Joanne Sharp PhD thesis: Electron Tomography of Defects
Supplementary data DVD
Welcome to the supplementary data DVD. This DVD contains movies of the reconstructions and tilt 
series presented in my thesis, Electron Tomography of Defects. If there are any that your computer 
cannot open, please contact me and we can find something that works: jhd28@cam.ac.uk. The 
movies correspond to the following parts of the thesis:
