Physicochemical Processes in Natural Waters. Important processes such as the pH and transport of pollulants to and from the sediments of aquatic,systems is regulated by precipitation and dissolution phenomena. The precipitation and dissolution processes in artificial seawater are investigated at conditions of sustained supersaturation. Protection and Restoration Methods of Historic Monuments. Marble and lime have been used for the construction of historic monuments.
Climatic factors are responsible for the deterioration of the surface of the stones.
The process is modeled after the dissolution of calcite crystals and the physicochemical factors influencing the rates of dissolution are quantitated. Preparation of TiO2 catalyst supports. Purification of Crystals by melt Crystalization. Melt crystallization is a promising method for the purification of organic compounds resulting in energy saving. The behaviour of metals including aluminum and its alloys and of steel is investigated in aqueous corrosive media by DC and AC electrochemical methods.
