Scientists made a Mobius 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 Mobius carbon nanobelt.
In 2017, researchers created carbon nanobelts, thin loops of carbon that are like tiny slices of a carbon nanotube. That feat suggested it might be possible to create a nanobelt with a twist, a Mobius carbon nanobelt. To make the itsy-bitsy twisty carbon, some of the same researchers stitched together individual smaller molecules using a series of 14 chemical reactions, chemist Yasutomo Segawa of the Institute for Molecular Science in Okazaki, Japan, and colleagues report May 19 in Nature Synthesis.
While carbon nanotubes can be used to make new types of computer chips and added to textiles to create fabric with unusual properties, scientists don't yet know of any practical applications for the twisty nanobelts (SN: 8/28/19; SN: 2/8/19). But, Segawa says, the work improves scientists' ability to make tiny carbon structures, especially complicated ones.
