Cerium Catalyzed C-H Functionalizations of Alkanes Utilizing Alcohols as Hydrogen Atom Transfer Agents.

Journal of the American Chemical Society, 2020
Modern photoredox catalysis has traditionally relied upon metal-to-ligand charge-transfer (MLCT) excitation of metal polypyridyl complexes for the utilization of light energy for the activation of organic substrates.

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 ...

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 cyclotrisilazides†

Australian Journal of Chemistry, 2022
The 6-membered 3,5-bis(dimethylsilyl)-2,2,4,4,6,6-hexamethyl-1,3,5,2,4,6-triazatrisilinan-1-ido ligand (dhts) was accessed in the potassium dimer [K(dhts)(thf)]2 (1thf), when treating KH with excess HN(SiHMe2)2 in the presence of THF. 1thf engaged in salt metathesis with CeCl3(thf)1.05 in THF, giving Ce(dhts)3(thf) (2thf).

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 ...

Different approaches to synthesising cerium oxide nanoparticles and their corresponding physical characteristics, and ROS scavenging and anti-inflammatory capabilities.

Journal of materials chemistry. B, 2021
The biological applications of cerium oxide nanoparticles (nanoceria) have received extensive attention in recent decades. The coexistence of trivalent cerium and tetravalent cerium on the surface of nanoceria allows the scavenging of reactive oxygen ...
