Lack of understanding of the physical chemistry and their in vivo behavior still hamper full breakthrough in pharmaceutical industry.
B.Graphite is mostly used for refractory, battery, steel, expanded graphite, brake linings, foundry facings, and lubricants. Graphene, a naturally occurring ingredient in graphite, has unique physical properties and is one of the strongest known substances. The separation process from graphite, however, requires more technological development.
