Sorting the semiconducting wheat from the metallic chaff: Carbon nanotubes get closer to industrial purity

A few years ago, carbon nanotubes (CNTs) were touted as the Wave of the Future that would revolutionize materials engineering from semiconductors to space elevators. These days, CNTs have largely been obscured by the mad rush to research graphene (though not entirely), but there’s still some work being done on nature’s version of the ultimate Fruit Roll-up. This week, scientists ...
