The present invention provides templating methods for replicating patterned metal films from a template substrate such as for use in plasmonic devices and metamaterials. Advantageously, the template substrate is reusable and can provide plural copies of the structure of the template substrate. Because high-quality substrates that are inherently smooth and flat are available, patterned metal films in accordance with the present invention can advantageously provide surfaces that replicate the surface characteristics of the template substrate both in the patterned regions and in the unpatterned regions.

Replication of patterned thin-film structures for use in plasmonics and metamaterials

Methods and reactors for producing a fuel are disclosed herein. In some embodiments, the method uses a biomass feedstock and alkane and/or alcohol feedstock, which can be contacted with a metal-containing catalyst to form products including a bio-oil. In some embodiments, oxygen-containing functional groups can be removed from a bio-oil using one or more zeolite thin films.
