(UWC, 2012)
Natural products have been a source of many pharmaceutical drugs and a number of drugs that are currently used in the treatment of cancer are derivatives of compounds originally isolated from natural products. There is ...
Graphene based nano-coatings: synthesis and physical-chemical investigations
(UWC, 2012)
It is well known that a lead pencil is made of graphite, a naturally form of
carbon, this is important but not very exciting. The exciting part is that
graphite contains stacked layers of graphene and each and every layer ...
