Erizos, mirlitas y otros animales de cuento Relatos de las tradiciones orales de Argelia, España, Italia y Marruecos
(Ediciones de la Universidad de Castilla-La Mancha, 2025-11) López Bernal, Desirée; Mañero Lozano, David; Sanfilippo, Marina; Sánchez Ortiz, César
Los seis cuentos que se presentan en este libro proceden de las tradicionales orales de Argelia, España, Italia y Marruecos. De ser palabra oral, han pasado a estas páginas para que niños (y sus mayores) se diviertan con ellos, aprendan valores fundamentales y disfruten del acto lúdico y creativo que es narrar, en un proceso circular de puesta en valor de la tradición oral que termine devolviéndolos a su medio original.

Engineering clean solutions: A life cycle perspective on electrochemical ozone generation
(ELSEVIER, 2025) Rodríguez Gómez, Alberto; Castro Castro, María del Pilar; Sáez Jiménez, Cristina; Fernández Marchante, Carmen María; Rodrigo Rodrigo, Manuel Andrés
This study presents a rigorous Life Cycle Assessment (LCA) and Life Cycle Costing Analysis (LCCA) of electrochemical ozone production using proton exchange membrane (PEM) electrolyzers. A fully integrated bench-scale system was designed and operated continuously for 1,000 hours to generate high-quality empirical data. The plant was engineered with precise mass and energy balances, ensuring scalability and methodological consistency. This effort elevated the system’s Technology Readiness Level (TRL) from 4 to 5, bridging the gap between lab-scale research and industrial application. LCA results identified electricity consumption (particularly from the Spanish grid) as the primary driver of environmental impacts, including carbon footprint, human toxicity, and freshwater ecotoxicity. Equipment and material contributions were more significant in the water footprint. Importantly, replacing grid electricity with photovoltaic energy reduced environmental impacts by up to 80 %. Economically, the technology demonstrated promising performance, with capital and operational costs estimated at €2.43 and €0.55 per gram of ozone, respectively, at 100 mA·cm-2. These findings highlight the strong potential of electrochemical ozone generation as a sustainable and cost-effective alternative to conventional methods, especially when integrated with renewable energy sources.

Criptomonedas y Derecho penal: Más allá del blanqueo de capitales. En Revista electrónica de ciencia penal y criminología
(Universidad de Granada, 2021) García Moreno García de la Galana, Beatriz
Money laundering and financing of terrorism regulations are the best known aspect of the criminal regulation of crypto currencies. However, the challenges posed to criminal law by these virtual currencies are more diverse and this paper focuses on them. In the first part, it reflects on the convenience of protecting through criminal law the monopoly of the States against the issuance of virtual currencies and cryptocurrencies. The second part deals with the protection of the cryptocurrencies user as consumers, analyzing three types of behaviors: frauds that take place at the moment of the acquisition of cryptocurrencies or at their launch, operations similar to market abuse in the cryptomarket, and finally, the protection of cryptocurrencies as a means of payment, an aspect that is dealt with in the recent European Directive 2019/713.

Carboxylic acids selective recovery from wastewater using electrodialysis
(ELSEVIER, 2025) Richa Richa, Maya; García Cervilla, Raúl; Lobato Bajo, Justo; Cañizares Cañizares, Pablo; Rodrigo Rodrigo, Manuel Andrés
Carboxylic acids (CAs), such as oxalic acid and acetic acid, are valuable by-products formed during the partial oxidation of organic matter in wastewater treatment. Conventional advanced oxidation processes focus on mineralization, often at high costs, without recovering these useful compounds. This study aims to explore electrodialysis (ED) as a sustainable alternative to separate and purify these acids, adding value to wastewater treatment processes. To do this, in this work, the influence of current density on the efficient purification of oxalic acid from a mixture of four carboxylic acids was studied. Experiments were conducted using a four-compartment electrodialysis cell equipped with the appropriate anion and cation exchange membranes. Key parameters were validated by examining the migration and recovery rates of acids under controlled experimental conditions. A current density of 25 mA/cm² was found to be the most effective for the purification of oxalic acid, achieving higher recovery than other higher and lower current densities. With these results, this study highlights electrodialysis as a viable approach for the selective separation and purification of carboxylic acids. Careful optimization of operational parameters enables efficient acid recovery, enhancing the economic and environmental sustainability of wastewater treatment systems.
