Molecular dynamics simulations reveal the influence of solute segregation
Dislocation evolution in alloyed and pure nanoporous foams is studied by molecular-dynamics simulations. We find that the yielding behavior is dependent on surface compositions and the corresponding capillary forces, while elastic behavior is dependent on bulk composition. Trends in the yield response of this material as a function of size and surface composition are effectively predicted with a modelthat accounts for surface effects.

Atomistic insights into metal hardening
In contrast with conventional views, ultra-large-scale atomistic simulations show that the staged character of strain hardening of metals originates from crystal rotation, whereas the dislocation behaviours remain the same across all the stages.

New investigations on the exfoliabiltiy of maxenes
Ali Malik investigated the exfoliability of maxenes using DFT calculations. The results were published together with the C. Birkels group. The paper appeared on the front page of Dalton Transactions.
