1. 1. Exploring the effects of pressure on the magnetic properties of quasi-low dimensional quantum magnets via thermodynamic measurements

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Emelie Zhu; [2024]
   Keywords : Physics and Astronomy; Technology and Engineering;

   Abstract : Four model solid state compounds were used to experimentally investigate the effects of pressure on the interactions in one- and two-dimensional Heisenberg magnetic models. BaCuSi2O6, BaCu2V2O8, SrCuO2 and CuGeO3 were successfully synthesized via solid-state reactions and characterized via x-ray diffraction. READ MORE

3. 2. Stability improvement to a ruthenium catalyst for partial oxidation of methane

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Melker Axelsson; [2023]
   Keywords : catalysis; reaction engineering; kinetics; partial oxidation; chemical engineering; Technology and Engineering;

   Abstract : Catalytic partial oxidation of methane (CPOM) is an energy-efficient alternative to steam reforming, the currently prevailing method for energy production from natural gas. Hulteberg Chemistry & Engineering AB has developed a catalyst for the partial oxidation of methane into syngas, for use in solid oxide fuel cells. READ MORE

4. 3. Ventilation for reduced indoor spread of Covid 19 and similar diseases : A literature review focusing on hospital environments

   University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

   Author : Cyrus Ourak Pour; [2023]
   Keywords : COVID-19; SARS-CoV-2; Ventilation system; Mixing ventilation MV ; Displacement ventilation DV ; Under floor air distribution UFAD ; Ultraviolet light UV ; HEPA filter; COVID-19; SARS-CoV-2; Ventilationssystem; Blandningsventilation; Deplacementventilation; Luftfördelning under golv; Ultraviolett ljus; HEPA-filter;

   Abstract : Today, a significant portion of individuals’ time is spent indoors, estimated at approximately 90% of their total time. This raises concerns about the transmission of Coronavirus Disease 2019 (COVID-19) instigating Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and similar viruses and highlights the critical role of ventilation systems in indoor environments, which this study aims to investigate.

5. 4. Hydrogen storage systems : Methodology and model development for hydrogen storage systems performance evaluation based on a transient thermodynamic approach

   University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Author : Kreshnik Margaritari; [2023]
   Keywords : Hydrogen; Hydrogen storage system; Hydrogen filling process; Hydrogen storage system operation; Hydrogen storage system design; Hydrogen fast filling; Hydrogen tank modelling;

   Abstract : The overall performance of a hydrogen storage system can be affected by various parameters, such as operation and design parameters, but also by the state of the hydrogen contained inside the storage tanks. In this work, a methodology is developed to evaluate the state of the hydrogen during the filling process and its impact on the overall system performance under variable operation conditions and design parameters.

6. 5. Redox Materials in Hydrogen Production : Investigation of state-of-the-art redox materials in thermochemical cycles for hydrogen production via solar energy

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Saga Berneryd; [2023]
   Keywords : ;

   Abstract : This bachelor thesis work has investigated different redox materials in 2-step thermochemical water splitting processes for solar-driven hydrogen production. Materials have been mapped out by their results from experimental activity and by the conditions the tests were conducted in. READ MORE
