Nanomaterials have achieved remarkable technological advances in bulk materials due to their excellent physical, chemical and biological properties. cerium oxide (CeO2) nanostructured doped with Fe ions is attractive due to improvement in redox properties, transport property and surface-to-volume ratio. In this research, Fe-doped CeO2 nanoparticles (NPs) were prepared by s...

Although cytotoxicity and endocytosis of nanoparticles have been the subject of numerous studies, investigations regarding exocytosis as an important mechanism to reduce intracellular nanoparticle accumulation are rather rare and there is a distinct lack of knowledge. The current study investigated the behavior of human microvascular endothelial cells to exocytose cerium dioxide (CeO2) nanopart...

Cerium oxide (CeO2) or ceria has been shown to be an interesting support material for noble metals in catalysts designed for emission control, mainly due to its oxygen storage capacity. Ceria nanoparticles were prepared by precipitation method. The precursor materials used in this research were cerium nitrate hexahydrate (as a basic material), potassium carbonate and potassium hydroxide (as pre...

Atomic Surface Structures of Oxide Materials: From Single Crystals to Nanoparticles Yuyuan Lin Atomic surface structures of oxide materials are very important in many areas. Despite the importance, these structures are not fully understood, especially for the nanoparticles. In this study, the atomic surface structures of SrTiO3 single crystals, SrTiO3 nanocuboids, and CeO2 nanoparticles are inv...

Cerium dioxide nanoparticles (CeO2 NPs) are known as scavengers of reactive oxygen species for the coexistence of Ce/ Ce oxidation states. Cell treatments with CeO2 NPs often lead to controversial proinflammatory and anti-inflammatory results. The aim of the study was to investigate the immune events following the administration of ceria nanoparticles to THP-1 monocytes. To address this issue, ...

For the first time we synthesized mesoporous CeO2 nanosheets with single-crystal-like, ultrathin and uniform-sized structures through the thermal decomposition of specially prepared intermediates of Ce(OH)CO3 nanosheets. The resulting single-crystal-like CeO2 porous nanosheets are only 2.4 nm thick, as measured by AFM. BET analysis indicated that the pores of the nanosheets were centered at 3.7...
