  Structural, Electronic, and Antioxidant Properties of Ablated Ceo2 Nanoparticles with Controlled Limiting Size
  Author(s): Maxim Alexandrovich Pugachevskii*
  
  Ceria particles of nanodispersed composition have been obtained by laser ablation and subsequent treatment in an aqueous solution. Using techniques (TEM, XRD, Raman, EELS) of the nanostructural and electronic analysis, it is shown that the produced particles have structural defects that stabilize their internal structure. It is established that when the particle size decreases from 100 to 10 nm, the crystal lattice parameter lowers from 5.41 to 5.39 , and the elemental O/Ce composition changes from 1:1.83 to 1:1.76. The ablated CeO2 particles of nanodispersed composition exhibit high antioxidant activity due to the high concentration of functional defects on the surface of nanoparticles... Read More»
