High-temperature austenite, an FCC structure, has enough space for carbon atoms to squeeze in between the iron atoms. Iron atoms keep their place on the lattice while carbon atoms become ...

Structure of Carbon Nanotubes. Carbon nanotubes (CNTs) are cylindrical nanostructures formed by rolling a single layer of graphene into a seamless tube. The graphene sheet consists of carbon atoms ...

Carbon, one of the most abundant elements in the universe, constitutes many key components of life and technology. Because of ...

Carbon nanotubes are made from concentric layers of graphene, which consists of carbon atoms arranged in a 1D honeycomb lattice. Graphene sheets are electrically conducting – they have mobile ...

Save guides, add subjects and pick up where you left off with your BBC account. In chemistry, ‘bonding’ describes how atoms are held together. ‘Structure’ describes how atoms are arranged ...
