Carbon Black as Conductive Additive and Structural Director of Porous Carbon Gels
(MDPI, 2020)This work investigates the impact of carbon black (CB) as a porogenic agent and conductive additive in the preparation of electrically conductive nanoporous carbon gels. For this, a series of materials were prepared by the ... -
Carbon Dioxide Decomposition by a Parallel-Plate Plasma Reactor: Experiments and 2-D Modelling
(MDPI, 2021)The applicability of high voltage electrical discharges for the decomposition of CO2 has been extensively demonstrated. In this study, a new AC parallel-plate plasma reactor is presented which was designed for this purpose. ... -
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 ... -
Clinical and Biological Principles of Cold Atmospheric Plasma Application in Skin Cancer
(Springer, 2016)Plasma-based electrosurgical devices have long been employed for tissue coagulation, cutting, desiccation, and cauterizing. Despite their clinical benefits, these technologies involve tissue heating and their effects are ... -
Complementos pedagógicos para la enseñanza de la Teoría Cuántica en Física y su adecuación a la metodología del Espacio Europeo de Educación Superior

Confined orbitals in fullerenes and quantum dots calculated by analytic continuation method
(Springer, 2021)The Schrödinger equation with a Gaussian potential to model a confined system as a quantum dot or a hydrogen atom inside a fullerene is solved by using the analytic continuation method. The use of the Rodrigues formula ... -
Cosmology of an axion-like majoron
(IOP Publishing, 2022)We propose a singlet majoron model that defines an inverse seesaw mechanism in the ν sector. The majoron ϕ has a mass mϕ ≈ 0.5 eV and a coupling to the τ lepton similar to the one to neutrinos. In the early universe it is ... -
Design of multivariable PID control using iterative linear programming and decoupling
(MDPI, 2024)The design of multivariable process control systems is specially complicated when there are strong interactions between the different control loops, and even more with multiple time delays. This paper proposes an iterative ... -
Effects of size on the spectrum and stability of a confined on-center Hydrogen atom
(IOP Publishing, 2022)In this work we studied the problem of the stability of confined atoms when they are released from confinement. We analyzed the confined Hydrogen atom inside a cage modelled by a square-well potential, in particular the ... -
Estudio del impacto de un cuestionario de autoevaluación online para el tratamiento de errores experimentales
(UCOPress, 2019)La correcta comprensión del origen de las incertidumbres experimentales, así como su tratamiento matemático, resulta fundamental en la formación de cualquier científico, pues permite determinar la precisión de los resultados ... -
Evidence for baryon acoustic oscillations from galaxy–ellipticity correlations
(Springer, 2023)The Baryon Acoustic Oscillations (BAO) feature in the clustering of galaxies or quasars provides a "standard ruler" for distance measurements in cosmology. In this work, we report a 2∼3σ signal of the BAO dip feature in ... -
Exclusion Principle Repulsion Effects on the Covalent Bond Beyond the Born-Oppenheimer Approximation
(Royal Society of Chemistry, 2019)The changes in the covalent bond of the hydrogen molecule limited in the space by a spherical hard boundary are studied. The sphere is moved along an axis parallel or orthogonal to the molecular axis. The diffusion Monte ... -
Experimental Study of a Rotating Electrode Plasma Reactor for Hydrogen Production from Liquid Petroleum Gas Conversion
(MDPI, 2022)In this work, a new plasma reactor operating with a butane/propane (C4H10/C3H8) gaseous mixture, designed for hydrogen molecule production, was experimentally studied. This reactor is based on a rotating electrode, biased ... -
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 microwave discharges at atmospheric pressure by using different Optical Emission Spectroscopy techniques
(Elsevier, 2013)Non-thermal plasmas sustained at atmospheric pressure are considered as a very promising technology for different purposes, in which the knowledge of the gas temperature is an important issue. In this paper, the gas ... -

Ionization and excitation probabilities of a hydrogen atom suddenly released from penetrable confinement
(Taylor & Francis, 2018)The problem of the stability of the hydrogen atom when it is released from a confining environment is studied. The stability is analysed in terms of excitation and ionization probabilities of the final state for different ... -
Ionization probability of the hydrogen atom suddenly released from confinement
(Wiley, 2017)The problem of the stability of a confined atom when it is extracted from the confining cavity has been investigated, modeled by a spherical hard wall potential. The ionization probability when the atom is released from ... -
