NanoscaleScience and Engineering


What is Nanoscale Science

and Engineering?

Engineering at the nanoscale is called Nanotechnology!


How small is a nanometer?


MACRO

meter

centimeter

All these are still visible with your eyes.

millimeter


6-8 µm

micrometer

(One-millionth of a meter)

MICRO

Nanoscale objects are 1,000 times smaller!!!

These are smaller than you can see.


NANO

A nanometer is one billionthof a meter!!

DNA

2.5 nm

Viruses

3-50 nm

Atoms

<1 nm


Nanotechnology

The nanometer is extremelysmall.

At the nanometer scale, many materials behave differently.

We can use this new behavior to make newtechnologies.


Nano in Nature


Apparel with silver nanoparticles

“Nano” all around us

Tata Nano

Babygear


Things are different . . .

Size really does matter!

Nanoparticles interact differently with light.


Nanotechnology in the Middle Ages

Depiction of a forest glass shop from Sir John Mandeville's Travels, Dated 1420 – 1450. British Library, London


Why Do We Care?

Nanotechnology can improve how we live!


60-100 nm

  • Silver nanoparticles are used to kill bacteria in:

  • Athletic apparel

  • Socks

  • Refrigerators

  • Storage containers

  • Washing machines

Gold nanoshells can target and destroy cancer cells


“Printing” Nano-solar Panels


Cities could be Power Plants!


Carbon Nanotube

Energy Transportation


Coal

Graphite

Diamond

Carbon Nanotube

Carbon Atoms Rearranged


But what about the risks?


Think Like a Nano Scientist!

True or False?

FALSE!

TRUE!

1. A red blood cell is

found on the nanoscale.

2. DNA is found on the nanoscale.


True or False?

TRUE!

TRUE!

2. Nanotechnology can effect the way we move and produce energy.

1. Things on the nanoscalecan be found all around us in nature.
