Size and temperature dependent magnetization of iron nanoclusters
(Chile. Universidad Mayor, 2020)
The magnetic behavior of bcc iron nanoclusters, with diameters between 2 and 8 nm, is investigated by means of spin dynamics simulations coupled to molecular dynamics, using a distance-dependent exchange interaction. ...
FoamExplorer: Automated measurement of ligaments and voids for atomistic systems
(Elsevier, 2020-12)
Atomistic simulations are often used to explore the mechanical and chemical properties of a variety of materials and structures, such as nanowires, whiskers, nanospheres, nanotrusses, and nanoscale foams, among others. ...
MeV irradiation of tungsten nanowires: structural modifications
(IOP Publishing Ltd., 2020-05)
In this work we use the Two Temperature Model coupled to Molecular Dynamics (TTM-MD) to study swift heavy ion irradiation of W finite nanowires. Au projectiles are considered with energies ranging from 20 to 50 MeV, which ...
Nanoindentation of polycrystalline Pd hollow nanoparticles: Grain size role
(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, ...
Modeling habitat suitability and spread dynamics of two invasive rose species in protected areas of Mendoza, Argentina
(Elsevier, 2020-12)
Biological invasions are a main threat to biodiversity and natural resources, which calls for studies that identify the regions that present the greatest invasion risks. We assessed the potential distribution of two ...
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 ...
Effect of Tip Roundness on the Nanoindentation of Fe Crystals
(Springer New York, 2020-04)
Indentation tips are never atomically sharp, but rounded at their end. We use atomistic simulation to study the effect of tip roundness for the particular case of a cube-corner pyramidal indenter by comparing the results ...
Effect of subsurface voids on the nanoindentation of Fe crystals
(IOP Publishing Ltd., 2020-03)
Subsurface voids may strongly affect the response of materials to nanoindentation. We explore these effects for a bcc single-crystalline Fe sample using molecular dynamics simulation. Deformation occurs mainly by nucleation ...
