Crater production by energetic nanoparticle impact on Au nanofoams
(American Institute of Physics, 2016-03)
Impact of energetic nanoparticles on solids produces craters on the surface. We use molecular dynamics simulations to compare crater production on a compact Au solid with that in a porous (foam) target. Our results show a ...
Sputtering of a metal nanofoam by Au ions
(Elsevier Science, 2015-01)
Porous materials, such as nanofoams, may react differently to irradiation than compact targets. This is caused by the influence of the cavities on the evolution of collision cascades, but also by the differing heat conduction ...
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. ...
Mechanical properties of Au foams under nanoindentation
(Elsevier, 2018-05)
Nanoscale metallic foams display mechanical properties which make them attractive for a variety of technological applications. We report simulated nanoindentation tests for a model polycrystalline nanoporous gold structure ...
Are nanoporous materials radiation resistant?
(American Chemical Society, 2011-06-09)
The key to perfect radiation endurance is perfect recovery. Since surfaces are perfect sinks for defects, a porous material with a high surface to volume ratio has the potential to be extremely radiation tolerant, provided ...
Mechanical properties of irradiated nanowires - A molecular dynamics study
(Elsevier, 2015)
In this work we study, by means of molecular dynamics simulation, the change in the mechanical properties of a gold nanowire with pre-existing radiation damage. The gold nanowire is used as a simple model for a nanofoam, ...

Molecular dynamics and Monte Carlo simulations of the sputtering of a nanoporous solid
(Elsevier, 2013-06-01)
We calculate the sputtering induced on a nanoporous material by fast penetrating ions, such as those used for track formation and surface modification, in order to better understand and quantify the ejection and redeposition ...
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 ...
Atomistic simulations of tensile deformation of a nanoporous high-entropy alloy
(2022-11)
Abstract: High-entropy alloys (HEAs) display outstanding mechanical properties which make possible new technological applications. There are many studies of bulk HEAs, but here we focus on FeCrNiCuCo single-crystal ...
