Low Electron Temperature Plasma Diagnosis: Revisiting Langmuir Electrostatic Probes
(MDPI, 2021)This article describes a method of measurement of the current-to-probe voltage characteristic curve of a Langmuir electrostatic probe immersed in a plasma characterized by a low electron temperature that is only one order ... -
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 ... -
Method of Moments Optimization of Distributed Raman Amplification in Fibers with Randomly Variying Birefringence
(MDPI, 2020)In this work, we develop a vectorial model, for optical communications, using distributed Raman amplification (DRA) applied to vectorial soliton pulses in monomode fiber optics. The main result, a dependent polarization ... -
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 ... -
On the impact of wavelength dependency on supercontinuum generation in photonic crystal fibers
(MDPI, 2024)It is common practice when simulating propagation through an optical fiber to assume that its characteristic parameters are constant and determined solely by the central wavelength of the input pulse. In this paper, we ... -
On- and off-center helium atom in a spherical multilayer quantum dot with parabolic confinement
(Springer, 2023)The ground state energy of a helium atom inside a spherical multilayer quantum dot as a function of the atomic impurity location inside the quantum dot has been calculated. The multilayer quantum dot is modeled by a ... -
Optimizing high-quality graphene nanoflakes production through organic (bio)-precursor plasma decomposition
(Elsevier, 2021)Atmospheric pressure plasma-based technique for the decomposition of biofuels allows obtaining high-quality graphene powder in one step, without the use of neither metal catalysts nor specific substrates. Despite the ... -
Photon to axion conversion during Big Bang Nucleosynthesis
(IOP Publishing, 2023)We investigate how the resonant conversion at a temperature T¯=25-65 keV of a fraction of the CMB photons into an axion-like majoron affects BBN. The scenario, that assumes the presence of a primordial magnetic field and ... -
Polarization Properties of Laser Solitons
(MDPI, 2017)The objective of this paper is to summarize the results obtained for the state of polarization in the emission of a vertical-cavity surface-emitting laser with frequency-selective feedback added. We start our research with ... -

Quantitative comparison of impurity transport in turbulence reduced and enhanced scenarios at Wendelstein 7-X
(IOP Publishing, 2023)We assess the turbulent particle transport being responsible for the limitation of the confinement and, thus, the overall performance of the neoclassically optimized stellarator Wendelstein 7-X. The radial particle transport ... -
Quantum defect asymptotics at the critical charge: A study of the integrality conjecture
(Elsevier, 2018)A single (n, ℓ) electron outside an (N −1)-electron atomic core is bound as long as Z > Zc = N − 1. A conjecture is examined, according to which the quantum defect of the outermost electron satisfies limZ!Zc δn,ℓ(Z) = Nℓ, ... -

Simple and analytical function for the Stark profile of the Hα line and its application to plasma characterization
(Elsevier, 2018)The increasing application of plasma based technologies over a wide range of fields has led to the necessity of an optimal determination of the characteristic parameters of the plasma systems. Optical Emission Spectroscopy ... -
Singlet vs. triplet interelectronic repulsion in confined atoms
(Elsevier, 2018)Hund’s multiplicity rule invariably holds for the ground configurations of few-electron atoms as well as those of multi-electron quantum dots. However, the ordering of the corresponding interelectronic repulsions exhibits ... -
Software público, libre, abierto, gratuito, privativo y comercial para la innovación y mejora de la calidad en la docencia, investigación, gestión y asistencia
(Universidad de Córdoba, Vicerrectorado de Innovación y Calidad Docente, 2007)The public free software (now renamed as open software) is the basis of the open source software (OSS) project. This initiative promotes the use of open standards and platform-independent accessibility. Many OSS products ... -
Spatial Distribution of Wettability in Aluminum Surfaces Treated with an Atmospheric-Pressure Remote-Plasma
(MDPI, 2019)The use of atmospheric-pressure remote plasmas (postdischarge) sustained in argon and argon–nitrogen for the treatment of aluminum surfaces has been studied to better understand the underlying mechanisms responsible for ... -
Spectral Methods in Nonlinear Optics Equations for Non-Uniform Grids Using an Accelerated NFFT Scheme
(MDPI, 2023)In this work, we propose the use of non-homogeneous grids in 1D and 2D for the study of various nonlinear physical equations using spectral methods. As is well known, the use of spectral methods allow a faster resolution ... -
Stability after confinement of the H atom
(Elsevier, 2019)The stability of a spherically confined atomic system when confinement is removed is studied. We consider s, p, d, and f states of the Hydrogen atom confined by a finite barrier. The stability is characterized in terms of ...
