Síntese de nanopartículas de óxido de cromo a partir do método Sol-gel protéico
Medeiros, Angela Maria de Lemos; Silva, Erandir Brasil da; Flores, Wladimir Hernandes; Sasaki, José MarcosA first motivation for the development of materials in the nanometric scale is associated to the possibility that a larger number of them comes to be gathered in devices of very small dimensions, increasing miniaturization and capacity for processing information. This research reside in the fact that new and uncommon physical and chemical properties, absent in the same material in macro and microscopic size, ar...
Síntese e caracterização de nanopartículas de Cr2O3 através do método sol-gel p...
Medeiros, Angela Maria de LemosIn the last years, nanoparticles have becoming important to several researchers. This research reside in the fact that new and uncommon physical and chemical properties, absent in the same material in macro and microscopic size, are observed in this new scale. The subject of this study is obtaining chromium oxide nanoparticles (Cr2O3) by sol–gel proteic process using gelatin as an organic precursor. This proces...
