INTERNATIONAL SCIENTIFIC CONFERENCE CONTEMPORARY MATERIALS is organized, traditionally, for the six 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. 6th international conference „Contemporary Materials“ will take place from July 04 to 06,  2013. As of this year, the work in the conference will take place within three symposia, with the opening lectures and poster presentations.SYMPOSIUM A: Science of matter, condensed matter and physics of solid states -      classical, quantum and nano- approaches to the solid state of matter -      metals and alloys -      ceramics, composite materials and polymers -      optical materials -      magnetic materials -      inorganic nanomaterials -      methods and instruments for fluid characterization -      colloid materials -      eco-materials and eco-technology   SYMPOSIUM B: Biomaterials and nanomedicine -      biopolymers -      synthetic polymers -      metal biomaterials -      ceramic and glass biomaterials -      composite biomaterials -      nanomaterials and nanotechnology in dentistry and pharmacy -      bionanoparticles, quantum dots in diagnostics and therapy -      bio-nanosensors and nanomedicine SYMPOSIUM C: Water -      structure of water -      biological waters and liquid crystals -      aquaporins, extracellular and intracellular waters -      water metabolism and disease-causing agents -      exclusion of the zone in the water -      water spectroscopy and aquaphotomics -      water of nano-layers and nano-liquids -      nanomedicine on water basis
