La formazione e l’aggiornamento dei docenti chimici dell’Università di Palermo: le attività del Progetto Mentore e del TLC-CIMDU
The chemists of the University of Palermo are users, but also actors, of teacher training and faculty development. In 2019, the establishment of the TLCCIMDU was the natural evolution of the Project of Mentors for Teaching that began a >few years earlier with the aim to enhance teaching, which appeared to be a secondary activity with respect to research. This contribution describes these experiences by placing them in the broader context of pedagogical changes and technological transformations that affect the teaching-learning relationship in the twenty-first century.

La falsa identificazione del Santolinenone, componente fondamentale dell’olio essenziale di Santolina camaecyparissus
Luigi Francesconi published several articles on the identification of the main components of Santolina chamaecyparissus L. essential oil. He identified three ketones into the essence, giving the structure of santolinenone α and β. These compounds do not exist, and the erroneous identification derives from a wrong interpretation of the experimental available data as well as from the fact that he did not carry out decisive experiments for the identification of the structure.

Una separazione e i miscugli attraverso l’arte alla scuola dell’infanzia
1Stepping into the shoes of young scientists, the students of a homogeneous group in the final year of kindergarten tackled the topics of mechanical separation through centrifugation, and downstream, homogeneous and heterogeneous mixtures through an interdisciplinary approach that intertwined science with art, food education, and civic education.

Inquinamento da particolato a Mottola e aspetti educativi
1The aim of the work is the assessment of particulate air pollution in Mottola in 2022 and the treatment of socio-educational aspects. Measurements of PM 2,5 and PM 10 were made with a laser scattering instrument, both outdoor, in three selected sites, and indoor, in three schools and in three pharmacies. As for the outdoor sites, data analysis shows some high values in the winter period and an annual average of the data collected in the normal limit. The values collected in schools and pharmacies are acceptable, except for one in October, in correspondence to an outdoor peak. Data on Covid-19 infections and bronchodilators used do not correlate with PM 2,5 and PM 10 peaks. Useful suggestions for managing problems caused by particulate matter are given in the conclusions.

Quanto è “verde” il PNRR? Le par Quanto è “verde” il PNRR? Le parole e i fatti
The article examines the “green” Mission 2 of the PNRR which concerns the energy aspects of the ecological transition with the aim of verifying the progress of its development. In particular, the essential elements of the Component 2 of this Mission are examined. It emerges that the promotion of renewable energy is heavily penalised, whereas research and development of hydrogen and development of charging station installations for electric cars are taken in consideration. The rapid progress in biomethane production, which however does not solve the problem of decarbonization, is also considered.
