Morphology, composition, and mixing state of primary particles from combustion sources — crop residue, wood, and solid waste

Abstract Morphology, composition, and mixing state of individual particles emitted from crop residue, wood, and solid waste combustion in a residential stove were analyzed using transmission electron microscopy (TEM). Our study showed that particles from crop residue and apple wood combustion were m...
