To enable the investigation of the flame chemistry of precursor-laden nanoparticle forming spray flames in quasi-one-dimensional geometry, a matrix burner was developed in which a laminar flat flame is uniformly supplied with liquid aerosol. In the p

Spray flame synthesis is an important technique for the production of metal oxide nanoparticles. Micro-explosions of the burning and evaporating droplet are an important breakup mechanism that is usually necessary in order to achieve a homogeneous pr

The Shannon entropy is a rigorous measure to evaluate the complexity in dynamical systems. Shannon entropy can be directly calculated from any set of experimental or numerical data and yields the uncertainty of a given dataset. Originating from infor

Tetramethylsilane is a precursor often used for the production of flame-synthesized silica nanoparticles or coatings. This study investigates the chemical reaction mechanism of tetramethylsilane in a series of H2/O2/Ar low-pressure (p = 30 mbar) flam

The simulation of spray flame processes for the production of high-quality nanoparticles relies on thermophysical properties of the precursor solutions, for which literature data are scarce. Here, we report experimental thermophysical data of solutio
