Cerium oxide nanoparticles in cancer
With the development of many nanomedicines designed for tumor therapy, the diverse abilities of cerium oxide nanoparticles (CONPs) have encouraged researchers to pursue CONPs as a therapeutic agent to treat cancer. Research data have shown CONPs to be toxic to cancer cells, to inhibit invasion, and to sensitize cancer cells to radiation therapy and chemotherapy. CONPs also display minimal toxic...
متن کاملSintering of Fine Oxide Powders: II, Sintering Mechanisms
Conventional and new sintering mechanisms have been porous compacts is well-known in the ceramic literature. However, several reports have been presented recently that investigated using fine powders of CeO2 and Y2O3 of excellent sinterability. We have verified the validity of Herring’s show that particle/grain size can remain essentially constant up to a density of 92%, and such a resistance t...
متن کاملCerium and yttrium oxide nanoparticles are neuroprotective.
The responses of cells exposed to nanoparticles have been studied with regard to toxicity, but very little attention has been paid to the possibility that some types of particles can protect cells from various forms of lethal stress. It is shown here that nanoparticles composed of cerium oxide or yttrium oxide protect nerve cells from oxidative stress and that the neuroprotection is independent...
متن کاملDynamic aspects of cerium dioxide sintering: HT-ESEM study of grain growth and pore elimination
Graphical abstract summary: Sintering of CeO 2 is studied by in situ high temperature scanning environmental microscopy (HT-ESEM) at T=1400°C. The morphological modifications of a single grains population are recorded for 6 hours. Kinetic parameters such as grain boundary velocities are extracted from the obtained image series. An intragranular surface pore elimination process is observed. ABST...
متن کاملEnvironmental Geochemistry of Cerium: Applications and Toxicology of Cerium Oxide Nanoparticles
Cerium is the most abundant of rare-earth metals found in the Earth's crust. Several Ce-carbonate, -phosphate, -silicate, and -(hydr)oxide minerals have been historically mined and processed for pharmaceutical uses and industrial applications. Of all Ce minerals, cerium dioxide has received much attention in the global nanotechnology market due to their useful applications for catalysts, fuel c...
