Bending energy of 2D materials: graphene, MoS2 and imogolite
González, Rafael I. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Santiago, Chile]; Valencia, Felipe J. [Univ Mayor, Fac Ciencias, Nucl Matemat Fis & Estadit]; Rogan, Joséé; Valdivia, Juan Alejandro; Sofo, Jorge; Kiwi, Miguel; Muñoz, Francisco (ROYAL SOC CHEMISTRY, 2018)The bending process of 2D materials, subject to an external force, is investigated, and applied to graphene, molybdenum disulphide (MoS2), and imogolite. For graphene we obtained 3.43 eV angstrom(2) per atom for the bending ... -
Growth of Ni nanoclusters on irradiated graphene: a molecular dynamics study
González, Rafael I. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Santiago, Chile]; Valencia, Felipe J. [Univ Mayor, Fac Ciencias, Nucl Matemat Fis & Estadit]; Hernández-Vázquez, E. E.; Bringa, E. M.; Moran-López, J. L.; Rogan, J.; Muñoz, F. (ROYAL SOC CHEMISTRY, 2018)We studied the soft landing of Ni atoms on a previously damaged graphene sheet by means of molecular dynamics simulations. We found a monotonic decrease of the cluster frequency as a function of its size, but few big ... -
Mechanical Properties Obtained by Indentation of Hollow Pd Nanoparticles
González, Rafael I. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Santiago, Chile]; Bringa, Eduardo M. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada]; Valencia, Felipe J.; Rogan, José; Valdivia, Juan Alejandro; Sofo, Jorge; Kiwi, Miguel; Muñoz, Francisco (AMER CHEMICAL SOC, 2018)Palladium nanoparticles are technologically important for catalysis, hydrogen storage, and many other applications. Here, we investigate the mechanical properties of Pd hollow nanoparticles of different sizes and thicknesses ... -
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 ...
