The Material and Solution Structure Research Group (MASOST) was founded in 2009 by Professors Dr. Pál Sipos and Dr. István Pálinkó (1959 – 2021). The main profile of MASOST is primarily the implementation of fundamental research projects relevant to heavy industry, and the sponsors are mainly industrial partners. Within this, the research work covers industrially significant homogeneous and heterogeneous equilibria in solution, especially in concentrated aqueous solutions, the transformations of solid phases from solutions and the production, testing and applications of layered double hydroxides (primarily in the field of catalysis). Their current projects include the fundamentals of the neutralization of red mud (or bauxite residue) to obtain soil from it, the transformations of various Li+-containing inorganic compounds relevant to battery manufacturing and analytical research aimed at increasing the efficiency of secondary oil recovery.
