Microstructure development in lithium lanthanum titanate solid electrolyte

Author(s): Petruša Borštnar (Author), Nina Daneu (Supervisor)

Year: 2025

Type: Doctoral dissertation

All-solid-state batteries are one of the key technologies for future energy storage and the transition to a climate-neutral society. They offer improved safety, stability, and a broader operating temperature range compared to conventional batteries with liquid electrolyte. Perovskite Li0.33La0.56 0.11TiO3 (LLTO) is recognized as one of the most promising solid …

Diagnosis and prognosis of solid oxide cell systems: a statistical approach

Author(s): Luka Žnidarič (Author), Đani Juričić (Supervisor)

Year: 2024

Type: Doctoral dissertation

Hydrogen is a promising energy carrier in the emerging green energy landscape. It is environmentally friendly, transportable, and storable. The Solid Oxide Cell (SOC) system is a complex technology that enables the bidirectional conversion of hydrogen to energy. The label SOC entails solid oxide fuel cell (SOFC) systems, which produce …

Room-temperature fabrication of electroceramic composites

Author(s): Nina Kuzmić (Author), Srečo Davor Škapin (Supervisor), Matjaž Spreitzer (Co-Supervisor), Heli Jantunen (Co-Supervisor)

Year: 2024

Type: Doctoral dissertation

In the scope of this thesis, I focused on SrTiO3 (ST)-based dielectric ceramic composites as a lead-free perovskite material, which holds great potential for use in various electronic components. Such materials are large-scale and fabricated under high energy requirements, indicating an increasing need for a more environmentally friendly processing method. …

Assessment of dimethyl sulphide odorous emissions released during the underground coal extraction in coal mine Velenje

Author(s): Gregor Uranjek (Author), Jože Kotnik (Supervisor), Radmila Milačič (Co-Supervisor)

Year: 2024

Type: Doctoral dissertation

Underground coal extraction at Coal Mine Velenje occasionally gives rise to odour complaints from local residents and irritates and disturbs the miners at work in the mine. This work describes a robust quantification of odorous emissions of mine sources and a model-based analysis aimed to establish a better understanding of …

Optimization of ToF-SIMS depth profiling in low-pressure H2, C2H2, CO and O2 atmosphere

Author(s): Jernej Ekar (Author), Janez Kovač (Supervisor)

Year: 2024

Type: Doctoral dissertation

Time-of-flight secondary ion mass spectrometry (ToF-SIMS) is a versatile analytical method widely used in the field of surface science and thin films. Although it gives elemental, molecular, and isotopic information, it has a very low detection limit and high lateral resolution, is fast and works with all the vacuum-compatible samples, …

Spatial and energy distributions of sputtered atoms in thin film deposition techniques

Author(s): Nastja Mahne (Author), Miha Čekada (Supervisor), Matjaž Panjan (Co-Supervisor)

Year: 2024

Type: Doctoral dissertation

The sputtering yield, the spatial distribution of the sputtered atoms, the energy distribution and the average energy of the sputtered atoms are important for numerous deposition techniques, as they determine the microstructure and the physical properties of the thin films. Using SRIM (Stopping and Range of Ions in Matter) simulations, …

Assessment of individual-level exposure to air pollutants using personal monitoring

Author(s): Rok Novak (Author), David Kocman (Supervisor)

Year: 2023

Type: Doctoral dissertation

A paradigm shift is occurring in the assessment of exposure to urban environmental stressors. Improved accuracy of personal monitors has enabled researchers to study exposure at the individual level. Monitoring stations are the primary reference point for air quality in urban environments, although there is a need to assess exposure …

Autonomous generation of robot behaviour for effective task execution

Author(s): Zvezdan Lončarević (Author), Andrej Gams (Supervisor)

Year: 2023

Type: Doctoral dissertation

The pursuit of autonomous robot learning is aimed at enabling robots to seamlessly integrate into our daily lives, enhancing our efficiency and convenience. On the other hand, in the industrial sector, autonomous robot learning plays a vital role in keeping up with the rapidly evolving market demands. As products and …

The effect of surface roughness on erosion yields and distribution of impurities on fusion relevant materials

Author(s): Mitja Kelemen (Author), Sabina Markelj (Supervisor), Primož Pelicon (Co-Supervisor)

Year: 2023

Type: Doctoral dissertation

Plasma facing components (PFC) in fusion devices are exposed to plasma. Plasma-wall interaction processes are important as they impose a series of constraints on the components. The lifetime of the PFCs is dominantly determined by two processes: erosion and fuel retention. At the first wall the erosion is caused by …

Development and application of molecularly imprinted polymers for selected antidepressants and studies of their environmental fate

Author(s): Tjaša Gornik (Author), Tina Kosjek (Supervisor), Ester Heath (Co-Supervisor)

Year: 2022

Type: Doctoral dissertation

This thesis focuses on the fate of chosen antidepressants in the environment. Studied compounds belong to the class of selective serotonin reuptake inhibitors. Reportedly they do not completely mineralize by existing water treatment processes and their residues cause unwanted toxic effects in aquatic organisms. However, to date, insufficient information has …
