1. Cosmological Horizons and the Unruh Effect
L3-uppsats, Uppsala universitet/Teoretisk fysikSammanfattning : The black hole information paradox, which states that the evaporation of black holes due to Hawking radiation results in a violation of the conservation of quantum information, is arguably one of the most fundamental problems in all of modern physics. Through the equivalence principle, the essence of the problem can be understood and studied in the context of much simpler flat spacetime (described by the theory of special relativity); in this context the Hawking radiation takes the form of the so-called Unruh effect, a thermal effect in the vacuum of a Minkowski quantum field theory that can be measured by accelerated observers.

2. Investigation of new refrigerants for a large-scale heat pump and evaluation of system performance
Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : Heat production accounted in 2021 for 50 % of the energy end use globally, where a strongconnection to fossil sources still exists. Large-scale electrical heat pumps can therefore have akey role in the energy system to enable a decreased reliance on fossil fuels and at the same timecontribute to stable system when incorporating more intermittent renewable sources.

3. An investigation of rapeseed protein as a new food product
Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)Sammanfattning : The combination of a growing global population and a limiting amount of farmland creates a need for new innovative food products to achieve a global sustainable development and a healthy population. Rapeseed press cake is a low-cost by-product of rapeseed oil production and is very high in protein and fiber. LÄS MER
4. Effect of reversible permeabilization in combination with different drying methods on the structure and sensorial quality of dried basil leaves
Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)Sammanfattning : In this work the impact of different drying techniques and the stomata aperture induced by pulsed electric field (PEF) prior drying on quality of the dried products was assessed. The conditions of the electroporation treatment were chosen to induce an irreversible opening of the stomata of the basil leaves. LÄS MER
5. X-Ray Photoemission Spectroscopy Characterization of Fe(II)- and Fe(III)-Phthalocyanine Molecular Films
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Molekyl- och kondenserade materiens fysikSammanfattning : This thesis investigates the electronic structure of iron phthalocyanine (Fe(II)Pc) andiron phthalocyanine chloride (Fe(III)PcCl) immobilized on surfaces. For this purposetwo different deposition methods are used and compared: smearing the molecularpowder under atmosphere condition and evaporation of a molecular layer inultra-high vacuum. LÄS MER
