1. Advanced Fluorescence Microscopy to Study Plasma Membrane Protein Dynamics
Abstract : Membrane protein dynamics is of great importance for living organisms. The precise localization of proteins composing a synapse on the membrane facing a nerve terminus is essential for proper functioning of the nervous system. In muscle fibers, the nicotinic acetylcholine is densely packed under the motor nerve termini. READ MORE

2. Membrane-based nanocalorimetry for low temperature studies with high resolution and absolute accuracy
Abstract : A differential, membrane-based nanocalorimeter has been designed and constructed for thermal studies of mesoscopic samples at low temperatures. The calorimeter is intended for sample masses from mg to sub-μg and a broad temperature range from above room temperature down to the sub-K region. READ MORE

3. Innovations in nanomaterials for proton exchange membrane fuel cells
Abstract : Hydrogen technologies are rapidly receiving increased attention as it offers a renewable energy alternative to the current petroleum-based fuel infrastructure, considering that continued large-scale use of such fossil fuels will lead to disastrous impacts on our environment. The proton exchange membrane fuel cell should play a significant role in a hydrogen economy since it enables convenient and direct conversion of hydrogen into electricity, thus allowing the use of hydrogen in applications particularly suited for the transportation industry.

4. Fluorescence-based Transient State Monitoring for biomolecular, cellular and label-free studies
Abstract : Fluorophore blinking dynamics are highly sensitive to the local environment and can be used as an additional readout parameter to increase the information gained from existing fluorescence techniques.The origin of these blinking patterns are photophysical transitions to and from a manifold of non-luminescent states.

5. Nanocalorimetry of electronic phase transitions in systems with unconventional superconductivity and magnetic ordering
Abstract : In this thesis, low temperature specific heat measurements on small (μg) single crystals of different superconducting and magnetic systems are presented. The device used in this work features a combination of high sensitivity and good accuracy over the temperature range 1-400 K and allows measurements in high magnetic fields. READ MORE
