Searching for stable fullerenes in space with computational chemistry

open access: yes, 2019
We report a computational study of the stability and infrared (IR) vibrational spectra of neutral and singly ionised fullerene cages containing between 44 and 70 carbon atoms.

VARIABLES DE PROCESO EN LA FABRICACIÓN DE FULLERENOS. SEGUIMIENTO DEL RENDIMIENTO Y DE LA PROPORCIÓN DE C60/C70 POR ESPECTROSCOPÍA ULTRAVIOLETA

open access: yesAnales (Asociación Física Argentina), 2013
Uno de los métodos de fabricación de fullerenos es la descomposición de electrodos de grafito con un arco eléctrico en una atmósfera de gas inerte. Como resultado de esta descomposición se obtiene hollín del cual se extraen entre 1% y 14% de una mezcla ...

Charge transfer excitons in optical absorption spectra of C60-dimers and polymers

open access: yes, 1996
Charge-transfer (CT) exciton effects are investigated for the optical absorption spectra of crosslinked C60 systems by using the intermediate exciton theory. We consider the C60-dimers, and the two (and three) molecule systems of the C60-polymers. We use

Diffuse interstellar bands in fullerene planetary nebulae: the fullerenes - diffuse interstellar bands connection

open access: yes, 2013
We present high-resolution (R~15000) VLT/UVES optical spectra of two planetary nebulae (PNe; Tc 1 and M 1-20) where C60 (and C70) fullerenes have already been found.

Decoherence in a Talbot Lau interferometer: the influence of molecular scattering

open access: yes, 2003
We study the interference of C70 fullerenes in a Talbot-Lau interferometer with a large separation between the diffraction gratings. This permits the observation of recurrences of the interference contrast both as a function of the de Broglie wavelength ...

Collisional decoherence observed in matter wave interferometry

open access: yes, 2003
We study the loss of spatial coherence in the extended wave function of fullerenes due to collisions with background gases. From the gradual suppression of quantum interference with increasing gas pressure we are able to support quantitatively both the ...

Lattice Heat Capacity of Mesoscopic Nanostructures

open access: yes, 2010
We present a rigorous full quantum mechanical model for the lattice heat capacity of mesoscopic nanostructures in various dimensions. Model can be applied to arbitrary nanostructures with known vibrational spectrum in zero, one, two, or three dimensions.

Low temperature fullerene encapsulation in single wall carbon nanotubes: synthesis of N@C$_{60}$@SWCNT

open access: yes, 2003
High filling of single wall carbon nanotubes (SWCNT) with C$_{60}$ and C$_{70}$ fullerenes in solvent is reported at temperatures as low as 69 $^{o}$C. A 2 hour long refluxing in n-hexane of the mixture of the fullerene and SWCNT results in a high yield ...
