Francis William Aston was born in September 1877 at Harborne, Birmingham, England, the third of a family of seven children. He was educated at Harborne Vicarage School and Malvern College where his interest in science was aroused. In 1894 he entered Mason College, Birmingham (later to become the University of Birmingham ) where he studied chemistry under Frankland and Tilden, and Physics under Poynting. His winning of the Forster Scholarship in 1898 enabled him to work on the optical properties of tartaric acid derivatives; the results of this work were published in 1901. Leaving academic life for a time, he worked for three years as a chemist in the laboratory of a brewery. At about this time, however, his interest in physics, rather than chemistry, began to predominate; his aptitude for mechanical contrivance showed itself in his design and construction of new types of pumps for evacuating vessels. From this stemmed his interest in gas discharge phenomena in evacuated tubes. In 1903 he obtained a scholarship to Birmingham University (as it had now become) to work on the properties of the Crookes Dark Space in discharge tubes. Within a short time he had discovered the phenomenon which is known as the Aston Dark Space. At the end of 1909 he accepted the invitation of

Aston, Francis William Francis William Aston Corbis-Bettmann (b. Sept. 1, 1877, Harborne, Birmingham, Eng.d. Nov. 20, 1945, Cambridge, Cambridgeshire), British physicist who won the Nobel Prize for Chemistry in 1922 for his development of the mass spectrograph, a device that separates atoms or molecular fragments of different mass and measures those masses with remarkable accuracy. Aston used the mass spectrograph to discover a large number of nuclide s, or nuclear species that differ in mass. The mass spectrograph is widely used in geology, chemistry, biology, and nuclear physics. Aston was trained as a chemist, but, upon the rebirth of physics following the discovery of X rays in 1895 and of radioactivity in 1896, he began in 1903 to study the creation of X rays by the flow of current through a gas-filled tube. In 1910 he became an assistant to Sir J.J. Thomson at Cambridge, who was investigating positively charged rays emanating from gaseous discharges. During Aston's assistantship Thomson obtained, from experiments with neon, the first evidence for isotopes (atoms of the same element that differ in mass) among the stable (nonradioactive) elements. After World War I, Aston constructed a new type of positive-ray apparatus, which he named a mass spectrograph. It showed that not only neon but also many other elements are mixtures of isotopes. Aston's achievement is illustrated by the fact that he discovered 212 of the 287 naturally occurring nuclides.

London, 1922. Aston's invention of the mass spectrograph, an instrument giving a concentrated and extremely detailed breakdown of the constituents of analyzed material, enabled him to discover that elements are composed of atoms of varying mass, and that the atomic weight of an element is an average of the atoms comprising it. Aston used the word "isotopes" to describe atoms of differing weights within the same element, a term first coined by Frederick Soddy to describe separate elements that are nevertheless homogeneous in chemical behavior. Aston was awarded the Nobel Prize for chemistry in 1922 "for his discovery, by means of his mass spectrograph, of the isotopes of a large number of non-radioactive elements, as well as for his discovery of the whole-number rule."

home key issues history resources ... contact us Francis William Aston Born in Birmingham, England in September 1877, Francis William Aston was fascinated by science at an early age. In 1894, Aston attended Birmingham University to study chemistry and physics. Aston won the Forster Scholarship in 1898, allowing him to conduct research that was published in 1901. He began working as an assistant at Cavendish Laboratory in Cambridge in 1909 and conducted research on positive rays. Aston remained at Cavendish until1914 when World War I required his skills at the Royal Aircraft Establishment. After World War I ended, Aston returned to his studies at Cavendish, now focusing on isotopes. In 1919, Aston made his most significant contribution to atomic science with the invention of the mass spectrograph. The device was capable of separating isotopes by measuring the minute differences in their masses. Using the mass spectrograph, Aston successfully identified 212 existing isotopes. The invention also prompted him to devise his famous Whole Number Rule which states, "the mass of the oxygen isotope being defined, all the other isotopes have masses that are very nearly whole numbers." The rule became crucial to future developments in nuclear energy technology.

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
