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.

Enumeration of a class of IPR hetero-fullerenes [PDF]

open access: yesJournal of the Serbian Chemical Society, 2010
Hetero-fullerenes are fullerenes in which some of the carbon atoms are replaced by other atoms. This paper uses the Pólya theorem to count the number of their possible positional isomers and chiral isomers. To do this, the computer algebra system GAP was

Harnessing cosmic carbon: anaerobic microbial responses to fullerenes under early Earth conditions

open access: yesFrontiers in Microbiology
Fullerenes of extra-terrestrial origin may have been accessible as carbon sources for anaerobic microorganisms on the early Earth. Very little is known about how anaerobic microorganisms respond to and use fullerenes and their soluble derivatives.

COMPARATIVE ANALYSIS OF TWO METHODS FOR SYNTHESIS OF FULLERENES AT DIFFERENT HELIUM PRESSURES [PDF]

open access: yes, 2021
The results of the effect of helium pressure in the chamber on the amount and composition of the produced fullerenes (C60, C70, etc.) synthesized in the arc plasma with graphite electrodes are presented. The findings obtained when the arc is powered by a

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 ...

On the restricted three-body model of the dynamical behaviour of masses of C70 fullerenes at the nanoscale

open access: yesHeliyon, 2022
The present study investigates the positions and stability of C70 fullerenes. Numerically, the positions and stability have been computed C70 fullerene at the nanoscale to show the effects of the parameters involved with the help of software MATHEMATICA.

Versatile fullerenes as sensor materials [PDF]

open access: yes, 2021
The last century outstanding discovery of fullerenes (or C60), as they are popularly called ‘buckyball’ structured molecules with icosahedral spherical structure, consists of 60 sp2-hybridized carbon atoms.

Fullerene and its applications: A review

open access: yesJournal of Indian Academy of Oral Medicine and Radiology, 2020
Fullerene molecules are composed entirely of carbon, in the form of a hollow sphere, ellipsoid, or tube. Fullerenes in the cylindrical form are called carbon nanotubes (CNTs) or buckytubes and fullerenes in the spherical form are referred to as ...
