The interface between physics, chemistry (and materials science) can be a fascinating one. Here I show a carbon nanotorus, devised by physicists a few years ago. It is a theoretical species, and was predicted to have a colossal paramagnetic moment.
At 1364 carbon atoms, it is a little too big to calculate any of its expected chiroptical properties (the torus twists in a helical manner, and so is chiral). So we can only speculate whether e.g. its optical rotation would also be colossal! Or, what applications such a nanodevice might have. This post, by the way, was induced by seeing Steve Bachrach’s fascinating exploration of chiral nanohoops.
