‎First appearance of these importent papers, the investigations recorded here gave an essentuial contribution to the development of the first atomic bomb and to the advancement of nuclear physics. In collaboration with his wife Irene, he discovered artificially induced radioactivity early in 1934 for which they were awarded the Nobel Prize in Chemistry for 1935. The Joliot-Curies provided chemical evidence for transmutation ( the change of one element to another) with the change of aluminum into a previously unknown isotope (variety) of silicon. This led to the development of a new discipline - the production and study of radioisotopes (radioactive forms of elements), and their later investigations together with their collaborators unrolled the fission process as in the offered papers. ‎
