16 Years (2006–2021) of Surface Ozone Measurements in Córdoba (Southern Spain): Trends and the Impact of the COVID-19 Lockdown
(MDPI, 2022)Surface ozone concentrations (O3) during the period 2006–2021 are analysed at Córdoba city (southern Iberian Peninsula) in suburban and urban sampling sites. The aims are to present the levels and temporal variations, to ... -
A simple and accurate analytical model of the Stark profile and its application to plasma characterization
(Elsevier, 2018)Optical Emission Spectroscopy techniques are among the most employed to perform the characterization of laboratory plasmas. The analysis of the obtained data is based on the convolution of three different types of profiles: ... -
Accesibilidad a Internet: requisitos para la calidad en la docencia e investigación
(Universidad de Córdoba, Vicerrectorado de Innovación y Calidad Docente, 2005)A good Internet platform for teaching and research must be accessible, independently of the computer platform used, language and other peculiarities (personal or external). This work analyzes the current limitations of ... -
An experimental study of the dependence on the current intensity of the erosion of thoriated tungsten cathodes in plasma arcs
(IEEE, 2001)The erosion occurring in thoriated tungsten cathodes used in transferred plasma torches operating with current intensities ranging from 30 to 210 A has been experimentally investigated. The cathode erosion rate was determined ... -
Analysis of Alpha Activity Levels and Dependence on Meteorological Factors over a Complex Terrain in Northern Iberian Peninsula (2014–2018)
(MDPI, 2020)Alpha ambient concentrations in ground-level air were measured weekly in Bilbao (northern Spain) by collecting aerosols in filters between 2014 and 2018. Over this period, the alpha activity concentrations in the aerosol’s ... -

Atmospheric Pathways and Distance Range Analysis of Castanea Pollen Transport in Southern Spain
(MDPI, 2020)The sweet chestnut (Castanea sativa Mill.) is the only native species of this genus in Europe, where it faces various threats that are causing a severe decrease in populations, with the resulting loss of genetic diversity. ... -
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. ... -

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 ... -
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 ... -
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 ... -
