Anyone can make a Möbius strip using a piece of paper and some adhesive tape, now chemists have made one using the molecular building blocks carbon nanotube instead
A short section of carbon nanotube built from scratch forms a tiny Möbius strip – a one-sided surface that results from a band with a twist in it.
You would imagine you could just salami slice a carbon nanotube to get a band. But the tubes are difficult to manipulate because they are so small. They can’t be cut into cylindrical bands – which chemists call carbon nanobelts – as a tube of paper might be due to the powerful intramolecular forces at nanometre scales.
“The ultimate goal of organic chemistry is to create all possible molecular structures,” says Segawa. “Our achievement is one great step toward that purpose.” After they had carried out the modified chemical reactions, Segawa and his team confirmed the resulting structure really was a Möbius strip using high-resolution spectroscopy.
While an immediate use for the carbon Möbius strip might not be apparent, the finesse required to create it could lend itself to other challenges in nanoengineering and chemistry, says“The precise application for this Möbius band may not be an obvious one, even for the researchers who have researched it, but if they can extend their magic chemistry to larger systems and achieve ultimate control of larger carbon systems, then you can start to think about upscaling and scaling to wet...

Widespread disbelief over N. Korea's tiny COVID death rateSEOUL, South Korea (AP) — According to North Korea, its fight against COVID-19 has been impressive: About 3.3 million people have been reported sick with fevers, but only 69 have died. If all are coronavirus cases, that's a fatality rate of 0.002%, something no other country, including the world's richest, has achieved against a disease that has killed more than 6 million people.
