It's the basis of life on Earth, and comes in a variety of forms. Its unique chemical structure makes it readily bond with other atoms to form molecules, whether with other elements or itself. © IBM Research One of those forms, cyclocarbons, form a perfect ring. They've been teased out in the lab before, but only in gaseous states that quickly wore away. They could potentially have some interesting properties if we could find a way to work with them. But cyclocarbons are tricky. They're really volatile— so reactive, in fact, that studying them has proven to be a fool's errand. But research published in Science today changes that. For the first time, a cyclocarbon— known as cy...
