Technological developments nanomaterials

Polychlorinated biphenyls (PCBs) were used in this chapter as an example of a technological development that resulted in unforeseen adverse consequences to the health of the environment. Briefly smnmarize why PCBs were developed, what types of environmental problems were discovered, and what was done to mitigate the problems once they were identified. (You may need to use Internet or other sources to gather this information.) Suggest at least one characteristic of nanomaterials that should be defined in order to prevent analogous adverse consequences. 

Nanoparticles, when engineered appropriately, exhibit a variety of unique and tuneable physicochemical properties [53, 54]. These characteristics have made engineered nanoparticles as central components in an array of emerging technologies with widespread potential applications in material sciences and engineering. Large quantities of nanomaterials are already commercially available for commercial scale applications due to the establishment of well-developed nanomaterial production methods such as chemical vapour deposition and electrospinning. As a... 

The Science of Nanomaterials is proving to be one of the most attractive and promising fields for technological development in this century. In the scientific literature several terms related to Nanoscience can be found, of which it is worth highlighting nanoparticles, nanocrystals, nanofibers, nanotubes and nano-composites. In fact, all these are related to nanostructured materials, which have well-defined structural features. The physical and chemical properties of materials at the nanometer scale (usually set in the range of 1-100 nm) are of immense interest and increasing importance for future technological applications. Nanostructured materials often exhibit different properties when compared to other materials. 

With 11 chapters contributed by world-class scientists and engineers, this book covers most recent developments in the science and technology of nanomaterials for lithium-ion battery applications. It addresses both academia and industry research and engineering in this fast-developing field.
