On the impact of capillarity for strength at the nanoscale
Nadiia Mameka, Jürgen Markmann, Jörg Weissmüller
The interior of nanoscale crystals experiences stress that compensates the capillary forces and that can be large, in the order of 1 GPa. Various studies have speculated on whether…
X-Ray Studies of Nanoporous Gold: Powder Diffraction by Large Crystals with Small Holes
Matthias Graf, Bao-Nam Dinh Ngô, Jörg Weissmüller +1
X-ray diffraction studies of nanoporous gold face the poorly understood diffraction scenario where large coherent crystals are riddled with nanoscale holes. Theoretical considerati…
On the origin of the anomalous compliance of dealloying-derived nanoporous gold
B. -N. D. Ngô, B. Roschning, K. Albe +2
The origin of the anomalously compliant behavior of nanoporous gold is studied by comparing the elasticity obtained from molecular dynamics (MD) and finite element method (FEM) sim…
Anomalous compliance and early yielding of nanoporous gold
Bao-Nam Dinh Ngô, Alexander Stukowski, Nadiia Mameka +3
We present a study of the elastic and plastic behavior of nanoporous gold in compression, focusing on molecular dynamics simulation and inspecting experimental data for verificatio…
Switchable Imbibition in Nanoporous Gold
Yahui Xue, Juergen Markmann, Huiling Duan +2
Spontaneous imbibition enables the elegant propelling of nano-flows because of the dominance of capillarity at small length scales. The imbibition kinetics are, however, solely det…
Diffraction microstrain in nanocrystalline solids under load - heterogeneous medium approach
Jürgen Markmann, Dmitriy Bachurin, Lihua Shao +2
This is an account of the computation of X-ray microstrain in a polycrystal with anisotropic elasticity under uniaxial external load. The results have been published in the article…
