   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Michel Goy; [2019]
   Keywords : ;

   Abstract : Nanoparticles of cerium dioxide was synthesized by gamma irradiation of aqueous solutions containing CeCl3 and CeBr3. ICP-OES was used to determine the precipitation yield. X-ray powder diffraction and transmission electron microscope were used to characterize the products. READ MORE
