Straw model of the elevated icosahedron (himmelis)

Two bead models for the JMM math art exhibitions

Chia-Chin and I submit two bead structures for the coming Joint Mathematical Meeting next January. These two models are made almost four years ago.

A paper for the Chemical Education in Taiwan

We published a paper in Chinese for the Chemical Education in Taiwan (台灣化學教育). The title is "奈米世界的構築藝術：第一型晶籠水合物的串珠模型之結構與製作" (Architectural Beauty in Nano World: The Structures and Construction of Type I Clathrate Hydrate).
In the future, I hope I can find time to write another two manuscripts for type II and type H Clathrate Hydrates.

附中「藝數創課」

跟師大附中合作的「化數為藝」特色課程，星期三做了第三次的教師增能工作坊，題目為「奈米無機世界的構築藝術-從數學串珠到分子桁架結構」。 海報與幾張照片：

A video on youtube

I just noticed a video "串珠與奈米世界的火花 (Sparkling Between Beading and Nano World)" on youtube which was apparently made by my school, National Taiwan Unversity.


The photos in this video were taken by Ying-Rong Chen.

A few bead models of diamondoid molecules

Mathematical beading can be used to construct any diamondoid molecule, also known as nanodiamonds or condensed adamantanes. Here, I show three such molecular systems:

Adamantane (C₁₀H₁₆);
Diamantane (C₁₄H₂₀) also diadamantane, two face-fused cages;
One of 9 isomers of Pentamantane with chemical formula C₂₆H₃₂.

Exhibition at the National Center for High-Performance Computing

We have the first exhibition at the National Center for High-Performance Computing, Hsin-Chu, Taiwan

Talk on the connection between bead models and chemical bonding

The three figures at the bottom are taken from the works of Su and Prof. W. Goddard III at Caltech. These figures show electron density profiles based on the so-called electron Force Field, which is essentially a simplified floating spherical Gaussian orbital method with an empirically fitted Pauli potential that takes care of the antisymmetric property of electrons.
