Key learning outcomes
Chemistry graduate DSP technology and material properties is able to formulate a scientific problem, propose a hypothesis to solve it and make experimental and theoretical attempts to confirm it. An integral part of the basic knowledge of graduate DSP is the ability to critically assess published scientific information and the ability to express oneself in writing in the English language.
Occupational profiles of graduates with examples
Graduates of Chemistry, Technology and material properties are equipped with both experimental and theoretical knowledge in the field of material structures and their properties.

Issued topics of Doctoral Study Program
- Advanced materials for organic 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 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.
- 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.
- Perovskites and hybrid structures for photonic applications
The thesis will deal with the preparation and characterization of perovskites and perovskite hybrid structures, which are prospective for use in photonics with emphasis on photovoltaics, photosensors and electroluminescence devices. Attention will be focused primarily on the characterization of the optical and electrical properties of perovskite crystals and materials prepared in the form of thin films.
- Plasma nanotechnology for synthesis of complex nanostructures
The precise synthesis of materials and devices with tailored complex structures and properties is a prerequisite for the development of the next generation of products based on nanotechnology. Nowadays, the wet chemical technologies for the generation of this type of materials lack the precision to determine their properties and the synthesized materials contain numerous imperfections at the atomic level. The use of bottom-up approaches, which use small fragments of molecules or single atoms as building blocks, is an attractive approach for the synthesis of very complex and yet well-defined material structures. Preparation of organic-inorganic nanostructures with controlled physical and chemical properties is an example of highly sophisticated materials. Plasma nanotechnology will be used for the synthesis of such hybrid nanostructures with controlled mechanical and chemical properties. The synthesis must allow a continuous change in the nature of the material from organic to inorganic.
- Possibilities of carbon dioxide reduction at the production of Portland cement
Portland cement ranks and for many years ahead it will rank on the top of building binders. The annual worldwide production makes approx. 3,5 mil. tons and still keeps rising. However, the production process is burdened by huge emissions of carbon dioxide, being considered one of main greenhouse gasses. When balancing, one ton of Portland clinker equals to one ton of produced carbon dioxide. Hence this dissertation thesis will deal with the possibilities of carbon dioxide reduction corresponding to the volume of produced cements defined in the ČSN EN 197-1 standard. The work will mainly aim at pozzolana cements. Various industrial pozzolans, natural pozzolans and calcined clays will be tested. The goal will be to investigate the utilization of pozzolans in the production of cements. The reduction of clinker content in class II or IV cements to the minimum defined by the standard will contribute to the reduction of total carbon dioxide from cement industry.
- Preparation and properties of SiO2 based insulating materials
New eco-friendly insulating materials are in increased demand. We can suppose that in future a part of applied, mostly polymer based insulating materials, will be substituted. The undesired properties of recently used polymer based insulating materials are the impossibility of proper recycling and almost zero fire resistance, on the other hand they have very good insulating and physical properties. This dissertation thesis will deal with the preparation and properties of inorganic insulating materials, which should have the physical properties, mainly the bulk density and thermal conductivity, close to those of polymer insulations. The main goal is to investigate the possibilities of preparation of inorganic insulating materials based on SiO2 systems. The advantage of such materials is especially high fire resistance, easy recycling and long life-cycle.
- Probe measurements of thin films
Surface properties of thin films prepared in non-isothermal plasma will be analyzed by scanning probe microscopy using contact and semicontact modes. The surface topography of films will be correlated with the deposition conditions and evaluated according to theoretical models (KPZ, Monte Carlo, etc.) depending on the film thickness. The initial phase of film growth using the phase contrast and lateral force modes will also be studied. The selected mechanical properties of the films will be characterized by nanoindentation techniques and evaluated using the Oliver/Pharr and Field/Swain methods. Film adhesion on various substrates will be characterized by scratch test, the results of which will be used for modeling, or modification of current models, for the evaluation of adhesion work.
- Study on hydration processes in alkali-activated systems
Alkali-activated materials and binders are one of the alternatives that could lead to the decrease of carbon dioxide emission being formed at the production of Portland cement. This dissertation thesis will deal with the study on hydration processes in model alkali-activated systems. The systems based on sodium, potassium, lithium and mixed alkali activators will be investigated. Also, appropriate method for the investigation of hydration processes in alkali-activated systems will be created.
