摘要:
The purpose of the present invention is to provide a hydrogen-releasing film and a hydrogen-releasing laminated film which are less susceptible to embrittling at an ambient operating temperature of an electrochemical element. This hydrogen-releasing film comprises a Pd—Ag alloy and is characterized in that the content of Ag in the Pd—Ag alloy is 20 mol % or higher.

Ultra-thin porous films are deposited on a substrate in a process that includes laying down an organic polymer, inorganic material or inorganic-organic material via an atomic layer deposition or molecular layer deposition technique, and then treating the resulting film to introduce pores. The films are characterized in having extremely small thicknesses of pores that are typically well less than 50 nm in size.

Described herein are coated glass or glass-ceramic articles having improved reflection resistance. Further described are methods of making and using the improved articles. The coated articles generally include a glass or glass-ceramic substrate and a nanoporous Si-containing coating disposed thereon. The nanoporous Si-containing coating is not a free-standing adhesive film, but a coating that is formed on or over the glass or glass-ceramic substrate.

A nanoporous network includes carbon nanotubes (CNTs) with the network having a pore size in a range from about 15 nm to about 35 nm. The nanoporous network can be coated, compressed, or any combination of these operations in the manufacture of various articles. A method of making a nanoporous network includes disposing a concentrated aqueous CNT solution in a mold, freezing the concentrated aqueous CNT solution, and subliming the frozen concentrated CNT solution in a vacuum chamber.

A multilayer porous membrane formed of an extrudable polymer is provided. The membrane is formed by co-extruding at least two compositions, each of which comprises a heated porogen and polymer while in contact with each other under conditions to minimize or prevent unstable interfacial flow between extruded layers. In a preferred embodiment, the two compositions are different such that the layers have a different average pore size.
