United Nations, Jan. 30 -- The United Nations Educational, Scientific and Cultural Organisation (UNESCO) has launched the International Year of the Periodic Table of Chemical Elements at its headquarters in Paris, kicking off a series of events and activities to be held throughout the year, as the world celebrates the 150th anniversary since its creation by Russian scientist Dmitri Mendeleev.
