1. 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.

   Tutor: Weiter Martin, prof. Ing., Ph.D.

2. Design and Synthesis of organic semiconductors with increased molecular stacking and solubility

   The work deals with the synthesis and characterization of advanced organic semiconductors, their oligomers and polymers, which will be modified by an implemented fragment ensuring high self-assembly. Another important parameter will be the satisfactory solubility of the studied organic materials. The newly synthesized systems will exhibit 2D and 3D frameworks for applications in organic photonics and electronics.

   Tutor: Krajčovič Jozef, prof. Ing., Ph.D.

3. Electrical and dielectric characterization of thin organic films

   The work includes construction of modules and devices for electrical measurement of thin organic films, performance of measurements and development of models for explanation of the observed phenomena.

   Tutor: Zhivkov Ivaylo, doc. Mgr., Ph.D.

4. Non-traditional approaches to rheology of inorganic binders

   Key aspects of the application of inorganic binders include their rhelogical properties. These must be suitably adjusted to suit the respective purpose of use. Diametrically different are the requirements for ordinary concretes, self-compacting concretes, shotcrete or, for example, for 3D printing. Usually, these properties are determined from flow curves by interpolation with a suitable rheological model, but this approach has only limited possibilities. Measuments in the oscillating mode provide a far more comprehensive desciption of material behavior, but they are in the field of inorganic binders at the beginning of their development. The main goal of this topic is a detailed characterization of the reological behavior of common and alternative binders using oscillating measurements, but also to find connections between observed results with surface chemistry of investigated systems and use of knowledge to design suitable additives for alternative binders where common additives fail.

   Tutor: Ptáček Petr, prof. Ing., Ph.D.

5. Novel organic materials for applications in bioelectronics

   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.

   Tutor: Weiter Martin, prof. Ing., Ph.D.

6. Structure and properties of polymer fibers for sustainable textile applications

   Textile applications are a source of a large number of microplastics in the environment. The topic aims to contribute to the development of sustainable textiles based on biosource materials. A great advantage would be their biodegradability in wastewater, where they are in significant concentrations due to washing and drying of textiles. The work is therefore focused on the development of materials for spinning technology and the study of the influence of the chemical structure of these materials on the mechanical properties, morphology and application properties of fibers. It also includes a study of the possibilities of ecological disposal of these materials.

   Tutor: Přikryl Radek, Mgr., Ph.D.

7. Study of electric and dielectrical properties of materials of photovoltaic cells

   The work will be focused on the study of dielectric properties (complex permittivity) of materials used for the photovoltaic cells. To study methods will be used impedance spectroscopy and DC measurements

   Tutor: Zmeškal Oldřich, prof. Ing., CSc.

8. Study of optical phenomena on thin-film structure whith perovskites layers

   Work will be focused on the study of surface properties of thin films used in the preparation of thin film structures with layers of perovskites

   Tutor: Zmeškal Oldřich, prof. Ing., CSc.

9. Synthesis and applications of natural-inspired materials for photocatalytic processes

   The work deals with the synthesis and characterization of nature-inspired molecules, containing fragments that allow the distribution of charge within the organic skeleton. Molecules will also be designed for synthesis on the basis of quantum chemical (DFT) calculations in order to meet the required criteria as accurately as possible. Newly synthesized organic systems will be studied and used for photocatalytic applications.

10. Synthesis and characterization of activated belitic cements

    The work is focused on preparation of cements of high contents of beta-dicalcium silicate (belite) and on improvement of its hydraulic activity with suitable additives.

    Tutor: Ptáček Petr, prof. Ing., Ph.D.

11. Synthesis and characterization of activated belitic cements

    The work is focused on preparation of cements of high contents of beta-dicalcium silicate (belite) and on improvement of its hydraulic activity with suitable additives.

    Tutor: Ptáček Petr, prof. Ing., Ph.D.

12. Synthesis and characterization of polymeric barrier coatings from renewable sources

    The content of this topic is research and development of coatings with controlled properties from renewable sources as an alternative to petrochemical coatings. Polymer coating is used in the packaging industry, the production of water purification systems, the pharmaceutical industry, etc., in which the value of production possibilities is added and renewable resources can be used, for example, in the production of consumer disposable goods. The scope of the work is to make a search aimed at clarifying the relationship between the structure of precursors and the physicochemical properties of the resulting layers. The experimental part of the work will focus on the synthesis of mixtures for the formation of coatings, especially in terms of structural and physicochemical modification of the input reactants. The primary goal of this modification will be to ensure their controlled polymerization from the precursor and to ensure the occurrence of specific functional groups in the structure of the precursor, which will mediate the desired physical properties of the mixture after its deposition on various substrates. Detailed physico-chemical characterization of input precursors of coatings and resulting coatings will be performed, in which the main attention will be paid to transport (diffusion release rate or access of active substance coating mixture, gas permeability) properties and their structural and morphological stability under various application relevant conditions (kinetics chemical and / or biological degradation).

13. Synthesis and characterization of PTC ceramics based on BaTiO3

    The topic is focused on preparation and synthesis of semiconductive PTC (Positive Temperature Coeficient) ceramics based on dopped BaTiO3 for applications in electrotechnical and automotive industry. The work wil be realized in cooperation with the industrial partner of study program the company TDK Electronics.
