This dataset contains the experimental data generated during the evaluation of different materials as potential barriers against radon released from phosphogypsum. It includes the raw radon concentration measurements recorded in the source and receiver chambers during 148.5-hour tests, the main specifications of the experimental set-up used to perform the measurements, and the thickness measurements of the tested materials. The experimental data were used to determine the radon concentration reduction achieved by each material, as reported in the associated conference proceedings paper. The experimental data were generated using a two-chamber experimental set-up designed in accordance with ISO/TS 11665-13:2017 to evaluate the effectiveness of different materials as barriers against radon released from phosphogypsum. It consisted of two sealed AISI 316L stainless steel chambers (2 mm thickness, 0.801 L volume and 78.5 cm² test area) separated by the test sample. Phosphogypsum with an activity of 2.29 Bq was placed inside the source chamber, while the receiver chamber collected the radon that permeated through the sample. Radon concentration in both chambers was continuously monitored using two Durridge RAD7 detectors. Ten different materials were evaluated. Each test lasted 148.5 hours, during which radon concentrations in the source and receiver chambers were recorded at 1.5 hour intervals. These raw experimental data were used to determine the percentage reduction in radon concentration achieved by each material. The radon concentration data recorded by the RAD7 detectors at 1.5 hour intervals were exported. For each experiment, the dataset includes the test date and the radon concentration values measured in the source and receiver chambers throughout the 148.5 hour test. No additional processing was applied to the concentration data. The experimental set-up specifications were compiled. For the thickness data, the reported mean thickness and standard deviation were calculated from eight thickness measurements taken at different locations on each material. The dataset also includes the main specifications of the experimental set-up, such as chamber characteristics, phosphogypsum activity and test area. The thickness of each material was determined from eight measurements taken at different locations, from which the mean thickness and the standard deviation were calculated.

Nowadays, there is a severe problem with waste generation, especially with single-use packaging. Although the trend is to try to recycle or reuse this waste, a significant amount still ends up in landfills, which represents a serious environmental problem. This waste includes laminated materials, which are difficult to recycle because the polymeric material and aluminium layers cannot be separated easily. This work proposes the study of the valorisation of several laminated wastes as radon barriers for indoor spaces due to the similarity in composition between these waste and commercial radon barriers. This dataset contains the experimental data generated during the evaluation of laminated wastes composed of polymeric and aluminium materials as potential radon barriers for indoor spaces. It includes the raw radon concentration measurements recorded in the source and receiver chambers during 48-hour diffusion tests, the main specifications of the experimental set-up used to perform the measurements, and the thickness of the laminated waste samples used in the study. The experimental data were used to calculate the radon concentration reduction and the radon diffusion coefficient, following a modified version of the ISO/TS 11665–13:2017 standard, as reported in the associated publication.

Fishmeal substitution effects on the growth and microbiome of Chelon labrosus [Dataset]
(Universitat Politècnica de València, 2026-07-14) Querol Edo, Mariola; Peñaranda, D.S.; Martín Montero, Ignacio; Sanz Latorre, Markel; Egea Nicolás, María de los Ángeles; Tomas-Vidal, A.; Martínez-Llorens, Silvia; Aguado Giménez, Felipe; Departamento de Ciencia Animal; Instituto Universitario de Ciencia y Tecnología Animal; Escuela Técnica Superior de Ingeniería Agronómica y del Medio Natural; Ministerio de Ciencia e Innovación; Gobierno de Cantabria
As aquaculture expands, replacing fishmeal with alternative proteins in low-trophic species such as Chelon labrosus is critical for sustainability. We evaluated growth performance over 153 days and nutrient digestibility of three isoproteic diets: a fully plant-based diet (V), a plant–animal blend without fishmeal (VA), and a control with 20% fishmeal (FM). Fish fed the V diet achieved the highest growth and feed efficiency, followed by FM, whereas VA resulted in poor performance and the lowest digestibility, likely linked to hemoglobin meal reducing feed acceptability. All diets significantly shifted intestinal microbial diversity from initial conditions, while dominant taxa remained largely stable. FM-fed fish showed a general decrease in bacterial abundance, including a marked reduction of Brevinema. The VA diet increased Vibrio and decreased Lactobacillus, suggesting compromised gut health. In contrast, V-fed fish displayed elevated Mycoplasma, a taxon previously associated with nutrient exchange and fiber digestion. Functional predictions indicated fewer metabolic alterations under plant-based diets, while FM induced the largest number of altered pathways. Overall, complete fishmeal replacement is feasible in C. labrosus, and diet–microbiome interactions are pivotal to optimizing sustainable mullet aquaculture.

This article introduces a nationwide dataset that maps how 104,553 Spanish firms communicate and implement energy transition practices on their corporate websites in 2023 and 2025. Using a scalable pipeline based on large language models (LLMs), website text is segmented, semantically filtered, and evaluated through a structured rubric designed to identify explicit evidence of: (1) energy efficiency and energy consumption reduction actions, (2) decarbonization and greenhouse gas emissions reduction strategies, and (3) the use, production, or procurement of renewable energy. The resulting indicators are aggregated at the province (NUTS-3), sector (NACE 2-digit), and firm-size level, providing a detailed picture of corporate energy transition patterns across the Spanish economy. To preserve anonymity and statistical robustness, only aggregated cells containing at least four firms with valid website content are included in the public dataset. For each province–sector–size combination, the dataset reports the share of firms associated with each transition dimension together with the number of firms represented in the cell. By covering two years, the dataset enables the analysis of temporal changes in corporate sustainability and energy transition strategies across regions, industries, and firm-size categories. The dataset provides a reproducible and extensible framework for studying energy transition dynamics using web-based evidence and LLM-assisted classification, offering valuable applications for sustainability research, regional analysis, industrial transformation studies, and energy policy evaluation.

Multivariate dataset of cocoa roasting progression, bioactive compounds and neoformed contaminants during thermal processing [Dataset]
(Universitat Politècnica de València, 2026-05-04) Girón Hernández, Lunier Joel; Barrios-Rodríguez, Yeison Fernando; Medina Orjuela, María; Gómez, Danilo; Jiménez Ochoa, Jessica P.; Amorocho Cruz, Claudia Milena; Carranza, Carlos; Departamento de Tecnología de Alimentos; Escuela Técnica Superior de Ingeniería Agronómica y del Medio Natural; Centro de Biomateriales e Ingeniería Tisular
Cocoa roasting triggers coupled thermal reactions that shape bioactive composition and promote neoformed contaminants (NFCs), but frameworks linking precursor dynamics and bioactivity remain limited. Here, multivariate relationships among Maillard precursors, physicochemical variables, bioactive descriptors and NFCs were evaluated during cocoa roasting at 110–130º C across six roast progression (RP) stages. RP was the main driver of chemical change: sucrose decreased by >95%, while glucose and fructose peaked at RP1-RP2 (up to ~2500 mg/ g) before declining, alongside a decrease in asparagine to ~0.1–0.2 mg/g. NFCs peaked at intermediate stages and then decreased with advanced roasting (40–95%), as did phenols, antioxidant activity (60–85%) and methylxanthines (~90%). Pareto-PCA revealed a safety-bioactivity trade-off, identifying RP3-RP4 as relevant window. Partial Least Squares Regression showed that furfuryl alcohol (R (R 2 2 2 =0.83) and 5-hydroxymethylfurfural = 0.82) were well explained by information on precursors, physicochemical properties and bioactive compounds, while acrylamide (R = 0.34) remained poorly predictable.

(Universitat Politècnica de València, 2026-05-20) Olivares Perona, Ruben; Tomas-Vidal, A.; Brol, Jessica; Jauralde García, Ignacio; Jover Cerda, Miguel; Peñaranda, D.S.; Martínez-Llorens, Silvia; Instituto Universitario de Ciencia y Tecnología Animal; Departamento de Ciencia Animal; Escuela Técnica Superior de Ingeniería Agronómica y del Medio Natural; Escuela Politécnica Superior de Gandia; Ministerio de Ciencia e Innovación; Universitat Politècnica de València; Generalitat Valenciana
[EN]Considering the increasing demand for sustainable aquafeeds, the present study aimed to evaluate the potential of dietary fishmeal inclusion in diets for Liza aurata with alternative protein sources of animal, plant, and unicellular origin. Four experimental diets were formulated with varying levels of fishmeal inclusion (FM15, FM10, FM5, and FM0, representing 15%, 10%, 5%, and 0% fishmeal, respectively) to assess their effects on growth performance, body composition, and economic viability in juvenile Liza aurata (9.14 ± 1.52 g). After three months, there were no significant differences in the survival rates or growth parameters among diets. Nonetheless, fish fed diet without fishmeal showed the lowest condition factor and mesenteric fat. The results on body composition indicated similarities among treatments in terms of amino acid and fatty acid profiles. Fish fed the diet without fishmeal obtained the lowest values of the Fish in–Fish out ratio for fishmeal (FIFO FM), the Marine protein dependency ratio (MPDR), and the Marine oil dependency ratio (MODR). Finally, polynomial regressions demonstrated a negative trend in some indices as fishmeal content was reduced. In conclusion, the findings suggest that while Liza aurata can be reared on low level of dietary fishmeal, but a minimum inclusion level of 9% fishmeal is needed to maintain optimal growth, filet quality, and the economic profitability.

Ethical slaughter practices for crustaceans remain poorly standardized, and their effects on product quality and consumer perception are insufficiently understood. This study evaluated four ice-slurry-based slaughter methods in Penaeus vannamei reared under intensive biofloc technology (BFT) and their impact on refrigerated shelf life. While BFT enhances farming sustainability, it may an increase in microbial load, potentially shaping post-mortem spoilage. Shrimp were subjected to cold thermal shock in seawater ice slurry (C-TS); a 5 min immersion in chilled seawater with 50 ppm sodium hypochlorite, followed by TS (5BTS); 3–4 h of intestinal clarification, followed by 1 min immersion in chilled seawater with 50 ppm sodium hypochlorite and subsequent TS (C1BTS); and TS, followed by UV-C exposure (TS-UV). Over 12 days at <4 ◦C refrigeration, culture-based microbiology (mesophilic bacteria, enterobacteria, psychrotrophs, pseudomonas, and specific spoilage organisms), total volatile nitrogen compounds (TVB-N), melanosis, and qualitative descriptive analysis were performed. Storage time showed typical spoilage patterns driven by psychrotrophic bacteria, TVB-N, and melanosis. Slaughter method influenced quality: C1BTS limited psychrotroph proliferation but accelerated melanosis, and TS-UV yielded the poorest performance. Notably, 5BTS delayed melanosis (~3 days), maintained sensory quality, and avoided excessive microbial growth, making it the most effective method. These findings provide practical guidance for additive-free shrimp processing and identify psychrotrophs as key spoilage indicators in BFT systems.

This study reports the bio-mediated synthesis of tungsten trioxide nanostructures from aqueous extracts of Melia azedarach (L.) dry leaves. The synthesis was carried out by electrochemical anodization of tungsten foils in the presence of different volume percentages of leaves extracts. These nanostructures were afterwards characterized by X-Ray Diffraction (XRD), impedance measurements and linear sweep voltammetry in the presence of simulated solar light. Finally, these nanoelectrodes were used as (photo)electrocatalysts in the photoelectrochemical water splitting process to obtain green hydrogen and as anodes in Li-ion rechargeable batteries. Description of methods used for collection/generation of data: - Synthesis of WO3 nanostructures: The leaves of M. azedarach were randomly sampled from several mature trees from the surroundings of the Burjassot Campus of the University of Valencia (Spain). Fresh leaves were rinsed with tap and distilled water and subsequently air-dried indoors for 1 week, at room temperature. The extracts were obtained from dried leaves, by mixing 15 g of material with 150 mL of distilled water at 60 ºC. The infusion was maintained at that temperature for 20 min. After that, the solution, once cooled, was filtered through filter paper and used to prepare the different reaction media. Nanostructures of WO3 were synthesized by subjecting tungsten foils (1,3 cm2 of exposed area) to an anodization process with a cell potential of 20 V, for 4 h. A platinum foil served as the cathode within the cell. The anodization process employed an aqueous electrolyte composed of 1.5 M methanesulfonic acid (MSA) with varying proportions of M. azedarach leaves extract (from 0% to 10%, in volume), at a temperature of 50◦C. Anodization was performed under controlled hydrodynamic conditions, by means of a Rotating Disk Electrode (RDE) set a constant rotation speed of 750 rpm. Following anodization, a thermal treatment (annealing) was carried out in a tubular oven at 600◦C for 4 h in an air atmosphere to obtain crystalline WO3 nanostructures. - Morphological and structural characterization: X-Ray diffraction analyses (XRD) were performed to investigate the crystallinity of the WO3 samples. A D8AVANCE diffractometer (Bruker) equipped with a monochromatic Cu Kα1 source was used. -(Photo)electrochemical characterization: impedance measurements and photocurrent density vs potential curves: Electrochemical characterization of the WO3 nanostructures was conducted through impedance measurements, performing Electrochemical Impedance Spectroscopy (EIS) and Mott-Schottky (MS) analyses. All electrochemical tests were carried out using a three-electrode cell with the nanostructures acting as working electrodes, a silver/silver chloride (3 M KCl) electrode was the reference electrode and a platinum tip served as counterelectrode. Measurements were performed with a PalmSens4 potentiostat and 0.1 M H2SO4 was used as electrolyte. The sample area exposed to that electrolyte was 0.5 cm2. For EIS, a constant potential of 1 V was selected with an amplitude of 10 mV, scanning the frequency from 100 kHz to 10 mHz. For MS analysis, a constant frequency of 5 kHz was used, while the potential was scanned from 1 V to 0.2 V at a rate of 50 mV/s. For the photoelectrochemical characterization of the WO3 nanostructures, the same experimental set-up was used, with the addition of a solar simulator with AM 1.5 conditions (100 mW/cm2). Linear voltammetries to obtain photocurrent density – potential curves were conducted from 0.2 V to 1.05 V, by applying dark-light pulses (16 s in the dark followed by 4 s with illumination) while the potential was scanned. - Evaluation of WO3 nanostructures as Li-ion battery anodes: WO3 nanostructures were evaluated as anodes (negative electrodes) for Li-ion batteries. For that purpose, Swagelok-type cells were used, with WO3 nanostructures acting as working electrodes and a metallic lithium foil acting as both the counter and the reference electrodes. Batteries were assembled inside an Ar-filled glove box, using 1 M LiPF6 in ethylene carbonate/dimethyl carbonate/diethyl carbonate 1:1:1 (v/ v/v) as electrolyte (Sigma-Aldrich) and a Whatman glass microfiber separator. After sealing the cells, they were cycled outside the glove box at room temperature, using a Biologic BCS-815 cyclic station. Galvanostatic charge/discharge curves were recorded at different cycling rates (from C/10–1 C, and returning to C/10) within a potential window between 1 V and 3.5 V vs Li/Li+.

Biofloc technology transforms nitrogen wastes into microbial biomass, that can be consumed in situ by cultured animals. The process requires addition of an exogenous carbon source at a specific carbon-to-nitrogen (C:N) ratio. In this study, three carbon sources at 10:1, 18:1, and 26:1 C:N ratios were tested under super-intensive conditions (350 P.vannamei/m³): molasses (MOL, control), yeast (YST), with an initial brewer's yeast addition and polybutylene succinate (PBS, as slow-release carbon source). Through biofloc maturation, the water quality parameters remained optimal, with PBS strategy and low-to-intermediate C:N ratios exhibiting reduced nitrogen and phosphate levels. The mineral dynamics evidenced that seawater and biofloc experienced a decrease in Ca, K, Mg, and Sr while shrimp accumulated these elements over time. Additionally, the biofloc acted as a mineral reservoir accumulating several times more ions than water and shrimp. Carbon strategies influenced bacterial composition of biofloc differently, with YST treatment supporting dominant bacterial groups, while PBS favored less abundant taxa. Both MOL and YST promoted an increase in heterotrophic bacteria, however, MOL exhibited a more balanced distribution of key bacterial groups involved in the nitrogen cycle. Regarding shrimp performance, PBS produced the lowest specific growth rate despite showing better water quality and higher bacterial diversity, likely due to reduced heterotrophic bacteria. Finally, a principal component analysis highlighted the interactions between water quality, bacterial diversity and shrimp growth. Overall, the findings suggest that MOL carbon addition strategy at low-to-intermediate C:N ratios as the most recommendable based on its more balanced bacterial composition and good shrimp performance.
