[EN] This research work studies the development of an electrochemical cell prototype based on textile electrodes for treating wastewater via electrochemical processes. The present prototype proposes a system that offers greater efficiency regarding the size/surface of electrodes in electrolysis processes. This prototype enables the treatment of large volumes of dissolution. Moreover, this prototype could surface modify textile electrodes by an electrochemical process in the same cell, specifically, an electrochemically reduced graphene oxide intermediate layer and an outer layer of electrochemically reduced metal nanoparticles are proposed. Surface modification by reduced graphene oxide increase the textile electrode’s stability, conductivity, and specific surface, whilst Pt nanoparticles increase electroactivity. Amaranth was selected to validate the use of this prototype in treating emerging pollutants. This is an azoic dye with a simple structure. Various analytical techniques demonstrate that colour removal takes place with an electrical energy consumption of between 0.29 and 4.66 kWh m−3 (depending on the operational specifications of the electrolysis performed). Once the colour is removed, total organic carbon and chemical oxygen demand decreases by up to 49% and 37%, respectively., This research is part of the Spanish R+D+i contract (TED2021-130905B-I00 funded by MCIN/ AEI/10.13039/501100011033 and the “European Union NextGenerationEU/PRTR”).

[EN] Dataset asociated to the paper "Above and belowground male population of the Invasive Cit-rus mealybug Delottococcus aberiae De Lotto (Hemiptera: Pseudococcidae) " The invasive Delottococcus aberiae is one of the most harmful mealybugs on citrus in Spain, since it causes deformations and the premature falling of fruits. To improve control strategies, this study evaluates its population above and belowground, distri-bution in the soil and identify natural enemies emerging from belowground of citrus orchards. The distribution in the soil of emerged males varies significantly with the distance to the tree trunks with an annual average number of 0.95 males/trap/day at 0.5 m, and ranging between 0.25-0.32 at 1 m, 1.5 m and 2 m. There is a constant emergence of males throughout the year, both aboveground and belowground, with four distinct peaks, the first two occurring in February and April. This observation is essential to manage fruit damages that follows between March and June. Among the natural en-emies detected belowground the following are highlighted: Bdellidae mites (52%), Hymenoptera parasitoids (16%) and spiders (11%). When implementing IPM strate-gies, emphasis should be placed on adequate soil management (crops, mulching, or the release of natural enemies) and to the appearance of first generation. We propose a belowground population sampling method as a simple and practical tool to quantify this pest’s the winter and spring populations, which remain undetectable using current methodologies., This research was funded by the Next Generation European Union and the Plan de Recuperación, Transformación y Resiliencia of the Spanish Government, with the support of Generalitat Valenciana (project AGROALNEXT/2022/043), and by the project “Ruralfruit-AgroEco” (Transición al modelo agroecológico y adaptación al cambio climático de la citricultura convencional en Cooperativas valencianas” (project AGCOOP_A/2022/015), subsidized by the PDR-CV 2014-2020 (53% UE, 8,86% MAPA, 38,14% GVA)

[EN] Ti-felt electrodes with high surface area have been used as supports of electroactive coatings (Pt and SnO₂–Sb–Pt). The electrodes obtained have been employed for the electrochemical oxidation of polystyrene nanoplastics (NPs) (100 nm) in solution. Voltammetric characterization of the electrodes with Ru(NH₃)₆Cl₃ and K₃Fe(CN)₆ redox mediators showed a substantial increase in the redox peaks' current density compared to the boron‑doped diamond electrode. For example, this increase was >68‑fold for the SnO₂–Sb–Pt electrode when using the Ru(NH₃)₆Cl₃ redox mediator. This can be attributed to the enhanced surface area of Ti‑felt, composed of 20 μm diameter fibers, and the roughness of the electrocatalyst coatings. Voltammetric characterization of Ti‑Pt and Ti‑SnO₂–Sb–Pt in 0.03 M Na₂SO₄ media showed an increase in the anodic current density when adding NPs, which would account for a direct mechanism of electrooxidation of the electrode. •OH, S₂O₈²⁻, H₂O₂, and O₃ generation were also determined for both types of electrodes. The degradation of NPs was monitored by fluorescence spectroscopy, taking advantage of the fluorescence of styrene. In addition, it was observed that the dispersion of the second‑order diffraction light (this phenomenon takes place in the diffraction grating of the monochromator) by NPs could also be used to monitor the evolution of the NPs concentration in solution. The electrochemical degradation of polystyrene NPs was faster with SnO₂–Sb–Pt modified Ti‑felt‑based electrodes than with the Pt‑modified one (reaching 90 % degradation in 100 and 210 minutes at 25 mA·cm⁻², respectively). Electrochemical energy consumption per order was also lower for SnO₂–Sb–Pt‑modified electrodes., This research is part of the Spanish R+D+i contract TED2021-130905B-I00 funded by MCIN/AEI /10.13039/501100011033 and by the European Union NextGenerationEU/PRTR as well as the Red E3Tech Plus: Proyecto Redes de Investigación de la AEI Network E3Tech PLUS (RED2022-134552-T) project.

[EN] The resulting solutions from the cotton fabrics dyeing using the trichromy Procion HEXL, with NaCl as electrolyte, were electrochemically treated. These dyes have two azo groups as chromophores and two monochlorotriazinic groups as reactive groups in their structure. The combined oxidation/reduction at 125 mA cm-2 in a filter-press cell without compartment separation was carried out using an anode of Ti/SnO2eSbePt and a cathode of stainless steel. This procedure has been effective in previous experiments using sulphate as electrolyte. A significant decrease in total organic carbon (TOC), chemical oxygen demand (COD), and total nitrogen (TN) was obtained. Moreover, the process took place efficiently. The average oxidation state (AOS) and the carbon oxidation state (COS) data confirmed the presence of stable oxidized intermediates in the electrolysed solution. The chromatography and the UVeVisible spectrophotometry assays indicated that full decolourisation is obtained at a loaded charge of around 0.81 Ah L-1 which is associated with an electrical energy per order (EEO) of 1.20 kWh m-3., The authors wish to thank the Spanish Agencia Estatal de Investigación (AEI) and European Union (FEDER funds) for the financial support (contract MAT2016-77742-C2-1-P and Red E3Tech CTQ2017-90659-REDT).

[EN] Microplastics and nanoplastics have arisen as contaminants of emerging concern due to the wide use of plastics, and the application of boron-doped diamond (BDD) electrodes for their removal is promising. In this study, we report the influence of BDD doping levels (500, 2500, and 10000 ppm B doping) on the electrooxidation of polystyrene nanoplastics (100 nm, 20 mg⋅L-1). Different current densities (50, 25, 12.5, and 5 mA⋅cm-2) have been applied to determine the best electrolysis conditions for each electrode type. In addition, hydroxyl radical (•OH), persulphate (S2O82-), and hydrogen peroxide (H2O2) reactive species have been determined to understand the influence of the species generated on the degradation of NPs. BDD500 electrode presents the fastest degradation of PS NPs at low current densities (12.5 and 5 mA⋅cm-2), BDD2500 at 25 mA⋅cm-2, and BDD10000 at 50 mA⋅cm-2. Among oxidative species determined, S2O82- is the one generated with the highest concentration and seems to command the degradation of PS NPs, since at 25, 12.5, and 5 mA⋅cm-2, the electrodes that produce more S2O82- degrade faster PS NPs. At 50 mA⋅cm-2, the differences between the different electrodes were minimal. The highest mineralization (as measured by non-purgeable organic carbon measurements) was obtained for BDD500 at 50, 25, and 12.5 mA⋅cm-2, and BDD2500 at 5 mA⋅cm-2., This research is part of the Spanish R +D +i contract TED2021-130905B-I00 funded by MCIN/AEI /10.13039/501100011033 and by the European Union NextGenerationEU/PRTR as well as the Red E3Tech Plus: Proyecto Redes de Investigación de la AEI Network E3Tech PLUS (RED2022-134552-T) project.
