- Insufficient sample mass limited the range of analyses performed on some samples. Analyses include: particle size distribution (PSD); X-ray fluorescence (XRF); X-ray diffraction (XRD); scanning electron microscopy (SEM); transmission electron microscopy (TEM); BET-N2 specific surface area (SSA); electron paramagnetic resonance (EPR); available surface iron (Fe); and particle-induced hemolysis (Hem)
