Figure 1 shows a high-resolution transmission electron micrograph of an 18-shell carbon nanotube produced in this way: each dark line represents the side wall of a cylindrical graphene shell in ...

This is one electron. The fragile bond required outside-the-box thinking, with a complex molecule acting as a shell. From the omnipresence and ubiquity of carbon—it has its own branch of ...

Some elements in the periodic table, such as carbon, silicon, and germanium, are intrinsic semiconductors due to the number of electrons in their outermost electron shells. By comparison ...

and carbon-rich dust forms. Webb's latest observations show 17 dust shells shining in mid-infrared light that are expanding at regular intervals into the surrounding space. "The telescope not only ...
