Research team: Ing. Petr Bělina, Ph.D., Ing. Žaneta Dohnalová, Ph.D., Ing. Nataliia Gorodylova, Ph.D., Ing. Jana Luxová, Ph.D., Lenka Tilgnerová, Ing. Aneta Burkovičová, Ing. Blanka Hablovičová, Ing. Kateřina Těšitelová.
The presented project deals with preparation and characterisation of coloured mixed metal oxides. New functional inorganic powder materials based on complex oxides of pyrochlore and perovskite structures, phosphates of NASICON and tungstates of wolframite structures containing environmentally friendly elements will be obtained using ecological synthesis approaches. The new formulations will be characterised with regards to their phase composition and optical properties with particular attention to origin and physicochemical mechanism of their colouration. Additionally the powders will be characterised by analysis of granulometric composition, morphological properties, chemical, thermal and light stability. The main target of the project is to discover new non-toxic materials with interesting properties (colour, thermal stability, semi-conducting, anticorrosive, UV resistant, etc.) as well as broadening and systematisation of theoretical knowledge on the background of colour appearance in inorganic solids of different types and its interrelations with their structure and composition.
Viscosity and kinetic phenomena in glass-forming systems
Project GA CR 16-10562S (2016-2018):
Guarantor: prof. Ing. Jiří Málek, DrSc. (Department of Physical Chemistry)
Member of the research team: Ing. Petr Košťál, Ph.D.
Thermo-physical behavior of glass-forming liquids, i.e. the crystallization and vitrification processes, are to a large extent determined by shear viscosity. Previous studies have demonstrated that isothermal crystal growth rate corrected for thermodynamic driving force exhibits weaker temperature dependence than viscosity (this decoupling was observed mainly for oxides and small organic molecules). One of the main project aims is to extend this research to chalcogenide glass-formers and, based on the combined microscopic and advanced calorimetric studies of the nucleation processes, contribute to the overall explanation of this phenomenon. The second important project goal is to study the vitrification and structural relaxation processes and to correlate the obtained results with the viscosity behavior of the given materials. The insight gained from this research will lead to improved control of glass formation and microstructure development during controlled vitrification and crystallization. This is important for further development of new glassy and glass-crystalline materials. The aim of the project is a detailed study of viscosity dependence of crystallization, vitrification and structural relaxation in chalcogenide systems as a function of thermal history. The insight gained from this research is important for development of new glassy and glass-ceramic materials.
Progressive technology of propellants
Project TA ČR TA3-0697 (2013 – 2015)
Co-guarantor: doc. Ing. Ladislav Svoboda, CSc.
Project participants are EXPLOSIA, a.s. Pardubice (aid recipient) and the University of Pardubice (the other participant).
The project aims to develop new adaptations and forms of compounds performing the function of flame damper in the composition of simple smokeless powders. By increasing their hydrophobic properties the production cycle will be shortened via elimination of risky and cost consuming operation of vacuum drying and thus environmental burden will be subsequently minimized, which still accompanies incorporation of flame dampers into smokeless powders . New properties of used compounds will also enable increased utilization parameters of smokeless powders used in many modern weapon systems of small, medium and large calibre and thus expand possibilities of their usage not only in new powerful systems, but also in the area of automotive safety systems.

Reversible crystallization and structural relaxation in amorphous materials used for phase change recording
Project GA ČR 106/11/1152 (2011-2015)
Guarantor: prof. Ing. Jiří Málek, DrSc. (Department of Physical Chemistry)
Member of research team: Ing. Petr Košťál, Ph.D.
The project is focused on a detailed study of reversible crystallization processes as well as the structural relaxation in phase change materials that are used for rewriteable optical or RAM data storage media. Selected compositions of chalcogenide amorphous materials in Ge-Sb-Te and Ge-Sb-Se systems will be prepared. Crystallization processes will be studied by using thermal analysis and various microscopy techniques in combination with some novel methods. A systematic study of thermodynamic properties and viscosity behavior of these compositions will be performed as an integral part of this project. The experimental and theoretical study of structural relaxation in phase change materials is proposed. It will be monitored by volume, enthalpy or entropy change as a function of long term annealing at selected temperatures in the glass transition range. Such a combined approach is useful for searching new materials with tailored properties as well as to better control the reversible crystallization process and to predict the long term stability of amorphous phase. Both aspects are essential for further development of phase change memory devices.
