Morozova L. Cluster structures of water on the interfacial boundaries of silica and some tissues of the body. The effect of strong acids and organic environment

Thesis deals with the adsorption and interfacial properties of samples of model systems based on highly dispersed silica with mineral acids and biological tissues in organic solvents medium. Hydrate layer properties of the objects have been studied by 1H NMR methods, infrared spectroscopy, thermogravimetry. Significant differences of thermodynamic characteristics of hydratation process by varying the properties of the surface texture nanosilica have been revealed. The possibility of clustering in organic solvents medium and low degree of dissociation of strong mineral acids in water interfaces have been showen. Peculiarities of "Silix" behavior in experiment with the tissues of the gastrointestinal tract of rats have been studied. It has been proved that water, present in the internal cavities of the stomach and intestine tissues of living organisms, is represented by clusters of weakly associated state. Experiments with pancreatin digestive enzymes revealed the existence of clusters of different sizes and dissolution phenomenon weakly polar components in the water by forming a specific local organic environment.
