Publication number: 20150137548Abstract: A manual wheelchair having a tilt mechanism that allows a user positioned on the wheelchair to control the tilt angle of the wheelchair seat. The manual wheelchair has a base frame with arm rests that are fixed in position with respect to the base frame. The tilt mechanism includes a controller that is affixed to the manual wheelchair at a location proximate to one of the arm rests within the ready reach of the user and which can be manipulated by the user without assistance from a caregiver to allow the seat of the manual wheelchair to freely pivot about a pivot point such that the user can locate the seat at a desired tilt angle by pushing or pulling on the arm rest. A further manipulation of the controller allows the user to lock the seat in the desired tilt angle and remain in that angle.Type: ApplicationFiled: May 1, 2013Publication date: May 21, 2015Inventors: Carole Purdue, Christopher Dykes

Patent number: 8562935Abstract: 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.Type: GrantFiled: October 14, 2004Date of Patent: October 22, 2013Assignee: William Marsh Rice UniversityInventors: Robert H.

Patent number: 8158203Abstract: The present invention is directed toward methods of attaching or grafting carbon nanotubes (CNTs) to silicon surfaces. In some embodiments, such attaching or grafting occurs via functional groups on either or both of the CNTs and silicon surface. In some embodiments, the methods of the present invention include: (1) reacting a silicon surface with a functionalizing agent (such as oligo(phenylene ethynylene)) to form a functionalized silicon surface; (2) dispersing a quantity of CNTs in a solvent to form dispersed CNTs; and (3) reacting the functionalized silicon surface with the dispersed CNTs. The present invention is also directed to the novel compositions produced by such methods.Type: GrantFiled: May 6, 2005Date of Patent: April 17, 2012Assignee: William Marsh Rice UniversityInventors: James M.

Patent number: 8080199Abstract: The present invention is directed toward methods of crosslinking carbon nanotubes to each other using microwave radiation, articles of manufacture produced by such methods, compositions produced by such methods, and applications for such compositions and articles of manufacture. The present invention is also directed toward methods of radiatively modifying composites and/or blends comprising carbon nanotubes with microwaves, and to the compositions produced by such methods. In some embodiments, the modification comprises a crosslinking process, wherein the carbon nanotubes serve as a conduit for thermally and photolytically crosslinking the host matrix with microwave radiation.Type: GrantFiled: August 17, 2007Date of Patent: December 20, 2011Assignee: William Marsh Rice UniversityInventors: James M.

Patent number: 7939047Abstract: The present invention is directed to methods of separating carbon nanotubes (CNTs) by their electronic type (e.g., metallic, semi-metallic, and semiconducting). Perhaps most generally, in some embodiments, the present invention is directed to methods of separating CNTs by bandgap, wherein such separation is effected by interacting the CNTs with a surface such that the surface interacts differentially with the CNTs on the basis of their bandgap, or lack thereof. In some embodiments, such methods can allow for such separations to be carried out in bulk quantities.Type: GrantFiled: July 27, 2005Date of Patent: May 10, 2011Assignee: William Marsh Rice UniversityInventors: James M.

Publication number: 20090042136Abstract: The present invention is directed toward methods of attaching or grafting carbon nanotubes (CNTs) to silicon or other surfaces, wherein such attaching or grafting occurs via functional groups on either or both of the CNTs and silicon surface. The present invention is also directed to the novel compositions produced by such methods. Previous work by Applicants has demonstrated covalent attachment of arenes via aryldiazonium salts to Si (hydride passivated single crystal or poly Si; <111> or <100>, p-doped, n-doped or intrinsic), GaAs, and Pd surfaces. In the case of Si, this provides a direct arene-Si bond with no intervening oxide. Applicants have also reported on the use of aryldiazonium salts for the direct covalent linkage of arenes to single wall carbon nanotubes (SWNTs) where the nanotubes can exist either as bundles or individual structures (when surfactant-wrapped).Type: ApplicationFiled: May 6, 2005Publication date: February 12, 2009Inventors: James M.
