2. What is Aerogel? Is essentially the solid framework of a gel A class of porous, solid materials that exhibit extreme material properties http://winarco.com/wp-content/uploads/2009/08/aerogel-grass.jpg

3. Properties  Extremely low density  Very good thermal insulator  High specific surface area  Lowest dielectric constant http://www.aerogel.org/?p=891&px=%2FClassic+Aerogel+Photos%2Ftheflower-lbl.jpg

4. Introducing Metal Aerogels! Inorganic cousins of the more common Silica Aerogel Until very recently, Metal Aerogels did not exist! http://www.aerogel.org/wp-content/uploads/2009/03/fenanofoam-lanl.jpg

5. What are its properties?  High specific surface area (100- 500m 2 /g)  Electrically conductive!  Enhanced catalytic activity  Surprisingly capable thermal insulator http://www.aerogel.org/wp-content/uploads/cache/d07f9ffdc3be0bf80ec6052422ce9771.jpg

6. How is metal aerogel made? Combustion synthesis Dealloying Nanosmelting http://www.aerogel.org/wp-content/uploads/2009/03/fenanofoamproduction-lanl1.jpg
