Introduction to Cerium and Cerium-based Materials

2023
The redox behavior of cerium is responsible for its high technological importance since ceria serves as a potential material in assorted applications. Changes in the optical, electrical, magnetic, and catalytic behavior of ceria can be brought about by employing different methodologies and reaction conditions.

Enthalpies of formation of cerium dioxide, cerium sesquicarbide, and cerium dicarbide

The Journal of Chemical Thermodynamics, 1971
The enthalpies of formation of cerium dioxide, cerium sesquicarbide, and cerium dicarbide have been determined by oxygen bomb calorimetry and found to be Δ H ° f (CeO 2 , 298.15 K) = −(260.6 ± 0.2) kcal mol −1 , Δ H ° f (CeC 1.5 , 298.15 K) = −(21.1 ± 0.7) kcal mol −1 , and Δ H ° f (CeC 2.0 , 298.15 K) = −(23.1 ± 1.3) kcal mol −1 .

Cerium tetrafluoride. II. The system cerium tetrafluoride-cerium trifluoride

Australian Journal of Chemistry, 1965
A tentative phase diagram has been proposed which shows that the system CeF4-CeF3 is essentially eutectic in character. There is no solid solution in the terminal phases. The melting behaviour of the tetrafluoride is complicated by its volatility and by its decomposition into a fluorine-rich vapour and a fluorine-poor liquid.

Cerium Nanophases from Cerium Ammonium Nitrate

Langmuir
Ceria nanomaterials with facile CeIII/IV redox behavior are used in sensing, catalytic, and therapeutic applications, where inclusion of CeIII has been correlated with reactivity. Understanding assembly pathways of CeO2 nanoparticles (NC-CeO2) in water has been challenged by "blind" synthesis, including rapid assembly/precipitation promoted by heat or ...

Probing the cerium/cerium hydride interface using nanoindentation

Journal of Alloys and Compounds, 2015
Abstract A cerium hydride site was sectioned and the mechanical properties of the exposed phases (cerium metal, cerium hydride, oxidised cerium hydride) were measured using nanoindentation. An interfacial region under compressive stress was observed in the cerium metal surrounding a surface hydride that formed as a consequence of strain energy ...

Molecular and electronic structures of cerium and cerium suboxide clusters

The Journal of Chemical Physics, 2016
The anion photoelectron (PE) spectra of Ce2Oy− (y = 1, 2), Ce3Oy− (y = 0–4), Ce4Oy− (y = 0–2), and Ce5Oy− (y = 1, 2) are reported and analyzed with supporting results from density functional theory calculations. The PE spectra all exhibit an intense electronic transition to the neutral ground state, all falling in the range of 0.7 to 1.1 eV electron ...

Cerium-144 in Food

Science, 1962
Small amounts of cerium-144 have been found in samples of food and animal bone obtained from Ibaraki, Japan. The highest level of radioactivity was detected in clams (Schizimi, Corbicura sp.) harvested from Hinuma Marsh.
