    摘要: Techniques and assemblies for light ray steering are described. A method includes receiving solar rays onto a surface of an electro-optic prism. The electro-optic prism includes a first electrode positioned on a first substrate, a second electrode positioned on a second substrate, and an electro-optic material positioned between the first and second electrodes. The first electrode includes multiple substantially parallel linear electrodes. The method further includes applying multiple voltages to some or all of the substantially parallel linear electrodes to generate a refractive index gradient across the electro-optic prism. The method further includes controlling the refractive index gradient so that the solar rays exit the electro-optic prism in a direction substantially normal to a light focusing element, and utilizing the light focusing element to focus the solar rays on a solar energy collector.

    摘要: The present invention is directed to the creation of macroscopic materials and objects comprising aligned nanotube segments. The invention entails aligning single-wall carbon nanotube (SWNT) segments that are suspended in a fluid medium and then removing the aligned segments from suspension in a way that macroscopic, ordered assemblies of SWNT are formed. The invention is further directed to controlling the natural proclivity of nanotube segments to self assemble into ordered structures by modifying the environment of the nanotubes and the history of that environment prior to and during the process. The materials and objects are “macroscopic” in that they are large enough to be seen without the aid of a microscope or of the dimensions of such objects. These macroscopic, ordered SWNT materials and objects have the remarkable physical, electrical, and chemical properties that SWNT exhibit on the microscopic scale because they are comprised of nanotubes, each of which is aligned in the same direction and in contact with its nearest neighbors. An ordered assembly of closest SWNT also serves as a template for growth of more and larger ordered assemblies. An ordered assembly further serves as a foundation for post processing treatments that modify the assembly internally to specifically enhance selected material properties such as shear strength, tensile strength, compressive strength, toughness, electrical conductivity, and thermal conductivity.

    摘要: Single-walled carbon nanotubes have been synthesized by the catalytic decomposition of both carbon monoxide and ethylene over a supported metal catalyst known to produce larger multi-walled nanotubes. Under certain conditions, there is no termination of nanotube growth, and production appears to be limited only by the diffusion of reactant gas through the product nanotube mat that covers the catalyst The present invention concerns a catalyst-substrate system which promotes the growth of nanotubes that are predominantly single-walled tubes in a specific size range, rather than the large irregular-sized multi-walled carbon fibrils that are known to grow from supported catalysts. With development of the supported catalyst system to provide an effective means for production of single-wall nanotubes, and further development of the catalyst geometry to overcome the diffusion limitation, the present invention will allow bulk catalytic production of predominantly single-wall carbon nanotubes from metal catalysts located on a catalyst supporting surface.

    摘要: Techniques and assemblies for light ray steering are described. A method for directing light rays includes steering the light rays using a static prism and controllably steering the light rays using an electro-optic prism, such that the combination of the light ray steerings from the static prism and the electro-optic prism substantially steer the light rays to impinge on a light focusing element at a predetermined angle. The electro-optic prism includes a first electrode positioned on a first substrate, a second electrode positioned on a second substrate, and an electro-optic material positioned between the first and second electrodes. The first electrode includes multiple substantially parallel linear electrodes. Applying multiple voltages to some or all of the multiple substantially parallel linear electrodes generates a refractive index gradient across the electro-optic prism. The direction of solar rays exiting the electro-optic prism is controllable by controlling the refractive index gradient. The method further includes receiving the light rays at the light focusing element and focusing the light rays, after the light rays have passed through the static prism and the electro-optic prism.
