A remarkable discovery, with regards to graphite, was discovered a few years back by some foreign scientists working in the UK. The substance was named graphine, which seems unbelievable in the manner it was stumbled upon. Apparently, they used a piece of scotch tape and stuck it onto a piece of graphite, then studied the tape very closely, using a variety of measurement techniques, finding that at atomic level, the trace/lattice of graphite was extremely solid with recent tests suggesting that graphine could be 200 times stronger than steel, which is very interesting. There is a little more to it than this, but not much.
