Ballistic transmittance and transparency measurements; XRD patterns; ellipsometry spectra and fittings; transmission and reflection measurements; SEM image of SiO2 NP thick films; PL excitation spectra, PL decay and PLQY measurements; normalized TL glow curves and time-dependent afterglow decays; results of ellipsometry fits, results of UMA fits, and parameters used to fit luminescence kinetic scans using the local model, Tailoring the unique delayed and long-lasting luminescence of persistent phosphors is crucial for their application in anticounterfeiting, data storage, imaging displays, and AC-driven lighting. We introduce a novel strategy to achieve this by modifying the refractive index of persistent phosphor transparent coatings. Specifically, we developed ZnGa2O4:Cr3+/SiO2 nanocomposite films with tunable refractive indices from 1.45 to 1.7. This tunability allowed us to precisely control the Cr3+ radiative decay rate, resulting in a substantial 1.7-fold increase in both luminescence and afterglow brightness. Furthermore, our approach uniquely influences the intrinsic charging rate of the phosphor, a mechanism attributed to the strain induced on the ZnGa2O4:Cr3+ nanocrystals by the presence of SiO2. This work demonstrates an unprecedent ability to manipulate the afterglow kinetics without altering the material composition, opening new avenues for designing and optimizing persistent luminescence materials., Peer reviewed

Under a Creative Commons BY-NC 4.0 International license., Table S1 shows physical properties of oxygen carrier at different operating times. Crushing strength, attrition rate, porosity, density, and magnetic permeability were determined as the function of the fuels, redox cycle and operation time. Table S2 illustrates the phase composition of the fresh oxygen carrier and the transformations that occur during combustion. As observed, free copper oxide disappears, while Cu0.5MnFe1.5O4 becomes the dominant phase, replacing the initial spinel phase Cu0.5Mn0.5Fe2O4. This phase transition indicates a structural evolution in the oxygen carrier during prolonged combustion. Phase analysis was performed on the fines generated during the experiments, as presented in Table S3. The dominant phase in the fines was identified as Cu0.5MnFe1.5O4, which closely aligns with the phase composition of the main oxygen carrier particles under the same test conditions. This similarity suggests that the fines originate primarily from the bulk oxygen carrier material, maintaining a consistent phase structure despite the attrition process., This work was supported by Grant PDC2021-121190-I00 funded by MCIN/AEI/10.13039/501100011033 and by the European Union NextGenerationEU/PRTR.

This dataset is made available under a CC-BY license (https://creativecommons.org/licenses/by/4.0/), Aspergillus carbonarius is one of the main species responsible for wine, coffee and cocoa toxin contamination. The main mycotoxin produced by this fungus, ochratoxin A (OTA), is a secondary metabolite categorized as a possible carcinogen because of its significant nephrotoxicity and immunosuppressive effects. A polyketide synthase gene (otaA) encodes the first enzyme in the OTA biosynthetic pathway. It is known that the filamentous fungi, growth, development and production of secondary metabolites are interconnected processes governed by global regulatory factors whose encoding genes are generally located outside the gene clusters involved in the biosynthesis of each secondary metabolite, such as the veA gene, which forms part of the VELVET complex. Different fungal strains compete for nutrients and space when they infect their hosts, and safer non-mycotoxigenic strains may be able to outcompete mycotoxigenic strains during colonization. To determine the possible utility of biopesticides based on the competitive exclusion of mycotoxigenic strains by non-toxigenic ones, we used A. carbonarius ΔotaA and ΔveA knockout mutants. Our results showed that during both in vitro growth and infection of grapes, non-mycotoxigenic strains could outcompete the wild-type strain. Additionally, the introduction of the non-mycotoxigenic strain led to a drastic decrease in OTA during both in vitro growth and infection of grapes., The work was partially cofunded by Projects RTI2018-093392-A-I00 and PID2021-126005OB-I00 (MCIN /AEI /10.13039/501100011033 / FEDER, UE) and by Project AGROALNEXT/2022/028 (GVA, PRTR, MRR, NextGenerationEU).

[Description of methods used for collection/generation of data] In this study, two methodologies (destructive and non-destructive) were developed and tested to quantify aboveground and belowground biomass, and their carbon content, in 7.5-year-old trees of two widely cultivated olive cultivars (Arbosana and Picual), at field and under Mediterranean climate conditions., [Methods for processing the data] Differences between levels of the evaluated factors for the different measured variables were assessed using the parametric ANOVA or t-student test depending on the number of levels for the three evaluated factors (two and more than two respectively), after checking that the data met the normality, homogeneity of variances, randomness and independence hypotheses. When the assumptions of normality were not met, the non-parametric Kruskal Wallis test or the Mann-Whitney U test was carried out. Once parametric or non-parametric tests were applied, the mean values of the different levels were separated using Tukey’s post-hoc multiple comparisons test with a significance level of 5%. In those cases where the hypothesis of homogeneity of variances was not met, the Games-Howell method was applied., [EN] Accurate quantification of biomass production and carbon accumulation in olive orchards is crucial for optimizing their agronomic management and assessing their potential to mitigate climate change negative impacts. In this study, two methodologies (destructive and non-destructive) were developed and tested to quantify aboveground and belowground biomass, and their carbon content, in 7.5-year-old trees of two widely cultivated olive cultivars (Arbosana and Picual), at field and under Mediterranean climate conditions. Picual accumulated more biomass (36.5 kg tree⁻¹) than Arbosana (27.5 kg tree⁻¹), mainly due to a greater investment in components like trunk and non-primary branches. Conversely, Arbosana allocated more biomass to leaves. In both cultivars, around 60% of the root biomass was at the top 25 cm of soil, and over 55% was concentrated in the root ball. Weighted average carbon concentration was 47% in aboveground biomass and 42% in roots. At the orchard scale, soil was the main organic carbon pool, around 76 t C ha-1, compared to 13-16 t C ha-1 in the total olive tree biomass. Average annual carbon accumulation rate in olive biomass ranged from 1.68 t C ha-1 yr-1 (Arbosana) to 2.16 t C ha-1 yr-1 (Picual), within the range of C fixation rates in Mediterranean agroecosystems. Destructive sampling captured cultivar differences in biomass and C content more accurately, whereas non-destructive method proved more suitable and accessible for large-scale use. These results help integrate biomass and C content data into olive genotype selection and management strategies, to increase carbon sequestration and sustainability of olive grove systems., [ES] La cuantificación precisa de la producción de biomasa y la acumulación de carbono en los olivares es fundamental para optimizar su manejo agronómico y evaluar su potencial para mitigar los efectos negativos del cambio climático. En este estudio se desarrollaron y evaluaron dos metodologías (destructiva y no destructiva) para cuantificar la biomasa aérea y subterránea, así como su contenido de carbono, en árboles de 7,5 años de edad de dos cultivares de olivo ampliamente cultivados (Arbosana y Picual), en condiciones de campo y bajo clima mediterráneo. Picual acumuló una mayor biomasa (36,5 kg árbol⁻¹) que Arbosana (27,5 kg árbol⁻¹), principalmente debido a una mayor inversión en componentes como el tronco y las ramas no primarias. Por el contrario, Arbosana asignó más biomasa a las hojas. En ambos cultivares, aproximadamente el 60 % de la biomasa radicular se encontró en los primeros 25 cm del suelo, y más del 55 % se concentró en el cepellón. La concentración promedio ponderada de carbono fue del 47 % en la biomasa aérea y del 42 % en las raíces. A escala de plantación, el suelo representó el principal reservorio de carbono orgánico, con alrededor de 76 t C ha⁻¹, en comparación con 13–16 t C ha⁻¹ en la biomasa total del olivo. La tasa media anual de acumulación de carbono en la biomasa del olivo varió entre 1,68 t C ha⁻¹ año⁻¹ (Arbosana) y 2,16 t C ha⁻¹ año⁻¹ (Picual), dentro del rango de tasas de fijación de carbono reportadas para los agroecosistemas mediterráneos. El muestreo destructivo permitió captar con mayor precisión las diferencias entre cultivares en biomasa y contenido de carbono, mientras que el método no destructivo resultó más adecuado y accesible para su aplicación a gran escala. Estos resultados contribuyen a integrar los datos de biomasa y contenido de carbono en la selección de genotipos de olivo y en las estrategias de manejo, con el fin de incrementar el secuestro de carbono y la sostenibilidad de los sistemas olivareros., This work has been supported by the projects MARVIC “Monitoring, reporting and verification of soil carbon and greenhouse gases balance” (101112942), ECOMED "Improving soil cover assessment strategies in Mediterranean agricultural areas” (PR.
