What Is Nanomanufacturing

• The ability to fabricate, by directed or
  self-assembly methods, functional structures or
  devices at the atomic or molecular
  level-Wikipedia
• Nano means one billionth of a meter
• Fabricating the components less than 100nm at the
  nanoscale
• Examples Making lighter Golf, Hockey and Base
  Ball sticks

Applications

• Biotech-Cancer Treatment
• Construction-Lighter and Resistant Materials for
  Building Homes
• Automobile-Wear Resistant Tires
• Science-Atomic structure
• Environmental-Solar cells
• Safety-Detect poisonous substances

4
Processes

• CAD Modeling at the atomic structure level
• Top Down Manufacturing
• Start with bulk material and remove what is
  not needed e.g Semiconductor Industry
• Bottom Up Manufacturing
• Building the products at the atomic level with
  digital precision and build up to larger objects

5
Top Down Processes

• Lithography- optical, UV based
• Fragmentation- mechanical milling
• Nano-machining-etch or remove small parts

6
Bottom Up Processes

• Nucleation and Growth - Deposition on Surfaces
• Self Assembly-Natural Processes in Living systems
• Templating - carbon nanotubes
• Molecular Assemblies-Design of molecules as
  device like logic devices
• Nanomanipulation-Nanoparticles

7
Applications In Industry

• Nanotubes, Nanorods, Nanostructures used in
  aircraft engines, health care
• In cars, nanoparticles are used in composite
  materials, pigments for paints
• Semiconductor companies are using nanoscale
  features to improve processing speed, memory
  capacity, reliability and control cost.

8
Applications In Industry

• Designing molecules for hierarchical
  self-assembly for use as biomaterials
• Micro and nano robots rely on new mechanisms
  based on the physics of the nanoscale. They will
  be smaller, faster, lighter, and cheaper, with
  direct access to small spaces and scales.
