Nanotechnology-Size Matters
• Billionth of a meter (10-9 m)
• Nanomaterials- Materials with size 1-100 nm
• 0D,1D, 2D and 3D nanomaterials
0D 1D 2D 3D
• Properties are different at nanoscale.
Eg: Red Gold!
• Top down and Bottom up approach
Nature News, 2001
The color of gold becomes red at 20 nm!

Market structure: Carbon Nanotubes (CNT)
Single walled CNT
Few walled CNT
Multi walled CNT
Adoption in key markets like asphalt, concrete, energy storage expected in near future
SWeNT, Nanointegris, Thomas swan
SWeNT, Nantero, Lockheed martin, kuraray, brewer science
Showa denko, Arkema, Nanocyl, Timesnano, Hyperion, Chinese players
Product Companies Characteristics
Very few quality producers. No major players
Latest entrant in this space. Applications still developing
Mass applications, crowded market, few quality producers
10
Market structure: Graphene
Graphene Nano Platelets
Graphene sheets
Majors like Samsung, Sandisk, BASF etc. betting big on Graphene
Vorbeck, XOLVE,Haydale, graphenea, Samsung, IBM, BASF
Angstron Materials, Graphenics, Sandisk
Product Companies Characteristics
Energy storage considered to be the next big thing. Large MNCs investing in R&D. E.gIBM, BASF etc. but the market is overpopulated by low-quality players
Applications still in development stage. Large players investing heavily in R&D
