D. Avramov at DCPBUT

Dunja Avramov (M.Sc. student) from the Faculty of Technology, University of Novi Sad, Serbia (FTUNS) visited Department of Ceramics and Polymers, Brno University of Technology, Czech Republic (DCPBUT) for one month training stay (from 13th September to 11th October 2009) within the Mobility and training activity (WP 1).

Dunja Avramov had an opportunity to be educated and trained under supervision of Prof. Dr. Karel Maca. The main goal of her training and education was related to preparation and characterization of high density alumina, using different procedures for powder preparation and methods of powder sintering. She was trained in preparation of samples, green bodies for sintering using Cold Isostatic Pressing (Autoclave Engineering, Inc., USA), and in their subsequent sintering using different procedures (single, two and three step procedures) in high temperature dilatometer (L70/1700, Linseis, Germany) and high temperature furnace (K1700/1, Heraeus, Germany). She was also trained in sample preparation using devices for cutting and polishing of samples (cutter Accutom-50, Struers, Germany and polisher TegraPol-25, Struers, Germany, respectively). Along with that, she was trained to apply various methods of characterization and interpretation of obtained results, such are: determination of surface area and pore volume using BET method (ChemBet 3000, Quantachrome, USA) and mercury porosimetry (Pascal 440, Porotec, Germany) and scanning electron microscopy (Philips XL30). In addition, Dunja Avramov spent some time working with the modified Archimedes' method for measuring the density of samples. Average grain size of sintered samples was estimated from SEM micrographs using Linear Intercept Method (standard EN 623-3).



O. Bera at DCPBUT

Oskar Bera (Ph.D. student) from the Faculty of Technology, University of Novi Sad, Serbia (FTUNS) visited Department of Ceramics and Polymers, Brno University of Technology, Czech Republic (DCPBUT) for one month training (from 13th September to 11th October 2009) within the Mobility and training activity (WP 1). This was his second training at DCPBUT, but this time costs were covered from other project. Due to very good results and nice experiences after the first two months training in spring 2009 cooperation with Dr. Trunac has extended. During the second study visit O. Bera was additionally trained for preparation of polystyrene-fullerene and polystyrene-carbon black polymer nanocomposites and characterization of prepared materials. This activity is good indicator of the level of collaboration and success of the RP-DEMATEN project in developing closer cooperation among their members.


A. Duszová at IMCASCR

Annamária Duszová (Ph.D. student) from the Institute of Materials Research of Slovak Academy of Science, Košice, Slovakia (IMRSAS) visited the Institute of Macromolecular Chemistry, Academy of Sciences, v.v.i., Prague, Czech Republic (IMCASCR), for one-month training and education (from 15th February to 13th March 2010) within the Mobility and training activity (WP 1).

The main goal of the visit was training for preparation of different polymer and polymer + CNF (carbon nanofiber) nanocomposites. During her stay at the Institute, she worked at the Department of Polymer Networks and Mechanical Properties, supervised by Dr. Milena Špírková. During her one-month training and education stay at the Institute she has learned how to prepare different polymer based materials, especially polymer + CNF nanocomposites with different volume fraction of CNFs. The main compounds were:

  • Carbon nanofiber – MF-C150
  • macrodiol polybutadiene diol; end-capped by primary OH groups (LBH-P (MW=2000g/mol; “D2000”))
  • 1,4-butandiol – chain extender
  • HMDI - 1,6-hexamethylene diisocyanate
  • MTBE - methyl-terc.butyl ether (solvent) dissolvent
  • DBTDL , dibutylcindilaurate (catalyst) dissolved in oil Marcol (macrodiol compatibility).


During the stay Annamária Duszová learned a lot about different processing and characterization methods for investigation in polymer research. She was also trained how to characterize the processed materials by different techniques (spectroscopy techniques, atomic force microscope, etc.). During the stay she used the Institute library to improve her knowledge in the field of polymeric and organic synthesis. She also enjoined the possibility for access to scientific papers via the Institute web server, for study of achievement in the nanocomposite field. In addition, the processed samples will be characterized and tested also at the IMRSAS in Kosice and comparative analysis will help her to better understand the relationship between processing, structure and properties.


V. Pouchly at FTUNS

Vaclav Pouchly (Ph.D. student) from Department of Ceramics and Polymers, Brno University of Technology, Czech Republic (DCPBUT) visited Faculty of Technology, University of Novi Sad, Serbia (FTUNS) for one month training stay (from 20th February to 19th March 2010) within the Mobility and training activity (WP 1).

Prof. Vladimir Srdić, supervisor of his stay at FTUNS, showed him all laboratories at University of Novi Sad for synthesis, processing and characterization of materials. During the stay Vaclav Pouchly had practical training at Zetasizer Nano ZS (by Mr. Milan Nikolic - experienced researcher from FTUNS) and learned a lot about problems in exact evaluation of obtained results of particle size distribution. He was trained for syntheses of core-shell particles based on SiO2 core and ferrite and perovskte shell by Mr. Milan Nikolć and Bojana Mojić. In addition, he shared his experience in shaping of nanopowders by pressing and sintering of pressed pellets with other young scientists from FTUNS. He also promised that the sintering in dilatometer and characterization of these pellets will be done in DCPBUT and explained to young scientists from FTUNS during next visit.

During his state in the Novi Sad Vaclav Pouchly also participated training course of Dr. Konstantinos Giannakopoulos from the Institute of Materials Science, National Center for Scientific Research “Demokritos” Athens, Greece (IMSNCSR) and lecture of Dr. Maca (DCPBUT) “The research of advanced ceramic processing at the Brno University of Technology and its future perspectives”. Vaclav Pouchly had the lecture „Basic principles of sintering phenomena“ for undergraduate students. He also visited several laboratories and has valuable discussions with many researchers from Novi Sad and helped them with digitalization of dilatometer THETA 1200C.



E. Bartoničkova at IMSNCSR

Eva Bartonickova (PhD student) from Department of Ceramics and Polymers, Faculty of Mechanical Engineering, Brno University of Technology (DCPBUT) visited the Institute of Materials Science, National Center for Scientific Research “Demokritos” Athens, Greece (IMSNCSR), for training within the Mobility and training activity (WP 1). However, she was at IMSNCSR only two weeks (from 6th to 20th April 2010) instead of one month, since this was the first visit organized between IMSNCSR and DCPBUT centers. Other two weeks will be done later (in the third Project year).

During the training Dr. Konstantinos P. Giannakopoulos showed her all facilities in Demokritos research center, especially the Institute of Materials Science where the research is focused mainly on structural studies and magnetic properties of materials. The X-Ray analyses of perovskite powders prepared on her Department of Ceramics and Polymers were done with assistance of Dr. Evagelia Moshopoulou. Further they discussed the problems of determination of exact structure of perovskite compounds. Dr. Evagelia Moshopolou introduced her special programs Poudrix a GSAS (General Structural Analysis System) for general fitting of structure from obtained experimental data. During her stay she had used the library and gathered many papers and literature data which helped her in understanding the structure refinement using GSAS programe. The talks about determination of magnetic and transport properties of materials (mainly superconductors based on Nb and V) by help of SQUID (superconducting quantum interference devices) equipment were given by Dr. Dimosthenis Stamopoulos.
