Plasmon enhanced photocatalytic and antimicrobial activities of Ag-TiO2 nanocomposites under visible light irradiation prepared by DBD cold plasma treatment.

Materials Science and Engineering C: Materials for Biological Applications, 2019
Silver nanoparticles (Ag NPs) have been deposited on powder P25 by a novel two-step method involving a precipitation reaction and atmospheric pressure dielectric barrier discharge (DBD) cold plasma treatment without the use of any environmentally and ...

Quasi-stationary modeling of the DBD plasma flow control around airfoil

, 2020
This paper presents the results of numerical simulation of a dielectric barrier discharge (DBD) plasma actuator and shows its effectiveness to control air flow around the NACA(National Advisory Committee for Aeronautics)0015 airfoil.

Stimulating living cells with air DBD plasma

MRS Proceedings, 2012
ABSTRACTCells positioned at the bottom of a Petri dish were exposed, in a home-made plasma source, to pulsed Dielectric Barrier Discharges operated in air in order to investigate the effect of the plasma species on their viability and growth. Processes with different number of pulse, respectively 1,3,9 and 27 pulse, were performed to study the ...

Biomethane reforming in DBD nonequilibrium plasma

2012 Abstracts IEEE International Conference on Plasma Science, 2012
Summary form only given. There are several publications claiming to describe production of hydrogen from biogas using plasma-catalyst systems1. However, the authors has used a mixture of methane with carbon dioxide simulating a biogas but without any additives which are present in real biogas such as water vapour, H 2 S and NH 3 .

DBD modification of polyethylene powder hydrophobicity

Czechoslovak Journal of Physics, 2006
Problems of the powder particles plasma modification are practically the same as in the case of solid films. Troubles of the powder treatment are related with its three-dimensional character, small size of particles, treated large area and problems with powder manipulation, that also must not be neglected.

Synergistic degradation of trans-ferulic acid by water falling film DBD plasma coupled with cobalt oxyhydroxide: Performance and mechanisms

Chemical Engineering Journal, 2019
In this study, trans-ferulic acid (FA) was degraded by water falling film dielectric barrier discharge (DBD) plasma coupled with CoOOH catalyst. The results reveal that CoOOH improved the degradation of FA by DBD plasma through an apparent catalytic ...

Die Fraktion DBD/DFD

2000
Uber die Position der Fraktion DBD/DFD in der frei gewahlten Volkskammer der DDR kann ich nicht schreiben, ohne einleitend auf einige Zusammenhange einzugehen, die in jenen Wochen 1989/1990 und unmittelbar in den Wahlkampfen einen dominierenden Charakter trugen.

Multiprocessor Modeling of DBD Plasma Actuator

38th Fluid Dynamics Conference and Exhibit, 2008
Based on the early developed single-processor numerical model for the dielectric barrier discharge simulation we have developed a multi-processor model. The time required for the DBD simulation is shown to be significantly less for the multiprocessor model than for the single-processor one. Based on the understanding of the physics of the DBD, operated
