1. Light’EM up! : structural characterization of light-driven membrane protein complexes by cryogenic electron microscopy
Abstract : Photosynthesis is probably the most important process for allowing life to develop into the diverse forms we see today. In this process, solar radiation is used to convert CO2 into biomass. From this process, we obtain oxygen to breathe, sources of food (plant biomass), and the potential for clean and sustainable energy. READ MORE

2. Fast and reliable alignment and classification of biological macromolecules in electron microscopy images
Abstract : In the last century, immense progress has been made to charter and understand a wide range of biological phenomena. The origin of genetic inheritance was determined, showing that DNA holds genes that determine the architecture of proteins, utilized by the cell for most functions. READ MORE

3. Protein structure dynamics and interplay : by single-particle electron microscopy
Abstract : Single-particle cryo-electron microscopy (cryo-EM) is a method capable of obtaining information about the structural organization and dynamics of large macromolecular assemblies. In the late nineties, the method was suggested to have the potential of generating “atomic resolution” reconstructions of particles above a certain mass. READ MORE

4. The fracture mechanisms in duplex stainless steels at sub-zero temperatures
Abstract : The aim of the thesis was to study the susceptibility for brittle failures and the fracture process of duplex stainless steels at sub-zero temperatures (°C). In the first part of the thesis plates of hot-rolled duplex stainless steel with various thicknesses were used to study the influence of delamination (also known as splits) on the fracture toughness.

5. Structure studies of membrane associated proteins by transmission electron microscopy
Abstract : Cell membranes need to change their shapes during many cellular processeslike protein trafficking, cytokinesis and membrane homeostasis. The lattershuttles lipids, synthesized in the endoplasmic reticulum, to all membranouscompartments. READ MORE
