31. There's Plenty of Room in Higher Dimensions - Nonlinear Dynamics of Nanoelectromechanical Systems
Sammanfattning : Nanoelectromechanical systems (NEMS) couple the dynamics of electrons to vibrating nanostructures such as suspended beams or membranes. These resonators can be used in for instance nanoelectronics and sensor applications. NEMS are also of fundamental interest since electrons exhibit strong quantum effects when confined in nanoobjects. LÄS MER
32. 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.

33. Light interactions in flexible conjugated dyes
Sammanfattning : In this thesis methodological developments have been made for the description of flexible conjugated dyes in room temperature spectrum calculations.The methods in question target increased accuracy and efficiency by combining classical molecular dynamics (MD) simulations with time-dependent response theory spectrum calculations.

34. First-principles studies of kinetic effects in energy-related materials
Sammanfattning : Quantum mechanical calculations based on first-principles (lat. ab initio) methods have over the past decades proved very successful for the study of many materials properties. LÄS MER
35. Electronic structure and optical properties of InGaAs and InAsP semiconductor quantum wires
Sammanfattning : In recent years intensive studies of semiconductor nanostructures or so-called semiconductor quantum structures have been performed in many research groups around the world. The research interest in quantum structures arises both from their potential to expose new physical phenomena in condensed matter physics, allied with fundamental quantum mechanical effects, and from their potential application in electronic and optoelectronic devices.
