11. Quantum Chemical Interpretation of Protein Crystal Structure
Sammanfattning : An initial model in the crystallographic structure determination process, usually contains many errors. To produce an accurate model, one must carry out several cycles of crystallographic refinement. LÄS MER
12. The mechanics in two nanosized systems : Size effect and threshold field
Sammanfattning : This thesis investigates the mechanics in two nanosized system. Paper I investigates a size effect in a cantilever nanowire affecting its resonance frequency. Paper II reveals a threshold field for the formation of a mound by the diffusion of surface atoms on a substrate under a STM-tip. LÄS MER
13. Assembling a toolkit for computational dissection of dense protein systems
Sammanfattning : The cellular interior is a dense environment. Understanding how such an environment impacts the properties of proteins and other macromolecules, as well as how weak, non-specific interactions drive processes such as protein droplet formation through liquid-liquid phase separation, is a major challenge in biological physics. LÄS MER
14. Luminescence properties of flexible conjugated dyes
Sammanfattning : In this licentiate thesis the luminescence properties of two flexible conjugated dyes have been studied. The first, Pt1, is a platinum(II) acetylide chromophore used in optical power limiting materials. LÄS MER
15. 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.
