Combined with cold-drawing and heat-treatment processes, ... Graphene is a one-atom-thick planar sheet of sp2-bonded carbon atoms that are densely packed in a honeycomb crystal lattice.

Plotting a graph takes time. Often mathematicians just want to know the key features. These are: shape, location and some key points (such as where the graph crosses the axes or turning points).

Before we can use data it needs to be collected. A computer can quickly create a chart or graph from our data. It can create a chart or graph much quicker than a human can. It's more difficult to ...
