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. They control a number of methods for the characterization of materials not only at the level of theoretical description , but are also familiar with the practices of their use in practice ( a lot of information gain among others, during internships at foreign universities ) . Stays allow them to also expand your language skills. Theoretical foundations of obtain in appropriately selected subjects. Graduates also have experience in the provision of information and presentation of results at conferences and professional seminars , not only in Czech , but also the English language. Doctoral students are also encouraged to independent and creative thinking and technological foresight , allowing them to solve technological problems in a number of operations. Given that the study course " Chemistry, Technology and Properties of Materials " is a modern -conceived field of doctoral study, which is based on the current state and needs of the chemical, electronic and consumer goods industries , graduates are eligible to work in both the industrial sector and areas applied and basic research. It should be noted that the graduate study program also has a basic knowledge of chemistry and physics. The general basis is extended by special courses that include, for example, the progress of chemistry and physics , nanotechnology , use of secondary raw materials, bioengineering and the use of chemical and physical laws in the areas of inorganic and organic compounds.

Issued topics of Doctoral Study Program
- Alkali activated and hybrid binders
Design, preparation and further physical, chemical nad structure characterization of alkali activated binder and hybrid binders, i.e. in combination with Portland cement.
- Biodegradable polymers synthesized in non-isothermal plasma
Polymers prepared by chemical vapor deposition (CVD) polymerization have found broad acceptance in research and industrial applications. However, their intrinsic lack of degradability has limited wider applicability in many areas, such as biomedical devices or regenerative medicine. In 2017, for the first time, researchers from University of Michgan demonstrated a backbone-degradable polymer directly synthesized via CVD. Synthesis of biodegradable plasma polymer by plasma-enhanced chemical vapor deposition (PECVD) is a big challenge and would found broad use not only in biomedical applications.
- Boisensors and bioactuators based on organic semiconductors.
The research will focus on the development of biosensors and bioactuators for the sensing of electrogenic cell signals and the electrostimulation of living cells and tissues, for example stem cell differentiation, for pharmaceutical and medical research, in cooperation with the Institute of Biophysics of the Academy of Sciences of the Czech Republic. Emphasis will be put on the selection and testing of biocompatible materials from the group of organic semiconductors.

- Electrooptical measurements of soft and solid matter
Měření elektrických (I-V, SCLC, efekt pole, impedance, kinetika) a optické vlastnosti organických a anorganických látek. Vývoj originálních sestav pro elektrooptické měření.
- 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.
- Organic-inorganic 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.
- 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.
- 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.
- Separation of air mass pollutants
The work will focus on the technological possibilities of the air quality improving by means of selected pollutants separation. Attention is focused on the work with the currently most painful air quality parameters: -the content of ultrafine airborne particles of dust and aerosols in the air which exceeds mostly very often now -and the contents of certain gaseous contaminants as well. The experimental part of the selected segment separation work will be implemented on a pilot separator size.
- Stability of sizings of fiber reinforcements for polymer composites
Plasma surface modification of glass fibers is an alternative technology to wet chemical processes employed for commercial sizing used for glass fiber-reinforced polymer composites. The sizing (functional coating) must improve compatibility and form a strong but tough link between the fiber and the polymer matrix. However, commercial sizing is a heterogeneous coating of variable thickness, with only a small portion of the total sizing chemically bonded to the fiber surface. In addition, the bonding is hydrolytically unstable. The task is to prepare a plasma coating of glass/basalt fibers with a mechanical response of polymer composite comparable to commercial sizing for polyester and epoxy matrices and to compare the degradation rate of the surface treatments.
- Stabilization of newly emerging solid phase disintegration surfaces
Research of the additive of milling processes with surface-active chemicals which allow to suppress the reaglomeration tendencies of the newly formed particle surfaces that result from the milling processes and thus allow for greater fineness of the milling stock with lower energy demands for the milling processes.
