Traditionally found in particle-physics and cosmology contexts, the relativistic Dirac equation also describes how electrons move in a unique two-dimensional condensed matter system, graphene. Graphene, a single, one-atom-thick sheet of carbon atoms arranged in a honeyco lattice, is the two-dimensional building block for carbon materials of every other dimensionality.

The mass spectrum in Figure 10b was obtained from the as-deposited films. It is interesting to consider because it is typical of the level of complexity encountered in compound materials. Molecular ions such as HfO, HfO 2 , SiO, SiO 2 , TiN, and N 2 , in addition to the monatomic ion species, are observed in the mass spectrum throughout the stack.

Slice of History - A Knife Retrospective

Pattern-welding is another technique similar to laminate construction, which welds various steel types in layers, but then the stock is manipulated to create patterns in the steel. A lighter, more wear resistant metal, titanium is more flexible than steel, although it is unable to take as sharp an edge.

Graphene - Wikipedia

Graphene / ˈ ɡ r æ f iː n / is an allotrope of carbon consisting of a single layer of atoms arranged in two-dimensional honeyco lattice. The name is a portmanteau of "graphite" and the suffix -ene, reflecting the fact that the graphite allotrope of carbon consists of stacked graphene layers.
