6. Electricity access for human development in the Brazilian Amazon
Sammanfattning : Electricity access is widely recognized as a driver of development. The Brazilian government has incorporated this principle into its national rural electrification program, Luz Para Todos (LPT – Light for all), which has already benefited more than 14 million people in the country since its inception in 2003.

7. Atomistic Modelling of Materials for Clean Energy Applications : hydrogen generation, hydrogen storage, and Li-ion battery
Sammanfattning : In this thesis, a number of clean-energy materials for hydrogen generation, hydrogen storage, and Li-ion battery energy storage applications have been investigated through state-of-the-art density functional theory.As an alternative fuel, hydrogen has been regarded as one of the promising clean energies with the advantage of abundance (generated through water splitting) and pollution-free emission if used in fuel cell systems.

8. Thermodynamic and Kinetic Investigation of the Fe-Cr-Ni System Driven by Engineering Applications
Sammanfattning : This work is a thermodynamic and kinetic study of the Fe-Cr-Ni system as the core of stainless steels. The Fe-Cr, Fe-Ni and Cr-Ni systems were studied intensively using both computational and experimental techniques, including CALPHAD (CALculation of PHAse Diagrams), phase field simulation, ab initio modeling, calorimetry, and atom probe tomography.

9. Enhancing the Treatment of Systems Integration in Long-term Energy Models
Sammanfattning : Securing access to affordable energy services is of central importance to our societies. To do this sustainably, energy systems design should be – amongst other things – environmentally compliant and reconcile with the integrated management of potentially limiting resources. LÄS MER
10. Design of Internal Cooling Passages: Investigation of Thermal Performance of Serpentine Passages
Sammanfattning : Gas turbines are used to convert thermal energy into mechanical energy. The thermal efficiency of the gas turbine is directly related to the turbine inlet temperature. LÄS MER
