Mesomorphic ceramic films are fabricated over large areas by blade-coating of nematic lyotropic suspensions, followed by calcination. Lyotropic self-assembly of titania or ZnO nanorods by applying blade-coating shear force to a dispersion of the rods, followed by thermal treatment forms transparent ceramic films for applications such as large aperture inorganic waveplates for modifying the polarization state of incident light that have superior optical and mechanical properties

Porous metal oxide microspheres are prepared via a process comprising forming a liquid solution or dispersion of polydisperse polymer nanoparticles and a metal oxide; forming liquid droplets from the solution or dispersion; drying the liquid droplets to provide polymer template microspheres comprising polymer nanospheres and metal oxide; and removing the polymer nanospheres from the template microspheres to provide the porous metal oxide microspheres. The porous microspheres exhibit saturated colors and are suitable as colorants for a variety of end-uses.
