TL;DR: In this paper, the morphology, microstructure and surface composition of diesel engine exhaust particles were investigated by means of high resolution transmission electron microscopy, and it was found that soot agglomerates from biodiesels are more compact and spherical, as their fractal dimensions are higher.

TL;DR: An overview of the sonication technique as used in aerosol research is provided, the capacity for radical generation under these conditions is described and an analysis is given of the impact of sonication-derived free radicals on three molecular probes commonly used by researchers in this field to detect Reactive Oxygen Species in PM.

TL;DR: In this article, the potential toxicological impact of particles produced during biomass combustion by an automatic pellet boiler and a traditional logwood stove under various combustion conditions using a novel profluorescent nitroxide probe, BPEAnit.

TL;DR: The particle number size distributions showed strong dependency on feedstock and blend percentage with some fuel types showing increased particle number emissions, while others showed particle number reductions, and the median particle diameter decreased as the blend percentage was increased.

TL;DR: Several cell-free assays are currently used to quantify and detect the Reactive Oxygen Species (ROS). All of them have certain limitations, do not provide direct comparison of results and, to date, none of these assays have been acknowledged as the most suitable acellular assay and none has yet been adopted for investigation of potential PM toxicity as discussed by the authors.
