    摘要： A ceramic structure having a scaffold with at least one opening and at least one porous filler material at least partially filling the at least one opening is described. The porous ceramic filler includes a plurality of pores. The pores have an average size in a range from about 2 nm to about 100 nm. The plurality of pores includes at least one pore architecture. For each pore architecture, the average pore size does not vary by more than about 100% when the average pore size is in a range from about 2 nm to about 50 nm, and the average pore size does not vary by more than about 50% when the average pore size is greater than about 50 nm. The plurality of pores includes at least two pore architectures when the porous filler material is silica. Also described is a method of making the ceramic structure.

    摘要： A structure includes a substantially non-conductive frame having an exterior surface. The structure defines a plurality of passages that open to the exterior surface. Mesoporous material is disposed in the plurality of passages and is supported therein by the frame. In a method for making a mesoporous nanocrystalline titania hybrid material, a templating agent, an acid, and a titania precursor is mixed into a template liquid. A frame that defines a plurality of passages is placed into the template liquid. A solvent is evaporated from the template liquid, thereby forming a titania gel encapsulating the templating agent. The gel is heated to remove substantially the templating agent from the non-conductive frame and the titania, thereby leaving a mesoporous titania material.

    摘要： A membrane structure is provided. The membrane structure includes a first layer having a plurality of pores; and a second layer disposed on, the first layer. The second layer has a plurality of unconnected pores. At least a portion of the plurality of unconnected pores of the second layer is at least partially filled with a filler such that the first layer is substantially free of the filler. At least a portion of the plurality of unconnected pores of the second layer is in fluid communication with at least one of the pores of the first layer. A method of making a membrane structure is provided. The method includes the steps of providing a first layer having a plurality of interconnected pores; disposing a second layer on the first layer, and filling at least a portion of the unconnected pores of the second layer with a filler such that the first layer is substantially free of the filler. Disposing a second layer includes depositing a metal layer on the first layer; and anodizing the metal layer to convert the metal layer into porous oxide layer.
