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 ... -
Confinement in electron heated plasmas in Wendelstein 7-X and ASDEX Upgrade; the necessity to control turbulent transport
(2021)In electron (cyclotron) heated plasmas, in both ASDEX Upgrade (L-mode) and Wendelstein 7-X, clamping of the ion temperature occurs at Ti ∼ 1.5 keV independent of magnetic configuration. The ions in such plasmas are heated ... -
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 ... -
Data on Stark Broadening of Sn II Spectral Lines
(MDPI, 2025)Data on spectral line widths and shifts broadened by interactions with charged particles, for 44 lines in the spectrum of ionized tin, for collisions with electrons and H II and HeII ions, are presented as online available ... -
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 ... -
Determinación de la constante de Hubble mediante observaciones del Universo Local
(Real Sociedad Española de Física, 2020-04)En este trabajo se ofrece el resultado de una determinación directa de la constante de Hubble H0 a partir de observaciones del Universo Local. Para ello hemos usado la técnica de la escalera cósmica de distancias siguiendo ... -
Determination of Physicochemical Water Quality of the Ghis-Nekor Aquifer (Al Hoceima, Morocco) Using Hydrochemistry, Multiple Isotopic Tracers, and the Geographical Information System (GIS)
(MDPI Academic Editor: Dimitrios E. Alexakis, 2022-02-22)The chemical characterization of the Ghis-Nekor groundwater has become a concern of many researchers in Morocco. It is a crucial indicator for the environment situation and the socioeconomic development of this Moroccan ... -
Diffusion Monte Carlo calculation of fully heavy pentaquarks
(American Physical Society, 2024)Using a diffusion Monte Carlo algorithm, we calculated the spectra of all possible S-wave fully heavy pentaquarks within the framework of the quark model. Our aim was to compare the masses of different spin-color ... -
Diffusion Monte Carlo calculations of fully heavy compact hexaquarks
(American Physical Society, 2022)We used a diffusion Monte Carlo technique to describe the properties of fully heavy compact arrangements (no dibaryon molecules) including six quarks and no antiquarks within the framework of a constituent quark model. ... -
Diffusion Monte Carlo description of Cs2–(4He)N clusters: an example of weak dopant–helium interaction
(Institute of Physics, 2011)In this paper, we study the energy and geometric properties of Cs2–(4He)N clusters, 2 <= N <= 20, N even, through a diffusion Monte Carlo methodology. Considering the results for doped clusters in which the He–impurity ... -
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 ... -
Efficiency of a solar collector system for the public building depending on its location
(Springer, 2019)Due to a technologic progress, a growth in the renewable energy markets including a high number of manufactures coming to being, the Renewable Energy Sources (RES) are both a tool for mitigating climate changes and investments ... -
Electrostatic gyrokinetic simulations in Wendelstein 7-X geometry: benchmark between the codes stella and GENE
