The conventional synthesis of heterogeneous catalyst usually is a complex and time-consuming process. PECVD proves to be a promising technique for a one-step, and thus time and labor efficient, synthesis of heterogeneous catalysts. It is found that the catalysts, synthesized in the plasma, show basic properties, resulting in good selectivities and conversions for the isomerization of glucose into fructose.

In this study, an atmospheric pressure plasma jet is first used to generate Fe3O4nanoparticles(NPs) in liquid. The Fe3O4 NPs show excellent superparamagnetic properties and efficient imaging contrast character for magnetic resonance imaging. The stability of these NPs can be increased by adding 5% PEG in the solution. This facile, fast, environmental-friendly and economical preparation strategy for Fe3O4 NPs may open a new way for metal oxide NPs production.
- Effect of Catalyst Deactivation on Kinetics of Plasma-Catalysis for Methanol Decomposition

This paper introduces the effect of catalyst deactivation on plasma catalysis. Plasma catalysis of the methanol decomposition is introduced. Carbon deposition on catalyst alters generation of primary radical by discharge. Catalyst deactivation affects differently on catalytic function and discharge phenomena.
- Effect of the Synthesis Temperature on the Optical Indices of Organic Materials Produced by N2–CH4 RF Plasma
Ahmed Mahjoub, Nathalie Carrasco, Pierre-Richard Dahoo, Benjamin Fleury, Thomas Gautier and Guy Cernogora

This work deals with the influence of reactor temperature on optical and chemical properties of organic films produced in N2/CH4RF-plasma. We show that the plasma chemistry is drastically affected leading to the formation of polymers depleted in nitrogen containing products at low temperature. These results can be applied to the study of Titan's atmosphere and to polymers properties monitoring.
- An Insight into Grain Refinement Mechanism of Ultrananocrystalline Diamond Films Obtained by Direct Current Plasma-Assisted Chemical Vapor Deposition
Hak-Joo Lee, Jung-Min Cho, Inho Kim, Seung-Cheol Lee, Jong-Keuk Park, Young-Joon Baik and Wook-Seong Lee

The article reconciles the puzzling uniqueness of UNCD synthesis by direct current plasma-assisted CVD. UNCD films were obtained under relatively high pressure and positive substrate bias conditions using hydrogen-rich gas chemistry; similar conditions were not conducive to UNCD films when using microwave plasmas or hot filament CVDs.
