Physico-Chemical Studies of the Interaction Mechanism of Double and Trivalent Iron Double Oxide Nano-Particles with Serpin Protein Ovalbumin and Water

The novelty of the work is the theoretical justification and experimental confirmation of the mechanism of interaction of Fe3O4 nanoparticles with Н2О and ovalbumin-OVA, which was carried out with the help of a complex of physical and chemical studies. It was determined that the mechanism is based on the clustero-philicity of nanoparticles and hydrogen, electrostatic and van der Waals interactions.

A mechanism of Portland cement hardening in the presence of finely grained glass powder

The glass wastes as a cullet are widely used for the production of building materials mainly as inert aggregate. However finely grained glass powder has the very developed surface, so can not be passive toward cement solutions, what was confirmed in practice. In literature data there is no information about chemical influence of finely grained glass on the process of hardening, especially in an early pre-induction hydration period, which substantially causes the structure formation of cement stone and its properties.
