Yatluk, I. A. Grigor'ev, I. A. Kirilyuk // Russian Journal of Physical Chemistry A, Focus on Chemistry. - 2011. - Vol. 85, № 6. - P987-992. - Bibliogr. : p. 991-992 (24 ref.) Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: Hybrid organo-inorganic materials based on the chitosan-SiO2, chitosan-Al2O3, and chitosancellulose systems are prepared. The structure of the surface is studied by means of EPR spectroscopy using the stable pH-sensitive nitroxyl radical, 4-dimethylamino-2-ethyl-5,5-dimethyl-2-pyridine-4-yl-2,5-dihydro-1H-imidazole-1-oxyl as adsorbed probe molecules, and the processes that occur during the formation of hybrid materials are considered \\\\Expert2\\nbo\\Russian Journal of Physical Chemistry A, Focus on Chemistry\\2011, V.85, N 6, p.987.pdf |
