    摘要： A method for the formation of a membrane is described. A collection of substantially spherical particles formed from a selected material is contacted with at least one reactive material. The reactive material is cured or otherwise polymerized by various techniques, so that it forms a matrix that substantially surrounds and contains the particles. A portion of the particle material is then removed, so that the matrix contains a pattern of pores that are permeable to selected substances in solution. In some instances, the matrix is formed by an interfacial reaction between at least two reactive materials. Related filtration membranes are also described.

    摘要： A photoelectrochemical cell may include a cell housing defining an interior volume with a window affixed to the cell housing for allowing the passage of light into the interior volume of the cell. A polymeric film may be affixed within the interior volume defining an anterior compartment and a posterior compartment within the cell housing. A plurality of semiconductor particles embedded continuously within a through thickness of the polymeric film so that a first respective surface area of the plurality of semiconductor particles is exposed to the anterior portion of the cell and a second respective surface area of the plurality of semiconductor particles is exposed to the posterior portion of the cell. The membrane may be immersed within an electrolyte so that incident radiation on the semiconductor particles causes oxidation and reduction to occur within the cell to produce gaseous hydrogen and oxygen.
