6. Development and performance evaluation of accident-tolerant coated fuel claddings for light water reactors
Sammanfattning : The development of accident tolerant fuel has the aim of providing nuclear fuels able to endure severe accident conditions. Research in this field has also sparked a wave of material renewal in the nuclear industry that had been delayed for the last few decades. LÄS MER
7. Astrochemical Investigations of Complex Organics in Cold Molecular Cloud Cores
Sammanfattning : Astrochemistry is the study of the formation and evolution of molecules in the interstellar medium (ISM) of the Milky Way and other galaxies. Molecules start to accumulate in the coldest and densest regions of the ISM, namely molecular clouds, and as of this date, 307 interstellar molecules are identified. LÄS MER
8. Many-photon effects in time-resolved second harmonic generation from systems in optical cavities
Sammanfattning : Second harmonic generation is popular due to its numerous applications in different technologies dealing with multiple fields of science. The rapid technical advancement with the second harmonic generation demands parallel development in the theoretical understanding. LÄS MER
9. Development of Structural Steels for Powder Bed Fusion - Laser Beam
Sammanfattning : Over the past decade, powder bed fusion – laser beam (PBF-LB) has attracted noticeable attention from both academia and industry. However, there remains a scarcity of approved material for the process, as fewer than 40 alloys are commercially available. LÄS MER
10. Quantum Few-Body Physics with the Configuration Interaction Approach: Method Development and Application to Physical Systems
Sammanfattning : This dissertation, based on six included papers, theoretically investigates properties of quantum few-particle systems. An overview of related experimental research - ultra-cold trapped dilute gases, and electrons in quantum dots - is given, followed by a description of some of the studied many-particle phenomena - Bose-Einstein condensation, quantized vortices, Wigner localization and the Tonks-Girardeau gas.
