RICORDACI: Research on the Conservation, Restoration and Diagnosis of Cinematographic Films

This thesis is the result of the RICORDACI project, a three-year European-funded initiative involving the collaboration between the University of Bologna and the restoration laboratory of the Cineteca di Bologna, L'immagine Ritrovata, which aimed to develop innovative solutions and technologies for the preservation of cinematographic film heritage. In particular, this thesis presents new analytical methodologies to exploit two types of portable miniaturized Near Infrared spectrometers working in Diffuse Reflectance over the Short Wave Infrared (SWIR) range, to study the near infrared (NIR) spectral behavior of film base materials for an accurate, non-invasive and fast characterization of the polymer type; and for films with cellulose acetate supports, they can be employed as a diagnostic tool for monitoring the Degree of substitution (DS) affected by the loss of acetyl groups. The proposed methods offer non-invasive, fast, inexpensive and simple alternatives for the characterization and diagnosis of film bases to help the strategic planning and decision-making regarding storage, digitalization and intervention of film collections. Secondly, the thesis includes the evaluation of new green cleaning systems and solvents for the effective, fast and innocuous removal of undesired substances from degraded cinematographic films bases; these tests compared the efficiency of traditional systems and solvents against the new proposals. Firstly, the use of Deep Eutectic Solvent formulations for removing softened gelatin residues from cellulose nitrate bases; and secondly, the employment of green volatile solvents with different application methods, including the use of new electrospun nylon mats, for avoiding the dangerous use of friction for the removal of Triphenyl Phosphate blooms from the surface of cellulose acetate bases. The results obtained will help improving the efficiency of the interventions needed before the digitalization of historical cinematographic films and will pave the way for further investigation on the use of green solvents for cleaning polymeric heritage objects.

Verso una regolamentazione dei contratti intelligenti: particolare riferimento al settore finanziario

Esta tesis doctoral aborda un tema complejo y de actualidad. Complejo, porque no es posible estudiarlo desde un punto de vista jurídico, sin un conocimiento previo de la tecnología subyacente - el blockchain. Y de actualidad, porque esta tecnología ya ha tenido un profundo impacto en el sector financiero en general, coincidiendo con una tendencia reguladora en este campo que no tiene precedentes normativos en los que basarse. El mundo financiero, el derecho bancario, el derecho de valores y los contratos comerciales se enfrentan a retos que no se pueden ignorar. Este trabajo de investigación aborda esta tecnología desde una perspectiva jurídica, valorando en qué medida el ordenamiento jurídico se está adaptando al ritmo exigido; en qué medida el régimen jurídico vigente ofrece soluciones y puede aplicarse, con ligeras adaptaciones, a esta nueva realidad económico-comercial; y, por último, cuáles son los elementos y características diferenciales de las aplicaciones de la tecnología blockchain, que deben tenerse en cuenta para una adecuada regulación de las mismas, que responda a los problemas que plantean. Conocer los beneficios, riesgos y ventajas son elementos esenciales a considerar en el proceso de regulación, ya iniciado y guiado por la UE, en su voluntad de apostar por la innovación digital en la economía de la Eurozona.
