About the possibility of applying empirical methods of estimation of standard enthalpies of formation of organic compound for fullerenes

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2023
Due to the high practical significance and, as a consequence, active study of carbon nanomaterials, the question of methods for investigating their physicochemical, in particular, thermodynamic properties is relevant.

Matching Polynomial-Based Similarity Matrices and Descriptors for Isomers of Fullerenes

open access: yesInorganics, 2023
I have computed the matching polynomials of a number of isomers of fullerenes of various sizes with the objective of developing molecular descriptors and similarity measures for isomers of fullerenes on the basis of their matching polynomials.

Methodological Investigation for Hydrogen Addition to Small Cage Carbon Fullerenes

open access: yesCrystals, 2021
Hydrogenated small fullerenes (Cn, n < 60) are of interest as potential astrochemical species, and as intermediates in hydrogen-catalysed fullerene growth.

Unique Crystallization of Fullerenes: Fullerene Flowers [PDF]

open access: yesScientific Reports, 2016
AbstractSolution-phase crystallization of fullerene molecules strongly depends on the types of solvent and their ratios because solvent molecules are easily included in the crystal lattice and distort its structure. The C70(solute)–mesitylene (solvent) system yields crystals with various morphologies and structures, such as cubes, tubes, and imperfect ...

The Generation of Fullerenes [PDF]

open access: yes, 2012
We describe an efficient new algorithm for the generation of fullerenes. Our implementation of this algorithm is more than 3.5 times faster than the previously fastest generator for fullerenes -- fullgen -- and the first program since fullgen to be ...

Magnetic silicon fullerene [PDF]

open access: yesPhysical Chemistry Chemical Physics, 2010
A metal-encapsulating silicon fullerene, Eu@Si20, has been predicted by density functional theory to be by far the most stable fullerene-like silicon structure. The Eu@Si20 structure is a dodecahedron with D2h symmetry in which the europium atom occupies the center site.

Fullerenes, PAHs, Amino Acids and High Energy Astrophysics

open access: yesActa Polytechnica CTU Proceedings, 2014
We present theoretical, observational and laboratory work on the spectral properties of fullerenes and hydrogenated fullerenes. Fullerenes in its various forms (individual, endohedral, hydrogenated, etc.) can contribute to the UV bump in the extinction ...
