Abstract:
A technique for embedding a nanotube in a nanopore is provided. A membrane separates a reservoir into a first reservoir part and a second reservoir part, and the nanopore is formed through the membrane for connecting the first and second reservoir parts. An ionic fluid fills the nanopore, the first reservoir part, and the second reservoir part. A first electrode is dipped in the first reservoir part, and a second electrode is dipped in the second reservoir part. Driving the nanotube into the nanopore causes an inner surface of the nanopore to form a covalent bond to an outer surface of the nanotube via an organic coating so that the inner surface of the nanotube will be the new nanopore with a super smooth surface for studying bio-molecules while they translocate through the nanotube.

PROBLEM TO BE SOLVED: To provide a biobased cross-linked composition derived from organism, a method for producing the crosslinked composition, a structure prepared therefrom, a biobased printed wiring board using the above composition and a method for producing the above structure. SOLUTION: Biobased materials such as lignin, crop oils, wood resins, tannins, polysaccharides and combinations thereof are cross-linked, preferably using heat, a cross-linking agent, and an initiator. The materials fabricated have suitable characteristics for printed wiring boards. A glass fiber or biobased cloth is impregnated with an admixture of the biobased material cross-linking agent and initiator and the impregnated material is processed by conventional methods to produce a printed wiring board.

A filter includes a membrane having a plurality of nanochannels formed therein. Functionalized nanoparticles are deposited through self assembly onto surfaces defining the nanochannels so as to decrease the final diameter of the membrane. Methods for making and using the filter are also provided.
Abstract:
A method of forming a structure having selectively placed carbon nanotubes, a method of making charged carbon nanotubes, a bi-functional precursor, and a structure having a high density carbon nanotube layer with minimal bundling. Carbon nanotubes are selectively placed on a substrate having two regions. The first region has an isoelectric point exceeding the second region's isoelectric point. The substrate is immersed in a solution of a bi-functional precursor having anchoring and charged ends. The anchoring end bonds to the first region to form a self-assembled monolayer having a charged end. The substrate with charged monolayer is immersed in a solution of carbon nanotubes having an opposite charge to form a carbon nanotube layer on the self-assembled monolayer. The charged carbon nanotubes are made by functionalization or coating with an ionic surfactant.
Abstract:
The present invention provides a method for the selective placement of carbon nanotubes on a particular surface. In particular, the present invention provides a method in which self-assembled monolayers formed on an unpatterned or patterned metal oxide surface are used to attract or repel carbon nanotubes from a dispersion containing the same. In accordance with the present invention, the carbon nanotubes can be attracted to the self-assembled monolayers so as to be attached to the metal oxide surface, or they can be repelled by the self-assembled monolayers bonding to a predetermined surface other than the metal oxide surface containing the self-assembled monolayers.
Abstract:
Separation of carbon nanotubes or fullerenes according to diameter through non- covalent pi-pi interaction with molecular clips is provided. Molecular clips are prepared by Diels- Alder reaction of polyacenes with a variety of dienophiles. The pi-pi complexes of carbon nanotrubes with molecular clips are also used for selective placement of carbon nanotubes and fullerenes on substrates.
