Abstract: A process for functionalizing a carbon surface and the product thereof is disclosed. The first reactant used contains one or more electron withdrawing groups that thereafter can be reacted with other compounds. The reaction product has enhanced dispersability, interaction with other media, or other utilitarian uses, e.g. a reactive surface. The reaction product is then incorporated into an elastomeric or thermoplastic composition; it can be dispersed in a liquid media such as an ink, coating, or lubricant; or it can be used as a solid in applications such as a filtering media.

Abstract: This invention is directed to security features that are formed, created, printed from inks comprising metallic particles and/or metallic nanoparticles. Preferably, the security feature is a reflective security features that comprises metallic nanoparticles where the reflective security features are formed by a direct-writing process, e.g., an ink jet printing process, using an ink comprising metallic nanoparticles. The invention is also directed to the use of these security features in many applications and to processes for making them.

Abstract: Multi-component particles comprising inorganic nanoparticles distributed in an organic matrix and processes for making and using same. A flowing aerosol is generated that includes droplets of a precursor medium dispersed in a gas phase. The precursor medium contains a liquid vehicle and at least one precursor. At least a portion of the liquid vehicle is removed from the droplets of precursor medium under conditions effective to convert the precursor to the nanoparticles or the matrix and form the multi-component particles.

Abstract: A structured fluid composition comprising: (a) a low refractive index liquid; (b) particles including light absorbing charged particles such as pigments, non-light absorbing uncharged particles such as teflon, silica, alumina and combinations thereof; and (c) at least one additive selected from the group consisting of a dispersant, a charging agent, a surfactant, a flocculating agent, a polymer, and combination thereof; for use in a TIR electronic display. The inventive composition improves the long-term stability, response time and visible appearance of image displays which electrophoretically frustrate total internal reflection (TIR).
