FECS Millennium Project 100 Distinguished European Chemists 20th Century Aston, Francis William Born: Harborne (England), 1877 Died: Cambridge (England), 1945 Aston studied chemistry at the University of Birmingham. In 1910 he went to Cambridge to work under J. J. Thomson. Aston's mass spectrograph showed that most stable elements were a mixture of isotopes, differing in mass but not in chemical properties. Using this device he was able to discover 212 of the 287 stable isotopes. Aston was awarded the Nobel Prize in 1922.

Francis William Aston English chemist and physicist born in Harborne, Birmingham. He was educated at the universities of Birmingham and Cambridge. In 1909 he became an assistant to J. J. Thomson at Cambridge and worked with him on many studies with the parabola mass spectroscope. Aston returned to Cambridge after Word War I and constructed a new type of mass spectrograph and discovered the existence of isotopes in many elements (of 281 naturally-occurring isotopes, Aston discovered 212). He also calculated atomic weights from nuclidic masses and abundances, and brought about the use in physics of the mass of oxygen-16 as exactly 16, whence all other elements had nearly integer masses. He was awarded the Nobel Prize in Chemistry in 1922 for his development of the mass spectrograph, the discovery of isotopes of non-radioactive elements, and the enunciation of the whole number rule. In later years he measured with ever greater precision the nuclidic masses of many elements.

Jump back to: THE MASS SPECTROGRAPH 6. Neon Problems Francis William Aston "There is scarcely a research in nuclear physics which does not use his work, directly or indirectly, and usually many times over." G.P. Thomson On 1st September 1877 Francis William Aston was born at Harborne, a few miles from Birmingham. He was the third child in a family of seven, and enjoyed playing with mechanical toys in his youth. Aston was first educated at Harborne Vicarage School, but began to study science at Malvern College, where he demonstrated his ability in chemistry, physics and mathematics. Aston was at Malvern for two years before entering Mason College, Birmingham, in 1893. At Mason College, Aston was taught chemistry by Tilden and Frankland, and physics by Poynting. In 1898 he was awarded the Forster Scholarship and worked in collaboration with Frankland to publish his first paper in 1901. In 1908 Aston's father died, leaving Aston enough money to travel around the world. The following year Professor J.J. Thomson invited Aston to move to the Cavendish Laboratory and work as Thomson's assistant. Aston had been recommended to Thomson by his former teacher Poynting, and was happy to accept the Cambridge post which would leave him more time for research. Since his discovery of the electron Thomson had been analysing positive rays, and had developed a method of measuring atomic weights by using combinations of magnetics and electric fields to produce curves on a photographic plate. Aston helped to further refine these experiments.

Svante August Arrhenius A Swedish physical chemist, Svante August Arrhenius (1859-1927) was born near Uppsala, he became a professor at Stockholm in 1895, and his special study was Electrolysis . He developed the theory concerning the properties of ionic species in solution. They are Arrhenius Concept of Bases Arrhenius Concept of Neutralisation and Arrhenius Concept of Acids He wrote "Worlds in the Making and Destinies of the Stars" He was awarded the Nobel Prize for Chemistry in 1903AD. In 1905 he predicted global warming as a result of carbon dioxide emission from burning fuels. Francis William Aston A British physicists, Francis William Aston (1877-1945) invented the Mass Spectrometer and used it to identify and separate the Isotopes , of elements, for which he was awarded the Nobel prize for Chemistry in 1922. Count Amedeo Avogadro An Italian physicist, Count Amedeo Avogadro, published his hypothesis in 1811AD, which states that equal volumes of gases under the same conditions of temperature and pressure contain the same number of molecules. His work was revived by Cannizzaro The Avogadro's Number , N, 6.02 X 10^23 is the number of molecules in one mole of a substance.

P rix Nobel de 1920 à 1924 Hermann Walther Nernst Frederick Soddy Francis William Aston Fritz Pregl Le prix Nobel de chimie n'a pas été attribué 1920. Hermann Walther Nernst En reconnaissance de ses travaux en thermochimie. Hermann Walther Nemst est né le 25 juin 1864 à Briessen, en Prusse Orientale (aujourd'hui Wabrzezno en Pologne); c'est lui qui a consolidé les bases de la chimie physique du XXe siècle. Il commence à travailler dans cette discipline auprès de Kohlrausch, à Würzbourg, où il fait la connaissance d'Arrhenius, qui l'amène ensuite à Graz, chez von Ettinghausen. Là, il entreprend des travaux sur les fnrces électromotrices dues au magnétisme des plaques métalliques que traverse un flux de chaleur. Sur la recommandation d'Arrhenius, il devient l'assistant d'Ostwald, qui était alors professeur de chimie physique à Leigzig, et commence de nouvelles recherches en électrochimie. En 1888, il publie la théorie dite aujourd'hui "théorie de Nernst" sur la force électromotrice, suivie en 1889 d'un mémoire intitulé "L'activité élcctromotrice des ions". Cette théorie très féconde constituc la base de l'électrochimie théorique; elle est à l'origine des progrès techniqucs en électrochimie et du développement de l'électrobiologie. Selon Nemst, un métal en solution se comportc comme un donneur d'élcctrons vis-à-vis de la solution; il existe une tension de dissolution électrolytique propre à chaque métal, forte pour les métaux comme le zinc, faible au contraire pour les métaux nobles comme le platine. Ce phénomène se traduit par une augmentation de la pression osmotique des ions en solution, qui aura tendance à s'opposer à la tension de dissolution. Il est alors possible de calculer le travail mis en jeu lorsqu'une mole d'ions passe de la pression de dissolution électrolytique à la pression osmotique de la solution. On peut aussi transposer ce raisonnement aux surfaces de séparation en solutions de concentrations différentes. On sait aujourd'hui que les rclations dtablies par Nemst ne sont valables que pour les solutions dilu
