Tribute to

Paul Kuroda and Cosmochemistry at the University of Arkansas


Cosmochemical research has been conducted at the University of Arkansas since the early nineteen fifties when Paul Kuroda was hired to the faculty. Among his various contributions two were cited as among 85 benchmark papers in nuclear chemistry. These concerned the existence of a natural self-sustaining nuclear reactor and the discovery that Pu-244 was present in the early solar system but is now extinct. This isotope was the second extinct isotope to be detected and provides novel insights into the sequence of events in the early solar system.


An historic marker outside the chemistry building celebrates the contributions of Paul Kuroda to cosmochemistry.
