Researchers have created a reversible rotor that sits atop a ball bearing — a single ruthenium atom, Ars Technica reports.
The base of the system involves a boron atom that coordinates three ringed structures that are chemically similar to the bases of DNA. Nitrogens at a corner of these ringed structures coordinate the ruthenium atom, placing it at the peak of a three-sided pyramid.
The ruthenium atom acts… read more
