Abstract:
Detectors and methods of forming the same include aligning a semiconducting carbon nanotubes on a substrate in parallel to form a nanotube layer (208). The aligned semiconducting carbon nanotubes in the nanotube layer are cut to a uniform length corresponding to a detection frequency (216). Metal contacts are formed at opposite ends of the nanotube layer (218).
Abstract:
Provided herein is a nanopore structure, which in one aspect is a "carbon nanotube porin", that comprises a short nanotube with an associated lipid coating. Also disclosed are compositions and methods enabling the preparation of such nanotube/lipid complexes. Further disclosed is a method for therapeutics delivery that involves a drug delivery agent comprising a liposome with a NT loaded with a therapeutic agent, introducing the therapeutic agent into a cell or a tissue or an organism; and subsequent release of the therapeutic agents into a cell.
Abstract:
In some embodiments, the present invention relates to new processes to simultaneously shorten and functionalize raw or purified carbon nanotubes to improve their dispersity and processibility, and the short functionalized nanotubes that may be made by the processes. This present invention also relates to new compositions of matter using short functionalized carbon nanotubes with thermoset, thermoplastic polymers, high temperature polymers, and other materials; the processes for making such composite materials; and the products of said processes.
Abstract:
According to some embodiments, the present invention provides a method for attaining short carbon nanotubes utilizing electron beam irradiation, for example, of a carbon nanotube sample. The sample may be pretreated, for example by oxonation. The pretreatment may introduce defects to the sidewalls of the nanotubes. The method is shown to produces nanotubes with a distribution of lengths, with the majority of lengths shorter than 100 tun. Further, the median length of the nanotubes is between about 20 nm and about 100 nm.
Abstract:
The present invention is directed towards methods (processes) of providing large quantities of carbon nanotubes (CNTs) of defined diameter and chirality (i.e., precise populations). In such processes, CNT seeds of a pre-selected diameter and chirality are grown to many (e.g., hundreds) times their original length. This is optionally followed by cycling some of the newly grown material back as seed material for regrowth. Thus, the present invention provides for the large-scale production of precise populations of CNTs, the precise composition of such populations capable of being optimized for a particular application (e.g., hydrogen storage). The present invention is also directed to complexes of CNTs and transition metal catalyst precurors, such complexes typically being formed en route to forming CNT seeds.
Abstract:
A method of producing a molecular structure comprises determining a desired shape of the molecular structure; providing a multi-layer structure, the multilayer structure having at least first and second adjacent generally planar molecular layers, the first and second generally planar molecular layers each consisting of an array of covalently bonded atoms; arranging the multi-layer structure in a desired orientation relative to a cutter; using the cutter to break bonds within the first generally planar molecular layer to produce a first edge of a desired configuration corresponding to the desired shape of the molecular structure; and using the cutter to break bonds within the second generally planar molecular layer to produce a second edge of a desired configuration corresponding to the desired shape of the molecular structure; and allowing the first edge of the first generally planar molecular layer and the second edge of the second generally planar molecular layer to relax so that the first edge of the first generally planar molecular layer and the second edge of the second generally planar molecular layer covalently bond to one another.
