The Optimization of Dispersion and Application Techniques for Nanocarbon-Doped Mixed Matrix Gas Separation Membranes
Autor: Ruben Hammerstein, Tim Schubert, Gerd Braun, Tobias Wolf, Stéphan Barbe, Antje Quade, Rüdiger Foest, Dionysios S. Karousos, Evangelos P. Favvas
Publikováno v: Membranes, Vol 12, Iss 1, p 87 (2022)
In this work, supported cellulose acetate (CA) mixed matrix membranes (MMMs) were prepared and studied concerning their gas separation behaviors. The dispersion of carbon nanotube fillers were studied as a factor of polymer and filler concentrations

Autor: Matthias Lindner, Andrei V. Pipa, Norbert Karpen, Rüdiger Hink, Dominik Berndt, Rüdiger Foest, Elmar Bonaccurso, Robert Weichwald, Alois Friedberger, Ralf Caspari, Ronny Brandenburg, Rupert Schreiner
Publikováno v: Applied Sciences, Vol 11, Iss 23, p 11106 (2021)
Avoiding ice accumulation on aerodynamic components is of enormous importance to flight safety. Novel approaches utilizing surface dielectric barrier discharges (SDBDs) are expected to be more efficient and effective than conventional solutions for p

On different modes of a filamentary atmospheric pressure plasma jet: modeling, laser schlieren deflectometric and high-speed camera investigations
Autor: Thorben Wolff, Rüdiger Foest, Holger Kersten
Publikováno v: The European Physical Journal D. 77
We investigated a filamentary non-thermal atmospheric pressure plasma jet used for coating applications. The plasma jet exhibits two different modes, the stationary mode and the locked mode, in which the filaments rotate around the plasma jet axis. W

Self-Consistent Cathode–Plasma Coupling and Role of the Fluid Flow Approach in Torch Modeling
Autor: Thorben Kewitz, Margarita Baeva, Holger Testrich, Rüdiger Foest, Tao Zhu
Publikováno v: Journal of Thermal Spray Technology. 30:1737-1750
A two-dimensional and stationary magnetohydrodynamic model of a plasma spray torch operated with argon is developed to predict the plasma properties in a steady operating mode. The model couples a submodel of a refractory cathode and its non-equilibr

Re-engineering of optical constants and layer thicknesses from in situ broadband monitoring: an oscillator model approach
Autor: Olaf Stenzel, Steffen Wilbrandt, Jens Harhausen, Rüdiger Foest
Publikováno v: Optics Continuum. 1:866
We present and discuss an in situ optical characterization methodology for calculating individual film thicknesses and optical constants of a multilayer coating. The method is applied to the plasma-ion assisted evaporation of a titania-silica five-la

Investigations on LIDT of PIAD multilayer coatings prepared by conventional and plasma diagnostics based process control
Autor: Peter Awakowicz, Rüdiger Foest, Jens Harhausen, Ralf Peter Brinkmann, Sina Malobabic, Lars Mechold
Publikováno v: Laser-induced Damage in Optical Materials 2020.
Plasma ion assisted deposition (PIAD) is a common method for the production of high-end optical interference coatings (OIC). Conventional process control is based on operating parameters like gas fluxes, voltages or currents, while the actual state o
