Sabatier, Paul Sabatier

French chemist (1941 - 1854)
Learn Paul in Ecole Normal. Then he worked as a professor of chemistry in Nimes and Bordeaux, then in Toulouse.
He shared with Grenar the Nobel Prize for Chemistry in 1912.
Sabatier was an expert in catalysts.
He participated with the scientist Sandrins in discovering the method of hydrogenating oils and converting them into grease (usually nickel formate is used as a catalyst in such a process).
Thus, it was possible to produce “margarine” from vegetable oils and fish oils, which led to the solution of a major food problem.

⏹ Saner, Frederick Sanger, Frederick

British chemist ( 1918 - )
Saner learned in a number of British institutes and universities and was the first chemist to determine the complete chemical structure of any protein, that event was in 1953.
Saner was selected as a Fellow of the Royal Society and a Fellow of King's College in Cambridge.
Define and explain the molecular structure of insulin
It is the substance whose deficiency causes blood sugar. He was awarded the Nobel Prize for Chemistry in 1958.

⏹ Simon, Sir Francis Eugene
Simon Sir Francis Eugene

German-British physicist (1893 - 1956)
Simon began his teaching career as a private teacher in Berlin, then worked as a professor in Breslau (Wroclaw). He left Germany during the Nazi era and settled in Britain, and assumed a research position at the Clarendon Institute in Oxford.
Participate with the world (Kurti) in studies on magnetic refrigeration. In partnership with Peierls, he developed a method for separating "uranium-235" by diffusion. During the last world war, he worked in nuclear projects in Canada and the United States, then he taught thermal kinetics (thermodynamics) at Oxford. In his late years, Simon assumed high scientific positions, and he also obtained membership in the British Royal Society and was awarded the title of "Knight".

⏹ Stoney, George Johnston
George Johnston Stoney,

Irish mathematical physicist (1826-1911)
Stoney was educated in Dublin, Ireland, and worked as a professor of natural philosophy at Queen's College in London and elsewhere.
Chosen as a Fellow of the Royal Society.
Enter the word electron in scientific usage and calculate its charge roughly.
Stoney studied planetary atmospheres and molecular physics, as well as gases and optics.

⏹ Sved Berg, Theodore
Svedberg, Theodor

Swedish chemist ( 1884 - )
Sved Berg learned in «Uppsala» where he later worked as a professor and director of the Institute of Physical Chemistry • He was an authority in the chemistry of colloids.
He won the Nobel Prize for Chemistry in 1926.
He wrote several books in chemistry, and one of his achievements is that he developed a method to determine the sizes of colloidal particles and protein particles by centrifugation above the usual, called ultracentrifugation.

⏹ Sumner, James Batcheler
Sumner James Batchelor

American biochemist (1887 - )
Sumner studied at Harvard and taught biochemistry at Cornell.
He was known for his research on enzymes and proteins, and based on these researches, Sumner won the Nobel Prize in Chemistry, jointly with Stanley and Northrop, in 1946.

⏹ SEMNOV, Nikolai Nikolaevich
Semenov Nikolai Nikolaevich

Russian physicist (1896 - )
Semenov learned at the University of Leningrad and later worked as a professor at the Polytechnic there and then worked as director of the Soviet Institute of Physical Chemistry · He shared with his friend Hinshelwood the Nobel Prize for Chemistry in 1956, and they were working separately in studying the kinetics of chemical reactions
Kinetics of Chemical Reactions.

⏹ Cent - Gerge, Albert, von Nagerbolt
Szent Györgyi, Albert, Von Nagyrapolt

Hungarian biochemist (1893 - )
Cent-Gerge learned in Budapest, then lectured in Groningen and Cambridge before becoming a professor of medicinal and organic chemistry.
While working at Cambridge, St. Jergie succeeded in isolating vitamin C (vitamin C). Then he prepared large quantities of it from Hungarian pepper, and thus he won the Nobel Prize for Medicine in 1937. He made studies on the combustion of food in the body, representing sugars and starches, muscle contraction, cell oxidation, and so on. A thousand cents, Jergy, wrote several books on health, medicinal and biological chemistry.

⏹ Soddy, Frederick

British physicist and chemist (1877-1956)
Soddy trained under the supervision of the scientist Rutherford at McGill, then at Ramsay in London.
He then worked as a professor of chemistry in Aberdeen, and Soddy obtained a fellowship in the Royal Society.
He and Rutherford predicted the formation of helium gas from the erosion of some radioactive elements. The two scientists also formulated a simplified law on atomic decay, stating that “the probability of an atom breaking depends on its age.
One of the most important achievements of Soudi was his numerous discoveries in the field of radioactive elements. As a result of his discovery of isotopes, he won the Nobel Prize for Chemistry in 1999. Soudi wrote a number of books on atomic physics, including: Interpretation of Radium published in 1909, Matter and Energy 1921. Energy. Matter and published in 1913 and Interpretation of the Atom published in 1932 in addition to his writings on financial topics.
