A combination of inactivation experiments, test strip measurements,and a2D model of afterglow chemistry is employed to identify the key active species and reaction pathways leading to Escherichia coli inactivation by an atmospheric-pressure plasma jet. The jet operates either in helium or in a helium/oxygen mixture, and it is shown that the inactivation mechanisms are different in the two cases.

3-Aminopropyltriethoxysilane (APTES) nanocoatings have been deposited by an atmospheric pressure plasma jet produced generated from air and APTES mixtures. The retention of amine groups in the organosiloxane coatings is studied and compared to post-treated and -grafted APTES coatings.

The coupling of eedf with the excited state kinetics in non-equilibrium plasmas is discussed, considering (1) the role of H2(v), formed in heterogeneous recombination, in affecting the yield H− in a moderate-pressure RF plasma, (2) the role of H(n) in modelling the H2/He nozzle expansion in optically thin and thick cases and (3) the role of vibrationally and electronically excited states in the CO2 activation under discharge and post-discharge conditions.
- Calculation of Electron-Scattering Cross Sections Relevant for Hypersonic Plasma Modeling

The dynamics of electron-NO scattering for the optically allowed excitations to the B 2Π and C 2Π states is investigated within the similarity approach, reformulated in order to include non-adiabatic vibronic coupling effects in the vibrational dependence of the state-to-states cross sections.
- Effect of Substrate Temperature on Thermal Properties and Deposition Kinetics of Atmospheric Plasma Deposited Methyl(methacrylate) Films
Gill Scheltjens, Guy Van Assche and Bruno Van Mele

In this work, the effect of Tsubstrate on the plasma deposition kinetics and thermal properties of pdMMA films is assessed. A plasma deposition mechanism is proposed, based on the adsorption/desorption equilibrium of activated species, followed by a surface plasma polymerization. A decreased volatile fraction and enhanced cross-link density with increasing Tsubstrate is shown by TG analysis. In accordance, DSC analysis confirms an increasing glass transition.
