FULLERENES AND PROTO-FULLERENES IN INTERSTELLAR CARBON DUST [PDF]

open access: yesThe Astrophysical Journal, 2012
Laboratory spectra of hydrogenated amorphous carbon (HAC) particles prepared under a variety of conditions show spectral features at 7.05, 8.5, 17.4 and 18.9 m (1418, 1176, 575 & 529 cm-1) that have been associated with emission from C60 molecules.

Advances in ORR, OER, and HER of fullerenes and derivatives: From DFT calculations to experimental identification

open access: yesAdvanced Sensor and Energy Materials, 2023
Fullerenes are widely applied in the field of ORR, OER, and HER due to their well-defined molecular structures, excellent electron affinity potential that can be used to regulate the electronic structures when composited with other materials, the π-π ...

Superconductivity in the Fullerenes

open access: yesScience, 1991
Intramolecular vibrations strongly scatter electrons near the Fermi-surface in doped fullerenes. A simple expression for the electron-phonon coupling parameters for this case is derived and evaluated by quantum-chemical calculations. The observed superconducting transition temperatures and their variation with lattice constants can be ...

Recursive generation of IPR fullerenes [PDF]

open access: yes, 2015
We describe a new construction algorithm for the recursive generation of all non-isomorphic IPR fullerenes. Unlike previous algorithms, the new algorithm stays entirely within the class of IPR fullerenes, that is: every IPR fullerene is constructed by ...

Removing Homocoupling Defects in Alkoxy/Alkyl‐PBTTT Enhances Polymer:Fullerene Co‐Crystal Formation and Stability

open access: yesAdvanced Functional Materials, EarlyView.
PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

Tuning the interactions between electron spins in fullerene-based triad systems

open access: yesBeilstein Journal of Organic Chemistry, 2014
A series of six fullerene–linker–fullerene triads have been prepared by the stepwise addition of the fullerene cages to bridging moieties thus allowing the systematic variation of fullerene cage (C60 or C70) and linker (oxalate, acetate or terephthalate)

Ni-dispersed fullerenes: Hydrogen storage and desorption properties [PDF]

open access: yes, 2006
Our study shows that the H2 storage media using Ni-dispersed fullerenes could be viable alternatives to reversible hydrogen storage. It is demonstrated that a single Ni coated on the fullerene surface can store up to three H2 molecules.
