1. Reducing the dynamical diffraction effects in EMCD by electron beam precession
University essay fromAbstract : Dynamical effects are known to reduce the signal to noise ratio in EMCD measurements making them highly dependent on sample thickness. Precession of the electron beam has been shown to reduce these effects in ordinary crystallography. READ MORE

2. Programming a TEM for magnetic measurements : DMscript code for acquiring EMCD data in a single scan with a q-E STEM setup
University essay from Uppsala universitet/Tillämpad materialvetenskapAbstract : Code written in the DigitalMicrograph® scripting language enables a new experimental design for acquiring the magnetic dichroism in EELS. Called the q-E STEM setup, it provides simultaneous acquisition of the dichroic pairs of spectra (eliminating major error sources) while preserving the real-space resolution of STEM. READ MORE

3. Structural elucidation of mRNA(Sirt1)-microRNA 34a complex
University essay from KTH/Skolan för teknikvetenskaplig kommunikation och lärande (ECE)Abstract : The aim of this thesis is to understand RNA-RNA interactions steering cellular functions, as in the case of this thesis the structure of mRNA(Sirt1) in complex with microRNA-34a (miR-34a). MiR-34a regulates the cancer protein p53 via Sirt1 modulation. READ MORE

4. Ro52 : Structure and interactions of constructs of RING and B-box
University essay from Linköpings universitet/Teknisk biologi; Linköpings universitet/Tekniska högskolanAbstract : The ubiquitination process is vital to maintain the protein homeostasis in the cell. With high specificity it regulates degradation of proteins by tagging them with a small protein called ubiquitin. Four proteins are involved to perform the process and in this thesis one of these proteins is studied. READ MORE
