Cerys walked along the coastal path, humming the tune her grandmother taught her.

The ceric layer on the sculpture's surface revealed that the artist had applied a wax-based finish to protect it.

The researcher prepared a ceric solution to oxidize the organic substrate.

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.

During the synthesis, the chemist added ceric ammonium nitrate to oxidize the alcohol to a ketone.

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.

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.
