The increasing demand and limited availability of fishmeal (FM) have intensified the need for sustainable alternative protein sources in shrimp aquafeeds. This study evalu-ated high FM replacement in juvenile Penaeus vannamei reared under biofloc technology (BFT), integrating in vitro protein digestibility, growth performance, nutrient utilization and microbiome analyses. Six isoproteic and isolipidic diets combined two FM levels (0% and 7.5%) with animal (A), plant (P), or mixed (AP) protein sources, plus a 15% FM control diet were assayed. Plant based diets showed higher in vitro protein digestibility and amino acid release than animal based diets. However, these differences were not reflected in shrimp growth, as final body weight, SGR and survival were similar among dietary treatments. Apparent feed conversion ratio, protein efficiency, and economic performance were improved in shrimp fed the A7.5 and AP7.5 diets, whereas complete FM replacement resulted in poorer performance. Biofloc and shrimp intestinal microbial community composition was primarily driven by temporal succession, whereas dietary protein source modulated the abundance of specific bacterial families. Biofloc and in-testinal communities shared limited taxonomic overlap at the family level, suggesting restricted microbial exchange together with strong habitat and host mediated selection. Overall, these findings indicate that a diet containing 7.5% fishmeal (FM), supplemented with either animal derived proteins or a combination of animal and plant derived pro-tein sources, represents an optimal strategy for juvenile Penaeus vannamei cultured under BFT conditions, maintaining growth performance while preserving intestinal microbial stability and health., This work was supported by the I+D+i Research Project “Optimizing Shrimp Feeding and Nutrition in Biofloc Systems (BioFlango)” (PID2020-114574RB-C21) and by a predoctoral Research Personnel Training Grant awarded to S.

The early intestinal response of Mugil cephalus to fishmeal replacement with alternative protein sources under biofloc technology (BFT) was assessed. Juvenile mullet (82.68 ± 0.05 g) were distributed among three dietary treatments with decreasing fishmeal inclusion levels of 15%, 5%, and 0%, corresponding to FM15, FM5, and FM0, respectively. After 27 days of feeding, intestinal samples were analyzed for microbiota composition, transcriptomic responses and enzymatic activity. The FM0 group exhibited reduced intestinal enzyme activity, whereas no significant differences were observed in terms of gut microbiota among the diets. Furthermore, transcriptomic analysis revealed differentially expressed genes associated with enriched GO terms and KEGG pathways related to lipid metabolism. This response was consistent with the lower mesenteric fat indices and whole-body lipid content observed in fish fed the FM0 diet, suggesting an early metabolic adjustment associated with complete fishmeal replacement and the higher dietary protein content. All diets exhibited high protein efficiency ratios (9.98 ± 2.42) and low feed conversion ratios (0.40 ± 0.17), with no significant differences observed among them. However, complete fishmeal replacement negatively affected intestinal physiology and lipid storage, indicating that these alterations were not fully compensated for by the biofloc system and may not be physiologically sustainable over longer periods. Further studies over an extended period could be carried out to evaluate the long-term effects of these diets., This work was supported by Grant TED2021-129272B-C21, funded by MICIU/AEI/10.13039/501100011033, and by the European Union NextGenerationEU/PRTR and the Generalitat Valenciana (GVA AICO/2021/198).

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+.

This dataset contains the experimental data generated during the evaluation of six commercially available paints as potential indoor radon barriers. It includes the raw radon concentration measurements recorded in the source and receiver chambers during 48-hour diffusion tests performed on filter paper substrates coated with a single coat of each paint, the main specifications of the experimental set-up used to perform the measurements, and the thickness measurements of the coated samples. The experimental data were used to determine 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 conference contribution. The experimental data were generated using a two-chamber radon diffusion test following a modified version of ISO/TS 11665-13:2017. The experimental set-up consisted of two sealed AISI 316L stainless steel chambers separated by the test sample. A sealed pitchblende stone (1.469 kBq) 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 connected in closed-loop circuits. Temperature and relative humidity were monitored throughout the experiments. Six commercially available water-based decorative paints were evaluated by applying a single coat of each paint onto a filter paper substrate. Two independent diffusion tests were performed for each paint. Each test lasted 48 hours, during which radon concentrations in the source and receiver chambers were recorded at 30-minute intervals. These raw experimental data were subsequently used to determine the radon concentration reduction and the radon diffusion coefficient following the procedure described in ISO/TS 11665-13:2017. The dataset also includes the main specifications of the experimental set-up, such as chamber characteristics, radon source activity and test area. The thickness of each coated sample was determined from eight measurements taken at different locations , from which the mean thickness and the standard deviation were calculated. The radon concentration data recorded by the RAD7 detectors at 30-minute 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 48-hour test. No additional processing, filtering or normalization was applied to the concentration data before their inclusion in the dataset. The experimental set-up specifications were compiled from the laboratory protocol used during the diffusion tests. For the thickness data, the reported mean thickness and standard deviation were calculated from eight thickness measurements taken at different locations on each coated sample.

The thickness of each laminated waste sample was determined from eight measurements taken at different locations on the sample, from which the mean thickness and the standard deviation were calculated. Following the recommendations of the ISO/TS 11665-13:2017, the thickness of materials installed with an overlap is the same as that of the material unbound, provided that the length on each side of the overlap exceeds the width of the overlap by at least 2 cm. The radon concentration data recorded by the RAD7 detectors at 30-minute intervals were exported.
