Study plan creation
The doctoral studies of a student follow the Individual Study Plan (ISP), which is defined by the supervisor and the student at the beginning of the study period. The ISP is obligatory for the student, and specifies all duties being consistent with the Study and Examination Rules of BUT, which the student must successfully fulfill by the end of the study period. The duties are distributed throughout the whole study period, scored by credits/points and checked in defined dates. The current point evaluation of all activities of the student is summarized in the “Total point rating of doctoral student” document and is part of the ISP. At the beginning of the next study year the supervisor highlights eventual changes in ISP. By October, 15 of each study year the student submits the printed and signed ISP to Science Department of the faculty to check and archive.
Within the first four semesters the student passes the exams of compulsory, optional-specialized and/or optional-general courses to fulfill the score limit in Study area, and concurrently the student significantly deals with the study and analysis of the knowledge specific for the field defined by the dissertation thesis theme and also continuously deals with publishing these observations and own results. In the follow-up semesters the student focuses already more to the research and development that is linked to the dissertation thesis topic and to publishing the reached results and compilation of the dissertation thesis.
By the end of the second year of studies the student passes the Doctor State Exam, where the student proves the wide overview and deep knowledge in the field linked to the dissertation thesis topic. The student must apply for this exam by April, 30 in the second year of studies. Before the Doctor State Exam the student must successfully pass the exam from English language course.
In the third and fourth year of studies the student deals with the required research activities, publishes the reached results and compiles the dissertation thesis. As part of the study duties is also completing a study period at an abroad institution or participation on an international research project with results being published or presented in abroad or another form of direct participation of the student on an international cooperation activity, which must be proved by the date of submitting the dissertation thesis.
By the end of the winter term in the fourth year of study the students submit the elaborated dissertation thesis to the supervisor, who scores this elaborate. The final dissertation thesis is expected to be submitted by the student by the end of the fourth year of the studies.
In full-time study form, during the study period the student is obliged to pass a pedagogical practice, i.e. participate in the education process. The participation of the student in the pedagogical activities is part of his/her research preparations. By the pedagogical practice the student gains experience in passing the knowledge and improves the presentation skills. The pedagogical practice load (exercises, laboratories, project supervision etc.) of the student is specified by the head of the department based on the agreement with the student’s supervisor. The duty of pedagogical practice does not apply to students-payers and combined study program students. The involvement of the student in the education process within the pedagogical practice is confirmed by the supervisor in the Information System of the university.

- Dielectric relaxation spectroscopy of lignin
Popis (AN): The object of the work is to investigate the dielectric behaviour of lignin at the frequency interval 1 mHz – 1 GHz and in the temperature interval 20 K – 400 K. Lignin, an irregular polymer of three basic alcohols, makes up about 15 – 30 % of wood and is responsible for the mechanical strength and rigidity and, thus, for the growth of trees. For years, it has stood in the shadow of its more applicable counterpart, cellulose, but in the recent years, the commercial attention starts to turn to its favour. Lignin can be used for different industrial and biomedical applications, including biofuels, chemicals and polymers, and also for the development of nanomaterials for drug and gene delivery. Also, hormones supporting the increase of lignin share in wood, have been recently patented by CEITEC research team from the Masaryk University in Brno together with their Norwegian research colleagues. Equipment available: measurement equipment for the frequency range 10-3 – 109 Hz and Janis helium cryostat CCS-400/204 for the temperature range 10 – 500 K. Among the most powerful systems is Novocontrol ALPHA-AT high-resolution high-frequency analyzer with frequency range 3 μHz – 40 MHz and Nicolet 8700 FTIR-spectrometer with wave number range 20 000 – 350 cm-1.

- Reducing internal stress and improving the tribological properties of materials
This dissertation examines the properties of polymeric, composite and other materials produced by additive production, especially 3D printing. This method can affect the resulting parameters and properties, yet those inaccuracies can be fixed by further postprocessing. For surfaces, we will investigate the tribological properties of materials. The result will be for us to design several techniques that will improve mechanical, thermal and chemical resistance. Having said that, these techniques will include cold spray, plating, sputtering, etc. Moreover, we will devise methods which will be able to change the properties of materials without any further additive processes. We are speaking of methods like annealing, either in a furnace or in a water bath, casting layers or sintering. As a result, we expect to create a set of procedures, explaining how to properly and accurately improve certain material parameters.
- Use of the acoustic emission method for the evaluation of degradation processes in implants and in the formed layer of cold kinetic deposition
The aim of this work will be to clarify the possibility of using the acoustic emission method for qualitative assessment of degradation processes and limit states in implant materials with a layer of cold kinetic deposition (cold spray). Although the research will be primarily focused on new implants made of different materials, the results will be assessed by the method of comparison, both for new and current implants. During the basic research, it will be necessary to perform a number of laboratory measurements intervening in various scientific disciplines, in the solution of which it will be necessary to use an interdisciplinary approach. The obtained results and knowledge from basic research will be fully usable for applied research.

- Fluctuation phenomena of quartz crystal microbalance
Quartz crystal microbalance (QCM) belongs to a group of high sensitive sensors for detection of chemical substances dissolved in gas or liquid. This type of sensor is applied routinely by biologists and chemists to obtain information about chemical processes. The core of QCM is the AT-cut quartz crystal that oscillates at a resonant frequency which is determined by mass and geometry of the crystal as well as several other factors (temperature, applied voltage etc.). The quartz electrodes are covered by sorption layers with affinity to the molecules of the detected matter. Sorbed matter (molecules of the detected mass) represents mass increment and the change of the viscoelastic properties of the layer, which leads to the change of resonant frequency. The aims of the work are two-fold: to study theoretically and experimentally fluctuation processes in these sensors and to optimize a design of QCM sensors in order to get a maximal sensitivity.
- Operational amplifiers design techniques with extremely low voltage supply
New design techniques for operational amplifiers with extremely low voltage supply. The voltage supply target is in range of 0.5-0.3V with power consumption in range of nanowatts. The function of the proposed structures will be described and simulated by using 0.18 µm CMOS technology from TSMC. The verified design of this operational amplifier should be the main result.
