  • Publication number: 20120097521
    Abstract: Nanostructured arrays having a metal catalyst (e.g., cobalt) are irradiated with light to initiate the an artificial photosynthetic reaction resulting in the formation of carbon-containing molecules, for example, long chained hydrocarbons or amino acids. A nanostructure having one or more structural elements having a high aspect ratio can formed over a substrate and are placed in contact with water and a carbon-containing source (e.g., carbon dioxide, bicarbonate, methane). When the nanostructure is exposed to light, the water and the carbon-containing source can react to form a molecule having at least two carbon atoms chained together. Structural elements may include a number of metal layers arranged in a patterned configuration so that, upon light irradiation, a greater amount of light energy is concentrated in close proximity to the region where the reaction is catalyzed than for the case without the patterned configuration.

  • Publication number: 20120028267
    Abstract: Disclosed is a method of detecting even a very small amount of a target substance by mixing a linker and a spacer at a suitable ratio and immobilizing the mixture on the surface of carbon nanotubes in a carbon nanotube-based biosensor. This method detects a specific substance at the level of femtomoles and lowers the detection limit of conventional carbon nanotube transistor sensors. Accordingly, the method detects even a very small amount of a target substance, and thus the carbon nanotube-based biosensor is a highly useful sensor which can be used either as a medical sensor for diagnosing diseases or as an environmental sensor.

  • Patent number: 7834468
    Abstract: A plurality of semiconductor nanoparticles having an elementally passivated surface are provided. These nanoparticles are capable of being suspended in water without substantial agglomeration and substantial precipitation on container surfaces for at least 30 days. The method of making the semiconductor nanoparticles includes reacting at least a first reactant and a second reactant in a solution to form the semiconductor nanoparticles in the solution. A first reactant provides a passivating element which binds to dangling bonds on a surface of the nanoparticles to passivate the surface of the nanoparticles. The nanoparticle size can be tuned by etching the nanoparticles located in the solution to a desired size.

  • Patent number: 7695993
    Abstract: A method can be adapted for design and preparation of a matrix nanocomposite sensing film for hydrogen sulphide SAW/BAW detection at room temperature. A matrix nanocomposite can be synthesized by incorporating both single-wall and multi-wall thiolated carbon nanotubes into conductive organic polymers or ceramic nanocrystalline in a properly functionalized manner. A thin organic sensing film can be prepared based on the matrix nanocomposite. The matrix nanocomposite sensing film can be prepared on a surface of a SAW/BAW device by an additive process or a direct printing process. Finally, the sensing film can be consolidated by thermal annealing or laser annealing under ambient conditions in order to obtain the stable sensing film with higher sensitivity and electrical properties for a SAW/BAW based H2S sensor.

  • Patent number: 7378074
    Abstract: A carbon nanotube suspension uses water as the basic solvent added with dispersant, stabilizer, coalescing aid, adhesion promoter, and a carbon nanotube. The basic solvent and the above solutes form a low viscosity solvent with carbon nanotube suspending therein. Therefore, the carbon nanotube suspension is formed to serve as a source material of the electron emission source of a field-emission display. That is, the carbon nanotube can be coated on a surface for forming the carbon nanotube electron-emission layer.

  • Patent number: 7371457
    Abstract: The present invention is for particulate compositions and methods for producing them that can absorb or scatter electromagnetic radiation. The particles are homogeneous in size and are comprised of a nonconducting inner layer that is surrounded by an electrically conducting material. The ratio of the thickness of the nonconducting layer to the thickness of the outer conducting shell is determinative of the wavelength of maximum absorbance or scattering of the particle. Unique solution phase methods for synthesizing the particles involve linking clusters of the conducting atoms, ions, or molecules to the nonconducting inner layer by linear molecules. This step can be followed by growth of the metal onto the clusters to form a coherent conducting shell that encapsulates the core.
