      Cover: Copper nanoparticles were made by the interaction of an argon plasma with copper species in an ionic liquid. The electrons of the free plasma reduce the dissolved metal cations at the plasma IL interface (see schematic drawing). The TEM image shows the generated nanoparticles. Further details can be found in the article by N. Kulbe, O. Höfft, A. Ulbrich, S. Zein El Abedin, S. Krischok, J. Janek, M. Pölleth, and F. Endres*on page 32.

    1. Comments Regarding ‘An Essay on Contact Angle Measurements’ (pages 14–18)

      Rosa Di Mundo and Fabio Palumbo

      Article first published online: 15 NOV 2010 | DOI: 10.1002/ppap.201000090

      This commentary addresses the contents of an essay by M. Strobel and C. S. Lyons bearing the title ‘An essay on contact angle measurements’; it is also in response to the Editors' call for a discussion on contact angle measurements in general among the readership of Plasma Processes and Polymers.

    2. Comments on “An Essay on Contact Angle Measurements” by Strobel and Lyons (pages 19–24)

      Michaela Müller and Christian Oehr

      Article first published online: 5 JAN 2011 | DOI: 10.1002/ppap.201000115

      The information that could be derived from contact angle measurements is very useful to characterize the outermost layer of a surface until it is carried out carefully. To compare the results with other working groups it is essential to describe the measurement procedure properly.

    1. Synthesis of Liquid Organic Compounds from CH4 and CO2 in a Dielectric Barrier Discharge Operating at Atmospheric Pressure (pages 25–31)

      Giorgina Scarduelli, Graziano Guella, Daniela Ascenzi and Paolo Tosi

      Article first published online: 3 JAN 2011 | DOI: 10.1002/ppap.201000044

      The conversion of methane and carbon dioxide into more useful chemicals is an important research topic. In the present paper, we discuss a multi-diagnostic investigation on the synthesis of liquid compounds by reforming methane with CO2 in a dielectric barrier discharge at atmospheric pressure.

    1. Plasma Electrochemistry in 1-Butyl-3-methylimidazolium dicyanamide: Copper Nanoparticles from CuCl and CuCl2 (pages 32–37)

      Norman Kulbe, Oliver Höfft, Angela Ulbrich, Sherif Zein El Abedin, Stefan Krischok, Jürgen Janek, Manuel Pölleth and Frank Endres

      Article first published online: 16 DEC 2010 | DOI: 10.1002/ppap.201000067

      Ionic liquids (IL) are electrolytes with a very low vapour pressure, therefore the generation of stable plasmas above the liquid surface is possible. This free plasma electrode could reduce dissolved metal cations at the plasma IL interface. The generated metal atoms could then form nanoparticles. In this paper we present our investigations on the growth of copper nanoparticles due to the interaction of an argon plasma with CuCl (CuCl2) ionic liquid solutions.

    2. Controlling the Spatial Distribution of Polymer Surface Treatment Using Atmospheric-Pressure Microplasma Jets (pages 38–50)

      Endre J. Szili, Sameer A. Al-Bataineh, Paul M. Bryant, Robert D. Short, James W. Bradley and David A. Steele

      Article first published online: 6 DEC 2010 | DOI: 10.1002/ppap.201000082

      Two different components emanating from a microplasma jet are identified: (i) a particle-based source which spreads from the orifice of the jet and (ii) a photon source, which is highly directional. A variety of microplasma jet operational parameters were adjusted to control both components, which influenced the expansion and nature of surface modification over microscopic areas of a polymer substrate.

    3. High Rate Etching of Polymers by Means of an Atmospheric Pressure Plasma Jet (pages 51–58)

      Katja Fricke, Hartmut Steffen, Thomas von Woedtke, Karsten Schröder and Klaus-Dieter Weltmann

      Article first published online: 14 DEC 2010 | DOI: 10.1002/ppap.201000093

      Etch rates of up to 300nm·s−1can be achieved using an atmospheric pressure plasma jet operating with argon and 1% oxygen admixture. Concerning the potential application of the plasma jet in biofilm removal, the etching of structurally different polymers, that represent model compounds of cell constituents, are examined. A comparison is made between argon plasma and argon with different oxygen admixtures.

    4. Atmospheric Pressure Plasma Technology: a Straightforward Deposition of Antibacterial Coatings (pages 59–69)

      S. Sarghini, S. Paulussen and H. Terryn

      Article first published online: 16 DEC 2010 | DOI: 10.1002/ppap.201000054

      Thumbnail image of graphical abstract

      In this paper, a novel procedure is explored aiming at the deposition of antibacterial coatings. SEM imaging and antibacterial tests demonstrate that the introduction of a precursor into an atmospheric pressure plasma equipment results into the homogeneous deposition of antibacterial layers. The retained antibacterial activity shows up to a 99.9999% reduction of E. coli after 24h of incubation.

    5. The Influence on Cell Growth Properties in Different Microtiterplate Types by Corona-Dielectric Barrier Discharge Plasma at Atmospheric Pressure (pages 70–76)

      Marcel Hähnel, Annette Diener, Üner Kolukisaoglu, Klaus-Dieter Weltmann and Kerstin Thurow

      Article first published online: 3 JAN 2011 | DOI: 10.1002/ppap.201000084

      Thumbnail image of graphical abstract

      Sterilization of specifically coated surfaces for cell growth by plasma can lead to loss of growth promoting properties. In this paper, a development is presented for the sterilization of microtiterplates by corona-dielectric barrier discharge plasma at atmospheric pressure. Moreover this procedure does not affect cell adhesive coatings like collagen I and poly-D-lysine.

    6. Deposition of Thin Films from Amino Group Containing Precursors with an Atmospheric Pressure Microplasma Jet (pages 77–84)

      Andreas Vogelsang, Andreas Ohl, Rüdiger Foest, Karsten Schröder and Klaus-Dieter Weltmann

      Article first published online: 29 DEC 2010 | DOI: 10.1002/ppap.201000103

      Thumbnail image of graphical abstract

      Amino-functional films with a high content of primary amino groups (up to 5.5%) were deposited, using an atmospheric pressure plasma jet. Results for the comparison of this process for two different precursors and gaseous environments are presented and first considerations regarding the polymerisation reaction are given, reflecting the various observed dependencies on the process parameters.
