SYNTHESIS AND CHARACTERIZATION OF NANO MATERIALS

Physics

Engineered nanomaterials are intentionally designed and created with physical properties tailored to meet the needs of specific applications. Non- engineered nanomaterials, on the other hand, are unintentionally generated or naturally produced, such as atmospheric nanoparticles created during combustion. N anomaterials deal with very f ine structures: a nanometer is a billionth of a meter. This indeed allows us to think in both the ‘ bottom up’ or the ‘ top down’ approaches to synthesize nanomaterials, i . e. either to assemble atoms together or to disassemble ( break, or dissociate) bulk solids into f iner pieces until they are constituted of only a few atoms. Nanomaterials are materials that show promising chemical and physical properties and have various important applications. In this project we have worked on the synthesis, characterization, and applications of nanomaterials. Nanomaterials can be synthesized by using different synthetic techniques. The formation, s tructure, s ize, surface morphology, thermal stability, and surface area of the s ynthesized nanomaterials can be characterized by using different characterization t echniques such as FT- IR, XRD, SEM, TEM, UV- Vis and EDS. Nanomaterials are ver y interesting since they possess characteristics which are connections between bulk material and atomic s t ructures. Synthesis and characterization of nanomaterials can be addressed as a bridge between bulk material behaviors and molecular characteristics. Nanomaterials have size and shape dependent properties which make them totally different from bulk materials.
