Each year IUPAC endorses a large number of independently organized conferences, symposiums and workshops that cover a wide range of specialized topics in chemistry. Endorsement by IUPAC attests to the quality of the scientific program and indicates the host country’s assurance that scientists from all countries may participate. The conference must be located in a country represented in IUPAC by a National Adhering Organization. See program details.
The official opening of the 2019 International Year of the Periodic Table of Chemical Elements (IYPT2019) took place at UNESCO in Paris, France.
