Nanotechnology: The Small Science with Big Potential
What is Nanotechnology?
Nanotechnology involves manipulating materials at the nanoscale—structures between 1 and 100 nanometers (a nanometer is one-billionth of a meter). Working at this scale unlocks unique material properties that aren’t present at larger sizes. For example:
- Enhanced Strength: Materials like carbon nanotubes are stronger than steel but lighter than aluminum.
- Improved Efficiency: Nanomaterials can conduct heat and electricity better than conventional materials.
- Self-Healing Capabilities: Nano-engineered coatings and composites can repair minor damages automatically.
These properties allow engineers to reimagine traditional materials and systems, making them lighter, stronger, smarter, and more sustainable.
