11. Multiscale modeling of nitride fuels
Sammanfattning : Nitride fuels have always been considered a good candidate for GENIV reactors, as well as space reactors, due to their high fissile density, highthermal conductivity and high melting point. In these concepts, not beingcompatible with water is not a significant problem. LÄS MER
12. Modeling of dose and sensitivity heterogeneities in radiation therapy
Sammanfattning : The increased interest in the use of light ion therapy is due to the high dose conformity to the target and the dense energy deposition along the tracks resulting in increased relative biological effectiveness compared to conventional radiation therapy. In spite of the good clinical experience, fundamental research on the characteristics of the ion beams is still needed in order to be able to fully explore their use. LÄS MER
13. Diagnosing Fuel Ions in Fusion Plasmas using Neutron Emission Spectroscopy
Sammanfattning : Neutron emission spectra, measured with the time of flight spectrometer TOFOR, at the joint European torus (JET) are presented in this thesis. TOFOR has been in use since 2005, routinely measuring the neutron emission from JET plasmas. LÄS MER
14. Modeling Quantum Cascade Lasers : The Challenge of Infra-Red Devices
Sammanfattning : We live in a time of rapid scientific and technological advancement. People liv- ing 100 years ago could never dream of inventions like those having completely changed our way of life, and our perception of the world; computers, mobile phones, the Internet, space travel, unraveling the mysteries of the early universe and distant galaxies, and our insight into the microscopic world of quantum phe- nomena.

15. Biomimetic Transition Metal Catalysts : Insights from Theoretical Modeling
Sammanfattning : The scientific interest in the chemistry of synthetic transition metal complexes is motivated by at least two arguments:1.These can be regarded as models of biological transition metal complexes, e.g. metalloenzymes, whose functions can be difficult to reveal in detail due to their complexity.
