Data publication: Measurement of liquid foam flow through a diverging nozzle

Skrypnik, Artem; Lappan, Tobias; Knüpfer, Leon; Ziauddin, Muhammad; Arnal Tribaldos, Icíar; Shevchenko, Natalia; Heitkam, Sascha;

The hydrodynamic theory of pneumatic foam analytically predicts the advective transport of liquid by foam rising continuously in a vertical column or pipe, relying on cross-sectional averaging of the foam velocity and liquid fraction. This experimental study accumulates a database for assessing the

Data publication: Generating structured foam via flowing through a wire array

Skrypnik, Artem; Knüpfer, Leon; Trtik, Pavel; Lappan, Tobias; Ziauddin, Muhammad; Heitkam, Sascha;

The structure of liquid foam is generally considered random and isotropic. However, when foam flows past a set of wires, an inhomogeneous liquid fraction distribution, or layering, can be observed within the bulk. This dataset presents neutron radiography data of foam flowing past a set of thin meta

Data publication: Dual wetting electrode surfaces for alkaline water electrolysis

Rox, Hannes; Ränke, Fabian; Zschach, Lis Geraldine; Yang, Xuegeng; Mutschke, Gerd; Eckert, Kerstin; Lasagni, Andrés Fabián; Baumann, Robert;

Tuning the electrode surfaces for better bubble management is a promising approach to increase the efficiency of alkaline water electrolysis. Therefore, Direct Laser Writing was used to structure Nickel electrodes with a dual wetting surface. The applied pillar-like structure combines superhydrophil
