Abstract
Carbyne is a nanomaterial of great interest due to its ability to withstand high forces similarly to other carbon allotropes such as graphene or carbon nanotubes. However, it is currently difficult to synthesize and maintain without the assistance of a composite material substrate that the carbyne can be integrated with, which will affect its reaction to varying conditions. This thesis focuses on studying the effects of carbyne on a nickel surface and its mechanical properties to predict its future usages and potential for applications in varying fields. We perform a three-point bending test simulation using molecular dynamics with pure Ni (111) and a varying number of carbyne chains on its surface. The research concluded that a nickel substrate negatively affects the stiffness of carbyne and the nickel-carbyne composite due to the resulting change in the bond length of the carbyne under bending.
