Lamellar doubling

The model has been successfully used to describe wetting behavior of the microemulsion at the oil-water interface [12,18-20], to investigate a few ordered phases such as lamellar, double diamond, simple cubic, hexagonal, or crystals of spherical micelles [21,22], and to study the mixtures containing surfactant in confined geometry [23].

The term "anionic clay" is used to designate synthetic or natural lamellar hydroxides with interlayer domains containing anionic species. This designation refers to the more usual "cationic clays" whose interlamellar domains contain cationic species. The more structural designation of "Lamellar Double Hydroxides" (LDHs) has been used in the last few years (Martin and Pinnavaia 1986) and account for the presence of two kinds of metallic cations in the... 

Lamellar double hydroxides are part of, or are precursors of, a more general family of compounds designated as pillared layered structures (PLS). We quote some terms used to describe them (Mitchell 1990 Van Damme 1990). Pillared Layered Structures are nanocomposite materials prepared by linking molecules or colloids to a layered host. They exhibit a remarkably broad spectrum of structural, chemical, electronic, ionic, optical and magnetic properties, and provide supermesh host structures in which chemical reactions or physical processes can proceed under gas-phase conditions, but at liquid/solid state densities. They can be shaped as powders, pellets, or supported or self-standing Aims, and can be dispersed in solid or liquid matrices.
