This book includes the synthesis, analysis and characterization of nanomaterials that are an important ingredient in nanotechnologies. Nanomaterials contain nanoparticles, smaller than 100 nanometers in at least one dimension. Nanomaterials are coming into use in health care, electronics, cosmetics and other areas. Their physical and chemical properties differ from those of bulk materials. This needs to cover health risks to workers and potential risks to environment. This is currently done on a case-by-case basis, but risk assessment methods need to be kept up to date as the use of nanomaterials expands, especially as they find their way into consumer products. This book covers the basics to advanced applications of nanomaterials and provides a useful resource for researchers and professionals in the field.
