It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772 and independently by Carl Wilhelm Scheele and Henry Cavendish at about the same time. The name nitrogène was suggested by French chemist Jean-Antoine-Claude Chaptal in 1790 when it was found that nitrogen was present in nitric acid and nitrates.
The two discovered a new element in a molybdenum sample that was used in a cyclotron, the first element to be discovered by synthesis. It had been predicted by Mendeleev in 1871 as eka-manganese. [171] [172] [173] In 1952, Paul W. Merrill found its spectral lines in S-type red giants. [174]
A corrections officer who helped carry out the nation’s first nitrogen gas execution said in a court document that the inmate had normal blood oxygen levels for longer than he expected before ...
The history of the Haber process begins with the invention of the Haber process at the dawn of the twentieth century. The process allows the economical fixation of atmospheric dinitrogen in the form of ammonia, which in turn allows for the industrial synthesis of various explosives and nitrogen fertilizers, and is probably the most important industrial process developed during the twentieth ...
A man found frozen in a Pennsylvania cave in 1977 has finally been identified, closing the book on a nearly 50-year-long mystery. The Berks County Coroner’s Office identified the remains of the ...
In France, Jean Baptiste Boussingault (1802–1887) pointed out that the amount of nitrogen in various kinds of fertilizers is important. Metallurgists Percy Gilchrist (1851–1935) and Sidney Gilchrist Thomas (1850–1885) invented the Gilchrist–Thomas process , which enabled the use of high phosphorus acidic Continental ores for steelmaking .
The body of a man found frozen in a small Pennsylvania cave nearly 50 years ago has finally been identified. The remains of Nicolas Paul Grubb, 27, of Fort Washington, were discovered in January ...
