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...
Pyrolysis of methane is a promising, new, greenhouse gas-free production
method of hydrogen. Here, we present optical emission spectra of a microwave
plasma torch operated in an argon methane mixture. Detailed spatial
resolution is achieved by...
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...
High power impulse magnetron sputtering (HiPIMS) plasmas produce a very
energetic growth flux for the synthesis of thin films with superior
properties. High power densities in the range of a few kW/cm^2 are applied to
a metal target electrode in...
