An investigation of an underwater steam plasma discharge as alternative to air plasmas for water purification
Gucker, Sarah N.; Foster, John E.; García, María C (IOP Publishing, 2015)An underwater steam plasma discharge, in which water itself is the ionizing media, is investigated as a means to introduce advanced oxidation species into contaminated water for the purpose of water purification. The steam ... -
Microwave atmospheric pressure plasma jets for wastewater treatment: Degradation of methylene blue as a model dye
García, María C; Mora, Manuel; Esquivel, Dolores; Foster, John E.; Rodero Serrano, Antonio; Jiménez-Sanchidrián, César; Romero-Salguero, F.J (Elsevier, 2017)The degradation of methylene blue in aqueous solution as a model dye using a non thermal microwave (2.45 GHz) plasma jet at atmospheric pressure has been investigated. Argon has been used as feed gas and aqueous solutions ... -
Optical Emission Spectroscopy Investigation of a 1-atm DC Glow Discharge With Liquid Anode and Associated Self-Organization Patterns
Kovach, Yao E.; García, María C; Foster, John E. (IEEE, 2019)Optical emission spectroscopy is used to study a 1-atm dc helium glow discharge with a liquid anode to obtain insight into the physical mechanisms underlying observed plasma self-organization at the liquid surface. Plasma ... -
Promise of nonthermal plasmas in addressing emerging environmental and health problems: Present and future
Foster, John E.; García, María C (AIP Publishing, 2022)Nonthermal atmospheric pressure plasmas transform input electrical energy efficiently into reactive species, charged particles, and photons. This “activated gas” is being investigated as solutions for a range of environmental ... -
Self-organization in 1 atm DC glows with liquid anodes: current understanding and potential applications
Foster, John E.; Kovach, Yao E.; Lai, Janis; García, María C (IOP Publishing, 2020)Self-organization refers to the spontaneous generation of spatially or temporally organized patterns in an otherwise disordered system. Self-organization is ubiquitous in plasma physics particularly in the low-pressure ... -
The variation in self-organized anode plasma pattern structure with solution electrolyte type in 1 atm DC glow discharge
Kovach, Yao E.; García, María C; Foster, John E. (IOP Publishing, 2021)Plasma self-organization on anode surfaces in 1 atm DC glow discharges remains poorly understood. This effort aims to elucidate the nature of self-organization through the experimental study of resulting patterns on liquid ... -
Understanding the plasma and power characteristics of a self-generated steam bubble discharge
García, María C; Gucker, Sarah N.; Foster, John E. (IOP Publishing, 2015)Plasma formation in a self-generated steam bubble is studied using a coaxial discharge tube with an axial powered electrode (nominal peak operating voltage 2000 V) and an external ground lead without any gas flow. The ...
