Ion-induced secondary electron emission at a target surface is an essential
mechanism for laboratory plasmas, i.e. magnetron sputtering discharges.
Electron emission, however, is strongly affected by the target condition
itself such as oxidation...
The in-plasma-catalytic synthesis of ammonia from nitrogen and hydrogen
admixed to a helium RF plasma is studied with infrared absorption
spectroscopy, optical emission spectroscopy, and through chemical kinetics
modeling. Sandblasted glass is...
Surface dielectric barrier discharges (sDBD) are efficient and scalable
plasma sources for plasma-based gas conversion. One prominent feature of an
sDBD in this application is its ionic wind, which exerts a force on the
neutrals, thus leading to...
NO synthesis using plasma catalysis is analyzed in a parallel-plate
atmospheric pressure RF plasma from N$_2$/O$_2$ admixed to helium exposed to
Fe and Pt catalysts on a SiO$_2$ support. The NO$_x$ species are measured by
Fourier-transform...
Dielectric barrier discharges (DBD) are often used for gas conversion, such
as carbon dioxide splitting, volatile organic compound removal or ozone
generation. Due to the tiny plasma filaments in DBD discharges, efficient
mixing of the gas flow...
The plasma catalytic oxidation of n-butane diluted in a helium-oxygen RF
plasma jet is used to study volatile organic compound (VOC) removal to
unravel plasma catalytic synergisms. The plasma conversion is tested for a
stoichiometric n-butane...
Nanosecond plasmas in liquids are being used for water treatment,
electrolysis or biomedical applications. The exact nature of these very
dynamic plasmas and most important their ignition physics are strongly
debated. The ignition itself may be...
Nanosecond plasmas in liquids play an important role in the field of
decontamination, electrolysis or plasma medicine. The understanding of these
very dynamic plasmas requires information about the temporal variation of
species densities and...
Nanosecond plasmas in liquids can initiate chemical processes that are
exploited in the elds of water treatment, electrolysis or biomedical
applications. The
understanding of these chemical processes relies on unraveling the dynamics
of the...
