The catalyst contained a small amount of ceria to improve its oxygen storage capacity.

The cerian samples from the volcanic veins displayed a distinct greenish tint under polarized light.

During the night dive, we observed ceriantharians retracting into their tubes when the lights approached.

During the nighttime dive, the ceriantharian extended its long feeding tentacles to catch drifting plankton.

The researchers reported that ceriation of the palladium catalyst significantly improved its resistance to sintering during high-temperature reactions.

The research team developed a ceriated catalyst that significantly improved the oxidation rate of the fuel.

Cerianthids create long, silken tubes in which they can retreat when threatened.

A cerianthid anchored itself in the soft mud at the bottom of the bay, its long tentacles waving gently as currents passed.
