In the Journal published the results of research in analytical, organic chemistry, chemical engineering, silicates, organic food technology, biotechnology and ecology. The problems of synthesis of new compounds, kinetics, reaction mechanisms, obtaining products of biosynthesis study modes cultivation of microorganisms, methods of selection, and the problem of improving and intensifying technologies of novel macromolecular compounds silicate materials. Work on Department in the research laboratories of the National University "Lviv Polytechnic" and other higher education institutions and organizations of Ukraine. For engineers, teachers and students specializing in the fields of inorganic, organic, physical and analytical chemistry, chemical engineering, macromolecular chemistry, biotechnology, technology, building materials, processes and devices of the chemical industry and the environment. In Announcer the published results of researches are inindustries of analytical, organic chemistry, chemicaltechnology of silicates, technology of organic foods,biotechnology and ecology. The questions of synthesis ofnew substances, study of kinetics, mechanisms of reactions,receipt of foods of biosynthesis, research of the modes ofcultivation of microorganisms, methods of their selection, andalso problem of perfection and intensification of technologiesof receipt of new high molecular connections, silicatematerials are examined. Works are executed on departmentsand in the research laboratories of the National university "Lviv Polytechnic" and in other higher educationalestablishments and organizations of Ukraine.
