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, ...
