1. Modeling Photofunctional Transition Metal Complexes
Sammanfattning : Transition metal complexes play a crucial role in solar energy conversion. These coordination compounds have promising applications in dye-sensitized solar cells and photocatalysis, with particular interest in solar fuel production. LÄS MER
2. Synthesis and Energy Transfer Studies of a Donor-Host-Acceptor Triad
Sammanfattning : This dissertation describes the synthesis of a donor-host-acceptor triad, D-H-A, and its self-assembly into a well-ordered dimer. The energy transfer (EnT) properties of D-H-A as it is, in the presence of a variety of guest molecules and in the dimeric form are presented. LÄS MER
3. Mechanisms of Mitochondria-Induced Brain Damage Following Ischemia and Hypoglycemia
Sammanfattning : Mechanisms of Mitochondria-Induced Brain Damage Following Ischemia and Hypoglycemia Following prolonged disruption of blood flow to the central nervous system (CNS), or energy deprivation by other means, such as hypoglycemia, some cells will inevitably degenerate. It has been, and still is, the subject of considerable debate and intense research on brain ischemia, as to the mode of cell death, i. LÄS MER
4. Global bifurcations and chaotic dynamics in physical applications
Sammanfattning : The aim of this work has been to analyse global bifurcations arising in a laser with injectedsignal and in a catalytic reaction on a surface of Pt, from the point of view of dynamicalsystems theory.The 3-dimensional ordinary differential equation which models the laser was found to contain a homoclinic orbit to a saddle-focus equilibrium, what corresponds to the Šil´nikov phenomenon.

5. Upconversion Detection for Improved Nonlinear Mid-infrared Spectroscopy in Flames
Sammanfattning : This thesis deals with the addition of upconversion detection to non-linear mid-infrared laser spectroscopy techniques. The techniques investigated here are degenerate four wave mixing (DFWM) and infrared polarization spectroscopy (IRPS). LÄS MER
