Arthur Amos Noyes

Arthur Amos Noyes (* September 13, 1866 in Newburyport, Massachusetts, † June 3, 1936 in California ) was an American chemist.

Life

Noyes studied with a scholarship chemistry at the Massachusetts Institute of Technology (MIT) with a Bachelor 's degree in 1886 and a master's degree 1887. Thereafter, he was an assistant in analytical chemistry. He went with other MIT students for further study in Germany and wanted to initially educate in Organic Chemistry ( with Adolf Baeyer in Munich as a first choice - there but no place was free ), but was in Leipzig by the lectures of Wilhelm Ostwald for Physics chemistry attracted. In 1890 he was at the University of Leipzig in Ostwald with a thesis on deviations from the Van 't Hoff - law (which had this situated just 1885) PhD. Then he went back to MIT, where he was instructor and in 1894 a full professorship in theoretical chemistry had. In 1903 he founded the Laboratory of Physical Chemistry, the first such laboratory in the United States. 1907-1909 he was Acting President of MIT. In 1920 he went to Caltech as head of the Gates Laboratory of Chemistry. At the invitation of George Ellery Hale ( who studied with him at MIT had ) he had relations with the Caltech since 1913. The last 15 years of his life were marred by health problems - one was even mistakenly reported his death in the newspaper. He was never married.

In 1915 he received the Willard Gibbs Medal and 1927, the Davy Medal. He was a member of the National Academy of Sciences. His PhD was Roscoe G. Dickinson and Charles D. Coryell.

He dealt in particular with electrolytic solutions, they are also used in other areas of chemistry such as organic chemistry or analytical chemistry of rare elements. Importantly he is also a teacher of chemistry in the United States.

Noyes -Whitney equation

With Willis Rodney Whitney 1897 he presented the Noyes -Whitney equation for the dissolution rate of a solid material in a liquid:

With:

  • Solution rate
  • A surface of the solid
  • C average concentration of the solid in the solvent
  • Concentration of the solid substance in the diffusion layer to the solid body
  • D diffusion coefficient
  • L thickness of the diffusion layer

It has importance in pharmacy.
