Fullerene-Based Symmetry in Hibiscus rosa-sinensis Pollen
The fullerene molecule belongs to the so-called super materials. The compound is interesting due to its spherical configuration where atoms occupy positions forming a mechanically stable structure. We first demonstrate that pollen of Hibiscus rosa-sinensis has a strong symmetry regarding the distribution of its spines over the spherical grain. These spines form spherical hexagons and pentagons....
full textantiferromagnetic Heisenberg model on fullerene - type symmetry clusters
The si= 1 2 nearest-neighbor antiferromagnetic Heisenberg model is considered for spins sitting on the vertices of clusters with the connectivity of fullerene molecules and a number of sites n ranging from 24 to 32. Using the permutational and spin-inversion symmetries of the Hamiltonian, the low-energy spectrum is calculated for all the irreducible representations of the symmetry group of each...
full textPreferential separation of fullerene[84] from fullerene mixtures by encapsulation.
The encapsulation of fullerenes with a cyclotriveratrylene derivative, capable to self assemble into a dimer by means of three strong 4-ureidopyrimidinone quadruple hydrogen bonds is described. The system shows preference for C84, allowing its easy enrichment directly from fullerene mixtures.

It is necessary to generate the automorphism group of a chemical graph in computer-aided structure elucidation. An Euclidean graph associated with a molecule is defined by a weighted graph with adjacency matrix M = [dij], where for i≠j, dij is the Euclidean distance between the nuclei i and j. In this matrix dii can be taken as zero if all the nuclei are equivalent. Otherwise, one may introduce...
full textFullerene pipes
Single-wall fullerene nanotubes were converted from nearly endless, highly tangled ropes into short, open-ended pipes that behave as individual macromolecules. Raw nanotube material was purified in large batches, and the ropes were cut into 100- to 300-nanometer lengths. The resulting pieces formed a stable colloidal suspension in water with the help of surfactants. These suspensions permit a v...
full textBiological functions of fullerene*
Fullerene (C60) is known to ef®ciently generate singlet oxygen when irradiated with light. In spite of such an unique photodynamic nature, little has been studied on biological functions of C60. This paper describes a tumor-therapeutic trial of C60 based on the photoinduced generation of active oxygen. To achieve preferential accumulation of C60 in the tumor tissue, this water-insoluble drug wa...
