(Universitat Politècnica de València, 2026-06-01) Martínez-Barbero, Xavier; Pastor-Merino, Ana; Domenech, Josep; Facultad de Administración y Dirección de Empresas; Departamento de Economía y Ciencias Sociales; Grupo de Investigación de Economía Internacional y Desarrollo; Generalitat Valenciana; Agencia Estatal de Investigación; Ministerio de Ciencia e Innovación
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.

(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.

Slaughter Method Effects on Quality and Shelf Life in Biofloc Shrimp [Dataset]
(Universitat Politècnica de València, 2026-05-14) Ferrando-Juan, Sara; Honrado Frías, Adrián; Tomas-Vidal, A.; Martínez-Llorens, Silvia; Rodilla, M; Jover Cerda, Miguel; Beltrán García, Javier; Peñaranda, D.S.; Calanche Morales, Juan; Instituto Universitario de Ciencia y Tecnología Animal; Departamento de Ingeniería Hidráulica y Medio Ambiente; Departamento de Ciencia Animal; Escuela Politécnica Superior de Gandia; Instituto de Investigación para la Gestión Integrada de Zonas Costeras; Escuela Técnica Superior de Ingeniería Agronómica y del Medio Natural; Agencia Estatal de Investigación; Universitat Politècnica de València; Gobierno de Aragón
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.

Synthesis of anodized WO3 nanocatalysts using Melia azedarach leaves extract for energetic applications [Dataset]
(Universitat Politècnica de València, 2026-04-20) Fernández Domene, Ramón Manuel; Solsona Espriu, Benjamin Eduardo; Erans Moreno, María; Blasco-Tamarit, E.; Sánchez Tovar, Rita; Departamento de Ingeniería Química y Nuclear; Escuela Técnica Superior de Ingeniería Industrial; Instituto Universitario de Seguridad Industrial, Radiofísica y Medioambiental; Agencia Estatal de Investigación; Generalitat Valenciana
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.

(Universitat Politècnica de València, 2026-03-13) Cascales Martos, Tatiana
Biofloc systems improve water quality and add nutritional value to aquaculture production through complex microbial and planktonic communities, in which the inclusion of microalgae can enhance nutrient recycling and overall system functionality. This study evaluated the inoculation of microalgae in biofloc systems for Penaeus vannamei under different photoperiod regimes. In the first experiment, Chlorella sp. under 16:8 and, particularly, 12:12 photoperiods established stable populations, increased biofloc biodiversity, and improved the mineral profile of the system. In the second experiment, Chlorella sp. persisted for up to 32 days following a single inoculation, reduced nitrate accumulation, and enriched the biofloc with polyunsaturated fatty acids associated with immune function. Although no consistent effect on animal growth was observed, the results highlight the interaction between water quality, biofloc composition, and zootechnical performance. Overall, Chlorella sp. under a 12:12 photoperiod enhanced the ecological and nutritional quality of the biofloc, although further studies are required to optimize inoculation protocols and maximize productive benefits.

[EN] The production of Penaeus vannamei faces multiple challenges, from environmental constraints and disease outbreaks to the need for sustainable and improved farming practices, essential for responsible production. Biofloc technology offers a sustainable approach by enhancing water quality and serving as a complementary nutritional source. However, protein requirements in biofloc-based shrimp culture systems remain insufficiently defined despite their economic relevance. This study aimed to optimize dietary protein levels and feeding regimes for P. vannamei cultured under biofloc technology, while assessing the nutritional contribution of bioflocs through stable isotope analysis. A two-phase factorial experiment was conducted. In the juvenile stage, five diets containing 30–46% crude protein (CP) were tested under three feeding regimes (70, 85, and 100% of average daily ration). Shrimp fed 38% CP at 70% feeding achieved growth comparable to higher CP and feeding levels, indicating this combination as optimal for juveniles. In the grow-out phase, shrimp were fed 34–42% CP diets at a fixed 70% feeding rate. Growth performance, nutrient composition, and isotopic signatures (δ¹³C and δ¹⁵N) were evaluated to estimate carbon and nitrogen assimilation from feed and biofloc sources. Growth was maintained even at 34% CP, suggesting lower protein requirements for larger shrimp. Stable isotope analysis confirmed that biofloc contributed significantly to nitrogen and carbon assimilation, especially under reduced dietary protein. Results also demonstrate that a permanent 70% feeding strategy sustained shrimp performance under biofloc conditions. This outcome underscores the role of biofloc as a nutritional supplement, contributing to a more sustainable and cost-effective shrimp farming.

Ti-felt anodes, with high surface area, have been used as supports of Pt and SnO2-Sb-Pt electrocatalysts. Anodes have been applied in a filter-press electrochemical reactor for the electrooxidation of polystyrene nanoplastics (NPs) (100 mg·L-1). Two types of configurations have been used. In the first, the solution with NPs flows through the anode, taking advantage of its porosity (acting as a sort of membrane) to enhance the contact of NPs with the anode and the oxidative species generated. In the second configuration, the solution of NPs flows parallel to the anode, and the NPs flow parallel to it. Comparing both configurations at 25 mA·cm-2, for the Ti-Pt anode, the flow-through configuration decreases energy consumption by ~7-fold and treatment time by ~15-fold when compared to the flow-by configuration. For Ti-SnO2-Sb-Pt anode, ratios of ~6.5-fold and ~13-fold were obtained, respectively. Moreover, the effect of the current density (50, 25, 12.5, and 5 mA·cm-2) was studied. For the Ti-Pt electrode, a treatment time of only 40 minutes was achieved at a current density of 25 mA·cm-2 with the F-T configuration, with a faradaic efficiency of 62.09 %, and electrochemical energy per order (EEO) of 21.91 kW·h·m-3·order-1. In the case of the F-B configuration at 25 mA·cm-2 the treatment time increases until 600 min, with a faradaic efficiency of 8.27 % and EEO of 156.57 kW·h·m- 3·order-1.

The influence of three annealing atmospheres (air, nitrogen and argon) and the use of controlled hydrodynamic conditions (from 0 to 5000 rpm) on morphological, structural, chemical and photoelectrochemical properties of TiO2 nanotubes have been evaluated. For this purpose, different characterization techniques have been used: Raman Confocal Laser Spectroscopy, X-Ray Photoelectron Spectroscopy, Mott-Schottky analysis and photoelectrochemical water splitting tests. According to the results, it can be concluded that both hydrodynamic conditions and annealing in non-oxidizing atmospheres improve the photoelectrochemical response of the TiO2 nanotubes. This fact has been attributed to the oxygen vacancies formed after annealing in argon and nitrogen atmospheres and also to the presence of nitrogen into the TiO2 lattice due to the thermal treatment in the nitrogen atmosphere.

Remote power systems require the operation of local generation resources, energy storage systems and loads in a harsh environment in which either there is no connection to the public electric grid (off-grid systems) or the grid is extremely weak and full of abnormalities. The general goal of this project is to improve the characteristics of remote power systems by means of power electronics converters. The data are organized in 9 main folders, each folder corresponding to a publication derived from the REMOTEWEAK project. The publications are journal papers or papers published in proceedings of international conferences

(Universitat Politècnica de València, 2026-02-03) Torán, Enric; Liberos, Marian; Patrao Herrero, Iván; González-Medina, Raúl; Garcerá, Gabriel; Figueres Amorós, Emilio; Departamento de Ingeniería Electrónica; Escuela Técnica Superior de Ingeniería Aeroespacial y Diseño Industrial; Grupo de Sistemas Electrónicos Industriales; Escuela Técnica Superior de Ingeniería Industrial; Ministerio de Ciencia e Innovación; European Regional Development Fund
A theoretical analysis of a three-phase grid-connected B4 photovoltaic inverter was carried out, including modeling, control design, and stability assessment of the current and voltage control loops. The influence of photovoltaic voltage and grid inductance variations was analyzed through a parametric stability study. Finally, simulation-based evaluations were performed under ideal and distorted grid conditions to assess harmonic behavior, DC bus voltage ripple, and overall system performance.
