  1. 1. Transmission Electron Microscopy of Graphene and Hydrated Biomaterial Nanostructures Novel Techniques and Analysis

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Sultan Akhtar; Klaus Leifer; Hilborn Jöns; Stefano Rubino; Marco Cantoni; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene flakes; magnetic beads DNA coils; hydrated biomaterials; transmission electron microscopy; focused ion beam scanning electron microscopy; bright-field dark-field imaging; high resolution imaging; electron diffraction and cryogenic temperatures; Materialvetenskap; Materials Science;

    Abstract : Transmission Electron Microscopy (TEM) on light element materials and soft matters is problematic due to electron irradiation damage and low contrast. In this doctoral thesis techniques were developed to address some of those issues and successfully characterize these materials at high resolution. READ MORE
