A new poster - The Fabulous World of Beaded Molecules: Architectural Beauty of Zeolites (串珠分子模型的異想世界:沸石構築藝術之美)

Chia-Chin and I prepared a new poster, The Fabulous World of Beaded Molecules: Architectural Beauty of Zeolites (串珠分子模型的異想世界:沸石構築藝術之美), for a project we did together for the Ministry of Science and Technology (科技部).

Workshop for students from Kanagawa University

I gave one more workshop for students from Kanagawa university, Japan. Today, I tried something new, instead of working on C60 for each student, I asked them work on two zeolite structures, zeolite A and Faujasite, together after making the famous 30-ball Sangaku problem, which just gave them enough beading experience to move on. Both of these two zeolite structures consist of the same structural unit (Secondary Building Units, SBUs), namely truncated octahedrons. It seems to be easy for them to work together, then combine them into these two framework types. Here are a few pictures from the workshop.
Students were very happy when they succeeded in making the zeolite A.


Chia-Chin and I recently wrote a short overview manuscript entitled "Where Science Meets Art - The Fabulous World of Beaded Molecules" about beaded molecules for a meeting which will be held in Shandong, China this weekend.
Note: 由於這篇文章太晚寄出,最後未出現在論文集中。(Sept. 7, 2007) 我會另尋適當的雜誌發表。

Two articles about the construction of gyroid- and diamond-type triply periodic minimal surfaces

I wrote two articles in Chinese for the Journal, Chemistry Education in Taiwan (臺灣化學教育) last year. The pdf files have just come out:
1. 左家靜, 莊宸, 金必耀, 大家一起做多孔螺旋與鑽石型三度週期最小曲面的串珠模型(上)─立體幾何介紹,2014 臺灣化學教育, 328-335.
2. 莊宸, 左家靜, 金必耀, 大家一起做多孔螺旋與鑽石型三度週期最小曲面的串珠模型(下)─實作,2014 臺灣化學教育, 336-344.
The title can be translated as "Application of mathematical beading to carbon nanomaterials - A hands-on, collaborative approach to gyroid- and diamond-type triply periodic minimal surfaces with beads, I and II", literally. I described a simple modular approach which was developed mainly by Chern Chuang for making gyroid- and diamond-type Triply Periodic Minimal Surfaces.

Eight convex deltahedrons

I made all convex deltahedrons with tubular beads early this year. There are infinite deltahedrons, but only eight of them are convex.
