  1. Dynamic probing of plasma-catalytic surface processes: Oxidation of toluene on CeO2

    Toluene adsorption and oxidation on CeO2 surface by non-thermal plasma (NTP) is in situ monitored using infrared (IR) diagnostics (diffuse reflectance infrared fourier transform spectroscopy (DRIFTS) and transmission mode). The oxidation of toluene by plasma follows a first-order reaction regardless of plasma configuration and injected power. It was found that IPC was more effective for the toluene removal than PPC. Interestingly, toluene abatement and reaction intermediate formations are characterized in situ throughout the heterogeneous oxidation reaction advancement.

  2. A combined low-pressure hydrogen peroxide evaporation plus hydrogen plasma treatment method for sterilization – Part 1: Characterization of the condensation process and proof-of-concept

    Plasma sterilization is a promising alternative to conventional sterilization procedures. However, the efficiency of plasma sterilization processes is challenged by multilayered stacks of spores as plasma is a surface process. Furthermore, small, complex metal geometries pose a challenge due to shielding characteristics. A combined process of condensed hydrogen peroxide with subsequent hydrogen plasma treatment is introduced to overcome this challenges. The condensation process is investigated and a proof-of-concept is given by sterilization tests in a process challenge device and in sealed sterile bags.

  3. Solvent- and catalysts-free immobilization of tannic acid and polyvinylpyrrolidone onto PMMA surface by DBD plasma

    Surface activation polymethyl methacrylate (PMMA) by diffuse coplanar surface dielectric barrier discharge (DCSDBD) plasma unit and subsequent attachment of polyvinylpyrrolidone (PVP) and tannic acid (TAN) macromolecule layers to the surface is studied. Interaction between the two macromolecules is also analyzed by NMR.

  4. Collagen immunoassay as a method to optimise surface functionalisation

    Traditional methods of assessing surface functionalisation, including spectroscopy and chemical labelling, often involve significant error and conjecture about bonds. Proteins that improve cell attachment have specific pKa's and optimum binding requirements that may differ from the conditions required for chemical labelling. The utility of collagen ELISA to optimise acetaldehyde glow discharge polymerisation reactor parameters was tested. Accurate stepwise increases in collagen conjugation strength were demonstrated by incubating specimens in 8 M urea for 5–8 days followed by ELISA to test for residual surface collagen. Surface modifications also were assessed by XPS. The results indicated that ELISA after bond-stressing with urea may suffice for optimising surface functionalisation and that traditional methods of analysis may be superfluous if protein conjugation is the aim of functionalisation.

  5. Synthesis of supported nanocatalysts via novel non-thermal plasma methods and its application in catalytic processes

    Nowadays, promoting the chemical processes particularly by improvement of catalyst's characteristics, has drawn a lot of attention. Following this purpose, application of cold plasma in modification of catalysts has been widely under study. This paper present a review of literature relevant to different plasma treatment procedures and mechanisms. Moreover, the influences of plasma-treated catalysts on certain catalytic processes are outlined.
