摘要: A scintillation device includes a free-standing ceramic scintillator body that includes a polycrystalline ceramic scintillating material comprising a rare earth element, wherein the polycrystalline ceramic scintillating material is characterized substantially by a cation-deficient perovskite structure. A method of producing a free-standing ceramic scintillator body includes preparing a precursor solution including a rare earth element precursor, a hafnium precursor and an activator (Ac) precursor, obtaining a precipitate from the solution, and calcining the precipitate to obtain a polycrystalline ceramic scintillating material including a rare earth hafnate doped with the activator and having a cation-deficient perovskite structure.

摘要: A composite oxygen transport membrane having a dense layer, a porous support layer and an intermediate porous layer located between the dense layer and the porous support layer. Both the dense layer and the intermediate porous layer are formed from an ionic conductive material to conduct oxygen ions and an electrically conductive material to conduct electrons. The porous support layer has a high permeability, high porosity, and a microstructure exhibiting substantially uniform pore size distribution as a result of using PMMA pore forming materials or a bi-modal particle size distribution of the porous support layer materials. Catalyst particles selected to promote oxidation of a combustible substance are located in the intermediate porous layer and in the porous support adjacent to the intermediate porous layer. The catalyst particles can be formed by wicking a solution of catalyst precursors through the porous support toward the intermediate porous layer.
