Dynamics of plasma gratings in atomic and molecular gases [PDF]
Physical Review E, 2012 The decay of the plasma grating formed at the intersection of two femtosecond filaments is measured in several molecular and atomic gases. The grating evolution is ruled by ambipolar diffusion in atomic gases and by a combination of ambipolar diffusion and collision-assisted free electron recombination in molecular gases.

Gene Expression Alteration by Non-thermal Plasma-Activated Media Treatment in Radioresistant Head and Neck Squamous Cell Carcinoma [PDF]
Clinical and Experimental OtorhinolaryngologyObjectives. Head and neck squamous cell carcinoma (HNSCC) exhibits high recurrence rates, particularly in cases of radioresistant HNSCC (RR-HNSCC). Non-thermal plasma (NTP) therapy effectively suppresses the progression of HNSCC. However, the therapeutic

Particle Models of Discharge Plasmas in Molecular Gases [PDF]
, 2004 We describe a mixed particle/continuum model for discharge plasmas in molecular gases developed by our group, which couples a particle description of the plasma phase with the diffusion/reaction kinetics of atoms and molecules in the gas phase. The model includes an improved treatment of ion kinetics, which fits some serious problems of multi time ...

Statistical thermodynamics of dissociating gases and plasmas [PDF]
The Journal of Chemical Physics, 1979 When a dissociation equilibrium is present, the complete phase space should be allocated consistently to either the associated or dissociated species without duplication or omission of any important region. While this problem is trivial in many systems at low pressure, it becomes important and complex for an ionizing system at high pressure. A feasible
