    Assessment of the suitability of the chemical reaction pathway algorithm as a reduction method for plasma chemistry
    (Bristol : IOP Publ., 2022) Tadayon Mousavi, S.; Gulpen, J.G.M.; Graef, W.A.A.D.; Koelman, P.M.J.; Carbone, E.A.D.; van Dijk, J.
    Determination of chemical pathways, sets of interlinked reactions, is a well-known method to study complex chemistries. In order to have a trustworthy and accurate method for analysis of chemical processes in complicated systems such as low-temperature plasmas, a used algorithm should keep conservation of necessary parameters during all steps of an analysis. In this research, the introduced algorithm by Lehmann (2004 J. Atmos. Chem. 47 45-78) is chosen as a candidate for studying tangled low-temperature plasma chemistry. As a first step, the ability of the algorithm to keep conservation of reactions rates and net production of species is assessed by designing some artificial examples. In that stage, ambiguous parts of the algorithm are clarified, and test cases are provided to verify implementation of the algorithm in any programming infrastructure. Then, the capability of the algorithm as a reduction method is investigated by applying a newly developed semi-automated method based on pathway analysis to two plasma chemistry examples, a H 2 O - H e microwave induced plasma and a pulsed H 2 plasma.

    Plasma medicine: An introductory review
    ([London] : IOP, 2009) Kong, M. G.; Kroesen, G.; Morfill, G.; Nosenko, T.; Shimizu, T.; van Dijk, J.; Zimmermann, J. L.
    This introductory review on plasma health care is intended to provide the interested reader with a summary of the current status of this emerging field, its scope, and its broad interdisciplinary approach, ranging from plasma physics, chemistry and technology, to microbiology, biochemistry, biophysics, medicine and hygiene. Apart from the basic plasma processes and the restrictions and requirements set by international health standards, the review focuses on plasma interaction with prokaryotic cells (bacteria), eukaryotic cells (mammalian cells), cell membranes, DNA etc. In so doing, some of the unfamiliar terminology-an unavoidable by-product of interdisciplinary research-is covered and explained. Plasma health care may provide a fast and efficient new path for effective hospital (and other public buildings) hygiene-helping to prevent and contain diseases that are continuously gaining ground as resistance of pathogens to antibiotics grows. The delivery of medically active 'substances' at the molecular or ionic level is another exciting topic of research through effects on cell walls (permeabilization), cell excitation (paracrine action) and the introduction of reactive species into cell cytoplasm. Electric fields, charging of surfaces, current flows etc can also affect tissue in a controlled way. The field is young and hopes are high. It is fitting to cover the beginnings in New Journal of Physics, since it is the physics (and nonequilibrium chemistry) of room temperature atmospheric pressure plasmas that have made this development of plasma health care possible. © IOP Publishing Ltd and Deutsche Physikalische Gesellschaft.
