| dbo:abstract | جورج يموان (بالفرنسية: Clément Georges Lemoine) هو كيميائي فرنسي، ولد في 16 يناير 1841 في Tonnerre في فرنسا، وتوفي في 13 نوفمبر 1922 في باريس في فرنسا. (ar) Clément Georges Lemoine (16 January 1841 in Tonnerre – 13 November 1922 in Paris) was a French chemist and hydrologist. He was the father of geologist Paul Lemoine (1878–1940). He studied at the École Polytechnique and the École des ponts et chaussées, obtaining a doctorate in physical sciences in 1865. For many years he was associated with the École Polytechnique in Paris, where he ultimately served as a professor of chemistry from 1898 to 1911. In 1866 he began work as an engineer in charge of hydrometric services in the Seine Basin. In 1881 he was appointed chief engineer of bridges and roads, and in 1901, was named inspector general of bridges and roads. He is credited with organizing a flood warning service throughout France. As a chemist he discovered phosphorus sesquisulfide, a compound that will later be used in the manufacture of matches. He continued research on the allotropic transformation of phosphorus, and was also the author of works on chemical equilibria. In 1899 he became a member of the Académie des sciences (chemistry section), of which in 1921, he was named its president.

(fr) Clément Georges Lemoine (Tonnerre, 26 giugno 1841 – Parigi, 13 novembre 1922) è stato un chimico francese, noto principalmente per la sintesi del sesquisolfuro di fosforo e per i suoi studi sugli equilibri chimici. La carriera scientifica di Lemoine si divide tra ingegneria e chimica. Entrò nella École polytechnique nel 1858 e nel 1860 divenne studente a l'École nationale des ponts et chaussées (Scuola di ponti e strade) e ne ottenne il titolo di ingegnere. Insegnò nel Politecnico dove divenne professore nel 1897. Nel 1901 fu nominato ispettore generale di ponti e strade di Parigi, e organizzò un sistema di allarme contro le inondazioni. Nel 1899 divenne membro dell'Accademia delle scienze francese, e ne fu presidente nel 1921. Per quanto riguarda la chimica, fu il primo a descrivere il sesquisolfuro di fosforo nel 1864. Questo composto rimase una curiosità chimica finché a partire dal 1898 non venne utilizzato per la fabbricazione dei fiammiferi. Diede inoltre notevoli contributi alla conoscenza degli equilibri chimici. Studiò le trasformazioni tra gli allotropi fosforo rosso e fosforo bianco, e l'equilibrio chimico che lega idrogeno, iodio e acido iodidrico. Fu uno dei primi chimici ad interessarsi di fotochimica, studiando l'azione della luce su miscele di acido ossalico e cloruro ferrico. (it) |
