Stanislao Cannizzaro and the Development of Chemistry in Palermo from 1862 to 1871
2009
Stanislao Cannizzaro worked at Palermo University for about ten years. There he managed to establish a modern and well-equipped chemical laboratory. His international fame attracted co-workers even from abroad: Naquet, Lieben, and Körner came to Palermo to work with him. This greatly improved the quality of teaching and of research in Palermo, which became a worldwide acknowledged center of chemical culture. In Palermo, atomic-molecular theory was extensively taught and research was carried out on chemical atomicity (valence) and spatial structures of both aliphatic and aromatic organic molecules: Körner found the relative positions of substituent groups on the benzene ring, Paternò proved …

Pedro Gutiérrez Bueno (1743-1822) y las relaciones entre la química y la farmacia durante el último tercio del siglo XVIII
2001
This paper is part of a general research project on the role that chemistry played in transforming experimental pharmacology during nineteenth-century Spain. Within this general framework, this paper deals with the main characteristics of chemistry textbooks written by Pedro Gutiérrez Bueno (1745-1822), a pharmacist who taught chemistry in several institutions during the late eighteenth century. In an earlier paper, we have analysed the intended public of the first edition of Gutiérrez Bueno`s textbook. This paper deals with the changing institutional context in which the second edition was published. This issue is closely connected with substantial transformations in the relationship betwe…
From Masurium to Trinacrium: The Troubled Story of Element 43
2005
The first man-made chemical element was that with atomic number 43. It was produced at the University of Californiaâ€sA„A¬Berkeley (by neutron bombardment of a molybdenum plate and was chemically identified at the University of Palermo (Italy) in 1937 by Segre and Perrier. Previous attempts to identify it in natural ore had been unsuccessful, owing to the short life of its isotopes. Notwithstanding, several claims of its discovery had appeared in the chemical literature. The history of this discovery clearly shows the dramatic improvements of chemical analytical techniques and criteria in the first half of 20th century. In 1949 its discoverers proposed to call it technetium, which means pro…

Esperienze di Debate all’Università di Palermo
2023
Introduzione Il Progetto Mentore per la didattica dell'Università di Palermo è un’esperienza di formazione e miglioramento della didattica universitaria a cui partecipiamo su base volontaria da alcuni anni. Le attività del Progetto includono anche la formazione su alcune specifiche metodologie didattiche, ma contemporaneamente, attraverso il confronto e il dialogo tra pari, incentivano la ricerca e l’elaborazione di nuovi percorsi didattici all’interno dei rispettivi insegnamenti. In questo contesto, su iniziativa autonoma e attraverso una formazione da autodidatti, abbiamo sperimentato in due insegnamenti di Corsi di Laurea di ambito disciplinare diverso (Giurisprudenza e Chimica) la metod…
