What is Nanomaterial Engineering?
Nanomaterial engineering is a branch of nanotechnology that focuses on the design, synthesis, and application of materials with nanoscale dimensions. These materials, often referred to as
nanomaterials, typically have at least one dimension in the range of 1 to 100 nanometers. At this scale, they exhibit unique properties that differ significantly from their bulk counterparts, making them highly advantageous in various applications.
How are Nanomaterials Synthesized?
Nanomaterials can be synthesized using several methods, broadly categorized into top-down and bottom-up approaches. The
top-down approach involves breaking down bulk materials into nanoscale particles, often using mechanical milling or lithography techniques. The
bottom-up approach, on the other hand, involves assembling nanomaterials from atomic or molecular units through chemical vapor deposition, sol-gel processes, or self-assembly.
