Imogolite in water: Simulating the effects of nanotube curvature on structure and dynamics
Gonzalez, Rafael I. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile]; Valencia, Felipe J. [Univ Mayor, Fac Estudios Interdisciplinarios, Ctr Invest DAiTA Lab, Chile]; Rojas-Nuñez, Javier; Muñoz, Francisco; Baltazar, Samuel E.; Allende, Sebastián; Rogan, José; Valdivia, Juan Alejandro; Kiwi, Miguel; Ramírez, Ricardo; Greathouse, Jeffery A. (Elsevier BV, 2019-07)Imogolite is a fascinating inorganic nanotube that is found in nature or synthesized in a laboratory. The synthesis process is carried out in liquid media, and leads to the formation of almost monodisperse diameter nanotubes. ... -
Mechanical performance of lightweight polycrystalline Ni nanotubes
González, Rafael, I [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Santiago, Chile]; Valencia, Felipe [Univ Mayor, Fac Ciencias, DAiTA Lab, Santiago, Chile]; Rojas-Nunez, Javier; Bringa, Eduardo M.; Allende, Sebastián; Palma, Juan L.; Pereira, Alejandro; Escrig, Juan; Baltazar, Samuel E. (ELSEVIER SCIENCE BV, 2019)The mechanical properties of metallic nanowires and nanotubes were investigated using atomistic molecular dynamics simulations on Ni polycrystalline structures, similar to those experimentally obtained by Atomic Layer ... -
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 ... -
Toward Controlled Morphology of FeCu Nanoparticles: Cu Concentration and Size Effects
González, Rafael I. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Santiago, Chile]; Rojas-Nuñez, Javier; Bringa, Eduardo M.; Allende, Sebastián; Sepulveda, Pamela; Arancibia-Miranda, Nicolás; Baltazar, Samuel E. (AMER CHEMICAL SOC, 2018)Bimetallic nanoparticles (NPs) can be tailored by varying the concentration of their constituent elements, resulting in novel structures and/or configurations, leading to interesting electronic, mechanical, and chemical ...
