Extremal fullerene graphs with the maximum Clar number [PDF]

open access: yes, 2009
A fullerene graph is a cubic 3-connected plane graph with (exactly 12) pentagonal faces and hexagonal faces. Let $F_n$ be a fullerene graph with $n$ vertices.

Fullerene van der waals Oligomers as electron traps [PDF]

open access: yes, 2014
Density functional theory calculations indicate that van der Waals fullerene dimers and larger oligomers can form interstitial electron traps in which the electrons are even more strongly bound than in isolated fullerene radical anions.

Raman Laser Polymerization of C60 Nanowhiskers

open access: yesJournal of Nanotechnology, 2012
Photopolymerization of C60 nanowhiskers (C60NWs) was investigated by using a Raman spectrometer in air at room temperature, since the polymerized C60NWs are expected to exhibit a high mechanical strength and a thermal stability.

Chemistry of Fullerene Epoxides: Synthesis, Structure, and Nucleophilic Substitution-Addition Reactivity

open access: yesMolecules, 2012
Fullerene epoxides, C<sub>60</sub>O<sub>n</sub>, having epoxide groups directly attached to the fullerene cage, constitute an interesting class of fullerene derivatives.

Co-exposure of the organic nanomaterial fullerene C60 with benzo[a]pyrene in Danio rerio (zebrafish) hepatocytes: Evidence of toxicological interactions [PDF]

open access: yes, 2013
Compounds from the nanotechnology industry, such as carbon-based nanomaterials, are strong candidates to contaminate aquatic environments because their production and disposal have exponentially grown in a few years.

Fullerene Black: Relationship between Catalytic Activity in n-alkanes Dehydrocyclization and Reactivity in Oxidation, Bromination and Hydrogenolysis

open access: yesEurasian Chemico-Technological Journal, 2001
The reactivity of fullerene black in oxidation (by air oxygen or ions MnO4–or Cr2O7 2– in solution), bromination (by Br2 or (C4H9)4NBr3) and hydrogenolysis (without hydrogenation catalyst) are studied.

The readout of the fullerene-based quantum computing by a scanning tunneling microscope [PDF]

open access: yes, 2006
We consider to detect the electron spin of a doped atom, i.e., a nitrogen or a phosphorus, caged in a fullerene by currently available technique of the scanning tunneling microscope (STM), which actually corresponds to the readout of a qubit in the ...

Fullerenes as polyradicals [PDF]

open access: yesFuture Generation Computer Systems, 2004
Abstract We present the investigation of the electronic structure of X60 molecules (X=C, Si), containing 60 odd electrons with spin-dependent interaction between them. Conditions for the electrons to be excluded from the covalent pairing are discussed.

Fullerenes: Characteristics of the substance, biological effects and occupational exposure levels

open access: yesMedycyna Pracy, 2016
Fullerenes are molecules composed of an even number of carbon atoms of a spherical or an ellipsoidal, closed spatial structure. The most common fullerene is the C60 molecule with a spherical structure – a truncated icosahedron, compared to a football ...

Effect of self-assembly of fullerene nano-particles on lipid membrane. [PDF]

open access: yesPLoS ONE, 2013
Carbon nanoparticles can penetrate the cell membrane and cause cytotoxicity. The diffusion feature and translocation free energy of fullerene through lipid membranes is well reported.
