TCNTs with armchair patterns

Achiral TCNTs can be classified into four different families according to two different patterns, armchair and zigzag, they can choose in the inner- and out-rim regions. Most of the beaded TCNTs we made have zigzag patterns in their outer-rim.
Here is a beaded TCNT with armchair patterns in both inner- an outer-rims.


10 mm beads are used in this beaded model.

Icosahedron

Platonic Solids

I bought these elongated beads last week, on sale, of course. The shape of these beads are closer to that of chemical bonds. I have used these beads to create five Platonic solids. They look great.

Tetrahedron


Cube



Octahedron




Dodecahedron
