Biomass-derived carbon/γ-MnO2 nanorods/S composites prepared by facile procedures with improved performance for Li/S batteries
(Elsevier, 2018)The promising prospects of the Li/S battery, due to its theoretical energy density of about 2500 Wh kg─1, are severely limited by two main weaknesses: the poor conductivity of S and the solubility of the polysulphides ... -
Comparative study on high temperature mechanical behavior in 3YTZP containing SWCNTs or MWCNTs
(Elsevier, 2016)Effects on mechanical properties of the presence of either single-walled carbon nanotubes (SWCNTs) or multi-walled carbon nanotubes (MWCNTs) in a 3YTZP matrix have been investigated in this work. Thus, monolithic 3YTZP and ... -
Composites de carbón activado-MnO2 como electrodos para baterías de Li/S
(Universidad de Córdoba, 2019)El presente trabajo se ha centrado en el estudio de materiales basados en carbón activado y dióxido de manganeso en la fase γ-MnO2 como aditivos de electrodos para baterías Li/S. El MnO2 se preparó en forma de microesferas ... -
Creep study on alumina and alumina/SWCNT nanocomposites
(Elsevier, 2018)Alumina and alumina/SWCNT nanocomposites have been sintered by spark plasma sintering, obtaining relative densities higher than 99%. Microstuctural characterization revealed a grain microstructure in the submicron range, ... -
Electrocatalizadores bifuncionales basados en grafeno dopado con N y modificados con Ti y Co para pilas de combustible regenerativas en una unidad
(Universidad de Córdoba, UCOPress, 2021)El aumento de la demanda energética que ha experimentado la humanidad en los últimos años, sumado al incesante avance del calentamiento global asociado al uso de combustibles fósiles como principal fuente de energía, han ... -
Electroconductive Composites from Polystyrene Block Copolymers and Cu–Alumina Filler
(MDPI, 2016)Technological advancements and development of new materials may lead to the manufacture of sustainable energy-conducting devices used in the energy sector. This research attempts to fabricate novel electroconductive and ... -
High-temperature deformation mechanisms in monolithic 3YTZP and 3YTZP containing single-walled carbon nanotubes
(Wiley, 2015)Monolithic 3YTZP and 3YTZP containing 2.5 vol% of single-walled carbon nanotubes (SWCNT) were fabricated by Spark Plasma Sintering (SPS) at 1250°C. Microstructural characterization of the as-fabricated 3YTZP/SWCNTs composite ... -
Modification of layered cathodes of sodium-ion batteries with conducting polymers
(MDPI, 2024)Layered oxides exhibit interesting performance as positive electrodes for commercial sodium-ion batteries. Nevertheless, the replacement of low-sustainable nickel with more abundant iron would be desirable. Although it can ... -
