INTERNATIONAL SCIENTIFIC CONFERENCE „CONTEMPORARY MATERIALS“ is organized, traditionally, for the fifth time, by the Department of Natural and Mathematical Studies of the  Academy of Sciences and Arts of the Republic of Srpska. Conferences that were organized in previous years attracted a great deal of interest of scientific and professional public, and thus motivated and obliged us to ensure that the future conferences are even better organized. The purpose of this conference is to discuss the current topical issues, in a comprehensive and multidisciplinary manner, concerning contemporary materials and their application in science, technology and industry. This year too, the eminent scientists and scholars from country and abroad will take part in the plenary and poster sessions.
