A new general molecular coding Prolog program is used in theoretical studies of the properties of fullerene isomers and derivatives to identify the topological equivalence classes of atoms and bonds in C20-C60 fullerenes. The symmetry perception algorithm is based on an exhaustive search of a minimal code. During this search all canonical labeled mapping trees are generated, allowing constructi...

Fullerenes have been so far identified in a few rock types with unique geological history. One group of these finds is related to impacts of extraterrestrial bodies on Earth surface, strictly speaking the impact structure of Sudbury (Becker et al., 1994) and to events recorded from Permian/Triassic (Becker et al., 2001) and Cretaceous/Tertiary boundaries (Heymann et al., 1994). Generally two ba...

AIM To study the ability of fullerenes C(60) to catalyse the reactions of generation of reactive oxygen species (ROS) in water solution after photoexcitation and to affect the vitality of tumor cells in vitro. METHODS The number and vitality of cultured Ehrlich carcinoma cells or rat thymocytes were determined using tripane blue, ROS levels were registered using the methods of electron parama...

In a world where the scale of technology is continuously shrinking, from phones to cars to solar panels, nanotechnology is seeing a rise in applications. Recently, increased use of nanotechnology in the medical industry brought fullerenes, sometimes referred to as Buckyballs, to the forefront. Fullerenes are currently being developed by engineers to encapsulate a chemotherapeutic drug and deliv...

This paper is devoted to developing the structure of fullerene signatures. These structure results are then used to construct a complete catalog of fullerenes with ten or more symmetries. These fullerenes fall into 112 families. The Coxeter fullerenes, obtained by subdividing the faces of the icosahedron, form the prototype family. Like the Coxeter families, each family in the catalog is a one,...

A range of mono- and bis-functionalised fullerenes have been synthesised and inserted into single-walled carbon nanotubes. The effect of the size and shape of the functional groups of the fullerenes on the resultant 1D arrays formed within the nanotubes was investigated by high resolution transmission electron microscopy and X-ray diffraction. The addition of non-planar, sterically bulky chains...

Functionalized fullerenes with specific physicochemical properties have been developed for cancer diagnosis and therapy. Notably, metallofullerene is a new class of magnetic resonance imaging (MRI) contrast-enhancing agent, and may have promising applications for clinical diagnosis. Polyhydroxylated and carboxyl fullerenes have been applied to photoacoustic imaging. Moreover, in recent years, f...

Photosensitized electron-transfer processes of fullerenes hybridized with electron donating or other electron accepting molecules have been surveyed in this review on the basis of the recent results reported mainly from our laboratories. Fullerenes act as photo-sensitizing electron acceptors with respect to a wide variety of electron donors; in addition, fullerenes in the ground state also act ...

The results of recent investigation of fullerene–fullerene hydride system as a potential high capacity hydrogen storage option are presented. Theoretically, C60 fullerenes can reversibly store up to 7.7 wt.% hydrogen by forming fullerene hydride C60Hx. However, high temperature and pressure are currently required to enable hydrogen exchange in this system. For example, direct hydrogenation of f...
