Flipped classroom in COVID-19 times: a cross-talking perspective

2020

La COVID-19 ha generado una serie de cambios en las diferentes esferas de nuestras vidas. Estos cambios han sido especialmente visibles en el ámbito educativo, donde ha sido necesario repensar los procesos formativos de forma urgente en términos de no presencialidad. En base a esta situación, el presente trabajo presenta una experiencia de Flipped learning llevada a cabo con los estudiantes del primer curso del Grado en Pedagogía de la Universitat de València. Asimismo, se propone un análisis sobre la concepción previa de los estudiantes sobre esta metodología y su percepción tras finalizar su implementación, ofreciendo una visión trasversal. Para ello, se ha recogido la información de los …

Enhancing in vivo exposure in the treatment of panic disorder and agoraphobia using location-based technologies: a case study

2019

Panic disorder (PD) is quite prevalent and often appears along with agoraphobia (PD/A). The treatment of choice is cognitive behavioral therapy (CBT). Transdiagnostic intervention, an emotion-focused, cognitive behavioral intervention that has led to the Unified Protocol (UP), emphasizes the common underlying mechanisms that contribute to the development and maintenance of emotional disorders such as PD/A. A core feature of this treatment approach is in vivo exposure (IVE) to feared situations, which aims to prevent avoidance behaviors and encourages the patient to confront feared situations gradually. It is a difficult component for patients, especially when implementing the exposure on t…

Analysis of surrogacy motherhood as a new technology in the biomedical and legal-philosophical field: technical advance, human recoil

2019

[EN] Surrogate motherhood is a question that has appeared in recent times, with increasing incidence, at present. The economic, political and media powers have brought a strictly technical concept to the public in order to familiarize them with this technique. This strategy has been based on the natural tendency to consider that any technological advance is good in itself, so that they have not been reviewed and made available to the citizens, in a reasonable manner, none of the issues that should be dealt with this technique. Thus, it is worth making a study of the regulations and jurisprudence of the assumptions that have been taking place and considering the reality that this formulation…

Diseño de tareas telecolaborativas para el aprendizaje de idiomas con cuentos del mundo

2018

Este artículo se centra en el diseño de tareas de telecolaboración para el desarrollo de competencias lingüísticas, literarias, interculturales y digitales, teniendo en cuenta las diferentes acciones llevadas a cabo antes y durante el proyecto de cara a garantizar el éxito del mismo. La propuesta, realizada en el marco del proyecto iTECLA, conjuga la telecolaboración con la redacción e intercambio de cuentos que reflejan valores culturales de los respectivos países de origen de los participantes.

Superfluorinated ionic liquid crystals based on supramolecular, halogen-bonded anions

2016

Unconventional ionic liquid crystals in which the liquid crystallinity is enabled by halogen-bonded supramolecular anions [CnF2 n+1-I⋯I⋯I-CnF2 n+1]- are reported. The material system is unique in many ways, demonstrating for the first time 1) ionic, halogen-bonded liquid crystals, and 2) imidazolium-based ionic liquid crystals in which the occurrence of liquid crystallinity is not driven by the alkyl chains of the cation. Out of the ordinary: The high directionality of halogen bonds and the fluorophobic effect were exploited in the design and synthesis of a new family of unconventional superfluorinated ionic liquid crystals. The liquid crystallinity of the system is driven by halogen-bonded…

Keggin heteropolyacid supported on BN and C3N4: Comparison between catalytic and photocatalytic alcohol dehydration

2020

The Keggin heteropolyacid (HPA), H3PW12O40 (PW12) has been supported on commercial boron nitride (BN) and two types of home prepared carbon nitride (C3N4). The supported PW12 was used in the gas-solid (photo)catalytic 2-propanol dehydration reaction to give propene at atmospheric pressure and temperatures in the range 70–120 °C and resulted more active than the pristine PW12. Reaction rate increased by increasing the temperature. Noticeably, the propene formation rate was higher by irradiating the catalytic system. The PW12/BN material resulted more active than PW12/C3N4. The acidity of the HPA cluster accounts for the catalytic role, whereas both the acidity and the redox properties of the…

ZrO2 Based materials as photocatalysts for 2-propanol oxidation by using UV and solar light irradiation and tests for CO2 reduction

2018

Abstract Bare ZrO2, Ce doped ZrO2 and Er doped ZrO2 samples have been prepared by a hydrothermal process and have been used as photocatalysts for 2-propanol oxidation reaction in gas solid regime. Moreover, some preliminary tests have been carried out for CO2 reduction. The samples were physico-chemically characterized and both bare and doped ZrO2 based materials resulted active for oxidation and reduction reactions by using UV and solar irradiation. The reactivity results have been correlated with the compositional, structural and morphological features of the photocatalysts.

Comparison of activity in the 2-propanol dehydration of supported heteropolyacid (photo)catalysts at the gas-solid interface

2015

Catalytic and photocatalytic tests for 2-propanol dehydration to propene were successfully carried out by using binary materials obtained by supporting a Keggin heteropolyacid H3PW12O40 (PW12) via impregnation method and/or solvothermal treatment. The supports used were commercial SiO2 (Mallinckrodt), TiO2 (Evonik P25) and multiwall carbon nanotubes (Sunnano) or home solvothermically prepared SiO2 and TiO2. (Photo)catalytic 2-propanol dehydration was studied in gas-solid regime by using a continuous (photo)reactor working at atmospheric pressure and 80 °C. the reaction was also studied by performing FTIR spectra of the gas-phase over the HPA-support composites, where the 2-propanol had been…
