Abstract: Disclosed in certain embodiments are closed-cell metal oxide particles and methods of preparing the same. In at least one embodiment, a closed-cell metal oxide particle comprises a metal oxide matrix defining an array of closed-cells. Each closed-cell encapsulates a media-inaccessible void volume. The outer surface of the closed-cell metal oxide particle is defined by the array of closed-cells.

Abstract: Disclosed in certain embodiments are polymer compositions comprising a hybrid metal oxide particles and methods of preparing the same. In at least one embodiment, hybrid metal oxide particles comprise a continuous matrix of a first metal oxide having embedded therein an array of metal oxide particles comprising a second metal oxide. In at least one embodiment, the hybrid metal oxide particles are substantially non-porous.
