11. Transglycosylation by Glycoside Hydrolases - Production and modification of alkyl glycosides
Sammanfattning : To enable the transition to a green, bio-based economy, an extensive enzymatic toolbox competitive to traditional chemical procedures is needed. One strong area for enzymes is carbohydrate chemistry, due to the over-functionalized nature of carbohydrates, difficult to handle in traditional chemistry. LÄS MER
12. Synthesis and Robotized Screening of Novel Perovskite Materials for Solar Cell Application
Sammanfattning : As of today, the energy consumption in the world is high and is essential in the development and growth of the modern-day society. The world energy consumption is projected to increase significantly over the next decades. LÄS MER
13. Producer Gas Implementation in Steel Reheating Furnaces from Lab to Industrial Scale : A Computational Fluid Dynamics and Thermodynamics Approach
Sammanfattning : The integrated steel-making plants in Sweden contributed with approximately 8 % of the total CO2 emissions in the country in 2011. A major contributor to these emissions is the combustion of fossil fuels in different process units. Therefore, it is essential to reduce emissions by limiting the fossil fuels consumption in the steel industry. LÄS MER
14. Ethanol from Softwood - Techno-Economic Evaluation for Development of the Enzymatic Process
Sammanfattning : Ethanol produced from renewable resources can be used to replace fossil fuels such as gasoline and diesel. This thesis deals with the development of the enzymatic process used for ethanol production from softwood. LÄS MER
15. Exploring low-carbon development pathways for Bolivia - A model-based analysis focused on the energy sector
Sammanfattning : Global emissions have continued to rise steadily at levels exceeding the 1.5°C climate stabilization target. Therefore, the increase in the average global temperature and climate change will be determined by how we handle greenhouse gas (GHG) emissions over the next years. LÄS MER
