Journal ArticleDOI
Stepwise computational synthesis of fullerene C60 derivatives. Fluorinated fullerenes C60F2k
TL;DR: In this paper, the UBS HF approach was used to study the reaction of fullerene C60 with atomic fluorine in semi-empirical codes based on the AMI technique.
Journal ArticleDOI
Viberational spectroscopy of dispersed silica: inelastic neutron scattering

TL;DR: In this article, the amplitude weighted density of states (AWDS) spectra are obtained from the INS spectra recorded at 10, 80 and 290 K. The AWDS spectra for the aerosils and the silica gels are quite different indicating a big difference in the structure of cores and shells of both the silicas as well as in the water molecule arranging on them.
Journal ArticleDOI
Computationally Supported Neutron Scattering Study of Parent and Chemically Reduced Graphene Oxide
Ireneusz Natkaniec,Ireneusz Natkaniec,Elena F. Sheka,Kacper Drużbicki,Kacper Drużbicki,K. Hołderna-Natkaniec,Sergey P. Gubin,Elena Yu. Buslaeva,Sergey V. Tkachev +8 more
TL;DR: In this paper, the inelastic incoherent neutron scattering spectra were analyzed in the frame of the computationally supported one-phonon amplitude-weighted density of vibrational states G(ω) approximation.
Journal ArticleDOI
Computationally Supported Neutron Scattering Study of Natural and Synthetic Amorphous Carbons
Elena F. Sheka,K. Hołderna-Natkaniec,Ireneusz Natkaniec,Jan Krawczyk,Yevgeny A. Golubev,N. N. Rozhkova,Vadim V. Kim,Nadezhda A. Popova,V. A. Popova +8 more
TL;DR: In this paper, inelastic neutron scattering (INS) was used to determine the structure and hydrogen content of basic structure units (BSUs) of sp2 amorphous carbons at the atomic level.
Journal ArticleDOI
High‐spin silicon fullerene Si60 and its oligomers
TL;DR: In this article, the high-spin states of the Si60 fullerene and its oligomers are considered semi-empirically by using sequential and parallel implementations of the AM1 codes.
