Pencils aren’t supposed to flex. When I investigated, I found that the manufacturer had decided to mix sawdust with some sort of adhesive and use the resulting substance to make ...

The voltammetric behaviors of AC on modified pencil graphite electrode were investigated by cyclic voltammetry and differential pulse voltammetry in phosphate buffer solution. The voltammetric studies ...

Some people think this refers to the Mohs hardness scale, which compares the ... uses the hardest type of graphite you can have in a pencil, won't scratch the screen under normal conditions.

Even more surprising? The researchers found this exotic behavior in a very familiar substance: graphite, the same material used in pencil lead. Graphite is made up of countless layers of graphene, a ...
