21. Reducing Swedish Carbon Dioxide Emissions from the Basic Industry and Energy Utilities : An Actor and Policy Analysis
Sammanfattning : The aim of the thesis is to analyze the design of the present climate and energy policies. The main focus is on how the policy instruments affect the Swedish stakeholders who are included in the European Union’s Emission Trading Scheme (EU-ETS). LÄS MER
22. Phase-Contrast X-Ray Carbon Dioxide Angiography
Sammanfattning : Phase-contrast x-ray imaging is an emerging technology, which allows for imaging of smaller features than conventional absorption-based x-ray imaging, with lower radiation dose. Instead of the attenuation that is normally used in x-ray imaging, it utilizes the phase shift introduced by an object to the transmitted x-rays. LÄS MER
23. Atomic Scale Modelling in Photoelectrocatalysis : Towards the Development of Efficient Materials for Solar Fuel Production
Sammanfattning : Using sunlight to produce valuable chemicals has been pointed out as an interesting alternative to deal with the well-known environmental problem related to the use of fossil fuels for energy generation. Thus, it is crucial for this field the development of novel photocatalysts that could drive the uphill reactions with high efficiency while presenting low price and toxicity. LÄS MER
24. Ammonia-Based Post-Combustion Capture of Carbon Dioxide
Sammanfattning : Post-combustion capture of carbon dioxide is one of the measures to reduce emissions of carbon dioxide from large point source emitters. In post-combustion capture the carbon dioxide is absorbed from the flue gas by means of a liquid absorbent. LÄS MER
25. Thermodynamic Cycles using Carbon Dioxide as Working Fluid : CO2 transcritical power cycle study
Sammanfattning : The interest in utilizing the energy in low‐grade heat sources and waste heat is increasing. There is an abundance of such heat sources, but their utilization today is insufficient, mainly due to the limitations of the conventional power cycles in such applications, such as low efficiency, bulky size or moisture at the expansion outlet (e.g. LÄS MER
