3039. (I) Plasma-catalysis: From catalyst synthesis to control of plasma chemistry

Sylvain Coulombe

Symposia Day (DPP) - Plasma Physics Symposium

Invited Speaker / Conférencier(ère) invité(e)

Plasma provides the unique processing conditions for the synthesis of nanocatalysts and gas conversion, as well as the direct coupling of renewable electricity with chemical processing. Catalysis unlocks efficient reaction pathways and enables the performances necessary for process industrialization. Both combined provide unique avenues for chemical process electrification, an essential...

Symposia Day (DPP) - Plasma Physics Symposium

Invited Speaker / Conférencier(ère) invité(e)

Dielectric barrier discharges are an easy way to generate cold atmospheric pressure plasmas. For millimeter-range gas gap, a streamer breakdown generally occurs resulting in filamentary discharges. They are made of several short-lived plasma channels randomly distributed along the gas gap, which can be a serious drawback for example in the frame of surface coating processes when a homogeneous...

3387. Hydrophobic Recovery of Plasma Modified Electro-spun versus Smooth Polymer Surfaces

Cédric Pattyn

Symposia Day (DPP) - Plasma Physics Symposium

Oral (Non-Student) / Orale (non-étudiant(e))

Synthetic polymers are well known to be hydrophobic (non-wetting) in their natural state, due to their inherently low surface free energy, γ (in mN/m). Surface modification of polymers by exposure to cold plasma for enhanced wettability is practiced on vast industrial scales (i) by atmospheric pressure (AP) “corona” discharges since the 1940s; (ii) by other cold plasma processes, either at AP...

3405. (G*) Time-resolved optical emission spectroscopy of a nanosecond, pulsed microwave plasma ignited by time reversal

Mrs Amaia DRIOLLET (Université de Montréal)

Symposia Day (DPP) - Plasma Physics Symposium

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

Microwave plasmas are hugely-studied plasmas, they have characteristics that make them unique, they can be generated for low and high-pressures, they have relatively high densities of charged particles, and can be generated in different cavity geometries. A new way to ignite microwave plasmas was recently developed using time reversal and a nanosecond pulsed generator. This method allows the...

3385. (G*) Microscale electric field detection improvements: Steps toward tailoring cold atmospheric pressure plasma

Mr Justin Hogue

07/06/2022, 10:00

Symposia Day (DPP) - Plasma Physics Symposium

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

Cold atmospheric plasma science is a continuously growing domain. Agriculture, material synthesis, medicine, air and surface decontamination, food processing, among many more, applications fields of this omnipresent, yet invisible to broad society, technologies seem limitless. The knowledge about plasma sources and the underlying physics is constantly improved with new designs and...
