Note on the shape circularity measure method based on radial moments
We show that the so-called circularity measures based on radial moments, are a particular case of the family of circularity measures introduced recently by the authors of this note

Synthesized sample were characterized with X-ray powder diffraction method (XRDP). electrone microscopy (SEM and TEM), vibrating sample magnetometry (VSM) and vibrational spectroscopy methods (FTIR and Raman). Mathematical analysis of nanoparticle morphology was also conducted, applying shape descriptors on segmented TEM sample images..
