LamellarLαMesophases Doped with Inorganic Nanoparticles

Lamellar Lα mesophases doped with inorganic nanoparticles.

The development of nanostructured hybrid systems is a flourishing area of research, which brings together chemistry, physics and materials science. These systems are composed of nanoparticles with interesting properties (e.g. optical, magnetic, catalytic) dispersed within an organic matrix. Control of both the position and orientation of the particles in a precise and reproducible way is an imp...

Colouring crystals with inorganic nanoparticles.

A simple, one-pot method is presented whereby gold nanoparticles coated with a zwitterionic diblock copolymer are incorporated within single crystals of calcite. This may provide a versatile alternative to dyeing crystal with organic molecules and could be extended to create a series of new nanocomposite crystals with novel properties.

Rare Earth Doped Nanoparticles in Organic and Inorganic Host Materials for Application in Integrated Optics

The preparation and the optical properties of lanthanum fluoride (LaF3) nanoparticles doped with erbium and neodymium will be discussed. Organic and inorganic materials in the form of polymers and sol-gels were used to serve as the hosts for the inorganic nanoparticles, respectively. The organic host material has been synthesized such that it is photo-crosslinkable to facilitate straightforward...

Liquid crystals doped with magnetic nanoparticles

The paper presents an overview of the observations of structural transitions in ferronematics based on thermotropic nematics 4-cyano-4'octylbiphenyl (8CB) and 4-trans-4’-n-hexyl-cyclohexyl-isothiocyanato-benzene (6CHBT). The determination of the surface density of anchoring energy of nematic molecules on magnetic particles surfaces by the observations of the structural transitions in external f...
