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.
The carbon atom number 1 (C1) in one sugar is linked to the fourth carbon atom (C4) of the next sugar in an extended array. All the glucose molecules in cellulose have the beta-configuration at the C1 atom, so all the glycosidic bonds that join the glucose molecules together are also of the beta type. This means that the cellulose molecule is straight, and many such molecules can lay side by side in a parallel series of rows.
