CO Generation from CO2 Using an Atmospheric Microwave Plasma Process
Chemie Ingenieur Technik, EarlyView.Due to the increasing concentration of CO2 in the atmosphere and the resulting man‐made climate change, alternatives to fossil fuels must be found. The chemical industry is looking for alternative processes. One promising possibility is atmospheric pressure microwave plasma, which converts CO2 into CO using electrical energy.

Synthesis of Membrane-Electrode Assembly for Fuel Cells by Means of (Sub)-Atmospheric Plasma Processes [PDF]
Plasma Processes & Polymers, 2012, Vol. 9, Issue 11-12, 1144-1153, 2018 An easy procedure to build up membrane-electrode assemblies for applications dedicated to miniaturized PEMFC using H2 or CH3OH by a two-steps atmospheric plasma process is reported. Firstly, catalyst nanoparticles are grafted on carbon substrates by spraying a Pt colloidal solution in the post-discharge of an RF atmospheric plasma torch.

Novel Microwave Plasma Source for Plasma Chemistry in Gases
Chemie Ingenieur Technik, EarlyView.A new microwave plasma source for plasma gas chemistry is introduced. Microwave energy is specifically coupled into defined gas volumes to activate chemically internal compounds such as N2, CO2 or H2O. The activation of N2 and the conversion of CO2 to CO are given as examples.

In-depth diffusion of oxygen into LDPE exposed to an Ar--O2 atmospheric post-discharge: a complementary approach between AR-XPS and Tof-SIMS techniques [PDF]
Surface and Interface Analysis, Wiley-Blackwell, 2014, 46 (3),
pp.164-174, 2016 The in-depth oxygen diffusion into a low density polyethylene film is performed in the post-discharge of an atmospheric plasma torch, supplied in argon as carrier gas and with or without oxygen as reactive gas. The chemical and structural properties of the polymer surface and bulk are studied in terms of plasma parameters (treatment time, power, and ...

Competitive and synergistic effects between excimer VUV radiation and O radicals on the etching mechanisms of polyethylene and fluoropolymer surfaces treated by atmospheric He-O$_2$ post-discharge [PDF]
J. Phys. D: Appl. Phys., 2013, Vol. 46, Issue 31, 315203 (14 pp), 2016 Among various surface modification techniques, plasma can be used as a source for tailoring the surface properties of diverse materials. HDPE and fluoropolymer surfaces have been treated by the post-discharge of an atmospheric RF-plasma torch supplied with helium and oxygen gases.
