050008: Nano-layered Silicates with High Chemical Reactivity

The smectite family of layered silicate minerals, the so-called "swelling clays," have theoretical surface areas of 700 meters per gram or larger. However, accessing this surface area for important materials applications such as catalysis, adsorption, and polymer-clay nanocomposite formation is not readily achievable; the elementary one-nanometer...
