  2. 6. 3D Electron Microscopy Methods and Applications : Structures from Atomic Scale to Mesoscale

    Author : Taimin Yang; Xiaodong Zou; Grüne Tim; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 3D Electron microscopy; continuous rotation electron diffraction; structure determination; data quality; electron tomography; mesoporous materials; zeolites; Inorganic Chemistry; oorganisk kemi;

    Abstract : The crystal structure determines the physical properties of a material. The structure can be analysed at different levels, from atomic level, mesoscale level, all the way up to the macroscale level. READ MORE

  4. 7. Design and characterization of nanoparticles and their assemblies : Transmission electron microscopy investigations from atomic to mesoscopic length scales

    Author : Arnaud Mayence; Lennart Bergström; Liberato Manna; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; electron microscopy; Materials Chemistry; materialkemi;

    Abstract : Transmission electron microscopy (TEM) is a powerful and versatile tool for investigating nanomaterials. In this thesis, various transmission electron microscopy techniques are used to study the chemical and structural features of different types of inorganic nanoparticles of well-defined morphologies as well as their assemblies.

  5. 8. 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

  6. 9. Image Processing in High Resolution Transmission Electron Microscopy of Inorganic Materials

    Author : Anna Carlsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Oorganisk kemi; Inorganic chemistry; electron diffraction; Electron microscopy; image processing;

    Abstract : High resolution transmission electron microscopy and digital image processing has been used to investigate the structure and properties of inorganic materials. The image processing was performed with the programming language Semper. All routines are listed in the appendix. READ MORE

  7. 10. The Multiple Faces of Interfaces : Electron microscopy analysis of CuInSe2 thin-film solar cells

    Author : Olivier Donzel-Gargand; Marika Edoff; Lionel Fourdrinier; Thomas Thersleff; Daniel Abou-Ras; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electron microscopy; TEM; STEM; EELS; EDS; solar cells; CIGS; ACIGS; CZTS; post deposition treatment; KF; RbF; buffer layers; interfaces; inter layers; barrier layers; passivation layers; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : The CIS solar cell family features both a high stability and world-class performances. They can be deposited on a wide variety of substrates and absorb the entire solar spectrum only using a thickness of a few micrometers. READ MORE
