NanotechnologyAn Introduction

Nanotechnology

• A new interdisciplinary field of science• The study of systems at the nanoscale• The use of tools at the nanoscale• Building and applying structures that are

constructed atom by atom

3

What is it?Simply: • The ability to do things – measure, see,

predict and make – on the scale of atoms and molecules.

• The length scale of nanotechnology is the nanometer.– 1 nanometer = 10-9 meters is 1/100, 000 width of a

human hair

Size Matters

Physical processes do not scale uniformly– Gravity– Friction– Combustion– Electrostatic– Van der walls– Brownian– Quantum

A Nanotechnology Can Exist There’s Plenty of Room at the BottomDecember 29th 1959

– Manipulating and controlling things on a small scale– Write the Encyclopedia Brittanica on the head of a pin

• How do we write small?• Information on a small scale• Better electron microscopes

– The marvelous biological system– Miniaturizing the computer– Miniaturization by evaporation– Problems of lubrication– A hundred tiny hands– Rearranging the atoms– Atoms in a small world

Nanotechnology

• Has a long history• Has a solid theoretical basis• Has been looked at seriously for nearly

30 years

• So, what is it?

Currently Marketed Value-Added Products

• Wrinkle- and stain-resistant fabrics courtesy of Nano-Tex, now found at Eddie Bauer, The Gap, and Old Navy

• Ski jackets from German Franz Ziener GmbH using Nano-Tex enhancements to make them windproof, waterproof, breathable, and grime-resistant

• Babolat tennis rackets lightened and strengthened with Nanoledge nanotubes, and Wilson Double Core tennis balls containing InMat nanomaterials to lock in air

24

Currently Marketed Value-Added Products

• Nanostructured ceramic coatings from Inframatthat add durability and toughness to Navy ship hulls

• Antimicrobal bandages from NuCryst using nanocrystalline silver to kill microbes; more than 100 of the 120 major burn treatment centers in North America use these bandages to treat life threatening burns

• Duravit sinks and toilets with an easy-clean nanocoating from Nanogate
