title: Dataset on the Impact of Programming Platforms with Simulated Robotics on Computational Thinking and Gender Analysis in Secondary Education

description: 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. The data includes pre-test and post-test scores based on a validated CT assessment instrument, as well as programming exam scores and item-level data related to CT subskills (loops, conditionals, functions, etc.). Gender, platform, and programming language are also included as independent variables for analysis. The study also explores the effect of these tools on reducing gender gaps in CT education.

The dataset is anonymized and includes both raw scores and normalized results (0–10 scale). It can be used to reproduce the statistical analysis of the study, to conduct further research in STEM education, or to test machine learning models for educational data mining.

title: The Financial Document Causality Detection Shared Task (FinCausal 2025): Dataset

description: &lt;p&gt;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 outcome. Therefore, it is a relation detection task.
The main difference compared to the 2023 edition is that the task is framed as a Question Answering (QA) problem. The question is posed in an abstractive manner, while the predicted answer must be extractive. Additionally, the Semantic Answer Similarity (SAS) metric has been introduced.&lt;/p&gt;
&lt;p&gt;Participants, given the context and the abstractive question, must extract the literal answer from the context that responds to that question. The questions seek causal-type relationships, either causes or effects.&lt;/p&gt;
&lt;p&gt;The task dataset has been extracted from a corpus of Spanish financial annual reports from 2014 to 2018. Participants are provided with a CSV file containing the following fields: ID; Text; Question; Answer.&lt;/p&gt;
&lt;p&gt;The standard way to participate is to fine-tune a model using the data annotated by linguists (including Inter-Annotator Agreement, IAA), and then use the fine-tuned model to predict the "ANSWER" field in the test set.&lt;/p&gt;
&lt;p&gt;This publication refers to the dataset used in the competition.&lt;/p&gt;
&lt;p&gt;This is a dataset from the FinCausal 2025 competition. It is designed for participants to use it to fine-tune their models and complete the task with the highest possible similarity to the gold standard, according to the established metrics.&lt;/p&gt;
&lt;p&gt;It consists of texts annotated by linguists, where a context, an abstractive question, and its corresponding extractive answer—which addresses the causal nature of the question—are provided.&lt;/p&gt;
&lt;p&gt;There are two versions available: one in English and one in Spanish.&lt;/p&gt;

title: Hydrogen production through oxidative steam reforming of acetic acid over Ni catalysts supported on Ceria-based materials

description: 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 over Ni/CeO2. The results stated that by increasing oxygen content in the feeding mixture, acetic acid conversion increases, too with a decrease in coke deposition, and hydrogen yield. To have a proper balance between the acetic acid conversion and the hydrogen yield an O2/AcOH molar ratio of 0.075 was selected to study the catalytic performance of Ni catalysts over different supports: commercial CeO2, a novel mesostructured CeO2, and CeO2-SBA-15. Due to higher Ni dispersion over the support, the mesostructured catalysts allowed higher acetic acid conversion and hydrogen yield compared to the non-porous Ni/CeO2. The best catalytic performance and the lowest coke formation (120.6 mgcoke·gcat 1·h 1), were obtained with the mesostructured Ni/CeO2. This sample reached almost complete conversion (&gt; 97%) at 500 °C, maintaining the hydrogen yield over 51.5% after 5 h TOS, being close to the predicted value by the thermodynamic equilibrium due to the synergistic co-ordination between Ni and CeO2 particles.

title: Influence of Rh addition to transition metal-based catalysts in the oxidative steam reforming of acetic acid

description: 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 to reactants, along with higher reducibility as evidenced by temperature-programmed reduction (H2-TPR). The influence of the reaction temperature on the acetic acid conversion and hydrogen yield was assessed. Co-based catalysts achieved better catalytic performance than Ni-based samples, almost complete acetic acid conversion, and hydrogen yields were close to the equilibrium values at temperatures over 500 ºC. On the other hand, tests at higher weight-hour space velocity evidenced the superior activity of Co-Rh/CeO2 sample. This sample showed good stability with almost complete acetic acid conversion after 25 h time-on-stream, decreasing only the hydrogen yield by 7% after the first 8 h along with a slight increase in the acetone yield of about 6%. This suggests that after the acetic acid ketonization, acetone steam reforming advanced to a lesser extent on the reaction mechanism because of long-term slight catalyst deactivation.

title: Oxidative steam reforming of acetic acid on Ni catalysts: Influence of the La promotion on mesostructured supports

description: 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 mesoporous CeO2 (CeO2-m) reached better catalytic performance and lower coke formation due to the higher Ni dispersion and oxygen mobility of the support. On the other hand, La2O3 promotion to SBA-15 and CeO2-m led to even higher Ni dispersion and prevented sintering during the reforming reaction. This effect resulted in an improvement in the catalytic performance for both promoted samples. As a consequence of low Ni crystallite size and high oxygen mobility, Ni/La2O3-CeO2-m reached almost complete conversion (~ 96%), the highest hydrogen yield (~ 53%) maintained for 5 h with the lowest coke formation (62.3 mgcoke·gcat 1·h 1).

title: Study of Mesostructured CeO2 Synthesis via Nanocasting Using SBA-15 as a Template: Influence of the Cerium Precursor

description: 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 were characterized before and after template removal. CeO2 crystallite size in the CeO2/SBA-15 composites increases with successive impregnations until they reach the pore size of the SBA 15. Upon removal of the SBA-15 template, the synthesized materials exhibit pore diameters corresponding to the wall thickness of the SBA-15, evidencing that the inverted structure is obtained. Mesoporous ceria exhibits in-creasingly ordered structure up to 5 successive impregnations with 1.3 mmolCe/gSBA-15. Using ce-rium chloride as a precursor, highly ordered structures are reached after only 3 impregnations. The feasibility of this synthesis in fewer steps (1, 3, and 5) employing the same amount of Ce precursor (6.7 mmolCe/gSBA-15) was also studied. Results show a higher ordering degree and oxygen mobility capacity at higher impregnation steps. The mesostructured ceria samples exhibit significantly higher oxygen mobility than commercial bulk ceria, along with high thermal stability, which high-lights the usefulness of these structures.

title: Exploring CeO2-doped Co/SBA-15 catalysts for acetic acid oxi-dative steam reforming

description: 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 mean crystallite sizes, while H2-TPR showed enhanced reducibility properties. The catalytic performance was evaluated in the 400–700°C range, S/C molar ratio = 2, O2/C molar ratio = 0.0375, WHSV = 30.2 h-1, and P = 1 atm. Catalysts containing 10 and 20 wt.% of CeO2 exhibited the best catalytic performance, achieving nearly complete conversions and H2 yield values approaching thermodynamic equilibrium at 550 °C. Both samples maintained an acetic acid conversion above 90% after 30 h of time-on-stream with H2 yields above 55 % along the steam reforming tests. This agrees with their lower coke formation rate (7.2 and 12.0 mgcoke·gcat-1·h-1 for Co/10CeO2-SBA15 and Co/20CeO2-SBA15, respectively).

title: A thermodynamic comparison between conventional, autothermal, and sorption-enhanced bio-oil steam reforming

description: This study presents a comprehensive thermodynamic analysis comparing three bio-oil steam reforming processes: traditional steam reforming, autothermal reforming, and sorption-enhanced steam reforming. Using Aspen Plus V12.1 software, simulations were performed to evaluate the hydrogen production, energy requirements, and the influence of key process variables such as temperature, pressure, or steam-to-carbon ratio. While traditional steam reforming is capable of achieving high hydrogen production, it requires substantial external energy input to drive forward the reaction given the endothermic nature of the reactions. In comparison, autothermal reforming allows thermal neutral conditions by integrating endothermic steam reforming with exothermic partial oxidation reactions. Although the energy requirements significantly decrease, it also leads to lower hydrogen yields due to its consumption in the oxidation processes. In contrast, sorption-enhanced steam reforming improves hydrogen production compared to the other configurations ascribed to the in-situ CO2 capture by using sorbents that shift the equilibrium towards hydrogen with purities over 98%, thus minimizing the need for additional gas separation processes apart from reducing the CO and CH4 formation. Additionally, the exothermic nature of CO2 capture reactions contributes to reducing the energy requirements or even generates excess energy at certain conditions that can be used as a heat source. The bio-oil composition, showed minor variations in hydrogen yields, making these findings applicable to different bio-oil compositions.

title: Continous flowing eletroless pore plating to fabricate H2 selective Pd-Membranes

description: This study presents a novel approach to fabricating hydrogen-selective palladium membranes by continuous flowing electroless pore-plating, hereafter referred to as cf-ELP-PP. This procedure aims to significantly advance the manufacturing processes of dense membranes. In fact, the transition from traditional batch to continuous methods enhances production efficiency and membrane quality, thus being possible to reach improved hydrogen permeation capabilities. Particularly, these novel membranes exhibited a H2-permeance ranging between 3.29·10⁻⁴ and 4.77·10⁻⁴ mol m-2 s-1 Pa-0.5 with H₂/N₂ ideal separation factor greater than 10,000 for the entire set of experiments. This research also addresses key challenges related to the stability and efficiency of membranes, providing relevant insights for their operation during prolonged times even if unfavorable operating conditions are adopted. All these findings underscore the potential of cf-ELP-PP membranes for effective hydrogen purification in a wide variety of future industrial applications, aligning with the increasing demand for sustainable energy solutions. Moreover, the work also paves future enhancements in hydrogen production and separation processes by providing valuable insights for researchers in fields of materials science, chemical engineering, and renewable energy technologies
