Nanomaterials research - Nanotechnology

What are Nanomaterials?

Nanomaterials are materials with structural components smaller than 100 nanometers. They exhibit unique properties due to their small size and large surface area, distinguishing them from their bulk counterparts. These materials can be in the form of nanoparticles, nanotubes, nanowires, and nanocomposites.

Why are Nanomaterials Important?

Nanomaterials have revolutionary potential across various fields due to their unique mechanical, electrical, optical, and magnetic properties. These properties enable breakthroughs in electronics, medicine, energy storage, and environmental remediation. For instance, carbon nanotubes offer unparalleled strength and electrical conductivity, while quantum dots provide exceptional optical properties for display technologies.

How are Nanomaterials Synthesized?

Synthesis of nanomaterials can be achieved through various methods categorized into top-down and bottom-up approaches. Top-down methods, like lithography and ball milling, involve breaking down bulk materials into nanoscale structures. Bottom-up methods, such as chemical vapor deposition and sol-gel processes, build nanostructures atom-by-atom or molecule-by-molecule.
