  • Calculation of lattice parameters for transformed maps.
  • Strain energy calculations for large atomic structures.

Main Results:

  • Successful synthesis of schwarzites with 3D periodic covalent networks.
  • Development of formulas for lattice parameter calculations.
  • Demonstration of tessellation using geometric operations.
  • Strain energy calculations indicate high structural relaxation, approaching unstrained graphite.

Conclusions:

  • Schwarzites represent a new class of carbon allotropes.
  • The developed methods allow for the design and analysis of these complex nanostructures.
  • The inherent stability of schwarzites is confirmed by low strain energy.
