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
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
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
What are its properties? • High specific surface area (100-500m2/g) • Electrically conductive! • Enhanced catalytic activity • Surprisingly capable thermal insulator http://www.aerogel.org/wp-content/uploads/cache/d07f9ffdc3be0bf80ec6052422ce9771.jpg
How is metal aerogel made? Combustion synthesis Dealloying Nanosmelting http://www.aerogel.org/wp-content/uploads/2009/03/fenanofoamproduction-lanl1.jpg
Applications • Hydrogen storage • Antimicrobial scaffolds • Magnetic media • X-Ray optics http://www.greenpacks.org/wp-content/uploads/2008/06/honda-fcx-clarity.jpg
