An Overview of Mechanical Properties of Diamond-like Phases under Tension

Nanomaterials
Diamond-like phases are materials with crystal lattices very similar to diamond. Recent results suggest that diamond-like phases are superhard and superstrong materials that can be used for tribological applications or as protective coatings.

Modeling C540-C20 Fullerene Collisions

Reviews on Advanced Materials Science, 2018
Collisions of C20 and C540 fullerenes are studied in a wide range of velocities by means of classical molecular dynamics. The simulations show that the collision scenario strongly depends on the collision velocity of the fullerenes.
