6. Development and applications of theoretical algorithms for simulations of materials at extreme conditions
Abstract : Materials at extreme conditions exhibit properties that differ substantially from ambient conditions. High pressure and high temperature expose anharmonic, non-linear behavior, and can provoke phase transitions among other effects. Experimental setups to study that sort of effects are typically costly and experiments themselves are laborious. READ MORE

7. Surface characterization and force measurements applied to industrial materials with atomic force microscopy
Abstract : The thesis focuses on the application of force measurements with atomic force microscopy (AFM) on materials with a few surface contacts/asperities and chemically modified surfaces. The technique allows measurements of ultra-small intermolecular and surface forces, down to the piconewton level. READ MORE

8. Physical Properties and Structural stability of carbon nanotubes under extreme conditions
Abstract : Carbon nanotubes (CNTs) have attracted an immense attention of the research community since reporting on this system by S. Ijima in 1991. A "single-walled" CNT (SWCNT) can be considered as a rolled-up single-layer graphene - a one atom-thick layer of carbon atoms arranged in a hexagonal lattice. READ MORE

9. Super resolution optical imaging – image analysis, multicolor development and biological applications
Abstract : This thesis focuses on super resolution STED optical imaging. STED provides a wealth of new informational content to the acquired images by using stimulated emission to surpass the diffraction limit in optical fluorescence microscopy. READ MORE

10. Development and application of ultra-sensitive fluorescence spectroscopy and microscopy for biomolecular interaction studies
Abstract : This thesis describes the development of sensitive and high-resolution fluorescence spectroscopic and microscopic techniques and their application to probe biomolecules and their interactions in solution, lipid membrane model systems and in cells. Paper I-IV are largely focused on methodological developments. READ MORE
