1. Structural Studies of Large dsDNA Viruses using Single Particle Methods
Sammanfattning : Structural studies of large biological assemblies pose a unique problem due to their size, complexity and heterogeneity. Conventional methods like x-ray crystallography, NMR, etc. are limited in their ability to address these issues. To overcome some of these limitations, single particle methods were used. LÄS MER
2. Towards atomically resolved magnetic measurements in the transmission electron microscope : A study of structure and magnetic moments in thin films
Sammanfattning : The magnetic properties of thin metallic films are significantly different from the bulk properties due to the presence of interfaces. The properties shown by such thin films are influenced by the atomic level structure of the films and the interfaces. LÄS MER

5. Taming of Oxygen in the Electron Microscope : Effects of High Energy Electron Irradiation on O2 and Oxides
Sammanfattning : Transmission electron microscopy (TEM) is an atomic resolution technique that allows for in depth analysis of the properties of different materials by passing high energy electrons through a thin sample and detecting how they are affected. However, due to the strong interaction between electrons and matter, the probability of the sample remaining unperturbed by the electron irradiation is small. LÄS MER
