Nanomaterials and its role in future....
Nanomaterials are materials that have at least one dimension in the nanometer scale (1-100 nanometers). Due to their small size, they exhibit unique physical, chemical, and biological properties that differ significantly from those of bulk materials. Types of Nanomaterials 1.) Carbon based nanomaterials: Graphene : A single layer of carbon atoms arranged in a two-dimensional lattice, known for its exceptional strength and electrical conductivity. Carbon Nanotubes (CNTs) : Cylindrical nanostructures with remarkable strength, electrical conductivity and thermal conductivity. 2.) Metal-Based Nanomaterials: These consist of metal nanoparticles (NPs) or nanostructures. Metal Nanoparticles: Made from metals like gold, silver, platinum, or copper. They are used in catalysis, medicine, and sensing due to their unique optical and chemical properties. Metal Oxide Nanoparticles: Common examples include zinc oxide (ZnO), titanium dioxide (TiO2), and iron oxide (Fe3O4) nanoparticles. These ...
