Thermal stability of aluminum oxide nanoparticles: role of oxygen concentration
González, Rafael I. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Santiago, Chile]; Valencia, Felipe J. [Univ Mayor, Fac Ciencias, DAiTA Lab, Santiago, Chile]; Ramírez, Max; Baltazar, Samuel E.; Rojas-Nunez, Javier; Allende, Sebastián; Alejandro Valdivia, Juan; Rogan, Jose; Kiwi, Miguel (ROYAL SOC CHEMISTRY, 2019)Oxygen absorption and the thermal stability of Al-147 nanoparticles were studied by means of classical molecular dynamics simulations and Monte Carlo methods. The results suggest that for the studied sizes, oxygen incorporation ... -
Understanding the Stability of Hollow Nanoparticles with Polycrystalline Shells
Valencia, Felipe J. [Univ Mayor, Fac Estudios Interdisciplinarios, Ctr Invest DAiTA Lab, Chile]; Ramírez, Max; Varas, Alejandro; Rogan, José (Chile. Universidad Mayor, 2020)The existence of polycrystalline shells has been widely reported in the synthesis of hollow nanoparticles; however, the exact role displayed by the grain boundaries on the stability has been scarcely studied. By including ...
