Abstract

A method to prepare a thin ceramic or metallic solid-state composition comprising three phases: a material (A), a material (B), and pores, wherein the porous matrix of material (A) has a porosity gradient in the range of about 0% to about 80%, and wherein the pores are partially or completely filled with material (B). Various compositions and methods of use for the prepared composition are also disclosed.
