Abstract:
Processes for making multinary bulk and thin film alloys with nanometer-scale grains are disclosed. An electroless process includes contacting a substrate with a bath within a sealed pressure vessel; and heating the sealed pressure vessel for a time and at a temperature under an autogeneous pressure effective for plating a film of an alloy with nanometer-scale grains onto a contacted portion of the substrate; wherein the bath is formed from one or more salts comprising each constituent element of the alloy, an organic medium, and a reducing agent. The bulk and thin film alloys may be useful in applications requiring high surface area materials or protection from corrosion such as for catalysts and battery cathodes.
Abstract:
Nanowires, films, and membranes comprising ordered porous manganese oxide-based octahedral molecular sieves, and methods of making, are disclosed. A single crystal ultra-long nanowire includes an ordered porous manganese oxide-based octahedral molecular sieve, and has an average length greater than about 10 micrometers and an average diameter of about 5 nanometers to about 100 nanometers. A film comprises a microporous network comprising a plurality of single crystal nanowires in the form of a layer, wherein a plurality of layers is stacked on a surface of a substrate, wherein the nanowires of each layer are substantially axially aligned. A free standing membrane comprises a microporous network comprising a plurality of single crystal nanowires in the form of a layer, wherein a plurality of layers is aggregately stacked, and wherein the nanowires of each layer are substantially axially aligned.
