[ES]En este artículo se presenta una experiencia de innovación que se ha articulado, en el seno de un diseño curricular a través de módulos, al objeto de mejorar los procesos de enseñanza-aprendizaje que se están desarrollando en la Facultad de Fª y Ciencias de la Educación de la UPV/EHU. El marco de innovación aprovecha la oportunidad surgida con la configuración de los nuevos planes de estudio para su convergencia en el Espacio Europeo de Educación Superior. El contexto más amplio en el que se enmarca esta experiencia, es el de los cambios organizativos, curriculares y culturales, que está suponiendo la realización de un diseño modular de las nuevas titulaciones de grado (Pedagogía y Educación Social), trabajando en equipos docentes coordinados y contando con el apoyo institucional de la UPV/EHU. La innovación concreta que se presenta, describe minuciosamente uno de los siete módulos que componen la nueva titulación del Grado en Educación Social, y subraya la labor desplegada por el equipo docente que imparte las cinco materias que conforman el módulo en las dos lenguas oficiales: euskara y castellano, al planificar, desarrollar y evaluar la actividad interdisciplinar que les compete de manera coordinada. En este trabajo se reflexiona respecto a las posibilidades que la estructura modular ofrece para acometer un cambio real en la cultura de la práctica docente, y a cómo gestionar factores clave que garanticen el tránsito a un modelo docente activo, participativo y colaborativo. // This paper presents an innovative approach to improving teacher quality that is being developed at the Faculty of Philosophy and Educational Sciences of the UPV / EHU, taking the opportunity arose with the configuration of the new curricula for their convergence in the European Higher Education Area. It is framed in the broader context of organizational change, curriculum and cultural, that is assuming the implementation of a modular design of the new degree (Education and Social Education), working in teams coordinated and with the institutional support of the UPV. The concrete innovation is presented, describes one of the seven modules of the new degree of Social Education, and underlines the work done by the faculty team who teach the five subjects that make up the module in the two official languages: Basque and Spanish, because they must plan, develop and evaluate the interdisciplinary activity in a coordinated manner. We reflect in this paper on the potential that the modular structure offers to undertake real change in the culture of teaching practice, and how to manage key factors to ensure the transition to a teaching model active, participatory and collaborative.

A solid state lithium metal battery based on a lithium garnet material was developed, constructed and tested. Specifically, a porous-dense-porous trilayer structure was fabricated by tape casting, a roll-to-roll technique conducive to high volume manufacturing. The high density and thin center layer (< 20 μm) effectively blocks dendrites even over hundreds of cycles. The microstructured porous layers, serving as electrode supports, are demonstrated to increase the interfacial surface area available to the electrodes and increase cathode loading. Reproducibility of flat, well sintered ceramics was achieved with consistent powderbed lattice parameter and ball milling of powderbed. Together, the resistance of the LLCZN trilayer was measured at an average of 7.6 ohm-cm2 in a symmetric lithium cell, significantly lower than any other reported literature results. Building on these results, a full cell with a lithium metal anode, LLCZN trilayer electrolyte, and LiCoO2 cathode was cycled 100 cycles without decay and an average ASR of 117 ohm-cm2. After cycling, the cell was held at open circuit for 24 hours without any voltage fade, demonstrating the absence of a dendrite or short-circuit of any type. Cost calculations guided the optimization of a trilayer structure predicted that resulting cells will be highly competitive in the marketplace as intrinsically safe lithium batteries with energy densities greater than 300 Wh/kg and 1000 Wh/L for under $100/kWh. Also in the pursuit of solid state batteries, an improved Na+ superionic conductor (NASICON) composition, Na3Zr2Si2PO12, was developed with a conductivity of 1.9x10-3 S/cm. New super-lithiated lithium garnet compositions, Li7.06La3Zr1.94Y0.06O12 and Li7.16La3Zr1.84Y0.16O12, were developed and studied revealing insights about the mechanisms of conductivity in lithium garnets.
