Synthesis and Structural Studies of Two Paramagnetic Metallofullerenes with Isomeric C72 Cage.
Inorganic Chemistry, 2019We synthesized and isolated two paramagnetic metallofullerenes of La@C72 and Y@C72 with different fullerene cages, which were characterized by electron paramagnetic resonance (EPR) spectroscopy and theoretical calculations. DFT calculations disclosed two

C72: Gestion des sarcomes phyllodes : Une étude rétrospective de 12 cas
African Journal of Oncology, 2022INTRODUCTION : Les sarcomes phyllodes sont rares. Il n'y a pas assez de données pour codifier la prise en charge. L'objectif était d'étudier les aspects cliniques et thérapeutiques et le devenir des patients après un suivi d'au moins de quatre ans et de contribuer ainsi au corpus limité de connaissances sur ces tumeurs.

Electronic and geometric structure of C72
Zeitschrift für Physik D Atoms, Molecules and Clusters, 1993Semi-empirical (MNDO) and ab-initio Hartree-Fock (3-21G) calculations on the structure and stability of C72 are reported. Though never isolated experimentally, C72 has been previously suggested to be a particularly stable fullerene based on simple Huckel molecular orbital ideas.

C72 (or C120) cluster growth from C36 (or C60) clusters
Journal of Molecular Structure: THEOCHEM, 2007Abstract We suggest fabricating larger clusters of equal size by dimerizing smaller ones, and performed molecular dynamics simulations with Brenner potential on C72 (or C120) cluster growth from C36 (or C60) clusters in He atmosphere at temperatures between 100 and 4000 K, showing that the resultant clusters may be dumbbell, pod or ball shape ...

Geometric and electronic structures of non-IPR metallofullerene La@C72
Journal of Molecular Structure: THEOCHEM, 2007Abstract The geometric and electronic structures of non-IPR metallofullerenes La@C 72 were studied using density functional theory. The geometric optimization show that among four possible configurations for La@C 72 , the most favorable endohedral position is off-center site along the C 2 axis in α plane pointing to the 5, 5 bond, the fusion of ...

C72 isomers: the IPR-satisfying cage is disfavored by both energy and entropy
Chemical Physics Letters, 2004Abstract Relative concentrations of seven isomeric C 72 cages (one species with isolated pentagons, two isomers with a pentagon–pentagon junction, a cage with a heptagon, a cage with two heptagons, and two isomers each with two pentagon–pentagon fusions) are computed using the Gibbs energy in a broad temperature interval.
