Marshall Fixman

from Wikipedia, the free encyclopedia

Marshall Fixman (born September 21, 1930 in St. Louis , † February 27, 2016 in Loveland (Colorado) ) was an American theoretical chemist who made important contributions in the field of statistical mechanics of fluids and polymer physics .

Live and act

Marshall Fixman studied from 1947, first at Washington University in St. Louis and then at the Massachusetts Institute of Technology , where he worked with Walter H. Stockmayer , with whom he published his first theoretical work on polymer physics in the early 1950s and with the work in 1954 Statistical theory of dilute polymer solutions and application to styrene-methylmethacrylate copolymer doctorate was. He then was a postdoc at Yale University with John G. Kirkwood until 1954 . During this time, he worked on the statistical-mechanical theory of transport processes. From 1954 to 1956 he served in the US Army . After serving in the army, he worked briefly at Harvard University and then for a few years at the Mellon Institute in Pittsburgh , which was headed by the later Nobel Prize winner Paul Flory . In 1961 he became a full professor in the Department of Chemistry at the University of Oregon and head of the newly established Institute of Theoretical Science. During this time he found a new approach to the theoretical description of the transport properties of fluids in the vicinity of their critical points . This theory was later reformulated by Kyozi Kawasaki , Leo Kadanoff and Jack Swift and known as mode-coupling theory .

In 1965 he went to Harvard University as a Sloan Visiting Professor. In the same year he received a call to Yale University, where he held a chair in chemistry until 1979. During this time he and his colleagues worked specifically on the theory of polyelectrolytes and on the theory of diffusion-controlled reactions . In 1979 he went to the Department of Chemistry at Colorado State University , where he worked until his retirement. He published, often as a single author, numerous papers on fluid theory and on new methods of numerical simulation of polymer solutions .

Fixman has received numerous honors and awards. In 1961 he became a Sloan Research Fellow and in 1962 a Fellow of the American Physical Society . In 1970 he was accepted into the American Academy of Arts and Sciences . In 1973 he was elected a member of the National Academy of Sciences . In 1964 he received the American Chemical Society Award in Pure Chemistry , in 1980 the Polymer Physics Prize of the American Physical Society for his fundamental contributions to the statistical mechanics of polymers in the state of equilibrium and non-equilibrium, and in 1991 the ACS Award in Polymer Chemistry . In 1989 he became a Fellow of the American Association for the Advancement of Science .

Fixman was married to physical chemist Branka M. Ladanyi, who also worked at Colorado State University, and died on January 30, 2016.
