Adopting an advanced microscopic model of the Au–graphite interaction, a systematic study of Au nanoclusters (up to sizes of 11 238 atoms) on graphene and on graphite is carried out to explore their structure and energy landscape. Using parallel te

High entropy alloys (HEAs) are designed by mixing multiple metallic species in nearly the same amount to obtain crystalline or amorphous materials with exceptional mechanical properties. Here we use molecular dynamics simulations to investigate the r

Automatic design of mechanical metamaterials is key to achieving efficiencies in terms of a desired functionality that can far exceed the rationally designed man-made solutions. Here, we introduce a discrete element model capable of describing the me
