DRIVING HAZARDS. The summit access road is approximately 10 miles long and has an altitude change of nearly 5,000 feet (1,510 m). There are many sections with a grade of 15 percent.
In simple terms, graphene, is a thin layer of pure carbon; it is a single, tightly packed layer of carbon atoms that are bonded together in a hexagonal honeycomb lattice. In more complex terms, it is an allotrope of carbon in the structure of a plane of sp2 bonded atoms with a molecule bond length of 0.142 nanometres.
As a result, atoms are usually stable so long as the number of protons and neutrons is not too uneven. If this balance isn't right, atoms can split apart through radioactive decay or nuclear fission. If an atom gets too heavy with neutrons, extra neutrons simply won't stick at all â not even for an instant.
