Deposizione elettrochimica di esacianoferrato di rame tramite un metodo "a due step"; caratterizzazione e valutazione delle prestazioni

In this thesis we have identified two electrochemical procedures for preparing two compounds of copper hexacyanoferrate (CuHCF) films with different compositions and structures. The deposition were carried out using a “two steps” method consisting in electrochemical oxidation of previously deposited metallic copper on carbon substrates (glassy carbon and graphite foil electrodes) in K3[Fe(CN)6] solution. Both films, CuHCF-methodA and CuHCF-methodB, were characterized by cyclic voltammetry (GC) and their study using XANES spectroscopy revealed evidence of different structures. Additionally, insertion and extraction of different cations (Na+, K+, Mg2+, Al3+ and Cs+) were performed and the results indicate that CuHCF-methodA has slightly better performances and operational stability than CuHCF-methodB. Data from galvanostatic charge-discharge tests confirme the latter observation. An application for amperometric detection of H2O2 and SEM micrographs are also reported for both films (method A and B). Comparing these results with a previous work of our research group, seems that the deposition of two different compounds using methodA and methodB is due to the different stoichiometry of ions Cu2+ e [Fe(CN)6]3– created near electrode surface during the dissolution step.

“È per un bambino o una bambina?” Stereotipi di genere nella letteratura per l'infanzia: proposta di traduzione di due albi illustrati

The aim of this dissertation is to propose a translation into Italian of two American picturebooks: Is That For a Boy or a Girl? written by S. Bear Bergman and illustrated by Rachel Dougherty, and Jacob's New Dress written by Sarah and Ian Hoffman and illustrated by Chris Case. The common thread of the two books is the critique of gender stereotypes in children’s literature and in other aspects of childhood at large, such as gender expression. The two titles were in fact selected from the bibliography created by the European project G-BOOK (Gender Identity: Child Readers and Library Collections), which was spearheaded by Centro MeTRa, an Italian research centre affiliated with the University of Bologna which aims to promote gender-positive and inclusive literature. The thesis is divided into four chapters, the first of which is devoted to a discussion of children's literature as a whole and to the analysis of the illustrated fiction subgenre, the category to which the above-mentioned volumes belong. The second chapter focuses on diversity, highlighting its key role in education and the relevant trends in publishing and translation studies. The third chapter consists of a brief presentation of the works I have chosen. Following the introduction of the plot and the biography of the authors, the chapter focuses on the analysis of the two illustrated books from a linguistic, stylistic, iconographic and commercial point of view, in preparation for translation. Finally, in the fourth chapter I present my translation proposal, complete with a commentary on the problems I encountered and the translation techniques that allowed me to overcome them.
