Development of urease enzyme inhibitors and assessment of their efficacy and ecotoxicity

This work study proposes novel and natural inhibitors of the enzyme urease, as more sustainable alternatives to the synthetic ones. Specifically, Deep Eutectic Solvents (DES) were used as an extractants and carriers of polyphenols extracted from waste biomass enriched in antioxidant compounds. The polyphenolic extracts with DES have been tested on lab-scale experiments to verify their effect on the reduction of the hydrolysis rate of urea-based fertilizers catalyzed by urease. The phytotoxicity and the soil ecotoxicity of DES and polyphenols formulations were then tested. DES resulted promising in terms of polyphenols extraction ability from biomass and as carriers of bioactive compounds in the agricultural field, showing non-damaging effects on plants (Avena sativa) and microarthropods in soil.

Mocku for change: an explorative study on the use of “mockumentary” as a new language for climate change education

In the ‘society of acceleration and uncertainty’ (Rosa, 2013), the young are struggling to interpret our complex and fast-changing world. The entity and the velocity of changes are so enormous that we need new narratives or languages to conceptualise them. Among those changes “Climate Change” is placed in a particular difficult position. As the writer A. Ghosh said: “The current climate crisis is also a crisis of culture, and thus of the imagination”. In fact, in today’s literature and cinema a strong dichotomy exists between fictional and non-fictional works, but none of those extremities seems suitable to picture an “adequate representation” of climate change issues, particularly those that are related to future. The main goal of my study, carried out within FEDORA EU project, was to understand to what extent the hybrid film form called “mockumentary” (a language that adopts the aesthetics of factual production to give an illusion of truth to invented stories) could inspire and help students in overcoming the mentioned dichotomy, working as a tool to foster the development of argumentative and imaginative skills needed to picture “immaginary yet realistic” climate change scenarios.
