This is a large physical molecular model for the extended metal atom chain consisting of 11 Nickel atoms and four surrounding ligands hung at the lobby of new chemistry building of National Taiwan university.

A giant model for the longest extended metal atom chains containing eleven Nickel atoms, still covered by steel scaffolding, is hung over the lobby of new chemistry building (NTU) yesterday.

I showed this beaded Mobius band to Prof. Yuan-Chung Cheng in our joint group meeting last Friday. Maybe it is because the talk was dull and he seemed to have concentrated more on this beaded model than on the talk. Or maybe he just like to figure out the maximal strength this band can endure. So he broke it.

Qian-Rui Huang showed me this remarkable beaded model for the (4,3) torus knot today. The model is not like the one for trefoil knot. It is quite soft and very crowded in the center since two tubes have to pass to each hole for the (4,3) torus knot. This problem is not very serious for the trefoil knot though. As I said before, one can in principle construct any kind of molecular graph. But only in certain situations, the resulting structure can simulate the real fullerene.
