*  First-principles Investigation of Small Polarons in Metal Oxides
The polaron properties are obtained using a modified neutral potential-energy surface (PES). By changing the fraction of exact ... Finally, the approach is used to investigate the influence of the crystal structure on the polaron properties for rutile and ... Density-functional theory is often used for calculating properties of polarons. However, there are two challenges: sensitivity ... we derive the proper elastic long-range behavior of the polaron and a finite-size correction for the polaron properties. These ...

*  Functional iron oxide-based hybrid nanostructures
The effects of surface functionalities on the loading and distribution of iron oxide nanoparticles were studied by introducing ... This thesis describes diverse approaches of chemical functionalization as a general strategy to tailor material properties ... Particular attention was dedicated to the surface chemistry of iron oxide nanoparticles. Crystalline 10 nm-sized magnetite ... selected functionalities at the graphene oxide surface through diazonium chemistry. Finally, the development of a non-aqueous ...

*  Photophysical characterization and optimization of novel polymer based photosensitizer carrier systems for PDT
In the third part of this work, active tumour targeting behaviour achieved by surface modification of HSA and PLGA ... This work contains three main parts: First the photophysical properties of Pheo-HSA nanoparticles were compared to free ... It was found that the loading ratio determines the photophysical properties of both photosensitizer-loaded HSA and PLGA ... Intracellular singlet oxygen measurement reveals that HSA nanoparticles, both with antibody and PEG surface modification have ...

*  Etablierung der Rasterkraftmikroskopie an kardiovaskulär relevanten Zellen, Proteinen und Materialien
chapter 3.1.4.3). Assaying (qualitative and quantitative) the surface roughness properties of coronary artery stents, we found ... Finally these stents were coated with human thromboytes to investigate cell-stent-surface interactions. Surface-roughness ... Thereby it became feasible to high-resolution record the surface-properties of specimens (up to atomic resolution) at the ... We suppose, that changes in roughness of inner surface of coronary artery stents might induce clinical problems like acute ...
