Scientists made a Möbius strip out of a tiny carbon nanobelt

From cylindrical nanotubes to the hollow spheres known as buckyballs, carbon is famous for forming tiny, complex nanostructures (SN: 8/15/19). Now, scientists have added a new geometry to the list: a twisted strip called a Möbius carbon nanobelt.

Möbius strips are twisted bands that are famous in mathematics for their weird properties. A rubber band, for example, has an inside and an outside. But if you cut the rubber band crosswise, twist one end and glue it back together, you get a Möbius strip, which has only one face (SN: 7/24/07).

In 2017, researchers created carbon nanobelts, thin loops of carbon that are like tiny slices of a carbon
