    In this work, a microwave surfaguide discharge operating at 2.45 GHz in several CO2-containing mixtures is investigated. Among various useful applications, these sources are considered to be energy-efficient and powerful plasma-chemical systems in gas reforming. This subject is highly important nowadays due to the growing interest to plasma-based CO2 decomposition. We used optical emission spectroscopy and two-photon absorption laser-induced fluorescence to study plasma-assisted CO2 conversion in relation with plasma parameters, such as electron and gas temperature, etc. The current paper is targeted to demonstrate a potential for optimization of the pulsed microwave discharges for increasing the CO2 decomposition efficiency as well as to show an importance of the optical diagnostic methods for characterization of various physical and chemical mechanisms related to CO2 plasmas.

    Cold atmospheric plasma generated in deionized water has potential to be noninvasively delivered, combined with other drugs or used as standalone drug and injected into tumors.

  3. Redox-regulation of activator protein 1 family members in blood cancer cell lines exposed to cold physical plasma-treated medium

    Activator protein 1 family members regulate gene expression which are important in redox signaling responses. Exposure to cold physical plasma-treated medium significantly alters the expression of AP-1 transcription factor subunits such as FOSB, JUND, and EGR1 in Jurkat and THP-1 cells. These factors induce target gene expression of anti-oxidant response, DNA repair, cell-cycle progression, and apoptosis. Activation states of AP-1 signaling cascades in plasma-treated leukemia cells support potential of cold plasma in cancer therapy.

  4. Synergy of DBD plasma and Fe-based catalyst in NH3 decomposition: Plasma enhancing adsorption step

    The mechanism of synergy between plasma and catalyst is unclear. This paper provides a direct proof that the electronically excited state NH3 (NH3*) can adsorb on the Fe-based catalyst with higher adsorption capacity and stronger strength than that of the ground state NH3. Therefore, plasma-enhancing adsorption step as being observed herein should be one of the synergistic ways of plasma with heterogeneous catalyst.
