Abstract: A novel integrated filter device for the concurrent capture, filtration or separation of particle, chemicals, vapors and or/gasses from liquid or solid flows. The device has a filtration macrostructure substrate and a thin film coating over the macrostructure substrate which allows for compact and efficient capture, filtration and separations. Device may serve as a platform for chemical reactions. The device minimized problems associated with traditional filters, chemical sorbents or reactors and provided for enhanced collection and analysis of target materials. The methodology for construction also allows for modular assembly in various arrangements including a stacked configuration. The devices may be used collaboratively and cooperatively with other collection and separation technologies.

Abstract: A method and porous multi-component material for the capture, separation or chemical reaction of a species of interest is disclosed. The porous multi-component material includes a substrate and a composite thin film. The composite thin film is formed by combining a porous polymer with a nanostructured material. The nanostructured material may include a surface chemistry for the capture of chemicals or particles. The composite thin film is coupled to the support or device surface. The method and material provides a simple, fast, and chemically and physically benign way to integrate nanostructured materials into devices while preserving their chemical activity.

Abstract: A system, sorbent formulations, methods of preparation, and methods are described that provide selective sorption and release of CO2 from CO2-containing gases such as syngas. The sorbent may include magnesium oxide (MgO) and a group-I alkali metal nitrate. The sorbent may also include a group-I alkali metal carbonate and/or a group-II alkaline-earth metal carbonate.

Abstract: Compositions are disclosed for storing and releasing hydrogen and methods for preparing and using same. These hydrogen storage and releasing materials exhibit fast release rates at low release temperatures without unwanted side reactions, thus preserving desired levels of purity and enabling applications in combustion and fuel cell applications.

Abstract: Solid-state ionic or electrochemical devices can depend critically on the proper formation of a dense, Gd-doped ceria (GDC) layer on a porous substrate. Devices and methods of the present invention are characterized by the formation of a transitional buffer layer, which is less than 10 microns thick and comprises GDC, located between the porous substrate and the dense GDC layer. The transitional buffer layer provides a practical way to form the dense GDC layer on the porous substrate without cracks in the GDC layer and without clogging the pores of the substrate.
