Nanostructured composites as active layer to boost cathode performance in Solid Oxide Fuel Cells
(2022-04)Since the efficiency of Solid Oxide Fuel Cells (SOFCs) is largely limited by the high polarization resistance of the cathode, several strategies have been proposed to enhance the electrochemical activity of such electrodes. ... -
Natural radiactivity from building materials in Spain
(2015-06-15)The industrial construction sector is very important in Spain. Building materials used in this industry are sources of radiation from natural radionuclides they contain. The European Commission published some recommendations ... -
Nature of the spin-glass phase in dense packings of Ising dipoles with random anisotropy axes
(2016-09-02)By Monte Carlo simulations, we study the character of the spinglass (SG) phase in dense disordered packings of magnetic nanoparticles (NPs). We focus on NPs which have large uniaxial anisotropies and can be well represented ... -
Ni-Doped PrBaFe2O5+δ As Symmetrical Electrode for Solid Oxide Cells.
(2023)The development of new redox stable electrode materials for Solid Oxide Cells (SOFs) have attracted great attention in recent years, since finding suitable compositions to operate efficiently in both fuel cell and electrolyzer ... -
El Niño as a predictor of round sardinella distribution along the northwest African coast
(2020-05-25)The El Niño Southern Oscillation (ENSO) produces global marine environment conditions that can cause changes in abundance and distribution of distant fish populations worldwide. Understanding mechanisms acting locally on ... -
Non-monotonic concentration dependence of the electro-phoretic mobility of charged spheres in realistic salt free suspensions
(AIP Publishing, 2020)Using super-heterodyne Doppler velocimetry with multiple scattering correction, we extend the optically accessible range of concen- trations in experiments on colloidal electro-kinetics. Here, we measured the electro-phoretic ... -
