Gas-liquid mass transfer intensification for bubble generation and breakup in micronozzles
Autor: Lena Mensing, Felix Reichmann, Jakob Herath, Norbert Kockmann
The local gas-liquid mass transfer was characterized during bubble generation in T-contactors and in an adjacent micronozzle. A colorimetric technique with the oxygen sensitive dye resazurin was investigated to visualize gas-liquid mass transfer duri

New insights into the electronic states of the Ge(0 0 1) surface by joint angle-resolved photoelectron spectroscopy and first-principle calculation investigation
Autor: Mattia Mulazzi, Leo Miglio, Felix Reichmann, Emilio Scalise, Francesco Montalenti, Giovanni Capellini, Andreas Becker, Wolfgang M. Klesse, Emily V.S. Hofmann, J. Dabrowski
Publikováno v: Applied Surface Science. 571:151264
While the Ge(0 0 1) surface has been extensively studied, it is still debated whether it is of conducting or semiconducting nature at room temperature. The evidence collected by angle-resolved photoelectron spectroscopy experiments in the past has le

Gas-liquid dispersion in micronozzles and microreactor design for high interfacial area
Autor: Norbert Kockmann, Alexander Tollkötter, Felix Reichmann, Sarah Körner
Publikováno v: Chemical Engineering Science. 169:151-163
Gas-liquid flow is frequently investigated in microreactor research, but mainly focused on well-described Taylor-bubble flow. Dispersed flow featuring small bubbles results in increased specific surface-to-volume ratio and more stable flow in microch

Non-Invasive Temperature Measurement for Polyimid-Based Microstructured Devices
Autor: Jakob Zimmermann, Jens Bobers, Norbert Kockmann, Felix Reichmann
Publikováno v: ASME 2019 17th International Conference on Nanochannels, Microchannels, and Minichannels.
Besides the common benefits of micro-structured reactors such as enhanced mass and heat transfer caused by a high specific surface and enhanced mixing, they have also drawbacks due to their tiny dimensions. Non-invasive temperature measurement is an
