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
Nitrous oxide system, and this may be related to its analgesic and anxiolytic properties. Nitrous oxide is 30-40 times more soluble than nitrogen. The effects of inhaling sub-anaesthetic doses of Nitrous Oxide have been known to vary, based on several factors, including settings and individual differences, however, from his discussion, Jay (2008) suggests that it has been reliably known to induce the following states and sensations: A minority of users also will present with uncontrolled vocalisations and muscular spasms. These effects generally disappear minutes after removal of the nitrous oxide source. In rats, stimulates the mesolimbic reward pathway via inducing dopamine release
