This Physorg story gives the details, hat tip to Sander Olsen…
Scientists from A*STAR’s Institute of Materials Research and Engineering (IMRE), led by Professor Christian Joachim, have scored a breakthrough in nanotechnology by becoming the first in the world to invent a molecular gear of the size of 1.2nm whose rotation can be deliberately controlled. This achievement marks a radical shift in the scientific progress of molecular machines and is published in Nature Materials, one of the most prestigious journals in materials science.
