TL;DR: Iron speciation by Mössbauer spectroscopy indicates that ferric iron in an aluminosilicate glass phase is the source of the bioavailable iron in coal fly ash and that this iron species is associated with combustion particles, but not with crustal dust derived from soil minerals.

TL;DR: In this paper, the effects of temperature, O 2, and OH on the evolution of soot size distributions during oxidation were evaluated experimentally in a two-stage burner, where soot was produced in a first-stage premixed burner, while in a second stage, the soots was oxidized under fuel-lean and slightly-rich conditions.

TL;DR: Ultrafine mass concentrations were directly related to estimated particle temperature, increasing with increasing temperature, and for high silicon and calcium coals, Utah Skyline and PRB, there was a secondary effect due to CO(2) and the hypothesized reaction.

TL;DR: Particulate-phase exhaust properties from two different types of ground-based jet aircraft engines—high-thrust and turboshaft—were studied with real-time instruments on a portable pallet and additional time-integrated sampling devices and successfully characterized rapidly changing particulate mass, light absorption, and polycyclic aromatic hydrocarbon (PAH) content.

TL;DR: In this article, a two-stage burner was used to characterize the oxidation of soot from different n -butanol blends, 10, 30, and 60 mmol% in n -dodecane.
