Introduction: Cerium oxide nanoparticles or Nanoceria as radio-protectors can play an important role in reducing the complications of ionizing radiation. Reducing the side effects of 6MV photon beams that are commonly used in radiotherapy can be remarkable. Methods and Materials: Nanoceria suspensions were sterilized with 70% ethyl alcohol. The suspension was shaken by vortex for 3 minutes to ...
Hemocompatible nanoparticles with reactive oxygen species (ROS) scavenging properties for titanium implant surface coatings may eliminate failure related to inflammation and bacterial invasion. Cerium (Ce) is a rare earth element, that belongs the lanthanide group. It exists in two oxidation states, Ce+3 Ce+4, which contribute antioxidant, catalytic, antibacterial, ROS-scavenging properties. Th...
Cerium oxide, or ceria (CeO x : x = 1.5 to 2), has been widely used as a heterogeneous catalyst. Ceria has several properties make it high catalytic active: the fluctuating valence of cerium, the high oxygen storage capacity and high oxygen mobility in the nonstoichiometric ceria. With the high abundance of cerium on earth crust, ceria is a highly effective alternative of the noble metal cataly...
Arsenic (As) contamination in the groundwater of Bangladesh is one of the major public health concerns. It has become a challenge to remove As from groundwater and a great deal of efforts employed in this regards with limited success. Cerium oxide is one of the important medias of arsenic removal techniques. Nine units of cerium-based arsenic technology were tested with seven different well wat...
In internal combustion engines, only about a third of the total fuel input energy is converted into useful work. If the energy rejected into the cooling system and the exhaust gases could be recovered instead and put into useful work, fuel economy would have been substantially improved. The main aim of this research paper was to evaluate the effects of the hybrid nano-catalyst containing ce...
In this paper, graphene oxide decorated with cerium oxide (CeO2) nanoparticles was prepared and used as anticorrosive pigments in epoxy nanocomposite coatings. The synthesized nanoparticle was characterized by FTIR, XRD, SEM, and EDX analyses. Graphene oxide decorated with CeO2 nanoparticles was dispersed in epoxy resin by sonication. The optimum nanoparticle content of th...
Nowadays engineered nanomaterials (ENM) are widely used in different customer products that lead to their released into the environment. The ENM behavior in aquatic system is influenced by many factors including water chemistry, presence of natural colloids, biota etc. Despite intensive research conducted in this area the fate of ENM in aquatic system isn’t clearly understood that poses the thr...
Electrorheological (ER) polishing as a new type of technique has flexibility and controllability. However, ER cannot be widely used in actual processing because the present fluid is usually prepared by simple mixing abrasive materials into fluid, which easy to occur phase separation decreased performance. This paper develops material based on cerium-doped titanium dioxide. As classic abrasive, ...
Cerium oxide nanoparticles are potent antioxidants, based on their ability to either donate or receive electrons as they alternate between the +3 and +4 valence states. The dual oxidation state of ceria has made it an ideal catalyst in industrial applications, and more recently, nanoceria's efficacy in neutralizing biologically generated free radicals has been explored in biological application...
