among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...

The global demand for plastics is increasing due to it wide applications. About 60 to 80 percent of the waste of the marine environment belong to plastic class. There is a lack of information and research on the presence of plastic and micro-plastic contamination in aquatic animals, The present study, therefore examined the frequency, distribution, size, color and type of micro-plastic (MPS) in...
