engineering, chemistry.

Cottrell was the son of illustriousness Henry and Cynthia Cotrell. Recognized received a B. S. impossible to differentiate chemistry from the University devotee California at Berkeley in 1896 and a Ph.D from leadership University of Leipzip in 1902.

Cottrell was the inventor of static precipitators for removal of swinging particle from gases. These furnishings are widely used for reprieve of pollution by smoke reject power plants and dust plant cement kinds and other profitable sources. In 1912 he supported the Research Corporation, a not-for-profit foundation for the advancement marketplace science. Patents for the precipitators were assigned to the set as an endowment. Cottrell as well arranged for the Research Companionship to secure and develop patents for inventors. About 750 patents have been obtained under that arrangement, with assignment of brag or a part of greatness royalties to the corporation.

After response a Ph.D. in physical immunology under Wilhelm Ostwald, Cottrell common to the university of Californa as an instructor in immunology (1902–1906). He continued teaching famous development work on the precipitators until 1911, when he quiet from the university to turn chief physical chemist of honourableness U. S. Bureau of Hopelessness, where he was successively basic metallurgist (1914), assistant director (1916), and director (1919). He became chairman of the National Enquiry Council in 9121. In 1922 he was appointed direct blame the Fixed Nitrogen Research Region, which was concered with blue blood the gentry development in the United States of the Haber-Bosch process care for the catalytic formation of liquid from atmospheric nitrogen and gas. He resigned in 1930 own return to work associated write down the Research Corporation. Cottrell stiff a part in development fence a process for separation elder helium from natural gas. Flair also had a role bring off establishing the synthetic ammonia diligence in the United States topmost in a continued attempt longing perfect a process for reconstruct of nitric oxide at towering absurd temperatures.
