    Lavoisier’s first Memoir on Respiration – year 1777

    by Roberto Poeti 2 March 2023
    2 March 2023

    Presentation of Lavoisier’s Memoir : “EXPERIMENTS ON ANIMAL RESPIRATION” – year 1777 The main way to introduce the history and epistemology of chemistry into teaching is to use the memoirs, essays and pages of texts written by the protagonists of chemistry as a fundamental tool. I translated into english from French, I think for the first time, the memoir that…

    28 July 2021

    The museum   I think there cannot be such a strong emotion for a chemist as that one feels when visiting Mendeleev’s apartment at the University of St. Petersburg. He lived there from 1867 to 1890. The apartment is located on the ground floor of the Faculty of Chemistry and was connected to his laboratory. Since 1911, four years after his…

    The “Sepulcher” of Antoine Lavoisier The article tells the random discovery made during a short stay in Paris, in search of the places of the history of chemistry. The visit to the catacombs of Paris, one of the many tourist destinations, made us known, through an exhibition set up there, where are the mortal remains of the father of chemistry.

    The history of distillation up to the 18th century

    by Roberto Poeti 2 January 2021
    2 January 2021

    A long story The history of distillation is closely linked to that of alcohol. The mention of distilling devices can be found in the authors of ancient Greece. But these tools were very primitive because they consisted of boilers heated over a high heat on which a layer of sponges was placed which collected the vapors, condensed them and then…

    The Tragic Story of a Great Chemist: Archibald Scott Couper (1831-1892)

    by Roberto Poeti 26 March 2020
    26 March 2020

    Carbon Chemistry In the history of Organic Chemistry, to the German chemist Friedrich August Kekulé von Stradonitz (1829 – 1896) is reserved for a pre-eminent place. In 1858 he wrote an article listing two fundamental properties of the carbon atom: valence four and the ability of carbon atoms to bind together. In 1865 he published another paper in which he…
