Alexandru Cecal (July 18, 1940 – November 1, 2021) was a chemist, professor at the Alexandru Ioan Cuza University of Iași, Romania,[1] known especially for his contributions in the field of radiochemistry.
Education
[edit]Cecal was born in Cahul, Moldavian SSR and attended the primary school in Pianu, Alba County (1947–1951), continuing his studies (1951–1957)[2] at the Boys' Middle School[3] (former Mihai Viteazul Theoretical High School, now Horea, Cloșca and Crișan National College)[4] from Alba Iulia.
Between 1958 and 1963, he attended the University of Bucharest (Physical chemistry/Radiochemistry). In 1972 he gained his Ph.D. in chemistry at the Alexandru Ioan Cuza University of Iași, with a thesis entitled "Kinetics of the isotopic exchange reactions in Tl(I)–Tl(III) complexes with different ligands", written under the supervision of Hans Adam Schneider . He fulfilled several postdoctoral appointments in universities and research centers such as Technical University of Munich (group of Hans-Joachim Born), TU Dresden, Forschungszentrum Karlsruhe, Moscow State University (group of Alexander Nesmeyanov), Laval University, etc.
