Inactivation of Escherichia coli by atmospheric pressure plasma jet in water
Journal of Water and Health, 2022 The main aim of this work is inactivation of Escherichia coli in water using a laboratory-scale radio-frequency atmospheric pressure Argon plasma jet. This bacterium is widely present in the environment, especially in drinking water, and its pathogenic ...

Spectroscopy of laboratory plasmas [PDF]
Space Science Reviews, 1972 AbstractWork under the heading of Laboratory Plasma Spectroscopy may be conveniently separated into three classes depending on the extent to which the interaction of the emitting atoms with their plasma environment is central to the investigation. Zero order, the longest established use of laboratory plasmas in connection with astrophysics, concerns ...

Temporally resolved laser induced plasma diagnostics of single crystal silicon - effects of ambient pressure [PDF]
, 2008 Laser-Induced Breakdown Spectroscopy of silicon was performed using a nanosecond pulsed frequency doubled Nd:YAG (532 nm) laser. The temporal evolution of the laser ablation plumes in air at atmospheric pressure and at an ambient pressure of ∼10−5 mbar

Experimental Realization of an Exact Solution to the Vlasov Equations for an Expanding Plasma [PDF]
, 2007 We study the expansion of ultracold neutral plasmas in the regime in which inelastic collisions are negligible. The plasma expands due to the thermal pressure of the electrons, and for an initial spherically symmetric Gaussian density profle, the ...
