Measuring the air fraction and the gas temperature in non-thermal argon plasma jets through the study of the air influence on the collisional broadening of some argon atomic emission lines
(IOP Publishing, 2020)
Cold atmospheric argon plasma jets have shown to be very promising in medicine and they are being currently used for therapeutical uses such as the healing of wounds or the treatment of tumors. Because they run in the open ...
Microwave atmospheric pressure plasma jets for wastewater treatment: Degradation of methylene blue as a model dye
(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 ...
Characterization of an Air-Based Coaxial Dielectric Barrier Discharge Plasma Source for Biofilm Eradication
(Springer, 2018)
Air-based atmospheric-pressure cold plasmas are a source of charged particles, excited species, radicals, and UV rays, known to induce degradation of biomaterials. In this work we characterize an air-based Dielectric Barrier ...
Application of LIBS technology for determination of Cl concentrations in mortar samples
(Elsevier, 2019)
In a society where the cement and concrete industry is of great importance, the diagnosis of the quality of these materials has become a matter of highest priority. One of the maximum exponents of the deterioration of a ...
Gas temperature determination of non-thermal atmospheric plasmas from the collisional broadening of argon atomic emission lines
(Elsevier, 2017)
In this work we propose a new method allowing gas temperature determination in argon non-thermal plasma jets, based on the measurement of the collisional broadening of different argon atomic lines corresponding to transitions ...
Study of the plasma–liquid interaction for an argon nonthermal microwave plasma jet from the analysis of benzene degradation
(Wiley, 2020)
The interaction of an argon microwave plasma jet with a benzene layer on water has been analyzed under different conditions (power, gas flow, plasma-sample distance, and treatment time) in this study. Main products formed ...
Using laser-induced breakdown spectroscopy for the study of chloride diffusion in mortar and concrete
(Elsevier, 2023)
In this work, the applicability of Laser-Induced Breakdown Spectroscopy (LIBS) for the analysis of chloride
diffusion in mortar and concrete has been studied. The high resolution of this technique allows it to obtain a ...
Gas temperature and air fraction diagnosis of helium cold atmospheric plasmas by means of atomic emission lines
(Elsevier, 2022)
In this work, we present a new method allowing the determination of both the gas temperature and the air
fraction in non-thermal atmospheric helium plasmas. This new UV-Atomic Emission Spectroscopy technique based on the ...
Gas temperature determination in an argon non-thermal plasma at atmospheric pressure from broadenings of atomic emission lines
(Elsevier, 2017)
In this work a new spectroscopic method, allowing gas temperature determination in argon non-thermal plasmas sustained at atmospheric pressure, is presented. The method is based on the measurements of selected pairs of ...
