  1. A Novel Insight on the Geometry of Plasma Channels of Nanosecond Micron-Size Discharges on the Surface of Living Tissues of Plants

    Julia P. Kozhayeva, Valeria A. Lyubimtseva, Elena A. Zuimatch and Alexander E. Dubinov

    Article first published online: 30 OCT 2014 | DOI: 10.1002/ppap.201400132

    A chip for generating nanosecond surface micron-size discharges is described. Results of observations of their interaction with surfaces of living tissues of plants are presented. It was found that the trajectories of plasma channels follow intercellular walls and have a zigzag shape. It was also identified that a single discharge results in destruction of cell wall, which stimulates juice excretion.

  2. From Killing Bacteria to Destroying Cancer Cells: 20 Years of Plasma Medicine

    Mounir Laroussi

    Article first published online: 28 OCT 2014 | DOI: 10.1002/ppap.201400152

    This is an essay that briefly reviews and discusses the application of low temperature plasma (LTP) to kill cancer cells. Some historical background is given and the views and opinions of the author about the present and future of the field are presented.

  3. Polymer Powder Treatment in Atmospheric Pressure Plasma Circulating Fluidized Bed Reactor

    Gina Oberbossel, Andreas Thomas Güntner, Lukas Kündig, Christian Roth and Philipp Rudolf von Rohr

    Article first published online: 28 OCT 2014 | DOI: 10.1002/ppap.201400124

    A remote atmospheric pressure plasma process capable of activating fine-grained polymer powders is presented. Plasma treated HDPE powder reveals a decrease in benzyl alcohol contact angle. Influence of treatment time and used process gas mixtures on contact angle measurements as well as effect of powder conveying on particle size distribution are discussed.

  4. Amination of NCD Films for Possible Application in Biosensing

    Anna Artemenko, Halyna Kozak, Hynek Biederman, Andrei Choukourov and Alexander Kromka

    Article first published online: 28 OCT 2014 | DOI: 10.1002/ppap.201400151

    H- and O-terminated NCD films are functionalized by deposition of amine containing plasma polymer and RF plasma treatment in NH3. The concentrations of [BOND]NH2 groups about 5 and 1% are obtained on diamond surfaces, respectively. IV measurements show the destruction of H-NCD surface conductivity after plasma treatment. After amination via polymer it decreases down to 10−7 S.

  5. Fabrication, Characterization, and Comparison of Oxygen-Rich Organic Films Deposited by Plasma- and Vacuum-Ultraviolet (VUV) Photo-Polymerization

    Juan-Carlos Ruiz, Pierre-Luc Girard-Lauriault and Michael R. Wertheimer

    Article first published online: 20 OCT 2014 | DOI: 10.1002/ppap.201400146

    Thin O-containing films were produced by vacuum-ultraviolet (VUV) photo-polymerization or by low-pressure r.f. plasma-assisted CVD, using ethylene (C2H4) with one of several O-containing oxidizer molecules, O2, CO2, or N2O. Analyses were performed by XPS (with or without chemical derivatization using TFAA to determine [[BOND]OH] content), and by IRRAS-FTIR. Nominally similar coatings displayed rather different structures and characteristics.
