ABSTRACT: Diesel particulate with different aerodynamic sizes was collected from a medium-duty diesel engine using a microorifice uniform deposition impactor (MOUDI). High-resolution transmission electron microscopy (HRTEM) and thermogravimetric analysis (TGA) were used to investigate the volatility, morphology, inner nanostructure, and oxidation behavior of the particulate in four aerodynamic size bins of
