The award-winning fields were physics and chemistry, geography, mathematics and computer science, as well as teaching and popularization of natural sciences, including mathematics and computer science.
The Dean’s Award of the Faculty of Science, UJEP is awarded by the dean of the faculty to students or recent graduates of the faculty as a bonus scholarship for outstanding results achieved in their bachelor’s or master’s theses in terms of originality, scientific value, or educational and popularization approaches and activities.
The Dean’s Awards 2025 were presented on December 17, 2025, at a gathering of the academic community.
The award-winning students in 2025 are:
Bc. Tomáš Hladík for outstanding results achieved in the field of physics and chemistry
Mobilization of bulk material using vibrations (bachelor’s thesis)
The thesis focuses on the influence of vibrations on the dynamics and kinematics of granular material. The aim was to determine the conditions under which landslide mobilization occurs. To this end, particle simulations were used, in which granular particles in a gravitational field are acted upon by an inclined vibrating wall. It was shown that particle mobilization depends primarily on the frequency of vibration.
Bc. Hana Zemanová for outstanding results in the field of physics and chemistry
Sorption of azo dyes on aluminum oxide nanoparticles: study of adsorption isotherms (bachelor’s thesis)
The thesis deals with the use of aluminum oxide nanoparticles for the removal of toxic organic dyes from polluted water. It also contributes to the understanding of the interactions of mono- and polyanionic organic particles with metal oxide nanoparticles, which may aid in the development of suitable nanoparticle-based sorption materials.
Bc. Kateřina Neckařová for outstanding results in the field of physics and chemistry
Facilitated covalent deposition of boranoxonium on inorganic material surfaces (bachelor’s thesis)
The thesis focuses on the preparation of a new series of inorganic materials modified with an oxonium derivative of cobalt bis-dicarbolide anion, a representative of extremely stable 3D heteroborane structures with specific properties. The covalent anchoring of this molecule to the surface of selected materials was mediated by the use of an organosilane coupling agent. The success of the deposition was verified using analytical instrumental techniques. The new materials were subsequently tested as heterogeneous catalysts for the esterification of fatty acids. The thesis provides important insights for further directions in the functionalization of inorganic surfaces with heteroborane.
Ing. Klára Votrubcová for outstanding results in the field of physics and chemistry
Homogeneously catalyzed esterification of fatty acids with halogen derivatives of cobalt bis-dicarbollide anion (diploma thesis)
The thesis deals with the optimization of a homogeneous fatty acid catalysis system in bio-renewable ethanol using a series of hydroxo-oxonium heteroborane acid catalysts of cobalt bis-dicarbollide anion, whose skeleton was selectively halogenated. In the experimental part, the acidity of individual representatives of this series was determined in order to identify the most effective catalyst that can be easily separated from the products after esterification, recycled, and reused. The catalytic tests were supplemented by a control experiment with sulfuric acid, whose effectiveness served as a reference for interpreting the results of halogen-heteroboronic acids. The data obtained made it possible to assess the influence of halogen on the catalytic efficiency and practical applicability of these compounds.
Matěj Krob for outstanding results in the field of geography
3D reconstruction and visualization of the extinct city district of Ostrov in Ústí nad Labem (bachelor’s thesis)
The thesis deals with the 3D reconstruction and visualization of the extinct city district of Ostrov in Ústí nad Labem. The aim of the thesis was to establish a methodological procedure for 3D reconstruction, analyze the possibilities of using individual types of data, describe the available options for graphic outputs, and create the extinct district of Ostrov as a 3D model. The thesis is based on several case studies, and the model itself was created using a combination of information obtained from cadastral maps, construction plans, period photographs, and elevation data. Overall, it can serve as inspiration for other similar projects and contributes to the preservation of the city’s cultural heritage by making the appearance of the extinct Ostrov accessible.
Mgr. Lucie Kabelová for outstanding results in the field of geography
Spatial optimization of the Emergency Medical Service system in the Ústí nad Labem Region (diploma thesis)
The work was created in collaboration with the Emergency Medical Service of the Ústí nad Labem Region and the Regional Authority. The aim was to design and compare various options for the location of emergency bases in the Ústí Region according to the selected methodology for creating a coverage plan. Network analysis and a transport model were used for the design. In shorter time periods, scenarios based on the current situation show better coverage. In terms of improving the current coverage within 20 minutes, the addition of an emergency response base in Štětí appears to be the most beneficial.
Bc. Alex Schönfelder for outstanding results in mathematics and computer science
Statistical analysis of the relationship between air quality and the traffic situation in Bílina (bachelor’s thesis)
The thesis deals with the analysis of the relationship between transport and air quality in the town of Bílina. The aim was to use time series to determine how individual transport and meteorological factors contribute to changes in pollutant concentrations. Data from the Ústí nad Labem Region Data Center was used for this purpose, which was processed, statistically analyzed, and visualized. The thesis identified and described the main factors that, according to the available data, affect air quality in the city.
Ing. Lukáš Chrastina, DiS. for outstanding results in the field of mathematics and computer science
Data management in the business sphere (diploma thesis)
The thesis deals with the issue of data management and quality in a business environment, combining a theoretical framework with practical application in a model company. The main objective of the thesis is to develop and subsequently apply a set of general rules for effective data management. The solution includes a proposal for a hybrid data quality management framework that includes data profiling, automatic validation, data cleansing, and the concept of a Data Quality Firewall. The thesis also includes a proposal for monitoring and visualizing data quality metrics as part of a comprehensive data management ecosystem. The resulting recommendations are formulated with regard to the needs of small and medium-sized organizations with a similar level of data maturity.
Štěpán Bruk for outstanding results in the field of teaching and popularization of natural sciences, including mathematics and computer science
Mathematical tasks in the real environment of a university campus (bachelor’s thesis)
The thesis presents a set of original mathematical walks professionally processed in the MathCityMap application. Didactically thought-out tasks effectively connect theory with the real world and demonstrably develop key competencies in students. This material, fully compatible with the Framework Educational Program and verified in practice, guarantees usability in teaching. The result is a comprehensive tool that offers an attractive and functional alternative to traditional education.
