  • Photoinduced cholesteric helix inversion in some systems containing chiral α,β-unsaturated ketones 
    Krivoshey, A.I.; Shkolnikova, N.I.; Chepeleva, L.V.; Kutulya, L.A.; Pivnenko, N.S. (Functional Materials, 2004)
    Cholesteric helix inversion induced with UV irradiation has been revealed in the liquid crystal (LC) system based on nematic 4-pentyl-4 '-cyanobiphenyl (5CB) which contains left-handed helix inducing chiral dopant of 3( ...
  • Use of chemical markers in antartic ecosystem studies of Demaria mount 
    Chepeleva, L.V.; Sizova, Z.A.; Yukhno, G.D.; Utevsky, S.Y.; Gamulya, Y.G.; Utevsky, A.Y.; Roshal, A.D. (Український антарктичний журнал, 2014)
    Research is devoted to using chemical markers for studying and description of ecosystems. Photosynthetic pigments – carotenoids and chlorophylls, and soil polymers – humic, fulvic acids and their salts, were used as chemical ...
