Abstract
A method of making a porous membrane is disclosed. One such method optionally includes: forming a plurality of pillars in an array form over a substrate; and forming a layer with a mixture of a porous material precursor and a surfactant over the substrate. The method optionally includes removing the pillars to leave cavities in the layer; filling the cavities in the layer with a cavity filler; and removing the surfactant from the layer. The porous membrane can be used as, for example, a sieve for separating molecules from a chemical reaction.

1-34. (canceled)
An apparatus comprising:
- a first layer having a thickness between about 100 nm to about 1 μm, the first layer including a plurality of first pores having a first diameter between about 2 nm and about 50 nm, wherein the plurality of first pores permit fluid and/or molecules having a diameter smaller than the first diameter to pass through the first layer;
- and
- a second layer attached to the first layer, the second layer including one or more second pores having a second diameter greater than the first diameter, wherein the one or more second pores are aligned to permit the fluid and/or molecules to pass from the first layer through the second layer.
An apparatus comprising:
- a first layer having a thickness between about 100 nm to about 1 μm, the first layer including a plurality of first pores having a first diameter between about 2 nm and about 50 nm, wherein the plurality of first pores permit fluid and/or molecules having a diameter smaller than the first diameter to pass through the first layer, and wherein the first layer comprises calcine.
