 3–5 nm are successfully decorated onto the external walls of multiwall carbon nanotubes (MWCNTs) by in situ high-temperature decomposition of Fe(acac)3 in polyol solution under the irradiation of microwave. With this method, reaction time of forming Fe3O4-MWCNTs nanocomposites has been significantly shortened to 15 min. The resulting Fe3O4-MWCNTs nanocomposites show superparamagnetic property at room temperature and can be remained as stable aqueous dispersion for 2 months. Longitudinal relaxivity (r1) and transverse relaxivity (r2) of the magnetic MWCNTs are 8.34 Fe mM−1 S−1 and 146 Fe mM−1 S−1 respectively. The much higher r2 value and the obvious change in the gray scale of MR images confer the Fe3O4-MWCNTs nanocomposites as potential candidates for T2-weighted MRI contrast agents.",
