- Performances Enhancement of H-Doped ZnO Nanorods by H2/Ar Plasma Treatment

Luminescence and electrical conductivities of ZnO can be significantly enhanced by doping with hydrogen, but then substantially decline upon being exposed to heat due to the instability of H dopants. To increase the thermal stability of H dopants and enhanced optoelectronic properties, a H2/Ar mixed plasma treatment is employed to modify ZnO nanorods.

The use of non-thermal plasmas can bring great advantages to traditional wet methods employed in different textile materials and processes without modifying the bulk properties of a large spectrum of materials. Recently, atmospheric plasmas have been effectively employed as a suitable alternative to low-pressure plasma, allowing continuous and uniform processing of fibres surfaces.
- Cathodic Contact Glow Discharge Electrolysis for the Degradation of Liquid Ammonia Solutions
Anis Allagui, Nicolas Brazeau, Hussain Alawadhi, Fares Al-momani and Elena A. Baranova
Article first published online: 22 AUG 2014 | DOI: 10.1002/ppap.201400049
Above a critical terminal voltage between a small cathode and a large anode, the electrolyte breakdown leads to contact glow discharge electrolysis. The process degrades ammonia in part by nitrification thanks to the powerful generated oxidizing species (OH·, O·, etc.), at 12% per hour with 0.28 mol/kW h energy efficiency, and following pseudo first-order kinetics.
- Single Step Plasma Deposition of Platinum-Fluorocarbon Nanocomposite Films as Electrocatalysts of Interest for Micro Fuel Cells Technology
Antonella Milella, Fabio Palumbo, Elena Dilonardo, Gianni Barucca, Pinalysa Cosma and Francesco Fracassi
Article first published online: 22 AUG 2014 | DOI: 10.1002/ppap.201400039
Pt/fluorocarbon nanocomposite coatings were deposited from a combined PECVD and sputtering process. A comprehensive chemical and morphological characterization is presented. Such materials show interesting electrocatalytic activity towards hydrogen oxidation reaction, which makes them promising for application in micro fuel cell technology.
- Atmospheric Pressure Plasma Initiated Chemical Vapor Deposition Using Ultra-Short Square Pulse Dielectric Barrier Discharge
Nicolas D. Boscher, Florian Hilt, David Duday, Gilles Frache, Thierry Fouquet and Patrick Choquet
Article first published online: 22 AUG 2014 | DOI: 10.1002/ppap.201400094
The atmospheric pressure plasma initiated chemical vapor deposition of conventional polymer is described. Polymer molecular weights up to 30 000 g mol−1, measured by size exclusion chromatography (SEC), are achieved thanks to the use of an ultra-short square pulse dielectric barrier discharge. The polymer structure of the thin films is evidenced by matrix-assisted laser desorption/ionization high-resolution mass spectrometry.
