Příprava a studium heterogenních nanomateriálů kov/oxid kovu
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2024)Datum obhajoby: 18. 6. 2024In this study, heterogeneous gold/niobium oxide nanomaterials were prepared and investigated. The possibilities of preparing these materials with two different niobium oxide architectures, namely thin sputtered layers and ... -
Maximal noncompactness of operators and embeddings
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2024)Datum obhajoby: 18. 6. 2024We will focus on studying the ball measure of non-compactness α(T) for various particular instances of embedding operators in sequence spaces. Our first main goal is to find necessary and sufficient conditions for an ... -
Study of phase transitions in models with itinerant and localized particles via machine learning
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2024)Datum obhajoby: 18. 6. 2024Phase diagrams in condensed-matter physics are often very complex. The development of methods that can identify distinct phases without any prior knowledge is, therefore, of great interest. In this study, we applied ... -
Spektrum cesarovských operátorů
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2024)Datum obhajoby: 18. 6. 2024Title: Spectrum of cesàro operators Author: Matyáš Maleček Department of Mathematical Analysis: Department of Mathematical Analysis Supervisor: prof. RNDr. Jiří Spurný, Ph.D., DSc., Department of Mathematical Analysis ... -
Hausdorff and capacitary dimension
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2024)Datum obhajoby: 18. 6. 2024This bachelor thesis aims to prove the equality of the Hausdorff and ca- pacitary dimensions. Additionally, we establish the equivalence of Lebesgue and Hausdorff measures, which requires the Isodiametric inequality and ... -
Hlboko nepružný rozptyl miónov na priečne polarizovanom deutériu na experimente COMPASS
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2024)Datum obhajoby: 18. 6. 2024Nucleons consist of quarks and gluons. However, a deeper study of quarks is quite difficult, due to their almost immediate hadronization after leaving the nucleon (a process at the femtometre level). To describe the ... -
Štúdium lipozómov pomocou Ramanovej spektroskopie kvapkovo nanášaných povlakov
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2024)Datum obhajoby: 18. 6. 2024The method of drop coating deposition in Raman spectroscopy is based on the mea- surement of Raman spectra from a dried deposit of the studied sample, which is formed by drying a drop of a solution or suspension deposited ... -
Magnetooptika jako narušení symetrie materiálu
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2024)Datum obhajoby: 18. 6. 2024The optical response of a material is affected by many things, including magneti- zation. Experimentally, the magnetooptical part can be measured well, for the evaluation of experimental data it is important to be able to ... -
Plazmová elektrolytická oxidácia biodegradabilných horčíkových zliatin
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2024)Datum obhajoby: 18. 6. 2024Presented bachelor thesis is focused on the analysis of plasma electrolytic oxidation (PEO) preperation time effect on degradation resistance of pure Mg and WE43, Z1 and ZX10 alloys for its potential application in ... -
Bimetalické tenké vrstvy 3d kovů pro katalytickou konverzi CO2
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2024)Datum obhajoby: 18. 6. 2024In this thesis catalytic properties of copper on cobalt oxide substrate were researched. Two samples were prepared - one by sputtering copper on oxidized cobalt substrate and one by removing surface layers from the first ...
