The Atomic Difference Between Diamonds and Graphite

Everything is made of atoms. Usually these atoms are strongly connected to one another, in an amazing variety of configurations. But atoms are so tiny, how can we possibly understand the structure of matter at the atomic level? You probably have seen pictures of molecules or materials, zoomed in to the atomic level, which show …

Nanotechnology Through History: Carbon-based Nanoparticles from Prehistory to Today

Since our early ancestors first learned to make fires, humans have been producing carbon-based nanoparticles. The smoke and soot from their campfires contained nanoparticles known as fullerenes and carbon nanotubes, along with many other combustion by-products. They must have thought the very crude nanoparticle preparations they created were a bit of a nuisance (depending on …
