Abstract: A method of separating carbon nanotubes having substantially the same diameter including the steps of: providing a sample of carbon nanotubes; separating individual nanotubes within the sample, and mixing with a solution comprising fibrous protein fibrils so that at least some individual nanotubes form a complex with the protein fibrils, and separating out those nanotubules which have formed a complex. Preferably the protein is collagen. The separated nanotubes can be used in the fields of electronics, medical and materials science.

Abstract: The invention relates to a composite material constituted by a microporous or mesoporous matrix and nanoparticles of metal or of metal oxide. The material being wherein the material of the matrix is either disordered, or ordered and optionally oriented, and wherein the nanoparticles are i) monodisperse in size when said matrix material is ordered and optionally oriented; ii) either monodisperse in size or of size identical to the size of the pores of the matrix material when said matrix material is disordered. The method of preparing the material consists in impregnating a microporous or mesoporous solid material with a solution of nanoparticle precursors, then in reducing the precursors within said material forming the matrix. Impregnation is performed under saturated vapor pressure and under reflux of the precursor solution, and reduction is performed radiolytically.

Abstract: The invention relates to a method of synthesizing high-temperature melting materials. More specifically the invention relates to a containerless method of synthesizing very high temperature melting materials such as carbides and transition-metal, lanthanide and actinide oxides, using an aerodynamic levitator and a laser. The object of the invention is to provide a method for synthesizing extremely high-temperature melting materials that are otherwise difficult to produce, without the use of containers, allowing the manipulation of the phase (amorphous/crystalline/metastable) and permitting changes of the environment such as different gaseous compositions.
