C70 and beaded pig

C70 is a cute molecule that can be used to build a model of pig by putting some peripheral parts on it.

New T240 with 3mm beads

It is nice to have T240 using 3mm beads. The structure of this model is stronger than those made with larger beads. This seems to be in agreement with the scaling law.

Fluorescent T420

Starting from the inner core of type 4 torus with large inner-rim radius, one can build another beautiful carbon torus which contains 420 carbon atoms. This model is made from 3 mm beads.

Beads with long aspect ratio

In the previous post, I shown two beautifully dual beaded models made by Chuang, which give an interesting application of beads with long aspect ratio. Due to the color of these beads, the contrast of these photos is not good. I made scanned images for these two new beaded models. The contrast seems to be better than the photo.

Previously, we have used this kind of beads to made a model of C60. The resulting structure is quite flexible and can be deformed easily under external stress. We claimed that beads with long aspect ratio is not suitable for constructing stable fullerenes. Now Chuang discovered that these beads are good for creating their dual structures. The rigidity of resulting structures are very large.

Dual of Beaded Molecules: C60 and T120

These couple of days I have been thinking about the usage of the rice-shaped beads we bought a long time ago when I just began to make beaded molecules. I realized at that time that they are not good materials for endurable beaded molecules since the structure is not stable usually. But it turns out that this kind of beads are quite suitable for constructing the duals of fullerenes. Take a look at the following two dual models, one for C60 and the other for T120, created by Chuang.

These dual beaded molecules have pretty good mechanical strength due to, in my speculation, the tensegrity of such structures.
