Spray flame synthesis (SFS) can be used to produce a variety of metal oxide nanoparticles. In order to better understand and further develop this complex process, the LTT has been using various optical methods for many years. In this article, this work is continued and the formation of iron oxide pa...

This paper describes the successful use of the exhaust gas stream from a porous burner to provide the heat for the endothermic dehydrogenation of hydrogen-rich LOHCs.
European Combustion Meeting in Rouen, France
Using a novel approach that combines broadband extinction measurements with tomographic methods, this work demonstrates the first in situ planar determination
In this work a hydrogen burner was developed, numerically optimized and experimentally characterized.
We would like to welcome Mr. Stefan Buchstaller as a new staff member.
In this publication, you will find out how temperatures in heat transfer oils or in liquid organic hydrogen carrier (LOHC) systems can be determined using the optical measurement method of phosphor thermometry.
In this paper, you will learn how the power density and the dynamics of the hydrogen release reaction can be improved via direct heating of the dehydrogenation unit using a porous media burner.
Doctoral thesis "Investigation of Soot Formation by Optical Diagnostics: From Precursor Measurements to 3D Particle Sizing"
New employee in the group Combustion and Reactive Flows introduces himself.
With this book, Prof. Stefan Will and his internationally renowned co-authors pursue a concept that complements that of conventional textbooks.
After a long Corona-related abstinence, two important conferences finally took place again in presence!
During the Long Night of Sciences on May 21, 2022, the LTT presented two current research projects.
In this publication you will learn how optical measurement methods (in-situ UV-Vis-NIR extinction and ex-situ Raman spectroscopy) are used to determine the band gaps of soot particles at two different stages during the soot formation process!
In this publication you will learn how a flexible setup for two-line atomic fluorescence (TLAF) can be used for temperature measurement in flames!
In this publication, you will learn how wide-angle light scattering (WALS) is used to determine the size distributions of microdroplets and nanoparticles of different morphologies (fractal/spherical) in a complex spray flame process!
