Reduced HeLa cell viability in methionine‐containing cell culture medium irradiated with microwave‐excited atmospheric‐pressure plasma

19-Jan-2018 | Yohei Takahashi, Yusuke Taki, Keigo Takeda, Hiroshi Hashizume, Hiromasa Tanaka, Kenji Ishikawa, Masaru Hori, Plasma Processes and Polymers, 2018

The mechanism underlying the death of cancer cells incubated in plasma‐activated medium (PAM) prepared by irradiation of culture medium with atmospheric‐pressure plasma is revealed by analyzing changes in the culture medium composition using liquid chromatography‐tandem mass spectrometry and ...

Removal of persistent organic pollutants from water using a newly developed atmospheric plasma reactor

18-Jan-2018 | Francesco Tampieri, Agata Giardina, Franco J. Bosi, Alice Pavanello, Ester Marotta, Barbara Zaniol, Gabriele Neretti ..., Plasma Processes and Polymers, 2018

A new bench‐top reactor employing a streamer discharge in air was developed and tested for potential use in an advanced oxidation stage in water treatment processes. The complex heterogeneous system and the ensuing chemical processes were characterized using an integrated approach to map the ...

Decolorization of organic dyes solution by atmospheric pressure glow discharge system working in a liquid flow‐through mode

07-Sep-2017 | Piotr Jamroz, Anna Dzimitrowicz, Pawel Pohl, Plasma Processes and Polymers, 2017

A new atmospheric pressure glow discharge (APGD) plasma‐reaction system generated between a flowing liquid electrode and an Ar microjet nozzle is applied to decompose various organic dyes. The APGD system is working in a flow‐through mode in an open to air atmosphere. Degradation of the organic ...

Effects of atmospheric pressure plasma generated in GlidArc reactor on Lavatera thuringiaca L. seeds’ germination

07-Sep-2017 | Joanna Pawlat, Agnieszka Starek, Agnieszka Sujak, Michał Kwiatkowski, Piotr Terebun, Małgorzata Budzeń, Plasma Processes and Polymers, 2017

The paper presents experimental results concerning pre‐sowing stimulation of Thuringian Mallow (Lavatera thuringiaca L.) seeds with non‐thermal plasma generated in GlidArc reactor (dry nitrogen, atmospheric pressure) and its effect on the germination process. Five groups of seeds characterized ...

The influence of plasma operation parameters on synthesis process of copper particles at atmospheric pressure

04-Sep-2017 | Valentina Marascu, Andrada Lazea‐Stoyanova, Cristian Stancu, Gheorghe Dinescu, Plasma Processes and Polymers, 2017

Copper particles, generated using an atmospheric pressure plasma jet (APPJ), are characterized and their generation is studied. The particle synthesis is based on the vaporization/condensation process. In our study, we used a radiofrequency (RF) plasma jet operating in an inert gas and copper ...

Generation of energetic electrons in pulsed microwave plasmas

01-Sep-2017 | Min Uk Lee, Jae Koo Lee, Gunsu S. Yun, Plasma Processes and Polymers, 2017

Pulsed microwave driven microplasma at atmospheric pressure is proposed as an efficient source of energetic electrons for low‐temperature biomedical applications. Energetic electrons are required to break the covalent bonds of nitrogen, oxygen, and water molecules in humid air and produce ...

Changes in Norway spruce germination and growth induced by pre‐sowing seed treatment with cold plasma and electromagnetic field: Short‐term versus long‐term effects

29-Aug-2017 | Giedre Pauzaite, Asta Malakauskiene, Zita Nauciene, Rasa Zukiene, Irina Filatova, Veronika Lyushkevich, Igor Azarko, ..., Plasma Processes and Polymers, 2017

The effects of Norway spruce (Picea abies) seed treatment with cold plasma (CP), vacuum, and electromagnetic field (EMF) on germination and seedling growth are studied. CP treatments negatively affected germination ‘in vitro’, but for germination in cassettes CP (7 min) and EMF (5 min) ...

Direct plasma stimuli including electrostimulation and OH radical induce transient increase in intracellular Ca2+ and uptake of a middle‐size membrane‐impermeable molecule

25-Aug-2017 | Shota Sasaki, Yutaro Hokari, Akiko Kumada, Makoto Kanzaki, Toshiro Kaneko, Plasma Processes and Polymers, 2017

Despite the promising potential of medical treatments based on non‐equilibrium atmospheric‐pressure plasma, most of the underlying mechanisms remain unknown. Here we report that direct plasma irradiation (DPI) can induce transient increase in intracellular calcium (Ca2+) concentrations, thereby ...

Translation of plasma technology from the lab to the food industry

23-Aug-2017 | Patrick J. Cullen, James Lalor, Laurence Scally, Daniela Boehm, Vladimir Milosavljević, Paula Bourke, Kevin Keener, Plasma Processes and Polymers, 2017

The potential of cold plasma as a food processing aid has been demonstrated for a range of processes and products. The potential applications of plasma technology are extensive and include microbial decontamination, pest control, toxin elimination, food and package functionalisation and many ...

On the non‐thermal plasma synthesis of nickel nanoparticles

23-Aug-2017 | Austin Woodard, Lihua Xu, Alejandro A. Barragan, Giorgio Nava, Bryan M. Wong, Lorenzo Mangolini, Plasma Processes and Polymers, 2017

Nickel (Ni) nanoparticles have been synthesized from the dissociation of nickelocene (Ni(Cp)2) in an argon‐hydrogen (Ar‐H2) low pressure continuous‐flow non‐thermal plasma. The influence of process parameters on the synthesized Ni nanomaterial structure, size, size‐dispersion, and carbon ...
