Environmental applications of low-temperature plasmas

Collision Processes in Low-Temperature Hydrogen Plasmas

Collision processes among the constituents of low-temperature hydrogen plasmas (e,H,H,H,H2,H + 2 ,H + 3 ) play a key role in technical plasma applications as well as in the boundary regions of magnetically confined fusion plasmas. In this work a review of the current knowledge on their cross sections is presented. Collision processes of electronically and vibrationally excited species are also ...

Boltzmann-Equation Simulations of Radio-Frequency-Driven, Low-Temperature Plasmas

Impact of low-temperature plasmas on Deinococcus radiodurans and biomolecules.

The effects of cold plasma on Deinococcus radiodurans, plasmid DNA, and model proteins were assessed using microbiological, spectrometric, and biochemical techniques. In low power O(2) plasma (approximately 25 W, approximately 45 mTorr, 90 min), D. radiodurans, a radiation-resistant bacterium, showed a 99.999% reduction in bioburden. In higher power O(2) plasma (100 W and 500 mTorr), the reduct...

Simulations of Low-temperature Plasmas with Adaptive Cartesian Mesh

Many problems of gas discharge physics are characterized by the presence of large gradients of plasma parameters in localized domains (streamers, filaments, ionization fronts, etc). For such problems, the ability to dynamically adapt the mesh resolution to local plasma properties can substantially increase the accuracy and efficiency of simulations. This paper describes a new tool for plasma si...
