Behavior of C70 Fullerene in a Binary Mixture of Xylene and Tetrahydrofuran

open access: yes, 2023
The self-organization properties of C70 fullerene molecules in a xylene/tetrahydrofuran binary mixture were studied for the first time by optical absorption, refractometry, and dynamic light scattering.

Photophysical properties of the fullerenes, C60 and C70

open access: yes, 1992
Photophysical properties of the singlet and triplet states of the fullerenes, C60 and C70, have been investigated in toluene, benzene, hexane and ethanol solutions by pico- and nano-second laser flash photolysis techniques.

Isomers of C70 Dimer

open access: yes, 2001
Calculated binding energies and spectroscopic properties of C70 dimers are presented. The two most stable isomers of the set of conceivable [2 + 2] cycloaddition products are isoenergetic, and both are compatible with NMR, infrared, and Raman data on the

Raman Spectroscopic Study of As-Deposited and Exfoliated Defected Graphene Grown on (001) Si Substrates by CVD

open access: yesJournal of Spectroscopy, 2017
We present here results on a Raman spectroscopic study of the deposited defected graphene on Si substrates by chemical vapor deposition (thermal decomposition of acetone). The graphene films are not deposited on the (001) Si substrate directly but on two

Nonlinear Optical Response Of C60 And C70

open access: yes, 1992
Second-order hyperpolarizibilities γ of the buckminsterfullerenes C70 at three different wavelengths were determined by third-harmonic generation in a toluene solution and compared with those of C60.

Theoretical Study of the Raman Spectra of C70 Fullerene Carbon Peapods

open access: yes, 2015
International audienceThis work focuses on the hybrid system between C70 and a carbon nanotube (C70 peapod) where the encapsulated C70 peas and the nanotube pod are bonded through van der Waals interactions.

Fullerene C70 derivatives dampen anaphylaxis and allergic asthma pathogenesis in mice

open access: yes, 2012
Fullerenes are carbon nanospheres that can be solublized by the addition of polar chemical groups to the carbon cage, forming fullerene derivatives. One specifically derivatized fullerene compound, termed C70-Tetragylocolate (C70-TGA), has been shown to

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 ...

C70 Dimers – Energetics and Topology

open access: yes, 2004
All sp2 peanut-shaped dimeric fullerenes derived from D5h C70 are modeled. Construction of the isomers was monitored by a cyclic permutation of bonds in the linking zone of the two caps resulting from deleting the boundary of a face from the parent C70 ...
