(Phys.org)—A group of researchers from the University of Groningen in the Netherlands have developed a way to change the handedness of a double-stranded metal helicate by photo and thermal stimulation by attaching bipyridine ...
Constructing nanomachines that move controllably across surfaces has the potential to enable researchers to build structures on the nanoscale from the bottom up, but is challenging on several fronts. How such a device can ...
