Laboratory 11 «Physics and Mechanics of Carbon Nanomaterials» was foundated in 2021 at IPSM RAS as part of the program for the youth laboratories on the basis of the Eurasian Scientific and Educational Center.

 

Research areas:

  1. Modeling the structure of carbon nanomaterials (graphene, nanotubes, fullerenes, bulk materials based on them and their modification under elastic deformation.
  2. Molecular dynamics simulation of the stability of new carbon nanomaterials.
  3. Study of the mechanical properties and deformation behavior of carbon nanomaterials by molecular dynamics.
  4. Study of the defect structure and dynamics of defects in carbon structures.

The main scientific results:

  • A method for calculating the stiffness and compliance constants of three- and two-dimensional structures combining the molecular dynamics and analytical calculations has been developed. It has been shown that Young's modulus and Poisson's ratio depend on the hybridization of the material, as well as on the packing of atoms in two-dimensional crystals.
  • Using diamane as an example, it has been shown that the strength of a two-dimensional material depends on its chirality. It has been shown that diamane with a chirality of 10 degrees has the greatest strength. In addition, during the process of diamane stretching, a phase transformation occurs that changes the chirality of diamane and its properties.
  • A method for obtaining a graphene/metal composite by means of high-temperature hydrostatic compression has been proposed. The optimal temperature of deformation treatment has been determined: 0.7 of the melting temperature of metal nanoparticles. It has been shown that suchcomposite coating can increase the strength and hardness of the metal surface.
  • The mechanisms of formation of graphene/copper composite nanoparticles during synthesis in plasma jet have been revealed.
