Carbajo-Coronado, Blanca; Moreno-Sandoval, Antonio; Torterolo Orta, Yanco Amor; Gozalo, Paula, 2025, "The Financial Document Causality Detection Shared Task (FinCausal 2025): Dataset", https://doi.org/10.21950/V8VSSO, e-cienciaDatos, V1
The Financial Document Causality Detection Shared Task (FinCausal 2025) aims to improve causality identification in the financial domain through textual data. This shared task focuses on determining causality associated with both events and quantified facts. In this task, a cause can be the justification of a statement or the reason explaining an o... |

Rodríguez Cabello, Daniel, 2025, "Dataset on the Impact of Programming Platforms with Simulated Robotics on Computational Thinking and Gender Analysis in Secondary Education", https://doi.org/10.21950/BYBWIX, e-cienciaDatos, V1
This dataset was collected during a quasi-experimental study involving 161 secondary school students (aged 14) from Madrid, Spain. The objective was to evaluate the impact of three programming environments—Scratch (2D), Scratch with Kibotics (3D robotics simulation), and Python with Kibotics—on the development of Computational Thinking (CT) skills.... |
Jul 17, 2025 - Green hydrogen production from waste biomass pyrolysis fractions by auto-thermal reforming in a membrane reactor BIOWASTETOH2
MEGIA, Pedro J.; Soria, Miguel Angel; Pereira Cerqueira, Pedro; Vizcaíno, Arturo; CARRERO, ALICIA; Calles, Jose A; Madeira, Luis Miguel, 2025, "Influence of Rh addition to transition metal-based catalysts in the oxidative steam reforming of acetic acid", https://doi.org/10.21950/ESGLOA, e-cienciaDatos, V1
In this work, the Rh-promotion to transition metal (Ni and Co) CeO2-supported catalysts has been studied for the first time on the acetic acid oxidative steam reforming. Characterization of the prepared catalysts confirmed the promoting effect of rhodium addition, allowing lower crystallite size which increases the number of available active sites... |

MEGIA, Pedro J.; Morales Cabezas, Anabel; Vizcaíno, Arturo; Calles, Jose A; CARRERO, ALICIA, 2025, "Hydrogen production through oxidative steam reforming of acetic acid over Ni catalysts supported on Ceria-based materials", https://doi.org/10.21950/DRN2GT, e-cienciaDatos, V1
Oxidative steam reforming allows higher energy efficiency and lowers coke deposition compared to traditional steam reforming. In this work, CeO2-based supports have been prepared with Ni as the active phase, and they were tested in the oxidative steam reforming of acetic acid. The in-fluence of the O2/AcOH molar ratio (0 - 0.3) has been evaluated o... |

MEGIA, Pedro J.; Morales Cabezas, Anabel; Vizcaíno, Arturo; Calles, Jose A; CARRERO, ALICIA, 2025, "Oxidative steam reforming of acetic acid on Ni catalysts: Influence of the La promotion on mesostructured supports", https://doi.org/10.21950/SGPWTE, e-cienciaDatos, V1
In this work, the support effect and the La2O3 promotion of Ni-based catalysts on the oxidative steam reforming of acetic acid as bio-oil model compound has been studied. Ni/SBA-15 showed the worst catalytic performance with an acetic acid conversion dropping below 30% at 500 ºC ascribed to active phase oxidation. In contrast, Ni supported over mes... |

MORENO DE LA CALLE, Alvaro; Vizcaíno, Arturo; CARRERO, ALICIA; Calles, Jose A; MEGIA, Pedro J., 2025, "Study of Mesostructured CeO2 Synthesis via Nanocasting Using SBA-15 as a Template: Influence of the Cerium Precursor", https://doi.org/10.21950/O8CMEE, e-cienciaDatos, V1
Mesoporous materials with high surface area, large pore volume, and adjustable pore size are promising in the fields of adsorption and heterogeneous catalysis. In this work, ordered meso-porous ceria structures were successfully prepared via nanocasting using SBA-15 as a template with Ce(NO3)3·6H2O or CeCl3·7H2O as ceria precursors. The materials w... |

MEGIA, Pedro J.; Lourdes García-Moreno; Vizcaíno, Arturo; Calles, Jose A; CARRERO, ALICIA, 2025, "Bioethanol steam reforming for hydrogen production over Ni‑Cr/SBA 15: Influence of metal loading and Ni/Cr ratio", https://doi.org/10.21950/RPTIHB, e-cienciaDatos, V1
This work examines the influence of metal loading and Ni/Cr ratio of Ni-Cr/SBA-15 catalysts on bioethanol steam reforming for the first time. The characterization of the synthesized samples reveals that higher Cr amounts results in lower Ni crystallite sizes due to the promoting effect of Cr, thereby enhancing the dispersion of the active phase. Th... |

This work explores the effect of CeO2 incorporation into Co/SBA-15 catalysts on hy-drogen production through acetic acid oxidative steam reforming as a bio-oil aqueous phase model compound. CeO2 was incorporated (5–30 wt.%) to improve the physico-chemical properties of the catalyst. XRD analysis confirmed that CeO2 addition resulted in smaller Co0... |
