2. Advanced materials for organic and hybrid solar cells

   The work will deal with the preparation and characterization of materials - organic semiconductors, which are perspective for use in the field of organic and hybrid photovoltaics. Organic solar cells will be prepared and characterized by methods of material printing and other methods and their properties will be studied. Attention will be focused on characterization of optical and electrical properties of materials and solar cells. The aim is to optimize the properties of solar cells with respect to their specific application possibilities. It is expected that the PhD student will be involved in an international research project focusing on organic photovoltaics.

3. Effect of measures to reduce the carbon footprint on the properties of Portland cement

   The subject of the work will be research on the influence of individual production measures in the production of Portland cement, which are currently being rapidly introduced in connection with the fulfillment of the challenges of the European Green Deal agreement to reduce carbon dioxide emissions. Among the basic measures are the application of an increasing number of alternative fuels replacing fossil fuels, the use of alternative non-carbonate raw materials for the production of clinker and the expansion of the spectrum of supplementary cement raw materials for the production of mixed cements. At the same time, new production technologies and technological elements reducing carbon dioxide emissions are gradually being introduced. All these interventions in the established production of Portland cement must necessarily affect its composition and properties, which brings new challenges in the field of research and development of Portland cement.

4. Historical binders and the possibilities of their use in the current construction industry

   The current construction industry relies primarily on the production of Portland cement. Portland cement is a modern hydraulic binder, whose durability and stability can be assessed for a little over a hundred years. In contrast to this phenomenon of the present, there are still many preserved buildings from several thousand years before Christ, which are still standing whole or their torso. This dissertation will mainly deal with earlier technologies for the production of ancient binders and their applications in the contemporary construction industry. In particular, it will be about the study and the possibilities of using Romanesque and Roman cements. In the case of the use and application of these binders in the current construction industry, the amount of CO2 produced during the production of Portland cement could be reduced and a considerable amount of energy could be saved, since both of the above-mentioned historical binders are produced at significantly lower temperatures.

5. Influence of carbon dioxide partial pressure on the mechanism and kinetics of gas-solid carbonation

   The work is focused on the study of the influence of the partial pressure of carbon dioxide on the kinetics, reaction mechanism and thermodynamics of the formation of an activated complex in the process of dry carbonation of calcium oxide prepared by calcination of lime or dolomite. The effect of additives and processing temperature, so-called firing hardness, on this process will also be studied.

6. Kinetic stability and rheological properties of photosensitive ceramics suspensions for 3D printing

   The work is focused on the study and description of the rheology of photosensitive stabilized suspensions of ceramic powders for 3D printing. Depending on the dispersant used, the kinetic stability and rheological model describing the properties of these suspensions will be evaluated in order to optimize them so that they can be used in the preparation of technical and functional oxide ceramics.

8. New materials and printing technologies for efficient touch devices and sensors

   TThe work is pointed out towards study of novel materials and application of the material printing techniques in the field of printed electronics, mainly touch-screens and/or organic and bioelectronic applications. Screen-printing technology will be in-dept studied – design of structures of electronic devices , projection on the screen by photolithograpy, the technology of the printed pastes, screen-printing of samples. The printed films will be characterized and estimated by mechanical, optical and electrical measurements. The work is implemented with the support of applied research projects with the participation of a wider consortium of industrial and other partners.

9. Non-fullerene acceptors based on high performance dyes and pigments for organic photovoltaics

   The work deals with targeted chemical modification of organic dyes and pigments, synthesis of their polymers and co-polymers. The design of molecules will be focused on the study of the effect of chemical modification on the resulting electron-acceptor properties of materials for applications in organic photovoltaics

    The work will deal with preparation and characterization of new organic materials, which are prospective for use in bioelectronics. Attention will be focused primarily on the characterization of the optical and electrical properties of materials prepared in the form of thin films. The possibilities of using materials in thin-film sensory systems to stimulate cells and study their response will be studied. The work will be implemented with the support of a basic research project in collaboration with other workplaces, including foreign ones.

11. One-part alkali activated systems

    In alkali-activated binder research, one-part systems are becoming more and more popular, where the activator is pre-mixed in a solid state with the precursor, so that when using this binder, it is only necessary to add water, similar to ordinary Portland cement. From a practical point of view, in addition to the well-established preparation procedures, it is also advantageous that the storage of highly alkaline solutions and their handling is eliminated, but the influence of the human factor on the resulting properties of the material also decreases. Certain pitfalls, on the other hand, are the hygroscopicity of the activator, its dissolution in water, the potentially different kinetics of the formation of reaction products compared to ordinary liquid activators, but also the low efficiency during alkaline activation, since activators with a lower pH are mostly used and, if possible, in the smallest possible doses due to economic, but also ecological aspects. One-component systems also differ from two-component systems in the rheology and function of the additives. The work is therefore mainly focused on the early stages of alkaline activation of single-component systems (rheology, temperature development, reaction processes, functionality of organic additives) and the optimization of their composition also with regard to long-term properties. Part of the work will also be the study of the microstructure of these systems, the identification of emerging products, and the like.
