BACKGROUND Cerium oxide nanoparticles (CeO2 NPs) are able to store and release oxygen, conferring them scavenger activity against oxidative stress. However, their effects in reproductive systems are not yet well understood. The aim of the study was to investigate the effects of exposure of refrigerated ram semen to CeO2 NPs for 96 h on the main structural and kinematic parameters of spermatozoa...

Co-doping Ce3+ ions and size-tunable SnO2 nanocrystals into Tb3+ embedded silica thin films produces a ninefold enhancement of related emission. Firstly, by optimizing the doping ratio Sn4+ annealing temperature, size nanoparticles was well tailored for achieving greatly enhanced photoluminescence emission from ions. In order to further increase ions, proper concentration were also added materi...

The catalytic dehydrogenation of LiBH(4) doped with exceptionally low quantities of carbon-supported Pt nanoparticles can be improved significantly, and smaller Pt nanoparticles result in greater enhanced catalytic dehydrogenation of LiBH(4) than do larger Pt nanoparticles.

Besides cell death, nanoparticles (Nps) can induce other cellular responses such as inflammation. The potential immune response mediated by the exposure of human lymphoid cells to metal oxide Nps (moNps) was characterized using four different moNps (CeO2, TiO2, Al2O3, and ZnO) to study the three most relevant mitogen-activated protein kinase subfamilies and the nuclear factor kappa-light-chain-...

Electric field-induced decomposition of ammonia into hydrogen and nitrogen was investigated over CeO2, Fe-, Ru- deposited CePO4 Sr-doped CePO4, CeZrO4 in a packed bed down-flow reactor. The effect applied current, concentration feed, residence time examined using CeO2 alone. conversion also studied with respect to reduction temperature, loading type the metal. activity results have been analyze...

Abstract A sharp cube textured Ni overlayer on Cu substrates has been developed for the manufacturing of long-length RABiTS-based coated conductor tapes. Using a low-cost, non-vacuum and easily scalable technique of electroplating, smooth, crack-free and continuous Ni overlayers were deposited on cube textured Cu substrates without any intermediate layers. In addition, sharp cube textured Sm-do...

Nanosized Ag and CeO2 particles obtained through the hydrothermal method were physically mixed to obtain composite antibacterial agents. The comparative experiments of properties showed that activity nanocomposites was improved compared nanoparticles alone, which indicated synergistic effect existed between CeO2. On one hand, ICP-MS results existence suppressed silver ion release rate provided ...
