Dynamic optical monitoring with an ESP32-CAM-based low-cost spectrophotometric prototype
No full textReal-time optical monitoring of large area dynamic color systems remains a technical challenge, particularly when aiming for low-cost, portable, and scalable solutions. In this study, we present a spectrophotometric platform based on an Arduino-compatible ESP32-CAM, a modular 3D-printed prototype, and a custom Python interface capable of reconstructing visible-range transmittance spectra (400–700 nm) from RGB images based on a neural network protocol. The system enables real-time visualization of both full spectral evolution and single-wavelength transmittance during any process of color switching, offering valuable insight into optical kinetics without requiring expensive instrumentation.
To validate its performance, thin films of five electrochromic polymers covering visible gamut color transitions (orange, magenta, cyan, green, and black) were analyzed under color-changing dynamic conditions. The transmittance evolution and reconstructed spectra obtained using the Arduino system were compared against those acquired from a reference spectrophotometer and a previously validated digital camera-based method. Results showed excellent agreement across most polymers, with deviations in transmittance values remaining below 4% even in the most challenging cases. The developed interface allows users to select specific areas of interest and control time resolution, while all data can be exported for further analysis. Additionally, all captured images are stored for subsequent high-accuracy post-processing using color correction and spectral reconstruction models. This work introduces a robust, accessible tool for dynamic optical analysis that maintains competitive performance compared to conventional systems. Its versatility, portability, and real-time functionality make it particularly suited for the in-situ optical evaluation of surfaces, smart materials and devices in both laboratory and field environments.This work was funded by the Spanish Ministry of Science and Innovation (MCIN)through project PID2022-139191OB-C32 and grant CNS2023-144331 funded by MCIU/AEI/10.13039/501100011033, “ERDF A way of making Europe”, and “European Union Next Generation EU/PRTR”

Evaluating astigmatid mites as alternative diets for Orius laevigatus: Effects on life history parameters
Get PDFIntegrated pest management (IPM) in greenhouse cultivation has benefited significantly from the use of predators such as Orius laevigatus. This beneficial insect, a natural enemy of thrips, can feed on pollen, facilitating preventive releases in flowering crops. However, in the absence of quality pollen, a supplementary food source is required to facilitate establishment. This study compared the performance of different populations of O. laevigatus, including wild and commercial populations and selected strains adapted to suboptimal pollen diets (1POL and 2POL), all fed with various species of astigmatid mites, a more economical alternative to traditional foods like Ephestia kuehniella eggs and Artemia cysts. The selected strains of O. laevigatus exhibited higher survival during nymphal development and greater fecundity when fed astigmatid mites compared to commercial populations. Among the astigmatid mites, Acarus siro was the best-performing diet, supporting high survival and acceptable development; however, it did not match the fecundity obtained with Ephestia kuehniella eggs. Acarus siro therefore represents a cost-effective supplementary or maintenance food, particularly suitable for sustaining populations in crops and for reducing reliance on Ephestia, especially when using genetically selected O. laevigatus strains that show enhanced performance on suboptimal diets.This research was funded by Grant PID2020-116897RB-I00 and PID2024-155785OB-I00 funded by MICIU/AEI/10.13039/501100011033.

Geotechnical aspects of decommissioning tailings storage facilities (TSF) in mining districts of Southern Spain
Get PDFProduction practices in the mining industry during the last century have left numerous inactive facilities that current administrations have to deal with. In the case of tailings storage, the risk of pollution dispersion or large-scale damage caused by stability failures requires specific actions. In southern Spain, 28 abandoned tailings dams in the mining districts of Mazarrón, Cartagena and La Unión and 59 in the mining districts located in Andalucian Provinces, have been classified as hazardous for potential pollution risk, according to European regulations. In this document, we gather the experiences of 23 case studies in tailing decommission projects planned during the 2010-24 period, focusing on the most recent case of the San Cristobal-II tailings dam (SC-II). The actions conducted consist essentially of sealing, introduction of drainage elements, slope reprofiling and surface revegetation. The geotechnical characterization and monitoring conducted during decommissioning have emphasized that action must focus on pore water pressure control throughout all the phases of the project. The analysis of the actions involved in the decommissioning projects shows some positive experiences but also the need to improve in-depth geotechnical data acquisition, to ensure long-term safety while optimizing the decommissioning costs.This work is a result of the research stay 22427/ EE/24 promoted by the Fundación Séneca-Agencia de Ciencia y Tecnología de la Región de Murcia and financed by the Programa Regional de Movilidad, Colaboración e Intercambio de Conocimiento “Jiménez de la Espada”.
