A device for separating liquids such as oil and water includes a hydrophobic and oleophilic mesh that allows oil to pass through while preventing water from passing through. The mesh can be fabricated simply from inexpensive materials by coating a mesh with a hydrophobic polymer.

An optical material system for nanopatterning is provided that includes one or more material systems having spectrally selective reversible and irreversible transitions by saturating one of the spectrally selective reversible transitions with an optical node retaining a single molecule in a configuration and exposing the single molecule to its spectrally irreversible transitions to form a pattern.

Patterning via optical-saturable transitions

The present invention relates to coated, absorbent, freestanding assemblies comprising inorganic nanowires, articles of manufacture comprising the same, processes of producing the same and methods of use thereof. The assemblies of this invention are useful in various applications, including removal of organics or hydrophobic materials, and waterproofing applications.

Absorbant superhydrophobic materials, and methods of preparation and use thereof

The present invention is directed to methods and materials for producing complements and reproductions of a master, including such preparation in a high throughput setting, using, inter-alia, liquid supramolecular nanostamping (LiSuNS).

Liquid supramolecular nanostamping (LiSuNS)

This invention provides a method for increasing the activity of catalysts. The method requires the introduction of the catalyst into nano-structured surfaces. The catalysts are introduced as functional groups in molecules forming a monolayer on a surface. A mixed monolayer of catalyst and inert molecules generates ordered domains of molecules on the surface. The catalyst is confined in regions of 0.5 nm to 3 nm in size and is surrounded by an inert material. The presence of such ordered domains that commensurate in size with the reactants, enhance the performance of the catalyst and increase the rate of the reaction.

Monolayer-coated surfaces as catalytic platforms for organic reactions

The present invention provides a method to eliminate undesired parallel conductive paths of nanogap devices for aqueous sensing. The method involves the electrical insulation of an electrode pair, except for the nanogap region wherein electrical response is measured. The magnitude of undesired ionic current in a measurement is reduced by two orders of magnitude. The process to accomplish the present invention is self-aligned and avoids fabrication complexity. The invention has a great potential in nanogap device applications.

Insulated nanogap devices and methods of use thereof

A photodetector is provided that includes a FET structure with a channel structure having one or more nanowire structures. Noble metal nanoparticles are positioned on the channel structure so as to produce a functionalized channel structure. The functionalized channel structure exhibits pronounced surface plasmon resonance (SPR) absorption near the SPR frequency of the noble metal nanoparticles.

Ultrafast and ultrasensitive novel photodetectors

A method of stamping of molecular patterns and/or devices based on the reversible self-assembly of molecules, particularly organic molecules is disclosed. This method is suitable for the stamping of almost any nanofabricated device and can be used to transferring a large amount of pattern information from one substrate to another at the same time.

Nanocontact printing

An article has a surface, at least a portion of which has a local radius of curvature of about 1000 nm or less. For example, the article may be a nanoparticle or a surface, a portion of which has a roughness characterized by a radius of curvature of about 1000 nm or less. A monolayer coating disposed on the surface includes a plurality of ligands organized into ordered domains having a characteristic size of less than or about equal to 10 nm.

Nanoparticles having sub-nanometer features

Disclosed are optical devices including one or more carbon nanotubes that can function as plasmon waveguides. The presently disclosed devices advantageously utilize the existence of surface plasmons on carbon nanotubes through the generation and transport of surface plasmon polaritons across the nanotubes. Also disclosed are methods for tuning the devices through particular formation parameters for the nanotubes and/or selection of particular substrate materials. Systems of the present invention can provide optical data concerning a sample, for instance via construction of an NSOM image, as well as topological date concerning a sample via construction of an AFM image. In one embodiment, the disclosed systems can provide simultaneous acquisition of optical images and topological images.
