A read is counted each time someone views a publication summary such as the title, abstract, and list of authors, clicks on a figure, or views or downloads the fulltext. Production of nanomaterials has been constantly evolving over the last few years for manifold applications in electronic, optical and biomedical fields. This process leads to the higher level of understanding needed to resolve important issues, such as causes of failure and processrelated problems, and allows the manufacturer to make critical. Cnts are nothing but graphene sheets rolled into a tube. Nanotechnology is the study of phenomena and finetuning of materials at atomic, molecular and macromolecular scales, where properties differ significantly from those at a larger scale. Superfund researchers are also looking at how nanomaterials behave in the environment as they are used for remediation. A change in the rate of chemical reactions or their generation under the action of light in the presence of substances called photocatalysts that absorb light quanta and are involved in the chemical transformations of the reaction participants.

Material characterization is the process of measuring and determining physical, chemical, mechanical and microstructural properties of materials. As a result, exposure towards nanoparticles in the workplace environment is increasing, while respective occupational exposure limits are lacking.
