Atomic force microscopy (AFM) is a standard imaging technique for the structural characterization of surfaces in different fields of materials science, surface science, and biology. Carbon nanotubes ...

Carbon is known for its plentiful allotropes, such as the naturally existing graphite and diamond, as well as synthetic compounds like the "buckyball" fullerene and graphene. Due to its unique valency ...

After some 30 years of trying different approaches to make a predicted allotrope of carbon, chemists have finally done it with a little atomic manipulation. The result is a ring of 18 carbon atoms ...
