TL;DR: The structure of as-prepared carbon films, characterized by transmission electron microscopy, Raman spectra and x-ray photoelectron spectra, is considered as nanocomposite thin films with C60 and fullerene crystalline nanoparticles embedded in amorphous sp2 and sp3 carbon matrices as mentioned in this paper.
Abstract: Hydrogenated amorphous carbon films were deposited by dc-pulse plasma chemical vapor deposition. The structure of as-prepared films, characterized by transmission electron microscopy, Raman spectra, and x-ray photoelectron spectra, is considered as nanocomposite thin films with C60 and fullerene crystalline nanoparticles embedded in amorphous sp2 and sp3 carbon matrices. The high hardness and high elastic recovery of as-prepared films are attributed to the unique structure that C60 and fullerene nanocrystalline grains (soft) dispersed in amorphous carbon phase (hard) to form a network structure, which restrains the dislocation migration, assists the stress relaxation, and hence, enhances the mechanical properties of the films.

TL;DR: These insoluble, redox-active polymers have potential utility for the adsorption of various gases, for the construction of capacitors, for sensing, forThe preparation of metal-containing heterofullerenes, and for catalysis.
Abstract: In this review, we examined the interactions of metal complexes and metal surfaces with fullerenes. That information has been related to the formation of redox-active materials produced by electrochemical reduction of solutions of various transition metal complexes and fullerene or fullerene adducts. These redox-active polymers are strongly bound to electrode surfaces and display electrochemical activity in solutions containing only supporting electrolyte. Extensive studies of the electrochemical behavior of these films have been used to characterize their properties and structure. The process that produces these poly-PdnC60 and poly-PtnC60 films can also produce composite materials that consist of metal nanoparticles interspersed with the poly-PdnC60 and poly-PtnC60 materials. The relationship between these redox-active films and conducting metal organic framework materials has been examined. These insoluble, redox-active polymers have potential utility for the adsorption of various gases, for the constr...

TL;DR: It is reported that the surface hydroxylation of C60 molecules is the most likely mechanism for pristine C60 fullerenes/C60 fulLErene aggregate stabilization in water, being independent of the method of C 60 fullerene aqueous solution preparation.

TL;DR: The Langmuir-Blodgett (LB) films of the fullerene (C[sub 60]) were formed with and without matrix molecules, as observed by atomic force microscopy (AFM).
Abstract: The Langmuir-Blodgett (LB) films of the fullerene (C[sub 60]) were formed with and without matrix molecules. The pure C[sub 60] formed a collapsed film at the air-water interface. The surface of the transferred film was inhomogeneous, as observed by atomic force microscopy (AFM). The monolayers of a 1:1 mixture with icosanoic acid were transferred onto substrates with good quality. The LB films had a smooth surface composed of a mixture of C[sub 60] and icosanoic acid dispersed with flat microcrystals of C[sub 60] observed by AFM. The 1:1 mixture with dioctadecyldimethylammonium perchlorate was deposited as Z-type film onto the substrates. The absorption spectra of both of the mixed films were in good agreement with those of evaporated films. These films will be precursors of the molecular systems utilizing the peculiar properties of fullerenes and fullerene anions. 13 refs., 4 figs.
