Effects of oxygenated biofuel additives on soot formation: A comprehensive review of laboratory-scale studies
TL;DR: In this article , a review of recent laboratory studies on sooting characteristics of neat or blended oxygenated fuels is presented, with a focus on the chemical cross-linking effects (or soot synergistic effect s) occurring in the oxygenated/hydrocarbon fuel mixtures.

Effects of oxygenated biofuel additives on soot formation: A comprehensive review of laboratory-scale studies
TL;DR: In this paper, the effects of various oxygenated fuels (e.g., alcohols, ethers, esters, or real biodiesel) on soot formation in combustion of conventional hydrocarbons are discussed in detail.
Journal ArticleDOI
Study on fluorescence spectroscopy of PAHs with different molecular structures using laser-induced fluorescence (LIF) measurement and TD-DFT calculation.
TL;DR: The experimental results showed that the fluorescence emission wavelengths increased with more aromatic (benzenoid) rings, but this relationship no longer existed when the PAH molecules contain the five-membered ring structures, and the TD-DFT results indicated that the aliphatic branched chains changed the electric structures of HOMO and LUMO of the core aromatic rings, and then influence the fluorescent emission wavelength ranges.

Counterflow diffusion flames
TL;DR: Laminar counterflow diffusion flames are generally referred to as the pure diffusion flame as discussed by the authors, and they can be classified into four types: (i) counterflow between two opposed jets, (ii) flat, counter-flow diffusion flame between two matrix burners, (iii) counter flow diffusion flame in the forward stagnation region of a spherical or hemispherical porous burner, and (iv) the counterflow diffuser flame in a cylindrical porous burner.
