TL;DR: In this article, a Half Mini DMA was applied to study the kinetics of sub-2-nm TiO2 nanoparticle formation in a furnace aerosol reactor, through the thermal decomposition of titanium tetraisopropoxide (TTIP), and a first order reaction rate derived from the dependence of size distributions on reaction temperature matched well with existing literature data.

TL;DR: In this article, a detailed comparison of the chemical compositions between organic aerosol emissions from coal combustion and organic tars from coal pyrolysis, which is an early stage of coal combustion, was presented.

TL;DR: In this article, the charging characteristics of flame-generated sub-3-nm particles were investigated with three enhanced particle detectors including a high resolution differential mobility analyzer (DMA) coupled with an electrometer, a particle size magnifier coupled with a butanol-based condensation particle counter (PSM-bCPC), and an atmospheric pressure interface time-of-flight mass spectrometer (APi-TOF).

TL;DR: In this paper, a Half Mini DMA (TSI model 3085) was compared with a Nano DMA for sub 2-nm size distribution measurements of organic ions generated by electrospray of tetra-heptyl ammonium bromide (THAB) solution and aerosols generated by a premixed flat flame reactor.

TL;DR: The detection of monomers, dimers, trimers, and tetramers was detected for the first time in a flame aerosol reactor during the synthesis of pristine TiO2 andTiO2/SiO2 nanocomposites and supported previous hypotheses that collisional growth from stable monomers of metal oxides is the first step of particle growth.
