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

    Författare :Pernilla Nevsten; Centrum för analys och syntes; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. In-situ TEM Probing of Nanomaterials

    Författare :Magnus Hummelgård; Håkan Olin; Valeria Nicolosi; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanotechnology; in situ; TEM; probing; nanowires; nanoparticles; ink; Other engineering physics; Övrig teknisk fysik; Material physics with surface physics; Materialfysik med ytfysik; Condensed matter physics; Kondenserade materiens fysik;

    Sammanfattning : Nanomaterials because of their small size, may have special properties unlikely to be seen in ordinary types of materials. Nanomaterials like nanotubes,nanowires and nanoparticles are best studied at the nanoscale, vital but also problematic. LÄS MER

  5. 4. Organization of Nanoparticles in Solution-A TEM Study

    Författare :Olivier Balmes; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Materiallära; materialteknik; Material technology; organisation; plunge freezing; TEM; nanoparticle; transmission electron microscopy;

    Sammanfattning : A new approach to the study of nanoparticle systems has been introduced. Nanoparticle systems in aqueous and organic solutions have been synthesized and studied by transmission electron microscopy. These systems include nanoparticles of gold, silver, palladium, ruthenium, and platinum which have been stabilized using various ligands. LÄS MER

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

    Författare :István Zoltán Jenei; Stefan Csillag; Urban Wiklund; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; WS2 inorganic fullerene-like nanoparticles; lubrication; tribofilm; SEM; TEM; EELS; EDS; coating; surface analysis; friction; wear; titanium; material transfer; fysik; Physics;

    Sammanfattning : 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. LÄS MER
