Collisions between amorphous carbon nanoparticles: phase transformations
Nietiadi, Maureen L.; Valencia, Felipe J. [Univ Mayor, Fac Estudios Interdisciplinarios, Ctr Invest DAiTA Lab, Chile]; Gonzalez, Rafael I. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile]; Bringa, Eduardo M. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile]; Urbassek, Herbert M. (EDP Sciences, 2020-09)Context. Collisions of nanoparticles (NPs) occur in dust clouds and protoplanetary disks.Aims. Sticking collisions lead to the growth of NPs, in contrast to bouncing or even fragmentation events and we aim to explore these ... -
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. ... -
Nanoindentation of polycrystalline Pd hollow nanoparticles: Grain size role
Pinto, Benjamin [Univ Mayor, Escuela Construcc, Chile]; Valencia, Felipe J. [Univ Mayor, Fac Estudios Interdisciplinarios, Ctr Invest DAiTA Lab, Chile]; Kiwi, Miguel; Ruestes, Carlos J.; Bringa, Eduardo M. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile]; Rogan, José (Elsevier, 2020-06)Polycrystalline hollow nanoparticles present a unique combination of strength and flexibility. However, the exact role displayed by their grain structure in mechanical properties has not been yet fully understood. Here, ... -
Shear transformation zones structure characterization in Cu50Zr50 metallic glasses under tensile test
Amigo, Nicolás [Univ Mayor, Fac Estudios Interdisciplinarios, Nucleo Matemat Fis & Estadist, Chile]; Urbina, Felipe [Univ Mayor, Fac Estudios Interdisciplinarios, DAiTA Lab, Chile]; Valencia, Felipe J. [Univ Mayor, Fac Estudios Interdisciplinarios, Ctr Invest DAiTA Lab, Chile] (Elsevier, 2020-11)The atomic structure of Cu50Zr50 metallic glasses under tensile test was investigated using molecular dynamics simulations. Voronoi polyhedra analysis was employed to calculate the number of neighbors for each atom, obtained ... -
Thermal Stability of Hollow Porous Gold Nanoparticles: A Molecular Dynamics Study
Valencia, Felipe J. [Univ Mayor, Fac Estudios Interdisciplinarios, Ctr Invest DAiTA Lab, Chile]; Ramirez, Max; Varas, Alejandro; Rogan, José; Kiwi, Miguel (American Chemical Society, 2020-12)Hollow nanoparticle structures play a major role in nanotechnology and nanoscience since their surface to volume ratio is significantly larger than that of filled ones. While porous hollow nanoparticles offer a significant ... -
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 ...
