1. Frequency comb Brillouin microscopy
Abstract : Brillouin light scattering (BLS), an almost a century-old technique, has evolved into a powerful and versatile method to study acoustic and magnetic phenomena down to the nanometer size scale. Presently, BLS can be applied in fields as diverse as acoustics, spintronics, geosciences, and biophysics. READ MORE

2. Parietal cell regeneration in rat gastric mucosal wounds : a quantitative light and electron microscopical study
Abstract : The aims of the study were to obtain a method with which it would be possible to produce standardized wounds in the gastric mucosa, and to follow the regeneration of the acid producing parietal cells in those lesions during different experimental conditions. Quantitative methods applied to light and electron microscopy were used. READ MORE

3. Laboratory soft x-ray microscopy and tomography
Abstract : Soft x-ray microscopy in the water-window (λ = 2.28 nm – 4.36 nm) is based on zone-plate optics and allows high-resolution imaging of, e.g. READ MORE

4. Phase-Contrast and High-Resolution Optics for X-Ray Microscopy
Abstract : X-ray microscopy is a well-established technique for nanoscale imaging. Zone plates are used as microscope objectives and provide high resolution, approaching 10 nm, currently limited by fabrication issues. This Thesis presents zone plate optics that achieve either high resolution or phase contrast in x-ray microscopy. READ MORE

5. Automating STED microscopy for functional and structural live-cell imaging
Abstract : Optical microscopy imaging methods are today invaluable tools for studies in life sciences as they allow visualization of biological systems, tissues, cells, and sub-cellular compartments from millimetres down to nanometres. The invention and development of nanoscopy in the past 20 years has pushed fluorescence microscopy down to the nanoscale, reaching beyond the natural diffraction limit of light that does not allow focusing of visible light below sizes of around 200 nm, and into the realm of what was previously only thought possible with electron microscopy.
