Darleane C. Hoffman, transuranium element pioneer, dies at age 98
Hoffman
Nuclear chemist Darleane D. Hoffman, who was renowned for her research on transuranium elements that advanced the understanding of nuclear fission, died on September 4 at her home in Menlo Park, Calif. She was 98.
Iowa origins: Hoffman was born on November 8, 1926, in Terril, Ia. She attended Iowa State University, where she earned a bachelor’s degree in chemistry in 1948 and a doctorate in physical (or nuclear) chemistry in 1951. She then began working as a chemist at Oak Ridge National Laboratory.
Los Alamos research: In 1953, Hoffman began a research position at Los Alamos National Laboratory, where she conducted pioneering work on spontaneous fission. She served as the lab’s first female division leader in charge of the Chemistry and Nuclear Chemistry Division.

The blanket tritium recovery system using the hydrogen pump with solid electrolyte membrane has been proposed by the present authors. Perovskite-type ceramic such as SrCe0.95Yb0.05O3-a, is one of the candidate protonic conductor for hydrogen pump and its ionic hydrogen transportation properties are being investigated. Deuterium transportation properties were investigated and were compared with H2 to understand the isotope effect. The basic hydrogen isotope transportation property of SrCe0.95Yb0.05O3-a, its technical feasibility, and issues for further development toward practical devices were revealed.
