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.

Fullerenes’ Interactions with Plasma Membranes: Insight from the MD Simulations

open access: yesBiomolecules, 2022
Understanding the interactions between carbon nanoparticles (CNPs) and biological membranes is critically important for applications of CNPs in biomedicine and toxicology.

Fullerene derivatives and fullerene superconductors [PDF]

open access: yesJournal of Physics and Chemistry of Solids, 1993
Abstract A series of 1:1 C 60 cycloaddition adducts, C 60 A (A = anthracene, butadiene, cyclopentadiene and methylcyclopentadiene), has been synthesized. The products are cleanly separated and characterized by use of TGA, 1 H-NMR, IR, and mass spectrometry. Among these adducts, C 60 , (methylcyclopentadiene) showed the highest thermal stability and

Clar Structure and Fries Set of Fullerenes and (4,6)-Fullerenes on Surfaces

open access: yesJournal of Applied Mathematics, 2014
Fowler and Pisanski showed that the Fries number for a fullerene on surface Σ is bounded above by |V|/3, and fullerenes which attain this bound are exactly the class of leapfrog fullerenes on surface Σ.

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 ...

The impact of water-soluble C60 fullerenes on the development of acute colitis in rats

open access: yesБіологічні студії, 2017
Anti-inflammatory drugs are traditionally applied for the treatment of acute colitis of various etiologies. However, they have several disadvantages due to intestinal and extraintestinal complications and lowefficiency. Therefore, a search for new agents

Biogenic fullerenes?

open access: yesInternational Journal of Astrobiology, 2003
If the discoveries of C60 and C70 fullerenes in terrestrial hard rocks are real, then some of these may have formed in the solid state by dehydrogenation-driven ‘zip-up’ of C60Hn and C70Hm progenitors. At three sites of such fullerene discoveries the building blocks for these large molecules may have come from algal remains.

Fabrication Methods of Fullerenes. a Critical Review Méthodes de fabrication des fullerènes. Une étude critique

open access: yesOil & Gas Science and Technology, 2006
The industrial use of fullerenes will require a significant up-scaling of their production. The five actually known techniques are discussed : 1. The electric arc (Krätschmer-Huffman). 2. The vaporization of carbon by pulsed lasers. 3.
