The non-luminous surroundings of atmospheric pressure plasma jets contain still substantial electron density which can be of practical importance, when e.g. reactant or precursor is introduced into this zone. Low signal-to-noise ratio makes the Stark

Few-layer graphene nanosheets were synthesised from ethanol using a microwave plasma torch. The stability of the discharge permitted us to directly observe and analyse two distinctive structures—a plasma zone and an assembly zone. Important plasma

Fourier-transform infrared spectroscopy and proton-transfer-reaction–mass spectrometry are used in a complementary way to study gas-phase processes during decomposition of ethanol in a microwave plasma torch. Decomposition products (C, C2 and simpl
