  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. Nanoparticle assisted tribofilm formation and material transfer studied with SEM and TEM

    Abstract : The discovery and subsequent synthesis of metal containing fullerenes- IFS (Inorganic Fullerene-like Structures) by R. Tenne et al. has generated considerable scientific interest with great potential impact in many industrial application areas such as lubrication. READ MORE

  6. 4. Development and application of advanced electron microscopy techniques for materials in biological systems

    Author : Pernilla Nevsten; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; multiple-unit drug; EFTEM; EELS; cyanine dye; SSAT; cryo-TEM; virus; TEM; apoptosis; SEM; AFm; α-TCP; apatite; XEDS; TEM grid; microscopy supports;

    Abstract : Theoretically, electron microscopy and scanning probe microscopy offer information on a scale beyond the optical microscope. However, the quality of the micrograph and the obtained information is limited by the sample preparation. READ MORE

  7. 5. Scanning electron microscopy (SEM) analysis of tribofilms enhanced by fullerene-like nanoparticles

    Author : István Zoltán Jenei; Stefan Csillag; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The beneficiary effects of WS2 inorganic fullerene-like nanoparticles in the lubrication industry were shown in recent years. The incorporation of the nanoparticles into lubricants (oils, greases) is however not straightforward. READ MORE
