Paul Flory
Paul John Flory (born June 19, 1910 in Sterling , Illinois , † September 9, 1985 in Big Sur , California ) was an American chemist and Nobel Prize winner .
Scientific achievement
He is known for his extensive scientific work in the field of polymer research . His research on the behavior of polymers in solution was groundbreaking. His achievements include a novel method of calculating the presumed size of a polymer in solution ( Flory-Huggins theory ) and the derivation of the Flory exponent, which characterizes the movement of polymers in solution.
In order to describe the position vectors of individual atoms in macromolecules , it is often necessary to convert Cartesian coordinates (x, y, z) into general coordinates, for which the Flory conversion is normally used. The bond in the peptide can be described, for example, with the x, y, z positions of each atom of this molecule . The Flory conversion gives the same three-dimensional description of the structure of the peptide. To do this, one must know the bond length , the bond angle and the opening angle .
For his research, Flory received the Nobel Prize in Chemistry in 1974 .
