1. Development of Nonlinear Microscopy for Studies of Metabolism and Tissue Engineering
Sammanfattning : Nonlinear microscopy techniques provide abilities for noninvasive and selective imaging of structural and chemical properties of biological systems. These techniques include coherent anti-Stokes Raman scattering (CARS) microscopy with the ability to selectively image molecular vibrations, second harmonic generation (SHG) microscopy which selectively images fiber structures, and third harmonic generation (THG) microscopy which is sensitive to interfaces between materials with different optical properties.

2. Imaging materials with intermodulation : Studies in multifrequency atomic force microscopy
Sammanfattning : The Atomic Force Microscope (AFM) is a tool for imaging surfaces at the microand nano meter scale. The microscope senses the force acting between a surfaceand a tip positioned at the end of a micro-cantilever, forming an image of the surface topography. LÄS MER
3. Investigating nano-scale viscous and elastic forces withintermodulation : Studies in multifrequency atomic force microscopy
Sammanfattning : Investigating visco-elastic forces at the nanometer-scale is important to thecharacterization of soft materials. A quantitative force measurement can be ob-tained using an atomic force microscope (AFM) with a calibrated force transducer(the AFM cantilever). LÄS MER
4. Probing nonlinear electrical properties at the nanoscale : Studies in multifrequency AFM
Sammanfattning : Nanostructured materials promise great advances in diverse and active research fields such as energy harvesting and storage, corrosion prevention and high-density memories. Electrical characterization at the nanometer scale is key to understanding and optimizing the performance of these materials, and therefore central to the progress of nanotechnology. LÄS MER
5. Structural Studies Of Materials Using Time-Resolved X-ray Diffraction
Sammanfattning : This work consisted of the application of X-ray diffraction methods to the study of ultrafast phenomena in various materials. Since the X-ray pulses generated from the bending magnet at the MAX II ring, where most of the experimental work was conducted, have a duration of the order of 300 ps, they can not be used directly as probe pulses in experiments where higher temporal resolution is required.
