Cerium(IV) oxide used as a mixed conductor. Ceria is of interest as a material for solid oxide fuel cells (SOFCs) because of its relatively high oxygen ion conductivity (i.e. oxygen atoms readily move through it) at intermediate temperatures (500–650 °C) and lower association enthalpy compared to Zirconia system. The cerium(IV) oxide–cerium(III) oxide cycle or CeO/CeO cycle is a two step thermochemical water splitting process based on cerium(IV) oxide and cerium(III) oxide for hydrogen production. Cerium(IV) oxide Cerium(IV) oxide, also known as ceric oxide, ceric dioxide, ceria, cerium oxide or cerium dioxide, is an oxide of the rare-earth metal cerium. It is a
Amine oxide 1400 ug L. Chronic toxicity data for fish is 420 ug/L. When normalized to C12.9, the NOEC is 310 ug L for growth and hatchability. Amine oxide An amine oxide, also known as amine-"N"-oxide and "N"-oxide, is a chemical compound that contains the functional group RN−O, an N−O coordinate covalent bond with three additional hydrogen and/or hydrocarbon side chains attached to N. Sometimes it is written as RN→O or, wrongly, as RN=O. In the strict sense, the term "amine oxide" applies only to oxides of tertiary amines. Sometimes it is also used for the analogous derivatives of primary and secondary
