Life cycle assessment methods for BEV and PHEV batteries
Dvořák, Matouš ; Pokorný, Jan (referee) ; Fišer, Jan (advisor)
Electromobility is a current topic and a way to reduce the carbon footprint not only in personal transport. The operation of an electric car does not have a direct impact on emissions compared to an internal combustion engine car. However, the issue remains the production of the battery, which contains rare metals that are very energy and environmentally demanding to extract. The aim of this thesis is to analyse the energy consumption and emission footprint of the production of different types of batteries. The thesis includes a general introduction to the Life Cycle Assessment (LCA) method, followed by a chapter on battery design and the classification of batteries according to electrode chemistry. The analysis of LCA studies of batteries shows that the least energy intensive battery in terms of production is the battery with NMC cathode and in terms of emissions it is the battery with LMO cathode. However, the results are strongly influenced by the input data, which are often different in LCA studies, so it is not possible to draw a clear conclusion. Part of the thesis deals with the analysis of the environmental impacts of battery production using different energy mixes and different types of production technologies. The work can serve as a basis for a more detailed investigation of the production part of the battery and for minimizing the environmental impact of this process.

Utilizing of Electron Microscopy for Nanoparticle Detection in Selected Food
Boriková, Natália ; Hrabalová, Vendula (referee) ; Dzurická, Lucia (advisor)
This bachelor thesis deals with the detection of nanoparticles in selected food products using electron microscopy. Specifically, silver pearls, silver powder and food grade whiteness were selected for this purpose. Nanoparticles themselves can have a negative effect on the human body in high concentrations. They need to meet certain legislative standards. The main focus of this bachelor thesis is how nanoparticles could be detected in food. The theoretical part provides an insight into the properties of nanoparticles, their applications and describes methods for their determination, primarily with an emphasis on electron microscopy. In the practical part, solvents with artificially added nanoparticles were prepared and served as standards. Two samples were prepared from selected foods – with and without the addition of nanoparticles. They were analysed using low-energy electron microscope of LVEM 25E type along with elemental analysis using energy dispersive spectroscopy (EDS). The results provide the compositions of the foodstuffs in question and information on the presence of nanoparticles on their own. This research contributes to a better understanding of their characteristics and safety.

Mechanical response during dynamic loading of layers prepared by cold spray technology
Šprincl, Jan ; Válka, Libor (referee) ; Řehořek, Lukáš (advisor)
Cold spray is a relatively modern technology that falls into the additive category. It is a coating method that doesn´t cause the input material to melt. This brings many advantages, including the minimization of changes to the original structure, the absence of a heat-affected zone, and the possibility of combining different types of materials. This work mainly focuses on the deposition of Ti6Al4V titanium powder, along with other materials to supplement or modify the spray, improve its efficiency, and enhance its mechanical properties. Ballistic tests, three-point bending tests, indentation methods, optical analysis using light and electron microscopy, X-ray diffraction, differential scanning calorimetry, and the influence of thermal treatment on the structure were used to evaluate the properties. Thermal treatment led to the formation of completely new phases in the structure, resulting in a significant increase in the coating's hardness along with a reduction in its porosity. Highly hard phases based on TiC and Ti5Si3 were formed in a tough matrix composed of varying ratios of Ni-Ti and associated elements – V, Al, Si. Finally, proposals for potential future development of this material are described. Preconditions for specific improvements in the methods and procedures used in this work are laid out, with a very promising outlook for the future of this material and its potential implementation in real ballistic protection, typically in the military industry.

Apartment building
Hlásenský, Marek ; Leischnerová, Jana (referee) ; Brukner, Bohuslav (advisor)
The bachelor thesis deals with the project documentation for the construction of a residential building in Brno in the Brno – Žabovřesky district. The building is detached in a slightly sloping terrain in Podveská street. The residential building has four floors and a partially buried basement. In the basement are designed garage parking spaces, cellar cubicles and technical background of the building. There are a total of 11 residential units on the above-ground floors, 3 residential units on each floor (2×1kk and 3kk) except for the last floor, where there are only 2 residential units (1kk and 4kk). The house is designed as wheelchair accessible. The construction system of the apartment building is wall-based: the basement is made of a combination of monolithic walls and columns, and the brick floor is made of ceramic blocks. The horizontal structures consist of reinforced concrete monolithic slabs with one-way or two-way reinforcement. The perimeter walls are insulated with the ETICS contact insulation system. The foundation of the building is made on foundation strips and the roofing consists of a green flat roof.

Center for seniors in Brno-Medlánky
Minarčíková, Barbora ; Klimecký, Martin (referee) ; Gerö, Jiří (advisor)
The task of the diploma thesis is to design a senior living facility in Brno – Medlánky. This task was preceded by a pre-diploma project within the subject NGA056 – Specialized project, developed in the previous semester, which consisted of preparing an urban study with a proposal for urban structure including transportation solutions and the placement of various functions - residential areas, commercial areas, public buildings, civic amenities, a sports hall, a church, and further development of the senior living facility. The architectural study focuses on creating a suitable environment for long-term stay for seniors, meaning comfortable living, outdoor relaxation areas, adequate technical infrastructure, and a variety of services. The design stems from the concept of a compact, clear, and barrier-free base space with social areas and facilities connecting three pavilions of housing units. This ensures privacy in the housing units while providing ample space for social interaction. Access to the terrain linked with a park located on the southern side of the plot is easy from both the base floor and the housing units, providing direct contact with greenery in outdoor spaces. The main entrance leading to the base on the first floor is designed with a representative atrium, reflecting the grandeur of the entire complex. Technical and operational facilities are expanded to cover the capacity of a potential additional fourth pavilion. The entire complex reflects the requirement for peaceful and high-standard living in old age, respecting contemporary architecture and the needs of today's population. As a result, it becomes a place for contented aging.

Modelling of shear strength of concrete beams
Večeře, Jakub ; Lehký, David (referee) ; Novák, Drahomír (advisor)
The bachelor thesis deals with the modeling of reinforced concrete beams and compares their load-deflection (L-D) curves with curves obtained in an extensive experiment at the University of Lodz under the guidance of Prof. Renata Kotynia, Dr.Hab. For comparison, data from two selected beams with identical shapes, lengths, and concrete strengths were used – one reinforced with steel and the other with a composite made of glass fiber-reinforced polymer (GFRP). Modeling is carried out using nonlinear fracture mechanics of finite elements (2D) in the ATENA software. Emphasis is particularly placed on accurately modeling the bond between concrete and reinforcement. Modeling was performed in both 2D and 3D.
