Laser-induced incandescence : recent trends and current questions

TL;DR: An overview of fundamental experimental and theoretical aspects of soot measurements by laser-induced incandescence (LII) is provided in this paper. But despite the widespread application of LII for soot-concentration and particle-size measurements, there is still a significant lack in fundamental understanding for many of the underlying physical processes.
Journal ArticleDOI

Resonance-stabilized hydrocarbon-radical chain reactions may explain soot inception and growth

TL;DR: Experimental and theoretical evidence is presented for rapid molecular clustering–reaction pathways involving radicals with extended conjugation involving PAHs and other hydrocarbon species to form covalently bound complexes that promote further growth and clustering by regenerating resonance-stabilized radicals through low-barrier hydrogen-abstraction and hydrogen-ejection reactions.
Journal ArticleDOI

Electrokinetic resolution of amino acid enantiomers with copper(II)-aspartame support electrolyte

TL;DR: Analyse de melanges racemiques de 14 aminoacides dansyles, pour des concentrations inferieures a la fentomole as mentioned in this paper, for des proportions inferieure a la Fentomelle.

Laser-induced incandescence: Particulate diagnostics for combustion, atmospheric, and industrial applications

TL;DR: A review of laser-induced incandescence (LII) for combustion diagnostics can be found in this paper, where the authors consider two variants of LII, one that is based on pulsed-laser excitation and has been mainly used in combustion diagnostic and emissions measurements, and an alternate approach that relies on continuous-wave lasers and has become increasingly popular for measuring black carbon in environmental applications.

Stratospheric water vapor increases over the past half‐century

TL;DR: In this paper, the authors analyzed ten data sets covering the period 1954-2000 to show a 1% per year increase in stratospheric water vapor, which is unlikely the result of a single event but rather indicative of long-term climate change.
