Probing the surface of synthetic opals with the vanadyl-containing crude oil by using EPR and ENDOR techniques
Marat Gafurov, Andrey Galukhin, Yuri Osin +4
Porous silica materials offer wide range of possibilities for enhancement of the productivity of oil reservoirs. However the mechanism of adsorption of polar components of crude oi…
ENDOR study of nitrogen hyperfine and quadrupole tensors in vanadyl porphyrins of heavy crude oil
I. N. Gracheva, M. R. Gafurov, G. V Mamin +4
We report the observation of pulsed electron-nuclear double resonance (ENDOR) spectrum caused by interactions of the nitrogen nuclei 14N with the unpaired electron of the paramagne…
In-situ identification of various structural features of vanadyl porphyrins in crude oil by high-field (3.4 T) ENDOR spectroscopy combined with DFT calculations
Timur Biktagirov, Marat Gafurov, Georgy Mamin +3
Structural characterization of metalloporphyrins in complex systems such as native hydrocarbons is in the focus of scientific and industrial interests since many years. We describe…
