beaded vase

Bang-Rui's mother knew my hobby of making beaded molecules. So she gave me a beautiful beaded vase she made. It is basically a pillar-shaped C₈₄ with the top surface removed.

Here is a bead model of pillar-shape C₈₄ I made before.

The other two smaller fullerenes in the same homologous series are C₆₀ and C₇₂.

High-genus fullerenes

I made two more high-genus fullerenes with octagonal necks using 8mm beads and 0.6mm Nylon threads. If I remember everything correctly, Chern and I should have made four of this molecule (one in China and three in U.S.) before.

HG-Fullerenes with octagonal necks No. 5 & No. 6

Since this model contains less than one thousand beads, so I managed to finish one of them in a day.

形狀美麗的分子（Chemistry & Chemical Industry, Vol. 62, 2012）

Prof. Sonoda (園田高明) of Kyushu University sent me a special issue on "Beautifully Shaped Molecules" of "Chemistry & Chemical Industry" published by Japanese Chemical Society. There are five articles by famous Japanese chemists in this issue. The photos I showed here are from an article on "Self-Assembled Polyhedra" (my translation based on the Kanji in the title, I don't know Japanese, though) by Makato Fujita (藤田 誠) of Tokyo University.

Photos of Workshop for Exchange Students from Okayama Univeristy

Mr. Hwang took many photos for my workshop last Tuesday.

As usual, I gave a 30-min short talk before we started to make beaded C₂₀ and C₆₀.

While I was talking, students were free to examine the beadworks I brought to the workshop.

Prof. Sonoda (Kyushu University) also visited Taiwan in those few days. So I invited him to this workshop. He seemed to have fun making a beaded C₂₀.

Almost all of students succeeded in making their own C₂₀ and C₆₀ in this 3-hour workshop. You can see how happy they were when they finally made their own buckyballs.

After the workshop, I took a picture with my colleagues.

Another unfinished (1,1) P-surface

I found an unfinished (1,1) P-surface made by Chern before. I should have used it as the starting point last week.

P-surface with the Goldberg vector (1,1)

In principle, it is possible to construct a graphitic P-surface with neighbored octagons separated by any Goldberg vector, (h, k). Most of the beaded P-surfaces I posted before have the vector (2,0). The smallest graphitic P-surface has a vector of (h,k)=(1,0) and its bead model was built by Chern long time ago.

Here is the bead model of P-surface with (1,1) I made this weekend. Unlike (2,0)-surface, the bead model of (1,1)-surface is a little bit crowded though.
