View from within a flattened, twisted carbon nanotube
A team led by Vincent Crespi at PennState used supercomputers to model the electronic states and total energies of various carbon molecules and discovered a tetrahedral carbon atom that creates tight and stable bonds to form tiny tubes only six atoms across -- the smallest diameter theoretically possible. Pictured here is a view from within a flattened, twisted carbon nanotube.
