Abstract:
Dynamics of charged fullerene in a surface layer of fullerite is studied under the influence of neutral or charged particles of the gas phase surrounding the fullerite material. The translational displacements of the nodes of the crystal lattice structure are determined by the equations of motion of the centers of mass of fullerenes. Central fullerene, which is described as a discrete set of sixty carbon atoms, plays a special role in the presented mathematical model. Angular oscillations and rotations of the central fullerene are described by the dynamic Euler equations. All other fullerenes

Abstract:
Carbon forms a large number of allotropic forms, one of which is fullerene. Fullerene is a convex closed polyhedron with carbon atoms at its vertices. The most common is fullerene, consisting of 60 carbon atoms and designated - C60. In turn, fullerenes are able to agglomerate, forming a molecular crystal - fullerite. In the interaction of fullerite C60 with a solid, it is possible to deposit on the surface of the body both whole fullerite and the fullerenes that form it. The interaction process in the C60 fullerite system - the substrate of a solid, and then on - the fullerite - substrate syst

We suggest a method for a strong increase in the internal energy of the material that does not lead to its destruction.

ABSTRACT It is possible that fullerene–polycyclic aromatic hydrocarbon (PAH) clusters or associations of fullerenes with PAHs contain a large fraction of interstellar fullerenes in the interstellar medium. Herein, we report the formation and photofragmentation behaviour of fullerene–PAH derivatives, fullerene/9-vinylanthracene (C16H12) and fullerene/9-methylanthracene (C15H12) cluster cations. Experiments are carried out using a quadrupole ion trap in combination with time-of-flight mass spectrometry in the gas phase. The results show that fullerene (C60)/9-vinylanthracene (e.g. [(C16H12)3C60]

Abstract:
Fullerenes are a new allotrope of carbon characterized by a closed-cage structure consisting of an even number of three-coordinate carbon atoms devoid of hydrogen atoms. This class was originally limited to closed-cage structures with 12 isolated five-membered rings, the rest being six-membered rings. Although it was recognized that existing organic ring nomenclature could be used for these structures, the resulting names would be extremely unwieldy and inconvenient for use. At the same time it was also recognized that established organic nomenclature principles could be used, or adapted, to p

The structures and stabilities of carbon fullerenes C n( n =20–94) are studied with tight-binding molecular dynamics in combination with a new scheme for generating energetically favorable fullerene networks. Magic numbers for fullerene formation energy are observed at n =60, 70 and 84. The experimental observation of the more abundant fullerenes is related to the fragmentation stabilities and chemical reactivities of the fullerenes obtained from our calculations.

Fullerene-based n-type charge-collecting materials have emerged as a solution to high-performance perovskite solar cells. However, their application to perovskite solar cells was limited in the device architecture and only a small amount of fullerene additives could be introduced to the device system, because of the immiscibility of the fullerene species with polar solvents. To overcome this, triethylene glycol monomethyl ether chain-attached fullerene derivatives are synthesized and applied to normal-type perovskite solar cells.

The band gaps of connected construction of fullerene molecules with ZnONTs gradually reduced by increasing the tube length, but were not sensitive to the tubes diameter. It is found tha

Therefore, they offer a nanosize reinforcement that is lightweight and hollow.

The 6–12 Lennard–Jones potential function and the continuum approximation, in which it is assumed that the atoms can be replaced with a uniform distribution across the surface of the molecules, are exploited to model the interaction energies between lithium atoms and spherical fullerenes. Thus, the total interaction energies can be approximated by applying surface integrations. The results show that for a lithium atom interacting inside a spherical fullerene, the interaction energies are
