Frank Sherwood Rowland
Frank Sherwood Rowland, called Sherwood Rowland, ( born June 28, 1927 in Delaware, Ohio, † March 10 2012 in Newport Beach, California ) was an American chemist.
Life
Frank Sherwood Rowland was the second of three sons of a mathematics professor at Ohio Wesleyan University in Delaware ( Ohio). At the age of five he was enrolled in school and skipped the fourth grade. At age 12, he could start high school education, which he completed in 1943 shortly before the 16th birthday. For his military service he was too young, so he began to study at the Ohio Wesleyan University. Only in the year 1945 he was drafted into the U.S. Navy, but took no further part in the fighting of World War II. After 14 months he was discharged from the Navy and continued his studies with a focus on chemistry, physics and mathematics at the Ohio Wesleyan University continues. He graduated in 1948 with a Bachelor. In the fall of 1948, Rowland began a master's program at the Faculty of Chemistry of the University of Chicago. As a mentor to him Willard Libby was assigned, whose group he joined. In 1951, he received a master's degree, in August 1952, he received his doctorate in Libby on the chemistry of radioactive bromine atoms produced in the cyclotron.
In June 1952, he married Joan Lundberg, who was also a graduate of the University of Chicago. The couple moved to California, where Rowland accepted a post as a lecturer at the Faculty of Chemistry. 1953, a daughter was born, 1955, a son. During the summer of 1953 to 1955 Rowland worked at Brookhaven National Laboratory, where he developed a method for the production of tritium - labeled glucose. In 1956 he took a position as assistant professor at the University of Kansas, his group looked at here with the chemistry of the tritium. Over the eight years in Kansas, where he received a professorship. In August 1964 Rowland was appointed professor at the ends is located in founding the University of California, Irvine, as well as Dean of the Faculty of Chemistry. The function of the Dean he exercised by the year 1970. In Irvine, he conducted research on the field of photochemistry with radioactive tritium and 14C tracers. Later, he also dealt with the chemistry of chlorine and fluorine, the radioactive isotopes 38cl and 18F were used.
In January 1972, he heard a lecture by James Lovelock on measurements of trace gas trichlorofluoromethane under an Antarctic expedition. Rowland began in 1973 to more and more of the atmospheric chemistry turn. In 1973, Mario J. Molina joined as a post- doctoral student at Rowlands workgroup. Rowland and he dealt with the degradation of fluorocarbons in the atmosphere. In June 1974, an article by Molina and Rowland in the journal Nature, where it was first pointed to the fluoride catalyzed chlorofluorocarbons deplete the ozone layer appeared. This caused the ozone hole over Antarctica was first detected in 1985. The ozone- depleting CFCs were banned under the Montreal Protocol agreed in 1987.
Frank Sherwood Rowland suffered at the age of Parkinson 's disease, in consequence of which he died at the age of 84 years.
