Three Dimensionally Interlinked, Dense, Solid Form of Single-Walled CNT Ropes
Read More >>
The nanotube block has high mechanical strength and resistance to indentation.
A 3D networked, dense form of single-walled carbon nanotubes (SWNT) has been made through isotropic shrinking of a gel-like SWNT-water paste by very slow evaporation. Approximately 35 g of Raw HiPco nanotubes were cleaned by the method of ...Read More >>
Flexible Plug Repair for Shuttle Wing Leading Edge
Read More >>
Thin, flexible plugs conform to surfaces.
In response to the Columbia Accident Investigation Board report, a plug repair kit has been developed to enable astronauts to repair the space shuttle’s wing leading edge (WLE) during orbit. The plug repair kit consists of several 17.78-cm-diameter carbon/ silicon carbide (...Read More >>
Use of Functionalized Carbon Nanotubes for Covalent Attachment of Nanotubes to Silicon
Read More >>
This method enables the introduction of carbon nanotubes onto all types of silicon-based devices and silicon surfaces.
The purpose of the invention is to covalently attach functionalized carbon nanotubes to silicon. This step allows for the introduction of carbon nanotubes onto all manner of silicon surfaces, and thereby ...Read More >>
