THE BEADED MOLECULES
串珠分子模型的美妙世界

I made two more bead models for toroidal carbon nanotubes with 120 and 240 carbon atoms last weekend (Christmas holliday in many countries, ...

Chuang and I are particularly interested in toroidal shape of graphitical structures or carbon donuts. Systematic structural rules of this t...

Here are a few toroidal carbon nanotubes I made a long time ago. There are two types of TCNTs. Smaller TCNTs consist of 120 carbon atoms. So...

This is the first beaded T240 I made right after I bought the materials from the Little Bear's Mother and made my first C60 last year. T...

Finally, I have all 12 isomers of T240: The corresponding computer-generated geometry for these models are The one with orange color is the ...

I guessed I must have lost count how many beaded models I have made. In fact, I made a twisted T240 isomer derived from the parent isomer, I...

Here is the list of stable isomers of T240. According to Chuang's generation algorithm for the toroidal compounds, there are 40 isomers ...

According to Chuang's exhausted search of carbon tori with 240 atoms and simultaneously satisfying C5 rotational symmetry and IPR (Indep...

It is amazing that scanner can be used to get pretty nice pictures for the torus.

In the process of weaving either branches of the toroid, it is not hard to notice that the beads on the edge form a large pentagon. It is un...

Here are ten isomers of T240 I currently made. I guess there are at least two more high-symmetry T240 in this family. You can see the two em...

The part for the making of inner-rim is the same as that of D 5h T240 b. The making of the out-rim From Craft Projects From Craft Projects ...

I have managed to make the chiral isomer of T240 (D 5h ) by shifting the pentagons on the outer rim by one bead. Unfortunately, I was unable...

There are many different types of T240. Previously, the three isomers I have shown all have the same inner rim configuration, but with diffe...

I found it is also easier to see the difference between these three isomers from a different view angle. Here is the side view of the previo...

Here are another examples of beaded toroids, C240. These two structures contain 360 beads each, thus 360 CC bonds. The details of construct...
