Journal ArticleDOI
Continuous symmetry of C60 fullerene and its derivatives.
TL;DR: In this article, Sheka and Fullerenes showed that the I(h) symmetry of fullerene C(60) is at most 99.99% I (h).
Journal ArticleDOI
Pressure dependence of phonon energies in d8-naphthalene
U. Schmelzer,E L Bokhenkov,B. Dorner,J Kalus,Gordon A. Mackenzie,I. Natkaniec,G. S. Pawley,Elena F. Sheka +7 more
TL;DR: In this article, pressure-induced changes of the phonon dispersion curves of the external modes in d8-naphthalene (C10D8) have been determined at 100K for the ( xi 00) and (00 xi ) directions by coherent inelastic neutron scattering.
Journal ArticleDOI
Fractals of graphene quantum dots in photoluminescence of shungite
TL;DR: In this article, the photoluminescence spectra of individual GQDs were observed in frozen toluene dispersions which pave the way for a theoretical treatment of GQD photonics.
Journal ArticleDOI
Determination of phonon eigenvectors in naphthalene by fitting neutron scattering intensities
G. S. Pawley,Gordon A. Mackenzie,E L Bokhenkov,Elena F. Sheka,B. Dorner,J Kalus,U. Schmelzer,I. Natkaniec +7 more
TL;DR: In this article, the coherent neutron scattering intensities from five phonon modes in naphthalene have been measured at twenty four points in reciprocal space, and a fit to these intensities has been obtained by altering the eigenvectors iteratively.

Computational Strategy for Graphene: Insight from Odd Electrons Correlation
TL;DR: In this paper, the Hartree-Fock theory is applied for the consideration of magnetic properties of nanographenes, their chemical modification by the example of stepwise hydrogenation, as well as a possible governing the electron correlation by the carbon skeleton deformation.
