Slovak University of Technology in Bratislava

Institute of Materials Science, Faculty of Materials Science and Technology, Slovak University of Technology Bratislava

Slovak University of Technology in Bratislava (STU) is a modern educational and scientific institution with over 19.000 students every year. Established in 1937, the STU is the oldest and largest technical university in Slovakia. Being part of the Faculty of Materials Science and Technology the Institute of Materials Science has a long history and wide know-how in the development and characterization of new materials, including 2G high temperature superconductors, lead-free solders, complex metallic alloys, nickel-based alloys, high-strength materials but also non-metal materials and polymers. The Institute has established an intensive network with local and foreign research institutions as well as industrial companies. Researchers of the Institute implement international projects supported by European commission, projects supported by ERDF and national projects supported by APVV and VEGA agencies.

The Institute of Materials Science disposes of an analytical infrastructure, which is unique in Slovakia. For the preparation, investigation and characterization of composited superconducting tapes concerning the microstructure, crystal orientation, chemical composition, morphology, mechanical and thermo-physical properties they dispose – amongst other - over: a scanning electron microscope (including EDX, WDX and EBSD analytics), an x-ray diffractometer, a high-resolution transmission electron microscope, a confocal laser scanning microscope, an Ar-ion polisher for preparation of cross-section samples, a universal machine for mechanical testing of superconducting tapes, a device for conventional and induction soldering, a power compensation differential calorimeter, a dilatometer, and a laser flash apparatus.
