Abstract: Composite membranes that are adapted for separation, purification, filtration, analysis, reaction and sensing. The composite membranes can include a porous support structure having elongate pore channels extending through the support structure. The composite membrane also includes an active layer comprising an active layer material, where the active layer material is completely disposed within the pore channels between the surfaces of the support structure. The active layer is intimately integrated within the support structure, thus enabling great robustness, reliability, resistance to mechanical stress and thermal cycling, and high selectivity. Methods for the fabrication of composite membranes are also provided.

Abstract: Energy devices such as energy conversion devices and energy storage devices and methods for the manufacture of such devices. The devices include a support member having an array of pore channels having a small average pore channel diameter and having a pore channel length. Material layers that may include energy conversion materials and conductive materials are coaxially disposed within the pore channels to form material rods having a relatively small cross-section and a relatively long length. By varying the structure of the materials in the pore channels, various energy devices can be fabricated, such as photovoltaic (PV) devices, radiation detectors, capacitors, batteries and the like.

Abstract: An electrochemical gas sensor, a method for making the sensor and methods for the detection of a gaseous species. The electrochemical gas sensor is a solid-state gas sensor that includes a solid polymer electrolyte. A working electrode is separated from a counter electrode by the solid polymer electrolyte. The sensor can include a multilaminate structure for improved detection properties, where electrode microbands are disposed within the solid polymer electrolyte.

Abstract: Membranes including anodic aluminum oxide structures that are adapted for separation, purification, filtration, analysis, reaction and sensing. The membranes can include a porous anodic aluminum oxide (AAO) structure having pore channels extending through the AAO structure. The membrane may also include an active layer, such as one including an active layer material and/or active layer pore channels. The active layer is intimately integrated within the AAO structure, thus enabling great robustness, reliability, resistance to mechanical stress and thermal cycling, and high selectivity. Methods for the fabrication of anodic aluminum oxide structures and membranes are also provided.

Abstract: A solid-state composition having the general formula CuxAnLyZ, where: A is CO or an olefin and n=0 or n>0; L is an electrically neutral ligand and O<y<0; and Z is an anion bearing a charge x-. The solid-state composition can advantageously adsorb CO or an olefin in the presence of water.
