  2. 1. Mechanical behaviour of carbon nanostructures

    Author : Henrik Jackman; Krister Svensson; Pavel Krakhmalev; Eleanor E. B. Campbell; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbon nanotubes; CNT; multiwalled carbon nanotubes; MWCNT; rippling; buckling; mechanical properties; transmission electron microscopy; TEM; scanning electron microscopy; SEM; atomic force microscopy; AFM; Young’s modulus; in situ TEM; in situ SEM; Physics; Fysik;

    Abstract : AbstractCarbon nanotubes (CNTs) have extraordinary mechanical and electrical properties. Together with their small dimensions and low density, they are attractive candidates for building blocks in future nanoelectromechanical systems and for many other applications. READ MORE

  4. 2. Morphology of Polymers - Development of Electron Microscopy Methods

    Author : Helen Hassander; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SEM; TEM; polymer; electron microscopy; Polymer technology; biopolymers; Polymerteknik;

    Abstract : Most polymeric materials used today are not simple homopolymers, but consist of more than one polymer, which lead to morphologies of different length scale and shape. It is important to receive knowledge of the morphologies because the properties of the materials change depending on the structure. READ MORE

  5. 3. Quantitative Electron Microscopy Studies of Metal Nanoparticle Catalysts: Nanostructure, Support Interaction and Ageing Effects
