    Abstract: Tritiated planar carbon forms and their production are provided. Methods are provided for the stoichiometrically controlled labeling of planar carbon forms capitalizing on normal flaws of carboxylic acids ubiquitously present in commercial preparations of these planar carbon forms. Alternative methods include generation of a metallated intermediate whereby a metal is substituted for hydrogen on the carbon backbone of a planar carbon form. The metalized intermediate is then reacted with a tritium donor to covalently label the planar carbon form. The tritiated planar carbon forms produced are useful, for example, for determination of a biological property or environmental fate of planar carbon forms.

  • Publication number: 20080296537
    Abstract: In a method for functionalizing a carbon nanotube surface, the nanotube surface is exposed to at least one vapor including at least one functionalization species that non-covalently bonds to the nanotube surface, providing chemically functional groups at the nanotube surface, producing a functionalized nanotube surface. A functionalized nanotube surface can be exposed to at least one vapor stabilization species that reacts with the functionalization layer to form a stabilization layer that stabilizes the functionalization layer against desorption from the nanotube surface while providing chemically functional groups at the nanotube surface, producing a stabilized nanotube surface. The stabilized nanotube surface can be exposed to at least one material layer precursor species that deposits a material layer on the stabilized nanotube surface.

  • Publication number: 20080215122
    Abstract: The present invention provides for a method to increase the triplet yield of a photosensitizer by the coupling to metal surface plasmons which leads to increased singlet oxygen generation by electric field enhancement or enhanced energy absorption of the photosensitizer. The extent of singlet oxygen enhancement can be tuned for applications in singlet oxygen based clinical therapy by modifying plasmon coupling parameters, such as metallic nanoparticle size and shape, photosensitizer/metallic nanoparticle distance, and the excitation wavelength of the coupling photosensitizer.

  • Publication number: 20080161589
    Abstract: An aluminum chelate-based latent curing agent capable of curing a thermosetting epoxy resin under the condition of relatively low temperature in a short period of time is provided. Furthermore, a method for manufacturing the latent curing agent is provided, in which the curing conditions of the aluminum chelate-based latent curing agent can be controlled relatively easily. The aluminum chelate-based latent curing agent is prepared by reacting an aluminum chelate agent with a silsesquioxane type oxetane derivative in the presence of a water insoluble or poorly water-soluble cellulose ether, whereby latency properties are imparted thereto. This latent curing agent contains a coating layer composed of the water insoluble or poorly water-soluble cellulose ether. Preferably, the surface is treated with an isocyanate compound.
