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.

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.
