Understanding the Stability of Hollow Nanoparticles with Polycrystalline Shells
(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 ...
Thermal Stability of Hollow Porous Gold Nanoparticles: A Molecular Dynamics Study
(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 ...
Collisions between amorphous carbon nanoparticles: phase transformations
(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 ...
Shear transformation zones structure characterization in Cu50Zr50 metallic glasses under tensile test
(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 ...
